Abstract
An adjustable limit bar assembly for a suspension system includes an elongated member having a longitudinal axis and an attachment mechanism disposed on an end of the elongated member and configured for attachment to a vehicle frame component. First bumper and second bumpers are co-axially disposed on the elongated member and spaced from a plate connected to an axle by a distance, wherein the distance is adjustable.
Claims12
A suspension system of a vehicle connecting a plurality of ground engaging wheels to a frame rail of the vehicle, the suspension system comprising:
- a forward axle and a rear axle, each axle connected to at least one of the plurality of ground engaging wheels, each of the forward and rear axles comprising a generally horizontal plate;
- at least one cushioning airbag mounted between the forward axle and the frame rail and at least one airbag mounted between the rear axle and the frame rail;
- a plurality of adjustable limiting assemblies configured to limit the relative vertical travel between the frame rail and the forward and rear axles, each of the plurality of adjustable limiting assemblies comprising:
- an elongated member having a longitudinal axis;
- an attachment mechanism disposed on an end of the elongated member and configured for attachment to the frame rail;
- a first bumper having a first spring rate and being co-axially disposed on the elongated member, the first bumper being positioned above the horizontal plate;
- and
- a second bumper having a second spring rate and being co-axially disposed on the elongated member and spaced from the first bumper, the second bumper being positioned below the horizontal plate;
- and
- a controller for adjusting the adjustable limiting assembly with respect to the horizontal plate in a range between a first position wherein the first bumper is proximate the plate and a second position wherein the second bumper is proximate the plate.
