A suspension assembly for a heavy-duty vehicle axle/suspension system that includes a geometry that enables components of a brake system to be mounted above and be protected by a beam of the suspension assembly. In an embodiment of the suspension assembly, the beam includes a recessed area that allows a brake actuator to be positioned at least partially within or disposed adjacent the recessed area.

Suspension assembly with disc brake actuator protection

An axle/suspension assembly for a heavy-duty vehicle supported by a frame and a hanger includes a beam, an axle, and a bumper. The axle is supported by a first portion of the beam for pivotal movement of the beam relative to the hanger at a pivot joint. The first portion of the beam is located on a first side of the pivot joint. The bumper is fixed to at least one of the frame, the hanger, and a second portion of the beam. The second portion of the beam is located on an opposite second side of the pivot joint. The bumper includes a portion for contacting structure of at least another of the frame, the hanger, and the beam to limit pivotal movement of the axle in one direction.

Axle/suspension system with down stop

A heavy-duty vehicle brake hardware mounting component that includes an integrated axle vent system and optional air supply line connector. The brake hardware mounting component includes a body with a central opening disposed around and rigidly attached to an axle of the vehicle. An annular groove is formed within the central opening and is in fluid communication with an axle opening. The air supply line connector is attached within an opening formed in the body and extends through the groove and into the axle opening, and enables attachment of and fluid communication between components of a tire inflation system within the axle and an external air source. Pressurized air from within the axle can flow through the axle opening, around the air supply line connector, through the annular groove, through a check valve in fluid communication with the groove, and to atmosphere to relieve air pressure build-up within the axle.

Brake mounting hardware with integrated axle vent system

An air disc brake system for a heavy-duty vehicle comprising an axle. A spindle is attached to an end portion of the axle. At least a portion of an air disc brake assembly is supported by the spindle. A suspension beam has an axle support portion connectable with the axle. An end portion of the suspension beam is spaced from the axle support portion for attachment with the heavy-duty vehicle. The suspension beam may pivot about the end portion of the suspension beam. An actuator actuates the air disc brake assembly. The actuator has a movable member to actuate the air disc brake assembly. Structure is associated with the suspension beam for supporting at least a portion of the actuator. A surface defines an opening in the suspension beam through which the movable member may extend or that may receive and support a portion of the actuator.
