Abstract

A shock absorption system for an electric unicycle comprising a system of movable rigid members ( 1 ), ( 2 ), ( 3 ), pivotally connected to each other and to a shock absorber ( 4 ) forming a closed kinematic chain which has two interconnected loops—one in a shape similar to a trapezoid, and other resembling a triangle pivotally attached to a rigid frame at three points, where the top and bottom levers are oriented parallel to each other in all positions of the kinematic chain, and the shock absorber ( 4 ) is oriented predominantly vertically at an angle different from zero degrees relative to a direction of cushion forces.

Claims (3)

1. A shock absorption system for an electric unicycle comprising a system of three movable rigid levers pivotally connected to each other and to a shock absorber forming a flat closed kinematic chain characterised by the fact that the kinematic chain has two interconnected loops—one resembling a trapezoid and other resembling a triangle pivotally attached to a rigid frame of the unicycle at three points, wherein

the top and bottom levers remain parallel to each other in all positions of the kinematic chain and the shock absorber, as an integral part of the closed kinematic chain, is oriented predominantly vertically at a nonzero angle relative to a direction of cushioned forces.

2. The shock absorption system according to claim 1 , wherein the two closed kinematic chains are mounted in parallel on both sides of a unicycle wheel.
