Description

[0001]
[Industrial applications]
The present invention relates to a shift lever and an automatic transmission operating device in an automatic transmission operating device for a motor vehicle.
[0002]
[Prior art]
The automatic transmission operating device of an automobile has a structure in which a position plate is formed on a support fixed to the vehicle floor, and the shift lever is supported by the support so that the shift lever can reciprocate back and forth. By pressing the knob button provided at the upper end, the position pin can be moved from one shift position (detent cutout) of the position plate to another desired shift position.
[0003]
The shift lever is rotatably supported by the support, and the position pin protrudes outside from the elongated hole opened diametrically opposite to the shift lever at the part facing the detent notch and The rod is supported through and the rod is housed in the shift lever pipe so that it can be urged upward by a spring disposed below and pushed down by the knob button.
[0004]
The position pin can engage with the detent cutout of the position plate formed on the support to set a desired shift position. However, when the shift position is in the parking position or at D2, the position pin is located at the end wall of the detent cutout. To form an anti-swinging (stopper) for the shift lever.
[0005]
[Problems to be solved by the invention]
However, when the vehicle stops running and the shift lever is pushed down to the parking (P) side, the operating force of the operator is too strong, the position pin hits the detent notch, and the end wall of the detent notch is worn. May be damaged or damaged. This is a problem that must be solved when the shift lever support is made of a resin molded body because the end wall of the detent cutout is made of resin. In addition, the position pin may be pressed against the detent notch and become unable to move upward, thereby deteriorating the operational feeling.
[0006]
In view of the above, the present invention provides a shift lever that prevents a position pin from abutting against a detent notch when a support body of the shift lever is made of a resin molded body.
[0007]
[Means for Solving the Problems]
A shift lever according to the present invention includes a support made of a resin molded body fixed to a vehicle floor, a pipe pivotally supported by the support, and a pair of pipes formed on the support from an upper end of the pipe. A skeleton portion extending in the shift groove formed between the position plates, a stopper formed of an enlarged portion formed at a lower end portion of the skeleton portion, and an interval through which the pipe can pass without being attached to the skeleton portion. And a pair of stoppers formed toward the shift groove side between the position plates so that the stoppers of the skeleton portion can abut after the skeleton portion is mounted, and formed on the position plate by being inserted into the elongated holes formed in the pipe. Pin engaged with the formed detent notch, a rod supporting the position pin and urged upward in the pipe, and a knob button for pushing down the rod Characterized by comprising the a.
[0009]
[Action]
When the shift lever is moved to the parking position, the stopper of the skeletal portion comes into contact with the stopper of the support to stop the swing. Therefore, if the position pins are set apart from each other without contacting the end wall of the detent cutout in a state in which the stoppers are in contact with each other, the support body is not worn or damaged. Also, the operational feeling is improved.
[0010]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a shift lever 2 is pivotally supported on a support 1 made of a resin molded body fixed to a vehicle floor 20 via a shaft 3 in a shift groove 17 so as to be able to swing back and forth. The shift lever 2 has a position pin 4 protruding from a long hole 6 formed in the pipe 5 on both sides of the pipe 5 and engaging with a detent cutout 7 formed in the support 1. The shift groove 17 is formed between a pair of position plates 11 formed on the support 1.
[0011]
As shown in FIG. 2, the support 1 is fixed to the vehicle floor 20 by sealing with a boot 21 interposed therebetween, the pipe 5 is connected to a hinge collar 22, and the hinge collar 22 is inserted through a shaft 23 and is rotatable. . The shaft 23 is fixed to the support 1 made of a resin molded product. A coil spring 24 is inserted into the pipe 5 of the shift lever 2, and a rod 8 is mounted on the coil spring 24, and the position pin 4 penetrates the rod 8 orthogonally. A knob button 10 contacts the upper end of the rod 8 so as to be able to be pushed down, and the knob button 10 is pushed in the horizontal direction.
[0012]
The shift lever 2 stands upright from the shift groove 17 of the support 1 at a predetermined height, and penetrates a slide plate 25 that is inserted substantially horizontally into the shift groove 17. The indicator 26 of the slide plate 25 is movably disposed below the scale plate 27 so that the shift position can be determined. The slide plate 25 is fitted into a cover 29 of an indicator box 28 fixed to the upper side surface of the support 1.
[0013]
As shown in FIGS. 1 and 3, an exterior body 14 is attached to the upper outer peripheral surface of the pipe 5 via a skeleton 12. The skeleton 12 is inserted into the pipe 5 and fastened to the pipe 5 with screws 15 together with the exterior body 14. The skeleton 12 is made of a hard resin, while the exterior body 14 is made of a soft resin. The skeleton 12 extends to a shift groove 17 formed between the pair of position plates 11.
[0014]
Further, a stopper 16 is formed at a lower portion of the skeleton 12. As shown in FIG. 4, the stopper 16 is an enlarged portion 13 of the skeleton 12 having a flat surface 16a on the front side (parking side) and an arc surface 16b on the rear side (drive side). The shift groove 17 for movement is formed so as to be movable. If any stopper against which the enlarged portion 13 contacts is formed on the support body 1 and the position pin 4 is kept away from the end wall of the detent cutout portion 7 in this case, The above objective is accomplished.
[0015]
Therefore, as shown in FIGS. 1, 2, and 4, a pair of stoppers 18 with which the stoppers 16 come into contact are formed integrally with the position plate 11. Each of the pair of stoppers 18 protrudes into the shift groove 17, and the front side is formed as an inclined surface 18b and the rear side is formed as a flat surface 18a, and the flat surface 16a contacts the flat surface 18a. The distance S between the stoppers 18 is slightly larger than the diameter of the pipe 5. Therefore, the pipe 5 can pass between the stoppers 18 (see FIG. 4). When the flat surface 16a of the stopper 16 and the flat surfaces 18b, 18b of the stopper 18 are in contact with each other, the position pin 4 is set so as not to contact the end wall of the detent notch 7. .
[0016]
The stopper 16 may be formed as a flat surface with the arcuate surface 16b formed as a flat surface, so that the same applies to the case where the shift lever 2 is pushed down to the rear side (D2). In addition, the stopper 16 is formed integrally with the skeleton portion 12 as the enlarged portion 13, but a separately prepared stopper may be inserted into the pipe 5 and fixed. Further, the stopper 18 is formed integrally with the position plate 11, but may be formed so as to project upward without projecting into the shift groove 17.
[0017]
Therefore, the operation of the above embodiment will be described. When the vehicle is stopped and the shift lever 2 is pushed down to the parking position while pushing the knob button 10, the flat surfaces 16a of the stoppers 16 become flat surfaces 18a, 18a of the pair of stoppers 18. To restrict the fall of the shift lever 2.
[0018]
At this time, since the position pin 4 does not come into contact with the end wall of the detent cutout portion 7 in the parking position, the position pin 4 is pushed upward by the coil spring 24 and then the position pin 4 is pushed down for traveling. At this time, since the position pin 4 is separated from the end wall of the detent notch 7, the end pin does not slidably contact the end wall.
[0019]
In addition, since the position pins 4 do not abut against the end wall of the detent cutout 7, the end wall is not worn or damaged. Moreover, since the stoppers 16 and 18 are made of resin, the impact sound is soft, so that the operator does not feel discomfort.
[0020]
Further, at the time of assembling, first, the pipe 5 is inserted into the shift groove 17 from below, and is supported on the support 1 by the shaft 23, and the exterior body 14 is attached from the upper end side of the pipe 5 protruding from the position plate 11. The skeleton 12 is inserted. Therefore, since the pipe 5 can pass between the pair of stoppers 18 when the pipe 5 is assembled, the workability in assembling is improved.
[0021]
【The invention's effect】
According to the invention described above, a stopper is formed in the skeleton portion of the exterior body of the shift lever, and a pair of stoppers that the stopper abuts may be formed in the shift groove of the support. The swing stop of the shift lever can be formed without contacting the end wall of the shift lever. Therefore, the end wall of the detent notch is not worn or damaged, and the operation feeling is good.
[0022]
In addition, since the skeleton and the exterior body are inserted through a pipe supported by the support and fixed with screws, the state plate and the exterior body are not mounted when the skeleton and the exterior body are not mounted. Since the pipe can pass through the stopper, the pipe can be tilted forward or backward at the time of assembling, and the assembling workability is improved.
[0023]
Further, since the stopper is made of resin, the impact sound is soft, so that the operator does not feel discomfort.
