Abstract: A temperature regulation system for a vehicle includes a drive system configured to be coupled to an engine of the vehicle. The drive system is configured to convert power produced by the engine into electrical power for use by at least one traction motor of the vehicle. The system further includes a control unit for controlling the engine and drive system. The control unit is configured to automatically regulate a temperature of a vehicle component in dependence upon a detected reference temperature.

Abstract: A system includes a retarder in electrical communication through an electric link with an alternator, and a controller that compares a power measurement with an accessory load on a system during a retard event, and can reduce an electrical load on the alternator, or can remove all electrical loads from an engine, when electric power that is generated from the retarder is measured to be greater than an accessory load on the system. The system may include an alternator that provides a motor function to rotate a shaft coupled to an engine that is mechanically coupled to one or more mechanically drivable accessories. The alternator powers the mechanically drivable accessories in place of or in addition to the engine.

Abstract: Silencing equipment is provided for an air-cooling assembly in a large off-road vehicle having wheels, traction motors for the wheels that operate in a motoring mode to propel the vehicle and a power generating dynamic braking mode, resistor grids for dissipating the dynamic braking power, and a blower for moving cooling air past the grids to cool them. The silencing equipment may include a resistor grid housing 24 and at least one upper inlet 22 for passing cooling air to the interior of the housing. The inlet includes noise-absorbing material. A conduit 28 is provided for directing cooling air from the upper inlet through a transition chamber to reach the blower and at least one resistor grid in the housing. The conduit is lined with noise-absorbing material. A removable cover 30 is provided for the conduit for accessing the air blower in the housing through the transition chamber, whereby servicing of the blower may be performed without removal of the entire upper inlet.

Abstract: The present disclosure provides an electric motor for use in a vehicle. The disclosure includes a stator comprising a plurality of stator coils separated by the stator core. The stator coils have insulation thereon. The disclosure further includes an abrasion resistant layer covering at least a portion of the stator coil. The abrasion resistant layer is a porous material capable of resisting the abrasive effect of particulate matter within the air used to cool the motor.
