Refuelling robot for motor vehicles

摘要

The device has a nozzle (13) and a tank filler socket with a docking device (12). The nozzle has radially movable locking bodies (27) which are stationary axially and in circumferential direction. In a radially outward position, the locking bodies engage positively under a circumferential collar on the docking device, thereby securing the nozzle. During docking/removal of the nozzle, the bodies are moved into a radially retracted position. A radial movement of the locking bodies is derived from a turning movement of the nozzle, via a spiral guide track on the end effector (14). The locking bodies are loaded radially outwards by a tension spring (32).
