Abstract: A hydraulic control valve for an ATV or motorcycle takes hydraulic input from a hand brake lever as an input to a first cavity of the control valve with a movable piston therein, and from a foot brake lever as an input to a second cavity of the control valve with a movable piston therein, with the two pistons being linked. A bypass channel extends around the piston in the first cavity, which is closed off when the first piston moves longitudinally. The output of the first cavity hydraulically controls braking of the front wheel(s). The foot brake lever also pressurizes a direct line to brake the rear wheel(s) that doesn't go through the control valve.

Abstract: A modular cargo system for an off-road vehicle includes a triangular center case between a right side case and a left side case, each having a base attached downwardly to a platform on the vehicle while also defining a floor plane for resting on a flat floor surface. The side cases include non-parallel side walls, each defining an interior space large enough to hold a rider's helmet. Each case includes a handle on a hinged lid, enabling the side case to be carried with a single hand while the lid is closed. The hinge is on a leading side wall of the cases, latched on a trailing side wall of the cases, and clips to hold the side cases downward to the platform are on the trailing side walls.

Abstract: A hybrid power train structure for off-road vehicles (ATVs, UTVs and SSVs) uses an internal combustion engine (“ICE”) rotating a crankshaft through a continuously variable transmission (“CVT”) as a primary source of locomotion torque, but also includes a driving/generator motor which, in certain established conditions, can either provide an additional or alternative source of locomotion torque or can harvest electricity from the torque created by the internal combustion engine. The driving/generator motor is an axial flux motor of small size for its relative torque output, which can either be directly coupled to the CVT output shaft or, when additionally used as a starter motor for the ICE in an automatic ICE starting and stopping routine.

Abstract: An off-road vehicle includes a vehicle body, a power system, electrical devices, an electricity storage bank, a generator, and an electric power regulator. The electric power regulator is used to regulate the voltage output from the generator to the electricity storage bank and corresponds to the electricity storage bank. The electric power regulator includes a voltage regulating chip, a switch circuit and voltage stabilizing circuit. The electric power regulator is capable of regulating the voltage output from the generator to the electricity storage bank according to the nominal voltage of the electricity storage bank, and the output voltage of the electric power regulator is greater than the bank voltage.

Abstract: An actuator is used to longitudinally move a spline sleeve for controlling drive mode of a differential on an off-road vehicle. The actuator's motor rotates an eccentric knob through a drive train including intermediate gears and a worm gear. The eccentric knob is linked to the spline sleeve through a torsion spring carried on a pivot plate, with legs of the torsion spring pushing a slide block, transferring a moment provided by the eccentric knob into a linear slide force. The pivot plate and torsion spring are jointly mounted on the actuator housing by a hub, opposite the rotational axis of the eccentric knob from the slide block. The slide block includes a contact which completes a circuit through conductive pads on the actuator housing, so the position of the slide block can be directly sensed.

Abstract: A straddle-type vehicle (100) includes a frame (20) and an engine (10) mounted on the frame (20), the engine (10) includes a cylinder head (11) positioned toward the rear end of the frame, and located below a saddle seat (80). The cylinder head laces toward the rear end of the frame, which allows the heated cylinder head of the engine and the exhaust pipe connected to the cylinder head to avoid contact with the vehicle the user's legs while riding the vehicle, so the effect of heat emitted from the cylinder head on the rider's experience is reduced.

Abstract: A mechanical locking differential includes a driving ring in a differential housing between right and left active components. The driving ring is in line with the input bevel gear. The differential housing has a thin wall in a single, integral shell around the driving ring. Several hollow cylindrical shaft pins are used to attached the driving ring to the differential housing, with the shaft pins being driven radially relative to the transverse axis of the differential outputs in an interference fit with the housing and the driving ring. The shaft pins are held from axially backing out by two small rivets. The shaft pins preferably have a threaded inner diameter which assists in removal. The shaft pin attachment allows the bevel gear to extend closer to the transverse axis without obstruction.

Abstract: A mechanical locking differential includes a drive lock motor supported by the differential housing. The drive lock motor is disposed opposite the input bevel gear assembly, higher than the differential input and the differential outputs. The drive lock motor is coupled to a differential lock with a gear train that includes a worm drive, to output rotational motion on a lock output gear. The lock output gear causes sliding motion of a rack and a rack follower, pressing the differential lock into or out of engagement. The drive lock motor assembly is disposed fully between the right and left extents of the differential.
