Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of unpleasant noises when a shift lever is shifted, by providing a first damper member which projects by a specified amount in the direction opposite to the direction of energization from the side to which the shift lever is energized and a second damper member which is provided at the side opposite to the direction of the projection and whose one side is in contact with a base plate. SOLUTION: If a shift lever 22 shifted to a P range is shifted to a D range, a ball 43 is moved into an engaging hole 24b and the shift lever 22 is stopped. If the shift lever 22 is pressed to a 3 range side in this state, the ball 43 is disengaged from the engaging hole 24b and is engaged with an engaging hole 24b of the 3 range side. On this case, since the shift lever 22 is hit on a first damper member 30 by energizing force of an energizing means 40 with momentum, the first damper member 30 is elastically deformed. A second damper member 32 is arranged opposite to the first damper member 30 of the upper part 24 of a base. Accordingly, the shock of the shift lever 22 is double absorbed by the first and second damper members 30, 32.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate-type shift lever device in which a shift lever shifts in a vehicle front-rear direction and a vehicle left-right direction, and in particular, it is possible to suppress the generation of unpleasant noise during shift operation of the shift lever. The present invention relates to the structure of a gate type shift lever device.

[0002]

2. Description of the Related Art A shift lever device for an automatic transmission includes a straight type shift lever device in which the shift lever can shift only in the vehicle front-rear direction, and a shift lever in the vehicle front-rear direction and the vehicle left-right direction (vehicle width direction). There is a shiftable gate type shift lever device. In the gate type shift lever device, since the shift lever swings back and forth and left and right,
Compared to a straight type shift lever device that swings only in a straight line, erroneous operation during shift operation is less likely to occur, but when shifting the shift lever, the shift lever hits the side surface of the detent groove formed on the base plate. There is a problem that a high-quality feeling is lost because a tapping sound is generated. Therefore, it is known that a cushion (cushioning material) is provided in order to reduce the hitting sound between the shift lever and the base plate.

5 and 6 show an example of prior art of a gate type shift lever device. Base plate 1
The shift lever 2 is swingably supported by the. A detent groove 3 is formed in the base plate 1. A cushioning material 4 is provided on the base plate 1. The cushioning material 4 projects inward from the side surface of the detent groove 3. The base plate 1 is provided with a plurality of bosses 6. The buffer material 4 is provided with a plurality of holes 4a. The cushioning member 4 is fixed to the base plate 1 with the boss 6 fitted in the hole 4a. During the shift operation of the shift lever 2, the shift lever 2 contacts the cushioning material 4, and the shift lever 2 contacts the side surface of the detent groove 3 in a state where the cushioning material 4 is elastically deformed in the compression direction.

An upper housing 7 serving as a design member is arranged above the base plate 1. A detent groove 8 forming a shift pattern is formed in the upper housing 7. During the shift operation, when the shift lever 2 elastically deforms in the compression direction by the shift lever 2 and the shift lever 2 hits the base plate 1, the shift lever 2 does not hit the side surface of the detent groove 8 of the upper housing 7. Has become. This is to prevent the upper housing 7 serving as a design member from being damaged or deformed. In the conventional device, it is not preferable to set a large gap a between the shift lever 2 and the upper housing 7 for design reasons. Therefore, the protrusion amount b of the cushioning material 4 from the side surface of the detent groove 3 is also too large. Cannot be set.

[0005]

However, the devices shown in FIGS. 5 and 6 also have the following problems. The shift lever 2 is constantly urged toward one side (three range side) of the detent groove 3 by the urging means 9, and it is necessary to operate the shift lever 2 with a force that overcomes this urging force when shifting is performed. There is. This is to prevent the shift lever 2 from unexpectedly moving while the vehicle is driving. Therefore, if you move the shift lever 2 to the vicinity of the D range located on the opposite side of the 3 range and release your hand,
The shift lever 2 vigorously hits the cushioning member 4 by the biasing force of the biasing means 9. In this case, as described above, the cushioning material 4
Since the protrusion amount b of the detent groove 3 with respect to the side surface is limited, the shock cannot be sufficiently absorbed only by the elastic deformation of the cushioning member 4, and an unpleasant sound is generated when the shift lever 2 hits the base plate 1. There was a case where the luxury was lost. An object of the present invention is to provide a gate type shift lever device capable of suppressing the generation of unpleasant noise during shift operation of the shift lever.

Item 2. A gate type shift lever device according to item 1.

In the above-mentioned device (1), the shift lever urged by the urging means comes into contact with the first cushioning member immediately before hitting the side surface of the detent groove in the upper portion of the base.
The shock is absorbed to some extent by the elastic deformation of the cushioning material. The impact not absorbed by the first cushioning material is transmitted to the second cushioning material via the upper part of the base and is absorbed by the elastic deformation of the second cushioning material. That is, the shock during the shift operation of the shift lever is absorbed in two stages by the two cushioning materials, and it is possible to suppress the generation of unpleasant noise.
You. In the above-mentioned device (2), since the first shock absorbing material and the second shock absorbing material are integrated with the base upper portion by the two-color molding, the first shock absorbing material is accurately applied to the detent groove in the base upper portion. It can be arranged, and the displacement of the first cushioning material with respect to the upper portion of the base does not occur when the shift lever hits the first cushioning material. Therefore, it becomes possible to obtain a predetermined impact absorbing ability for a long period of time.

b.

A biasing means 40 is provided at the lower end of the shift lever 22. The urging means 40 is composed of a slide member 41, a spring 42, and a ball 43. The slide member 41 is held by the lower end of the shift lever 22 so as to be slidable in the vertical direction. Ball 43
It is rotatably held on the top of the slide member 41.
The slide member 41 is biased upward by a spring 42. The ball 43 is pressed against the inclined surface 24 a of the upper base 24 by the urging force of the pulling 42. The shift lever 22 is biased toward the detent groove 25 side by the ball 43 being pressed by the inclined surface 24a. Engagement holes 24b into which a part of the balls 43 are engaged are formed on the D range and 3 range sides of the base upper portion 24, respectively. As shown in FIG. 3, when the shift lever 22 is shifted to the D range, a part of the ball 43 is engaged with the engagement hole 24b and the shift lever 22 is positioned in the D range. When the shift lever 22 is shifted to a range other than the D range, the biasing means 40 pushes the shift lever 22 against the side surface of the first cushioning member 30.

An upper cover 50 as a design member is attached to the top of the upper base 24. The shift lever 22 is inserted into the detent groove 51 of the upper cover 50. A slide cover 52 is arranged between the upper base 24 and the upper cover 50. Both ends of the slide cover 52 in the vehicle left-right direction are slidably held by the upper cover 50. Slide cover 5
The lower end surface of 2 is slidable with the first cushioning material 30. An auxiliary plate 53 is provided on the slide cover 52 so as to be movable in the vehicle left-right direction. The shift lever 22 is inserted through the slide cover 52 and the auxiliary plate 53. Slide cover 52 and auxiliary plate 53
Moves following the shift operation of the shift lever 22.

Next, the operation of the gate type shift lever device will be described. When the vehicle is parked or stopped, the shift lever 22 is shifted to the P range. When the vehicle starts, the shift lock is released by depressing the brake pedal, and the shift lever 22 can be shifted to another range. FIG. 1 shows the shift lever 22.
Shows a state in which is shifted to 3 ranges. In this state, the shift lever 22 is brought into close contact with the side surface 30a of the first cushioning material 30 by the biasing means 40. In this case, since the first cushioning material 30 projects from the side surface 25a on one side of the detent groove 25 by the distance T, the shift lever 22 moves to the first side.
The shock during the shift operation is reduced by hitting the cushioning material 30 of FIG.

When the shift lever 22 is shifted to the D range, the ball 43 enters the engagement hole 24b and the shift lever 22 comes to rest at the position shown in FIG. When the shift lever 22 is pushed toward the 3 range side in this state, the ball 43 and the engaging hole 24
The ball 43 is disengaged and the ball 43 is engaged with the engagement hole 2 on the 3 range side.
4b is engaged. In this case, the shift lever 22 vigorously hits the first cushioning material 30 by the biasing force of the biasing means 40, and the first cushioning material 30 elastically deforms. Here, since the second cushioning material 32 is arranged at a position facing the first cushioning material 30 on the upper base 24, the first cushioning material 3 is provided.
The force that compressively deforms 0 is transmitted to the second cushioning material 32 via the base upper portion 24, and the impact is also mitigated by the elastic deformation of the second cushioning material 32. That is, the first cushioning material 3
The shock of the shift lever 22 can be absorbed in two stages of 0 and the second cushioning material 32. Therefore, during the shift operation from the 3 range to the D range, the shift lever 22 does not hit the side surface 25a of the detent groove 25, and the generation of unpleasant noise is prevented.

The unpleasant noise when the shift lever 22 hits the detent groove 25 is not limited to the above example, and occurs when the shift lever 22 in FIG. 3 is moved from the left side to the right side by the biasing means 40. For example, when shifting to the R range, shifting the vehicle back, and then shifting to the D range and trying to move forward, the shift lever 22 is operated to be pulled toward you. At this time, the shift lever 22 hits the side surface side of the detent groove 25 by the urging means 40 in the N range which is the passing point, but the unpleasant sound caused by this impact is the same as the above case with the first buffer material 30 and the second buffer material. It is relaxed by the material 32.

Further, since the shock absorbing ability can be increased by the action of the second shock absorbing material 32, the first shock absorbing material 3
The protrusion amount T from the detent groove 25 of 0 can be set smaller than that of the conventional device. Therefore, the gap S between the side surface of the detent groove 51 of the upper cover 50 and the shift lever 22 can be made small, and the designability can be improved. Furthermore, since the first cushioning material 30 is molded in two colors with the base upper portion 24, and the first cushioning material 30 is in close contact with the side surface of the detent groove 25, the first cushioning material 30 is against the base upper portion 24. The protrusion amount T can be maintained without displacement. Therefore, it becomes possible to maintain the shock absorbing ability for a long period of time.

The shift operation of the shift lever 22 is performed not only in the left-right direction of the vehicle but also in the front-rear direction of the vehicle, for example, the shift operation of the range 3 to 2. In this case, similarly to the above, the portion 3 of the first cushioning material 30 located at the stepped portion of the detent groove 25 with which the shift lever 22 contacts.
0c and the portion 30d of the first cushioning material 30 located at the end in the vehicle front-rear direction are elastically deformed, and the impact due to the shift operation is mitigated. Therefore, the generation of unpleasant noise during the shift operation in the vehicle longitudinal direction is also prevented.

When the shift lever 22 is shifted in the vehicle longitudinal direction, the slide cover 52 slides on the upper surface of the first cushioning material 30 following the shift lever 22, and the first cushioning material 30 absorbs impact. Besides, since it has lubricity, the slide cover 52 slides well on the upper surface of the first buffer 30. Therefore, wear of the sliding surface is suppressed, and the operating force of the shift lever 22 can be reduced.

In a state where the shift lock is not released, when the shift lever 22 is attempted to shift from the P range to another range, the lower portion of the shift lever 22 contacts the stopper 23 and the shift operation is blocked. At this time, the shift lever 22 comes into contact with the other side surface 25b of the detent groove 25 of the base upper portion 24, but the base upper portion 24 is floatingly supported via the first buffer material 30 and the second buffer material 32. The frequency of the tapping sound (mainly film vibration) due to the abutment of the shift lever 22 can be suppressed, and the generation of a strange noise is prevented.
