Description

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

[Prior Art] As a conventional shift lever device for an automatic transmission, for example, as shown in FIGS. 5 to 7, there is a shift lever 10 for an automatic transmission having an operating section 101.
3, a holding member 105 that is slidable along the longitudinal direction of the lever 103 and is biased upward;
an engaging body 111 supported by the holding member 105 and facing the guide groove 109 of the position plate 107; and an engaging body control section having one end connected to the holding member 105 and the other end provided in the operating section 101. 113 (push button) and a linking operating member 115 are respectively provided.

For example, the structure adopted by Jitsukaisho
There is a publication No. 59-92034.

[Problems to be solved by the invention] In such a shift lever device, the guide groove 1
The engaging body 111 facing 09 is switched to each position of traveling S, neutral N, reverse R, and parking P formed in the guide groove 109, but the engaging body 111 in the traveling position S is switched during driving. Because it is dangerous to switch directly to the reverse R and parking P positions, lanes (shift lanes) are provided for the reverse R and parking P positions in different positions from the lanes (driving lanes) for the neutral N and drive positions. safety is ensured. For this purpose, the switching of the reverse position R is started by first switching the engaging body 111 to the shift lane (dashed line in FIG. 7) by the engaging body control unit 113, and then switching from the driving lane to each position of reverse R or parking P. is now possible.

Therefore, it is necessary for the engaging body 111 to accurately switch between the driving lane and the shift lane.
For example, the engaging body 111 of the travel lane is set to face a position H approximately 0.5 mm from the guide groove edge, but if the position of the engaging body 111 is shifted toward the guide groove edge, it will come into strong contact with the groove edge. Sliding resistance occurs, making operation difficult and causing a feeling of lumpiness. In addition, if the shift lane is shifted, there is a risk of entering the reverse R position in some cases, so high assembly accuracy and component processing accuracy are required, which is undesirable in terms of assembly work and workability. Ta. Therefore, it is possible to adjust the connection stroke amount L by screwing the threaded portion 117 of the actuating member 115 into the holding member 105, but if the connection stroke amount differs after assembly,
Problems remain, such as the need to remove the operating section 101 and make adjustments again.

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

[Means for Solving the Problems] In order to achieve the above object, this invention includes a shift lever of an automatic transmission having an operating section, which is slidable along the longitudinal direction of the lever, and a holding member biased upward, an engaging body supported by the holding member and facing the guide groove of the position plate, one end connected to the holding member and the other end provided to the operating section. An adjusting means for adjusting the connection stroke amount of the actuating member is provided at the connecting portion between the holding member and the actuating member connected to the engaging body control portion, and a lever body of the shift lever facing the adjusting means is provided with an adjusting means for operating the adjusting means. It has a configuration with an opening.

[Operation] In such a shift lever device, if the engagement body becomes misaligned after assembly is completed,
A tool is inserted through the opening and the adjusting means is operated to adjust to the optimum position.

[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, reference numeral 1 denotes a shift lever having an operating portion 3. The base end of the lever 1 is rotatably supported on a base plate 7 via a lever shaft 5, and the shift lever 1 and the lever shaft 5 are integrally connected by a sleeve 9 and a connecting pin 11. The lever shaft 5 is also provided with a sleeve 9a and a connecting pin 11a.
An arm 13 is connected to the arm 13 via a wire 15 which extends from the arm 13 and is connected to an automatic transmission (not shown).

On the other hand, the shift lever 1 has a pin-shaped engaging body 1.
7 is provided, and the engaging body 17 is interlocked with a push button type engaging body control section 19 provided on the operating section 3 via a connecting mechanism 21a.

The engaging body 17 is penetratingly supported by a slidable holding member 23 incorporated in the internal space of the shift lever 1, and both ends thereof are connected to the lever body 1a of the shift lever 1.
It protrudes to the outside through upper and lower elongated holes 25 and 27 formed in the vertical wall surface, and one end faces into a guide groove 31 of a position plate 29, which will be described later.

The holding member 23 is formed in a cylindrical shape, and a spring 33 for urging the holding member 23 upward is interposed at the lower end, and an operating member 35 of the linking mechanism 21a is connected to the upper end.

The actuating member 35 extends upward along the inner space of the shift lever 1, and its extended end is connected to the cam body 37. This cam body 37 is connected to the engaging body control section 19.
are connected via a cam surface 39, and the cam surface 39 is
It forms an inclined surface that exerts a downward action on the actuating member 35 by pressing the engaging body control part 19 against the spring 41 incorporated in the operating part 3 (as indicated by the arrow in FIG. 1).

On the other hand, the holding member 23 is provided with an adjusting means 43 for adjusting the joining stroke amount L of the actuating member 35.

The adjusting means 43 includes a tapered portion 45a formed at the lower end of the actuating member 35 and abutting against the tapered portion 35a.
and a pressing body 45 having an axial center line W.
The head of the screw body 47 is provided with a minus groove or a plus groove 49 in which the tip of a tool such as a screwdriver is engaged.

The head of the screw body 47 is set at a position facing an opening 51 for operation, and the opening 51 is
A long hole 27 formed in the lever body 1a and guiding the engaging body 17 is utilized. Therefore, by inserting a tool through the opening 51 and moving the screw body 47 forward (solid line in FIG. 4), the welding stroke amount L can be reduced.
is minimized, and by retreating (solid line in Figure 2), the welding stroke amount L is maximized. As a result, the actuating member 35 moves up and down, and the stroke amount L
can be adjusted.

Note that the pressing body 45 may be a sphere. It is also possible to omit the pressing body 45 and make the tapered portion at the tip of the screw body 47 directly contact the tapered portion 35a of the actuating member 35.

Further, the position plate 29, which faces one end of the engaging body 17, is fixed to the base plate 7, and the guide groove 31 is provided with first speed, second speed,
Driving position consisting of D range, neutral, reverse,
Each parking position is formed.

In the shift lever device configured in this way, if the position of the engaging body 17 is misaligned after assembly is completed, after engaging the tip of a tool etc. with the plus groove 49 of the screw body 47, the screw By moving the body 47 forward and backward, the joining stroke amount L is adjusted and the engaging body 17 is set at an accurate position. Thereby, when the shift lever 1 is operated, the engaging body 17 correctly moves in each lane.

[Effects of the invention] As explained above, according to this invention, even if misalignment occurs after assembly is completed, the position of the engaging body can be easily adjusted from the outside, improving work efficiency. can be achieved.
