Abstract
A wheel axle suspension adapted to suspend an axle body of a wheel axle from a vehicle chassis comprises on both sides of the vehicle a bearing bracket arranged on the vehicle chassis. A rigid or flexible trailing arm extends in a longitudinal direction of the vehicle. The trailing arm has a resilient bush at a front end by means of which the trailing arm is hingedly connected to the bearing bracket. The trailing arm furthermore has a contact region essentially complementary to a portion of the outer contour of the axle body, where the axle body, in a fitted position, bears directly against the trailing arm. A support part opposes the contact region of the axle body. The support part is provided with a recess for accommodating the axle body, and is provided with a securing arm extending further towards the rear which is adapted to be secured to a pneumatic spring. Tensioning elements are provided tensioning the support part and the contact region of the trailing arm towards each other against the axle body. A pneumatic spring is provided which is operational between the securing arm and the vehicle chassis.
