Description

  The present invention relates to a gate type shift lever device.

  In recent years, gate type shift lever devices are often used in automatic transmission vehicles. This gate type shift lever device has a parking range (P position), a reverse range (R position), a neutral range (N position), a drive range (D position), and the like as shift positions selected by the shift operation of the automatic transmission. Are provided with guide grooves arranged in a non-linear manner in a crank shape, and the shift lever moves along the shape of the grooves. The shift lever is urged in a direction substantially orthogonal to the selection direction of the shift position, and the lever is operated in the direction opposite to the urging direction and then moved in the selection direction. The vehicle can start and run.

Patent Document 1 below discloses a structure for biasing a shift lever. According to this, as shown in FIG. 9, a bent guide groove 106 is formed in the gate plate 121, and the shift lever 102 moves along the guide groove 106 and is held at a predetermined range position. ing. The shift lever 102 can be rotated in the shift direction by a shaft 108 (rotation center O1), and can be rotated in the select direction by a shaft 109 (rotation center O2). The shift lever 102 is provided with a plunger 104 that is pressed in a certain direction by a spring 105, and the shift lever 102 is urged toward one side of the guide groove 106 by the plunger guide portion 103. That is, the plunger 104 is pressed against the slope formed on the plunger guide portion 103 by the spring 105, and the plunger 104 and the shift lever 102 are urged to one side of the guide groove 106 by the action of the pressing reaction force. The shift lever 102 is held at each range position by this urging force.

  By the way, when the range position is changed, there is a problem that the shift lever 102 biased to one side comes into contact with the gate plate 121 and unpleasant sound is generated. For this reason, a contrivance is usually made to reduce the noise by providing a cushion 107 (buffer material). However, if this is done, the shift lever 102 moves while being pressed against the cushion 107 when performing a shift operation, which causes a problem that sliding resistance is generated and the operation feeling is deteriorated.

  On the other hand, in this type of shift lever device, conventionally, it has been regarded as important to improve the feeling of moderation (positioning feeling) when performing a shift operation.

  The present invention has been made in the background as described above, and in particular, it is an object to provide a gate type shift lever device which can obtain a good operation feeling by reducing sliding resistance and has an excellent moderation feeling. And

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the gate type shift lever device of the first invention is
A bent guide groove with a plurality of range positions set;
A shaft including a first axis rotatable in a predetermined direction and a second axis attached to the first axis and rotatable in a direction different from the first axis;
A shift lever that is supported by the shaft so as to be pivotable back and forth and left and right, moves in the guide groove by a shift operation, and is held at each range position;
Sliding means provided at one end of the shift lever;
An elastic force applying means provided on the shift lever and biasing the sliding means in a fixed direction;
The sliding means is pressed from an oblique direction, and an inclined surface is formed on which the sliding means slides in accordance with the shift operation, and the sliding means is applied in the direction in which the pressing force by the elastic force applying means and the vertical drag of the inclined surface are combined. Is added, and the force acts on the shaft as a fulcrum to bias the shift lever toward one side of the guide groove,
It is formed protruding from the inclined surface of the cam plate, and when the shift lever moves from a specific range position to the next range position adjacent to it, the shift lever moves from one side surface of the guide groove. A cam part for moving the sliding means in the direction of leaving;
The main feature is to have

  According to the first invention, the shift lever is provided with slide means biased in one direction by the elastic force applying means at one end, and the slide means is pressed from the oblique direction to the cam plate having the inclined surface, A force is applied to the sliding means in the direction in which the pressing force and the vertical drag of the inclined surface are combined. This force acts with the shaft as a fulcrum, and the shift lever is biased to one side surface of the guide groove. On the other hand, the cam plate is formed with a cam portion that protrudes from the inclined surface. When the shift lever moves from a specific range position (for example, N position) to the next range position (for example, D position), It becomes the appearance that gets over the cam part. At this time, the slide means moves in a direction in which the shift lever moves away from one side surface of the guide groove. More specifically, the sliding means is pressed against the cam portion from an oblique direction, and a force is applied to the sliding means in a direction in which the pressing force and the vertical drag of the cam portion are combined. This force acts with the shaft as a fulcrum, and the shift lever moves away from the side surface of the guide groove. Thereby, the sliding resistance of the shift lever is reduced and the operation feeling is improved. The elastic force applying means is, for example, a spring, and the sliding means is, for example, a ball that is rotatably held.

  Furthermore, according to the first invention, the moderation feeling of the shift lever can be improved. That is, once the shift lever is held at a specific range position (for example, N position), when moving to the next range position (for example, D position), the cam portion is contracted while the elastic force applying means (for example, spring) is contracted. Because it is necessary to get over, the shift lever will not move even if a little external force is applied, and rattling can be prevented. This improves the feeling of moderation.

The gate type shift lever device of the second invention is the one in the first invention,
The cam portion corresponds to a first moderation surface corresponding to a path in which the shift lever moves from a specific range position to an intermediate position toward the next range position, and a path in which the shift lever moves from the intermediate position to the next range position. The first moderation surface and the second moderation surface have a shape that includes the second moderation surface and a ridge line where the first moderation surface and the second moderation surface are in contact, and the first moderation surface and the second moderation surface have an elastic force so that the shift lever does not stop on the movement path. The pressing force of the sliding means by the applying means is always received from an oblique direction.

  According to the second aspect of the invention, the shift lever is difficult to stop during the shift operation, and the moderation feeling is further improved.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing the overall structure of a gate type shift lever device 1 according to the present invention. The gate type shift lever device 1 includes a gate plate 21 and a cushion 7 formed with a bent guide groove 6 (also called a staggered gate), a shift lever 2 that moves along the guide groove 6 by a shift operation, A shaft 10 that rotatably supports the lever 2 in the front-rear and left-right directions (X and Y directions in FIG. 1), a grip 11 that is attached to the tip of the shift lever 2, and a housing 12 are included. The shaft 10 intersects the first axis 8 (rotation center O1) which is the center for rotating the shift lever 2 in the shift range selection direction (Y direction in FIG. 1), and the shift lever 2 intersects the shift range selection direction. It is comprised from the 2nd axis | shaft 9 (rotation center O2) used as the center rotated in the direction (X direction of FIG. 1).

  A ball holder 13 is attached to the lower part of the shift lever 2, and the ball 4 (sliding means of the present invention) is rotatably held at the tip of the ball holder 13. A spring 5 (elastic force applying means of the present invention) is provided inside the shift lever 2, and the ball 4 is urged downward by the spring force of the spring 5 to press the ball 4 against the cam plate 3. When the shift lever 2 is moved by the shift operation, the ball 4 slides along the surface of the cam plate 3. The cam plate 3 is formed with an inclined surface and a cam portion, which will be described later, and restricts the movement of the ball 4.

  FIG. 2 shows a configuration example of the guide groove 6. In the guide groove 6, a parking range (P position), a reverse range (R position), a neutral range (N position), a drive range (D position), a third speed, a second speed, etc. are arranged in a non-linear crank shape. . If each range position is provided in a non-linear manner as described above, an erroneous operation during a shift operation is less likely to occur compared to a straight-type shift lever device provided in a straight line. Further, the shift lever 2 is urged to one side surface (S in FIG. 2) of the guide groove 6, and the shift lever 2 is held at each range position by this urging force. It does not move to the range position.

  Next, FIG. 3a shows an enlarged perspective view of the cam plate 3, and FIG. 3b shows an enlarged front view. Moreover, the AA arrow view of FIG. 3b, the BB arrow view, and CC arrow view are shown to FIG. 4 a, b, and c, respectively. In this way, the cam plate 3 is formed with the inclined surface 14, and the mountain-shaped cam portion 15 protruding from the inclined surface 14 and the spiral hole H for fixing the cam plate 3 are provided. As shown in FIG. 4c, the inclined surface 14 has an arc shape in the cross section of the cam plate 3 in the Y direction. That is, the inclined surface 14 is curved. This is because the shaft 10 is located above the cam plate 3 and the shift lever 2 is rotated around the shaft 10, so that the shape is matched to the trajectory of the ball 4. On the other hand, the cam portion 15 has a shape including a first moderation surface 16 and a second moderation surface 17 and a ridge line L where the first moderation surface 16 and the second moderation surface 17 are in contact with each other.

  FIG. 5 conceptually shows a path 18 in the guide groove 6 of the shift lever 2 and a path 19 of the ball 4 on the cam plate 3 corresponding thereto. The shift lever 2 is supported by the shaft 10 so as to be rotatable in the front-rear and left-right directions, and moves in the guide groove 6 by a shift operation. As the shift lever 2 moves, the ball 4 also moves on the cam plate 3. In the embodiment shown in FIG. 5, the ball 4 rides on the cam portion 15 when the shift lever 2 moves from the neutral N that is a specific range position to the drive D that is the next range position. Then, the ball 4 slides on the inclined surface 14 in the route from the parking P to the neutral N and the route from the drive D to the second speed. When the ball 4 slides on the inclined surface 14, the shift lever 2 is urged toward one side S of the guide groove 6 as will be described later. Further, when the ball 4 rides on the cam portion 15, the shift lever 2 moves away from the side surface S so as to draw an arc shape. Thereby, the sliding resistance between the shift lever 2 and the cushion 7 does not occur in the section from the neutral N to the drive D, and the operation feeling is improved.

  A cross-sectional view when the ball 4 slides on the inclined surface 14 is shown in FIG. An inclined surface 14 is formed on the cam plate 3, and the ball 4 is pressed from an oblique direction by the spring 5. A force F1 is applied to the ball 4 in the direction in which the pressing force F of the spring 5 and the vertical drag N1 of the inclined surface 14 are combined. The force F1 acts on the shaft 10 as a fulcrum to generate a force for urging the shift lever 2 in the opposite direction, that is, a force F2 for urging toward one side S of the guide groove 6. By this urging force F2, the shift lever 2 is held at each range position such as P, N, and D.

  Next, a cross-sectional view when the ball 4 gets over the cam portion 15 is shown in FIG. Thus, when the shift lever 2 moves from the neutral N toward the drive D, the ball 4 gets over the cam portion 15. At this time, the ball 4 moves in a direction in which the shift lever 2 moves away from the side surface S of the guide groove 6. More specifically, as shown in FIG. 7, the cam portion 15 is inclined in the opposite direction with respect to the inclined surface 14, and the ball 4 is pressed from an oblique direction when getting over the cam portion 15. A force F3 is applied to the ball 4 in the direction in which the pressing force F and the vertical drag N2 of the cam portion 15 are combined. The force F3 acts on the shaft 10 as a fulcrum to generate a force that biases the shift lever 2 in the opposite direction, that is, a force F4 that separates the shift lever 2 from the side surface S of the guide groove 6. As a result, no sliding resistance is generated between the shift lever 2 and the cushion 7, and the operation feeling is improved.

  Further, the presence of the cam portion 15 can prevent the shift lever from rattling. That is, as shown in FIG. 5, if the ball 4 is once held by the drive D, for example, in order to move to the neutral N, it is necessary to get over the cam portion 15 while compressing the spring 5. Even if it is added to the shift lever 2, the cam portion 15 cannot be overcome, and as a result, it is possible to prevent the shift lever 2 from rattling.

  On the other hand, as described in FIG. 3, the cam portion 15 has a shape including the first moderation surface 16 and the second moderation surface 17, and the ridge line L where the first moderation surface 16 and the second moderation surface 17 are in contact. . As shown in FIG. 5, when the shift lever 2 moves from the neutral N of the guide groove 6 to the intermediate position M to the drive D, the ball 4 moves on the first moderation surface 16 and from the intermediate position M to the drive D. When the shift lever 2 moves, the ball 4 moves on the second moderation surface 17. When the shift lever 2 passes the intermediate point M, the ball 4 is positioned on the ridge line L. Each of the first moderation surface 16 and the second moderation surface 17 always receives the pressing force of the ball 4 by the spring 5 from an oblique direction. As a result, when the ball 4 moves on the cam portion 15, a force to slide the ball 4 is generated in either the drive D or the neutral N, and it is difficult to stop halfway and the feeling of moderation is improved. Even when the shift operation is performed slowly with a light force, the ball 4 does not stop on the ridge line L or on the first and second moderation surfaces 16 and 17 and moves to either the D position or the N position. It will be. Here, as shown in FIG. 8, the cam portion 15 is formed in a round mountain shape so that the first moderation surface 16, the second moderation surface 17, and the ridge line L do not exist (although included in the first invention). As a result, a force F4 for releasing the shift lever 2 from the side surface S of the guide groove 6 is generated when moving from the drive D to the neutral N. As a result, the operation feeling is improved, but the vicinity of the top of the cam portion 15 is improved. Has a relatively flat shape, so that when the shift lever 2 is operated with a light force, the ball 4 is likely to stop at the top portion. For this reason, as shown in the second aspect of the present invention, it is easier to feel moderation when the shape has the first moderation surface 16, the second moderation surface, and the ridgeline L.

  In the embodiment described above, the cam portion 15 is formed between the drive D and the neutral N, but the present invention is not limited to this. For example, the cam portion 15 may be provided at a position corresponding to between D-3 and RN. In the above embodiment, the ball 4, the spring 5, the cam plate 3 and the like are arranged below the shift lever 2. However, for example, the same effect can be obtained even if arranged above as shown in FIG. .
