Methods and systems for operating a driveline that includes two electric machines are described. In one example, one electric machine is operated in a generator mode and the other electric machine is operated in a motor mode so that electric power that is generated by the electric machine that is operated in the generator mode is consumed by the electric machine that is operated in the motor mode.

Described is an electric telehandler (1) comprising: one or more traction apparatuses (3, 51, 6) equipped with a drive wheel (3); movement means comprising a plurality of hydraulic actuators, a hydraulic distributor (2) to actuate the actuators and a pump (21) for supplying the distributor (2); and an electric motor (4, 41, 42, 43, 44, 45, 46, 47, 48, 49) connected directly to the traction apparatus and/or to the pump (21) of the movement means.

A drive unit includes: a rotary electric machine; a rotary electric machine case accommodating the rotary electric machine; an electric power conversion device electrically connected to the rotary electric machine and configured to convert electric power supplied to the rotary electric machine and electric power supplied from the rotary electric machine; and an output shaft extending out from the rotary electric machine case and configured to output power of the rotary electric machine. The electric power conversion device is arranged on one side of the rotary electric machine. The output shaft is arranged between the rotary electric machine and the electric power conversion device.

The invention relates to a hydraulic device including: a stator and a rotor, in which the rotor can rotate relative to the stator about a first axis of rotation; and a shaft mounted on the rotor such as to rotate therewith. The shaft has a wheel carrier provided at a proximal end thereof and designed to receive a rim and a tire. The shaft includes a through-channel extending from the proximal end to an opposing distal end. The hydraulic device includes an air chamber formed at the distal end of the shaft and connected to the through-channel. The through-channel and air chamber are produced such as to allow a flow of air in order to control the pressure of a tire.

Provided is a vehicle power device including: an inner ring as a fixed ring, an outer ring as a rotary ring which is an outer ring rotation, and a bracket a knuckle for fixing an inboard side end portion of the inner ring removably with the electric motor disposed. The electric motor is of an outer rotor motor type, and the bracket includes a bracket base portion and a bracket cylindrical portion, the bracket base portion for being attached to the knuckle and fixed to the inner ring, the bracket cylindrical portion which extends from the bracket base portion toward an outboard side is located on an outer periphery of the outer ring via a radial gap and is provided with a stator disposed on an outer peripheral surface. The rotor of the electric motor is removably attached to the wheel mounting flange via a rotor casing.

A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

A land vehicle includes a frame structure, a plurality of wheels, and an impact management system. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The frame structure includes a pair of rails that each extends in the longitudinal direction from a first end arranged adjacent a pair of front wheels to a second end arranged adjacent a pair of rear wheels. The plurality of wheels are supported by the frame structure. The plurality of wheels includes the pair of front wheels and the pair of rear wheels. The pair of front wheels are positioned forward of the pair of rear wheels in the longitudinal direction.

Conventional axial flux motors typically include multiple rotors and stators resulting in a larger and heavier motor. Additionally, conventional axial flux motors include a housing to protect the rotors and stators, but the housing is often difficult to seal from the environment leading to risks of contaminants (e.g., dirt, water) infiltrating the motor and causing failure over time. The present invention overcomes these limitations by disclosing an axial flux motor with a single rotor and two stators. The use of a single rotor reduces the size and weight of the motor. An inboard housing and an outboard housing mechanically support the two stators and are joined together to define an interior cavity. A ring seal is disposed between the two housings to ensure the interior cavity is sealed. Additionally, the two stators may actuate multiple degrees of freedom (DOF) including the rotation of a wheel and actuation of a suspension.

Land vehicles and methods of operating land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels, and a plurality of electric motors. The frame structure includes a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction. The plurality of wheels are supported by the frame structure. The plurality of wheels includes a pair of front wheels and a pair of rear wheels positioned rearward of the pair of front wheels in the longitudinal direction.

A mobile body includes axial gap motors, a multiplexing mechanism, an abnormality detection mechanism, and a blocking mechanism. The axial gap motors generate driving power to be supplied to at least one wheel. The multiplexing mechanism multiplexes the axial gap motors and couples the axial gap motors to the at least one wheel of the mobile body. The abnormality detection mechanism detects an abnormality in the axial gap motors. In a case where the abnormality is detected in a certain axial gap motor of the multiplexed axial gap motors, the blocking mechanism blocks supplying of driving power from the certain axial gap motor independently of the multiplexed axial gap motors other than the certain axial gap motor, and maintains supplying of driving power to the at least one wheel from the multiplexed axial gap motors other than the certain axial gap motor.
