Description

DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic transmission for a vehicle.
In the stop range, reverse range or running range
The shift device for selecting
Requires a braking operation when shifting from one range to another
And a shift lock device configured to
You. [0002] 2. Description of the Related Art As is well known, an automatic transmission of a vehicle includes a torque converter.
Power from the engine by a gear converter
The transmission is always transmitted to the
When the gear is set to one of the gears,
Driving like clutch operation in vehicles equipped with high speed gear
The vehicle travels without performing any special operations for So
For this reason, vehicles equipped with automatic transmissions
Or Neutral shift position is selected
Engine can be started only when it is running
doing. Therefore, in vehicles equipped with an automatic transmission,
After starting the engine, change the shift
Or "neutral" to "drive"
Perform a shift operation to change to a shift position for another drive.
It will be. Gear shifts associated with such shift operations
The mechanism is in the setting state of the shift speed such as the first forward speed and the reverse speed.
Can be switched, but at that point the driving force from the engine
Has already been transmitted through the torque converter,
It is possible to travel almost simultaneously with the shift operation. [0003] Conventionally, therefore, the vehicle is generally driven in a braking state.
Shift operation and then release the braking.
And run for the first time.
Various devices have been proposed to mechanically compensate for this. sand
In other words, the shift device of the automatic transmission shifts from the stopped state to the running state.
Shift operation for setting the reverse gear, etc.
Button operation and shift operation in addition to the normal shift operation.
Data that requires additional operations such as changing the operation direction of the bar
The detent machine usually has a detent mechanism.
A lock mechanism is additionally installed on the frame, and the shift lever is
The shift lever from that position
Movement is blocked by a lock mechanism, and the lock is braked
It is configured to be released with an operation. [0004] Conventionally, stearin is operated by key operation.
Shift from stop position to another shift with release of glock
Locking device that can be switched to the position
Japanese Patent Application Laid-Open No. 60-135352 has been proposed.
No., published in Japanese Unexamined Patent Publication No. To explain this briefly,
Bell crank that can be inserted into the tent pin
Is provided on the stop position side of the detent plate.
The bell crank has a detent pin
Elastic by spring in the direction that does not come out of the position
It is supported by. Operation by ignition key
Is slidable by a cable
The plate and cable connected to the bell crank
The detent pin is in the stop position
Prevents the bell crank from turning in the exit direction
It is configured to: I.e. ignition key
The plate becomes slidable by operating
As a result, the force to prevent the bell crank from rotating
Released and the detent pin moves from the stop position to another shift
Can be moved to the default position. That is, the shift lock is released
Is done. [0005] The problem described in the above-mentioned publication is as follows.
The conventional device that has been
Connect the rotating bell crank to the plate and cable.
To prevent rotation.
To prevent shifting of the gear, i.e., shift lock.
It has been achieved. Therefore, in the shift locked state,
Perform a shift operation without operating the ignition key.
Attempting to remove the detent pin from the stop shift position
Load in the direction in which the bell crank rotates.
Acts, and accordingly, a large tension acts on the cable.
Will do. Ie plates and cables etc.
Other than the load required for the lock operation
Since a load is applied to maintain the locked state,
The drive means must be strong enough to withstand the maximum load.
Therefore, in the above-described conventional configuration, the driving means has a high strength.
There was an inconvenience of increasing the size as much as possible. The present invention has been made in view of the above circumstances.
To provide a shift lock device that can be easily downsized.
The purpose is to do so. [0007] SUMMARY OF THE INVENTION The present invention provides the above-mentioned object.
Rotation of the automatic transmission to achieve
The hollow shaft that is made and rotates together with this hollow shaft
Detent pin and selectively engage this detent pin
The run position and the stop position to be formed are formed.
A detent plate and its axis line inside the hollow shaft
To be movable in the axial direction and to be moved in the axial direction.
Place the detent pins on each of the detent plate
Of an automatic transmission with a shaft
In the shaft lever lock device, the shaft member has an outer surface.
When an engaging recess recessed in the radial direction from the surface is formed
In addition, among the peripheral wall portions of the hollow shaft,In the recessOpposite clause
A through hole is formed at the place, and the center axis is further
Almost matchedAnd the shaft length is longer than the inner diameterWith through holes
A holding member is provided so as to protrude radially from the outer surface of the hollow shaft.
And fit almost tightly into these through holes.
Protruding along the radial direction of the shaft member into the recess,
And at least a first position engaged with the concave portion
And the second positionIs moved in the axial directionIs determined
A locking member is provided to operate the hollow shaft to a stop position.
Setting the locking member to the first position.
And, by performing the braking operation, the locking member is moved to the second position.
Set toSo that the locking member is reciprocated in the axial direction.
DriveMoving means is provided.
You. [0008] In the lock device according to the present invention, the rotation of the hollow shaft is performed.
The shift position of the automatic transmission is switched by
In this case, the detent action is integrated with the hollow shaft.
The rotating detent pin stops the detent plate.
By engaging the stop position or the running position
Done. Move the detent pin away from each position
The removal was provided movably in the axial direction inside the hollow shaft
This is performed by moving the shaft member in the axial direction. This
The shift lock, on the other hand, has a locking member
This is done by engaging. That is, the gear is shifted to the stop position.
If the braking operation is not performed in the
The material is hollow by the driving meansShaft and holding memberThrough hole
Through and into the recess of the shaft member to engage therewith. So
As a result, the detent pins are
Press the shaft member in the axial direction to release it from the
Even the locking member engaged with the shaft memberButThroughIn the holeBob
Closely fitted and unable to move in the axial direction of the hollow shaft
As a result, the shaft member and the detent pin are prevented from moving,
Foot lock is performed. In that case, the axial direction of the shaft member
The load is applied to the engagement or engagement between the recess and the through hole.
For stop membersMade as miso shear forceUse the locking member
Acts on the driving means for setting the first position and the second position.
There is no need to increase the size of driving means to increase strength
There is no. Note that the shift lock is released by performing a braking operation.
Driving means moves the locking member to the second position
And by pulling it out of the recess of the shaft member

In order to move forward, from the "parking" shift position
Shift operation to another shift position such as "Drive" is required
And At this time, the brake pedal 124 is not depressed.
When the vehicle is parked, the upper control

You. Therefore, depressing the brake pedal 124
The shift operation can be performed only when it is locked,
Shift from the “parking” shift position to another shift position
The brake pedal 124 must be depressed
It will be embedded. After the shift operation is completed
When the brake pedal 124 stops being depressed, the car starts.
Can be advanced. The depression of the brake pedal 124 is stopped.
Then, the slider 106 connects the push-pull cable 122

The lock pin 108 is located outside the upper control shaft 24.
It comes into contact with the periphery and shifts to the “parking” shift position.
As long as the upper control shaft 24 is not
Without blocking the rotation, the car as described above
