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 reliability.
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 steering wheel.
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 lengths.
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.
The boot kit consists of: boot, clamps, bolts, nuts, seeger, locking rings and grease.
The boots are made with two types of materials: rubber (used most often as it guarantees maximum ease in installation and reliability in time) and thermoplastic (more resistance to wear and corrosion by aggressive agents).
