摘要： A vehicle power transmission apparatus is provided for maintaining a constant power output when driving a vehicle regardless of the change in the frictional force of the belt in a belt type stepless speed change device. A belt type stepless speed change device is used with a vehicle driving, prime motor on board a vehicle. The apparatus provides a flat characteristic segment covering at least a part of the power output characteristic relative to the revolutions of the vehicle driving prime motor. The apparatus allows the vehicle to be driven by a constant power output within the segment of the flat power output characteristic regardless of changes in the frictional force of the belt in the belt type stepless speed change device.

摘要： A four-wheel buggy with a riding saddle seat includes a vehicle frame, a pair of front wheels and a pair of rear wheels rotatably suspended from the vehicle frame and projecting laterally from the vehicle frame. An air-cooled engine is mounted on the vehicle frame substantially centrally in the longitudinal direction of the vehicle frame. The four-wheel buggy also includes a pair of foot steps, a driver's seat mounted on an upper portion of the vehicle frame and supported by the vehicle frame, a handlebar operatively connected to the vehicle frame for steering the front wheels, and a body cover attached to the vehicle frame. The four-wheel buggy further includes a cooling fan unit mounted on the vehicle frame and including a fan and a drive unit for rotating the fan, and a control system for controlling the drive unit. The cooling fan unit is disposed in front of the engine for directing air from the cooling fan unit toward the engine. The four-wheel buggy has sufficient engine cooling performance while it runs at low speeds.
