Suspension bracket and steering
Specifications
| |
Separate characteristics are provided also in the text of the Head and in case of obligation of their performance are highlighted in bold type |
Steering
|
Design |
Gear and rack type with the hydraulic booster whose coefficient of strengthening depends on engine speed. On some models the Servotronic hydraulic booster whose coefficient of strengthening depends on the speed of the movement is installed. 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 the beam connected with a body through rubber support with Mac-Ferson's racks, screw springs and gas-filled shock-absorbers. The forward beam via cross levers and drafts is connected with rotary support. The hydraulic opiraniye of cross levers provides compensation of fluctuations even at not balanced wheels. The stabilizer of cross stability is installed |

Back suspension bracket
| Design |
Multilever, aluminum, with a stretcher and a double elastic suspension bracket of the main transfer. Four cross levers are elastically connected with a stretcher. The stretcher is also elastically connected with a body. |
