BRAKE UNIT, COMPONENT OF EMERGENCY BRAKING SYSTEM AND PROCEDURE FOR ACTUATION OF BRAKE UNIT Russian patent published in 2010 - IPC F16D65/04 

FIELD: machine building.

SUBSTANCE: brake unit consists of rotating element and non-rotating brake component. The brake component consists of a rigid plate of the base, of an erasable friction material and of lugs projecting from the support plate in a layer of friction material. Each of lugs has an end in direct vicinity from surface of friction material. The ends of the lugs and external surface are simultaneously interact with contact surface of the rotating element, when the brake component transits into a position of braking for the first time. Friction material and the lugs together create friction force actuating the rotating element at the first contact between their surfaces. The procedure for actuation of the brake unit consists in driving the rotating element, in assembling the brake component in direct vicinity from the rotating element at a certain distance from contact surface, in actuating the brake component and in creating friction by bringing the ends of the lugs and external surface of friction material with contact surface of the rotating element into interaction. Thus friction material and the lugs facilitate generation of required friction force at the first interaction of their surfaces with contact surface of the rotating element.

EFFECT: increased efficiency of brake unit, and improved static and dynamic properties of brake unit friction at its first actuation.
