As a kind of preferred version, between described adjacent two arc mouldings, be coated with the second fibrage, this second fibrage wrap back-up block circumferential lateral surface and between the first fibrage being connected to adjacent two arc mouldings.
As a kind of preferred version, described first fibrage and the second fibrage are carbon fibre materials or glass fibre material.
As a kind of preferred version, described back-up block is metallic material or plastic material.
As a kind of preferred version, two end faces of described back-up block are all formed with recess and protuberance, and the recess of each end face and protuberance are connected with the foaming body of corresponding arc moulding.
As a kind of preferred version, described back-up block is I shape, and the two ends of two transverse parts of this back-up block are inserted in the foaming body of arc moulding of correspondence respectively, and the vertical portion of back-up block is located between the foaming body of adjacent two arc mouldings.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
By adopting non-fiber material to make back-up block, utilize back-up block to be located between adjacent two arc mouldings, back-up block can play good supporting role, make the overall construction intensity of product stronger, and production is more simple and convenient.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.

Detailed description of the invention
Please refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of first preferred embodiment of the utility model, include multiple arc moulding 10.
As shown in Figure 2, each arc moulding 10 all has foaming body 11 and the first fibrage 12, and this foaming body 11 is made up of expanded material, such as polyureas ester (Polyurethane; Be called for short PU) or polycarbonate (Polycarbonate; Be called for short PC) etc., there is the characteristic such as high tenacity and resistance to collision; This first fibrage 12 is coated on outside this foaming body 11, and this first fibrage 12 is carbon fibre materials or glass fibre material, has hard, the characteristic such as proportion is little, high temperature resistant and withstanding corrosion, in the present embodiment using carbon fiber as illustrative examples.
The plurality of arc moulding 10 joins end to end and is spliced to form one and takes turns mount structure, and the quantity of arc moulding 10 is not limited to them, and can be three, five, eight or ten etc., as long as the quantity of arc moulding 10 can connect into circular; And be all folded with back-up block 20 between adjacent two arc mouldings 10, two end faces of back-up block 20 are plane, this back-up block 20 is non-fiber material, in the present embodiment, this back-up block 20 is metallic material or plastic material, this back-up block 20 can provide support as rib for wheel frame, the second fibrage 30 is coated with between adjacent two arc mouldings 10, this second fibrage 30 wraps the circumferential lateral surface of back-up block 20 and between the first fibrage 12 being connected to adjacent two arc mouldings 10, this second fibrage 30 is carbon fibre materials or glass fibre material.
The manufacturing process that the present embodiment is described in detail in detail is as follows:
First, make the block expanded material of an arc, and envelope by the circumferential lateral surface of the first fiber cloth by block expanded material, according to said method, obtained multiple prefabricated arc moulding, then, multiple prefabricated arc moulding is spliced to form wheel mount structure, in the process of splicing, sandwiched one back-up block 20 between adjacent two prefabricated arc mouldings, then, use the second fiber cloth wrap back-up block 20 circumferential lateral surface and between the first fiber cloth being connected to adjacent two prefabricated arc mouldings; Then, the above-mentioned wheel frame result be spliced to form is put into mould be heating and curing, expanded material expanded by heating forms foaming body 11, the first fiber cloth and the second fiber cloth is extruded time expanded material expands simultaneously, make the first fiber cloth sizing formation first fibrage 12, and the second fiber cloth sizing formation second fibrage 30, and the second fibrage 30 and the first fibrage 12 combine.
