Abstract
The utility model discloses a kind of built-up wheel, wheel spoke adopts magnesium alloy materials.Rim for automobile wheel adopts carbon fiber composite material.The two is independent, parallel shaping, is then assembled together and becomes wheel entirety.Magnesium alloy materials and carbon fiber composite material use rivet interlacement.Wrought magnesium alloy spoke and carbon fiber composite material rim combination realize wheel light and quantize, and solve the forming process difficulty faced when bi-material is used alone, the problem that production efficiency is low, cost is high, quality conformance is poor simultaneously.
Description
Technical field
The utility model relates to a kind of lightweight built-up wheel, especially magnesium alloy and carbon fiber composite material built-up wheel.
Background technology
Along with people are to automobile product fuel saving or save the raising of power requirements, and national governments and enterprise are to the attention of environmental protection, and automobile must lightweight further in design.The light weight effect of wheel on automobile is equivalent to the 5-6 of vehicle body doubly, therefore manufactures and designs lightweight wheel that is safer, environmental protection and becomes particularly important and can reach the effect of getting twice the result with half the effort.
Current application is aluminum-alloy wheel the most widely.Magnesium alloy and carbon fiber composite material are compared with aluminum alloy materials, and the above two density is about 2/3rds of aluminum alloy, and can meet wheel design performance requriements.But magnesium alloy and carbon fiber composite material are used for separately manufacturing and designing wheel has very high technology difficulty, cost is high, homogeneity of product is poor, quality is wayward, and mass industrialized production (production efficiency is low) cannot be realized, so at present only application and not exclusively ripe to some extent on the high-grade sport car of only a few.This situation limits the application of this bi-material on the one hand, also counteracts that the development of lightweight wheel on the other hand.
In order to advance automotive light weight technology, be necessary to solve the problems referred to above.The utility model proposes a solution, can effectively solve the problem.
Summary of the invention
In order to solve the magnesium alloy and the wayward problem of molding carbon fiber composite material difficulty in process, high cost and product design that advance and run in automotive wheel weight reduction process, the utility model provides a kind of built-up wheel.
The utility model solves the problems of the technologies described above adopted scheme: a kind of built-up wheel, comprise spoke, wheel rim, spoke is wrought magnesium alloy spoke, and wheel rim is carbon fiber composite material wheel rim, and it is overall that wrought magnesium alloy spoke and composite material wheel rim adopt rivet to form wheel.
Front adopts magnesium alloy forging formation to solve to be used alone wheel rim position when magnesium alloy manufactures and designs wheel fills type difficulty, easily produces the problem of defect, mechanical property instability, and meanwhile the lower density characteristic of magnesium alloy is able on wheel, play lightweight advantage.Wheel rim adopts carbon fiber composite material to solve the problem being used alone spoke and core wheel difficult forming when carbon fiber composite material makes wheels, easily producing defect, quality conformance difference, and carbon fiber composite material greatly reduces for the manufacture of technology difficulty during circular pieces and can give full play to the characteristic of its high-strength light.The two be combined inferior position separately complementary and respective advantage can have been given full play to.
The beneficial effects of the utility model are: wrought magnesium alloy spoke and carbon fiber composite material rim combination realize wheel light and quantize, and solve the forming process difficulty faced when bi-material is used alone, the problem that production efficiency is low, cost is high, quality conformance is poor simultaneously.
Accompanying drawing explanation
Fig. 1 is schematic diagram after the utility model built-up wheel Standard.
Fig. 2 is schematic diagram before the utility model built-up wheel Standard.
In figure: 1-magnesium alloy spoke; 2-carbon fiber composite material wheel rim; 3-rivet.
Detailed description of the invention
With detailed description of the invention, the utility model is described further by reference to the accompanying drawings.
As shown in Figure 1, built-up wheel comprises magnesium alloy spoke 1 and carbon fiber composite material wheel rim 2, rivet 3.Magnesium alloy spoke 1 adopts Forging Technology shaping, and carbon fiber composite material wheel rim 2 adopts resin transfer molding technique.The two is combined by multiple rivet 3, becomes wheel entirety.Thus realize wheel light quantification, solve the forming process difficulty faced when bi-material is used alone, the problem that production efficiency is low, cost is high, quality conformance is poor simultaneously.
By the effect of this kind of combined structure design, while ensureing that wheel reaches light weight effect, to reduce costs, raising efficiency and reliability, save motor vehicle fuel and energy resource consumption, be conducive to environmental protection.
