Safety device for a vehicle wheel

摘要

A safety device (10) for a vehicle wheel (12), the device securing the attachment elements (16) of the rim (18) of the wheel onto a hub (14), wherein the device (10) includes elements (20) for blocking the rotation of the attachment elements and elements (21) for supporting the blocking elements on the attachment elements, the rotation-blocking elements including female parts (24) and at least one peripheral wall (26, 26I, 26E) against which the female parts abut when rotating, wherein at least a portion of the attachment elements receives a female part, the supporting elements (21) include an upper wall (36) that covers the attachment elements provided with the female parts, and the upper wall (36) blocks the translation of the female parts along the attachment elements, wherein the device includes elements (22) for rigidly connecting to the wheel, and the rigid connection is mechanically locked.

主权项

1. A safety device (10), for a wheel (12) of a vehicle, that secures attachment elements (16) of a rim (18) of said wheel (12) on a hub (14), said safety device (10) comprising:
means (20) for locking in rotation said attachment elements (16); means (21) for holding said locking means (20) on the attachment elements (16), said means (20) for locking in rotation consisting of female parts (24) and at least one peripheral wall (26, 26I, 26E) against which said female parts (24) abut in rotation, with at least one portion of the attachment elements (16) accommodating at least one female part (24), the holding means (21) comprising at least one upper wall (36) covering the attachment elements (16) that are equipped with said female parts (24), said upper wall (36) blocking, directly or by means of another part, the translational movement of said female parts (24) along the attachment elements (16); and means (22) for engagement with the wheel (12), wherein said engagement is locked mechanically, wherein the engagement means (22) comprise at least one lower wall (58, 58-1, 58-2) held against the rim (18) by at least one attachment element (16), with said lower wall (58, 58-1, 58-2) being inserted between said element (16) and the rim (18), and wherein a mechanical locking means (62) is provided that locks, in rotation and in translational movement, each attachment element (16) that is used for the creation of engagement means (22) thereby holding each lower surface (58, 58-1, 58-2) against the rim (18).
