A vehicle suspension system wherein the main attachment to the chassis of the steering and suspension components is by the king pin mounting. The suspension system includes a first member attached directly to a shaft rotating with the chassis attachment; a second member attached to the first member by a swivel joint or a bush, allowing vertical movement of a stub axle attached solidly to the second member; and a third member attached to the first member which acts as the steering arm connection ...

A non-torque reactive air suspension exhibiting excellent roll stability characteristics is shown to include frame hangers mounted to frame rails extending longitudinally on opposite sides of a vehicle. Longitudinally extending beams are connected to the frame hangers at one end and extend parallel to the frame rails. At their other ends, the beams are joined by a crossbrace extending laterally across the vehicle centerline. In a central portion thereof, the beams have an axle pivot bore to whic...

A wheel suspension with a wheel-guiding strut in provided which includes a helical compression spring, a shock absorber, and a suspension arm, and which is connected to a body and to a wheel. The helical compression spring is preferably made such that it at least partially compensates for transverse forces on the shock absorber or on the piston rod of the shock absorber. Provisions are made for reducing or minimizing or eliminating the force which is delivered to the steering mechanism and which...

A suspension system for an amphibious vehicle is able to be locked in either a lowered or in a retracted position according to whether the vehicle is on land or in water, respectively. The suspension system includes a main suspension arm pivoted to a vehicle hull at one end thereof and has a rotably mounted road wheel thereon at an opposite end thereof. A moving mechanism operably attached to the pivoted main suspension arm enables the arm and the road wheel to be retracted relative to the hull....

A suspension system for supporting a front wheel of a vehicle, such as a motorcycle, that includes at least one movement limiting device coupled to a support arm assembly and to a frame. The support arm assembly may support the front wheel and pivot about an axis that is generally orthogonal to a longitudinal axis of a vehicle and generally orthogonal to a longitudinal axis of the support arm assembly. The suspension system controls the amount of movement the support arm assembly undergoes about...

The invention provides a kit to enable a vehicle with an unequal arm type suspension to be replaced with a McPherson strut type suspension without modification to the vehicle chassis. A mounting assembly attaches to the upper suspension mounting points of the vehicle and the upper end of the McPherson strut attaches to the mounting assembly.

A vehicle suspension system comprising a frame and a pair of levers carried by the frame. Each lever is pivotally mounted for swinging movement on an axis extending transverse to the frame. A pair of forward-extending beams and rearward-extending beams have pivot connections with a respective lever and support a forward and rearward axle. Two forward springs and two rearward springs are each interposed between the beams and the frame. A pair of torque arms is carried by the frame forward of the ...

The present invention provides a vehicle suspension where bump stoppers are installed in an upper end of a strut and on an upper end of a lower arm respectively so that the bump stoppers can operate separately or simultaneously, depending on the size of a load, to absorb or reduce vibration or shocks. The vehicle suspension consists of an upper arm assembly being connected to an upper portion of a drive shaft assembly where wheels are connected; a lower arm assembly being connected to a lower br...

A suspension for coupling a steer axle assembly to a vehicle frame is provided that moves one or more of the spring reaction points outboard to increase roll stiffness and enable the use of a lighter axle. In one embodiment of the invention, the suspension includes a spring coupled to the vehicle frame and a shock absorber having a first end coupled to the spring and a second end coupled to a component of the steer axle assembly, such as the kingpin, at a location outboard of a longitudinal fram...

A watercraft has a pivoting, shock absorbing component that absorbs forces applied to its hull. The watercraft includes a hull, a deck coupled to the hull, an engine, and a jet propulsion system movably coupled to the engine. In one embodiment, a forward hull portion couples to the deck and a rearward hull portion movably couples to the deck and/or the forward hull portion. The jet propulsion system mounts to the rearward hull portion, while the engine mounts to the deck. A suspension element is...
