The rear suspension has a 'torsion
axle' (semi-independent wheels).The advantages of this solution are:similar kinematic behaviour to independent
wheels with the relevant functional advantagesstabilizer function of the crossmemberlighterpre-ftting of the suspension before installing
it on the vehicle.The 'torsion axle' suspension is fixed to
the bodyshell by two brackets and the shock absorbers.The torsion beam rear suspension (dependent
wheels) includes the following components:Rear axle consisting of two steel tubular
longitudinal arms (diameter 75 mm and thickness 3.5 mm) with a circular
element welded at one end into which the flexible bushes are press-fitted
(conventional rubber-steel parts), a 'v' beam connecting the the
arms (in Fee420 pressed steel, thickness 4.0 mm) and two wheel side
mounting plates (one on each side) in FeP13 steel (4mm thickness,
type 188).The body retaining brackets are in pressed
steel (steel FeE355, thickness 3.5 mm); they are secured to the
body by 3 bolts.The shock absorbers are dual pipe type with
a horizontal lower bush (y axis) and an upper bush that is also
horizontal for fastening to the rear rail (the fastening system
is derived from the Punto).The coil springs rest between a lower plate
on the axle and an upper mount welded to the rail; a rubber element
is interposed between the upper mount and the spring.The end travel buffers are in rubber. For
this reason, due to their shape, they are secured to a mount welded
to the rear rail that also acts as an upper mounting surface for
the spring.The spindle is a Punto-derived forcged steel
component and is fastened to the wheel side mount plate by 4 bolts.The bearing is single-flanged and a Punto-derived
component.
