    摘要： A suspension system can include an air spring, an air reservoir external to the air spring, and a flow control device which variably restricts flow of air between the air spring and the air reservoir. Flow between the air spring and the air reservoir may be permitted in response to compliance of the suspension system, and the air spring can have an internal air volume at least 2½ times as great may permit flow between the air spring and the air reservoir in response to a predetermined pressure differential level across the flow control device. Multiple air reservoirs can be internal to an axle, or other suspension system or vehicle component, and can be isolated from each other.

    摘要： A bushing for use in an axle/suspension system of a heavy-duty vehicle. A beam supports an axle for pivotal movement with a hanger of the heavy-duty vehicle at a pivot connection. A bumper is fixed to the beam and contacts an engagement member of the heavy-duty vehicle to limit the relative pivotal movement of the beam and axle in one direction. A force is applied to the pivot connection in a force application direction that is angularly spaced from horizontal and vertical planes. The pivot connection includes a bushing to connect the beam and the hanger. The bushing includes an elastomeric bushing body with at least one void for decreasing rigidity of the bushing body in a substantially vertical direction. The one void is located in the bushing body angularly spaced from the force application direction. The bushing body is substantially solid along the force application direction.

    摘要： 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.
