ANCHOR ARRANGEMENT FOR RETAINING A SENSOR IN A DRUM BRAKE

摘要

The anchor arrangement (24) of a drum brake (10) includes a load sensor for measuring a torque generated between the first (14) and second (16) brake shoes and the drum (18). The anchor arrangement (24) has a bracket (44) with a base (46) having first (48) and second (50) side walls which are secured to the backing plate (20). A core member (64) of the load sensor is retained by the bracket (44) between the first (48) and second (50) side walls and is connected to a controller (28). Linkages (66, 74) extend through openings (56, 58) in the side walls (48, 50) for connecting the brake shoes (14, 16) to the core member (64). The first (14) and second (16) brake shoes on engagement with the drum (18) define a leading and a trailing brake shoe. The leading brake shoe produces a force which moves the core member (64) into engagement with the bracket (44) to compress the core member (64) and independently modify an output signal generated therein to define an operational torque developed during a brake application.
