The back suspension bracket of the car dependent, includes directing device, elastic elements and the devices extinguishing fluctuations.
The directing device
The beam of the back bridge is connected with a body шарнирно, by means of jet bars – two bottom 3 and two top 17 longitudinal and one cross-section 22.
Longitudinal bars transfer pushing and brake efforts from driving wheels, through a beam of the back bridge to a body, the cross-section bar keeps a body from lateral displacement.
Jet bars fasten to arms of a body and a beam of the back bridge through резинометаллические hinges which are structurally executed equally and differ only in the sizes.
The hinge consists of the rubber plug 2 established in an eye of a bar, распорной plugs 1 which passes through an aperture of the rubber plug of a persistent washer and a bolt of fastening of a bar.
Elastic elements of a suspension bracket
Elastic elements of a suspension bracket consist of the twisted cylindrical springs 9, two basic buffers 6 courses of compression and the additional buffer of compression 16. Springs are sorted, under static loading 295 кгс, on two groups: And and.
Groups are marked similarly to groups of springs of a forward suspension bracket, i.e. Group And – a yellow strip, group – green. The spring established on a suspension bracket leans the top end against a basic cup 10 through a rubber isolating lining 11 which is placed in a steel stamped cup of 12 bodies. The bottom end of a spring leans in a cup of 5 beams of the back bridge through isolating plastic lining 4.
The basic buffers 6 are established in springs and fixed грибовидным by a nipple in apertures of the top support 10. The additional buffer 16 is established on an arm attached by bolts to the bottom of a body. In the end of a compression course the basic buffers rest in тарельчатое a collum of the bottom cup 5, and additional – against a special platform on картере a reducer of the back bridge.
The extinguishing device
The extinguishing device consists of two hydraulic shock-absorbers which device is described more low.
