Problems solved by technology

[0005] A major disadvantage with these steps of installing / removing a split ring run-flat is that the ring does not always rotate simultaneously with (i.e. does not rotate as one with) the rim and tire during installation, which may make this installation difficult, and removing the ring from between the rim flanges can present many difficulties

Embodiment Construction

[0037] In this specification, the expressions "axially inner" and "axially outer" refer to the sides of the wheel rim facing the inner and outer sides of the motor vehicle, respectively, and the words "radially inner" and "radially outer" refer to the opposite A direction radial to the rim and close to the rim and a direction radial to the rim and away from the rim.

[0038] Figure 3 to Figure 6 The run-flat device 1 shown in is mounted on a one-piece asymmetric wheel rim 10 comprising a circumferential rim groove 11 abutting against an axially inner flange 12 of the rim 10 and an axially The outer flange 13 mounts a tire (not shown).

[0039] exist figure 1 In an example, the rim 10 includes an axially inner rim seat 14 and an axially outer rim seat 15, the rim seat 14 and the rim seat 15 are respectively used to receive the bead of the tire, and are respectively formed by the flange 12 and the adjacent The circumferential projection 16 is axially delimited as well as the...

Abstract

The present invention relates to a flat-running device intended for being fitted on an assembly mounted on a tubeless one-piece rim for an automobile, said mounted assembly including said device, and to a method for mounting and / or removing said mounted assembly. The device according to the invention (1) includes a ring (2) with a radially internal mounting surface for the device, intended to closely match the hollow section of the rim (11), the ring having an open structure with two ends held closely facing one another by a means (5) for clamping the ring. According to the invention, at least one transverse notch (6), the two edges and the bottom of which are located under one of the ends of the ring, is formed in at least one of said side portions (3a), forming a circumferential lip which projects axially from the corresponding side wall of the ring, which includes said recess and is suitable for wedging the ring in the hollow section of the rim, such as to enable, via said notch, transverse insertion of a tool (7) such as a lever between the rim and said mounting surface in order to facilitate the operations of mounting and / or removing the device on the rim.

Description

technical field [0001] The present invention relates to a run-flat device for fitting on a mounting assembly of the tubeless type having an integral rim for a motor vehicle, and to such a mounting assembly comprising said device and when A partial or total deflation enables a motor vehicle to travel a considerable distance at relatively high speeds, and relates to a method of mounting and / or removing said mounting assembly. Background technique [0002] For integral rims, known run-flat devices generally consist of a rigid support ring mounted within the tire tightly around the rim of the wheel. For example, the ring is formed as a single piece with relatively flexible sidewalls that may be continuous or alternatively formed as an open flexible piece (i.e. an open piece from which a portion is removed), or formed as at least two circular arcs or sectors. Rigid piece. [0003] Both patent documents FR-A1-2755905 and WO-A1-2008 / 132348 disclose a ring-type run-by device for a...
