Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for handling a transmission shift wire in a one-box car, for example.

[0002]

[Prior Art]

 In the current transmission 1 in a one-box car shown in FIG. 3, for example, the take-out direction of the shift rod 2 is determined based on the gear arrangement, the configuration of shaft parts, the space in the engine room, etc. In the transmission 1 which has a continuously variable transmission, the shift rod 2 is currently taken out to the front F side. A lever 3 having a predetermined length is attached to the tip of the shift rod 2, and the end of the lever 3 is attached. The end of the shift wire 4 was pivotally attached to the section, and the shift wire 4 was routed above the transmission 1.

[0003]

[Problems to be solved by the device]

 However, when the shift rod 2 is taken out, the taken-out length is also limited, and therefore the radius of curvature R for bending the shift wire 4 cannot be set large, so that the shift rod 2 that connects the shift wire 4 is connected. The shift wire 4 is connected by extending it as much as possible. However, since the shift wire 4 is routed from the position shown in the front of the transmission 1, the curvature R of the shift wire 4 can still be largely controlled. Therefore, there was a problem that the operating force of the shift lever became heavy.

The present invention has been made to solve the above-mentioned conventional problems. Even if the shift rod 2 is taken out on the front side, the shift wire can be provided with a large curvature and the shift wire can be shifted. It is an object of the present invention to provide a structure for handling a shift wire of a transmission, which can reduce the operating force of a lever.

[0005]

[Means for Solving the Problems]

 In order to solve the above technical problem, in a shift rod taken out to the front side of a vehicle of a transmission, the upper end of the linkage rod is projected from the upper end of the transmission through a top of a shiftable shaft from a take-out end of the shift rod. This is because the shift wire routing structure of the transmission is configured to hold the shift wire vertically.

[0006]

[Action]

 With the above configuration, the radius of curvature of the bend for handling the shift wire can be increased and the shift wire can be handled, and the shift operation force can be reduced.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIG. 1. Reference numeral 10 denotes an outer shell of a transmission case, and a take-out portion 11 of a shift rod 12 is formed at a predetermined position on the front side of the transmission case 10. An end portion of the shift rod 12 is projectingly provided on the extraction portion 11 in a short length of a predetermined length. In this way, the linkage bracket 13 is formed on the upper portion of the take-out portion 11 on which the shift rod 12 is projectingly provided.

The linkage bracket 13 holds the linkage rod 14 vertically and rotatably supports the linkage rod 14. The linkage rod 14 supported by the linkage bracket 13 has a predetermined length, and has an upper end. A lever 15 having a predetermined length is attached in a rectangular shape, and the lower end portion of the linkage rod 14 and the protruding end portion of the shift rod 12 are connected to each other via a top type universal shaft coupling 16.

As shown in FIG. 2, the top-type universal shaft coupling 16 is composed of left and right joint members 17 and 18 and a top member 27. The joint members 17 and 18 are formed in the same configuration. The main body 19 is formed in a substantially cylindrical shape having an inner diameter 20 into which the shift rod 12 or the linkage rod 14 can be fitted. A concave groove 21 into which a claw 22 is fitted and fixed is provided at a corresponding position in the diametrical direction of the main body 19. The pair of claws 22 is provided with a mounting piece 23 that can be fitted into the concave groove 21 and a circularly projecting claw 24 on the inner surface of the tip of the mounting piece 23. As shown in the drawing, an oil hole 25 that penetrates the center of the claw 24 is provided through. The sheath 26 is formed into a cylindrical shape that is fitted onto the main body 19. The claw body 22 is fixed in such a manner that the claw body 22 is fitted into the concave groove 21 of the main body 19 with the claws 24 facing each other, and the sheath body 26 is externally fitted to the outer periphery of the claw body 22. Is fixed in a bifurcated manner.

Further, the top member 27 is formed into a spherical body having a predetermined diameter, and a fitting hole 28 into which the claw 24 of the claw body 22 is rotatably fitted is formed so as to penetrate in a direction orthogonal to the spherical body. The opening end of the fitting hole 28 is chamfered. In the fitting hole 28 of the top member 27 thus formed, the claws 24 of the pair of joint members 17 and 18 are fitted to form the shaft joint 16.

When one joint member 17 of the thus formed shaft coupling 16 is fitted to the projecting end portion of the shift rod 12 and the other joint member 18 is fitted to the lower end portion of the linkage rod 14 for connection. The lever 15 attached to the tip of the linkage rod 14 is located slightly above the outer upper portion of the transmission case 10.

As described above, the shift wire 30 is connected to the lever 15 at the upper end of the linkage rod 14 vertically held via the shaft coupling 16 at the end of the shift rod 12 while the connector 31 is held horizontally. Are being circulated.

Therefore, according to the present embodiment, the shift wire 30 horizontally connects the connector 31 to the lever 15 at the upper end of the linkage rod 14 which is vertically held at the extraction end of the shift rod 12 via the shaft coupling 16. Since the shift wire 30 is connected and routed in a held state, the shift wire 30 can be routed while holding the connector 31 at the base of the attachment horizontally. The radius of curvature can be increased, the shift operation force can be reduced, the shift feeling can be improved, and the durability of the shift wire 30 can be improved.

[0014]

[Effect of the device]

 As described above, the shift wire is connected to the lever at the upper end of the linkage rod held vertically by the take-out end of the shift rod via the top type universal shaft coupling while the connector is held horizontally. Since the shift wire can be routed while holding the connector at the base of its attachment horizontally, the shift wire can have a large radius of curvature. The shift operating force can be reduced, the shift feeling can be improved, and the durability of the shift wire can be improved.
