RU52585U1 - UNIVERSAL WHEEL INSERT - Google Patents

Abstract

The utility model relates to the automotive industry, namely, to wheel devices allowing in emergency situations (puncture, rupture of the tire of the wheel, etc.) to continue the movement of the car to the nearest repair shop. The purpose of creating a utility model is to obtain a device (insert) fixed to the wheel disc, changing its internal configuration (profile) and not allowing the tire to “slip” from the wheel in an emergency. This goal is achieved in that each insert half-ring is made in the form of two parallel strips overlapping each other in width, with the possibility of a fixed position of one stripe relative to the other and equipped with support elements rigidly mounted on the inner surfaces of the strips, interconnected by a screw with left and right threads, and the number of support elements is unlimited.

Description

The utility model relates to the automotive industry, namely, wheel devices that allow in emergency situations (puncture, rupture of the tire) to continue the movement of the car to the nearest repair shop and is called a wheel insert.

There are various designs of inserts, wheel disk designs made already with an insert to prevent tire slipping from the disk, but they are either labor-consuming to manufacture, or complicated in design and installation, or designed for a specific type of wheel.

Bodgard Run-Flat system wheel rim designs are known (see Publication 1 (copy)), where the design is based on the insertion principle that prevents the tire from “slipping” off the disk when it is damaged.

However, the complexity and complexity of manufacturing discs (casting) limits their wide applicability.

Closest to the proposed technical solution is the wheel insert Armtype, which consists of two metal semicircles connected to each other in a ring located in the recess of the disk (see Publications 2, 3, 4) and not allowing the tire to “slip” from the disk and allowing to continue movement with damage.

To give rigidity to the metal ring when driving with a damaged tire, the elements of the ring (half ring) are made with supporting stampings abutting against the recess of the wheel disk.

The disadvantage of the design of this insert is the inability to use it for several sizes of wheels, because the dimensions of the recess of the disk, its width and depth, the angle of inclination of the inner surface for mounting the tire are different for each size, which requires a different width and design of the insert.

In the proposed utility model, the technical result is achieved in that each insert half-ring is made in the form of two parallel strips overlapping each other in width, having the possibility of a fixed position of one stripe relative to the other and provided with support elements rigidly mounted on the inner surfaces of the strips, interconnected by a screw with right and left threads, and the number of supporting elements is unlimited.

The essence of the utility model is illustrated by drawings, where:

The universal wheel insert (hereinafter referred to as the insert) consists of two half rings 1, provided with support elements 2 from the inside and connected by ties 3 (see Fig. 1), while the half rings of the insert consist of strips of inner 4 and outer 5 (see Fig. .3, 4).

At the bent ends of the inner strip 4, a screed 3 is installed (see FIG. 2), which consists of a clamping screw 6 with a nut 7, while the screw 6 passes through crackers 8 located in the bends of the inner strip 4.

The inner strip 4 (see Fig. 3) is made at the ends with curly grooves 9 into which the screw 6 and the tool for tightening the nuts 7 pass, and the length of the groove 9 is designed so that when tightening the edges of the groove abut against the body of the screw 6 and prevent extension strip ends 4.

In addition, the inner strip 4 is made with a cutout G for placement in it of part 11 of the upper strip 5, and at the ends of the lower strip 4 there is a system of holes 10 necessary for connection with the upper strip 5, when the insert is transformed into a wider or narrower one.

The upper strip 5 is equipped with a rigidly connected part 11, which is in the working position located in the cutout D of the lower strip 4, and the upper strip 5 is provided at the ends with a system of holes 12 (see Figs. 4, 5) necessary for its connection with the lower strip four.

On the inner surfaces of the strips 4 and 5, the supporting elements 14 and 15 of the support 2 are rigidly fixed, connected by a screw 16 to the right and left threads. The support 2 is located in the recess of the disk 13 (see Fig.6 and 7).

Such a constructive solution of the universal wheel insert allows it to be used for a certain range of wheel rim sizes, provides reliable transformation of the insert width without additional elements, and allows the use of the same insert on discs of different widths.

Fixation of the upper and lower strips can be carried out both mechanically (see photo 1-6), and by welding one strip to another.
