An energy efficient vehicle and a disc-type dynamic motor thereof are disclosed. The vehicle comprises front wheels and rear wheels, and a gasoline engine is assembled in the vehicle for driving a generator producing power. The power is transported to a capacitor battery via a circuit control system and then to disc-type dynamic motors, which are assembled with the rear wheels, from the capacitor battery via two power lines respectively, whereby the disc-type dynamic motors directly driving the vehicle travelling at high-speed and high torque via the wheels. Accordingly, the energy efficient vehicle does not include transmission devices, such as the clutch, the transmission, the power transmission shaft, and the differential. The power produced by the generator is directly provided to the disc-type dynamic motors to drive the vehicle travelling and is enough to drive the disc-type dynamic motors, so the vehicle does not need to stop for charging.

A method for damping juddering in the drive train of a vehicle having an electric motor as the drive motor, and a vehicle having a closed-loop control system to carry out the method. The method includes calculating an electric motor setpoint torque for actuating the electric motor from an electric motor request torque which corresponds to a current request for a torque, and calculating a correction torque as a function of the electric motor request torque and a correction factor which is determined from a rotational speed of the electric motor.

An axle drive for a vehicle comprising at least one drivable vehicle axle comprises a drive shaft that extends along a longitudinal direction of the vehicle, starting from a first side of the axle drive, to a second side of the axle drive and that is configured to receive drive power from an electric motor arranged at the first side and to output said drive power at the second side to a driven shaft that extends at the second side of the axle drive offset from the drive shaft and that is configured to output drive power to the vehicle axle via a bevel gear facing towards the first side. The axle drive further comprises a brake, in particular a parking brake, comprising a brake disk that is arranged at the second side of the axle drive, in a manner facing away from the first side, at the drive shaft or at the driven shaft.

A multi-purpose utility vehicle for construction and snow-removing work includes: a cargo box seated on a loading frame in the rear part of the vehicle; a continuously variable transmission combination mounted in a mounting space partitioned by a midship frame in the middle of a vehicle body; an engine assembly mounted in an engine room partitioned by a loading frame and base frames of the vehicle body at the back of the midship frame; a front wheel propeller shaft and a rear wheel propeller shaft which respectively transfer driving power outputted from the continuously variable transmission combination to a front axle combination of a front end of the vehicle body and a rear axle combination of a rear end of the vehicle body; and a PTO electromotive system extending from the front of the continuously variable transmission combination to the front of the vehicle body.

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 recreational off-highway vehicle includes side-by-side passenger and driver seats held within a chassis that is approximately 50 inches wide. The seats sit low in the chassis and are covered by a roll cage. Grab handles are positioned on the sides of the passenger seat. Select large round tubing protects the vehicle, while rectangular tubing frames the portions of the vehicle beneath body panels. The vehicle is powered by an engine rearward of the seats that is connected to a transaxle. The engine and transaxle are isolation mounted together with a portion of the air intake assembly. The vehicle is suited for rough terrain travel.
