Editing Unimog (section)

=== Suspension ===
The Unimog has live front and rear axles that have portal gears ([[portal axle]]s). Such axles have a lifted axle centre, but the wheels' centre remains unchanged, meaning that a high ground clearance can be achieved with small wheels and tyres. Unlike "regular" trucks, the Unimog has [[coil spring]]s with hydraulic [[shock absorber]]s rather than [[leaf spring]]s, as coil springs provide more spring travel. The axles themselves have only one longitudinal pivot point each, the so-called [[torque tube]]s. The torque tubes contain the drive shafts and connect the axles' differential gearboxes to the Unimog gearbox, but being also parts of the suspension system, the torque tubes prevent longitudinal movement of the axles, whilst still allowing limited vertical movement. Lateral axle movement is prevented by [[panhard rod]]s and [[transverse link]]s. This design results in extreme axle angle offsets of up to {{val|30|u=°}} possible.<ref name=Vogler_2016 />{{rp|36–40}}

A wide variety of wheels and tyres were available for the Unimog. Originally, the first Unimog was equipped with 6.5–18&nbsp;in tyres designed for both on- and offroad use.<ref name=Vogler_2014 />{{rp|48-49}} Later, bigger wheels and tyres with different tread patterns were available, reaching from agricultural tractor tread patterns to massive bar tyre treads to low pressure ballon tyre treads. Until 1973, drum brakes were standard for all Unimogs, until they were replaced by disc brakes, however, until 1989, drum brakes remained an option for Unimogs of the 406-family.<ref name=Vogler_2016 />{{rp|78}} The steering system used to be a screw-and-nut system until 1970. Then it was replaced by a power assisted ball-and-nut system for the 406-series.<ref name=Vogler_2016 />{{rp|77}}
