Abstract
A drum brake arrangement for vehicle axles has an axle body and a support plate connected thereto. A bearing lever is fixed to the support plate. A brake camshaft has a first and a second end and is actuatable by a brake cylinder. The brake camshaft has a brake cam connected to the first end. A support bearing and another bearing for rotatably supporting the brake cam shaft on the axle body are provided. A slack adjuster is connected to the second end of the brake camshaft and has a housing with a cylindrical bore. The slack adjuster has a worm gear, connected to the brake camshaft, for adjusting the drum brake according to wear of the brake pads. The worm gear has a first profiled section extending parallel to its axis. The brake camshaft has a second profiled section extending parallel to its axis. The first and second profiled sections mesh with one another for fastening the worm gear on the brake camshaft. The slack adjuster has a bearing ring supported in the housing for receiving the bearing lever. The bearing ring has an outer mantle surface and is connected to the bearing lever. The worm gear has an outer mantle surface resting on a cylindrical inner surface of the cylindrical housing bore. The outer mantle surface of the worm gear and the bearing ring together constitute the bearing.
