Abstract: A wheel suspension system for reducing or eliminating the shock associated with travelling over bumps and dents on a roadway on a wide variety of low speed wheeled transportation equipment. The system includes substantially vertically positioned swing arms connected between the wheel axle and frame of the wheeled transportation equipment.

Furthermore, the system keeps the gravity center of the frame of the wheeled transportation equipment at a similar level to that with no suspension system and also increases the wheel's ability to overcome large obstacles.

Abstract: An adjustable fluid damping system for use in a suspension system that undergoes compression and rebound. The fluid damping system permits independent adjustment of compression and rebound damping by providing separate compression and rebound damping circuits. Each circuit has a flow path with an inlet through which damping fluid flows during damping, and an adjuster that adjusts the degree to which the inlet is open and hence damping through that flow path. The compression and adjusters are selectively and independently coupled to the same adjuster rod via respective compression and rebound couplers. The adjuster rod can be coupled to only one of the couplers at a time. Rotation of the adjuster rod by means of an adjuster knob, which can be pulled outward or pushed inward to engage one of the compression and rebound couplers, causes rotation of the coupler coupled thereto and axial movement of the respective adjuster to modify damping through the associated damping circuit.

Abstract: A pedal cycle is disclosed, which has a rear wheel suspension pivoted to the main frame and a front wheel suspension pivotally and slidably mounted to the main frame. Front and rear suspensions are provided and are interconnected, for example, by a rod to transmit forces between them. Any load on one wheel, tending to lift that wheel by movement of its suspension relative to the main frame, is transmitted to the other suspension thereby tending to lift that suspension relative to the main frame. Further, load placed on the front suspension by a rider pushing downward on a forward pedal causes a force to be transmitted to the rear suspension in opposition to a force applied to the rear suspension by a tension developed in the transmission chain owing to the force applied by the rider to the forward pedal. The interaction between transmission and suspension provides for a cycle with better responsiveness than in a conventional cycle.
