GSLL 14000

BPW GSLL steering axle. The abbreviation “LL” stands for “Load-dependent steering axle stabilisation” and describes the unique operating principle of the BPW self-steering axle. Conventional steering axle designs require external power-assisted steering stabilisation elements - this is not the case with the BPW self-steering axle.

With the BPW combination cylinder, the axle can be used as self-steering axle or also as force-steered axle. The multi-functional use of the steering axle reduces the warehousing at the vehicle manufacturer. This allows the decision between force and self-steering to be made at short notice.

The axle beam and axle stub are connected via steering pivot with undulated thrust bearings. When driving straight ahead (zero position), the wave-like thrust washers keep the wheels on track. The weight of the vehicle presses the wave contours of the upper and lower thrust washers together. The wheels remain stable and aligned in the forward straight ahead position. When the trailer follows the tractor into a curve, the wheel castor ensures the wheels turn in accordance with the curve radius (the thrust washers slide over one another). The steering axle has the effect that the unit steers better into the curves and almost follows the circular path of the tractor. The lateral tyre forces occurring in the process are distributed optimally to all axles.

Steering angle sensor is a key element of electronic force steering, integrated at the pivot point of BPW Agrar steering axles. It enables precise detection of the steering angle and allows seamless use of advanced sensors from leading manufacturers
