HSWL 256 The challenging requirement of the PUMA design is that the vehicle is air transportable in the A400 M for peace keeping missions, which imposes a strong limit to the vehicle weight. Equally the PUMA must be fully upgradeable for high intensity combat, with its requirement of significantly higher vehicle weight than the level of protection demands. The solution is the HSWL 256 transmission combining a most compact design with regard to size and volume while also using lightweight components with long term durability and high performance, capable to drive, brake and steer the vehicle over a very wide range of vehicle weights.

Reliability on the test rig

Born by the necessity to develop and build test rigs for own products the independent Test System Division was created at RENK in 1986. The experience grown over decades in the field of power transmission technology, measuring technology, electronics, hydraulic systems and system construction could be entered in concentrated form. Today RENK offers his customers of the vehicle, railway and aerospace industries complex test systems exactly tuned to the respective product for turnkey delivery by the affiliated company RENK TEST SYSTEM GmbH in Augsburg. These test systems are applied for research and development, manufacture and quality assurance. The spectrum ranges from component test rigs and extended components for already existing plants up to complete vehicle test rigs. The computer controlled systems allow to physically test drive systems, transmissions, brakes and similar components of heavy vehicles under realistic conditions. Thus safety and resistance of mobile components e.g. in the passenger car and helicopter construction can be proven and possibly enhanced. Moreover, the modern test systems even allow the diagnosis itself of functional efficiency and safety of the manufacturing plants.
