ABSTRACT:
A brake support assembly for a vehicle including a stamped metal spider having a planar mounting portion and a pair of diametrically opposed support portions. A first support portion includes a first pair of ribs extending along opposite edges thereof as involuted ribs. A second support portion includes a second pair of ribs extending along opposite edges thereof to form flanges. A bracket extends across and connects the first pair of ribs. The bracket and the first support portion of the spider include laterally spaced apertures which receive press fit sleeve-type bushings. Anchor pins disposed in said sleeve-type bushings carry one end of a pair of brake shoes each comprised of a pair of spaced generally parallel webs secured to a table. The opposite end of the brake shoes is supported by cam follower rollers. Springs bias the brake shoes into contact with a cam actuator which may be rotated to displace the brake shoes. In the preferred embodiment of the present invention, the first pair of reinforcing ribs is terminated at a transition section extending from the planar first support portion as a rib of decreasing length to a total transition. The second pair of reinforcing ribs includes a termination section extending from the second support portion to the mounting portion as a flange having an orthogonally extending portion of decreasing length such that the termination section is completed when the radially extending portion of the flanges is coplanar to the plane of the mounting portion.
