As improvement of the technical scheme, offer on described wheel carrier and the position that wheel seat is connected and be equipped with an annular boss, described rotating support groove is positioned on the annular boss, the junction arranged outside of above-mentioned wheel carrier and wheel seat has outer wall, there is certain space between described annular boss and the described outer wall, do not need packing material, therefore can save the production material, reduce production costs.
As further improvement in the technical proposal, the outside face of described annular boss evenly is provided with all around and is no less than three strengthening rib, and above-mentioned strengthening rib can strengthen the intensity of annular boss, prevents that annular boss from damaging when bearing bigger load.
Further, the bottom of described rotating support groove offers be used to the mounting hole that allows bolt pass, after above-mentioned bolt passes described mounting hole, be connected with the circular shaft that is rotationally connected again, thereby wheel carrier and wheel seat are coupled together, and when preventing that people from mentioning case and bag, wheel carrier breaks away from from wheel seat.
Further, the bottom of described wheel carrier is provided with two symmetrical connecting arms, offer the reinforcement groove of strengthening its intensity on the described connecting arm, above-mentioned reinforcement groove can strengthen the intensity of connecting arm, can be when cardan wheel bears bigger load, prevent the connecting arm fracture damage, guarantee the service life of cardan wheel.
The beneficial effects of the utility model are: because wheel seat of the present utility model adopts integrated structure with the circular shaft that is rotationally connected that is fixedly mounted on the bottom, mode by injection mo(u)lding can process wheel seat simultaneously and be fixed on its bottom and the downward circular shaft that is rotationally connected that extends, thereby do not need independent separate machined wheel seat and the circular shaft that is rotationally connected, also no longer need the wheel seat after processing and the circular shaft that is rotationally connected are fitted together, make that the production of cardan wheel is simpler, improved production efficiency, reduce productive costs, thereby strengthened the competitiveness of society of enterprise.
