Abstract: The invention relates to vehicle suspension systems of the type with a trailing arm, and to a seat for securing the trailing arm to an axle or axle casing. Hitherto, trailing arms have been located on axles or axle casings and held in place by the force of U-bolts holding the trailing arm to the axle. Under excessive loads as can be applied to vehicle suspension systems, trailing arms can be moved out of alignment to the detriment of the running of the vehicle. To avoid such movement, seats for trailing arms are known to be welded to vehicle axes or casings and to which the trailing arms are secured such as by U-bolts.

Abstract: A material handling lift for moving a load horizontally over a surface and vertically with respect to that surface and a suspension system for the material handling lift. The material handling lift includes a frame with wheels for traveling over the surface. At least one of the wheels is a drive wheel mounted on a vertically-oriented steering column. The steering column is connected to the frame by a parallelogram type suspension system which includes swing arms that are pivotally connected to the frame. A stabilizer bar is connected between the free ends of the swing arms and a shock dampener is connected between the frame and a swing arm. The suspension system helps dampen the shock of traveling over uneven terrain, helps to keep the steering column vertical and the wheels of the vehicle on the ground thereby helping to maintain constant traction with the surface and control of the steering, braking and acceleration of the vehicle.

The suspension system incorporates an axle saddle configured for more strongly welding to the axle, as well as a composite construction for the rocker to make a tube and thereby achieve a more strongly welded connection to the axle saddle. The suspension system further incorporates a rocker-to-hanger rocking axis alignment subsystem as well as a shock-absorber protection subsystem.

Abstract: A compressible link suspension system for a wheel of a multi-wheel vehicle that has a frame and an axle for the wheel.

Abstract: A pivot bearing used in a vehicle trailing arm suspension includes a housing, a resilient bush compressed and bonded in the housing, and a rigid axial sleeve in the bush. The bush has voids, above and below the sleeve when the pivot bearing is fitted for use and stiffening elements which extend between the voids at opposite sides of the sleeve. When the pivot bearing is in use in a vehicle trailing arm suspension, the voids increase flexibility of the bush under generally vertical loading on the pivot bearing. The stiffening elements enhance the stiffness of the bush in generally horizontal direction for improved vehicle dynamics and reduced vibration. Preferably, the stiffening elements are of plate or leaf form, are bonded to the bush, and extend arcuately about the sleeve. The voids extend partially through the axial thickness of the bush from opposite ends of the bush and generally accurately about the sleeve. The bush also has enlarged opposite circumferential end portions.

Abstract: A knuckle is minimized in size to be located in an internal space of a rear wheel. An upper arm is disposed lower than a conventional double wishbone type and one end of the upper arm is secured to the knuckle.

This configuration thus constructed greatly increases the space of the trunk room, reduces noise by minimizing the transmission of road impact and vibration, and improves ride comfort as well as braking stability and turn stability.

Abstract: A progressive rear suspension linkage is used in the rear suspension of an ATV to aid in ride quality and safety by changing leverage ratio thru the travel of the rear suspension. The rear shock attaches to it as well as to the frame. The linkage system attaches to the frame at one end and to the rear suspension arm at the other end and changes leverage as the mounting point on the frame and the rear suspension arm come closer together or further apart as the rear suspension arms moves thru its travel. This in turn lets some linkages move in a scissors type movement with the rear shock bolted to it at a given point. This invention provides an improvement to the OEM designs, making for improved handling and safer control of ATVs.
