Description
Technical field
The present invention relates to automobile manufacturing field, especially a kind of Vehicular energy-saving oil pump.
Background technique
Oil pump is the heart of engine lubrication system, directly affects working life and the energy-saving effect of overall performance, the especially motor of motor.Existing rotor-type oil pump mainly is comprised of oil pump casing, internal rotor, external rotor and pump cover etc., is provided with filler opening, oil-feed tank, oil outlet on the oil pump casing, goes out oil groove, and filler opening communicates with oil-feed tank, goes out oil groove to communicate with oil outlet; Internal rotor is fixed on the rotor shaft with key or pin, is directly or indirectly driven by crankshaft gear, and external rotor is driven by internal rotor and rotates in the oil pump casing hole; The motion mode of rotor pump is the same with internal gear pair; The center arranged off-centre of internal rotor and external rotor, internal rotor drives external rotor and rotates in the same direction together; Internal rotor lacks a tooth than external rotor, has so just guaranteed that inner and outer rotors rotates in the same way asynchronously.
Desirable job requirement is motor car engine to oil pump: under the slow-speed of revolution, satisfy minimum fuel delivery; When high rotating speed, guarantee minimum oil pressure.At present, usually the fuel pump for vehicle rotary speed property is, at certain oil temperature, necessarily go out under the oil pressure, oil pump fuel delivery size increases with the increase of rotating speed, and the two is linear.
For guaranteeing that motor is under various oil temperatures, and after component wear, bearing play increase, machine oil still keeps certain pressure, the supply capability of oil pump is in design much larger than actual demand, although in determining the process of oil pump supply capability, carried out a large amount of optimal design, when motor reaches certain rotating speed, still have a large amount of machine oil and directly release by pressure-limit valve and return fuel tank.Common oil pump fuel delivery when high rotating speed will exceed 2 times～3.5 times of actual demand amount, and this explanation common machine oil pump can't all reach optimized design in all rotating speeds of motor.In order to satisfy the low speed demand of motor, just must cause the ability of oil pump under the high rotating speed of motor superfluous, the principal contradiction that exists in the at present oil pump design that Here it is, unnecessary lubricant oil directly releases from pressure-limit valve and returns fuel tank, causes engine power consumption increase, the aging acceleration of machine oil.
