| 6932198 | Brake assembly and a method for braking a vehicle or another selectively movable assembly 25A brake assembly (10) which provides a controllably varying amount of self-energization by the dynamic adjustment of the position of a wedge member (22) which is based upon a measured amount of friction which exists between a pad assembly (14)... | 08/23/2005 |
| 6622833 | Drum brake system The invention relates to a drum brake device (10), which is provided as a wheel brake for a motor vehicle. The invention proposes embodying the drum brake device (10) with a brake belt (14), which is disposed inside a brake drum (12) and can flex in the r... | 09/23/2003 |
| 6491138 | Disc brake A disk brake having a self-energized brake effect. The disk brake has a sectional lining with a self-energized power brake and made up of a rotating brake disk, a U-shaped stationary caliper enclosing the brake disk from the outside, brake shoes disposed ... | 12/10/2002 |
| 6318513 | Electromechanical brake with self-energization An electromechanical brake, in particular for vehicles, has an electric actuator which generates an actuation force and acts on at least one frictional element so as to press the latter, in order to bring about a frictional force, against a rotatable comp... | 11/20/2001 |
| 6305506 | Braking system including motor-driven disc brake equipped with self-servo mechanism Electrically operated braking system with a motor-driven disc brake including an electric motor for braking an automotive vehicle wheel, and a motor control device controlling the electric motor, the disc brake further including a disc rotor having a fric... | 10/23/2001 |
| 5501303 | Single acting translational/rotational brake A brake system is provided that applies braking forces on surfaces in both the translational and rotational directions using a single acting self-contained actuator that travels with the translational mechanism. The brake engages a mechanical lock and cre... | 03/26/1996 |
