Abstract
The invention provides a novel engine tappet which comprises the following raw materials in percentage by weight: 30-45 percent of carbon fiber, 53-68 percent of aluminum-magnesium alloy and 1.8-2.1 percent of rare earth. A preparation method for the novel engine tappet comprises the steps of weaving the high-intensity carbon fibers into fiber cloth, putting the fiber cloth into a die, and then pouring the aluminum-magnesium alloy in a melted state into the die for forming. According to the invention, the weight of the novel engine tappet is lighter than that of an existing engine tappet by about 60-80 percent, and the strength is enhanced by multiple times; through compact treatment, the novel engine tappet has the advantages of high intensity, high-temperature resistance, corrosion resistance, small specific gravity, excellent forming technology, environment friendliness, attractiveness and low cost as well as capabilities of reducing the technical programs, easily obtaining materials, facilitating industrialization and realizing recycling.
Description
Technical field
The present invention relates to matrix material Application Areas, particularly relate to a kind of new work engine tappet.
Background technology
The world is in green energy resource auto age, and automotive light weight technology problem is all put in the first place by various countries automotive engineering technician.Next be durable in use, fuel oil is few, load-carrying is many, traveling is fast, safe and reliable, comfortable.And all seeking the electric power energy automobile of replacing fuel oil; to preserve our planet the common homeland of the mankind; in the world today; a lot of developed country all passes by and experiencings decocting of atmospheric pollution haze misery, and can administer haze process and electromobile truly needs again very long years.Human knowledge is one of source of haze to motor vehicle fuel, want motor vehicle to adopt minimum oil consumption and power consumption, first need automobile self lightweight, each automobile is heavily relieved to 300 ~ 350 kilogram weights by 2.8 tons, 1.2 tons are heavily relieved to 130-150 kilogram, or less than 100 kilograms.If continue to use motor vehicle fuel function to need to continue lightweight on the light-weighted basis of car body, engine weight is reduced, need engine body (tappet, connecting rod, bent axle, rocking arm), all to alleviate respectively, finally just can reach engine lightweight, oil consumption reduces object.
Existing automobile engine tappet many employings metal or alloy material is made, because material is than great, cause the total quality of engine heavier, add the energy consumption of vehicle, and existing other materials cannot meet the high temperature resistant and crocking resistance requirement of engine tappet, when existing engine temperature raises, tappet can expand because of the effect of expanding with heat and contract with cold, valve clearance is diminished, affect tappet normally to use, work-ing life is short, how to found a kind of sturdy and durable, coefficient of thermal expansion and contraction is little, long service life, high temperature resistant, the new new work engine tappet of rub resistance, make automotive light weight technology, the green new energy motor industrialization of final realization, become the target that industry is badly in need of improving.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of new work engine tappet, makes its coefficient of thermal expansion and contraction little, long service life, high temperature resistant, wear-resistant, light specific gravity, and technique is simple, and material source is easy to get.
For solving the problem, the invention provides a kind of new work engine tappet, comprise carbon fiber that weight ratio is 30%-45%, aluminum magnesium alloy that weight ratio is 68%-53% and weight ratio be the rare earth of 1.8-2.1%, its preparation method is, high-strength carbon fiber is woven into cloth and puts into mould, then the aluminum magnesium alloy of molten state is poured in mould, machine-shaping.
Further, the weight ratio of described carbon fiber is 31-38%, and the weight ratio of described magnalium is 60-67%, and the weight ratio of described rare earth is 1.8-2.1%.
Further, the weight ratio of described carbon fiber is 32-34%, and the weight ratio of described magnalium is 64-66%, and the weight ratio of described rare earth is 2%.
Adopt this new work engine tappet to alleviate about 60-80% than the existing tappet of existing engine tappet weight ratio, and intensity improve several times, has high strength again through densified, high temperature resistant, corrosion-resistant, light specific gravity, moulding process is good, reduce processing sequence, environmental protection, material source is easy to get, inexpensive, facilitate industrialization, the advantage such as can be recycled.
Tappet coefficient of thermal expansion and contraction of the present invention is little, and valve clearance can not be changed, and improves matrix material tappet work-ing life with this.
Tappet of the present invention is applicable to motor vehicle tappet used application, has good using value especially, accelerate green novel energy source vehicle industrialization process to large-scale load truck.
