Independent suspension

Independent suspension

The wheel suspension assumes a crucial role in the vehicle chassis. It establishes the connection between the wheels and the vehicle’s body and transfers all forces and torques between the wheels and bodywork. The wheel suspension is intended to ensure safe driving characteristics and the highest possible comfort. There is a differentiation between independent suspensions, rigid axles and torsion-beam axles.
If the axle in question is a driving axle, it ensures that the driving force from the engine is transferred to the wheels. In addition, the front axle transfers steering motions to the wheels.

Hydraulic shock absorber

Hydraulic shock absorber

The hydraulic shock absorber mostly comprises of a cylinder filled with hydraulic oil and a piston, which moves with every vertical movement of the wheel. This piston glides up and down when the...

Wheel bearings

Wheel bearings

Wheel bearings guide and support shafts and axles. They are part of the chassis, guide the wheels and absorb axial and radial forces. Radial forces are longitudinal forces produced as a result of rotation...

Rigid axle

Rigid axle

The wheel suspension is the link between a vehicle’s body and its wheels. Alongside independent suspension and torsion-beam axles, rigid axles are among the most important construction types. Rigid axles are used in commercial vehicles and off-road vehicles due to their robust construction. In cars, they have been almost entirely superseded by independent suspensions (link: independent suspensions).

Torsion-beam rear axle

Torsion-beam rear axle

As load-bearing connections between the wheels and body, the axles assume a key function in the chassis system. The axles transfer all forces and torques between the wheels and vehicle bodywork. There is a differentiation between independent suspensions, rigid axles and torsion-beam axles. In the broadest sense, torsion-beam rear axles are a variant of the rigid axle.
