An off-road vehicle is disclosed which comprises a driveline assembly unit operative Iy connecting the propeller shaft to the front or rear wheel assemblies. The driveline assembly unit includes a main housing, a slip clutch torque limiting mechanism, and a wet brake clutch assembly. The slip clutch torque limiting mechanism and the wet brake clutch assembly being housed within the main housing and are coaxial with the propeller shaft of the off-road vehicle. A driveline unit is also disclosed that combines torque limiting and brake functions.

Driveline for off-road vehicle

An all-terrain vehicle (ATV) has a subtransmission detachably fastened to an engine casing. The engine crankshaft includes a drive pulley connected via a belt to a driven pulley in the subtransmission, thus providing a continuously variable transmission (CVT) between the engine crankshaft and the subtransmission. The subtransmission includes a 2WD-4WD selector mechanism to select two-wheel-drive or four-wheel-drive and also includes a transmission selector mechanism to put the vehicle in park, neutral, reverse, high-speed drive or low-speed drive. By disposing these selector mechanisms in the subtransmission, mass centralization is improved relative to prior-art drivetrains wherein the 2WD-4WD selector mechanism connects to the front differential. When operating in 2WD mode, the drivetrain does not waste energy rotating the front drive shaft, as in the prior art.
