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 shifting a transmission of a vehicle.

[0002]

2. Description of the Related Art Some shift lever devices for shifting an automatic transmission of a vehicle are provided with a shift lock mechanism that enables the shifting operation only under specific conditions.
In this shift lock mechanism, it is known that the grooved pin provided on the shift lever is restrained by the shift lock plate.

For example, when the shift lever is selected to the P shift range, the grooved pin engages with the shift lock plate and the movement of the shift lock plate is blocked by the plate stopper, so that the shift operation of the shift lever is blocked. Further, when the brake operation is performed, the solenoid is energized to move the plate stopper and the shift lock plate can be moved, so that the shift lever can be shifted (so-called P range shift lock). Furthermore, when the shift lever is selected to the N shift range, the shift operation of the shift lever to the R shift range is blocked unless the speed reaches a predetermined vehicle speed or lower, and the solenoid is energized when the speed reaches a predetermined vehicle speed or lower. The shift lever can be operated to shift to the R shift range (so-called R inhibit).
There is also one.

By the way, in the shift lever device having such a shift lock mechanism, as described above, in a specific shift range, the shift lock state can be set under each condition, but each shift lock mechanism is individually provided. Since they were provided independently, in other words, they were configured so that they could be locked by independent shift lock plates, plate stoppers, or solenoids. Since the shift lock plate and the solenoid have to be provided, the number of parts increases and the structure becomes complicated.

Above all, there is no L range shift lock mechanism for preventing the shift operation to the L shift range when the vehicle is traveling at a high speed (D shift range or 2 shift range), and a countermeasure therefor is desired. Was there. In this case, the operation timing of the solenoid in the existing P range shift lock mechanism and the R inhibit mechanism is different from the operation timing in the case of preventing such a shift operation to the L range, so that the shift lock plate of each mechanism or The solenoid cannot be used as it is to construct an L range shift lock mechanism.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a shift lever device 10 according to the present invention.
FIG. 2 shows a plan view of a main part of FIG. 2, and FIG. 2 shows a plan view of a correspondence relationship between main components used in the shift lever device 10. Further, FIG. 3 shows a cross-sectional view of a main part of the shift lever device 10 taken along line 3-3 of FIG.
FIG. 4 is a perspective view showing the configuration of the main part of the shift lever device 10.

The shift lever device 10 includes a lever 12 connected to an automatic transmission via a cable or the like.
A grooved pin is provided at the lower end of the shaft 12 in the axial direction, and a detent plate is further arranged (all are not shown). By operating the shift lever knob button and pushing down the grooved pin, the grooved pin can get over the unevenness of the detent plate, which allows the lever 12 to rotate around the axis (movable in the vehicle longitudinal direction). ,
The configuration is such that the shift mode (range) of the automatic transmission can be selected. This structure is similar to that of a general shift lever device.

A lock plate 14 is integrally attached to the lever 12 at a substantially intermediate portion in the axial direction. The lock plate 14 is plate-shaped, and a connecting hole 16 is formed in one side portion thereof. The lever 12 penetrates the connecting hole 16 and is integrally attached in a state orthogonal to the axis of the lever 12. Therefore, the lock plate 14 is always in the lever 12
Move with.

A stopper hole 18 is formed in the lock plate 14. As shown in detail in FIG. 2, the stopper hole 1
The lever 8 is formed continuously in a slender shape along the moving direction of the lever 12 (direction of arrow A in FIGS. 1 and 2).
2 shift positions, that is, “P”, “R”, “N”,
It is associated with each shift position of "D", "2", and "L". The stopper hole 18 is located on the side of the connecting hole 16 and is located in the first slide portion 2 along the moving direction of the lever 12.
0, and a second slide portion 22 which is located on the side of the first slide portion 20 and which is also along the moving direction of the lever 12. (In other words, the first slide portion 20 and the second slide portion 22 are formed in two lines along the moving direction of the lever 12 in the direction orthogonal to this moving direction).

In the portion of the first slide portion 20 corresponding to the "R" shift position, a convex portion 24 is formed so as to project inward, and the side wall portion 26 and the side wall portion 28 are respectively ". This corresponds to the "P" shift position and the "N" shift position.

On the other hand, of the second slide portion 22, "L"
The convex portion 30 is formed so as to project inward at a portion corresponding to the shift position of, and the side wall portion 32 thereof corresponds to the shift position of "2". In addition, the second slide portion 22
Of these, a wedge-shaped convex portion 34 is similarly formed to project inward at a portion corresponding to the “N” shift position,
The side wall portion 36 corresponds to the "D" shift position, and the inclined portion 38 corresponds to the "N" shift position.

The side wall portion 26, the side wall portion 28, the side wall portion 32, the side wall portion 36 and the inclined portion 38 can be engaged with a link 40 which will be described in detail later.

In the stopper hole 18 of the lock plate 14, a link 40 as a lock member is arranged so as to be inserted. As shown in FIG. 4, the link 40 has a shaft 42.
Is rotatably supported by the stopper hole 18 (first slide portion 20 or second slide portion 2).
2) It is inside. Therefore, the link 40 is
By rotating around the shaft 42, between the first slide portion 20 and the second slide portion 22 of the stopper hole 18 (see FIG.
3) and can be engaged with the side wall portion 26, the side wall portion 28, the side wall portion 32, and the side wall portion 36 of the stopper hole 18 at a specific shift position. The link 40 includes the side wall portion 26, the side wall portion 28,
In a state in which the side wall portion 32 and the side wall portion 36 are engaged, the lock plate 14 is prevented from moving (moving in a direction facing the link 40) at the specific shift position.

A solenoid 44 is provided at the lower end of the link 40.
Plunger 46 is connected. The solenoid 44 attracts the plunger 46 when energized,
When not energized, the plunger 46 is pulled out by the urging force of the internally provided return spring. When the solenoid 44 is not energized, the link 40 has the stopper hole 1
It is set so as to be positioned on the first slide portion 20 of No. 8. When the solenoid 44 is energized and excited, by pulling the plunger 46 against the urging force of the return spring, the link 40 rotates around the shaft 42 and the second slide portion 20 of the stopper hole 18 slides. It is a structure which moves to the part 22.

The solenoid 44 is adapted to be energized and deenergized by electrical control according to the shift position of the lever 12 and the running state of the vehicle. Specifically, when the lever 12 is selected to the "P" shift position, it is normally de-energized, and energized and excited only when the brake is operated. Further, when the lever 12 is selected to the "N" shift position, it is de-energized when the vehicle is running at a medium speed or higher, and energized and excited only when the vehicle is running at a low speed or stopped. . Further, the lever 12 has "D", "2", and "L".
When selected for each shift position of, when the vehicle is running at a medium speed or lower or stopped, it is de-energized,
The energization is excited only when the lever 12 is selected to each of the shift positions "D" and "2" and the vehicle is in the high-speed traveling state.

When the lever 12 is selected to each of the "D", "2", and "L" shift positions, energization is excited even when the vehicle is running at a low speed or stopped. Instead of changing the shift position to "N", energization and excitation is performed only when the shift position is "N". In other words, the lever 12 is "N".
When the shift position of 1 is changed to each of the shift positions of “D”, “2”, and “L”, the energization excitation is canceled even if the vehicle is in the low speed running state or in the stopped state. This is controlled by a switch or the like for the N "shift position.

Next, the operation of the shift lever device 10 having the above-described structure will be sequentially described according to the shift position of the lever 12 and the traveling state of the vehicle.

As shown in FIG. 5, when the lever 12 is selected to the "P" shift position (when the vehicle is stopped), the solenoid 44 is in the non-energized state, and therefore the link 40 is used.
Is located on the first slide portion 20 of the stopper hole 18 and faces the side wall portion 26. Therefore, a shift lock state (so-called P range shift lock) is obtained in which the movement of the lock plate 14, that is, the movement of the lever 12 from the "P" shift position to another shift position is prevented. Here, when the brake is operated, the solenoid 44 is energized and excited, whereby the link 40 moves from the first slide portion 20 of the stopper hole 18 to the second slide portion 22 and is separated from the side wall portion 26. Therefore, the lock plate 14 can be moved, that is, the lever 12 can be moved from the “P” shift position to the “R” shift position (P range shift lock is released).

When the shift lock at the "P" shift position is released and the lever 12 is selected to the "R" shift position (the state shown in FIG. 6), the shift lock is not applicable and the lock plate 14 is not present. Can be moved.

On the other hand, as shown in FIG. 7, when the lever 12 is selected to the "N" shift position, the solenoid 44 is energized and excited when the vehicle is in the stopped state or in the low speed traveling state, whereby the link is generated. 40 is the stopper hole 18
It is located on the second slide portion 22 and contacts the inclined portion 38. Therefore, it is possible to move the lock plate 14, that is, move from the “N” shift position to the “R” shift position, and further, by moving the link 40 along the inclined portion 38, It is possible to move from the shift position to the "D" shift position. On the other hand, when the lever 12 is selected to the “N” shift position, the solenoid 44 is de-energized when the vehicle is running at a medium speed or higher, and therefore the link 40 has the first slide portion of the stopper hole 18. It is located at 20 and faces the side wall portion 28.
Therefore, the shift lock state in which the movement of the lock plate 14, that is, the movement from the “N” shift position to the “R” shift position is prevented (so-called R inhibit)
Becomes When the vehicle is running at a medium speed or lower or is stopped, the solenoid 44 is energized and excited to release the shift lock.

Also, as shown in FIG. 8, when the lever 12 is selected to the "D" shift position, the solenoid 44 is in the non-energized state if the vehicle is running at a medium speed or lower or is in a stopped state. Therefore, the link 40 is positioned on the first slide portion 20 of the stopper hole 18, and the lock plate 14 can be moved, that is, from the “D” shift position to another shift position. On the other hand, when the vehicle is traveling at a high speed when the lever 12 is selected to the “D” shift position, the solenoid 44 is energized and excited, which causes the link 40 to move the link 40 to the first slide portion 20 of the stopper hole 18.
To the second slide portion 22 and faces the side wall portion 36. Therefore, the lock plate 14 can move only between the "D" shift position and the "2" shift position, and the movement from the "D" shift position to the "N" shift position is prevented. The shift is locked.

Further, as shown in FIG. 9, when the lever 12 is selected to the shift position "2", the solenoid is operated if the vehicle is running at a medium speed or lower or is stopped, as described above. Since 44 is de-energized, the link 40 is positioned on the first slide portion 20 of the stopper hole 18 and the lock plate 14 can be moved, that is, the shift position of "2" can be moved to another shift position. Become. On the other hand, when the vehicle is traveling at a high speed when the lever 12 is selected to the shift position of "2", the solenoid 44 is energized and excited, whereby the link 40 is positioned at the second slide portion 22 of the stopper hole 18. It is in a state of facing the side wall portion 32. Therefore, the lock plate 14 can move only between the "2" shift position and the "D" shift position, and the movement from the "2" shift position to the "L" shift position is prevented. The shift lock state is set, and the engine is prevented from over-rotating.

As described above, in the shift lever device 10,
"P", "R", "N", "D", "2", and "L"
The solenoid 44 operates according to the vehicle speed set individually in a specific shift position such as. Solenoid 4
4 operates, the link 40 is moved in the stopper hole 18, and the stopper hole 1 set at each specific shift position is set.
The inner peripheral wall of 8 (side wall portion 26, side wall portion 28, side wall portion 32, side wall portion 36) can be engaged. Therefore, in this state, the lock plate 14 at the specific shift position is
That is, the movement of the lever 12 is blocked, and the shift lock state is established.

As described above, the solenoid 44 operates in accordance with the vehicle speed set individually at a specific shift position, whereby the movement of the lock plate 14, that is, the lever 12 can be prevented. With a simple structure, the shift lock state can be obtained under a plurality of different conditions.
