Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a control lever device for a transmission.

[Prior Art] For example, as disclosed in Japanese Utility Model Application Publication No. 58-15535, when a gear shift lever is operated to a required select operation position and a required shift operation position, a predetermined switch is closed at this position. 2. Description of the Related Art A gear shift lever device has been proposed in which the select operation and shift operation of a gear transmission can be performed remotely by an actuator. In this prior art, the switch is closed by performing the same operation as the shift lever of a manual gear transmission.

By the way, a clutch actuator, a select actuator, and a shift actuator are connected to the clutch mechanism and gear transmission in a vehicle, respectively, and the fluid pressure circuit of these actuators is controlled by the engine speed, engine load, and accelerator pedal pressure. Automatic gear transmissions have already been put into practical use, which are controlled by the output of a microcomputer that receives an electrical signal corresponding to the amount of pedal stroke, automatically disconnects and connects the clutch mechanism, and sets the gear transmission to the optimum gear position. ing.

In this automatic gear transmission, the control lever that replaces the gear shift lever is simply electrically connected to the electronic control device of the gear transmission, and the control lever can be moved to the parking position P and reverse gear R in the same way as in conventional automatic vehicles. , range D, 2nd gear and 1st gear.

That is, as shown in FIGS. 2 and 3, the conventional transmission control lever device
Preferably, arcuate elongated holes 8 are provided in both side walls 4 of the bracket 2, which is bent into a letter shape, and a corrugated moderation plate 6 having a recess 6a is fixed to the bottom wall 5 by welding or pins.

On the other hand, a block 7 connected to the control lever 1 is housed inside the bracket 2, and a roller 3 supported on both side walls 4 is rotatably engaged with the elongated hole 8 described above. An engaging member 10 with a hemispherical tip is supported by the block 7 and is projected downward from the bottom wall by a spring. When the engaging member 10 engages with the recess 6a, the control lever 1 is operated. held in position. The moderation plate 6 and the engagement member 10 constitute a detent mechanism.

Block 7 is urged upward by the spring force of the detent mechanism. A gap a is provided between the side wall of the block 7 and the side wall 4 of the bracket 2, and a gap b is provided between the roller 3 and the elongated hole 8 so that it can slide smoothly between the both side walls 4. Each is provided.

In this conventional control lever device for a transmission, when the control lever 1 is moved in the longitudinal direction (arrow As a result, the block 7 is pushed up, and the block 7 is guided along the elongated hole 8 by the four rollers 3.

However, since a gap is provided between the elongated hole 8 and the roller 3, when the control lever 1 is tilted to the side as shown in FIG. ) makes a strong point contact, making the sliding movement in the front and rear (arrow

[Problems to be solved by the invention] The purpose of the invention is to solve the above-mentioned problems.
To provide a control lever device for a transmission that has a simple configuration and allows smooth operation even when the control lever is tilted to the side.

[Means for Solving the Problem] In order to achieve the above object, the present invention has a structure in which a shift block is slidably disposed inside a bracket having a U-shaped cross section, and rollers supported on both side walls of the shift block are provided. is rotatably supported in elongated holes provided in both side walls of the bracket, and the roller is shaped like a drum.

[Function] By making the roller 3 that engages with the elongated hole 8 of the bracket 2 drum-shaped, even if the block 7 is tilted to the side together with the control lever 1, the roller 3 contacts the center surface of the elongated hole 8. However, since the rollers 3 roll smoothly, even when the control lever 1 is tilted to the side, the selection operation can be performed smoothly in the front-rear direction.

[Example of the invention] The invention will be explained based on an example. As shown in FIG. 1, the roller 3 that engages with the elongated hole 8 of the bracket 2 is shaped like a drum. The other configurations are similar to the conventional example shown in FIGS. 2 and 3.

By configuring the present invention as described above, even if the block 7 is tilted to the side together with the control lever 1, and the shaft 13 of the roller 3 is also tilted, the roller 3 will not touch the center surface of the elongated hole 8 (the side wall 4). Since the rollers 3 contact each other at the center of the thick plates, smooth rolling of the rollers 3 can be achieved. Therefore, even when the control lever 1 is tilted to the side, the control lever 1 can be smoothly moved in the front-back direction.

[Effects of the invention] As mentioned above, the present invention allows the bracket and its elongated hole to be easily manufactured from a thick plate by press molding, etc., so it is easy to reduce costs through mass production, and the block can be shaped like a drum. Since the rollers are supported, even when the control lever is tilted to the side and moved back and forth, the rollers are guided by rolling on the central surface of the elongated hole, preventing them from getting caught. The problem is resolved,
Provides smooth control lever operation.
