Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shift lever device for an automatic transmission, and more particularly to a gate type shift lever device in which operation of the shift lever is restricted by the shape of a gate groove.
[0002]
[Prior art]
Conventionally, this type of gate type shift lever device has a structure in which a gate groove (opening) is formed in the upper wall of the lever plate, and a shaft portion of the shift lever is inserted into the gate groove. Therefore, the movement of the shift lever is restricted by the shape of the gate groove, and the function of preventing the erroneous operation of the shift lever is performed.
[0003]
[Problems to be solved by the invention]
By the way, the specifications of the operation system for the transmission are different between the left-hand drive vehicle and the right-hand drive vehicle, and the shapes of the gate grooves are also symmetrical with each other. For this reason, the lever plate in which the gate groove is formed is a dedicated component for the left-hand drive vehicle and the right-hand drive vehicle, and cannot be shared.
[0004]
The object of the present invention is to make it possible to share a lever plate having a gate groove with respect to a difference in specifications between a left-hand drive vehicle and a right-hand drive vehicle.
[0005]
The object of the present invention is to make it possible to share a shift lever in addition to the above object.
[0006]
[Means for Solving the Problems]
The invention according to claim 1 is a gate type shift lever device in which the operation of the shift lever is restricted by the shape of the gate groove formed in the lever plate, and the shift lever has two axes whose axes are orthogonal to each other. A shift operation and a select operation are supported around the axis of one support shaft. This shift lever, thinner than the Oite shaft portion at a position offset, the detent pin is shorter provided from the shank.
The lever plate is formed with a pair of gate grooves formed so as to be symmetrical with each other on both the left and right sides . And it is comprised so that operation of a shift lever may be controlled by positioning a detent pin in any one gate groove.
[0007]
By selectively using the pair of gate grooves formed on both sides of the lever plate in this way, the lever plate can be shared with respect to the difference in specifications between the left-hand drive vehicle and the right-hand drive vehicle. .
[0008]
According to a second aspect of the present invention, there is provided the gate type shift lever device according to the first aspect, wherein the detent pin can be selectively fixed with respect to the left and right positions of the position offset from the shaft portion of the shift lever. ing.
[0009]
In this case, the shift lever can be shared with the lever plate by selecting the fixing position of the detent pin with respect to the shift lever.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
1 is an exploded perspective view showing a shift lever device of an automatic transmission, FIG. 2 is a sectional view showing the shift lever device, and FIG. 3 is a sectional view taken along line III-III in FIG. As shown in these drawings, the lever plate 10 has a box shape with its lower surface opened, and has a lever insertion opening 12 on the upper wall. On one side of the lever plate 10 on the lower surface side (the right side in FIGS. 1 and 2), shaft support portions 14 are formed on both the left and right sides in FIG. 3, respectively, and these have holes that can be supported on the coaxial line.
[0011]
The shift link 20 incorporated in the lever plate 10 has a support cylinder 22 at one end thereof. As shown in FIGS. 2 and 3, the support cylinder 22 is rotatably supported by a support shaft 40 between the shaft support portions 14. The support shaft 40 is provided with a head and is provided so as to penetrate from one side to the other side of the shaft support portion 14 as is apparent from FIG. 3, and is prevented from coming off by fixing a push nut 42 to the tip portion thereof. Further, a connecting pin 26 is fixed to the shift link 20 at the tip end opposite to the support tube 22, and an end 29 of the inner cable 28 in the shift cable is connected to the shift link 20, as shown in FIG. Yes.
[0012]
On the upper surface of the shift link 20, a pair of shaft support portions 24 are formed on an axis that is perpendicular to the axis of the support cylinder 22 (that is, the support shaft 40). A support cylinder 34 formed at the lower end portion of the shift lever 30 is rotatably supported by the support shaft 35 between the shaft support portions 24. The shaft portion 32 of the shift lever 30 is inserted into the lever insertion port 12 of the lever plate 10, and a lever knob 33 is coupled to the upper end thereof (FIG. 2).
[0013]
The shift lever 30 can be shifted around the axis of the support shaft 40 together with the shift link 20 and can be selected around the axis of the support shaft 35. This shift operation is transmitted to the automatic transmission through the shift cable (inner cable 28). The selection operation of the shift lever 30 is not directly related to the shift control of the automatic transmission.
[0014]
The shift lever 30 is integrally formed with an arm 36 at a location close to the support cylinder 34. A detent pin 38 is fixed upward at the tip of the arm 36. That is, the detent pin 38 is provided at a position offset from the shaft portion 32 of the shift lever 30, and the detent pin 38 is set to be thinner and shorter than the shaft portion 32 of the shift lever 30.
[0015]
Gate grooves 17 and 18 are formed in the left and right side portions 16 of the lever insertion opening 12 in the lever plate 10, respectively. The gate grooves 17 and 18 are symmetrical with each other. For example, in the case of a right-hand drive vehicle, the detent pin 38 is inserted into the left gate groove 17 as shown in FIG. Further, since the thicknesses of both side portions 16 are set to be relatively large (FIG. 3), the detent pin 38 adds to the edge of the gate groove 17 (or the gate groove 18) based on the operating force of the shift lever 30. Sufficient strength against load is secured.
[0016]
In the above configuration, when the shift lever 30 is shifted, the detent pin 38 moves in the gate groove 17 in conjunction with the shift lever 30. The movement of the detent pin 38 at this time is restricted by the shape of the gate groove 17, and thereby the shift operation of the shift lever 30 is restricted. In order to continue the shift operation while receiving this restriction, the shift lever 30 is selected according to the shape of the gate groove 17.
[0017]
Now, in the case of a left-hand drive vehicle, the arm 36 of the shift lever 30 protrudes to the right in FIG. 3 due to the difference in specifications, and the detent pin 38 is fixed thereto. Therefore, the detent pin 38 of the left-hand drive vehicle is inserted into the gate groove 18 of the lever plate 10, and the lever plate 10 can be shared with the left-hand drive vehicle and the right-hand drive vehicle.
[0018]
It is also possible to form the arms 36 of the shift lever 30 so as to project in the left-right direction in FIG. 3 so that the detent pins 38 can be selectively fixed thereto. Thereby, the shift lever 30 can be shared with the lever plate 10 according to the specifications of the left-hand drive vehicle and the right-hand drive vehicle.
Since the detent pin 38 is thin and rotates with a small rotation radius by operating the shift lever 30, both the groove width and length of the gate grooves 17 and 18 can be small, and the lever plate 10 can be made compact.
[0019]
Although the present embodiment has been described based on a floor shift type shift lever support device, the present invention can also be applied to a column shift type shift lever support device.
