Electric current collector for transmitting electrical energy between an electrical line and a vehicle

An electric current collector assembly for transmitting electrical energy between an electrical line and a vehicle comprises a base frame 16 for mounting on the vehicle, a lower support arm 20 pivotally connected to the base frame 18, an upper support arm 22 pivotally connected to the lower support arm 20, a current collector head 40 pivotally connected to the upper support arm 22, a guide 46 for guiding a follower 48 in relation to the upper support arm 22 along a path 49, a connecting rod 50 pivotally connected to the follower 48 and to the current collector head, and guide bar 60 or other transmission means for converting a rotational motion of the upper support arm 22 in relation to the lower support arm 20 into a motion of the follower 48 in relation to the upper support arm 22 along the path 49. This arrangement provides a reliable positioning of the collector head 40, which remains horizontal irrespective of the actual position of the assembly within an operational range, and an improved aerodynamic and aero-acoustic performance of the current collector particularly at high speed.
