Filling system for robot-capable filling of a vehicle with fuel
First Claim
1. A filling system for an automated fueling of a motor vehicle, comprising:
- a filler nozzle;
a filler neck having a docking extension provided with a central opening, said docking extension adapted for being mounted on a filling side of the vehicle and being rotatable via an upper section around an axis of symmetry for operating an opening and closing process of a tank closure of the motor vehicle;
wherein said docking extension has an outlet end which forms a positive connection between the filler nozzle and the docking extension;
locking bodies mounted on said filler nozzle, said locking bodies being radially movable but axially and circumferentially fixed;
a circumferential bead arranged on said docking extension, wherein said locking bodies positively grip beneath said circumferential bead when urged radially outward away from a longitudinal centerline of said filler nozzle, thus securing the filler nozzle in an axial direction; and
wherein said locking bodies are movable into a radially retracted position when said filler nozzle is docked and undocked.

Abstract
A filling system for robot-capable filling of a vehicle with fuel has a filler nozzle and a tank filler neck on which a docking extension provided with a central opening is mounted on the filling side. The extension is rotatable by an upper section around the axis of symmetry for opening and closing a tank closure. The filler nozzle is dockable by its end on an outlet side, forming a positive connection between the filler nozzle and the docking extension, with positive elements in the form of teeth distributed around its circumference. The teeth have a hub section and interlock with one another positively when the filler nozzle is ready for filling. In order to achieve functionally reliable docking of the filler nozzle on the filler neck of the vehicle fuel tank and to permit rapid undocking of the filler nozzle from the filler extension, a locking body, urged radially outward by a pretensioning spring, is provided on the outlet side of the filler nozzle. The locking body is guidable relative to an upwardly adjacent positive element of the filler nozzle along a guide path that runs in the circumferential direction, and is inserted completely into the filler nozzle by rotating the filler nozzle at one end of the guide path. The body also projects radially out of the filler nozzle at the other end in such fashion that its bevelled surface abuts underneath the matching positive element of the docking extension beneath which it grips.
