Background technique
Before the utility model is made, in prior art: traditional water cooled engine lubrication system oil pump is drawn lubricant oil from the crankcase bottom oil sump, enter oil pump through strainer and oil suction duct, after oil pump pressurization again through the pressure limiting device pressure regulation, a small amount of unnecessary oil is got back to the bottom oil sump after the pressure regulation, all the other major parts enter the body main oil gallery, enter the oil filter filtering that is installed on the body again, after filtering is intact again to body main bearing hole and body camshaft bearing hole, oily inclined oil hole of air on the crankshaft rear end main journal again enters the rod journal horizontal hole in the body main bearing hole, one the tunnel goes to the two ends of lubricated rod journal, another road enters the inclined oil hole of air on the crankshaft front end main journal, the main bearing hole that comes lubrication box to cover enters case lid camshaft bearing hole from the case lid main bearing hole through vertical oilhole again.There is following problem in this kind lubricating system:
1, the oil that pumps of oil pump just directly enters the oil filter filtering without cooling, and oil temperature does not have controlled, fragile machine oil and fastness.
2, the lubricant oil at case lid main bearing hole and camshaft bearing hole place is that the inclined oil hole of air of lubricant oil on the crankshaft rear end main journal from the casing main bearing hole enters the rod journal horizontal hole, one the tunnel goes to the two ends of lubricated rod journal, another road enters the inclined oil hole of air on the crankshaft front end main journal, enter the main bearing hole on the case lid, the lubricated case lid main bearing of a part, a part enters case lid camshaft bearing hole from the case lid main bearing hole through vertical oilhole.This lubricating system on case lid main bearing hole and the camshaft bearing hole lubricated Path too long, intermediate distributary is many, bent axle is again a revolving part, be subjected to the influence of rotary centrifugal force, lubricant oil is subjected to certain additional drag from rod journal to crankshaft main journal, generally speaking be exactly the amount that enters the lubricant oil of case lid main bearing hole be not very sufficient, thereby the amount of lubricant oil that enters case lid camshaft bearing hole is just more inadequate, and it is not very abundant causing the lubricated of case lid main bearing hole and camshaft bearing hole.
3, the lubricant oil that enters the rod journal two ends is only from the body main bearing hole, and also divides one the road to the case lid main bearing hole, causes the lubricated also insufficient of rod journal.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of amount abundance that can make the lubricant oil that enters the case lid main bearing hole, can make the amount of the lubricant oil that enters case lid camshaft bearing hole also relatively more sufficient, guarantee the lubricated very sufficient engine lubrication system in case lid main bearing hole and camshaft bearing hole.
Main solution of the present utility model is achieved in that
The utility model is mainly formed a seal space by crankcase cover 33 and body 34, lubricant oil is installed in the seal space bottom, be crankcase oil sump 1, bent axle is housed in seal space, bent axle is provided with two main journals and a rod journal, on body 34 and crankcase cover 33, main bearing hole 24 is set, 28 and camshaft bearing hole 23,27, also be provided with hydraulic tappet oil inlet hole 22 on the body, on crankcase cover 33 junction planes, strainer mounting hole 31 is set, suction passage 9, oil pump low-pressure cavity 10, hyperbaric chamber 11, inner and outer rotors mounting hole 16, structures such as pressure limiting valve opening 12, side arrangement machine filter device seat mounting hole 32, strainer parts 2 are fastened in the crankcase cover 33 junction plane respective aperture, inside and outside rotor in oil pump 15, limiting valve spring and steel ball 14,13 are contained in crankcase cover 33 respective aperture by oil pump cover plate 17, oil filter seat 7 is fastened in the crankcase cover 33 side respective aperture, machine filter device seat 7 is connected with machine oil cooler 6 by machine oil pipe 4, and is connected with oil filter 3 by swivel nut 8.
On body 34 and crankcase cover 33, be provided with main oil gallery 26,30 and divide oil duct 25,29, lubricant oil enters the branch oil duct by main oil gallery, enters the main bearing hole 24,28 and 23,27 interior and body 34 hydraulic tappet oil inlet holes 22 places, camshaft bearing hole of body 34 and case lid 33 by minute oil duct.
Be provided with inclined oil hole of air 18,21 on two main journals of bent axle and lead to rod journal two ends oilhole 20, and in rod journal, converge, guarantee that rod journal has sufficient lubricating oil by rod journal horizontal hole 19.
For increasing safety in utilization, engine oil pressure warning device 5 has been installed on body main oil gallery 26.
The utility model is compared with existing lubrication system and is had the following advantages:
1, in the crankcase cover side arrangement oil filter seat attachment face and mounting hole, oil filter seat is installed on the crankcase cover side, oil filter seat is connected with machine oil cooler by two machine oil pipes, is connected with oil filter by swivel nut.The machine oil that pumps after the oil pump pressurization enters machine filter device seat, again to machine oil cooler with oil filter is cooled off and filtering, enter the main oil gallery of case lid and body after filtering is intact again, the machine oil that pumps of oil pump has not only obtained filtering like this, also obtained cooling before the filtering, oil temperature is under control, and machine oil can Yin Gaowen and produced rotten.
2, all be furnished with main oil gallery and branch oil duct on body and the case lid, the oil that oil pump pumps enters crankcase cover and body main oil gallery respectively after cooling and filtering, enter each minute oil duct from main oil gallery again, through each minute oil duct enter in the main bearing hole of body and case lid and the camshaft bearing hole and other pressure of body is located with oily (hydraulic tappet oil inlet hole).The amount that enters the lubricant oil in body and case lid main bearing hole and camshaft bearing hole like this is equal sufficient, can not cause case lid main bearing hole and place, camshaft bearing hole lubricants capacity inadequate because of the influence of lubricated Path too long and crankshaft rotating centrifugal force.
3, all there is inclined oil hole of air to pass to the rod journal oilhole on the crankshaft two end main journal, be that body and case lid main bearing hole all enter the rod journal oilhole by the inclined oil hole of air on the crankshaft main journal, two-way comes oil to converge in rod journal by the rod journal horizontal hole, and the lubrication ratio of rod journal is more abundant like this.
4, because the engine oil pressure warning device has been installed, increased the safety in utilization of motor on the body main oil gallery.
