Suspension bracket and steering

Specifications

Separate characteristics are resulted also in the text of the Head and in case of compulsion of their performance are allocated by a bold type

Steering

Design

Zubchato-reechnogo type with the hydraulic booster which factor of strengthening depends on number of turns of the engine. On some models hydraulic booster Servotronic which factor of strengthening depends on speed of movement is established. The pillow of safety of the driver is located in a steering wheel

The wheel hydraulic booster

Oil ATF, for example,
Shell ATF Dexron II D-21-631
Mobil ATF 220 D-20104
Total Dexron II D-21298

Forward suspension bracket

Design

Independent, aluminium, on double levers with a beam connected with a body through rubber support, with racks the Poppy-fersona, screw springs and газонаполненными shock-absorbers. The forward beam through cross-section levers and draughts is connected with rotary support. Hydraulic опирание cross-section levers provides indemnification of fluctuations even at not balanced wheels. The stabilizer of cross-section stability is established
