Chassis Milestone 4-Point-Link
Fewer Components, Easier Assembly

The four-point link for trucks - a joint development of LEMFÖRDER and MAN - is taking over the roll stabilization of large commercial vehicles in addition to the axle guidance system.

Four points to go ahead

The LEMFÖRDER four-point link was developed in cooperation with MAN Nutzfahrzeuge AG. It leads and stabilizes the rear axle of commercial vehicles. The four-point link from LEMFÖRDER is being developed as a weight-reduced variant made of fiber composite materials to meet the modern demands of lightweight construction.

The result of permanent optimization

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

  • Less weight

    The forged control arm has been further developed and replaced by a cast control arm. This results in a 20% (12 kg) weight reduction. ZF is already working on a 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 an 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.
