Abstract
A wheel carrier is a commercial vehicle-specific component which connects the wheel to the wheel bearing and transfers the loads between the two parts. This paper presents a novel design, manufactured from an aluminium alloy. Finite Element (FE) modelling was extensively used to ensure structural strength, and brake cooling tests were used to assess improvements in heat dissipation. The newly developed prototype carrier has only half the mass of the original Spheroidal Graphite (SG) design, saving 11 kg per ‘wheel end’. Brake cooling is also considerably improved, with the average convective heat transfer coefficient being increased by 50%.
