RESILIENT AND LIGHTWEIGHT
BPW rigid axles are the strong backbone of your trailer.
They are tough, extremely resilient and pleasingly light.
Because in the course of ECO Plus 3, our designers were able to
reduced the tare weight per axle by up to 25 kg.
And for you, this means: a free ride for greater economy.
THE ONE-PIECE AXLE BEAM MAKES THE DIFFERENCE
The most important feature of a rigid axle is the connection between both ends of the axle by means of a single-part axle beam: If the position or angle of one wheel changes, e.g. during one-sided spring compression, the other wheels will be forced upwards. This also applies to changes in camber and toe-in. The axle transfers the static, dynamic and vertical wheel loads, longitudinal forces acting in the direction of travel (e.g. caused by braking) as well as transverse forces which occur during cornering, for example.
RIGID AXLES: THE FUNCTION IN BRIEF
The steering knuckle of the axle beam holds the wheel bearings and thus the hub, to which the wheel is mounted via the wheel bolts. Depending on the brake type, the brake disc or brake drum is connected to the hub. The brake carrier is welded to the axle beam and provides the connection to the brake. In the case of disc-braked axles, the brake calliper is bolted here; in the case of drum-braked axles, it holds the brake shoes. The axle integration connects the axle and suspension. Wheels, axle and suspension form the running gear and are mounted on the vehicle frame of the trailer or semi-trailer.
