The rear axle of a Mercedes is a rear-wheel drive linkage system with independent wheel suspension. The elastic elements of the suspension are coil springs and gas-filled shock absorbers. The rear axle drive is located in the center. It is connected to the bearing beam of the bridge by three rubber mounts. The beam is attached to the load-bearing base of the body with four rubber supports. Thanks to the hydraulic damping of some of these rubber mounts, noise and rocking comfort is improved compared to conventional mounts. On both sides of the bridge beam, 5 guide and support arms are elastically fixed (Suspension arm, link, push rod, camber brace and toe link). Through rubber supports, the levers are fixed with their other side to the wheel hub. Springs and shock absorbers work between the suspension arm and the base of the body. The shock absorber is located near the hub and separate from the spring. As an additional equipment, the vehicle may have a ride height adjuster. Instead of gas-filled shock absorbers, in this case, hydraulic shock absorber struts are installed, into which, starting from a certain load, oil is automatically pumped up so that they take on part of the car's weight. This guarantees full spring travel and sufficient ground clearance for any load on the rear axle. Racks are installed in company workshops.
