Abstract: The object of this invention is directed to an improved control system and actuator for a transfer case. More particularly, this invention is directed to a hydraulic actuator and control system for a transfer case. One aspect of the present invention provides a hydraulic control system for a transfer case that includes an actuator for generating fluid pressure. The system also includes an isolation valve and a control valve in fluid communication with the actuator. The isolation valve is in a normally closed position and the control valve is in a normally open position. The system further includes a piston for applying fluid pressure to a device of the transfer case. The invention further provides a method for controlling the hydraulic pressure to a transfer case.

Abstract: An actuator assembly for a vehicle brake system comprises a piston disposed in a bore, a reservoir, and a solenoid. A channel is in fluid communication between the bore and the reservoir, and the solenoid is disposed in the channel. The solenoid is movable between an open position and a closed position. In the closed position, the solenoid blocks fluid communication between the bore and the reservoir.

Abstract: Brake assemblies and a method of dissipating heat from a brake assembly are provided. A first brake assembly includes a rotor, a brake caliper assembly including an actuator motor, and at least one friction pad operably attached to the caliper assembly. The actuator motor biases the friction pad into frictional engagement with the rotor. At least one thermal conduit extends distally from the actuator motor dissipating heat energy away from the actuator motor. The method includes providing an actuator motor and providing a thermal conduit extending distally from the actuator motor. Heat is conducted away from the actuator motor along the thermal conduit. A second brake assembly includes actuator motor means and thermal conduit means extending distally from the actuator motor means. The brake assembly further includes means for conducting heat from the actuator motor means along the thermal conduit means.

Abstract: The invention provides a brake caliper backdrive apparatus and method of backdriving a brake caliper. The apparatus includes a brake caliper, a motor including a shaft operably attached to the brake caliper and, a biasing member operably attached to the shaft. The biasing member backdrives the motor thereby releasing the brake caliper. The method includes rotating a shaft to clamp the brake caliper, storing energy in a biasing member responsive to the shaft rotation, and reversing the shaft rotation using the stored energy.
