Wheel force transducers (WFT) play an increasing role in endurance evaluation of road vehicles, ride and handling optimization, tire development and vehicle dynamics. Seven WFT-systems, which split basically into three design categories: strain gaged beam and spoke, individual load cells and mechanically separated load components are looked at in this investigation. After a general evaluation the two systems which seem to be most promissing are compared in more detail: Angle error correction and material selection (Titanium alloy versus carbon fibre composite) appeared to be the most significant differences of these two systems. FE-temperature analysis shows that during downhill braking temperature limits of the carbon fibre material are reached or exceeded. As in addition manufacturing of the special wheels (also partly made of carbon fibre) is expensive and cannot be done by the customer, using light weight metals seems to be the better choice.

Wheel force transducers (WFT) play an increasing role in endurance evaluation of road vehicles, ride and handling optimization, tire development and vehicle dynamics. With paper 980262 part I of an investigation of seven WFT–systems was presented. After a general evaluation two systems were compared in more detail. From a more basic interest deeper consideration was given to Angle Error Correction and material selection. This paper reports on part II of the investigation. The general evaluation of present systems on the market is updated and refined including new systems and updated versions. Thus an unique and quick overview is provided mirroring the present status of WFT technology. Special attention is given to systems best suited for applications in tire development, for driving dynamics optimization, active safety and active suspension development as well as in the ride and handling area.
