Description

  The present invention relates to a reverse misshift prevention structure in which a reverse shift of a shift lever is permitted by a push operation of a shift lever of a manual transmission.

Conventionally, as shown in Patent Document 1, for example, a reverse misshift prevention structure is known. This reverse miss shift prevention structure is designed to permit reverse shift of the shift lever by pushing the shift lever of the manual transmission. In the above-described reverse misshift prevention structure, a ball seat is slidably fitted in an upwardly projecting assembly hole of the retainer, and a ball provided at the center of the shift lever in the axial direction. The part is supported so that the shift lever can swing freely. The shift lever is urged upward by an urging spring accommodated in the assembly hole, and can be pushed against the urging force. A projecting portion is projectingly formed at the assembly hole opening of the retainer. The shift lever is also provided with a protrusion. When the shift lever is selected to the reverse side and the shift lever is not pushed, the shift lever protrusion comes into contact with the protrusion of the assembly hole opening and the shift lever moves to the reverse side. To regulate.

  However, in the above-described reverse misshift prevention structure, the entire shift lever is moved up and down together with the ball seat, so that the connecting member that connects the lower end of the shift lever and the control rod absorbs the vertical movement of the shift lever and becomes longer in the vertical direction. As a result, the overall height was high. Further, a space for slidably supporting the ball seat and a space for a spring for biasing the entire shift lever upward are required in the assembly hole. From the above, there has been a problem that the space in the vehicle interior becomes small.

  Accordingly, the present inventors have developed the following reverse misshift prevention structure in order to solve the above problem. That is, the shift lever is provided between the upper shift lever, the lower shift lever provided below the upper shift lever, and the upper shift lever and the lower shift lever. And a spring urging upward with respect to the side shift lever. The lower shift lever is constituted by a ball portion and a lever portion that is fixed to the ball portion so as to extend in the vertical direction and that slidably supports the upper shift lever. According to this structure, when the shift lever is pushed, only the upper shift lever moves downward relative to the lower shift lever. That is, the lower shift lever constituting the lower portion of the shift lever does not move up and down with the push operation of the shift lever. Therefore, the connecting member that connects the lower end portion of the shift lever (the lower end portion of the lower shift lever) and the control rod can be shortened up and down as compared with the prior art, and the overall height can be kept low. In addition, since a ball portion is provided on the lower shift lever and a spring is provided between the upper shift lever and the lower shift lever, there is a space for the ball seat and the spring in the assembly hole. It becomes unnecessary. As described above, space efficiency in the passenger compartment can be improved.

  Here, in the reverse misshift prevention structure, a member for preventing the upper shift lever from coming off the lower shift lever and a member for regulating the reverse movement of the shift lever are separately provided for the shift lever. Is provided. Therefore, this time, the present inventors have developed a reverse misshift prevention structure in which these members are integrated in order to further reduce the weight and size of the shift lever.

  The present invention has been made in view of such points, and the object of the present invention is to provide a reverse misshift prevention structure in which a reverse shift of the shift lever is permitted by a push operation of a shift lever of a manual transmission. The object is to provide a technology for reducing the weight and size of the shift lever.

A first invention is a reverse misshift prevention structure in which a reverse shift of a shift lever is permitted by a push operation of a shift lever of a manual transmission, the shift lever including a spherical ball member and the ball member A lower shift lever that is fixed so as to extend in the vertical direction and has a long hole extending in the vertical direction, and is supported by the lower shift lever so as to be slidable in the vertical direction, and a lever operation knob at the upper end portion. An upper shift lever provided with a pin, a pin fixed to the upper shift lever in a state of being inserted through the elongated hole portion, and a spring member for urging the upper shift lever upward. However, when the push operation is not performed, the spring member is positioned at the upper end of the long hole portion by the upward biasing of the spring member with respect to the upper shift lever. On the other hand, when the push operation is performed, the upper shift lever moves downward relative to the lower shift lever against the upward bias of the spring member, so that the upper shift lever moves downward from the upper end position of the long hole portion. And a base member having a support portion that is fixed to the vehicle body and supports the ball member so that the shift lever can swing in the shift direction and the select direction, and the base member. And a restricting member for restricting the reverse shift of the shift lever by contacting the pin only when the pin is positioned at the upper end of the elongated hole during the reverse operation of the shift lever. It is a feature.

  As a result, the pin prevents the upper shift lever from coming off the lower shift lever, prevents the upper shift lever from rotating about the lower shift lever, and reverse shifts the shift lever at a predetermined time. Play a regulatory role. Therefore, since it is not necessary to separately provide members having these functions, the number of members can be reduced.

  In a second aspect based on the first aspect, the lower shift lever is formed in a hollow shape having at least an upper end opened, and the elongated hole portion penetrates the lower shift lever in the radial direction. The upper shift lever is inserted and supported in the hollow portion of the lower shift lever so as to be slidable only in the vertical direction. .

  Here, since the upper shift lever is inserted and supported in the hollow portion of the lower shift lever, the pin is inserted from the long hole portion of the lower shift lever with the upper shift lever inserted into the hollow portion of the lower shift lever. By fixing to the upper shift lever, the pin can be fixed to the upper shift lever. That is, it is possible to fix the pin to the upper shift lever while observing the state of the upper shift lever inserted into the hollow portion from the long hole portion in which the state in the hollow portion of the lower shift lever is relatively easy to see. Therefore, the assembling property of this structure can be improved.

An annular elastic member fitted to the lower shift lever is further provided so as to be positioned between the protrusions.

  Thus, since the annular elastic member is fitted to the lower shift lever so as to be positioned between the pin and the protrusion, when the pin moves to the upper end position of the long hole portion by the biasing force of the spring member The pin moves from the lower side to the upper side while hitting the elastic member, and when the elastic member hits the protruding portion, the movement of the long hole portion to the upper end position is completed. In this way, when the pin moves to the upper end position of the long hole portion, the pin does not directly contact the upper end of the long hole portion, so that noise caused by the movement of the pin to the upper end position of the long hole portion can be prevented. .

  Further, since the elastic member is located between the protrusion and the pin, the pin also serves to prevent the elastic member from falling off the lower shift lever. Therefore, it is not necessary to separately provide a member for preventing the elastic member from falling off the lower shift lever.

  In a fourth aspect based on the second aspect, the spring member is incorporated in a hollow portion of the lower shift lever.

  Thereby, since the spring member is built in the hollow part of the lower side shift lever, it can prevent that the noise resulting from a spring member leaks outside, and can also prevent that a spring member rusts.

  A fifth invention is characterized in that, in the second invention, further comprising a moderation mechanism provided on the lower shift lever and imparting a moderation feeling to the operator when the shift lever is pushed. To do.

  As a result, a moderation mechanism that provides a moderation feeling to the operator during the push operation of the shift lever is provided in the lower shift lever, so that the operator's operation feeling during the shift lever push operation is improved. be able to.

  According to the present invention, the pin prevents the upper shift lever from coming out of the lower shift lever, prevents the upper shift lever from rotating about the axis of the lower shift lever, and regulates the reverse shift of the shift lever. In order to fulfill the role, it is not necessary to separately provide members having these functions. Therefore, the number of members can be reduced, and the shift lever can be made lightweight and compact. Furthermore, since the length of the shift lever can be shortened, the direct operational feeling of the shift lever can be improved.

Both ends of the guide pin 34 protrude in the select direction from the long holes 32b and 32b of the lower shift lever 32, and are guided only in the vertical direction by the long holes 32b and 32b. As a result, the guide pin 34 prevents the upper shift lever 33 from coming out of the hollow portion 32f of the lower shift lever 32 and prevents the upper shift lever 33 from rotating in the hollow portion 32f of the lower shift lever 32. Play a role to prevent. When the shift lever 30 is not pushed, the guide pin 34 is positioned at the upper ends of the long holes 32b and 32b by the upward biasing force of the spring 35 against the upper shift lever 33. The left end portion of the guide pin 34 positioned at the upper ends of the long hole portions 32b and 32b abuts on a regulating member 59 described later only when the shift lever 30 is in the 1-2 speed shift lane r1 (see FIG. 3). See dotted line). Thereby, the guide pin 34 plays a role of restricting the movement of the shift lever 30 toward the reverse shift lane r4 in the select direction only when the shift lever 30 is not pushed during the reverse operation of the shift lever 30 (this). Details of regulations will be described later). When the shift lever 30 is pushed, the guide pin 34 is moved by the upper shift lever 33 to move downward with respect to the lower shift lever 32 against the upward biasing force of the spring 35. It moves downward from the upper end position of 32b. The guide pin 34 also has a function of preventing the rubber member 40 from falling off the lower shift lever 32.

  The spring 35 is accommodated in the hollow portion 32 f of the lower shift lever 32. A part of the spring 35 is inserted into the spring recess 33 d of the upper shift lever 33. The upper end of the spring 35 is in contact with the bottom of the spring recess 33 d of the upper shift lever 33, while the lower end of the spring 35 is an outer peripheral surface of the select rod 36 inserted and fixed in the rod hole 31 b of the ball member 31. (See FIGS. 3 and 4).

And a ring 56.

  The shift lever hole 52 includes an upper hole 57 and a lower hole 58 located below the upper hole 57. The opening diameter (diameter) of the upper hole portion 57 is the same from the upper side to the lower side (see FIGS. 3 and 4). That is, the inner peripheral surface of the upper hole 57 is a vertical surface. The upper hole 57 is formed with three recesses 57a each having an inner peripheral surface recessed outward (see FIG. 5). These recesses 57a, 57a, 57a extend in the vertical direction. A bottom portion of the upper hole portion 57 is formed in a shelf shape (step shape) to constitute a shelf portion 57b.

  The opening diameter (diameter) of the lower hole 58 is smaller than that of the upper hole 57. The opening diameter of the lower hole portion 58 decreases linearly from the upper side to the lower side (see FIGS. 3 and 4). That is, the lower hole 58 is a so-called tapered hole. The lower hole 58 is provided with one recess 58a having an inner peripheral surface recessed outward (see FIG. 5). The recess 58a extends in the vertical direction.

  The upper and lower C-rings 54 and 55 are made of resin. The portions corresponding to the rod hole portions 53 of the upper and lower C-rings 54 and 55 are missing. The upper C-ring 54 has the same outer diameter from the upper side to the lower side, while the inner diameter decreases linearly from the upper side to the lower side (see FIGS. 3 and 4). . That is, the outer peripheral surface of the upper C ring 54 is a vertical surface, while the inner peripheral surface forms a tapered hole. Three protrusions 54a are formed on the outer peripheral surface of the upper C-ring 54 so as to protrude outward (see FIG. 5). These protrusions 54a, 54a, 54a extend in the vertical direction. The upper C-ring 54 is placed on the shelf 57b of the upper hole 57 with the bottom thereof and the protrusions 54a, 54a, 54a are fitted into the recesses 57a, 57a, 57a of the upper hole 57, respectively. It is fixed to. The lower C-ring 55 has a linearly decreasing outer diameter as it goes from the upper side to the lower side, while its inner diameter is curvilinearly smaller as it goes from the upper side to the lower side. That is, the outer peripheral surface of the lower C ring 55 is a vertical surface. In detail, the inner peripheral surface of the lower C-ring 55 is formed so that the gap with the ball member 31 increases from the lower side to the upper side when the shift lever 30 is not pushed. . The outer peripheral surface of the lower C-ring 55 is provided with one protrusion 55a that protrudes outward (see FIG. 5). The protrusion 55a extends in the vertical direction. The lower C-ring 55 is fixed to the lower hole 58 by placing the bottom of the lower C-ring 55 on the bottom of the lower hole 58 and fitting the protrusion 55a into the recess 58a of the lower hole 58. The ball member 31 is supported so as to be sandwiched between the upper and lower C-rings 54 and 55.

  On the upper surface of the vehicle rear side portion of the base member 50, the shift lever 30 moves toward the reverse shift lane r4 in the select direction only when the shift lever 30 is not pushed when the shift lever 30 is reversely operated. A regulating member 59 for regulating is installed. The restricting member 59 includes a restricting main body portion 59 a and a fixing portion 59 b for fixing the restricting member 59 to the base member 50. The restriction main body 59 a is located above the rod hole 53. The upper end portion on the right side surface in the select direction of the regulation main body 59a constitutes the contact surface 59c. The abutment surface 59c abuts the left end portion of the guide pin 34 only when the guide pin 34 is positioned at the upper end of the long hole portions 32b and 32b during the reverse operation of the shift lever 30 of the driver. A guide pin recess 59d (see FIG. 3) is formed on the lower side of the contact surface 59c on the right side in the select direction of the restriction main body 59a. In the guide pin recess 59d, the left end portion of the guide pin 34 is fitted when the shift lever 30 is pushed during the reverse operation of the shift lever 30 of the driver. The fixing portion 59b is a U-shaped plate member. The regulating member 59 is fixed to the base member 50 by fixing the fixing portion 59b to the upper surface of the base member 50 with four bolts. A part of the fixing portion 59b is bridged over the rod hole portion 31b.

−Operation of reverse misshift prevention structure−
Hereinafter, the operation of the reverse miss shift prevention structure 10 when the shift lever 30 is reversely operated will be described. Here, when the shift lever 30 is in the 1-2 speed shift lane r1, the left end portion of the guide pin 34 is in contact with the contact surface 59c of the regulating member 59 regardless of the position in the shift direction. Accordingly, when the driver reversely operates the shift lever 30 and does not push the shift lever 30, the left end portion of the guide pin 34 abuts against the abutment surface 59c of the restricting member 59 so that the shift lever 30 moves backward in the select direction. Movement to the shift lane r4 side is prohibited.

  On the other hand, when the driver reversely operates the shift lever 30, when the shift lever 30 is pushed, the protrusion 39b of the moderation mechanism 39 is disengaged from the moderation mechanism recess 33f of the upper shift lever 33, and the driver feels moderation. At the same time, the upper shift lever 33 moves downward relative to the lower shift lever 32 against the urging force of the spring 35. As the upper shift lever 33 moves downward with respect to the lower shift lever 32, the guide pin 34 also moves downward while being guided by the elongated holes 32b and 32b. When the guide pin 34 moves downward to the opening position of the guide pin recess 59d, the shift lever 30 can be moved toward the reverse shift lane r4 in the select direction. At this time, when the driver selects the shift lever 30 and hooks the left end portion of the guide pin 34 into the guide pin recess 59d, the shift lever 30 enters the reverse shift lane r4 and the shift lever 30 moves to the reverse position. Is possible.

-Effect-
As described above, according to the present embodiment, the guide pin 34 prevents the upper shift lever 33 from coming off the lower shift lever 32 and the upper shift lever 33 rotates about the axis of the lower shift lever 32. It plays a role of preventing the reverse shift of the shift lever 30 at a predetermined time. Therefore, since it is not necessary to separately provide members having these functions, the number of members can be reduced. Therefore, the shift lever 30 can be made lightweight and compact. Furthermore, since the length of the shift lever 30 can be shortened, the direct operational feeling of the shift lever 30 can be improved.

  Further, since the upper shift lever 33 is inserted and supported in the hollow portion 32f of the lower shift lever 32, the guide pin 34 is moved downward while the upper shift lever 33 is inserted into the hollow portion 32f of the lower shift lever 32. The guide pin 34 is inserted into the guide pin through hole 33e of the upper shift lever 33 from the one long hole portion 32b of the shift lever 32 and is inserted into the other long hole portion 32b. It can be inserted and fixed in the through hole 33e. That is, the guide pin 34 is moved to the upper shift lever 33 while viewing the state of the upper shift lever 33 inserted into the hollow portion 32f from the elongated hole portion 32b in which the state of the hollow portion 32f of the lower shift lever 32 is relatively easy to see. Can be fixed to. Therefore, the assembling property of the structure 10 can be improved.

  Further, since the annular rubber member 40 is fitted to the lower shift lever 32 so as to be positioned between the guide pin 34 and the lower end surface of the extended portion 32c of the lower shift lever 32, the guide pin 34 is fitted to the spring 35. When the guide pin 34 contacts the rubber member 40, the guide pin 34 moves from the lower side to the upper side while the rubber member 40 moves upward. The movement to the upper end position of the long hole portions 32b and 32b is completed by hitting the lower end surface of the extended portion 32c. Thus, when the guide pin 34 moves to the upper end position of the long hole portions 32b, 32b, the guide pin 34 does not directly contact the upper end of the long hole portions 32b, 32b. It is possible to prevent noise caused by the movement to the upper end position of 32b.

  Further, since the rubber member 40 is located between the lower end surface of the extension portion 32 c and the guide pin 34, the guide pin 34 also serves to prevent the rubber member 40 from falling off the lower shift lever 32. Therefore, it is not necessary to separately provide a member for preventing the rubber member 40 from falling off the lower shift lever 32.
