Vehicle wheel end assembly and a vehicle

A vehicle wheel end assembly comprising:

• a wheel hub having a central axis of rotation, which wheel hub is rotatably mounted on a wheel axle spindle by a wheel bearing comprising at least one roller bearing;
• wherein the wheel bearing has a bearing inner ring mounted on an external section of the wheel axle spindle and a bearing outer ring mounted in an internal section of the wheel hub;
• a threaded hub nut mounted at the end of the wheel axle spindle to fix the bearing inner ring in a predetermined axial position on the wheel axle spindle;
• and
• a rotational lock mechanism arranged to prevent relative rotation between the bearing inner ring and the wheel axle spindle;
• wherein the rotational lock mechanism comprises a tangential surface, wherein the tangential surface is a flat surface extending along the axial direction and along a tangential direction with respect to the axis of rotation,
• wherein the tangential direction is the chord of a circle segment portion corresponding to an inner circumference of the bearing inner ring,
• wherein the tangential surface is arranged in a plane located at or adjacent an outer radial end surface of the bearing inner ring;
• and the tangential surface is arranged in contact with a tangential recess in the peripheral surface of the wheel axle spindle to prevent relative rotation, and
• wherein an outer end of the bearing inner ring comprises a circumferential groove axially inside the tangential surface of the rotational lock mechanism for a sealing element between the bearing inner ring and the wheel axle spindle.
