Inventors include Blase, Bastian; Bhs, Florian; Bttner, Max; Stark, Thomas; and Tolksdorf, Andre.
The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: The invention relates to a current collector (2) for a road vehicle (1) for feeding traction energy from contact wires (5) of an electrical overhead line system. Said current collector comprises an articulated support linkage system (8), which can be rotatably supported on the road vehicle (1) via a base joint (15) and which supports two contact rockers (12, 13) rotatably mounted via a respective rocker joint (22). Each of the contact rockers (12, 13) has two contact strips (14) that are supported resiliently on the respective rocker joint (22) via leaf springs (23). A lifting device (17) is used to raise the support linkage system (8) from a rest position, in which the contact rockers (12, 13) are lowered close to the vehicle, into an operating position, in which the contact rockers (12, 13) are raised in order to establish electrical contact between the contact strips (14) and the contact wires (5). The leaf springs (23) are designed to be electrically insulating for potential separation between an overhead line potential, on which the contact strips (14) lie when the contact wires (5) are electrically contacted, and a vehicle potential, on which the support linkage (8) lies. According to the invention, a leaf spring (23) has at least one insulation barrier (32), which is upright on a surface (O) of the leaf spring (23) and transverse to a longitudinal direction (L) of the leaf spring (23). The longitudinal direction (L) points from a first fastening point (24) of the leaf spring (23), at which the leaf spring is connected to a contact strip (14), to a second fastening point (25) of the leaf spring (23), at which the leaf spring is connected to a rocker joint (22). As a result, the availability of the current collector (2) for supplying traction energy can be increased even in winter road conditions.
