Description

The present invention relates to a shift lever device operated to switch the operation of a transmission.

A vehicle equipped with a manual transmission (MT) is provided with, for example, a floor shift type shift lever device in the vehicle interior.

A shift lever device includes a shift body fixed to a floor in a vehicle compartment, and a shift lever supported by the shift body. The shift lever is tiltable in a select direction along the lateral direction of the vehicle and a shift direction along the longitudinal direction of the vehicle. When the shift lever is operated in the select direction (select operation), the operating force is transmitted to the manual transmission via the select cable, and the shift and select shaft of the manual transmission moves in the axial direction. Further, when the shift lever is operated in the shift direction (shift operation), the operating force is transmitted to the manual transmission via the shift cable, and the shift and select shaft rotates around the axis. A combination of these operations changes the meshing state of the gears of the manual transmission and configures the gear stage according to the select operation and shift operation of the shift lever.

FIG. 5 is an exploded perspective view schematically showing a conventional shift lever device.

A rotary cable hub 52 is provided in the middle of the shift cable 51 . On the other hand, an engagement groove 54 is formed in the shift body 53 . By engaging the rotary cable hub 52 with the engagement groove 54 , the shift cable 51 is positioned with respect to the shift body 53 in a direction other than the moving direction of the shift cable 51 due to the shift operation.

6 is a plan view of the rotatable cable hub 52. FIG. FIG. 7 is a side view of the rotatable cable hub 52 showing one side of the shift cable 51 relative to the centerline in cross section.

The rotary cable hub 52 has a cable insertion portion 61 , a stopper cap 62 , a socket 63 and a lock 64 .

The cable insertion portion 61 is rotationally symmetrical about the center line, and has a cable insertion hole 65 open at both ends on the center line. The shift cable 51 is inserted through the cable insertion hole 65 so as to be movable in the centerline direction. A screw 66 is formed on a part of the outer peripheral surface of the cable insertion portion 61 .

The stopper cap 62 is fixed to the cable insertion portion 61 and protrudes around the cable insertion portion 61 .

The socket 63 integrally has an annular plate-shaped threaded portion 67 and a cylindrical side portion 68 extending from the outer periphery of the threaded portion 67 to the side opposite to the stopper cap 62 side. A thread 69 is formed on the inner peripheral surface of the threaded portion 67 to be threaded with the thread 66 of the cable insertion portion 61 . Since the screws 66 and 69 are screwed together, when the socket 63 is rotated in one direction, the socket 63 moves toward the stopper cap 62, and when the socket 63 is rotated in the other direction, the socket 63 moves. It moves to the side opposite to the stopper cap 62 side. A disk-shaped (flat cylindrical) fitting portion 71 is formed on the surface of the socket 63 facing the stopper cap 62 side.

A torsion spring 72 is housed inside the side portion 68 of the socket 63 . The torsion spring 72 biases the socket 63 so that the socket 63 rotates and moves toward the stopper cap 62 .

The lock 64 is provided so as to be displaceable between an intervening position interposed between the stopper cap 62 and the socket 63 and a disengaged position separated from between the stopper cap 62 and the socket 63 . When the lock 64 is positioned at the interposition position, the lock 64 prevents the socket 63 from approaching the stopper cap 62 beyond the thickness of the lock 64 . When the lock 64 is displaced from the interposed position to the disengaged position, the socket 63 can move toward the stopper cap 62 , and the urging force of the torsion spring 72 causes the socket 63 to rotate and move toward the stopper cap 62 .

FIG. 8 shows a state where the rotary cable hub 52 is engaged with the engagement groove 54 of the shift body 53. As shown in FIG.

As shown in FIGS. 5 and 8, the shift body 53 has a plate-like plate portion 81 extending in the vertical direction, and an engagement groove 54 is formed in the plate-like portion 81 . The engagement groove 54 is composed of a circular holding hole 82 and an open groove 83 opening the holding hole 82 upward. The thickness of the plate-like portion 81 is smaller than the thickness of the stopper cap 62 . The holding hole 82 is formed to have a diameter that allows the fitting portion 71 formed in the socket 63 of the rotary cable hub 52 to be fitted without play (gap). Also, the open groove 83 is formed with a width smaller than the width of the lock 64 .

When the rotary cable hub 52 is engaged with the engagement groove 54 , the rotary cable hub 52 is brought close to the plate-like portion 81 from above, and is interposed between the stopper cap 62 of the rotary cable hub 52 and the socket 63 . The plate-like portion 81 enters, and the stopper cap 62 is positioned on one side of the plate-like portion 81, and the socket 63 is positioned on the other side. In this state, when the rotary cable hub 52 is inserted into the engagement groove 54 , the lock 64 comes into contact with the upper surface 85 of the plate-like portion 81 . After this abutment, when the rotary cable hub 52 is further inserted into the engagement groove 54, the lock 64 is displaced from the interposed position toward the disengaged position. When the fitting portion 71 of the socket 63 faces the holding hole 82 of the plate-like portion 81 in the direction of the center line of the holding hole 82, the stopper cap 62 is positioned at the disengaged position, and the biasing force of the torsion spring 72 causes the stopper cap 62 to move. The socket 63 rotates and moves toward the stopper cap 62 . When the fitting portion 71 of the socket 63 is fitted into the holding hole 82 of the plate-like portion 81 by the movement of the socket 63, the engagement of the rotary cable hub 52 with the engagement groove 54 is completed. When the fitting portion 71 is fitted in the holding hole 82 , there is no clearance exceeding the tolerance between the fitting portion 71 and the holding hole 82 , and the rotary cable hub 52 does not play against the plate-like portion 81 . It is attached.

However, in the conventional configuration, when the rotary cable hub 52 is inserted shallowly into the engagement groove 54 , the fitting portion 71 of the socket 63 does not move toward the center line of the holding hole 82 with respect to the holding hole 82 of the plate-like portion 81 . The lock 64 may be in the disengaged position even before the directions are opposed.

In this case, when the lock 64 is positioned at the disengaged position and the socket 63 approaches the stopper cap 62 , the plate-like portion 81 is sandwiched between the stopper cap 62 and the socket 63 , and the fitting portion 71 is inserted into the holding hole 82 . It doesn't fit. Therefore, if the shift operation is repeated, the rotary cable hub 52 may come off from the plate-like portion 81 and the shift operation may become impossible.

In the vehicle manufacturing factory, whether or not the rotary cable hub 52 is engaged with the engagement groove 54 is determined by an inspector visually confirming whether or not the lock 64 is positioned at the disengaged position. Therefore, it is difficult to prevent the vehicle from being shipped in a state in which the engagement of the rotary cable hub 52 with the engagement groove 54 is incomplete.

A shift body 53 of the shift lever device 1 includes a plate-like portion 2 .

An engaging groove 21 is formed in the plate-like portion 2 . The engaging groove 21 is composed of a holding hole 22 and an open groove 23 opening the holding hole 22 upward. The thickness of the plate-like portion 2 is smaller than the thickness of the stopper cap 62 . The holding hole 22 has a longer diameter in the vertical direction (engagement/disengagement direction of the rotary cable hub 52 with respect to the engagement groove 21) that is larger than the diameter of the fitting portion 71 formed in the socket 63 of the rotary cable hub 52. It is formed in an elliptical shape. Also, the open groove 23 is formed to have a width smaller than the width (longitudinal length) of the lock 64 of the rotary cable hub 52 .

A pair of restriction walls 25 and 26 are formed on the upper surface 24 of the plate-like portion 2 so as to extend upward from both sides of the engagement groove 21 . Each of the regulation walls 25 and 26 has a rectangular plate shape with the same thickness as the plate-like portion 2 . The dimension between the pair of restriction walls 25 and 26 is set to the dimension obtained by adding a predetermined value to the width of the lock 64 of the rotary cable hub 52 .

<Engagement operation of rotary cable hub>
2 and 3 are front views diagrammatically showing the rotary cable hub 52 and the plate-like portion 2, showing a state in which the rotary cable hub 2 is engaged (attached) to the engagement groove 21, respectively. show. FIG. 4 is a schematic front view of the rotary cable hub 52 and the plate-like portion 2, showing a state in which the rotary cable hub 2 is completely engaged with the engagement groove 21. FIG.

When the rotatable cable hub 52 is engaged with the engagement groove 21, the rotatable cable hub 52 is brought close to the plate-like portion 2 from above, as shown in FIG. At this time, the plate-like portion 2 enters between the stopper cap 62 and the socket 63 of the rotary cable hub 52, the stopper cap 62 is positioned on one side of the plate-like portion 2, and the socket 63 is positioned on the other side. placed in position.

From this state, the rotary cable hub 52 is inserted into the engagement groove 21 so that the lock 64 of the rotary cable hub 52 enters between the pair of regulation walls 25 and 26 without being caught. As the insertion of the rotary cable hub 52 progresses, the lock 64 comes into contact with the upper surface 24 of the plate-like portion 2 . After this abutment, when the rotary cable hub 52 is further inserted into the engagement groove 21, the lock 64 is displaced from the interposed position toward the disengaged position as shown in FIG.

Then, as shown in FIG. 4, when the fitting portion 71 of the socket 63 completely faces the holding hole 22 of the plate-like portion 2 in the center line direction of the holding hole 22, the stopper cap 62 is positioned at the disengaged position. Then, due to the biasing force of the torsion spring 72, the socket 63 rotates and moves toward the stopper cap 62 side. When the fitting portion 71 of the socket 63 is fitted into the holding hole 22 of the plate-like portion 2 by the movement of the socket 63, the engagement of the rotary cable hub 52 with the engagement groove 21 is completed.

<Effect>
As described above, the plate-like portion 2 is formed in the attachment/detachment direction in which the holding hole 22 and the release groove 23 are aligned, that is, the engagement/disengagement direction (attachment/detachment direction) of the rotary cable hub 52 with respect to the engagement groove 21 . The long diameter of the holding hole 22 is larger than the diameter of the fitting portion 71 formed in the socket 63 of the rotary cable hub 52 . Therefore, when the rotary cable hub 52 is attached to the engagement groove 21 , after the lock 64 comes into contact with the upper surface 24 of the plate-like portion 2 , the fitting portion 71 reaches a deep position where it completely faces the holding hole 22 . When the rotary cable hub 52 is inserted into the engaging groove 21, the lock 64 is displaced from the interposed position to the disengaged position. As a result, the fitting portion 71 fits well into the holding hole 22, and good engagement of the rotary cable hub 52 with the engaging groove 21 can be achieved. Therefore, in a vehicle manufacturing factory, even if an inspector visually confirms that the lock 64 is displaced to the disengaged position, the engagement of the rotary cable hub 52 with the engagement groove 21 is incomplete. It is possible to suppress the shipment of vehicles in a bad state.

On the upper surface 24 of the plate-like portion 2, a pair of restraints extend from both sides of the engagement groove 21 to one side to regulate the attitude of the lock 64 when the rotary cable hub 52 is inserted into the engagement groove 21. Walls 25, 26 are formed. Therefore, the rotary cable hub 52 is inserted into the engaging groove 21 in an oblique position, that is, in a position in which one end of the lock 64 contacts the upper surface 24 of the plate-like portion 2 and the other end does not contact the upper surface 24. can be suppressed. As a result, it is possible to prevent the lock 64 from being positioned at the disengaged position before the fitting portion 71 completely faces the holding hole 22, thereby achieving better engagement of the rotary cable hub 52 with the engagement groove 21. can do.

In addition, since the holding hole 22 is formed in an elliptical shape having a major diameter larger than the diameter of the fitting portion 71, there is a tolerance or more between the holding hole 22 and the fitting portion 71 fitted in the holding hole 22. A gap occurs. However, when the lock 64 is positioned at the disengaged position and the socket 63 approaches the stopper cap 62 , the plate-like portion 2 is sandwiched between the stopper cap 62 and the socket 63 , and the socket 63 engages the plate-like portion 2 as a torsion spring. Since it is pressed by the biasing force of 72, the fitting portion 71 does not rattle in the holding hole 22. - 特許庁Further, by using the reaction force of the shift cable 51 to press the fitting portion 71 against the inner peripheral surface of the holding hole 22, it is possible to further prevent the fitting portion 71 from rattling in the holding hole 22. .

<Modification>
Although the embodiments of the present invention have been described above, the present invention can also be implemented in other forms.

For example, in the above-described embodiment, the fitting portion 71 is formed in a circular shape and the holding hole 22 is formed in an elliptical shape. Well, the shape of the holding hole 22 is not limited to an elliptical shape either.

Moreover, although the shift cable 51 is taken up as an example of the cable, the cable may be a select cable.

The present invention can be applied not only to the shift lever device of manual transmissions but also to the shift lever devices of automatic transmissions such as AT (Automatic Transmission) and CVT (Continuously Variable Transmission).
