The invention relates to a current collector (2) for an electrically driven road vehicle (1) for feeding traction energy from a two-pole overhead line system. The current collector comprises an articulated support rod (4) which, on the trolley line side, supports a rocking device (11) having at least one contact slide (12) for each contact pole, and, on the vehicle side, has a bottom hinge (5) for supporting on the road vehicle (1). The lifting drive (22) is coupled to the support rod (4) in such a way that the contact slide (12) can be lifted into an upper contact position. According to the invention, the support rod (4) is formed in a pantograph-like manner with a lower arm (6) and an upper arm (8) connected thereto by means of an elbow joint (7). In this case, the swing device (11) has a swing box (14), which has an upper cross-member (15) and a lower cross-member (16), which are connected to a rotary joint (19) in the middle by means of a central support (17) and on both sides by means of side supports (18). The upper arm (8) is connected to the intermediate support (17) on the trolley line side by means of a swing hinge (20). The contact slide bars (12) of the two contact poles are symmetrically supported on the swing box (14) relative to the middle support column (17). In this way, a current collector (2) is provided, by means of which a uniform contact force between the contact slide (12) and the slide wire (3) of the overhead line system can be achieved with a simpler design.
本发明涉及一种用于电驱动的道路车辆(1)的集电器(2),用于从两极的架空线路设备中馈入牵引能量。该集电器包括铰接的支承杆(4),该支承杆在滑接线侧支承对于每个接触极具有至少一个接触滑条(12)的摇摆装置(11),并且在车辆侧具有用于支承在道路车辆(1)上的底铰链(5)。升降驱动器(22)与支承杆(4)耦联,使得接触滑条(12)可以提升到上面的接触位置中。根据本发明,支承杆(4)被受电弓式地构造有下臂(6)和与该下臂通过肘铰链(7)连接的上臂(8)。在此,摇摆装置(11)具有摇摆箱(14),该摇摆箱具有上横梁(15)和下横梁(16),该上横梁和下横梁在中间通过中间支柱(17)并且在两侧分别通过侧支柱(18)连接在转动铰链(19)上。上臂(8)在滑接线侧通过摇摆铰链(20)与中间支柱(17)连接。两个接触极的接触滑条(12)相对于中间支柱(17)对称地支撑在摇摆箱(14)上。由此提供一种集电器(2),利用该集电器在结构更简单的情况下能够实现在接触滑条(12)和架空线路设备的滑接线(3)之间的均匀的接触力。
