Abstract: A wheel axle suspension having on both sides of a vehicle a trailing arm which extends in the longitudinal direction of the vehicle, a thin walled tubular axle body, which has attachment regions where the axle body is attached to the trailing arms. Each trailing arm is hingedly connected at the front, viewed in the direction of travel of the vehicle, to a bearing bracket which is arranged on the vehicle chassis. The suspension also comprises a pneumatic spring operational between each of the trailing arms and the chassis, and clamp bodies for clamping the axle body at the attachment regions thereof so as to attach the axle body to the trailing arms, as well as tensioning elements for providing the clamp force for the clamp bodies.

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.

Abstract: The invention relates to a method for manufacturing of a flexible trailing arm for a wheel axle suspension of a vehicle such as a lorry or a trailer. In the method a steel blank is heated. Next, the blank is formed into the desired shape of the trailing arm by means of a suitable forming process. Following that the trailing arm is austempered by cooling it in a warm fluid medium.
