Spacers for the beads of pneumatic tires

The innovation relates to a spacer for the beads of pneumatic tires to be stacked, the recesses for receiving the having.

Uster vulst toe is understood here as the part of the two bulges facing the adjacent soap bead or the tire cavity.

The known spacers of this type are wave-shaped, they extend over the entire circumference of the tire. This ensures that the soaps cannot experience any undesirable deformations when they are stacked, i.e. when they are more axially loaded, but these spacers are expensive to purchase, because they have the appropriate dimensions for the soap .

The innovation is based on the task mentioned at the beginning To improve spacers so that sowing would be much easier and can be produced more cheaply, but this is their job meet the spacing well.

Uo ensure the spacing, wexdeia Toa cea spacers according to the innovation several arranged distributed over the Heifenursfang. The innovation is based on the knowledge axts, caiss with one sufficient compressive rigidity or terminal rigidity of the spacers a completely adequate abstinence Ia Werein Esit den ¥ tülstkernen located in the soap beads can be achieved, with the spacers for particularly strong 3ela.stTingen, e.g. for shock loads elastic deformations possible, but then as Molded body?. B. by, a suitable Prof From this with low weight a sufficient hinged wing can be obtained.

Further details of the innovation are based on the drawing explained, in which an exemplary embodiment of the innovation is shown is »which should preferably kojaaen for use.

Show it:

However, the spacer consists of a beating "and biegsiestes _f slightly elastically deformable plastic. It is made in one piece and designed as a body made in a Torrn.

According to FIG. 1, the spacer is generally U-shaped designed. The two T-foraigea legs in cross section 1 are about the actual distance that brings about Bridge 2 connected to each other.

The outer surfaces on the side. 3 of the legs 1 are adapted to the bead toe 4 of the tire. For this reason there is also a in the extension of the web 2. Projection 5, so that at both ends of the spacer there is a trough to a! Attack the bulge toe h »

The legs 1 have an S-shaped cross section such that they form a girder of the same flexural strength in the area of the contact surface of the bulge toe h. The free end 6 of the legs 1 is not ribbed, however, strongly rounded in such a way that the ends 6 of the two legs i which belong together are inclined towards one another. These rounded ends 6 facilitate

the pushing on or insertion of the AbstanÄulterv if this be guided by a movement in the direction of arrow 7 between the two beads.

The web 2 has a Boppel-x-Frofile. His ^ uerechfliti; is or its straps and its web are larger towards the central axis a of the web Z in order to achieve a strength-wise favorable material distribution here too.

In Figure 1, a spacer is shown. She understands that in practice several spacers according to Figure 1 are evenly distributed over the circumference of the tire. It finds so no single arrangement, but always a multiple arrangement application.
