摘要:
A power unit for a saddle-ride vehicle includes a transmission mechanism disposed in the course of power transmission between a crankshaft and a drive wheel is installed in a crankcase, and a shift actuator to drive and control the gear-shifting action of the transmission mechanism is disposed in the engine main body. The shift actuator is attached to a side surface of the crankcase 35 while the operational axis of the shift actuator is placed in a plane that is orthogonal to the axial direction of a transmission mechanism. The shift actuator is disposed so that a high degree of freedom in the layout is guaranteed for the functional parts disposed around the crankcase. At the same time, the amount of outward protrusion from the crankcase is reduced and the maintenance work is made

摘要:
A transmission for a vehicle is provided which prevents generation of a speed change shock at the time of starting the vehicle from a neutral condition. In the transmission, hydraulic clutches are each put into a connected state according to an action of an oil pressure, and a plurality of selectively engageable speed-stage gear trains are provided so that a neutral condition can be obtained. At the time of shifting from the neutral condition, where the oil pressures in hydraulic clutches are in a lowered state, to a starting condition in which a starting gear train is engaged, pressure in the hydraulic clutch corresponding to the starting gear train is controlled by a control valve, so that the oil pressure in the hydraulic clutch is maintained in the lowered state during and immediately after a shifting operation, and is subsequently increased in response to complete engagement of the starting gear train.

A transmission M of a vehicular power transmission system has a first shifting part and a second shifting part which shift a power of an internal combustion engine, a first shift clutch transmitting and interrupting the power to the first shifting part, and a second shift clutch transmitting and interrupting the power to the second shifting part. A start clutch transmitting and interrupting the power to the first shift clutch and the second shift clutch is constructed of a centrifugal clutch C having a clutch shoe. The resulting configuration provides a vehicular power transmission system which has excellent efficiency of power transmission and durability, as well as being capable of being manufactured at low cost, and being capable of relieving a start shock.

A swash plate plunger type hydraulic motor is constituted such that plungers are slidably disposed in respective plunger holes of a motor cylinder, and a motor rolling member having a motor swash plate member is supported in a motor casing in such a manner that it can tilt and roll. A swash plate tilting angle detector for detecting the angle of a swash plate includes an angle detector mounted to a transmission housing and a rotation connection mechanism for connecting the motor rolling member to the angle detector. The rotation connection mechanism includes a first connection rod which is connected to the motor rolling member coaxially to its tilting and rolling axis, a second connection rod connected to the angle detector, and a movable or universal joint for connecting the first connection rod to the second connection rod. The described motor provides a swash plate tilting angle detector which has a high degree of freedom of installation position and permits the displacement of the center position thereof without affecting detection accuracy.
