Abstract
The invention discloses a crankshaft of an automobile. The crankshaft is made of improved alloys. The crankshaft, which is provided by the invention, has the beneficial effects that as the crankshaft adopts the improved alloys, the pressure resistance and toughness can be substantially improved and are twice to three times those of like products on the market.
Description
Technical field
The present invention relates to a kind of vehicle crank axle.
Background technology
Bent axle, it is the main rotary gadget of car engine, after loading onto connecting rod, upper and lower (back and forth) motion can accepting connecting rod becomes circulation (rotation) motion, be the important parts on engine, in prior art, its material is made up of structural carbon steel or spheroidal graphite cast iron mostly, but resistance to compression weak effect, comparatively easy fracture.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, provides a kind of vehicle crank axle.
To achieve these goals, technical scheme provided by the invention is: a kind of vehicle crank axle, described material is alloy, alloy composition according to parts by weight is: titanium carbide 25-35 part, tantalum carbide 25-35 part, aluminium sesquioxide 22-26 part, light rare earths 20-24 part, heavy rare earth element 20-24 part, rare earth elements 20-24 part, magnesium oxide 18-22 part, zinc oxide 18-22 part, Z 250 16-20 part, cobalt oxide 16-20 part, silica 1 5-18 part, peridotites ore deposit 14-16 part, concentrated molybdenum ore 14-16 part, cupric oxide 5-8 part, sodium-potassium eutectic 5-8 part, Manganse Dioxide 8-10 part, chromic oxide 8-10 part, antimonous oxide 3-5 part, plumbous oxide 3-5 part, triphane 12-15 part, beryl 12-15 part, boron trioxide 2-6 part, sulfurous gas 2-4 part, zirconium white 2-4 part.
Further, above-mentioned a kind of vehicle crank axle, described material is alloy, alloy composition according to parts by weight is: titanium carbide 30 parts, tantalum carbide 30 parts, aluminium sesquioxide 24 parts, light rare earths 22 parts, heavy rare earth element 22 parts, rare earth elements 22 parts, 20 parts, magnesium oxide, 20 parts, zinc oxide, Z 250 18 parts, cobalt oxide 18 parts, silica 16 parts, 15 parts, peridotites ore deposit, concentrated molybdenum ore 15 parts, cupric oxide 6 parts, sodium-potassium eutectic 7 parts, Manganse Dioxide 9 parts, 9 parts, chromic oxide, antimonous oxide 4 parts, 4 parts, plumbous oxide, triphane 14 parts, beryl 13 parts, boron trioxide 4 parts, sulfurous gas 3 parts, zirconium white 3 parts.
Beneficial effect of the present invention is: a kind of vehicle crank axle provided by the invention, because its material have employed the alloy of improvement, can increase substantially anti-pressure ability and toughness, is 2-3 times of commercial like product.
