Description
Technical field
The present invention relates to vehicle arrangement technical field, be specifically related to engine lubrication system supercharging pressurizer。
Background technology
Lubricating system is for blood vessels like people electromotor, and its importance is self-evident。Any electromotor variable part, crankshaft group and piston/cylinder part are when running, inevitably produce friction and heat, and the Main Function of oil circulation is exactly reduce the frictional dissipation of variable part, crankshaft group and piston/cylinder and take away too much heat, allow variable part, crankshaft group and piston cylinder physical ability steady operation at a proper lubrication condition and temperature。Particularly crank connecting link part is always up the soul of all electromotors, exactly because there being crank connecting link, just reciprocal piston movement is converted into utilizable rotary motion。Therefore the lubrication of crankshaft group is particularly important。In prior art, crankshaft group part is because being not provided with lubricating system supercharging pressurizer, namely being not provided with crankshaft bearing oil sealing, when oil circulation, machine oil leaks from crankshaft bearing, not only lubricating oil low oil pressure, and can not pressurize, it is impossible to the key components such as sufficiently effective lubrication variable part, crankshaft group, piston/cylinder and crank connecting link, very easily cause bent axle locking, the serious consequences such as crank-pin sinters, scuffing of cylinder bore。
Summary of the invention
It is an object of the invention to overcome problems of the prior art and deficiency, it is provided that a kind of " engine lubrication system supercharging pressurizer "。Supercharging pressure-holding apparatus structure is reasonable in design, cost is low for this, lubricating oil oil pressure can be brought up to 2.5MPa from 0.2MPa, pressurize 1.5-2MPa, it is effectively improved electromotor variable part, crankshaft group and piston/cylinder Pulvis Emolliens thermal effect, guarantee electromotor reliability of operation and stability, significantly reduce the power attenuation of electromotor。

Further technical scheme is, described bearing enclosure 1 is made up of the lip 11 being structure as a whole and skeleton 12, and lip 11 and skeleton 12 interference fit of fitting with bearing inner race 21 and bearing seal groove 22 respectively is connected。
Further technical scheme is, material respectively fluorubber and steel material used by described lip 11 and skeleton 12。
Further technical scheme is, the magnitude of interference between lip 11 and bearing inner race 21 is 0.3mm。
Supercharging principle of keeping pressure: the machine oil that lubricating oil pump pumps is to have certain oil pressure, when pressure oil enters main oil leab 32, if without this supercharging pressurizer, machine oil will directly spill from the gap between crankshaft bearing 2 inner ring and outer ring, not only can not keeping oil pressure, oil pressure also constantly can reduce because of the leakage of machine oil。After having had this supercharging pressurizer, bearing enclosure 1 and crankshaft oil seal 31 have sealed the machine oil to reveal, not only ensure pump and pump the pressure of machine oil, and from 0.2MPa, machine oil hydraulic can be brought up to 2.5MPa, pressurize 1.5-2MPa, it is ensured that the lubricating system that each assembly of shape coupled engines is fully good。
The present invention compared with prior art has the advantage that
1, present configuration is reasonable in design, cost is low, lubricating oil oil pressure can be brought up to 2.5MPa from 0.2MPa, pressurize 1.5-2MPa, it is effectively improved electromotor variable part, crankshaft group and piston/cylinder Pulvis Emolliens thermal effect, guarantee electromotor reliability of operation and stability, significantly reduce the power attenuation of electromotor。
2, because of main improvement opportunity be bearing enclosure 1 successively with crankshaft bearing 2, crankcase left box body 4 interference fit connects, the magnitude of interference between lip 11 and bearing inner race 21 is 0.3mm, the magnitude of interference is moderate, guarantee the positive sealing of bearing enclosure 1 and crankshaft bearing 2, when effectively preventing oil circulation, leak from crankshaft bearing 2, lubricating oil oil pressure is brought up to 2.5MPa from 0.2MPa, pressurize 1.5-2MPa, it is effectively improved electromotor variable part, crankshaft group and piston/cylinder Pulvis Emolliens thermal effect, eliminate because crankshaft bearing 2 lubricating oil leaks bent axle locking, crank-pin sinters, the problems such as scuffing of cylinder bore。
3, because of material respectively fluorubber and steel material used by lip 11 and skeleton 12, fluorubber mechanical strength and wearability are high, there is good heat-resisting, oil resistance, operating temperature-20 DEG C to+200 DEG C, high temperature resistant up to 300 DEG C, bearing enclosure 1 good sealing effect, long service life, improve sealing property and the reliability of crankshaft bearing further, enable machine oil to smoothly enter crank connecting link parts, and then make various engine components obtain sufficient lubrication,, it is ensured that electromotor reliability of operation and stability。
