ADAPTER PLATE FOR DISC BRAKE INSTALLATION

摘要

An adapter plate (42) for a caliper disc brake assembly is attached to the inboard side of the axle flange (18) of a vehicle axle housing. The adapter plate is generally C-shaped to allow mounting around the central region of the axle housing. The inboard positioning of the adapter plate allows mounting of larger brake calipers within a confined space. The caliper (52) is connected to the axle housing by the adapter plate for the purpose of positioning the caliper relative to the rotor and resisting the torque developed by the action of the brake pads on the rotor. In order to adjust the lateral position of the caliper, the adapter plate, in one embodiment, has a pilot surface (44) which allows the axle flange to be recessed within the adapter plate. In another embodiment, a secondary adapter plate (43) bridges over the opening in the adapter plate to allow mounting of the adapter assembly to the entire bolt circle of the axle flange.
