IPC: F16D25/0638
Filed: 1986-04-11
Abstract: PURPOSE:To relieve the shock at the time of the start, by providing a portion of plural clutch units, which are given a fitting or detaching motion by an oil pressure working part, with another oil pressure working part, which starts its motion with the pressure lower than that for the other clutch units. CONSTITUTION:A cylinder 19 is formed at a part of an advancing force input gear of an advancing force supporting shaft 12a, while an operating oil pressure chamber 24 is formed between the cylinder 19 and a piston body 20 that is pushed by a return spring 22. In addition, a wall surface of the piston body 20 is indented in order to form an initial, pressure receiving chamber 25a. Thus, the greater the pressure receiving area is, the lower the oil pressure, at which the piston starts its motion, becomes, and the piston pushes a multiple disc clutch part 34, thereby realizing a clutch-fit-in state. In this connection, another advancing force supporting shaft is formed in the same way as the said shaft 12 except that the pressure receiving area of the initial, pressure receiving chamber is made smaller than the above case. Accordingly, both advancing force supporting chambers cooperate with each other in putting on or off the power between the input shaft and the output shaft, thereby shortening the clutch-fit-in time and also relieving the shock.

When the second-hand pinion 22 is rotated in the clockwise direction, an inner interlinking pinion 27 and an inner interlinking gear 26 are turned in the counterclockwise direction. An outer interlinking gear 28 and an outer interlinking gear 29 are turned in the clockwise direction. Furthermore, an inner gear 30 and the minute-hand pinion 23 are turned in the clockwise direction. Since this train wheel is the speed reducing train wheel, the minute-hand pinion 23 is rotated by one turn when the second-hand pinion 22 is turned by 60. times. The minute-hand pinion 23 is rotatably coupled with an hour wheel 31, and the speed reduction ratio is set at 1/12. Therefore, when the minute-hand pinion 23 is turned by 12 times, the hour wheel 31 is turned by one turn. Thus, a plurality of the gears are consolidated and the number of the gears is reduced in this composite gear 20. Therefore, the plane space can be widely opened.
