摘要:
In a transmission system for a small-size vehicle in which a crankshaft (2) of an engine (E) and an input shaft (10) of a multi-stage transmission (M) are connected to each other through a fluid transmitting device (T) including a pump impeller connected to the engine (E), and a turbine impeller connected to the transmission (M), a shifting clutch (Cc) is interposed between the crankshaft (2) of the engine (E) and the multi-stage transmission (M) in a series relation to the fluid transmitting device (T). Thus, a creep phenomenon of the fluid transmitting device (T) can be eliminated, and the shifting operation of the transmission (M) can be conducted lightly, by bringing the shifting clutch (Cc) into its OFF state.

In a transmission system for a small-size vehicle in which a crankshaft (2) of an engine and an input shaft of a multi-stage transmission are connected to each other through a fluid transmitting device (T), the fluid transmitting device (T) and a shifting clutch (Cc) are mounted on the crankshaft (2); one of them is connected to the crankshaft (2), while the other is connected the input shaft of the multi-stage transmission through a primary reducing device. Provided in the crankshaft (2) are an upstream supply oil passage (27A) connected to an oil pump (44), a downstream supply oil passage (27B) connected to portions to be lubricated of the engine, a flow-in bore (43B) which permits the upstream supply oil passage to communicate with the inside of the fluid transmitting device (T), and a flow-out bore (48) which permits the inside of the fluid transmitting device to communicate with the downstream supply oil passage. Thus, when the multi-stage transmission is to be shifted, a shifting operation can be conducted lightly, irrespective of a creep phenomenon of the fluid transmitting device (T) by bringing the shifting clutch (Cc) into its OFF state. Moreover, lubricating oil for the engine can be utilized to operate the fluid transmitting device (T) and hence, an exclusive oil pump (44) for the fluid transmitting device (T) is not required.

The invention relates to a rotary pump for use in particular in a continuously variable transmission. The rotary pump comprises a drive shaft (54) with a rotor (53), in radial grooves of which movable displacement elements (55) are disposed and slide along the radial inner side of a surrounding cam ring (56), forming variable pump chambers. The rotor is bounded at both long sides by end faces (57,58), an end plate (68) being provided with some play between at least one end face and the rotor. One or more seals (69) are provided between the end face (57) and the end plate (68), to seal the supply and/or discharge apertures of the pump in order to prevent leakages between the end plate and the end face.

摘要:
A power transmission system for a vehicle has a first power transmission path (4) having a forward-reverse shift mechanism (6) and a reduction gear (7), a second power transmission path (5) having an infinitely variable gear (9), and a path switching mechanism (8) which switches the power transmission path between the first and second power transmission paths according to the running condition of the vehicle. The infinitely variable gear is a toroidal speed change mechanism (90,91) having an output disk (900) fixed to the output shaft (7a) of the power transmission system, an input disk (901) which can be displaced in the axial direction of the output shaft and a roller (902) which is in contact with both the input and output disks to rotate about an axis in response to rotation of the input disk and transmit rotation of the input disk to the output disk, the transmission ratio of the toroidal speed change mechanism being changed by changing the inclination of the axis about which the roller rotates.
