[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lock device used in a shift lever device for shifting a transmission and restraining a shift operation of the shift lever at a specific shift position. The present invention relates to a so-called gate (zigzag operation) type shift lever device shift lock device configured to perform a shift operation in the vehicle left-right direction to select a shift position.

[0002]

2. Description of the Related Art Recently, automatic transmissions for vehicles have been made into a multi-speed shift specification, and there is a tendency that a large number of shift ranges are set. Therefore, there is a demand for a shift lever device capable of selecting a plurality of set shift ranges.

A shift lever device for shifting an automatic transmission of a vehicle generally has a structure for shifting the automatic transmission by shifting the shift lever in the longitudinal direction of the vehicle. In such a conventional shift lever device, there is a limit in arrangement space (shift lever operation movement range) and operability when applied to an automatic transmission in which a large number of shift ranges are set. Therefore, a so-called gate (zigzag operation) type shift lever device has been proposed which is configured to shift the shift lever not only in the vehicle front-rear direction but also in the vehicle left-right direction to select a shift position.

In this type of gate type shift lever device, even when applied to an automatic transmission in which a plurality of shift ranges are set, the plurality of shifts are carried out in a compact space (shift lever operation movement range). The range can be selected and operated, and an increase in the set shift range can be dealt with.

By the way, in the gate type shift lever device as described above, the operation direction of the shift lever is simply set to the vehicle front-rear direction and the left-right direction (so-called zigzag). For example, the shift lever has an N shift range. The shift operation to the R shift range can be performed by the two operations of moving the shift lever in the left-right direction of the vehicle and then moving it in the front direction of the vehicle when the switch is selected. However, in such a shift lever device, the above-mentioned movement may be performed only by applying a load diagonally forward to the shift lever, and the R shift range may be entered by one operation. Therefore, a shift lock mechanism that enables the shift operation only under a specific condition is required, and the shift operation from the N shift range to the R shift range as described above needs to be limited by some method.

In this case, as a shift lock device which allows the shift lever to operate only under a specific condition such as when the brake is operated, a solenoid plate for arranging a stopper plate corresponding to the shift lever and for moving the stopper plate is provided. There is known a structure provided with.

In this main shift lock device, when the shift lever is selected in the P shift range, the stopper plate is brought into a state in which the stopper plate can be engaged with the shift lever located in the P shift range. A shift to a shift range other than the P shift range is blocked, and a shift lock state is set. On the other hand, in this case, when the brake is operated, the solenoid operates and the stopper P
The shift lever located in the shift range is moved to the released position. As a result, the shift lever can be moved to a shift range other than the P shift range, and the shift lock is released.

When the shift lever is selected from the N shift range to the L shift range, the solenoid operates at a predetermined vehicle speed set according to the N shift range to the L shift range, and the stopper operates. It is moved to a position where it can be engaged with the shift lever located in the N shift range. As a result, the shift lever is prevented from moving to the R shift range, and the shift lock state is established.

[0009]

By the way, such a conventional shift lock device of a shift lever device for a transmission is composed of a large number of parts, and the parts are laid out at different positions on the vehicle body side and rotated. It is configured to be connected via a support shaft or the like. For this reason, the assembly and accuracy control are not easy, and the applicability to different vehicle types is low, which is a cause of high cost.

In consideration of the above facts, the present invention facilitates the assemblability and the accuracy control, expands the range of application to different vehicle types, and can reduce the cost, and the shift lock of the transmission shift lever device. The purpose is to obtain a device.

[0011]

According to a first aspect of the present invention, there is provided a shift lock device for a shift lever device for a transmission, comprising:
By shifting a shift lever connected to a transmission having shift ranges of R shift range, N shift range, and N shift range in the front-rear direction and the left-right direction, one of the shift ranges is selected and the shift is performed. Shifts the machine and simultaneously shifts the P shift range of the shift lever.
And the directions of the selective movement to the N shift range are parallel to each other.
A shift lock device used in the shift lever device set in the same left and right direction to restrain the shift operation of the shift lever at a specific shift position, the shift lock device being provided in the shift lever and moving together with the shift lever. , Movable relative to the shift lever along the same direction as the left-right movement direction of the shift lever, and engageable with a member on the vehicle body side when the shift lever is selected in the P shift range and the N shift range. When the shift lever is selected between the P shift range and the N shift range and the relative movement with the shift lever is blocked, the shift lever is moved in the left-right direction by engaging with the member on the vehicle body side. It is possible to engage the stopper and the stopper that is always biased in the direction to engage the member on the vehicle body side while blocking A solenoid provided on the shift lever, the solenoid blocking the relative movement of the stopper with the shift lever in the engaged state and releasing the relative movement blocking of the stopper by electrically operating, and the solenoid provided on the shift lever. , A P position detection switch for detecting the movement position of the shift lever that has reached the P shift range, and the stopper, the solenoid, and the P position detection switch are attached to a bracket attached to the shift lever to form a single unit. The feature is that it is one unit. A shift gear for a transmission according to the invention of claim 2

[0012]

In the shift lock device of the shift lever device for a transmission having the above-mentioned structure, the stopper, solenoid, and P position detection switch, which form the lock mechanism, are assembled into a bracket attached to the shift lever to form a single unit. Since it is a unit, in other words, since the shift lock device, which is a single unit, is attached to the shift lever, the assembling property is improved and the accuracy control is facilitated.
Further, even in different vehicle types, it is possible to standardize parts, standardize them, or automate assembly, and expand the range of application.

1 is a perspective view showing a shift lock device 30 according to a first embodiment of the present invention and a main part of a shift lever device 10 to which the shift lock device 30 is applied. Further, FIG. 2 shows a front view of the shift lock device 30, and FIG. 3 shows a plan view of the shift lock device 30. In each drawing, the arrow A direction is the vehicle front-rear direction and the arrow B direction is the vehicle left-right direction.

In the shift lever device 10 to which the shift lock device 30 is applied, the shift lever 12 has the block 14
Is integrally projected upward from the upper end of the. The lower end of the block 14 is rotatably supported by a shaft (not shown) in the vehicle front-rear direction and the vehicle left-right direction.
It is connected to an automatic transmission (not shown) via a rod or the like. Further, the shift lever 12 has a so-called gate-type structure that can be shifted forward and backward and left and right (so-called zigzag) along the guide hole 22 (see FIG. 4).

An arm 16 is extended from the block 14, and a detent pin 24 and a spring 26 are accommodated in the arm 16 so that the detent pin 24 is biased upward. It is protruding. Moderation pin 24
Enter into the moderation groove formed on the back surface side of the moderation plate 28. This moderation plate 28 (moderation groove) is at the shift position of the shift lever 12, that is, “P”,
Associated with each shift range such as "R", "N", etc., it is bent continuously in an uneven shape.
As 6 moves over, shift lever 12 is moved with moderation.

A shift lock device 30 is attached to the block 14 of the shift lever 12 having the above structure.

The shift lock device 30 includes a bracket 32.
Is equipped with. The bracket 32 is plate-shaped, and the block 14
It is fixed to. A stopper 34 is arranged on the bracket 32.

The stopper 34 is arranged along the lateral movement direction of the shift lever 12 (direction of arrow B).
Is provided so as to be movable relative to each other, and is movable between a state in which the tip portion projects outward from the bracket 32 and a state in which it is retracted inward. The stopper 34 has
A compression spring 36 is attached, and the tip of the compression spring 36 is always biased in a direction projecting outward from the bracket 32. The stopper 34 selects the "P" shift range (the position of the guide hole 22) and the "N" shift range (the position of the guide hole 22) by the shift lever 12 in a state where the tip portion thereof projects outward from the bracket 32. When it is moved, it can be engaged with a member on the vehicle body side (not shown), and by engaging it, the movement of the shift lever 12 in the left-right direction (direction of arrow B) is restricted.

A solenoid 44 is provided on the side of the stopper 34.
Are arranged via the connecting link 43. The solenoid 44 is fixed to the bracket 32 and attracts the plunger 46 when energized. When the solenoid is not energized, the plunger 46 is pulled out by the urging force of the return spring installed inside. When the solenoid 44 is excited, the connecting link 43 is moved by pulling the plunger 46 against the urging force of the return spring. The dimensions of each part are set so that the tip of the connecting link 43 is engaged with the stopper 34 when the solenoid 44 is not energized.

Therefore, when the solenoid 44 is not energized, the distal end portion of the connecting link 43 engages with the stopper 34 and the stopper 34 moves relative to the shift lever 12 (the distal end portion retracts inward of the bracket 32). Arrested,
On the other hand, when the solenoid 44 is energized and the plunger 46 is attracted to move the connecting link 43, the tip end of the connecting link 43 is separated from the stopper 34 and the engagement is released, so that the stopper 34 engages with the shift lever 12. This is a configuration that enables relative movement.

The solenoid 44 is adapted to be energized and deenergized by electrical control according to the running state of the vehicle, and specifically, the shift lever 12 is released.
When is selected to the "P" shift range, it is operated by the brake operation, and when the shift lever 12 comes out of the "P" shift range, it is stopped (de-energized), and the shift lever 12 is switched to the "N" shift range. When selected, it is activated when the vehicle speed falls below a set predetermined vehicle speed.

A P position detection switch 48 is arranged on the bracket 32 on the side of the solenoid 44. The pressing portion 54 of the P position detection switch 48 is configured to be pressed by a member (not shown) on the vehicle body side to operate when the shift lever 12 is located in the "P" shift range (position of the guide hole 22).

Further, the shift lock device 30 is provided with a forced release mechanism. That is, immediately above the connection link 43 to which the plunger 46 of the solenoid 44 is connected,
A release arm 58 is attached so as to be movable up and down. An inclined surface 60 is formed at the tip of the release arm 58. Therefore, when the release arm 58 is pressed by a release button or the like (not shown), the inclined surface 60 presses the connection link 43 and the connection link 43 (the plunger 4
6) is a configuration in which the solenoid 44 is forcibly moved against the biasing force of the return spring.

As described above, the stopper 34, the solenoid 44, the P position detection switch 48, etc. are assembled to the bracket 32, and the shift lock device 30 together with the bracket 32 is a single unit.
The shift lock device 30, which is a single unit, is integrally assembled to the shift lever 12.

Next, the operation of this embodiment will be described. In the shift lock device 30 (shift lever device 10) having the above configuration, when the shift lever 12 is operated back and forth and left and right along the guide hole, the moderation pin 24 is guided by the concavity and convexity of the moderation groove of the moderation plate 28, and the shift lever is moved. It moves to a specific shift position according to the operation of 12 with a feeling of moderation.

Further, here, in a specific shift range or in a traveling state of the vehicle, the solenoid 44 of the shift lock device 30 operates, and the movement of the shift lever 12 is restricted.

For example, when the shift lever 12 is selected in the "P" shift range, this is detected by the P position detection switch 48, and the solenoid 44 is de-energized.

When the solenoid 44 is not energized, the plunger 46 is pulled out. As a result, the distal end portion of the connecting link 43 engages with the stopper 34, and the relative movement of the stopper 34 with the shift lever 12 (in the direction of arrow B) is blocked. At this point, the stopper 3
Reference numeral 4 is an engagement with a member on the vehicle body side. Therefore, even if an attempt is made to move the shift lever 12 in the left-right direction (from the position of the guide hole 22 to the position), this is prevented, and the shift lever 12 moves to a shift range other than the "P" shift range ("R"). The shift lock state (movement in the shift range direction) is blocked (so-called P range shift lock).

On the other hand, when the ignition switch of the vehicle is turned on and the brake is depressed after the shift lever 12 is selected to the shift range of "P" and the shift lock state is set, the solenoid 44 is energized. As a result, the plunger 4 is resisted against the biasing force of the return spring.
6 is pulled in, the connecting link 43 is moved, the tip end of the connecting link 43 is separated from the stopper 34, and the engagement is released, so that the stopper 34 can move relative to the shift lever 12. Therefore, when the shift lever 12 is operated in the left-right direction (from the position of the guide hole 22 to the position), the stopper 34 moves relatively to the shift lever 12 against the urging force of the compression spring 36, and the tip portion of the bracket 32 moves. When pushed inward, the shift lever 12 can be moved. That is, the shift lock release state in which the shift lever 12 can be moved in the “R” shift range direction is thereby set, and the shift lever 12 can perform the shift operation.

When the shift lever 12 comes out of the "P" shift range, this is detected by the P position detection switch 48.

When the shift lever 12 is selected to the "N" shift range while the vehicle is running and the predetermined vehicle speed set in accordance with the "N" shift range is reached, the energization of the solenoid 44 is stopped. It Therefore, the plunger 46 is pulled out and the connecting link 43 is moved to the original position again. When the connecting link 43 is moved to the original position,
The tip end of the connecting link 43 is again engaged with the stopper 34, and the relative movement of the stopper 34 with the shift lever 12 (the tip end is retracted inward of the bracket 32) is prevented. For this reason, the shift lever 12 cannot move from position to position of the guide hole 22, and thus the shift lock state in which the shift lever 12 is prevented from moving from the “N” shift range to the “R” shift range ( So-called R
Inhibit).

Further, when the vehicle speed falls below a predetermined traveling speed, the solenoid 44 is energized again. As a result, the plunger 46 is pulled in against the urging force of the return spring, the connecting link 43 is moved, and the connecting link 43 is moved.
The distal end of is separated from the stopper 34 and the engagement is released,
The stopper 34 can move relative to the shift lever 12. Therefore, the left and right direction of the shift lever 12 (arrow B
(Direction) (movement from position of the guide hole 22 to position) is possible. Therefore, the shift lever 12 can be moved from the "N" shift range to the "R" shift range, and the shift lock (R inhibit state).
Is released.

As described above, in the shift lock device 30,
The shift lock of the shift lever 12 at each of the "P" and "N" shift positions is operated in response to the brake operation and the set vehicle speed, and the solenoid 44 is moved to move the shift lever 12 relative to each other. Since it is performed by a simple configuration using the stopper 34 that prevents the above, the mechanism is simple and a small arrangement space is required, and the cost can be significantly reduced. Further, since the solenoid 44 is activated and shift-locked according to the vehicle speed set at each shift position, the operation timing of the solenoid 44 can be easily set, and the shift-locked state can be reliably achieved. The scope of application will be greatly expanded. Further, the shift lever 12 that is operated to the front, back, left, and right can be moved to a desired shift range without any other special operation (for example, pushing operation of the shift lever 12), and the operability of the shift lever 12 is improved. Will not hurt.

Further, in the shift lock device 30, the solenoid 44 is not energized and excited when the engine is not operating or when the connection with the power source is cut off during vehicle maintenance work or the like. The plunger 46 is pulled out by the urging force, the connecting link 43 engages with the stopper 34, and the stopper 34 moves relative to the shift lever 12 (the tip portion is the bracket 32).
Of the shift lever 12
Is in a shift lock state in which shift operation cannot be performed. In such a case or in a situation where the solenoid 44 does not operate even when the solenoid 44 is energized (so-called off-failure), the shift lock release state is forced by operating the forced release mechanism. Can be That is, when the release arm 58 is pressed by the release button or the like, the inclined surface 60 presses the connecting link 43 and the connecting link 43 (plunger 46) is forcibly moved against the biasing force of the return spring of the solenoid 44. It As a result, the engagement between the connecting link 43 and the stopper 34 is released, and the stopper 34 can be moved relatively, and the shift lever 12 is moved from the “P” shift range or the “N” shift range to the “R” shift range. be able to.

Further, in the shift lock device 30, the stopper 34 that locks the shift lever 12 is configured to prevent the shift lever 12 from moving in the vehicle left-right direction, that is, in the direction orthogonal to the operating direction of the solenoid 44. Therefore, for example, even if the shift lever 12 is forcibly operated and moved in the shift lock state, the operating force does not act on the solenoid 44, and the durability of the solenoid 44 is significantly improved.

Further, here, in the shift lock device 30, the stopper 34 and the solenoid 4 which constitute a lock mechanism.
4 and each component of the P position detection switch 48 are integrally assembled to the bracket 32 to form a single unit. In other words, the shift lock device 30 formed as a single unit is the shift lever. Since the shift lock device 30 is mounted on the shift lever 12, the assembling property when the shift lock device 30 is applied to the shift lever 12 is improved and the accuracy control is facilitated. Further, even in different vehicle types, it is possible to standardize parts, standardize them, or automate assembly, and expand the range of application. Further, the cover of the solenoid 44 and the wiring code of the P position detection switch 48 are unnecessary (can be abolished), and the wiring process is also unnecessary. Therefore, the cost can be reduced.

[0037]

As described above, the shift lock device of the shift lever device for a transmission according to the present invention facilitates the assembling property and the accuracy control, expands the range of application to different vehicle types, and reduces the cost. It has an excellent effect that it can be achieved.
