A wheel suspension for mounting in a chassis of a working machine, said wheel suspension comprising a drive axle, a wheel and a hub device, said hub device comprising a first hub unit, which is stationary in the axial direction of the wheel suspension and connected to said axle, and a second hub unit, which is connected to the wheel, said second hub unit being adapted to be displaced in the axial direction of the wheel suspension relative to the first hub unit for altering the axial position of the wheel relative to the first hub unit, wherein the hub device also comprises an actuator for controlled actuation of the second hub unit to bring about said displacement. According to the invention, the actuator comprises a hydraulic cylinder (51), which is arranged inside a protecting and supporting means (52) for absorbing forces or force components in the radial direction of the hydraulic cylinder, said protecting and supporting means comprising a first supporting sleeve (53), which is adapted to be connected to the chassis, and a second supporting sleeve (54), which is directly or indirectly connected to the second hub unit, said supporting sleeves being telescopically arranged within each other for enabling a telescopic movement between the supporting sleeves.
