ABSTRACT:
A torque plate construction (50) comprises two stamped parts (58, 60) which are fastened together at central planar portions (62, 63) thereof and to a wheel axle housing (20) of a vehicle. Each torque plate part (58, 60) includes housing portions (77) spaced axially from the central planar portion (62, 63) of the respective plate part, the portions (77) providing a wheel cylinder housing (78). A piston cylinder (90) is disposed within the wheel cylinder housing (78), with a pair of bolts (100) and nuts (87) connecting together the portions (77) and securing the cylinder (90) within the housing (78). Each torque plate part (58, 60) has a pair of circumferentially spaced-apart notched portions (37) providing seats for a pin (40) extending from an associated brake shoe web (34), one web having an extension (39) extending between the torque plate parts to engage the piston (92). During braking application, torque is transferred by a web pin (40) to a pair of notched portions (37) and through the wheel cylinder housing (78) and bolts (100) to the central planar portions (62, 63) of the torque plate (50).
