Wheel brake e.g. vehicle-wheel disk brake, has web-sections drawn on initial points of evolvents on same evolvent circle, where evolvents are placed on same circle with angular displacement, and roller bodies are rolled on web sections

摘要

The brake has a roller bearing with a circular segment shaped bearing surface (20), a non-circular bearing surface and roller bodies (24, 25) arranged between the bearing surfaces and supported at the bearing surfaces. The non-circular bearing surface has two separate web-sections in the form of evolvents, where the non-circular bearing surface is a roller web. The web-sections are drawn on initial points of the evolvents on the same evolvent circle, where the evolvents are placed on the same evolvent circle with an angular displacement. The roller bodies are rolled on the web sections.
