Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shift lever device, which is an operation part of a transmission, for switching a driving force of an engine according to a vehicle speed and a traveling direction in a large vehicle.

[0002]

[Prior art]

 In automobiles and other vehicles, a shift lever is arranged between a driver's seat and a passenger's seat as an operation unit of a transmission that switches an engine driving force (gear ratio) and a traveling direction according to a driver's instruction. Such a shift lever is particularly useful in a cab of a truck or other large vehicle, when the occupant stands up and moves inside the cab when the vehicle is stopped. In order to make it easier for passengers to get on and off the vehicle, it has been proposed to have a mechanism for tilting it from the state of being erected in the cab to the passenger seat side (Jpn. Pat. Appln. KOKAI No. 3-2047).

[0003]

[Problems to be solved by the device]

 By the way, in such a conventional shift lever device, when the gear ratio or the like is changed during traveling, the shift lever is shifted in the traveling direction of the vehicle (hereinafter, referred to as "shift stroke direction") according to the operation of the driver. When the vehicle is stopped, the shift lever is tilted in a direction substantially perpendicular to the above-mentioned shift stroke direction (hereinafter referred to as “the retractable stroke direction”). Was attached via two joint portions individually corresponding to.

Therefore, in the conventional shift lever device, the structure of the joint portion described above is complicated, the number of constituent parts is large, and the mechanical size is large. It is an object of the present invention to reduce the number of parts by unifying a joint portion, thereby achieving size reduction and weight reduction.

[0005]

Means for Solving the Problems The present invention is characterized in that a support metal fitting is fixed to a vehicle floor side bracket, and a shift lever is provided on the support metal fitting via a ball joint.

[0006]

[Action]

 In the shift lever device for a vehicle transmission according to the present invention, since the shift lever is provided on the floor side of the vehicle through the ball joint, the operability in the shift stroke direction and the tiltable stroke direction is maintained. The parts are unified.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention.

In the drawing, a plate-shaped vehicle-side floor-side bracket (hereinafter simply referred to as “bracket”) 10 is fixed in parallel to the floor surface of the cab via an angle 11, and is attached to the upper surface of the bracket 10. A support metal fitting 12 is fixed, and a shift lever 14 is erected on the support metal fitting 12 via a ball joint 13 so as to be rotatable in a shift stroke direction and a tilting stroke direction. A bracket 15 is fixed to the base of the shift lever 14, and its tip is connected to a shift control input of the transmission via a cable. The shift lever 14 is formed of a pipe material whose main part of the outer casing has a rectangular cross section, and a knob 16 is joined to the other end of the shift lever 14. A push button 17 is attached to the knob 16 from the inside to the side surface on the driver's seat side, and the push button 17 is connected to one end of a predetermined mechanism portion provided in the cavity in the knob 16 and the shift lever 14. . Of the four side surfaces of the shift lever 14, a single hole is formed in the vicinity of the joint with the ball joint 13 on the side facing the driver's seat, and the hole has the above-mentioned mechanism as shown in FIG. A protrusion 21 is loosely fitted and protruded from the other end of the portion. Furthermore, an L-shaped check plate 22 is erected on the bracket 10 along the tiltable stroke direction. On the side surface of the check plate 22, a comb-shaped notch that is joined to the protrusion 21 by the rotation of the shift lever 14 in the tiltable stroke direction, and the protrusion 21 is formed when the shift lever 14 rotates in the tiltable stroke direction. A cam groove 23 consisting of a notch along the drawn trajectory is formed. As shown in FIG. 1, a bracket 15 is formed by forming a single hole at the other end of the support fitting 12 and bending the hole portion toward the passenger seat substantially at a right angle. Such a hole of the bracket 15 is connected to the transmission through a predetermined cable. As shown in FIG. 1, a shift lever cover 20 having an L-shaped guide hole 19 is formed on the upper surface of the bracket 10 along the shift stroke direction and the tiltable stroke direction. It is installed parallel to the height where collision with can be avoided. Further, on the side surface of the shift lever cover 20, as shown in FIG. 2, a hole that engages with the side surface and a groove that extends the above-described L-shaped guide hole 19 to the vicinity of the upper surface of the bracket 10 are formed. A console cover 24 is formed so as to cover the lower end of the angle 11.

In the shift lever device having such a configuration, the shift lever 14 is used in a state of standing up against the floor of the cab when there is no particular obstruction during traveling or when the vehicle is stopped. . In such a state, the shift lever 14 is set to a position that can be shifted in the shift stroke direction along the guide hole 19, and that position is located in the protrusion 21 among the plurality of depressions carved in the cam groove 23. It is fixed in the engaged recess.

The protrusion 21 loosely fits in the cam groove 23 via the above-mentioned mechanism portion when the driver pushes the push button 17, and enables the shift lever 14 to rotate in the shift stroke direction. The lever 14 is rotated in the shift stroke direction to set the position corresponding to the desired gear ratio, and then the push button 17 is released to engage with the groove of the cam groove 23 corresponding to that position. Therefore, the shift lever 14 is fixed at a position corresponding to the updated gear ratio along the shift stroke direction.

Since the bracket 15 moves in the shift stroke direction in conjunction with the position of the shift lever 14 set in this way, the transmission connected via the cable is controlled and the gear ratio and other settings are variably set. It

Further, the shift lever 14 is set to a position corresponding to the bent portion of the guide hole 19 by a driver's operation when the vehicle is stopped. Further, for example, when the driver changes or gets on and off through the door on the side opposite to the seat where the occupant is seated, the occupant pushes down the shift lever 14 in the direction of the inclinable stroke, and The shift lever 14 that interferes with the movement of the person standing up in the cab is stored in a low position.

As described above, according to this embodiment, by using a single ball joint as a joint for rotating the shift lever 14 in the shift stroke direction and the tiltable stroke direction, the function of the shift lever is improved. The number of components can be reduced while maintaining the cost, and the cost and size can be reduced.

[0014]

[Effect of device]

 As described above, the present invention employs a single ball joint to rotate the shift lever in the shift stroke direction and the tilt stroke direction, thereby reducing the number of components.

Therefore, the shift lever device can be made inexpensive and downsized, and in the vehicle to which the present invention is applied, the reliability can be improved while maintaining the operation environment.
