FRICTION UNIT Russian patent published in 2005 - IPC

FIELD: mechanical engineering; friction units containing reinforcing metal framework, for example blocks for automobile disk brakes; friction units for various machines and mechanisms.

SUBSTANCE: proposed friction unit has metal framework with holes and friction member molded to it and provided with projections corresponding to holes in framework; projections are received by these holes. Novelty of invention consists in height of projections which is lesser than depth of holes; surface which is not brought in contact with framework inside holes has recesses in at least one of projections. Proposed friction unit enhances resistance of joint of framework with friction member to shear loads.

EFFECT: enhanced resistance to shear loads; reduced mass; low requirements for strength of composite material; facilitated procedure of manufacture.
