Abstract

PROBLEM TO BE SOLVED: To attain compactness of a lever plate by allowing comparatively free setting of a position to form a gate groove and a range thereof with respect to the lever plate so as to enhance the degree of freedom of a design. SOLUTION: This device is a gate type shift lever device of such form that the shape of a gate groove on a lever plate 10 regulates operation of a shift lever 30. This device is provided with a detent pin 38 which is formed on a position offset to the shift lever 30 from a shaft 32 thereof and rotates in a smaller radius of rotation than that of the shaft 32 of the shift lever 30 by the operation thereof, and a gate groove 18 formed on the lever plate 10 for the detent pin 38 to be positioned therein. The device is formed such that the detent pin 38 and the gate groove 18 regulate operation of the shift lever 30.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field 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 the operation of the shift lever is restricted by the shape of a gate groove.

[0002]

2. Description of the Related Art Conventionally, this type of gate type shift lever device has a structure in which a gate groove (opening) is formed in an upper wall of a lever plate, and a shaft portion of the shift lever is inserted into the gate groove. ing. Therefore, the movement of the shift lever is regulated by the shape of the gate groove, and an appropriate operation is performed.

[0003]

The position and shape of the gate groove formed with respect to the lever plate are determined based on conditions such as the operability of the shift lever, the function for preventing erroneous operation, and the strength against the load from the shift lever. Limited. For this reason, the degree of freedom in design is low, and the lever plate becomes large as a whole.

[0004] It is an object of the present invention to make it possible to relatively freely set the position where the gate groove is formed with respect to the lever plate and the range of the gate groove, thereby increasing the degree of freedom of design and increasing the lever plate. The goal is to reduce the size.

Another object of the present invention is to make it possible to set the width of the gate groove to be small in addition to the above object.

[0006]

According to the first aspect of the present invention,
A gate-type shift lever device in which operation of a shift lever is restricted by a shape of a gate groove formed in a lever plate, wherein the shift lever device is provided at a position offset from a shaft portion of the shift lever, and the shift lever And a gate groove formed in the lever plate such that the detent pin is located, and a shift lever of the shift lever is formed by the detent pin and the gate groove. It is configured to regulate the operation.

By setting the detent pin so as to rotate at a position offset with respect to the shaft of the shift lever and with a smaller radius of rotation than the shaft of the shift lever, the gate groove is formed. It can be formed at a position shifted from the center of the lever plate and in a small area. That is, it is possible to relatively freely set the position where the gate groove is formed and the range of the gate groove, thereby increasing the degree of freedom in design and making the lever plate compact.

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 is set to be thinner than a shaft portion of the shift lever.

In this case, the width of the gate groove of the lever plate in which the detent pin enters can be reduced, and the lever plate can be made more compact.

Embodiments of the present invention will be described below. 1 is an exploded perspective view showing a shift lever device of the automatic transmission, FIG. 2 is a sectional view showing the same shift lever device, and FIG. 3 is a sectional view taken along line III-III of FIG. As shown in these drawings, the lever plate 10 has a box shape with an open lower surface, and has a lever insertion opening 12 in an upper wall. On one side of the lower surface of the lever plate 10 (the right side in FIGS. 1 and 2), bearing portions 14 are formed on both left and right sides in FIG. 3, respectively, and these have holes that can be bearing on a coaxial line.

The shift link 20 incorporated in the lever plate 10 has a support cylinder 22 at one end. This support cylinder 22 is rotatably supported by a support shaft 40 between the shaft supports 14 as shown in FIGS. The support shaft 40 has a head and is provided so as to penetrate from one side to the other side of the shaft support portion 14 as is clear from FIG. 3, and is prevented from falling off by fixing a push nut 42 to a tip end portion thereof. A connecting pin 26 is fixed to the shift link 20 at a distal end opposite to the support cylinder 22. An end 29 of an inner cable 28 of the shift cable is connected to the connecting pin 26 as shown in FIG. I have.

A pair of shaft supports 24 are formed on the upper surface of the shift link 20 on an axis orthogonal to the axis of the support cylinder 22 (ie, the support shaft 40). A support cylinder 34 formed at the lower end of the shift lever 30 is rotatably supported by a support shaft 35 between the shaft supports 24. The shaft portion 32 of the shift lever 30 is inserted into the lever insertion opening 12 of the lever plate 10, and a lever knob 33 is coupled to an upper end thereof (FIG. 2).

The shift lever 30, together with the shift link 20, can be shifted around the axis of the support shaft 40 and can be selectively operated around the axis of the support shaft 35. This shift operation is performed by the shift cable (inner cable 28).
Through the automatic transmission. Shift lever 3
The select operation of 0 has no direct relation to the shift control of the automatic transmission.

The shift lever 30 has a support cylinder 3
The arm 36 is integrally formed at a position close to 4. The arm 36 is moved from the axis side of the shaft portion 32 in FIG.
3 extends obliquely to the upper right, and extends therefrom to the left in FIG. The tip of the arm 36 has a detent pin 3
8 is fixed upward. That is, the detent pin 38 is provided at a position offset from the shaft portion 32 of the shift lever 30 and in a direction substantially perpendicular to the axes of the support shafts 35 and 40 (FIGS. 2 and 3).

The detent pin 38 is connected to the shift lever 3
It is set thinner and shorter than the shaft part 32 of 0. The detent pin 38 is located in a state of being inserted into the gate groove 18 formed in the part 16 of the upper surface of the lever plate 10. The gate groove 18 is provided between the two support shafts 3 more than the lever insertion opening 12 of the lever plate 10.
The groove width of the gate groove 18 is set to be small in accordance with the outer diameter of the detent pin 38. Further, the thickness of the part 16 of the upper surface of the lever plate 10 where the gate groove 18 is formed is set to be relatively large (FIG. 3). Therefore, the strength against the load applied from the detent pin 38 to the edge of the gate groove 18 based on the operation force of the shift lever 30 is sufficiently ensured.

In the above configuration, when the shift lever 30 is shifted, the detent pin 38 moves in the gate groove 18 in conjunction with the shift lever 30. At this time, the movement of the detent pin 38 is restricted by the shape of the gate groove 18, whereby 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 selectively operated according to the shape of the gate groove 18.

When the shift lever 30 is operated,
Since the detent pin 38 rotates with a small turning radius,
Since the length of the gate groove 18 is short and the groove width is small as described above, the lever plate 10 can be made compact. In addition, since the detent pin 38 is provided at a position offset from the shaft portion 32 of the shift lever 30 as described above, the gate groove 18 can be formed at an end shifted from the center of the lever plate 10.

Although the present embodiment has been described based on a floor shift type shift lever support device, the present invention can be applied to a column shift type shift lever support device.
