Suspension bracket and steering

Specifications

Separate characteristics are provided also in the text of Head and in case of obligation of their performance are allocated with a bold print

Steering

Design

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

Power steering

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

Forward suspension bracket

Design

Independent, aluminum, on double levers with a beam connected with a body through rubber support, with Mac-Fersona racks, screw springs and gas-filled shock-absorbers. The forward beam via cross-section levers and drafts is connected with rotary support. The hydraulic opiraniye of cross-section levers provides compensation of fluctuations even at not balanced wheels. The stabilizer of cross-section stability is established
