  • Rocker arm for a valve train of an internal combustion engine, and method for the non-cutting production of an arm from steel sheet
    Patent number: 11225884
    Abstract: A rocker arm has two side walls and two webs which run transversely with respect to the side wall. The webs connect the side walls to one another on end-side sections, wherein a valve stem support is configured on one of the webs, and a spherical cap is configured on the other web. A cam roller is arranged in a roller pocket which is delimited by the webs and the side walls. The cam roller is mounted rotatably on a roller axle which is fixed in the side walls. Projections are arranged within the roller pocket such that they are spaced apart from the respective web to guide the cam roller. The projections extend from the side walls in the direction of the cam roller to form guide surfaces which interact with end surfaces of the cam roller.
