Line composed by: constant velocity joints wheel and gearbox side
for most European and Asian vehicles: a technologically advanced production
system for manufacturing the three main parts (bell, cage and race)
involving high-precision mechanical engineering and absolute product
The three steel component parts, treated so as to offer the utmost
resistance to wear, are ground in compliance within tolerances of
just a few hundredths of a centimetre and therefore ensure, thanks
to the use of high-precision balls, extremely regular movement.
A vast range of driveshaft for European vehicles, made to the highest
quality standards, complete the transmission line.
Constant Velocity Joints
Constant velocity joint is a kind of joint which allows to keep at
same velocity the axel's rotation on condition that the angle between
constant velocity joints will not exceed a certain limit.
In case of FWD cars the need to transmit the torque to steering wheels
determined for years big difficulties in realization.
Infect the joint between driveshaft and wheel shaft creates a connection
of 2 components which when steering create a relevant angle.
If the joint would not be of constant velocity (that means it would
create differences on velocity between driveshaft and wheel) it would
cause stress that would injure transmission besides vibrations on
These are the shafts positioned cross ways from the direction of travel,
which link the wheels to the differential gear and are therefore part
of the transmission.
In the event of independent suspensions, they are fitted with joints
at their ends to allow for wheel oscillation.
The axle shafts transmit motion to the wheels, allowing them, where
required, to turn at different speeds in order to cover paths of differing
The purpose of this is clear when one thinks what would happen if the
driving wheels were rigidly connected, that is, obliged to turn at the
same speed; since the internal one on a bend covers a shorter path than
the external one, one of them (or both) would skid, causing serious
damage to the life expectancy of the tyres and reducing road grip
