Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a first clutch and a second clutch, and torque transmission from the first clutch (2) and torque transmission from the second clutch 4 are properly controlled. This relates to a twin-clutch type **transmission that can be obtained in translation.

For rounding to obtain a predetermined number of variable stages, for example, four-pronged variable a stages,
A transmission gear from 1st speed to 4th gear is installed on one shaft that is installed inside the Transmif S/17 case.
If the driven gears that mesh with the transmission gears for 1st to 4th gears are placed on the other shaft, the axial lengths of these shafts will become longer, and this will tend to make the machine larger in the axial direction. . Furthermore, since the gear ratio is set by the gear ratio of each gear and the driven gear that meshes with it, the width of the variable +II ratio tends to be narrow, and it is difficult to obtain a predetermined gear ratio. It may happen.

An object of the present invention is to shorten the axial length of the V shaft on which the transmission gear is disposed, and to shorten the axial length of the entire variable filter loss by this amount. It is an object of the present invention to provide a gear transmission which can be easily set in a wide range of gear ratios and can easily set a desired gear ratio.
