A rear wheel driving device includes first and second electric motors, a wet multi-plate type hydraulic brake provided on motive power transmission paths between the first and second electric motors and rear wheels Wr and causing the drive source side and the wheel side to become disconnected state or connected state by being released or fastened, and a control device that controls switching between the disconnected state and the connected state of the hydraulic brake and controls a vehicle speed. The rear wheel driving device further includes a viscosity acquisition unit that acquires a viscosity correlation amount of oil provided to cool plates of the wet multi-plate type hydraulic brake, and the control device fastens the hydraulic brake or maintains fastening thereof and controls the vehicle speed to lower than a first speed in a case where the viscosity correlation amount is a first prescribed value or higher.

Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.

An electrically driven axle with electrical drive units (4) arranged symmetrically around the axle body (1). The drive units having an electric machine and a transmission, and at least one spring-loaded brake (3) as a parking brake. The spring-loaded brakes (3) are arranged radially, thus enabling the spring-loaded brake (3) to be released by removing a release spindle (7) from brake cylinders of the spring-loaded brakes (3).

A gearbox attachment of a wheel drive unit A-shield assembly for an electric vehicle four motor powertrain system is disclosed. The gearbox attachment includes a housing, a gear reduction assembly, and an actuator assembly. The housing is adapted to fasten to an A-shield of the wheel drive unit A-shield assembly. The housing includes an outer ring. The gear reduction assembly is at least partially received in the outer ring. The gear reduction assembly is adapted to receive an output of a gearbox of the wheel drive unit A-shield assembly that is adapted to provide an output of a motor to a single wheel of the electric vehicle. The gear reduction assembly is adapted to provide a gear reduction for a higher torque and slower speed in a gear reduction mode. The actuator assembly adapted to actuate the gear reduction assembly output between the gear reduction mode and a standard mode.

A portal axle arrangement 1 for a motor vehicle includes at least one portal housing 2 and at least one suspension arm 5, 6. The at least one portal housing 2 includes a receiving section 7 for a portal gear and at least one connecting section 8, 9 for the at least one suspension arm 5, 6, in which the at least one connecting section 8, 9 is designed as a support section. A motor vehicle including such a portal axle arrangement is also provided.

A vehicle drive system for an electric vehicle having in-hub motors configured to be independently controlled from the main traction motors. The configuration allows for robust control of the vehicle dynamics and behavior by allowing an improved powertrain control. The system also allows the vehicle to achieve better efficiencies.

A main body frame (100) for an electric motorcycle comprises a front fork support member (101) with a front fork through hole for loading a pivot stem of a front fork (200), the front fork through hole has a pivotal axis arranged in a central plane (P) of the main body frame; the main body frame further comprises a right and a left frame part (102, 105) arranged on opposite sides of the central plane of the main body frame, each having an elongated shape and being formed of an upper part (102a, 102b) and a lower part (102c, 102d), respectively at different sides of an elongation direction changing portion (102e), a first buffer member (120) attached, at opposite sides thereof, to the right and the left frame part, and crossing the central plane. wherein starting from the respective elongation direction changing portions thereof. the upper parts of the left and the right frame part extend inwardly towards the central plane so as to embrace the front fork support member, and are attached to opposite sides of the front fork support member, and a largest width (a7) of the main body frame in a width direction (Z) perpendicular to the central plane is 10 cm or more and 30 cm or less.

This disclosure details electrified vehicle drive systems equipped with electric machine integrated axle assemblies. An exemplary electrified vehicle drive system includes a leaf spring assembly and an axle assembly mounted to the leaf spring assembly. The axle assembly may include a cradle and an electric machine mounted within the cradle. Shocks and stabilizer bar assemblies may extend between the cradle and a vehicle frame of the electrified vehicle.

A motor gearbox assembly is provided for a vehicle having two wheels on opposite sides of the vehicle. The assembly includes two independent drive systems that each include an electric motor and an associated gear train, each drive system being configured to independently drive one of the wheels. The assembly further includes a common housing that receives the motors and the gear trains such that the gear trains are at least partially positioned between the motors. Furthermore, at least portions of the drive systems have generally inverse orientations in a longitudinal direction of the vehicle when the motor gearbox assembly is mounted on the vehicle.

A utility task vehicle (UTV) includes a frame having frame rails and a battery assembly positioned laterally between the frame rails. The battery assembly includes a battery housing and a battery array having a plurality of battery cells. The battery array is positioned within the battery housing and the battery assembly provides support for or is located under a floor of a cabin of the utility task vehicle.
