Rocker for a current collector of a vehicle
A rocker for a current collector of a vehicle includes at least one first contact strip connected to a first lever arrangement which is coupled to a first bearing device, and connected to a second lever arrangement which is coupled to a second bearing device, wherein the first bearing device and the second bearing device are connectable in an articulated manner to a current collector linkage, where a first torsion spring is fixedly connected to a lever of the first lever arrangement and non-rotatably via a displaceable bearing to the first bearing device or is connected non-rotatably via a displaceable bearing to a lever of the first lever arrangement and fixedly to the first bearing device, where the first torsion spring simultaneously forms a torque transmission device and a spring device such that a lightweight, compact and nevertheless robust arrangement for collecting current is thereby obtained.
