The hub lock nut assembly comprising a hub lock nut and a mating component with which the hub lock nut is arranged to be mated in a mated position. The hub lock nut comprises a circumferential inner wall defining a central hole, the inner wall having a threaded portion. One of the hub lock nut or the mating component comprises at least one resilient portion adapted to be movable in a radial direction outwardly of the central hole when subjected to an external force provided by the other of the mating component or the hub lock nut. The at least one resilient portion having an engagement area for receiving said external force, wherein the engagement area is located radially outwardly of the threaded portion. ## Claims ### Claim 1 A vehicle wheel hub lock assembly for retaining a vehicle wheel hub in position, the vehicle wheel hub lock assembly comprising: a vehicle wheel hub lock nut comprising: a circumferential inner wall defining a central hole, the inner wall having a threaded portion; and at least one resilient portion; and a mating component with which the vehicle wheel hub lock nut is configured to be releasably mated in a mated position, the mating component constituting part of a vehicle spindle, vehicle knuckle, or vehicle wheel axle portion; wherein the at least one resilient portion is adapted to be movable in a radial direction outwardly from the central hole when subjected to an external force provided by the mating component, the at least one resilient portion arranged to provide prevailing torque to the vehicle wheel hub lock nut when subjected to the external force, the at least one resilient portion having an engagement area for receiving the external force, wherein the engagement area is located radially outwardly of the threaded portion in the mated position; and wherein the mating component comprises a protrusion extending radially outwards from the mating component and configured to subject the resilient portion to the external force in the mated position. ### Claim 2 (depends on 1) The vehicle wheel hub lock assembly of claim 1, wherein the at least one resilient portion is in the form of a snap collar portion located radially of the threaded portion and projecting axially away from the threaded portion, the at least one resilient portion being adapted to flex in the radial direction outwardly from the central hole when subjected to the force. ### Claim 3 (depends on 1) The vehicle wheel hub lock assembly of claim 1, wherein the central hole is further defined by a circumferential non-threaded portion, wherein a ledge extends radially outwardly from the threaded portion to the non-threaded portion, wherein the resilient portion is connected to the ledge and projects axially away from the ledge. ### Claim 4 (depends on 1) The vehicle wheel hub lock assembly of claim 1, wherein the vehicle wheel hub lock nut comprises a flat annular end surface facing in the axial direction, wherein the resilient portion is located at the radial outer periphery of the annular end surface and wherein the resilient portion projects in the axial direction away from the annular end surface. ### Claim 5 (depends on 1) The vehicle wheel hub lock assembly of claim 1, wherein a safety washer constitutes the mating component. ### Claim 6 (depends on 5) The vehicle wheel hub lock assembly of claim 5, wherein the safety washer comprises an annular protrusion extending radially outwards from the safety washer, wherein the protrusion is configured to subject the resilient portion of the vehicle wheel hub lock nut to the external force when in the mated position. ### Claim 7 (depends on 1) The vehicle wheel hub lock assembly of claim 1, wherein at least a portion of the vehicle wheel hub lock nut is integrally formed by hot-formed steel. ### Claim 8 (depends on 1) The vehicle wheel hub lock assembly of claim 1, wherein the external force is configured to provide a prevailing torque of the vehicle wheel hub lock assembly in dependence of the vehicle wheel lock nut dimension, wherein the prevailing torque varies between 50 Nm and 230 Nm. ### Claim 9 (depends on 1) The vehicle wheel hub lock assembly of claim 1, wherein the resilient portion comprises a distal protrusion extending radially inwards towards the center of the central hole and configured to releasably hold the mating component when in the mated position. ### Claim 10 A vehicle comprising a hub lock assembly comprising: a hub lock nut comprising: a circumferential inner wall defining a central hole, the inner wall having a threaded portion; and at least one resilient portion; and a mating component with which the hub lock nut is arranged to be mated in a mated position; wherein the at least one resilient portion is adapted to be movable in a radial direction outwardly from the central hole when subjected to an external force provided by the mating component, the at least one resilient portion arranged to provide prevailing torque to the hub lock nut when subjected to the external force, the at least one resilient portion having an engagement area for receiving the external force, wherein the engagement area is located radially outwardly of the threaded portion in the mated position; and wherein the mating component comprises a protrusion extending radially outwards from the mating component and configured to subject the resilient portion to the external force in the mated position.
