DISC BRAKE HAVING PROTECTION AGAINST BEING INSTALLED IN WRONG POSITION OF BRAKE SHOES Russian patent published in 2013 - IPC F16D65/92 

FIELD: machine building.

SUBSTANCE: disc brake includes a brake shoe holder, two brake shoes, a brake support and positioning devices on both sides of the central plane of the brake. Positioning devices are located asymmetrically relative to central plane of the brake. As per the first version, positioning devices include a cavity on the support or a projection on the support, which are located on each side of the disc. As per the second version, positioning devices include a combination of a slot and a projection between the support and the brake shoes; centre of the combination of the projection and the cavity of inside brake shoe and the support lies on opposite side of central plane of the brake in relation to the centre of combination of the projection and the cavity of outside brake shoe and the support. As per the third version, positioning devices include a cavity or a projection on the brake support or brake shoes so that the cavity or the projection passes in inclined plane relative to central plane of the brake. As per the first version, brake shoes for the disc brake are provided on their support plates for linings with projections or cavities, which are located asymmetrically relative to central plane of the brake. As per the second version, brake shoes for the disc brake are made so that each brake shoe includes a projection or a cavity. The projection or the cavity on one brake shoe is located asymmetrically relative to central plane of the brake and offset to one side of the above central plane while the projection or the cavity on the other brake shoe is located asymmetrically relative to central plane of the brake and offset to the other side of the central plane.

EFFECT: providing correct installation of shoes under any operating conditions and providing uniform wear of a brake without any brake vibrations.
