AI Technical Summary
Technical Problem
Existing pantograph designs for electric and hybrid-electric vehicles suffer from wear issues due to abrasion and sudden contact outbreaks with overhead power lines, which are not adequately addressed by current damping and cross-section reduction methods.
Method used
A pantograph with a supporting linkage carrying contact rocks, each equipped with multiple junctions along the contact piece, distributing traction current through several connection cables to reduce heating and wear, optimized by symmetrical junction placement.
Benefits of technology
Reduces wear on contact pieces by minimizing heat generation at the contact points, preventing slipping and extending the lifespan of the pantograph components.

Abstract
The invention relates to a pantograph (3) for a road vehicle (1) with an electric traction drive (2) for supplying traction energy from an overhead line system. It comprises an erectable support frame (6) which can be rotatably supported on the road vehicle (1) via a base joint (7) on the vehicle side and carries two contact rockers (11) rotatably connected via a rocker joint (10) on the contact wire side. Each of the contact rockers (11) carries at least one contact strip (15) extending in a transverse direction (Y) of the vehicle, which has a contact element holder (16) and an electrically conductive contact element (17) mounted therein with a contact surface (18) for a contact wire (4) resting on the contact strip (15). The sliding strips (15) of each of the contact rockers (11) can be electrically connected to a traction drive (2) via power cables (26) laid along the support rod (6).By routing a power cable (26) along the support rod (6) to each contact rocker (11), which branches into several connecting cables (23) in the area of the respective contact rocker (11) to each of the at least one slip ring (15), each of which is electrically connected to the contact piece holder (16) of this slip ring (15) at a connection point (22), the wear of the contact pieces (17) can be reduced.
