Problems solved by technology

However, since the length of each inclined surface of the cam surface 3b is relatively small relative to the diameter of the ball 8, it is difficult to bend each inclined surface to adjust the shift feeling.
Also, since it is not possible to have different load characteristics when entering and exiting a shift, it is difficult to properly adjust the shift feel

Embodiment Construction

[0026] The present invention is suitable for Figure 8 or Figure 10 An embodiment of the operation shaft of the shift mechanism that moves in the axial direction, such as the fork shaft in the shift and select mechanism shown, will be described below.

[0027] exist figure 1 with figure 2 Among them, the operating shaft 25 is a member provided in the shift mechanism freely movable in the axial direction, and a radially protruding portion 26 having a spherical surface is formed on a part thereof. The cylindrical holding member 21 is fixed inside the transmission case of the transmission, and is fixed concentrically with the operation shaft 25 . The four leaf springs 30 are symmetrically arranged, surround the radially protruding portion 26 of the operation shaft 25 , and are coupled to the spherical surface of the radially protruding portion 26 . Each plate spring 30 is made of metal, and has a V-shaped concave portion 31a in its central portion coupled with the radially ...

Abstract

An operation device of a shift mechanism in a manual transmission includes a cylindrical support member fixedly mounted within the transmission housing in such a manner that a radial projection on an operation shaft of the shift mechanism is concentrically placed in the cylindrical support member and a leaf spring having a central portion formed with a V-shaped concave to be engaged with the radial projection of the operation shaft and a pair of side portions fixed to opposite ends of the cylindrical support member such that the V-shaped concave is maintained in engagement with the radial projection to retain the operation shaft in a neutral position, whereby load of the leaf spring acting on the operation shaft respectively when shifted in one direction and in the other direction can be adjusted in different characteristics.

Description

technical field [0001] The present invention relates to an operating device for a shift mechanism in a manual transmission, and more particularly, to an operating device for a shift mechanism capable of properly adjusting the load characteristics of a shift stroke during shift and select operations. Background technique [0002] In Japanese Patent Laid-Open No. 2004-100741, a manual transmission is proposed, which has a plurality of transmission gear pairs arranged between an output shaft and a countershaft installed in parallel with each other inside the transmission case, and A shift / selection mechanism is provided to select and operate a plurality of switching mechanisms between these pairs of transmission gears. The output shafts are selectively engaged to complete the power train. [0003] Such as Figure 8 As shown, the gearshift and gear selection mechanism in the above-mentioned manual transmission has three fork shafts 4 (one fork shaft is shown in the figure) that...
