Abstract
The utility model relates to an automobile engine piston, on which an anti-abrasion protective layer of micro-arc oxidation coating or restraining-arc oxidation coating is covered on the surface. The thickness of the anti-abrasion protective layer is 5 to 500micron. The utility model can reduce the vibration and noise of the engine cylinder, increase the amenity of motorbike riding and decrease the oil consumption of the engine.
Description
Technical field
The utility model relates to the piston of motor car engine, particularly a kind of magnesium alloy piston that can reduce the motorcycle engine of engine vibration and noise.
Background technique
Engine piston is one of most important parts on the motorcycle, motor is in running, piston is done the reciprocal motion of high speed in cylinder block, it mainly acts on: bear the active force that gas pressure caused in the cylinder 1., and these power are passed to connecting rod by wrist pin, rotate to promote bent axle.2. form the firing chamber jointly with cylinder head, cylinder wall.3. the sealing cylinder stops the outburst gas in the cylinder to scurry into crankcase.The material of the motorcycle engine piston that generally uses at present is aluminum alloy or steel, and some piston improves wear-resisting property at aluminum alloy or steel piston face hard chromium plating.Though these pistons have intensity height and the high characteristics of wear-resisting property, but its damping property relative with noise reduction a little less than, running up down the big and vibration frequency height of its vibration in motorcycle engine, not only influence the life-span and the ride comfort of motor, also the Security of influence driving.
Summary of the invention
The purpose of this utility model provides a kind of magnesium alloy piston of motorcycle engine.It can reduce the vibrations and the noise of motor, increases the riding comfort of motorcycle, can also reduce the oil consumption of motor.
The purpose of this utility model is achieved in that
The material of this piston is a magnesium alloy, and surface coverage has the differential arc oxidation layer or presses down the wear-resistant protective layer of arc oxide layer.
Differential arc oxidation layer or the thickness that presses down arc oxidation wearing layer are 5～500 microns.
The utility model piston adopts magnesium alloy materials, because magnesium alloy is lighter by 1/3rd than aluminum alloy, damping rate is tens times of aluminum alloy, so this piston can reduce the weight of motor greatly, helps the reduction of motorcycle fuel consumption.Because the suction of magnesium alloy is made an uproar, damping performance is better than aluminum alloy, therefore can reduce the vibration and the noise of motor, improve the travelling comfort of driving.The surface of piston press down arc oxidation wearing layer smooth surface and porous, it is more coarse that differential arc oxidation wearing layer surface presses down the arc oxidation relatively, same porous.The wearing layer porous has a part of lubricant oil of the storage of utilization, can reduce its friction factor when piston motion, improves wear resistance.This piston is a magnesium alloy, and its heat-conductive characteristic is higher than aluminum alloy, and the heat that can make motor makes the radiating effect of motor better rapidly to external diffusion, helps prolonging engine life
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2.The material of this piston 1 is a magnesium alloy, and surface coverage has the differential arc oxidation layer or presses down the wear-resistant protective layer 2 of arc oxide layer, and thickness is 5～500 microns.The differential arc oxidation layer that piston face covers or press down arc oxidation wearing layer and have the porous surface characteristic can store a part of lubricant oil, and when piston was done the reciprocal motion of high speed in cylinder block, owing to surface lubrication, its friction factor was little, so can improve its wear resistance.This piston is a magnesium alloy, and wherein the content of magnesium reaches 70%-95%, because the heat-conductive characteristic of magnesium alloy is higher than aluminum alloy, the heat of motor can make the radiating effect of motor better, long service life promptly to external diffusion.
Claims (3)
1. the magnesium alloy piston of a motorcycle engine is characterized in that: piston face is coated with the differential arc oxidation layer or presses down the wear-resistant protective layer of arc oxide layer.
