Good evening together, I don’t think I had asked that yet, but the other day I got a book about racing suspensions, which says that racing cars don’t have rubber in the chassis. In the case of road cars, between bolts and eyelets, the handlebars are lubricating agents (captivated by a rubber cuff) and a layer of rubber or polyurethane. I thought it was a bending joint. Lubricants push themselves in the long run, and must be re-verted by the wide movement of the suspension. Polyurethane could be a little feathers there. So if you drive quietly over a smooth road. At the first pothole then the Hafabreibung breaks off and perhaps some polyurethane out (wear). Or is it only about dirty hauschdammung without any synergy? I still dream of the wear-free suspension. I like the bending joints in the F1 and the these mirrored leaf springs in carriages. With such a full-fledged chassis with Stabi and Lenkun g there are so many joints. The interlocking rear axle is a real ray of light. Do you also like the leafed headdresses with 2 joints per spring and the 5 handlebars rear axles? And then I read a patent, where someone proposes a ball-bearing ball joint. But that’s not really true, is it? On the 2 wheel the steering axles are ball-bearing. I would like to have such a light-winged steering on the 4 wheel. Does this have any car? MfG Arne
