The axle plays a major role in the chassis system as a supporting link between wheels and vehicle body. All forces and moments between wheel and vehicle structure are transmitted via the axle. The drive axle ensures that engine motive power is transferred to the wheels. The front axle also transmits the steering movements to the wheels. Depending on vehicle design, ready-to-assemble Corner Modules are fitted. These include wheel suspension (knuckles and hubs, control arms, damper, spring) and braking system.
