BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever inhibiting device for an automatic transmission, and more particularly, to an automatic shifting device having a reverse inhibit function of a shift lever for preventing a shift lever from being accidentally brought into a reverse position during running. The present invention relates to an inhibit device for a shift lever of a machine.

[0002]

2. Description of the Related Art Conventionally, a vehicle equipped with an automatic transmission (hereinafter referred to as an A / T vehicle) is provided with a floor-type shift lever, and the shift lever designates a shift position of the automatic transmission. . Fig. 6 shows the driver's seat of the A / T car.
Shown in

As shown in FIG. 6 , a brake pedal 2 is provided at a driver's seat 1 of an A / T vehicle in front of a foot of the driver's seat 1. The driver's seat 1 is provided with a shift lever housing 3 at the front left of the driver's seat 1. A shift pattern hole 4 is formed in the shift lever housing 3, and a shift lever 5 is inserted through the shift pattern hole 4 so as to be swingable in the front-rear direction and the left-right direction.

As shown in FIG. 7 , a plurality of steps are formed on the inner surface of the shift pattern hole 4, and when the shift lever 5 is moved, the shift lever 5 is moved right and left along the inner surface of the shift pattern hole 4. Move in the front-back direction while moving in the direction. In the shift pattern hole 4, a shift position corresponding to an automatic transmission (not shown) of the A / T vehicle is set at a predetermined position.

[0005] The shift position is provided with a parking position PP where the drive wheels are mechanically locked, a neutral position PN where the speed change element does not act, and a reverse position PR for moving the vehicle backward. The automatic transmission is a three-speed forward transmission, and its shift position is a drive position PD for performing forward automatic shifting of all transmissions, and fixed positions P1, P2, and P3 fixed to each of the three forward speeds. Is provided.
The function of the shift position can be selected by moving the shift lever 5 in the front-rear direction while swinging the shift lever 5 in the left-right direction and moving the shift lever 5 to each shift position. That is, the shift pattern hole 4 is a passage for the shift lever 5 to move to each shift position.

The operation of the shift lever 5 will be described. For example, when the shift lever 5 is moved out of the parking position PP, the shift lever 5 is first moved rightward until the shift lever 5 becomes a position where it can be moved backward. Next, the shift lever 5 is moved backward (downward in the figure) along the inner surface of the shift pattern hole 4 until the shift lever 5 comes into contact with the step portion 4a. Then, the shift lever 5 is moved to the left to make contact with the inner surface of the shift pattern hole 4. With this operation, the shift lever 5 is moved to the parking position P.
P can escape.

When the shift lever 5 is moved to the neutral position P
When the shift lever 5 is moved from the position N to the reverse position PR, the shift lever 5 is first moved rightward until the shift lever 5 can move forward. Next, the shift lever 5 is moved forward (upward in the figure) until it comes into contact with the step 4b. By this operation, the shift lever 5 can be moved from the neutral position PN to the reverse position PR.

Further, as shown in FIG. 7 , the shift lever housing 3 is provided with an inhibit lock mechanism 10. The inhibit lock mechanism 10 includes the shift lever 5
Is inadvertently shifted from the neutral position PN to the reverse position PR.
To prevent entry. That is, if the shift lever 5 at any one of the drive position PD or the fixed positions P1, P2, and P3 enters the reverse position PR due to an erroneous operation while the A / T vehicle is traveling forward, a large shock occurs in the vehicle. . Therefore, the shift lever 5 cannot be moved to the reverse position PR unless conditions such as stopping of the vehicle are satisfied.

The structure of the inhibit lock mechanism 10 will be described. The inhibit lock mechanism 10 includes first and second lock pieces 11 and 12, a link 13, and a solenoid 14. First lock piece 11
Has one end pivotally mounted on the fixed shaft 15 and the other end disposed in the shift pattern hole 4. The second lock piece 12 is rotatably supported by a fixed shaft 16, one end of which is disposed in the shift pattern hole 4, and the other end of which is the link 1.
3 is connected to the first lock piece 11. Also,
The first lock piece 11 is rotatably mounted on a tip of a plunger 14 a of the solenoid 14.

The solenoid 14 is connected to a control circuit (not shown), and the control circuit controls the solenoid 14 to an excited state (ON) and a non-excited state (OFF) based on conditions such as stopping the vehicle. I have. And solenoid 1
4 is controlled to be off, the plunger 14a is protruded by the pressing spring 14b, and the first and second lock pieces 1 are moved.
Reference numerals 1 and 12 are arranged in the shift pattern hole 4 and close the shift pattern hole 4, that is, the passage of the shift lever 5.

Then, the shift lever 5 at the parking position PP is engaged with the first lock piece 11, so that the left and right swing thereof is restricted. Therefore, the shift lever 5 cannot escape from the parking position PP. The shift lever 5 at the neutral position PN is in the second position.
And the rocking in the left-right direction is restricted. Therefore, the shift lever 5 is moved to the reverse position PR.
Can not be moved.

On the other hand, when the solenoid 14 is controlled to be turned on, the plunger 14a is retracted to retract the first and second lock pieces 11, 12 from the shift pattern hole 4. Then, the shift lever 5 at the parking position PP does not engage with the first lock piece 11, so that the shift lever 5 can escape from the parking position PP. Further, the shift lever 5 at the neutral position PN does not engage with the second lock piece 12, so that the reverse position PR
Can be moved to.

When the solenoid 14 is off, the shift lever 5 may be in the reverse position PR. At this time, the first lock piece 11 is moved forward by the shift lever 5 against the elastic force of the pressing spring 14b, and is further moved leftward to move to the parking position PP. Further, the second lock piece 12 can be moved rearward by the shift lever 5 against the elastic force of the pressing spring 14b, and further moved to the left to be moved to the neutral position PN.

[0014]

By the way, both lock pieces 11 and 12 constituting the inhibit lock mechanism 10 will be described.
In addition, the link 13 may be difficult to rotate due to dimensional accuracy, the amount of grease applied to the rotating portion, or the like. Since the link lock pieces 11, 12 and the link 13 which are hard to rotate are forcibly rotated, the load on the solenoid 14 is increased and the solenoid 14 cannot be operated stably. is there.

The solenoid 14 is turned on when the shift lever 5 is moved from the parking position PP or the neutral position PN to the reverse position PR, and the plunger 14a is moved. On the other hand, also when the plunger 14a is moved from the reverse position PR to the parking position PP or the neutral position PN, the plunger 14a is moved by the shift lever 5. Therefore, the durability of the solenoid 14 has a problem that, in addition to the case where the plunger 14a moves by the on / off control, the case where the plunger 14a is forcibly moved by the shift lever 5 must be considered.

Further, when the plunger 14a is moved by controlling the on / off of the solenoid 14, the lock pieces 11, 12 and the link 13 also move in conjunction therewith.
There is a problem that the sound when operating the solenoid 14 is loud and annoying.

The present invention has been made to solve the above-mentioned problems, and has been made to simplify the lock mechanism and reduce the driving means.
It is an object of the present invention to provide an inhibit device for a shift lever of an automatic transmission that can reduce a load and a driving frequency and reduce an operation sound.

This will be described with reference to FIG. In this embodiment, FIG.
The same components as those in 7 are denoted by the same reference numerals, and detailed description is omitted. Also, the operation of moving the shift lever 5 to each shift position is the same as in the related art, and a description thereof will be omitted.

As shown in FIG. 1, an inhibit lock mechanism 20 is provided near the shift pattern hole 4.
The inhibit lock mechanism 20 is provided with a lock piece 21 as locking means. The lock piece 21 includes a locking piece 22a formed in a U-shape and an arm piece 22b extending rearward from one side of the locking piece 22a. The lock piece 21 is supported by a guide (not shown) so as to be movable in the horizontal direction and immovable in the vertical direction.

A shaft hole 23 is formed at one end of the arm piece 22b. The shaft hole 23 is formed in a substantially triangular shape in the longitudinal direction (vertical direction in the figure) of the arm piece 22b, and one apex thereof is formed at an obtuse angle and is located at the center of the right side surface of the shaft hole 23. A fixed shaft 24 is inserted into the shaft hole 23. The lock piece 21 has a fixed shaft 24

One end of a first spring 25 is engaged with the arm piece 22b of the lock piece 21, and the other end of the first spring 25 is fixed to the shift lever housing 3. The first spring 25 is a tension spring, and holds the lock piece 21 so that the fixed shaft 24 is always located at the vertex on the right side.

One end of a second spring 26 is engaged with the right side of the locking piece 22 a of the lock piece 21, and the other end of the second spring 26 is fixed to the shift lever housing 3. The second spring 26 is a pressing spring, and always presses the lock piece 21 against a stopper 27 provided on the shift lever housing 3. Therefore, the lock piece 21 always has the first spring 25 and the second spring 26.
By the above, it is held by the fixed shaft 24 and the stopper 27.
The position of the lock piece 21 at this time is defined as an original position.

The locking piece 22a, which is formed in a substantially U-shape opened to the left, has a first locking portion 28 on the left front side.
The left rear portion is a second locking portion 29. Double locking part 2
Reference numerals 8 and 29 are arranged in the shift pattern holes 4 in a state where the lock piece 21 is pressed against the stopper 27 by the second spring 26 (original position). Therefore, the first locking portion 28 blocks the passage between the parking position PP and the reverse position PR of the shift lever 5, and the second locking portion 29 blocks the passage between the neutral position PN and the reverse position PR. ing.

When the first locking portion 28 closes the above-mentioned passage, the first locking portion 28 and the shift lever 5 at the parking position PP are engaged, and the shift lever 5 swings in the left-right direction. Is to be restricted. When the second locking portion 29 closes the above-described passage, the second locking portion 29 and the shift lever 5 at the neutral position PN engage,
The horizontal swing of the shift lever 5 is limited.

When the shift lever 5 at the parking position PP or the neutral position PN is swung in the left-right direction, the lock piece 21 is horizontally rotated about the fixed shaft 24 in the left-right direction based on the swing. It has become.

The inhibit lock mechanism 20 is provided with a solenoid 30 as moving means. A plunger 31 is provided on the solenoid 30. or,
The solenoid 30 is provided with a spring 32. Spring 3
Reference numeral 2 denotes a pressing spring, which causes the plunger 31 to protrude by the elastic force of the spring 32 when the solenoid 30 is in a non-excited state (OFF). On the other hand, when the solenoid 30 is in the excited state (ON), the plunger 31 is drawn inward against the elastic force of the spring 32. Plunger 31
A lock bar 33 as an operating body is fixed to the distal end of the lock bar 33.

The lock bar 33 is provided at a position where it comes into contact with the locking piece 22a of the lock piece 21 when the solenoid 30 is turned off, so as to limit the horizontal rotation of the lock piece 21 in the right direction. The position of the lock bar 33 at this time is defined as a lock position. When the lock bar 33 is at the lock position, the lock piece 21
3 and horizontal rotation in the right direction is restricted. At this time,
The lock piece 21 is movable in the front-rear direction, and moves by swinging the shift lever 5 in the front-rear direction.

On the other hand, when the solenoid 30 is excited (it is in the excited state and turned on), the lock bar 33 does not come into contact with the lock piece 21. The position of the lock bar 33 is referred to as a non-lock position. At this time, the lock piece 21 horizontally rotates rightward by swinging the shift lever 5 rightward.

In the vicinity of the shift pattern hole 4, a parking switch 34 and a neutral switch 35 are provided. The parking switch 34 is provided at a position where it is engaged with the shift lever 5 at the parking position PP, and is turned on (closed) in the engaged state. on the other hand,
The neutral switch 35 is provided at a position where it is engaged with the shift lever 5 at the neutral position PN, and is turned on (closed) in the engaged state.

Next, the electrical configuration of the above-described inhibit device for the shift lever of the automatic transmission will be described. FIG.
As shown in (1), an ignition switch 41 is connected to the control circuit 40. The ignition switch 41 is provided in a key cylinder (not shown) of the driver's seat 1.
A key lock solenoid 42 is provided in the key cylinder, and the key lock solenoid 42 is connected to the control circuit 40. When energized, the key lock solenoid 42 projects a plunger (not shown) to prevent the ignition key from rotating from a predetermined position, thereby preventing the ignition key from being pulled out.

A battery is mounted on the A / T vehicle, and a contact on one end of an ignition switch 41 is connected to the battery E. The ignition switch 41 is provided with an accessory contact ACC and an ignition contact IG, and is appropriately connected to the accessory contact ACC and the ignition contact IG based on a rotation operation amount of an ignition key (not shown). The two contacts ACC and IG are respectively connected to the control circuit 40, and the voltage of the battery E is used as an accessory power supply and an ignition power supply, respectively.
Supplied to The control circuit 40 is driven based on the supplied voltage of the battery E.

The control circuit 40 includes a parking switch 34
And the neutral switch 35 are connected. The control circuit 40 inputs the ON state of the parking switch 34 and detects that the shift lever 5 is at the parking position PP. Further, the control circuit 40 inputs the ON of the neutral switch 35, and the shift lever 5 is turned on to the neutral position PN.
Is detected. Then, the control circuit 40 turns on and off the solenoid 30 based on the detected position of the shift lever 5.

Further, a vehicle speed sensor 43 is connected to the control circuit 40, and detects the vehicle speed of the A / T vehicle when the A / T vehicle is traveling forward based on the state of the vehicle speed sensor 43. When the speed of the A / T vehicle is higher than a predetermined vehicle speed (10 km / h in this embodiment), the solenoid 30 is turned off and the shift lever 5 is turned off.
Is prevented from entering the reverse position PR.

Further, a brake switch 44 is connected to the control circuit 40, and the depression of the brake pedal 2 is detected by the brake switch 44. The control circuit 40 controls on / off of the solenoid 30 based on the detected depression of the brake pedal 2.

That is, the control circuit 40 comprises a parking switch 34, a neutral switch 35, a brake switch 4
The solenoid 30 is turned on (excited) and turned off (de-excited) according to conditions based on the state of the output terminal 4 and the output terminal of the vehicle speed sensor 43. And the solenoid 3
When the lock bar 33 is in the unlock position and the lock position, the horizontal rotation of the lock piece 21 in the right direction is restricted when the lock bar 33 is in the lock position. As a result, the movement of the shift lever 5 is restricted.

Next, the operation of the thus configured shift lever inhibit device of the automatic transmission according to the present embodiment will be described. When the driver rotates the ignition key to connect the ignition switch 41 to the accessory contact ACC, the voltage of the battery E is applied to the control circuit 40 via the accessory contact ACC. Then, the control circuit 40 sets the parking switch 34, the neutral switch 35,
The state of the vehicle speed sensor 43 and the state of the brake switch 44 are input, and the drive of the solenoid 30 is controlled according to conditions based on the states.

That is, the control circuit 40 controls the solenoid 30 to be off when the parking switch 34 is on and the shift lever 5 is at the parking position PP.
Then, the plunger 31 projects by the elastic force of the spring 32, and moves the lock bar 33 to the lock position. At this time, the lock piece 21 comes into contact with the lock bar 33, and the horizontal rotation of the lock piece 21 in the right direction is restricted. Therefore, the rightward swing of the shift lever 5 is restricted, and the parking position PP
Can not escape from

On the other hand, when the parking switch 34 is off and the shift lever 5 is not in the parking position PP, the control circuit 40 controls the solenoid 30 to be on. Then, the solenoid 30 pulls the plunger 31 inward against the elastic force of the spring 32, and moves the lock bar 33 to the unlocked position. Then, as shown in FIG.
The lock piece 21 does not contact the lock bar 33,
The horizontal rotation in the right direction becomes possible. As a result, the swing of the shift lever 5 is not restricted, and can be moved to an arbitrary shift position.

Next, the driver rotates the ignition key to turn the ignition switch 41 on the ignition contact I.
When connected to G, the voltage of the battery E is applied to the control circuit 40 via the ignition contact IG. Then, the control circuit 40 inputs the states of the parking switch 34, the neutral switch 35, the vehicle speed sensor 43, and the brake switch 44, and controls the drive of the solenoid 30 according to conditions based on the states.

A case where there is a vehicle speed, that is, a case where the A / T vehicle is traveling forward will be described. At this time, the shift lever 5 is located at any one of the fixed position P1 from the neutral position PN. The control circuit 40 detects the vehicle speed by the vehicle speed sensor 43 and controls the solenoid 30 to be turned off. Then, the plunger 31 projects by the elastic force of the spring 32 and moves the lock bar 33 to the lock position. At this time, as shown in FIG. 3, the lock piece 21 comes into contact with the lock bar 33, and the horizontal rotation of the lock piece 21 in the right direction is restricted. Therefore, when the shift lever 5 enters the neutral position PN while traveling, the rock piece 21 is restricted from swinging by the lock piece 21 and cannot be moved to the reverse position PR. As a result, it is possible to prevent the shift lever 5 from inadvertently moving to the reverse position PR during traveling.

Next, a case where there is no vehicle speed, that is, a case where the A / T vehicle is stopped and the brake switch 44 is turned on, that is, a case where the brake pedal 2 is depressed, will be described. At this time, the control circuit 40 controls the solenoid 30 to be ON regardless of the state of the parking switch 34 and the neutral switch 35. The solenoid 30 pulls the plunger 31 inward against the elastic force of the spring 32, and moves the lock bar 33 to the unlocked position. Then, as shown in FIG. 4, the lock piece 21 can be horizontally rotated rightward. Therefore, the shift lever 5 is in the parking position P
Since the swing in the left-right direction is not restricted at the time of P or the neutral position PN, it is possible to move to an arbitrary shift position between the parking position PP and the fixed position P1.

On the other hand, the case where the A / T vehicle is stopped and the brake switch 44 is off, that is, the case where the brake pedal 2 is not depressed, will be described. At this time, when the shift lever 5 is at the parking position PP, the parking switch 34 is turned on by the shift lever 5. The control circuit 40 inputs the ON of the parking switch 34,
The solenoid 30 is turned off, and the lock bar 33 is moved to the lock position. Therefore, the lock piece 21 abuts on the lock bar 33, and the horizontal rotation of the lock piece 21 in the right direction is restricted. As a result, the rightward swing of the shift lever 5 is limited, and the shift lever 5 cannot escape from the parking position PP.

When the shift lever 5 is in the neutral position PN, the neutral switch 35 is turned on by the shift lever 5. The control circuit 40 inputs the ON of the neutral switch 35, controls the solenoid 30 to be OFF, and moves the lock bar 33 to the lock position. Therefore, the lock piece 21 abuts on the lock bar 33, and the horizontal rotation of the lock piece 21 in the right direction is restricted. As a result, the swing of the shift lever 5 is restricted, and the shift lever 5 cannot move from the neutral position PN to the reverse position PR.

When the shift lever 5 is in the reverse position PR
In some cases, the lock bar 33 may be in the locked position. At this time, the shift lever 5 is moved to the parking position PP.
, The shift lever 5 is first moved forward to engage the first locking portion 28. Then, after the shift lever 5 is moved in the forward direction against the elastic force of the first spring 25, and then moved to the left, the shift lever 5 can be moved to the parking position PP. After the shift lever 5 moves to the parking position PP, the lock piece 21 is pulled backward by the first spring 25 and moves to the original position.

On the other hand, the shift lever 5 is moved to the reverse position PR.
In order to move the shift lever 5 from the neutral position PN to the parking position PP, the shift lever 5 is first moved backward so as to engage the second locking portion 29. Then, the shift lever 5 can be moved to the neutral position PN by moving the shift lever 5 in the backward direction against the elastic force of the first spring 25 and then moving it to the left. After the shift lever 5 moves to the neutral position PN, the lock piece 21 is pulled forward by the first spring 25 and moves to the original position.

As described in detail above, in this embodiment,
The inhibit lock mechanism 20 for restricting the movement of the shift lever 5 is separated into a lock piece 21 and a lock bar 33, and the lock bar 33 is disengaged from the plunger 31 of the solenoid 30.
It was fixed and moved. As a result, since the solenoid 30 only moves the lock bar 33, the load on the solenoid 30 is reduced, and the solenoid 30 can be operated stably.

When the shift lever 5 is moved to the reverse position PR.
When the lock piece 21 is moved from the first position to the parking position PP or the neutral position PN, only the lock piece 21 rotates back and forth, so that the plunger 31 of the solenoid 30 is not forcibly moved. As a result, the operation frequency of the solenoid 30 is reduced, and the durability is improved accordingly.

Further, when the solenoid 30 is driven, only the lock bar 33 is moved by the movement of the plunger 31, so that the noise generated when the solenoid 30 is operated can be reduced.

The present invention is not limited to the above embodiment, but may be implemented as follows. (1) In the above embodiment, a tension spring is used as the first spring 25 for holding the lock piece 21. However, the lock piece 21 may be held at the original position using a pressing spring or the like. Further, the lock piece 21 is brought into contact with the stopper 27 by using the second spring 26 which is a pressing spring. You may.

(2) In the above embodiment, the arm piece 22b of the lock piece 21 is formed so as to extend forward from one side of the locking piece 22a, and the fixed shaft 24 is inserted into the shaft hole 23 formed in the arm piece 22b. You may make it insert and implement.

(3) In this embodiment, a three-speed automatic transmission is used, and a drive position PD for performing automatic forward shift of all transmissions, and fixed positions P1 and P fixed to each of three forward speeds.
Although P2 and P3 are set, they may be set arbitrarily, such as being set at the drive position PD and the fixed positions P1 and P2. Further, the present invention may be implemented using an automatic transmission capable of performing two-speed shifting or four or more-speed shifting.

Further, the present invention is not limited to the shape of the shift pattern hole 4 of the present embodiment, and the shape may be appropriately changed. (4) In the present embodiment, the neutral switch 35 engaged when the shift lever 5 is at the neutral position PN.
Is provided to detect that the shift lever 5 is at the neutral position PN. However, a neutral detection switch for detecting that the shift element of the automatic transmission does not operate is provided, and the detection result of the neutral detection switch is provided. It may be configured to detect that the shift lever 5 is in the neutral position PN based on this.

(5) Shift pattern hole 4 of the above embodiment
May be implemented by appropriately changing the above-described embodiment to a shape obtained by mirror inversion in the left-right direction or the like. that time,
It goes without saying that the arrangement / shape of the inhibit lock mechanism 20 is changed corresponding to the shift pattern hole 4.

(6) In the above embodiment, the control circuit 40 is provided with the solenoid 30 and the key lock solenoid 42, but the control circuit 40 may be provided with only the solenoid 30. (7) In this embodiment, the control circuit 40 controls the solenoid 3 based on the states of the parking switch 34, the neutral switch 35, the vehicle speed sensor 43, and the brake switch 44.
Although the on / off control of 0 is performed, the combination may be appropriately changed and executed.

In the above embodiment, when the vehicle speed is 10 km / h or more, the solenoid 30 is turned off and the movement of the shift lever 5 is limited by controlling the solenoid 30 to be off, but the vehicle speed is changed to an appropriate value. When the value is equal to or greater than the value, the solenoid 30 may be turned off to restrict the movement of the shift lever 5.
