Definitions
- the present invention relates to an axial securing of the wheel bearing for pedestrian-controlled vehicles according to the preamble of patent claim 1.
- Pedestrian-guided vehicles in particular industrial trucks, have a drawbar and a drive wheel which can be steered by means of the drawbar.
- the drawbar and drive wheel are arranged at a distance from the longitudinal center plane of the vehicle in the lateral direction.
- the known bearings of the wheel hub drives commonly used are rarely located directly in alignment with the drawbar pivot point and centrally to the impeller surface due to the small installation space, this area being considered optimal. In this case, it is very difficult due to the small space to provide optimum axial security for the wheel.
- the commercial circlips, which are provided with assembly or disassembly holes are not useful for this application due to the small space.
- the present invention has for its object to provide an axial securing of the wheel bearing in a pedestrian-controlled vehicle, which effectively prevents the impeller from the wheel hub drive triggers.
- the axial securing device according to the invention should be simple in construction and cost-effective to produce with maximum reliability. This object is solved by the features of the claim.
- the mounting in alignment with the drawbar pivot point and centrally to the impeller surface and to secure it axially by means of at least two snap rings.
- the snap rings can slip out of their grooves despite bias, due to forces resulting from, for example, lateral forces or shocks that are introduced from the outside, the housing parts are extended in the direction of the snap rings.
- the extension takes place in such a way that the gap over the snap rings is smaller than the grooves in which the snap rings are arranged by simple machining. This ensures that the circlips are held in their grooves even under extreme conditions, so that the safety of the vehicle is guaranteed.
- the bearing 2 is arranged in alignment with the drawbar fulcrum 1 and centrally with respect to the impeller surface, wherein the axial securing of the bearing 2 is effected by two snap rings 3, which are held in grooves 7. Furthermore, the housing parts 4, 5, the one Form gap 6 on the snap rings 3, according to the invention extended in the direction of the snap rings 3, that the gap 6 on the snap rings 3 is smaller than the grooves 7, in which the snap rings 3 are held. In this way, an axial securing of the impeller is ensured even under extreme conditions, since even in the event that the snap rings 3 lose their bias due to external force, a secure holding the snap rings 3 in the grooves 7 due to the inventive design of the gap 6 is given.
