Commercial vehicle rigid axle

The beam axle has a recapitulatory integral axle body (1) comprising a mutually integrated pneumatic spring leg (9), mutually integrated main bearings (8) and mutual integrated axles with bearing pins (7) and an X-shaped stiffening element (6). The axle body is made from continuous fiber-reinforced plastic e.g. flat fiber semi-finished material with fibers and a thermosetting or thermoplastic, which are arranged in a matrix. A resilient protective layer is formed on an entire surface of the axle body. Two longitudinal elements (11) and a transverse element are integrated with the axle body. The axle body is formed as a sandwich construction e.g. honeycomb structure and polymeric foam structure, where a sandwich core is made of balsa wood. The axle body comprises glass fibers, carbon fibers and aramid fibers. The beam axle is made of high-performance fiber composite material. The axle body is manufactured by a resin injection technique or a fiber winding technique.
