Abstract: A brake cooling system uses a pair of subsystems to efficiently provide brake cooling and operation of the system. A first subsystem uses an axle assembly to drive one or more pumps to drive a variable speed cooling flow pump motor and a variable speed fan motor. A second subsystem includes one or more cooling flow pumps that are driven by variable speed cooling flow pump motor to supply a cooling fluid to an air-fluid heat exchanger for cooling and then supply the cooled fluid from the heat exchanger to brakes of the axle assembly. The variable speed fan motor drives a fan for the air-fluid heat exchanger for cooling of fluid passing therethrough. The system also includes a means for controlling the speed of the motors to regulate the heat exchanger operation and cooling flow through the heat exchanger and brakes of the axle assembly.

Abstract: A brake release system for a vehicle is described to transfer mechanical movement between two hydraulic actuators. The system includes a first hydraulic system on a removable portion of the vehicle and a second hydraulic system on a main chassis of the vehicle. The two hydraulic systems are mechanically engaged with each other where the removable portion of the vehicle attaches to the main chassis. In this way, a force applied to the removable portion of the vehicle when the vehicle's tow hook is engaged may be transferred to release the parking brake on the main chassis without a hydraulic connection between the removable portion and the main chassis. This may be useful when a removable battery frame with a tow hook makes up a separable rear portion of an electric vehicle, allowing the battery frame to be quickly and efficiently removed from the main chassis of the vehicle.
