Axle constructions - rear axle Rigid axle The rigid axle is characterised by very solid construction and high load-bearing capacity. With regard to driving behaviour and comfort, other axle designs such as the torsion beam and multilink suspension are far better. As the main advantage of this axle design is its load-bearing capacity, it is mainly used on goods vehicles. Another advantage is the low-cost production, and the totally constant castor and camber alignment over the entire driving distance. Torsion-beam rear axle The torsion beam axle is another form of rigid axle. Torsion beam axles include trailing arm axles which are often used on the rear in simple designs. In direct comparison with individual suspension, the trailing axle has the advantage that it is more economic to produce, takes up less space and still has excellent driving behaviour. Trailing arm axles are particularly suitable for use of torsion bar springs or profiles, as the control arms can easily be connected to the spring ends. More stable running is achieved with trailing arms as the control arms pull the wheels on forward motion. Multi-link suspension Multilink axles are a form of individual suspension and try to combine the benefits of trailing arm, semi-trailing arm and wishbone axles. On the Vectra-C, as well as the axle body this individual suspension has a upper and lower wishbones, where only the upper one is designed as an auxiliary control arm, and a trailing arm on each side. In addition on the Vectra-C there is an antiroll bar and an auxiliary control arm at the bottom. |
