Abstract

A composite wheel includes a rim, a connecting ring, a plurality of spokes and a flange all connected in sequence from the outside to the inside. One end of each spoke is provided with a thread, and the other end of each spoke is provided with a first mounting hole.

First claim

The invention claimed is:

1. A composite wheel, wherein the composite wheel comprises a rim, a connecting ring, a plurality of spokes and a flange all connected in sequence from an outside to an inside in a radial direction of the composite wheel, one end of each spoke of the plurality of spokes being provided with a thread, and another end of each spoke of the plurality of spokes being provided with a first mounting hole,
two ring grooves configured to accommodate the first mounting holes are provided in positions adjacent to a first axial surface and a second axial surface and on a radial outer side surface of the flange; threaded holes penetrating through the two ring grooves are uniformly provided in the first axial surface and the second axial surface of the flange corresponding to the two ring grooves, and multiple first mounting holes are inserted into the two ring grooves and connected by bolts passing through the first mounting holes and matching with the threaded holes;
a radial side surface of the connecting ring is uniformly provided with a plurality of through stepped second mounting holes, a radial outside hole diameter of each of the plurality of through stepped second mounting holes is larger than a radial inside hole diameter of each of the plurality of through stepped second mounting holes, a cylinder sleeve is pressed in the plurality of through stepped second mounting holes from an outside to an inside in a radial direction of the connecting ring, the cylinder sleeve is provided with an inner hole spherical surface and a cylindrical surface from an outside to an inside in a radial direction of the cylinder sleeve, the cylinder sleeve is further inserted with a locking sleeve, and the locking sleeve comprises a side wall spherical surface, an outer cylindrical surface and a threaded hole, wherein a radial outer side of the side wall spherical surface is matched with the inner hole spherical surface, the outer cylindrical surface is matched with the cylindrical surface, and the threaded hole is on a radial inside of the locking sleeve and matched with the thread of each spoke of the plurality of spokes;
the rim is fixedly connected to a radial outside of the connection ring.

2. The composite wheel according to claim 1 , wherein the radial side surface of the connecting ring is further provided with a first annular protrusion, and a second protrusion corresponding to the first annular protrusion is provided on a radial inner side surface of the rim, the first annular protrusion and the second protrusion being both provided with axial threaded through holes and are fixedly connected through a bolt.

3. The composite wheel according to claim 1 , wherein the threaded holes are symmetrically disposed on both the first axial surface and lower the second axial surface of the flange.

4. The composite wheel according to claim 1 , wherein a material of the rim comprises carbon fibers and a material of the plurality of spokes comprises a titanium alloy.
