double accting and pressurized to reduce operating noise. The walls
and spring plate are made of reduced thickness high-tensile steel.
The top mounting comprises a flexible isolation of the stem, separated
from the spring mounting (by interposing a rubber pad) and the buffer.
A tapered retaining system eliminates the need to bolt the block
to the body. This brings advantages in terms of assembly and reliability.
At the top of the shock absorber, there is a top end-of-travel buffer
made of 'CELLASTO' (closed-cell polyurethane, a material which retains
its original elasticity characteristics for a long time) which intervenes
gradually as the shock absorber homes on bends.The bottom of the shock absorber is attached
to the hub, which in turn is attached to the suspension's longitudinal
track control arm. On the stem there is also a bracket for anchoring
the torsion bar reaction link Characteristic of working principle 4420C rear suspension stabilizer
bar/links .
Springs
The coil springs are mounted in a very offset
position in relation to the shock absorber axis, to reduce sliding
friction. On the coils resting on the top and bottom plates, there
is a rubber ring to prevent operating noise.
