Transmission clutch assembly
The present disclosure provides a transmission clutch assembly having a drum, a brake band, a smart material band and an electrical circuit. The brake band substantially encircles the drum and includes first and second ends, a high friction inner surface, and a low friction outer surface. The smart material band includes a beginning end and a terminating end wherein the beginning end of the smart material band is coupled to the second end of the brake band while the terminating end of the smart material band is coupled to the first end of the brake band. The electrical circuit transfers an electrical current to the smart material band. The smart material band contracts when the electrical current is applied to the smart material band thereby drawing the first and second ends of the brake band closer and contracting the brake hand against the drum to restrict drum movement.
