DESCRIPTION

With the constant velocity joints the axleshafts form the set of devices which transmit motion from the gearbox to the driving wheels.

The assembly of these devices, commonly called "transmission" when in conjunction with the gearbox, comprises the following:

• right and left axle shafts;
• constant velocity joints on wheel and gearbox side.

The high-resistance steel axle shafts (11) have grooved ends to enable coupling with the constant velocity joints (12) and (13).

The housing for the flexible retainer rings (2) is made on these grooves.

The constant velocity joints are formed of an inner core (5) known as "drive", keyed onto the input shaft and an outer shell (6) called "driven", which forms the output element of the joint.

The inner core has six spherical grooves on its outer surface containing six balls (3), held in place by a cage (4).

These balls are the parts which actually transmit the motion and are also located in other grooves machined on the inner surface of the shell.
