摘要： A wheel bearing unit (9) rotatably supports a drivable wheel on a wheel carrier (10) around a rotational axis (15) and has a double-row tapered seat ball bearing with an outer bearing ring (20) attached to the wheel carrier (10) and a central bearing plane (24). The inner tracks (16, 17) are worked into the outer face (19) of an outer joint member (11) which carries a flange (12). The outer ball running grooves (30), formed into the outer joint member (11), are arranged opposite inner running grooves (35) of an inner joint member (34). The grooves, together with a cage (36) and guide balls (37), transmit torque. The inner joint member (34) is pivotable around the joint center (42) relative to the outer joint member (11). The central bearing plane (24) is offset from the joint center (42) by a distance sufficient to achieve the smallest possible rolling circle diameter. This leads to a lightweight unit which additionally ensures that during the transmission of torque, the joint does not adversely affect the bearing in the wheel carrier (10).
