Abstract: A vehicle lowering system is provided having a movable arm that is connected to a vehicle through an upper link and a lower link. The upper and lower links pivot with respect to the vehicle on pivot points on one end and pivot with respect to the arm on pivot points at the opposite end. The spacing of the pivot points and the length of the upper and lower arm create an instant center, about which the movable arm pivots. An actuator is connected to the vehicle on one end and the movable part of the suspension on the opposite end. The actuator is movable between an extended and a retracted position. When the actuator moves between the extended and retracted position, the movable arm moves the vehicle between a raised and a lowered position.

Abstract: A suspension for a trailer vehicle that allows the trailer itself to be used as a ramp. The suspension has an axle having an axis and wheels at each end of the axle. The axle is pivotally connected to the vehicle at a pivotal connection and the axis of the axle is offset from the pivotal connection to the vehicle. An actuation device having a first and second end is pivotally connected to the axle at its first end. The actuation device is movable between a retracted length and extended length. Shifting the actuation device between its retracted and extended lengths causes the axle to pivot about the pivotal connection on the trailer, thereby changing the height of the vehicle relative to the ground surface. The trailer can be used as a ramp, thus, eliminating the need for separate ramps.

Abstract: Improvements in a lowerable trailer that uses pneumatic cushions to provide both the cushioning of the trailer bed and raising and lower of the trailer bed.
