The rear suspension is made on two longitudinal leaf springs with two hydraulic shock absorbers
Suspension can use small or multi-leaf springs.
The leaf spring consists of three sheets.
Multiple leaf springs are bundled in packs of five, flat side up.
The top three sheets are tied together with clamps, and the entire package is connected with a center bolt.
The spring is attached to the brackets of the frame spars through two upper sheets, the ends of which are bent and form ears.
The rear eye, formed only by the top sheet, is attached to the bracket through an earring that compensates for the change in the distance between the ends of the spring during suspension operation.
All movable connections: front and rear spring mounts, clevis mount, upper and lower shock absorber mounts are assembled on rubber bushings.
The springs are attached to the rear axle with stepladders through linings, gaskets and pillows.
On trucks and vans, an additional spring is located on top of the main spring, consisting of one or three sheets.
Its ends do not have lugs and, when the vehicle is loaded, rest on rubber cushions installed in the frame brackets.
Buses have a rubber buffer instead of an additional spring.
Shock absorbers - telescopic, two-pipe, collapsible.
The lower end (reservoir) is attached to the spring pad, and the upper end (rod) to the frame spars.
Replacement of springs can be found in the article - Replacement and repair of the rear springs.
We look at the replacement of shock absorbers in the article - Replacement of suspension shock absorbers.
On request, a rear suspension stabilizer can be installed on the car, consisting of a rod, brackets, earrings, rubber bushings and mounting bolts.
Due to its installation, the lateral stability of the car is increased.
Possible malfunctions of the rear suspension
Frequent "breakdowns" of the suspension:
- - Vehicle overloaded
Do not overload the vehicle
- - Breakage of leaf springs
Replace spring or broken leaves
- - Residual deformation of the sheets of springs or one of them ("springs "sagged")
Replace spring or springs
"Breakthroughs" are accompanied by a metallic knock:
- - Lost or corrupted bounding buffer or buffers
Set new buffer or buffers
The car "leads" to the side:
- - Displacement of the rear axle relative to the spring due to loosening of the stepladder nuts
Loosen the ladders, put the bridge in place and tighten the ladders
- - Displacement of the root sheet when the center bolt is destroyed
Replace center bolt
- - Root leaf breakage
Replace Root Leaf
Car roll to one side:
- - Breakage of leaf springs
Replace springs or individual leaves
