Embodiments relate to an off-road vehicle comprising a frame, including at a frame, a passenger compartment, a driveline that includes at least a drive system and a driven system, and a constant velocity (CV) joint for coupling the driven system to the drive system. The CV joint includes a housing, a coupling shaft, a detent, a plunge pin and an actuation pin, wherein the actuation pin has a first end that is accessible via an aperture in the housing, wherein actuation of the actuation pin determines whether the plunge pin is in the first position or the second position.

An off-road utility vehicle having a longitudinal centerline. The vehicle includes a frame, an oil pan, a prime mover coupled to the frame and a continuously variable transmission (CVT) cover assembly. The CVT cover assembly includes an inner CVT cover, an intermediate CVT cover, and an outer CVT cover. A drive clutch and a driven clutch are located between the outer CVT cover and the intermediate CVT cover. A flywheel is located between the prime mover and the inner CVT cover.

A powertrain for a snowmobile includes an engine, a gearbox input shaft and a drop case assembly receiving rotational energy from the gearbox input shaft. The drop case assembly is switchable between a forward mode and a reverse mode and includes an input gear assembly coupled to the gearbox input shaft. The input gear assembly includes a forward input pulley rotatably coupled to the gearbox input shaft, a reverse input gear rotatably coupled to the gearbox input shaft and an input selector collar between the forward input pulley and the reverse input gear. The input selector collar is slidable between a forward mode position engaged with the forward input pulley to transfer rotational energy from the gearbox input shaft to the forward input pulley and a reverse mode position engaged with the reverse input gear to transfer rotational energy from the gearbox input shaft to the reverse input gear.

A continuously variable transmission (CVT) drive clutch includes a stationary sheave and a stationary shaft coupled to the stationary sheave. A movable sheave is movable relative to the stationary sheave. The movable sheave includes a tower having a cavity therein. A cover is securable to the movable sheave via a fastener extending into the cavity of the tower. An elongate member is received within the cavity of the tower.

A torque control link for maintaining a stable center to center distance between a primary clutch and a secondary clutch of a continuously variable transmission of a snowmobile. The torque control link includes a root section, a tip section and a main body that extends between the root section and the tip section. The root section has a plurality of engine mounting features that couple to the engine and a crankshaft aperture that receives the crankshaft therethrough with a clearance therebetween. The tip section has at least one chassis mounting feature that couples to the chassis and a jackshaft aperture that rotatably supports a jackshaft therein via a bearing. The main body has a waveform cross section with a substantially uniform thickness that not only improves the manufacturability of torque control link but also improves the strength of torque control link.

An electrically variable transmission for an off-road vehicle including an internal combustion engine with a crankshaft. The electrically variable transmission includes a compound planetary gear assembly having a first planetary gear set with a first ring gear, a first sun gear and a first planet carrier and a second planetary gear set with a second ring gear, a second sun gear and a second planet carrier. The planet carriers are coupled together for common rotation and are coupled to an output gear for common rotation therewith. The first ring gear is in torque transferring communication with the crankshaft. The first sun gear is in torque transferring communication with a first motor generator. The second sun gear is in torque transferring communication with a second motor generator. The rotational axes of the compound planetary gear assembly and each of the motor generators are parallel rotational axes.
