摘要： PURPOSE:To enable a transmission to suddenly switch to a reverse speed change shift, when an electric vehicle is desired to switch to reverse running, based on preventing a reverse drive by a one-way clutch. CONSTITUTION:When a motor 1 is driven, forward rotation of a shaft 3 is transmitted to a wheel through a clutch 5 and a transaxle 2, to an electric vehicle. Stopping is attained by only deenergizing the motor 1. When this stopping the vehicle is performed on an ascending road, reversing the vehicle can be prevented by a one-way clutch 6. Here with reversing desired, in order to place the transaxle 2 in a reverse speed change shift, when a manual clutch 5 is released, a transaxle input shaft 4 is placed in a freely rotatable condition, and the transaxle 2 can be switched to the reverse speed change shift from a forward speed change shift.

摘要： PROBLEM TO BE SOLVED: To check falling-off by centrifugal force and vibration of a shock absorbing wave spring installed in a piston of a multiple disc type friction clutch. SOLUTION: A holding groove 31 is arranged in the piston 3 of the multiple disc type friction clutch, and the shock absorbing wave spring 6 is stored. An annular projection 32 having an inclined face 33 on an outer peripheral inner diameter surface, is formed in the holding groove 31. A cross section of the wave spring 6 is formed in a deformed line cross-sectional shape 64 having an inclined part 65 corresponding to the inclined face 33 on an outer diameter surface. Thus, even if the wave spring 6 tries to fall off from the holding groove 31 due to the centrifugal force and the vibration, falling-off from the holding groove 31 can be checked since the inclined faces 33 and 65 contact with reach other.

摘要： PURPOSE:To automatize the shift of power by providing a clutch-shoe receiving part by extending in the axial direction the cage of a cylindrical roller type two-way clutch having an arch-shaped cam surface, and by displacing the clutch shoe by a centrifugal force so that it can slide with an external member. CONSTITUTION:A cylindrical roller 30 is provided between a turning shaft 10 and a clutch outer-ring 20 to which power is transmitted, and is retained by a cage 40. The inner surface of the outer-ring 20 is made to be an arch- shaped cam surface, and the clutch connection is carried out by the wedge action with the roller 30. The cage 40 is extended in the axial direction to receive a clutch shoe 60 so as to be capable of being slid in the radial direction. The clutch shoe 60 is retained by a plate spring 70 and a guide plate 90. As the rotation of the outer-ring 20 and the cage 40 rises, the clutch shoe 60 is brought to slide with a fixed member 100 by a centrifugal force, and by the frictional force thus caused, it is given a torque in the reverse direction to move the cage 40 for producing the wedge action of the roller 30. By the movement of the cage, the changeover of the clutch can be automatically carried out.
