Pic. 7.3. Rear Suspension Details: 1 - rubber-metal hinge; 2 – an arm of fastening of the suspension arm; 3 - shock absorber casing; 4 - compression stroke buffer; 5 - casing cover; 6 - support washer; 7 - shock absorber cushions; 8 - spacer sleeve; 9 - shock absorber; 10 - insulating gasket; 11 – rear suspension spring; 12 – lever connector; 13 – rear suspension beam arm; 14 - shock absorber mounting bracket; 15 - flange; 16 - lever bushing
The rear suspension beam consists of two trailing arms 13 (pic. 7.3) and connector 12, which are welded together through amplifiers.
In the rear part, brackets 14 with lugs for attaching shock absorbers and flanges 15 are welded to the suspension arms, to which the axles of the rear wheels are bolted along with the shields of the brake mechanisms of the wheels. In front, bushings 16 are welded to the suspension arms, into which rubber-metal hinges 1 are pressed. Bolts pass through the hinges connecting the suspension arms with stamp-welded brackets 2, which are attached to the body spars with welded bolts.
Suspension springs 11 rest at one end on the shock absorber cup 9, and at the other end through a rubber insulating gasket 10 into a support welded to the inner arch of the body.
Pic. 7.4. Shock Mount: 1 - protective cover; 2 – compression stroke buffer; 3 - support washer; 4 - insulating gasket of the spring; 5 - the upper support cup of the suspension spring; 6 - cushions for fastening the shock absorber rod; 7 - the lower support cup of the spring; 8 - shock absorber; 9 – a bolt of fastening of the shock-absorber; 10 – a bolt of fastening of an axis of a nave of a wheel; 11 – brake drum; 12 - hub bearing; 13 - wheel hub; 14 - axis; 15 - nut; 16 - retaining ring; 17 - locating pin
Shock absorber rear suspension hydraulic, telescopic, double-acting. It is attached with bolt 9 (pic. 7.4) to the trailing arm bracket. The rod is attached to the upper support 5 of the suspension spring through rubber pads 6 and support washer 3.
Pic. 7.5. Rear Suspension Shock Details: 1 - compression valve body; 2 - disks of the compression valve; 3 - throttle disk of the compression valve; 4 - compression valve plate; 5 - intake valve spring; 6 - clip of the compression valve; 7 - return valve nut; 8 - recoil valve spring; 9 – recoil valve plate; 10 - washer; 11 – recoil valve disc; 12 - throttle disc of the recoil valve; 13 - piston; 14 - piston ring; 15 - bypass valve plate; 16 - bypass valve spring; 17 - restrictive plate; 18 - remote bushing; 19 - tank; 20 - stock; 21 - compression buffer support; 22 - nut; 23 - stuffing box holder; 24 - protective ring of the rod; 25 - stuffing box; 26 - sealing ring of the reservoir; 27 - rod guide sleeve; 28 - cylinder; 29 - rubber-metal hinge
Details of the shock absorber are shown in fig. 7.5.
In hub 13 (see fig. 7.4) a double-row angular contact bearing 12 is installed, similar to the front wheel hub bearing, but smaller. In contrast to the front wheel hub, on which the inner ring of the bearing is installed with a guaranteed tightness, on the rear wheel hub, the bearing 12 on the axle 14 has a transitional fit.
