Suspension bracket and steering

THE GENERAL DATA

Specifications

ATTENTION

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



The general parametres
Base of wheels 2512
Track
Forward wheels 1513
Back wheels 1495
The minimum diameter of a turn, m 10.9
Steering
Design Реечное, with the hydraulic booster. A steering column – safety, telescopic, with inclination and length adjustment.
Liquid of the hydraulic booster of a wheel Oil for hydrosystems G 002 000
Forward suspension bracket
Design Independent with MacPherson's racks, screw springs, hydraulic shock-absorbers and the stabilizer of cross-section stability
Convergence of forward wheels 0 10 ' (0 1 mm)
Divergence at turn on 20
Models with a normal suspension bracket 1 30'
Models with a sports suspension bracket 1 31'
Disorder of forward wheels – negative (is regulated)
Models with a normal suspension bracket – 0 30 ' 30'
Models with a sports suspension bracket – 0 33 ' 30'
Longitudinal inclination of an axis of turn of forward wheels
Models with a normal suspension bracket 7 40 ' 30'
Models with a sports suspension bracket 7 50 ' 30'
Difference between the parties 0 30'
The maximum angle of rotation of an internal wheel
Models with a normal suspension bracket 38 30'
Models with a sports suspension bracket 38 15'

ATTENTION

Disorder of forward wheels can be changed by displacement of a beam of the power unit (work HUNDRED). Thus it is necessary to replace bolts of fastening of a beam of the power unit with the new.


Back suspension bracket
Design Semiindependent, consisting of a cross-section beam and two longitudinal levers. There is a stabilizer of cross-section stability. Springs and газонаполненные shock-absorbers are placed separately. All-wheel drive models are equipped by a suspension bracket with dual cross-section levers.
Disorder – negative (is not regulated) – 1 36 ' 20'
The maximum difference between the parties 30'
The convergence (is not regulated) + 025 ' 15 ' (2.77 1.66 mm)
Efforts of a tightening of carving connections
The moments of an inhaling of fixture are resulted also in the text of the Head and on some иллюстрациях*.

*Выделенные in the text a bold type the inhaling moments are subject to exact observance; the efforts not allocated with a bold type are resulted only roughly
