Abstract: An axle assembly for a vehicle includes a frame, a motor, and a pair of gear reduction subassemblies. The frame extends between a first distal end and a second distal end. The second distal end opposes the first distal end. The motor is secured to the frame between the first distal end and the second distal end. The pair of gear reduction subassemblies are rotatably coupled to the first distal end and the second distal end and configured to drive rotation from the motor to a pair of wheels. Each gear reduction subassembly includes a plurality of gears defining a plurality of gear ratios.

Abstract: A vehicle frame assembly includes a plurality of members, a tray, at least one insulation member, and at least one battery. The plurality of members define a first void. The tray is coupled to at least one member of the plurality of members. The tray defines a second void. The at least one insulation member is disposed within the first void or the second void. The at least one battery is disposed within the first void and the second void.

Abstract: A system includes data processing hardware and memory hardware. The memory hardware is in communication with the data processing hardware and stores instructions that when executed on the data processing hardware cause the data processing hardware to perform certain operations. The operations include receiving a temperature corresponding to a battery, and determining whether the temperature is greater than a predetermined threshold temperature. The operations also include, when the temperature is greater than the predetermined threshold temperature, actuating an ejector to eject the battery from a power supply assembly.

Abstract: 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.
