The lower lever is firmly fixed by bolts on the crossbar of the suspension, which is attached to the front side meters. The stand of the mudguard is connected to the upper lever, but the lever has its own axis - its role is played by a long bolt passing through the rack.

To provide turns of the levers around the axis, the design provides silent blocks, which are rubber-metal hinges. Immediately at the ends of the levers there are ball hinges, which are connected to the swivel fist and the pin for mounting the hub. A sponge spring is located between the lower lever and the sprinkle stand. To fix it, the ends are mounted in the supporting cups.

Inside the spring is a hydraulic shock absorber, the housing of which is attached to the lower lever by means of a rubberometallic hinge. The shock absorber is attached to the body through rubber pillows. The cross-stability stabilizer is connected to the bottom levers of the chassis, and the center - with spars. To eliminate the contact of the stabilizer with spars, there are rubber pillows between them.
