The driveshafts (1), made from high resistance
steel, have splined ends to allow matching with the constant velocity
joints (2).The constant velocity joints are composed
of an innerl "drive" core (3) fitted on the input shaft
and an outer "driven" shell (4), which is part of the
coupling output.The inner core has six spherical splines
on the outer surface which contain six balls (5), kept in place
by a chamber (6).The balls are the true drive transmission
element, because they are simultaneously housed in the same number of
grooves on the inner surface of the shell.The intermediate shaft (1), made from high
resistance steel, connects the flange and the differential with
the right driveshaft by means of the splined end.To limit the projection between the mounting
points, the intermediate shaft is supported by a seat on the gear casing.
