Monobloc joint with centering means

An assembly comprising a constant velocity universal joint connected to a gearbox output shaft (12), the constant velocity universal joint comprising an outer joint part (50, 60), an inner joint part (25) and torque transmitting elements (33, 34) which, in the direction of rotation, constitute positive engaging means between the outer joint part (50, 60) and the inner joint part (25), and having a shaft attachment flange (17) circumferentially secured to the outer joint part on a diameter outside a rolling circle of the torque transmitting elements (33, 34) and with there being provided centering means for centering the outer joint part (50, 60) relative to the shaft attachment flange (17), wherein the outer joint part (50, 60) comprises an integrally formed-on base (51, 61) towards the shaft attachment flange (17), and wherein the centering means are provided directly on the base (51, 61) on a diameter inside the rolling circle of the torque transmitting elements (33, 34), wherein the shaft attachment flange (17) includes a splined sleeve (l8) adapted to be slid onto a splined portion (15) of the gearbox output shaft (12) such that the gearbox output shaft (12) passes through the shaft attachment flange (17) and registers with said centering means by way of matching centering means, and wherein the centering means have a diameter inside the splines diameter of the splined sleeve (18).
