Assembly for supporting and drivingly connecting a wheel

An assembly (10) for supporting a wheel of a motor vehicle and for drivingly connecting the wheel to a driveshaft, comprising a wheel carrier (11) which is attachable to the motor vehicle and is provided with an annular part (15) and a plurality of steering arms (16);

• a wheel hub (41) which is rotatably supported in the annular part (15) of the wheel carrier (11) and is provided with a flange (46) for bolting on the wheel;
• a rolling contact bearing (51) with two rows (60, 61) of rolling contact members for supporting the wheel hub (41) in the wheel carrier (11), which rolling contact bearing (51) is insertable into the annular part (15) of the wheel carrier (11);
• and a constant velocity joint (71) which comprises an outer joint part (72) removably connectable to the wheel hub (41), and an inner joint part (77) connectable to the driveshaft, wherein the connection between the wheel hub (41) and the outer joint part (72) is provided by inter-engaging toothings (52, 75) of which a first toothing (52) is formed at a part of the wheel hub (41) and wherein a second toothing (75) is formed at a sleeve projection (82) at the outer joint part (72), and wherein the inter-engaging toothings are axially secured by a securing ring (57) which engages two annular grooves (53, 76) of which a first annular groove (53) is formed at said part of the wheel hub (41) in the region of the first toothing (52) and wherein a second annular groove (76) is provided at the sleeve projection (82) in the region of the second toothing (75),
• wherein, at the wheel carrier (112), in the annular part (152), in at least one circumferential position, there is provided a broken-out portion (272) which axially cuts into the annular part (152) from the joint end and wherein, with the rolling contact bearing (51) secured in the wheel carrier (112) and with the outer joint part connected to the wheel hub (41), the two annular grooves (53, 76) are positioned so as to axially correspond to the broken-out portion (272), and the securing ring (57) can be handled by pliers through the broken-out portion (272).
