Description

The disk brake axles have a 120 mm offset and 19.5 or 22.5 inch wheel sizes. The disk brakes are from WABCO, a leader in heavy commercial vehicle brake solutions offering the optimum combination of weight and performance. Ventilated disks to VALX design ensure excellent brake cooling.

WABCO’s PAN 19-1 and PAN 22-1 calliper types are standard fitment. WABCO’s proven reliable single-piston technology has made the PAN range one of the most successfull air disk brake ranges. The compact design is based on the careful combination of FEM (Finite Element Method) calculations and the patented single-piston technology. The result is significant vehicle weight improvement in all classes. The universal WABCO/VALX callipers are field‑replaceable by other standard components for optimum serviceability.

Axle beam

The axle is based on an extremely strong seamless, cold-drawn beam design. The non-welded beam structure eliminates risks of weakening or material degradation. The VALX axle beam has a higher strength-to-weight ratio than any other in Europe, and forms the basis for long-term durability under tough operating conditions.

Air suspension

The specially developed Weweler air suspension meets the VALX philosophy of light weight, low component count and minimal maintenance. A wide range of ride heights and offsets can be accommodated by only one type of shock absorber, air spring, hanger bracket and two different tail ends.

Hub

Highly accurate CNC machining and reduced tolerances ensure accurate bearing pre‑setting and an even pressure distribution across the bearing cups. The wide bearing spread minimises bearing loads and maximises bearing life, while reducing sensitivity to brake heat transfer.

Bearings

The bearing solution is based on two single-row preset tapered roller bearings, combining cost-effective maintenance with maximum performance and reliability with minimum total cost of operation. Optimised pre-setting maximises bearing life and brake performance.

Seal

For the VALX axle hub SKF supplies the specially developed Scotseal PlusXL, made of high-temperature resistant, long-life HNBR rubber to exclude dirt and moisture from the wheel bearings. Together with the bearings themselves, the seals are retained in place by a circlip when the hub is removed, simplifying service and maintaining the integrity and cleanliness of the hub assembly.
