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 latching mechanism removably attaches an accessory to an offroad vehicle without requiring tools. The latching mechanism includes a body, a shaft extending through the body, and a handle riding on a conical surface of the body for rotating the shaft relative to the body. An oblong head extends on a lower side of the body, rotatable by the handle and shaft to a position where the head extends under a shoulder of a mounting recess. A spring system biases the head axially, such that the head can be moved either upwardly or downwardly from a balanced elevation set by a nut tightenable on a bolt. The mounting recess has an upper portion shaped differently from a lower portion. The body includes a hooking portion which extends significantly above the top of the mounting recess.

Abstract: A centralized control system in an information interaction system has a communication module capable of transmitting audio signals such as by Bluetooth with a first and a second wearable device. When a user of the first wearable device is on a driver's seat and a user of the second wearable device is on a passenger's seat of a vehicle the centralized control system is capable of transmitting audio signals for the driver and passenger to speak to each other. The information interaction system can include a display screen and/or button for connecting, or rejecting incoming, calls through a mobile terminal. The information interaction system can also have voice command recognition functions, such as to control certain equipment of the vehicle or to make and answer queries through the mobile terminal.

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: 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 eccentic 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 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: A power train component such as a gearbox includes driving and driven, coaxially arranged cooperating gears which engage each other via teeth. The engaging end surfaces of the teeth are provided with a first chamfer and a second chamfer, in which the chamfer edge is offset from bisecting the tooth. Preferably the offset chamfer edges are provided on both a driving gear (shifter), axially positionable using a shifting fork on a shift drum, and a driven low gear. In one preferred driving gear (shifter) design, the offset chamfer edges are only provided for the side engaged when the shifting fork moves against a spring force. The invention facilitates smoother and less binding movement between the non-engaged and the engaged axial positions, such that the gear can be more easily shifted by the shifting fork in at least one direction.

Abstract: A shift drum has a recess which controls a fork to move one of two cooperating coaxially arranged gears for transmitting torque in a power train of a vehicle. The recess includes a straight section, which upon rotation of the shift drum does not move the fork either to the left or the right, and at least one ramp which does move the fork in one direction (i.e., to the left or the right). The ramp is more complex than a single line, such as having a first portion at a first right-shift portion ramp angle ? and a second portion at a second right-shift portion ramp angle ?, perhaps with the intersection between the first right-shift portion ramp angle ? and the second right-shift portion ramp angle ? being at the mid-line defined by the straight section of the recess.

Abstract: An outer ring of an inner joint of the constant speed transmission shaft is provided with a vehicle speed sensor rotating synchronously with the inner joint, and the drive axle is fixedly equipped with a signal collecting device opposite to the vehicle speed sensor and configured to monitor a rotation speed signal of the vehicle speed sensor. The inner joint of the constant speed transmission shaft transmits torque during the running of a vehicle, and through monitoring a rotation speed of the inner joint, the rotation data of rear wheels can be obtained. By mounting the vehicle speed sensor on the inner joint and fixing the signal collecting device on the drive axle for monitoring the rotation speed signal of the vehicle speed sensor, the signal reading is stable, which facilitates the maintenance, reduces the cost, and can satisfy the environmental requirements.

Abstract: A constant velocity ball joint uses a star shaped sleeve with a splined connection to its shaft. The sleeve is longitudinally retained on its shaft using a retaining ring in an outwardly facing groove of the shaft. The star shaped sleeve has a 30° assembly assist chamfer angle on one side, as well as a 45° transition chamfer angle and a 65° ramp chamfer angle facing the opposite direction. These angles control the diameter of the retaining ring as it is compressed inward into the groove during assembly and disassembly. The star shaped sleeve can be used in a dynamic length CV joint, with the splines of a configuration that allows longitudinal sliding of the sleeve on the shaft, so the shell of the dynamic length CV joint still can be of the spherical race type.
