Milestone in the field of chassis technology

Fewer components, easier assembly

It is light. It assumes multiple functions. It also improves ride comfort: The 4-point link for MAN commercial vehicles in the aftermarket.

The result of permanent optimization

The weight-reduced 4-point link from LEMFÖRDER combines lightweight construction and functional optimization with an improvement of the dynamic driving properties.

  • Less weight

    The forged control arm was further developed and replaced by a cast control arm. This results in a 20% (12 kg) weight reduction. ZF is already working on the further development of the 4-point link. A prototype manufactured from glass-fiber reinforced plastics (GRP) is currently being tested.

  • More functions

    As the only solution of this type currently on the market, the 4-point link unites three chassis tasks in a single component: The longitudinal and transverse guidance of the axle as well as active roll stabilization.

  • Fewer parts

    V-links, stabilizers, and other chassis connection components can be omitted as a result of the functional expansion. This leads to a significant weight saving on the overall axle.

  • Less assembly work

    The reduced number of components means that assembly work is also reduced.
