A suspension assembly, including inner and outer tubes that are adapted to the telescope with respect to each other. A self-contained shock-damping cartridge is disposed in the tubes and is removable as a unit. The cartridge has first and second chambers, which contain hydraulic fluid. A shaft movably extends substantially completely through both chambers, and a piston is associated with the shaft and the chambers such that movement of the shaft within the chambers forces hydraulic fluid from one of the chambers to the other, thus damping telescoping movement between the tubes. The cartridge is sealed to substantially prevent the hydraulic fluid from entering and exiting therefrom during telescoping movement.

Suspension assembly for a vehicle

There is disclosed herein a suspension fork assembly particularly for use with bicycles. The assembly comprises an outer tube which is mounted via brackets to the steering tube of the bicycle frame, and an inner tube that telescopes within the outer tube. A shock absorbing system, preferably in the form of a cartridge is provided within the tubes. The inner surface of the outer tube and the outer surface of the inner tube each have a plurality of axially arranged opposing longitudinal flat sections, such as four on each tube. A plurality of needle bearings are disposed between the tubes on these flat sections. This arrangement, with the needle bearings arranged on the flat sections between the inner and outer tubes, allows the two tubes to freely telescope in and out with respect to one another without any significant static friction, and also serves to maintain torsional rigidity between the outer tube to the inner tube. The needle bearings thus bear radial loads as well as maintain the in line relationship of the outer and inner tubes for rotational forces while allowing the two tubes to freely telescope. Further, a rigid front blade is secured the inner tube to hold the front wheel of the vehicle and to provide bending and torsional stiffness.

Bicycle suspension system

There is disclosed herein a suspension fork assembly particularly for use with bicycles. The assembly comprises an outer steer tube which is adapted to be mounted in and extend through the head tube of the bicycle frame, and an inner steer tube telescopes within the outer steer tube. A shock absorbing system is provided within the tubes. The inner surface of the outer steer tube and the outer surface of the inner steer tube each have a plurality of axially arranged opposing longitudinal flat sections, such as four on each tube. A plurality of needle bearings are disposed between the tubes on these flat sections. This arrangement, with the needle bearings arranged on the flat sections between the inner and outer tubes, allows the two tubes to freely telescope in and out with respect to one another without any significant static friction, and also serves to transmit the torsional steering force from the outer tube to the inner tube. The needle bearings thus bear radial loads as well as maintain the in line relationship of the outer and inner tubes for rotational forces while allowing the two tubes to freely telescope.
