For internally-engaging brakes (F16D65/08)

Brake shoe and braking unit // 2628555
FIELD: automotive industry.SUBSTANCE: brake shoe contains the arc-shaped base, having the outer side in the radial direction to install the brake pad and the inner side in the radial direction, opposite to the outer side. Several loops are also formed at the base near its first end. The loops are aligned along the axis and located at the distance from each other along this axis. Each loop is configured in such a way, that it is possible to insert the fastening pin inside it, by means of which the brake shoe can be attached to the brake mounting support with ability to turn. The fastening pin is fixed in the first and the second loops to prevent its movement relative to these loops. The brake unit contains the mounting support, the brake shoes and the drive actuator. The actuator movement causes the movement of the first and the second brake shoes between the engagement position with the brakes working surface and the position, when it does not contact the working surface.EFFECT: stability of braking and steering dynamics.20 cl, 6 dwg
