Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a shift lever device for an automatic transmission.

[Prior Art] Conventionally, as a shift lever device for an automatic transmission that shifts a lever in a neutral position to, for example, each position of driving, reversing, or parking,
There is a description in Publication No. 59-92034, etc.

For example, as shown in FIGS. 5 to 7, this shift lever device is slidable in a lever 103 of an automatic transmission having an operating section 101 along the longitudinal direction of the lever 103, and is arranged upwardly. The slider 105 is urged toward the slider 105 and the guide groove 10 of the position plate 107 is supported by the slider 105.
9 and the slider 1
05, and the other end thereof is connected to a pressing member 113 (push button) provided on the operating section 101.

Note that 119 indicates an operating arm connected to an automatic transmission section (not shown).

[Problems to be solved by the invention] In such a shift lever device, the guide groove 1
The position pin 111 facing 09 is in the guide groove 1.
Although the position pin 111 in the driving position S is switched directly to the driving position S, the position pin 111 in the driving position S is directly switched to the driving position R or the parking position P during driving. To ensure safety, lanes (shift lanes) are provided at different positions with a difference in level from the lanes for the neutral N and drive position S for the reverse R and parking P positions. For this reason, the reverse position R can be switched from the driving lane to the reverse R or parking position P by switching one end of the position pin 111 to the shift lane (dashed line in FIG. 7) using the pressing member 113. It's summery.

Therefore, it is necessary for the position pin 111 to accurately switch between the driving lane and the shift lane, and the position pin 111 for the driving lane is
For example, it is set to face a position H approximately 0.5 mm from the edge of the guide groove. In this case, if the position pin 111 is misaligned toward the edge of the guide groove, it will come into strong contact with the edge of the groove and generate sliding resistance, making the operation heavier or causing a feeling of roughness. begin to suffer. In addition, if the shift lane goes out of alignment, there is a risk that the shift will go into the reverse R position.
It is necessary to readjust the threading allowance by turning 7.
This re-chobushi work was very tedious.

Therefore, it is an object of this invention to provide a shift lever device for an automatic transmission that can be easily adjusted from the outside even if the position becomes incorrect after assembly is completed.

[Means for Solving the Problems] In order to achieve the above object, this invention includes a lever rotatably supported on the vehicle body, an operating portion provided at the upper end of the lever, a slider connected to the operating portion via an actuation rod and capable of vertical movement within the lever; and a position pin fixedly supported by the slider and protruding into a guide groove of a position plate fixed to the vehicle body. In the shift lever device, the slider and the actuating rod are connected to each other so as to be relatively movable in the vertical direction by an axially movable and rotatable connecting shaft, and the connecting shaft is connected to the connecting shaft from the outside. A restraining means is provided that allows rotation of the connecting shaft when pressing in the axial direction and restrains rotation of the connecting shaft when the pressing is released.

[Function] In such a shift lever device, if the position pin is misaligned after assembly is completed, the connection shaft is operated from the outside to move the slider and the actuating rod relative to each other in the vertical direction. After adjusting to the optimum position, if the pressure on the connecting shaft is released, the connecting shaft is restrained by the restraining means, and a correct positioning state can be quickly obtained.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 4.

In the figure, 1 indicates a lever having an operating section 3. The base end of the lever 1 is rotatably supported by a base plate 7 via a lever shaft 5, and the lever 1 and lever shaft 5 are connected to a sleeve 9 and a connecting pin 11.
are in a united state due to Further, an arm 13 is integrally connected to the lever shaft 5 via a sleeve 9a and a connecting pin 11a, and the arm 13 is connected to an automatic transmission (not shown) via a wire.

On the other hand, the lever 1 is provided with a position pin 17, and the pin 17 is interlocked with a push button type pressing member 19 provided on the operating section 3 via a link mechanism 21.

The position pin 17 is penetrated and supported by a slidable slider 23 built into the internal space of the lever 1, and both ends thereof are inserted into upper and lower elongated holes 25, 27 formed in the peripheral wall surface of the lever body 1a of the lever 1. It protrudes to the outside through the base plate 7, and one end faces into the guide groove 31 of the position plate 29 that stands up from the base plate 7. The guide groove 31 is provided with parking P, reverse R, neutral N, and running S positions.

The slider 23 is formed in a rectangular shape, and a spring 33 for biasing the slider 23 upward is interposed at the lower end, and an actuating rod 3 of the linking mechanism 21 is installed at the upper end.
5 are connected.

The actuating rod 35 extends upward along the inner space of the shift lever 1, and its extended end is connected to a cam body 37. This cam body 37 is connected to the pressing member 19 via a cam surface 39, and the cam surface 39 presses the pressing member 19 against the spring 41 incorporated in the operating section 3 (arrow in FIG. 1). This creates an inclined surface on which the actuating rod 35 moves in a downward direction.

The actuating rod 35 and the slider 23 are connected by a connecting shaft 43 so as to be relatively movable in the vertical direction.

One end of the connecting shaft 43 passes through an elongated hole 45 in the vertical direction formed in the slider 23, faces the opening 47 of the lever 1 provided opposite to the elongated hole 45, and the end on the side of the opening 47 A minus groove 49 into which the tip of the tool 51 is inserted is provided in the section.

Further, a rotating gear 53 is fixed to the connecting shaft 43, and the rotating gear 53 is provided with a pinion gear portion 53a and a bevel gear portion 53b, respectively, which mesh with a vertical rack 55 formed on one of the inner sides of the slider 23. , the bevel gear portion 53b is the slider 23
It is capable of meshing with an inclined rack-shaped fixed gear portion 57 provided parallel to the rack 55 on one side. Bevel gear part 53b and fixed gear part 5
7 is constantly engaged with the rotating gear 53 by a biasing spring 59 interposed on one side thereof.

That is, since the bevel gear portion 53b is in mesh with the fixed gear portion 57 at two locking points, the rotating gear 53 is in a state of being restrained at the meshing position of the bevel gear portion 53b.

Note that 61 indicates an allowance for the bevel gear portion 53b to come off from the fixed gear portion 57 when the connecting shaft 43 is pressed against the biasing spring 59.

In the shift lever device configured as described above, if the position pin 17 becomes misaligned after assembly is completed, the tip of the tool 51 is engaged with the minus groove 49 of the connecting shaft 43, and then the biasing spring is 59 and press the connecting shaft 43. At this time, the connecting shaft 43 moves in the axial direction and the bevel gear part 5
3b is released from the fixed gear portion 57 and is in a released state, so it is rotated to the right or left while remaining in the pressed state.
As the rotary gear 53 rotates, the rack 55, that is, the slider 23, which engages with the pinion gear portion 53a of the gear 53, moves upward or downward relative to the actuating rod 35, and the optimum position of the position pin 17 is determined. Next, when the tool 51 is removed at the positioned position, the bevel gear part 53b meshes with the fixed gear part 57 again and the rotation gear 53 is restrained, so that the optimum position of the position pin 17 can be obtained.
