Background technique
The filtering lubricant oil system is one of very important system of motorcycle engine, its mainly act on be for the motorcycle engine moving element (as the cylinder head camshaft, bent axle, valve rocker etc.) provide lubricated, thereby make motive position form oil film, improve the working life of moving element thereby reduce friction, most of four-stroke engine for motor cycle is filtering mechanism for once, usually with crankcase as accumulator, machine oil filters by the oil filter screen that right crankcase covers, machine oil after the filtration is sucked by oil pump, be pumped out to again in the oil leab, arrive each lubricating component, moving element is lubricated by oil leab, because the boring ratio of oil filter screen is bigger, can only specific filtration resistance bigger aluminium bits and foreign material can't filter small particle, thereby can't guarantee to arrive the machine oil turbidity test of lubricant housings, from but the moving element rate of wear accelerate, reduce working life.
Summary of the invention
The purpose of this utility model provides further filtering lubricant oil, can filter small particle, can guarantee the turbidity test of lubricant housings machine oil, the motorcycle engine secondary filter mechanism that maintains easily, maintains.
The purpose of this utility model is achieved in that motorcycle engine secondary filter mechanism, be that the interior machine oil of crankcase is communicated with the engine component that a filter (oil filter screen), oil pump, need lubricate successively by inner oil duct, the machine oil path on the right crankcase cover machine oil chamber after the oil pump is provided with the secondary oil filter.
Above-mentioned secondary oil filter is by two end cap about the filter core, connect the center tube between the two end cap, be evenly equipped with circular aperture on the tube wall of center tube, 140-180 purpose fibrous filter net in the center tube outer wrapping constitutes, the upper end cap of filter core and compression spring, pressure spring, supports etc. are formed bypass valve, it is interior (under the complete stopping state of filter screen that machine oil enters filter core through fibrous filter net, machine oil overcomes pressure spring strength, enter support by the slit that forms between filter core loam cake and the compression spring, the support circumferencial direction has breach, machine oil enters in the filter core by breach), the center hole of lower end cap is the machine oil outlet.Machine oil in the filter core enters into oil duct by the filter core lower end cap.
Above-mentioned bypass valve is made up of annular spring pad, pressure spring, support, the filter core upper end cap is close in the upper-end surface of compression spring, be provided with spring between compression spring and the support, rack side wall has breach, so that machine oil flows in the filter core, normal condition is close to the filter core upper end cap at spring pressure lower spring pad, and machine oil passes through filter screen, the circular hole that sees through center tube wall enters in the filter core, enters the crankcase oil duct by the lower end cap center hole again.Only after the serious obstruction of filter screen, when machine oil can't see through filter screen and center tube wall circular hole and enters in the filter core, under the effect of oil pump, machine oil overcomes the pressure spring power under the compression spring, form the slit between compression spring and the upper end cap, machine oil enters in support and the filter core by this slit, enters in the crankcase oil duct by the filter core lower cover again.
The top of the upper end cap of above-mentioned secondary oil filter is provided with cover of oil filter, cover of oil filter is fastened on the end face of right crankcase cover, be provided with spring between cover of oil filter and the upper end cap, oil filter be close on the annular boss of right crankcase cover machine oil chamber by this spring.Machine oil path on the annular boss on the outlet of machine oil on the secondary oil filter and the right crankcase machine oil chamber sidewall is communicated with, and is provided with the O RunddichtringO between annular boss and the lower end cap, prevents lubricating oil leakage.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model increases the machine oil chamber at right crankcase cover, in the indoor secondary oil filter that is equipped with of machine oil, can the machine oil that pump in the oil pump be filtered once more, can filter out particle small in the machine oil, machine oil after guaranteeing to filter is in the machine oil turbidity test of each moving element (as cylinder head camshaft, bent axle, valve rocker etc.) lubricant housings, can reduce the wearing and tearing of moving element, increase its working life; Engine motor oil secondary oil filter is arranged on the right crankcase cover and maintains easily, maintains;
2, the bypass valve that is provided with on the secondary oil filter, avoiding fine particle to block the oil filter filter screen causes the machine oil can't be by causing the motor oil starvation, when machine oil can't pass through from the secondary oil filter, engine oil pressure overcomes the resistance of pressure spring, bypass valve is opened, machine oil directly from bypass valve by with oil delivery to the lubricant housings, thereby guarantee normal working of engine.
