摘要： An arrangement for improving the cooling performance of an engine by suitably arranging an exhaust pipe and a valve mechanism with respect to the inclined direction of a cylinder block. A cylinder block is inclined in the rightward or leftward direction of a vehicle body, and an exhaust pipe and a valve mechanism are disposed along the inclined side wall of the cylinder block. The opposed side wall of the cylinder block, which has a large space in the vertical direction and exerts a large effect on the cooling performance of the engine, is less susceptible to thermal effects from the exhaust pipe and the valve mechanism, to thereby improve the cooling performance of the entire engine.

摘要： A shaft having a sprocket fixed at one end thereof is reliably assembled to the supporting wall of an engine, with a reduced number of parts and man-hours required for assembly. A camshaft having a sprocket fixed at one end thereof is installed by engaging a pair of ball bearings with supporting holes on supporting walls of the engine. A crescent-shaped step partially cut in the loosing direction of an endless chain is formed on one supporting hole. An outer race of one ball bearing on the camshaft is engaged with the step. An endless chain is wound around the sprocket, and the one ball bearing is moved into the supporting hole, and the other ball bearing is correctly engaged with the other supporting hole, thereby completing assembly of the camshaft.

摘要： In a power transmission path of a vehicle for traveling on uneven ground, a torque converter is provided so that torque transmission to a propeller shaft varies smoothly. Accordingly, it is difficult for the torque transmitted to the propeller shaft to exceed a tire slip limit. This arrangement suppresses slippage during traveling on uneven ground such as a muddy, marshy, sandy, snowy, or gravel road surfaces.

摘要： A casing of a power unit is formed which is capable of simultaneously driving the front and the rear wheels of a saddle type vehicle. The power unit includes an engine and a transmission in a compact construction. A crankshaft, a main shaft, a secondary shaft and an output shaft are supported in parallel to the longitudinal axis of the vehicle in a casing for both an engine and a transmission. The crankshaft, the main shaft and the secondary shaft are arranged on substantially the same level. The output shaft is disposed below the main shaft and the secondary shaft. The opposite ends of the output shaft project outside from the casing. The opposite ends of the output shaft are connected to a front driving shaft and a rear driving shaft, respectively.

摘要： In a power transmission apparatus for a vehicle having a gear transmission capable of transmitting power from a crankshaft of an engine to driving wheels by selectively establishing a plurality of shift stages of gear trains and a clutch for cutting power transmission from the crankshaft to the gear transmission in operating to shift the power transmission, when the clutch is operated to cut or connect in cooperation with the shift operation of the gear transmission, shift operability is promoted while avoiding an increase in weight. A gear transmission is shifted by a first actuator and a clutch is driven by a second actuator which is independent of the first actuator.

摘要： An improved transmission in a motor vehicle including a body, an engine located in the vicinity of the center of the body, a pair of footrests attached to the body near the engine, and front and rear wheels. The transmission is integral with the engine and has a casing, a shift spindle having one end projecting from the casing and rotatable for shifting the transmission, and a control lever coupled to the shift spindle. According to the improvement, a cam means is interposed between the control lever and the casing for limiting shifting operation of the control lever. The cam means comprises a cam member having a cam surface and fixed to the casing, a shaft member axially slidably fitted in the control lever and having a control knob on a first end thereof, and a spring disposed between the shaft member and the control lever for urging the shaft member to cause a second end of the shaft member to abut against the cam surface of the cam member. The cam means makes gear shifting operation more reliable and convenient.
