4 Claims.
'1
.Inthe present day vehicle suspensions, the ‘two
vfront or rear wheels rotate on the journals of the
‘same axle which is connected to the chassis ‘by
vmeans of springs.
,_
Consequently, if oneof the wheels is lifted, the
axle bears on the other wheel and. forms a lever
and lifts the vehicle.
,
.Oln theother hand, in the case of an automobile
.or truck, as the back axle is very heavy, its in
ertia produces violent reactions, on the one "hand
on the vehicle which is thus subjected ‘toshocks,
and on the other hand on the tyres which under
go rapid wear.
