A work vehicle includes a propelling device, which consists of a pair of right and left front wheels and a pair of right and left rear wheels, an engine configured to drive one of the pair of front wheels and the pair of rear wheels, an electric motor configured to drive the other of the pair of front wheels and the pair of rear wheels, a battery configured to supply electric power to the electric motor, and a controller configured to control the electric motor. The controller performs regeneration control at constant current value to charge the battery with regenerative power of the electric motor at a constant current value regardless of rotation speed of the electric motor.

A drive pulley for a continuously variable transmission (CVT) has a pulley shaft with a fixed sheave, a movable sheave and a back plate thereon. The movable sheave has a movable sheave surface with first and second surface portions that faces the back plate. A biasing member biases the sheaves away from each other. A slider is disposed between the back plate and the movable sheave. The slider has a flat engagement zone surface, and a curved driving zone surface extending outward from the engagement zone surface. From rest, as the pulley shaft accelerates, the engagement zone surface of the slider slides radially outward against the first portion of the movable sheave surface and then the driving zone surface of the slider slides radially outward against the second portion of the movable sheave thereby pushing the movable sheave toward the fixed sheave. A vehicle having the CVT is also disclosed.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.

A slip control method and arrangement for a drivetrain including a continuously variable transmission, forward-reverse clutch arrangement and an optional three-speed gearbox is described herein. The forward-reverse clutch arrangement includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. Accordingly, the clutch prevents the prime mover from stalling.

Provided is a continuously variable transmission, comprising an outer shell (1), wherein a middle shell (101) is provided in the middle of the outer shell (1), two sides of the middle shell (101) are respectively provided with a first end cover (102) and a second end cover (103), a third shaft (12) is arranged in the middle of the first end cover (102) in a penetrating manner, the third shaft (12) is connected to a bucket-wheel sun gear (501), the inside of the third shaft (12) is a hollow structure, a second shaft (11) is arranged in the middle of the second end cover (103) in a penetrating manner, the second shaft (11) is connected to a second sun gear (401), the middle of a first sun gear (301) is fixedly provided with a first shaft (10), the first shaft (10) passes through the third shaft (12), the inside of which is a hollow structure, in a penetrating manner, and the radius of rotation of a bucket-wheel planetary gear (502) rotating around the bucket-wheel sun gear (501) is greater than the radius of rotation of a second planetary gear (402) rotating around the second sun gear (401) and the radius of rotation of a first planetary gear (302) rotating around the first sun gear (301). The continuously variable transmission solves the technical problems of it being difficult, when a continuously variable transmission is applied to hybrid power transmission, to achieve arrangement in the same axis and complicated hybrid power assembly structure when a first shaft is connected to an engine or an output device and a third shaft is connected to an electric motor and can be widely applied to the field of transmission.

An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road vehicle.

A user input signal management method for a vehicle provided with a prime mover having an output that rotates and an input for a user input signal that controls the rotating speed of the output of the prime mover. The method including the reception of a signal representative of the position of a user input of a vehicle, the reception of data representative of at least one condition of the vehicle, the modification of the received signal representative of the position of the user input as a function of the data received and the supply of the modified signal to the accelerator input of the prime mover.

The present disclosure describes a powertrain and an all-terrain vehicle. The powertrain includes an engine, a continuously variable transmission and a transmission. The continuously variable transmission is drivingly coupled to the engine. The transmission includes a casing, a power input shaft, a first power output shaft and a second power output shaft. The power input shaft, the first power output shaft and the second power output shaft are all provided in the casing. The power input shaft is drivingly coupled to the continuously variable transmission, the power input shaft is drivingly coupled to the first power output shaft and the second power output shaft separately in the casing, and an axis of the power input shaft is parallel to an axis of the first power output shaft and perpendicular to an axis of the second power output shaft.

Clutch temperature management in a slip control method and arrangement for a drivetrain including a continuously variable transmission is described herein. The drivetrain includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. The temperature data from the clutch is used to determine the usable torque. Accordingly, the clutch prevents the prime mover from stalling.
