摘要： A clutch hydraulic pressure control circuit includes: a shift valve for switching the destination to feed hydraulic pressure to a first hydraulic clutch or a second hydraulic clutch; and first and second shift solenoid valves operating synchronously to actuate the shift valve. The two shift solenoid valves include a holding valve for keeping hydraulic pressure fed to the shift valve even when hydraulic pressure supply through one of the first and second shift solenoid valves happens to be shut off while hydraulic pressure is fed through the first and second shift solenoid valves to paths between the shift valve and the shift solenoid valves, or when hydraulic pressure supply through one of the first and second shift solenoid valves happens to occur while no hydraulic pressure is fed through the shift solenoid valves.

摘要： A drum type-variable speed drive wherein a spring bearing member, which is restricted from moving in the axial direction of departing from a shift fork by a locking member fixed to a shift fork shaft, is pivotally supported by the shift fork shaft. A lost motion spring is interposed between the spring bearing member and the shift fork. Movement of the shift fork shaft in the axial direction caused by rotation of a shift drum presses the spring bearing member through the locking member, whereby the spring load of the lost motion spring acts on the shift fork.

摘要： A power unit includes a transmission adapted to transmit rotational power from a crankshaft to a drive axle, with speed change. The transmission has an input shaft rotatably supported on a crankcase. A hydraulic clutch, configured to be selectively engaged and disengaged, is disposed coaxially with the input shaft. A clutch cover covering the hydraulic clutch is connected to the crankcase. A clutch actuator, which controls switching between engagement and disengagement of the hydraulic clutch, and an actuator cover, which covers the clutch actuator in a liquid-tight manner, are mounted to an outer surface of the clutch cover. An oil temperature sensor is mounted to the actuator cover, and is provided for detecting a temperature of oil in an oil chamber, formed between the clutch cover and the actuator cover.
