摘要： A vehicle suspension can include an adapter mounting face, a spindle rigidly mounted relative to the adapter mounting face, a wheel mounting hub including a hub body rotatably mounted on the spindle by bearings, and an adapter that spaces a brake component away from the adapter mounting face. Another vehicle suspension can include a spindle, bearings, and a wheel mounting hub rotatably mounted on the spindle by the bearings, the wheel mounting hub can include a hub body and a wheel mounting flange, the hub body and the wheel mounting flange being separate components of the wheel mounting hub. A system for adapting a vehicle suspension to different suspension capacities can include multiple wheel mounting hubs including a same hub body internal configuration configured to be rotatably mounted on the spindle by the bearings, but the wheel mounting hubs including respective different wheel mounting flanges.

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 steerable vehicle suspension can include an axle, at least one retractor having a length that decreases in response to a pressure increase applied to the retractor, and at least one wheel spindle. Resistance to rotation of the wheel spindle relative to the axle increases in response to the pressure increase applied to the retractor. A method of operating a steerable vehicle suspension of a vehicle can include allowing steering knuckles rotatably mounted at opposite ends of an axle to rotate relative to the axle while the vehicle moves forward, and applying an inwardly directed force simultaneously to each of the steering knuckles. Another steerable vehicle suspension can include two rotatably mounted steering knuckles, and two retractors connected to the steering knuckles. An inwardly directed force is applied by each retractor to a respective one of the steering knuckles in response to pressure applied to the retractors.

摘要： A damping convoluted air spring for use in vehicle axle/suspension systems includes a top plate, a bottom plate, and a bellows. The bellows includes a first lobe, a second lobe, and a third lobe operatively connected to one another. The first lobe being in fluid communication with the second lobe. The second lobe being in fluid communication with said third lobe. The first lobe operatively mounted on the top plate. The third lobe operatively mounted on the bottom plate. The second lobe includes a fixed volume under pressure to provide damping to the air spring during operation of the vehicle.

摘要： A tag axle suspension system provides weight reduction and enhanced safety and ride quality. In a described embodiment, a tag axle suspension system includes hanger brackets pivotably attached to a vehicle frame. Actuators push rearwardly on the hanger brackets to raise an axle relative to the vehicle frame. The hanger brackets are rigidly attached to a tubular member extending laterally across the vehicle frame. The tubular member is rotatably attached to the vehicle frame.

摘要： A tag axle suspension system can include a tire and at least one hanger bracket pivotable relative to a vehicle frame to deployed and lifted configurations. In the lifted configuration, the tire can be a lowest component of the suspension system, and can be a first component to engage a road surface. A tag axle suspension system can include an air spring and a travel limit device that limits compression of the air spring in a lifted configuration of a hanger bracket. A tag axle suspension system can include an axle, a suspension arm pivotably connected between a hanger bracket and the axle, and a travel limit device that limits displacement of the suspension arm in a lifted configuration of the hanger bracket. The travel limit device can limit displacement of the axle toward an air spring support in the lifted configuration of the hanger bracket.
