Abstract
A brake lining of a vehicular brake device is produced by a friction material which has a characteristic that a friction coefficient of the friction material decreases according to an increase of a sliding speed between the brake lining and a rotational member when the sliding speed is greater than or equal to a predetermined speed during the braking operation, and the friction coefficient is substantially constant when the sliding speed is smaller than the predetermined speed.
Claims8
A brake lining of a vehicular brake device, the brake device executing a braking operation by forcing the brake lining into friction contact with a rotational member, the brake lining comprising:
- a friction material having a characteristic that a friction coefficient of the friction material decreases according to an increase of a sliding speed between the brake lining and the rotational member when the sliding speed is greater than or equal to a predetermined speed during the braking operation, and the friction coefficient is substantially constant when the sliding speed is smaller than the predetermined speed wherein the predetermined speed is a speed at which a self-excited vibration of the brake device is generated.
A disc brake of a vehicle, comprising:
- a disc rotor;
- and
- a pair of bake pads forced into friction contact with the disc rotor, the brake pads being constructed by a friction material which has a characteristic that a friction coefficient of the friction material decreases according to an increase of a sliding speed between the brake pads and the rotor when a sliding speed is greater than or equal to a predetermined speed during a braking operation, and the friction coefficient is substantially constant when the sliding speed is smaller than the predetermined speed wherein the predetermined speed is a speed at which a self-excited vibration of the brake device is generated.
