摘要： In a V-belt continuously variable transmission (CVT) of an ATV, a movable sheave half of a primary sheave is disposed on the outer side in the vehicle width direction with respect to a fixed sheave half, and a sheave drive mechanism for controlling the respective groove widths of the primary sheave and a secondary sheave through a driving force by an electric motor is located on the outer side in the vehicle width direction with respect to the movable sheave half of the primary sheave. A footboard of the ATV is located on the outer side of the V-belt CVT in the vehicle width direction and below a primary sheave shaft and a secondary sheave shaft. A portion of the electric motor is located above and in front of the primary sheave shaft as viewed in the sheave shaft direction. A straddle-type vehicle having the compact, yet durable V-belt continuously variable transmission achieves a speed change operation highly responsive to the vehicle running condition.

摘要： A small vehicle has an engine mounted to a frame assembly. The engine is mounted by a plurality of engine mounts. The engine mounts are seven times stiffer in compression and tension than in shear. The engine mounts have a block of resilient material that separates a pair of plates. The block can be any shape but a rectangular parallelepiped is preferred. The engine mounts are mounted on cylinders defined with a center axis that extends through a center of gravity of the engine in a direction parallel to an axis about which the crankshaft rotates.

摘要： An off-road vehicle has front and rear wheels. An engine unit powers the wheels. The engine unit has an output shaft. A front differential is coupled with the front wheels. The front differential has a front input shaft. A front drive connects the output shaft and the front input shaft with each other. The front differential can operate in one of three modes: an unlocked mode, a locked mode and a disabled mode. A rear differential is coupled with the rear wheels. The rear differential mechanism has a rear input shaft. A rear drive connects the output shaft and the rear input shaft. The rear differential can operated in at least two modes: an unlocked mode and a locked mode. In one embodiment, the front differential is allowed to be locked only when the rear differential is locked.
