Abstract (en)
[origin: WO2023001511A1] The invention relates to a current collector (2) for an electrically powered vehicle (1) for feeding traction energy from a two-pole overhead line system. The current collector comprises an articulated support linkage (4), which, on the contact wire side, supports a rocker assembly (11) having at least one contact strip (12) per contact pole and, on the vehicle side, has a base joint (5) for support on the road vehicle (1). A lifting drive (22) is coupled to the support linkage (4) in such a way that the contact strips (12) can be lifted into an upper contact position. According to the invention the support linkage (4) is formed like a pantograph with a lower arm (6) and an upper arm (8) connected to the lower arm via an elbow joint (7). The rocker assembly (11) has a rocker frame (14) having an upper transverse beam (15) and a lower transverse beam (16) which are connected centrally by a centre strut (17) and on each end side by a lateral strut (18) on swivel joints (19). The upper arm (8) is connected on the contact wire side to the centre strut (17) via a rocker joint (20). The contact strips (12) of the two contact poles are supported on the rocker frame (14) symmetrically with respect to the centre strut (17). In this way a current collector (2) is provided by which, with a simpler construction, a consistent contact force can be achieved between contact strips (12) and contact wires (3) of the overhead line system.
