4.2.1. Features of the device

Fig. 4.20. Details of a back suspension bracket: 1 – rubber-metal hinge; 2 – arm of fastening of the lever of a suspension bracket; 3 – shock-absorber casing; 4 – compression course buffer; 5 – casing cover; 6 – basic washer; 7 – shock-absorber pillow; 8 – expansion plug; 9 – shock-absorber; 10 – the isolating laying; 11 – spring of a back suspension bracket; 12 – connector of levers; 13 – lever of a beam of a back suspension bracket; 14 – arm of fastening of the shock-absorber; 15 – flange; 16 – lever plug

The beam of a back suspension bracket consists of two longitudinal levers 13 (fig. 4.20) and a connector 12 which are welded among themselves through amplifiers.

In a back part arms 14 with eyes for fastening of shock-absorbers, and also flanges 15 to which fasten bolts of an axis of back wheels together with boards of brake mechanisms of wheels are welded on levers of a suspension bracket. In front levers of a suspension bracket have welded plugs 16 in which rubber-metal hinges 1 are pressed. Through hinges there pass the bolts connecting suspension bracket levers to stamped and welded arms of 3 (fig. 4.21) which fasten to body longerons welded bolts.

Fastening of the shock-absorber: 1 – protection cover; 2 – compression course buffer; 3 – basic washer; 4 – the isolating laying of a spring; 5 – top basic cup of a spring of a suspension bracket; 6 – pillows of fastening of a rod of the shock-absorber; 7 – lower basic cup of a spring; 8 – shock-absorber; 9 – bolt of fastening of the shock-absorber; 10 – bolt of fastening of an axis of a nave of a wheel; 11 – brake drum; 12 – hug bearing; 13 – wheel nave; 14 – axis; 15 – nut; 16 – lock ring; 17 – adjusting pin; In – a point for orientation of the shock-absorber

Shock-absorber of a back suspension bracket hydraulic, telescopic, bilateral action. It fastens a bolt of 9 (fig. 4.22) to an arm of the longitudinal lever of a suspension bracket. Top fastening of the shock-absorber shtyryevy: the rod fastens to the top support 5 of a spring of a suspension bracket through rubber pillows and a basic washer 3.

Details of the shock-absorber of a back suspension bracket: 1 – return valve nut; 2 – return valve spring; 3 – plate of the return valve; 4 – washer; 5 – return valve disks; 6 – throttle disk of the valve of return; 7 – piston; 8 – piston ring; 9 – plate of the perepuskny valve; 10 – spring of the perepuskny valve; 11 – restrictive plate; 12 – remote plug; 13 – tank; 14 – rod; 15 – compression buffer support; 16 – nut; 17 – epiploon holder; 18 – protective ring of a rod; 19 – epiploon; 20 – sealing ring of the tank; 21 – the directing rod plug; 22 – cylinder; 23 – compression valve holder; 24 – spring of the inlet valve; 25 – plate of the compression valve; 26 – throttle disk of the valve of compression; 27 – compression valve disks; 28 – compression valve case; 29 – rubber-metal hinge

Details of the shock-absorber are shown in fig. 4.23.
In a nave 13 (see fig. 4.22) the two-row radial-stop bearing 12, similar is installed to the hug bearing of a forward wheel, but smaller dimension. Unlike a nave of a forward wheel where the internal ring of the bearing is established on a nave with the guaranteed tightness, the bearing 12 on axis 14 has transitional landing.
