Abstract
The invention discloses an easy-to-radiate wheel made of composite materials. A metal insert with heat conductivity coefficient is arranged on the installation surface directly contacting with a wheel made of composite materials where the wheel is closest to a brake disc. The metal insert is embedded into the wheel and integrates with the wheel by serving as one part of the wheel. The metal insert is made of aluminum alloy or copper alloy. The easy-to-radiate wheel made of composite materials has the advantages that the wheel made of composite materials can radiate effectively during use, the problem of thermal fatigue failure caused by poor radiating of the wheel made of composite materials is solved, reliability and the service life of the wheel made of composite materials are improved.
Description
Technical field
The present invention relates to heat abstractor, especially possess the composite material automobile parts of better heat-sinking capability.
Background technology
Composite material has lightweight, high-intensity feature, is widely used in the fields such as aerospace, track traffic.Along with the development of technology, must have increasing composite material and be used to manufacture weight-saving parts.Along with people are to automobile product fuel saving or save the raising that electric energy requires, and the attention to environmental protection of national governments and enterprise, are necessary to introduce new material and are used for the Design and manufacture wheel of environmental protection more.Composite material is a kind of good selection, and low but composite material and metallic material are compared coefficient of thermal conductivity, radiating effect is poor.In vehicle traveling process, brake disc operating temperature is about between 200 ℃-300 ℃, can reach 500 ℃ continuously under descending operating mode.The operating temperature that is transmitted to wheel mounting surface is about 120 ℃-150 ℃, and peak value can arrive 180 ℃.Long-time reliability and the service life of working at this temperature and can make composite material wheel generation thermal fatigue and greatly reducing composite material wheel.In order to promote the application of composite material wheel, be necessary the problems referred to above to solve.The present invention proposes a solution, can effectively address the above problem.
Summary of the invention
In order to solve general composite material wheel, be difficult for heat radiation and then the problem that thermal fatigue affects reliability and service life occurs, the wheel of making as carbon fiber enhancement resin base composite material or engineering plastics, thus in vehicle traveling process, heat constantly gathers to can not get effectively discharging wheel was lost efficacy.The invention provides a kind of new solution and be used for head it off.
The present invention solves the problems of the technologies described above adopted scheme: attachment face nearest with brake disc at composite material wheel and that directly contact wheel arranges its metal abaculus that coefficient of thermal conductivity is high, metal abaculus adopts pre-buried mode embedded composite material wheel, as the part of wheel, becomes as a whole with wheel.Described metal abaculus is aluminum alloy, copper alloy.
According to heat dissipation capacity size, metal abaculus thickness is set.In use, first the heat that brake disc is delivered to wheel is delivered on metal abaculus composite material wheel, and the coefficient of thermal conductivity of metal abaculus own is larger, has good permeability of heat and thermal diffusivity.By being delivered to heat in composite material part after metal abaculus heat radiation within the range of temperatures that can bear for a long time.With this, solve composite material wheel and be difficult for the problem that reliability reduces and shorten service life that heat radiation causes.
The invention has the beneficial effects as follows: composite material wheel in use can efficiently radiates heat, solved the bad thermal fatigue failure problem causing of composite material wheel heat radiation, improved the reliability of composite material wheel and extended service life.
Accompanying drawing explanation
Fig. 1 is a kind of composite material wheel mechanism schematic diagram that is easy to heat radiation of the present invention.
In figure: 1-metal abaculus; 2-composite material wheel; 3-brake disc.
The specific embodiment
The present invention will be further described with the specific embodiment by reference to the accompanying drawings.
As shown in Figure 1, the present invention is comprised of metal abaculus 1 and composite material wheel 2.First the heat that during automobile brake, brake disc 3 produces is transmitted to metal abaculus 1, is transmitted to composite material wheel 2 again, thereby solves wheel heat dissipation problem after 1 heat radiation of metal abaculus.
The present invention guarantees that the wheel that composite material is made can keep good thermal diffusivity in vehicle traveling process, also just guaranteed that composite material wheel in use avoids thermal fatigue failure, strengthened the reliability of composite material wheel, extended service life, and fuel saving and energy resource consumption, be conducive to environmental protection.
