The disclosure is directed to an apparatus for generating energy in response to a vehicle wheel rotation. The apparatus may include a first roller comprising a curved roller surface configured to be positioned in substantial physical contact with a first wheel of the vehicle. The first roller may be configured to rotate in response to a rotation of the first wheel. The apparatus may further include a first shaft rotatably couplable to the first roller such that rotation of the first roller causes the first shaft to rotate. The apparatus may further include a first generator operably coupled to the first shaft. The generator may be configured to generate an electrical output based on the rotation of the first shaft and convey the electrical output to an energy storage device or to a motor of the vehicle that converts electrical energy to mechanical energy to rotate one or more wheels of the vehicle.

An axle assembly for an electric or hybrid vehicle includes electrically powered drive motors for respectively driving vehicle wheels. The axle assembly preferably includes a dual motor arrangement, wherein two electric motors are arranged end-to-end. Each motor includes an inverter that is directly connected to its respective motor, and includes a gearbox assembly coupled between an output of the motor and a corresponding constant-velocity (CV) joint operatively connected to a wheel. The inboard ends of the motors are secured to opposite faces of a cooling manifold wherein the cooling manifold maintains the motors in axial alignment. The cooling manifold plate is positioned between an inboard end of each of the motor housings, and the cooling manifold plate axially aligns the first and second motors. Further, each motor drives its respective gearbox assembly, which includes a gear reduction and clutch mechanism having a brake band assembly that is selectively operable to disconnect the respective motor from the vehicle wheel associated therewith.

A motor drive unit, in which an output end of a motor drive system using an electric motor as a power source and a rotator rotatably supported by a bearing unit are arranged side by side in an axial direction, and the output end of the motor drive system and the rotator are drivingly coupled in a relatively displaceable manner by a coupling member in which a plurality of couplers spaced apart in an axial direction are set. The bearing unit of the rotator is arranged such that a center of displacement of the rotator defined by the bearing unit is located between an arbitrary pair of couplers among the couplers.

A method, for a trailer brake control device of a vehicle trailer with an electric drive, includes receiving at least one acceleration request signal with a requested positive acceleration or a requested negative acceleration and further receiving a status signal with at least one status variable of the electric drive of the vehicle trailer. The method also includes generating, with a controller of the trailer brake control device, at least one brake actuation signal for at least one friction brake of the vehicle trailer and a torque request signal for the electric drive, each based on the at least one acceleration request signal and the status signal. Furthermore, the method includes outputting the brake actuation signal and the torque request signal via at least one output and/or at least one interface of the trailer brake control device.
