Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shift lever device for operating a vehicle transmission.

[0002]

[Prior art]

 For example, in a shift lever device that operates an automatic transmission that is a vehicle transmission, a desired shift position of the automatic transmission is selected by a shift lever inside the vehicle. This shift lever has a structure in which the detent pin provided on the shift lever moves in the axial direction of the shift lever, so that the detent pin and the detent plate are disengaged from each other and the shift position can be selected. .

Here, as such a shift lever device, one shown in FIG. 2 is known as an example. The shift lever device shown in FIG. 2 has a groove 52A for restricting a shift position formed at the lower edge of the detent plate 52 fixed to the base plate 54, and any one of the grooves 52A is formed. The detent pin 58 protruding from the shift lever 50, which is rotatably supported by the rotary shaft 56 of the base plate 54, is fitted into the crab and the shift position is regulated.

The automatic transmission is connected to the shift lever 50 by a link or the like (not shown) extending from the rotary shaft 56, and the rotational operation of the shift lever 50 is transmitted to the automatic transmission. .

When the vehicle starts or shifts, the occupant pushes the button 62 of the shift knob 60 attached to the shift lever 50 to push down the detent pin 58 and push the detent pin 58 to the detent plate 52. After releasing the engagement, the shift position was changed.

[0006]

[Problems to be solved by the device]

 By the way, in such a shift lever device, since a link or the like is interposed between the detent plate 52 and the automatic transmission, there is rattling present at the joint of the link or the like when the vehicle suddenly starts or stops. The shift position of the automatic transmission and the shift position of the shift lever 50 may be deviated from each other, which causes a shift omission.

Further, in order to solve the above-mentioned drawbacks, in order to improve the shape accuracy of the link, it is necessary to improve the dimensional accuracy of the parts, which results in an excessive manufacturing cost.

In view of the above facts, the present invention has an object to obtain a shift lever device capable of preventing shift omission while reducing cost.

[0009]

[Means for Solving the Problems]

 The shift lever device according to the present invention is rotatably attached to a transmission side for changing the traveling speed of a vehicle, and a detent plate for operating the transmission to change the speed by rotating the detent plate, and is connected to the detent plate. Moreover, a shift lever for operating the transmission through the detent plate, a pin that engages with the detent plate to limit the rotation of the detent plate, and the pin based on signal information from the inside of the vehicle. The position of the pin between a detent plate stop position that is connected to the pin for movement and that limits the rotation of the detent plate and a detent plate stop release position that allows the detent plate to rotate. And a pin moving means for changing.

[0010]

[Action]

 The pin moving means moves the pin based on the signal information from the inside of the vehicle, and when the pin is in the detent plate stop release position, the detent plate can be rotated.By operating the shift lever, the detent plate can be rotated. Transmission is operated.

The pin moving means moves the pin based on the signal information from the inside of the vehicle, and when the pin engages the detent plate and is in the detent plate stop position, the detent plate cannot be rotated and the shift is performed. Even if the lever is operated, the detent plate does not rotate, and as a result, the transmission is not operated.

Therefore, it is not necessary to improve the dimensional accuracy of each component such as the link in order to prevent the shift omission, and the shift lever device can be manufactured at an extremely low cost.

[0013]

【Example】

 An embodiment of the shift lever device according to the present invention is shown in FIG. 1, and the present embodiment will be described based on this drawing.

As shown in FIG. 1, the middle portion of the shift lever 10 is rotatably supported by a base plate 14 of the operation panel 12 via a rotation shaft 16, and is attached to the upper end portion of the shift lever 10. A shift knob 11 for gripping and operating the shift lever 10 by an occupant is attached, and a shift lock button 18 which is a switch for enabling the rotation of the shift lever 10 is installed on the shift knob 11. A link 20 is rotatably connected to the lower end of the shift lever 10.

A neutral start switch 22 attached to an automatic transmission (not shown), which is a transmission, is located near the other end of the link 20, and the main body of the neutral start switch 22 has a transmission shift function. A detent plate 24 is rotatably supported via a rotary shaft 25 for changing the position. The link 20 is rotatably connected to the connecting portion 24A extending to the lower end side of the detent plate 24, and the detent portion 26 formed in a fan shape on the upper end side of the detent plate 24 has a plurality of connecting portions. A groove 27 is formed.

A solenoid 28 is attached to a vehicle body (not shown) so as to face the concave groove 27 of the detent portion 26, and the plunger 28 A extending from the solenoid 28 is extendable and retractable. A pin 30 that extends in a direction orthogonal to 28A and that fits into the groove 27 of the detent portion 26 while the plunger 28A is extended is fixedly connected. Further, the pin 30 is also fitted in the elongated hole 32 formed in the transmission, and the pin 30 serves as a guide when the plunger 28A expands and contracts, and also fits in the concave groove 27 of the detent portion 26. In the open state, it serves to prevent rotation of the detent plate 24.

That is, when the solenoid 28 is energized or deenergized, the solenoid 28 is actuated to extend the plunger 28 A, and the pin 30 is engaged with the groove 27, so that the detent plate 24 is rotated. Movement is limited. Therefore, the position of the pin 30 in this state is called the detent plate stop position. Further, when the solenoid 28 is actuated and the plunger 28A is contracted and the pin 30 is disengaged from the groove 27, the content plate 24 can be rotated. Therefore, the position of the pin 30 in this state is called the detent plate stop release position.

On the other hand, the solenoid 28 is connected to a power source 34 via a controller 35 that controls the operation of the solenoid 28, and the solenoid 28 is activated by the current sent from the power source 34. In addition to the brake pedal (not shown), the controller 35 is also connected to a key interlock 38 attached to a steering column 37 that supports the steering 36, and a signal generated by the brake pedal based on depression of the brake pedal and a key pedal. A signal generated by the key interlock 38 based on the rotation is sent to the controller 35.

On the other hand, the controller 35 is also connected to the shift lock button 18 located at the upper end portion of the shift lever 10, and when the shift lock button 18 is pushed, an operation signal of the button is sent from the shift lock button 18 side to the controller 35. It is supposed to be sent.

Further, a sensor such as a rotary encoder (not shown) that detects a rotation angle of the detent plate 24 around the rotation shaft 25 is attached to the neutral start switch 22, and the controller 35 is also connected to this sensor. Has been done. Therefore, the rotation angle signal indicating the shift position of the detent plate 24 is sent from the sensor to the controller 32.

That is, the solenoid 28 operates while being controlled by the controller 35 based on the signal information from the vehicle which is a shift lock related signal from the brake pedal, the key interlock 38, the shift lock button 18, and the sensor. The rotation of the detent plate 24 is restricted or enabled based on the respective signals. Therefore, the solenoid 28 and the controller 35 serve as pin moving means.

Next, the operation of the shift lever device according to this embodiment will be described. For example, while the vehicle is traveling, a signal based on the operation of the shift lock button 18 is sent to the controller 35, and the solenoid 28 is operated under the control of the controller 35 to change the shift position only when necessary. Also, when the signal is stopped once, the shift lever 10 is operated to rotate to the N range which is the neutral range. After this rotation, the solenoid 28 operates and the pin 30 corresponds to the N range. The detent plate 24 will enter the concave groove 27.

When starting, the shift position is changed to a travel range such as the D range by operating the shift lever 10 while depressing the brake pedal. In other words, as a result of the signal indicating that the brake pedal is depressed being sent to the controller 35 connected to the brake pedal, the solenoid 28 is activated and the pin 30 is disengaged from the groove 27, so that the shift position is changed. Is possible.

Further, after the shift position is changed and the depression of the brake pedal is stopped, the solenoid 28 operates again, and the pin 30 is engaged with the groove 27 of the detent plate 24 corresponding to the D range. Becomes

Further, when the vehicle is stopped and the key is removed from the steering column 37, the key interlock 38 is actuated and the key can be removed only in the P range which is the parking range. Also in this case, the solenoid 28 operates so as to be fixed at the shift position of the P range, and the pin 30 engages with the groove 27.

On the other hand, even when the vehicle is suddenly started or suddenly accelerated, the pin 30 engages with the concave groove 27 of the detent plate 24 corresponding to a required range, but the detent plate 24 and the automatic Since the neutral start switch 22 attached to the transmission is connected without a link, the detent plate 24 does not rotate even if a shock occurs due to sudden start or sudden acceleration. Compared with, it is possible to prevent shift omission without increasing the shape accuracy of the link.
