VEHICLE BRAKE, METHOD OF MEASURING BRAKE TORQUE AND BRAKE TORQUE METER

摘要

FIELD: mechanical engineering; transport vehicles brake systems. ^ SUBSTANCE: invention can be used in vehicle brake systems and also at designing of brake mechanisms. Proposed brake contains brake member made in form of drum or disk, drive and brake shoes with friction layer. Brake shoes are made in form of calipers with movable members carrying friction layer. Movable members are installed on calipers for limited displacement. Brake torque meter contains displacement pickup installed inside brake. Said displacement pickup is made in form of ring with inductive sensor. Ring engages by one side with movable member carrying friction layer and by other side, with caliper. Method of measuring of brake torque includes measuring of displacements or displacements or deformations of parts or units of brake appearing in process of braking and conversion of said displacements into electric signal proportional to brake torque. Displacement of movable member carrying friction layer is measured relative to caliper. ^ EFFECT: improved operating characteristics of brake, provision of self-alignment of shoes and uniform wear of friction surfaces, possibility of getting signal corresponding to actual brake torque implanted by wheel. ^ 4 cl, 8 dwg
