CLASP BRAKE AND SPREADER BAR Russian patent published in 2009 - IPC F16D65/12 F16D55/36 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to clasp brakes. The propose clasp brake incorporates a caliper enveloping one or more brake plates, a hub or a part linked up wit the hub. Spreader bars are arranged between the brake disk and hub or the part linked up wit the hub. The spreader bars are arranged to prevent contact between brake plate spline end faces and the hub spline end faces, or the part jointed to the hub, at whatever radial shift of the brake plate relative to the hub or the part jointed thereto. At least, one part of the spreader bar features such sizes and rigidity relative to the brake plate, hub or part splines that, at whatever radial shifts of the brake plate to the hub or part jointed thereto, all radial forces are transmitted from the brake plate to the hub or the part jointed to it only via, at least, one part of the spreader bar. The sizes are selected so as to provide a contact between the brake plate spline end faces those of the hub or the part jointed thereto in rotary engagement between the brake plate and hub or the part jointed thereto to transmit rotary motion in braking.

EFFECT: damping radial impacts or radial shifts between brake plate and hub, particularly, between end faces of appropriate splines.
