Integrated disc brake and drum rake construction

A disc brake, comprising a torque support member having receiving means, a piston housing having piston means disposed in a housing bore and the piston housing fixed to said support member, a yoke engaging on one side said piston means and on the other side a first brake pad, characterized in that the brake comprises rod means accepted in said receiving means and having an internal bore, the rod means extending within an opening in said piston housing, pin means attached at one end to said yoke and at the other end extending for slidable movement within said internal bore, the rod means permitting slidable movement of the yoke and pin means, the opening in said piston housing extending therethrough and the piston housing abutting a surface of said support member, the rod means secured to said support member, the pin means including thereabout a sleeve member received between the pin means and adjacent surface of the internal bore of the rod means, and the piston housing including aligned openings on opposte sides thereof, one aligned opening receiving means for securing said piston housing to the support member and the other aligned opening receiving means for securing flexible seal retaining means to the housing.

A support member connected with a vehicular axle and providing support for a disc brake, said support member extending radially outwardly and having openings therein, the disc brake having a piston housing fixed to said support member by securement means extending through associated openings in said support member, characterized in that the piston housing has at least one through opening receiving therein rod means, the rod means secured at one end to said support member and the other end having a bore extending therein, the disc brake comprising an axially movable yoke member having pin means affixed thereto and extending into said bore for slidable movement relative to said rod means, the support member including a second part, the openings in the support member including respective aligned openings in said second part and receiving therein the securement means, the second part fixed securely to the support member by means of the rod means and securement means, and the second part of the support member extending axially to provide an anchor support for brake shoes of a drum brake disposed about said axle, the brake shoes positioned for engagement with an axially extending circular portion of a disc of said disc brake.

A disc brake, comprising a torque support member having receiving means, a piston housing having piston means disposed in a housing bore and the piston housing fixed to said support member, a yoke engaging on one side said piston means and on the other side a first brake pad, characterized in that the brake comprises rod means accepted by said receiving means and having an internal bore, the rod means connected with an anchor support which extends axially to provide anchoring support for brake shoes of a drum brake, the brake shoes positioned for engagement with an axially extending circular portion of a disc of said disc brake, and load bearing pin means attached at one end to said yoke and at the other end extending for slidable movement within said internal bore, the rod means permitting slidable movement of said yoke and pin means, and the pin means transmitting braking torque to the rod means and support member.

A support member connected with a vehicular axle and providing support for a disc brake, said support member extending radially outwardly and having openings therein, the disc brake having a piston housing fixed against axial and radial movement to said support member by securement means extending through associated openings in said support member, characterized in that the piston housing has at least one through opening receiving therein rod means, the rod means secured at one end to said support member and the other end having a bore extending therein, and the disc brake comprising an axially movable yoke member having load bearing pin means affixed thereto and extending into said bore for slidable movement relative to said rod means, braking torque transmitted through the pin means to the rod means, housing, and support member.
