FLEXIBLE STEERING IN TRAFFIC
BPW steering axles really come into their own in delivery and distribution transport. In contrast to rigid axles, they allow the trailer to corner better.

THE ECONOMIC MIRACLE AMONG THE BPW AXES
The self-steering axle LL really comes into its own on narrow traffic areas in delivery and distribution transport. Thanks to better manoeuvrability in bends and when manoeuvring and turning, you benefit from easier vehicle handling, protect the tyres and consume less fuel - up to 1,000 litres and over 4 tyres per vehicle with a mileage of 100,000 kilometres. Extrapolate that to your entire fleet!

THE FUNCTION OF THE SELF-STEERING AXLE LL
The abbreviation LL stands for ‘load-dependent steering stabilisation’ and describes the unique functional principle of the BPW self-steering axle. Conventional steering axle designs require power-assisted steering stabilisation elements - the BPW self-steering axle does not. The axle beam and steering knuckle are connected via steering pins with shaft-type thrust bearings. When travelling straight ahead (0 position), the wave-shaped thrust washers keep the wheels on track. The weight of the vehicle presses the shaft contours of the upper and lower thrust washers against each other. The wheels remain in the correct and stable straight-ahead position. If the semi-trailer follows the tractor unit into a bend, the caster ensures that the wheels turn in accordance with the bend radius (the pressure discs slide over each other).

GREATER MANOEUVRABILITY, LESS TRAFFIC SPACE REQUIRED
The frictional resistance changes depending on the load on the axle. This results in a load-dependent - and only mechanically controlled - steering angle (8° to 27°, depending on the vehicle version). The wheel-connecting tie rod locks both wheels when reversing by means of a steering lock.

ADDITIONAL MANEUVERABILITY
With the innovative auxiliary steering, BPW Active Reverse Control, the steering functionality and therefore also the manoeuvrability of the trailer is also available when driving forwards and backwards in manoeuvring mode. The vehicle can therefore manoeuvre in reverse more quickly and automatically. Collision damage can be avoided!
