Rear wheel suspension with coil springs with an inclined reaction force axis

The axle (5) has longitudinal rocker arms (2) connected by a welded profile (3) and attached to a compression spring (7). The spring has a spring middle line and a force action line, and guided by a guiding element in upper and lower spring bearings. The guiding element is attached to an outer circumference of the spring, where the force action line has inclination value during deflection. An upper penetration point of the force action line is arranged proximate to the spring middle line than a lower penetration point of the force action line when the spring deflects or rebounds.
