摘要： The present invention relates to a current collector for rapid charging systems for urban and suburban buses or heavy vehicles that utilize an electric or a hybrid drive. The articulated connection of an upper arm (13), a tension rod (20) and a drive arm (12) forms a kinematics based on the four-bar linkage, wherein the upper arm (13) is connected to a head (14) that is guided to a charging channel of a stationary charging station located at bus stops or end stations.

摘要： The subject matter of the present invention is a contact head for a current collector adapted for charging a vehicle equipped with an electric drive in rapid charging systems, comprising at least two oppositely arranged electrical contacts mounted on at least two pressing elements that are rotatably disposed on at least one axis of rotation with a limited angle of rotation and having at least one resilient element for pressing the electrical contacts against at least two conductive strips of a compatible contact device of a charging station, said conductive strips being arranged on opposite sides of the contact head and through which the power supply voltage is applied, wherein the pressing elements are formed as opposing arms (2, 3) - a first arm (3) and a second arm (2); at least one electrical contact (5) is provided on the first arm (3); at least one electrical contact (6) is provided on the second arm (2); at least one axis of rotation (4) around which the arms (2, 3) rotate is aligned essentially in the direction of the longitudinal axis of the vehicle, parallel to the direction of vehicle movement; wherein to the second arm (2), on an axis (13) parallel to the at least one axis of rotation (4), a third arm (8) is rotatably attached through a resilient element, on said third arm (8) an earthing contact (9) is arranged, the earthing contact (9) being in an extended position and protruding beyond the boundary of the head (1), so that when connecting the head (1) to the charging station, the earthing contact (9) contacts the conductive strip as the first of all contacts; wherein on one of the arms (2, 3), from the side facing the conductive strips, a communication contact (7) is provided. Moreover, the present invention also relates to a method of establishing electrically conductive connection between the charging station and the contact head (1).
