Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
As shown in fig. 1, the utility model provides an electric vehicle wheel hub, which comprises a wheel rim 1, a mounting sleeve 2 and a plurality of radial plates 3 uniformly distributed along the circumferential direction, wherein the mounting sleeve 2 is coaxial with the wheel rim 1, the mounting sleeve 2 is fixedly arranged on the wheel rim 1 through the radial plates 3, one end of the radial plates 3 is welded and fixed on the mounting sleeve 2, and the other end of the radial plates 3 is welded and fixed on the wheel rim 1;
With reference to fig. 3, the mounting sleeve 2 is fixedly provided with a plurality of reinforcing bars 21 (in this embodiment, the number of the reinforcing bars 21 is not less than 5) which are uniformly distributed along the circumferential direction, the end portions of the reinforcing bars 21 far away from the mounting sleeve 2 are fixedly welded on the rim 1, and each reinforcing bar 21 is provided with two radial plates 3, that is, the number of the radial plates 3 is twice that of the reinforcing bars 21; the wheel webs 3 are fan-shaped, and the corresponding two fan-shaped surfaces of the wheel webs are perpendicular to the axis of the rim 1, as shown in fig. 1, two wheel webs 3 on the same reinforcing bar 21 are symmetrically arranged on two sides of the reinforcing bar 21, that is, the two wheel webs 3 on the same reinforcing bar 21 are completely overlapped along the axial projection of the rim 1;
Furthermore, two flanges 31 are symmetrically arranged on the web 3, one of the radii of the rim 1 is parallel to the length direction of the flanges 31 (because there are numerous radii of the rim 1, not all the radii are, but one of the radii is), that is, the extending end of each flange 31 passes through the axis of the rim 1; with reference to fig. 6, the included angle between the folded edge 31 and the web 3 is β, the β value is 90 °, the folded edge 31 and the web 3 are in transition through an arc surface, and two ends of the folded edge 31 are also welded to the mounting sleeve 2 and the rim 1 respectively; in actual production, the hem 31 may be integral with the web 3, the hem 31 being formed by punching with a punch.
With reference to fig. 4 and 6, a plurality of first through holes 4 are uniformly distributed on the reinforcing strips 21, second through holes 5 corresponding to the first through holes 4 one to one are formed in the radial plates 3, namely, the first through holes 4 formed in each reinforcing strip 21 correspond to the second through holes 5 formed in each radial plate 3 one to one, the first through holes 4 are identical to the second through holes 5 in aperture, the radial plates 3 are fixed on the reinforcing strips 21 through bolts 6 in the through holes, in order to guarantee the installation strength, 2 or more first through holes 4 are formed in each reinforcing strip 21, and in addition, the bolts 6 need to be connected for anti-loosening treatment so as to prevent looseness generated after the hub is used for a long time.
when the wheel hub is used, the mounting sleeve 2 is welded on the wheel rim 1 through the reinforcing strips 21 in a welding mode, then two radial plates 3 are mounted on each reinforcing strip 21, the radial plates 3 are fixed on the reinforcing strips 21 through the bolts 6, and finally the two ends (the two ends including the folded edges 31) of the radial plates 3 are respectively welded on the mounting sleeve 2 and the wheel rim 1 in a welding mode, so that a complete wheel hub is formed. As shown in fig. 6, two radial plates 3 are arranged on each reinforcing bar 21, so that the two radial plates 3 and the reinforcing bars 21 are integrated, and the cross section of each radial plate 3 and the reinforcing bar 21 form an i-shaped structure, and compared with the single arrangement of the radial plates 3, the i-shaped structure realizes three-dimensional support and improves the support strength; in addition, the arrangement of the folded edge 31 forms a reinforcing rib on one hand, the strength of the spoke plate 3 is improved, and on the other hand, the supporting position is further expanded, so that the I-shaped supporting space is further enlarged, and the supporting strength is further improved.
