1. A contact apparatus for a rapid-charging system for electrically driven vehicles, wherein the contact apparatus serves to form an electrically conductive connection between a vehicle and a stationary charging station having a charging contact unit, said contact apparatus adapted to be mounted on a roof of an electrically-driven vehicle and to be positioned beneath the charging contact unit, comprising:

  • a contact device contactable with the charging contact unit, wherein the charging contact unit forms a concave receiving opening;

    a positioning device positioning the contact device relative to the charging contact unit, wherein the positioning device has a pantograph or a swing arm positioning the contact device in the vertical direction relative to the charging contact unit; and

    a contact element support having a plurality of bolt shaped contact elements elastically mounted on the contact element support, wherein each of the plurality of contact elements contact a corresponding one of a plurality of charging contact elements disposed within the receiving opening of the charging contact unit so as to form contact pairs,wherein the positioning device includes a linear transverse guide arranged at a distal end of the pantograph or of the swing arm and the contact element support is arranged on the linear transverse guide in a freely displaceable manner, the linear transverse guide comprising first and second guide tracks and the contact element support comprising first and second sliding legs, each of the first and second sliding legs including a sliding surface adapted to be received on and to slide along the guide tracks, the linear transverse guide being configured to adjust a position of the contact element support transversely relative to the charging contact unit or to the direction of travel of the vehicle to compensate for transverse movement of the vehicle.
