Abstract

PROBLEM TO BE SOLVED: To provide a shift lever device capable of confirming a position of each shift range by a tactile sense at the time of operating a shift lever. SOLUTION: A curved moderate plate 40 is installed on a back surface of a shift plate 36 in accordance with a moving locus of a moderate pin 32. A semi-spherically recessed moderate groove 42 is recessively provided in correspondence with each shift range position roughly in parallel with a guide groove on the moderate plate 40, and it is devised so that a head part of the moderate pin 32 energized by a coil spring 30 enters it by operation of a shift lever 12. When the shift lever 12 is operated back and forth and left and right along the guide groove, the moderate pin 32 enters the moderate groove 12 in correspondence with a specified shift position in accordance with operation of the shift lever 12 by drawing a circular orbit and goes out of it. Consequently, it is possible to confirm a position of each shift range by a tactile sense at the time of operating the shift lever 12.

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 used for a transmission of a vehicle.

[0002]

2. Description of the Related Art A shift lever for shifting an automatic transmission is inserted into a guide groove of a box-shaped housing and moved along the guide groove to select an arbitrary shift range.

By the way, in the case of a manual mission vehicle, when the shift range is changed, it is possible to confirm that the shift is performed by the tactile sensation of the operation transmitted from the shift lever.

However, in the shift lever device for an automatic transmission, the operation direction of the shift lever is the vehicle longitudinal direction.
Alternatively, in the case of the gate type, since it is zigzag including the front, rear, left and right of the vehicle, the shift range cannot be confirmed by the tactile sensation when operating the shift lever.

[0005]

SUMMARY OF THE INVENTION In consideration of the facts described above, an object of the present invention is to provide a shift lever device capable of confirming the position of each shift range by the tactile sensation when operating the shift lever.

[0006]

According to the present invention, when the shift lever is operated along the guide groove formed in the shift plate, the moderation pin moves together with the shift lever, and every time the shift range is selected. Then, it goes into the moderation groove provided on the shift plate corresponding to the shift range.
Therefore, the position of each shift range can be confirmed by the tactile sensation when the shift lever is operated.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a shift lever device 10 according to this embodiment includes a shift lever 12 for a shift operation.

The lower end of the shift lever 12 is attached to the block 14. A pair of brackets 16 are provided so as to project from the block 14, and the brackets 16 are mounted on a tubular shaft 18 and connected by pins 20. This allows the block 14 to rotate in the axial direction of the shaft 18. Also, the shaft 18
Is rotatably supported by the control shaft 22 and the block 1
4 is rotatable about the axis of the shaft 18.

As a result, the shift lever 12 can rotate in the front-rear direction of the vehicle about the control shaft 22 and can rotate in the width direction of the vehicle about the pin 20.

A control lever 24 extends from the shaft 18, and a pin 26 provided at the tip of the control lever 24 is connected to an automatic transmission through a transmission mechanism (not shown). It is designed to shift the automatic transmission.

On the other hand, the block 14 is formed with a storage hole 28 which opens in an obliquely upward direction. A coil spring 30 is stored in the storage hole 28, and further,
A moderation pin 32 having a hemispherical head is pushed in. As a result, the moderation pin 32 causes the shift plate 3 to move.
It is urged toward 6.

As shown in FIG. 2, a guide groove 38 is formed in the shift plate 36 and the shift lever 12 is inserted therethrough. The guide groove 38 is a so-called gate type that is bent in a zigzag direction in the front-rear and left-right directions of the vehicle, and is configured such that by operating the shift lever 12 along the guide groove 38, a desired shift range can be shifted.

Further, on the back surface of the shift plate 36, as shown in FIGS. 3 and 4, a moderation plate 40 processed so that the movement locus of the moderation pin 32 is curved is attached.

The curved surface of the moderation plate 40 may be constructed so that a hollow sphere or a hollow cone is partially cut so that the movement locus of the moderation pin 32 is curved. Like the moderation plate 60 shown in FIG. 5, the moderation plate 62 shown in FIG. 6 may have different curvatures so that the X-axis direction is R and the Y-axis direction is R1. As described above, the Y-axis direction may be flat and the X-axis direction may be curved.

On the other hand, in the moderation plate 40, moderation grooves 42, which are arranged in parallel with the guide grooves 38 and are recessed in a hemispherical shape, are provided corresponding to each shift range position. This moderation groove 42
The head of the moderation pin 32, which is urged by the coil spring 30 by the operation of the shift lever 12, is inserted into the.

Further, in the drive "D" range, two moderation grooves 42 are formed side by side in the vehicle width direction. That is, when the shift lever 12 can be operated to the left or right, it is possible to determine by touching that the shift lever 12 is in the drive "D" range.

On the other hand, a housing 44 is arranged above the shift plate 36 to accommodate the shift plate 36 and is fixed to a floor portion in a vehicle compartment (not shown).

A guide groove 46 corresponding to the guide groove 38 of the shift plate 36 is formed in the ceiling portion 44A of the housing 44.
Is formed and the shift lever 12 penetrates. Next to the guide groove 46, "R", depending on the shift range,
Plate 48 with initial letters such as "N" and "D" printed
Is fitted.

Next, the operation of this embodiment will be described. When the shift lever 12 is operated back and forth and left and right along the guide groove 38, the moderation pin 32 moves in and out in a moderation groove 42 corresponding to a specific shift position corresponding to the operation of the shift lever 12 in a circular path. Therefore, the position of each shift range can be confirmed by the tactile sensation when the shift lever 12 is operated. By operating the shift lever 12 based on the drive “D” range, the positions of the “N” range and the “2” range can be determined.

[0020]

Since the present invention has the above-mentioned structure, the position of each shift range can be confirmed by the tactile sensation when the shift lever is operated.
