Abstract

PURPOSE: To aim at providing a speed change clutch which can be easily manufactured and which has a shortened synchronizing time, by loosely fitting a clutch casing having a hydraulic piston and friction plates, for transmitting the rotating power of an output shaft, onto an input shaft which is also fitted thereon with a holder for supporting friction plates, and by forming oil passages for feeding lubricating oil between the friction plates.
CONSTITUTION: A clutch casing 23A having a hydraulic piston 23 and friction plates 27a is rotatably journalled to an input shaft 22 by means of a needle bearing 26, and a holder 28 supporting friction plates 27b disposed between the friction plates 27a is fitted on the input shaft 22 by means of a spline structure. Lubricating oil which is fed into a pipe line 33 through a grooved oil passage 35 formed outside of the needle bearing 26 and an oil passage 35 formed between the input shaft 22 and the clutch casing 23A, is fed between the input shaft 22 and a clutch casing 23. Accordingly, it is possible to make the rotation smooth with a simple machined structure, and to prevent the friction plates from rotating in association with each other, thereby the synchronizing time is shortened.
