Claim 0:
1. A wheel suspension arrangement comprising:
a suspension spring,
a plurality of control members arranged to control a stiffness of said suspension spring,
wherein the control members are displaceable relative to said suspension spring between a retracted position, in which the control members do not interfere with an operation of the suspension spring, and an advanced position, in which the control members interfere with the operation of the suspension spring in a way that a stiffness of said suspension spring is increased,

a biasing means configured to bias said control members towards said retracted position, and
a wheel connecting side and a vehicle body connecting side,
wherein control members located closer to the wheel connecting side are more strongly biased towards the retracted position than control members located closer to the vehicle connecting side,

wherein the plurality of control members are arranged to affect the suspension spring at spaced locations in a longitudinal axis of the suspension spring, and
wherein said biasing means comprises a plurality of control springs, wherein each one of said plurality of control members is coupled to a single respective control spring.
