Abstract
The invention relates to an oil pump cover which comprises a cover body, wherein the cover body is covered on an oil pump; the cover body and the oil pump enclose a cavity which is used for containing an oil pump chain wheel and an oil pump chain bypassing the oil pump chain wheel; and the junction of the cover body and the oil pump is provided with a seal. The cover of the invention is covered on the oil pump chain wheel and used for isolating the oil pump chain wheel from the engine oil in the drain pan; and when the engine operates, the cover can reduce the air content of the engine oil caused by collisions and frictions between the operating oil pump chain wheel and the engine oil in the drain pan, thereby ensuring the reliable operation of the engine. The seal is arranged between the cover body and the oil pump to further prevent the oil pump chain wheel rotating at high speed from stirring up a great amount of engine oil and bubbles in the drain pan, thereby reducing the air content of the engine oil and ensuring the normal operation of the engine.
Description
Technical field
The present invention relates to the motor car engine field, especially a kind of oil pump cover cap.
Background technique
Lubrication system is the important constituent element of motor, it mainly acts on is to supply the clean lubricant oil with proper temperature of capacity to each friction surface, the reduce friction loss and the wearing and tearing of part are with power character, Economy, reliability and the durability of assurance internal-combustion engine.Oil pump is most important parts in the lubrication system, its function is the machine oil that enough pressure, flow are provided for lubrication system, to guarantee that each friction member obtains lubricating fully and avoiding relevant pressure part is caused damage, guarantee that motor can normally operation under various operating modes.
At present, most of motor adopts oil pump directly by the form of crank-driven, and the motor abrasion is bigger, needs to guarantee the reliable sealing between oil pump and the bent axle in addition.In order to remedy this shortcoming, More and more factories adopts oil pump to be suspended on oil sump inside now, adopts the chain-drive setting type, and this scheme has solved this problem effectively.Yet, because when engine running, oil pump chain gear high speed rotating, oil pump chain gear, chain and machine oil clash into mutually, rub, and have produced a large amount of bubbles.In addition, the vibration of motor also can make machine oil produce bubble, because bubble has compressibility, therefore can influence the accuracy of main oil gallery pressure, causes the machine oil air content in the oil sump very high, influences the normal operation of motor.
Summary of the invention
The object of the present invention is to provide a kind of oil pump cover cap that can reduce air content in the engine motor oil.
For achieving the above object, the present invention has adopted following technological scheme: a kind of oil pump cover cap, comprise lid, lid is located on the oil pump, enclose the cavity of the oil pump chain that is used to hold the oil pump sprocket wheel and walks around from the oil pump sprocket wheel between lid and the oil pump, the junction of lid and oil pump is provided with sealing.
As shown from the above technical solution, cover cap of the present invention is to be used for covering on the oil pump sprocket wheel, play the effect that the machine oil in oil pump sprocket wheel and the oil sump is kept apart, when motor moves, can reduce because of the machine oil in running of oil pump chain gear and the oil sump collides mutually, fricative machine oil air content, guarantee the engine reliable operation.Simultaneously, between the lid of cover cap and oil pump, sealing is set, can further stops the oil pump sprocket wheel when high speed rotating, stir a large amount of machine oil in the oil sump, produce a large amount of bubbles, thereby reduce the air content of machine oil, guarantee the normal operation of motor.

Fig. 2 is the explosive view isometric drawing that the present invention assembles the back assembly;
Fig. 3 is the structural representation that locating stud cooperates with positioning hole among the present invention.
Embodiment
A kind of oil pump cover cap, comprise lid 10, overall weight is lighter, lid 10 is located on the oil pump 20, enclose the cavity of the oil pump chain 22 that is used to hold oil pump sprocket wheel 21 and walks around from oil pump sprocket wheel 21 between lid 10 and the oil pump 20, lid 10 is provided with sealing with the junction of oil pump 20, and together assemble with crankshaft timing sprocket 30 and chain tensioning device 40, oil pump sprocket wheel 21 and crankshaft timing sprocket 30 are under the effect of oil pump chain 22, drive oil pump 20 rotations, as shown in Figure 1, 2.
In conjunction with Fig. 1,2, described lid 10 comprises riser 11, and the center position of described riser 11 is provided for the projection 15 of the fixing bolt of mulch-laying machine oil pump sprocket wheel 21.The edge of riser 11 is provided with sidewall 12 along extending perpendicular to the direction of riser 11 plate faces, and the peripheral profile of sidewall 12 roughly takes the shape of the letter U.Sidewall 12 is towards a side at oil pump 20 places, form the hole of passing for oil pump chain 22 16 between the top of riser 11 and the sidewall 12, offer seal groove 14 on the edge of sidewall 12, the shape of the sealing strip 23 that is provided with on the shape of sealing groove 14 and the oil pump 20 matches, make oil pump 20 and lid 10 form certain space, separate with the machine oil in the oil sump, the bubble that makes oil pump sprocket wheel 21 produce when high speed rotating is enclosed in the limited space, prolong the time that machine oil enters oil pump 20 filler openings, reduced the machine oil air content of motor main oil gallery.Also be provided on the sidewall 12 lid 10 is fixed on positioning device on the oil pump 20.
In conjunction with Fig. 1,2,3, integral body of the present invention is made of plastics, and described positioning device is for evenly being arranged in a plurality of locating studs 13 on lid 10 sidepieces 12 at interval, and the number of described locating stud 13 is three.The parallel to an axis of the length direction of locating stud 13 and oil pump sprocket wheel 21 wheel shafts, the 13a of non-return portion is set on the head of locating stud 13, and this head is offered cross groove from middle mind-set edge, this groove is divided into four parts with the middle and upper part of locating stud 13, to guarantee that locating stud 13 has certain tension force, offer the positioning hole 24 that matches with locating stud 13 on the oil pump 20.Because plastics have certain elasticity, under normal condition, these four parts forming locating stud are separated, when assembling, four parts are pushed to the centre, with 24 intact cooperations of positioning hole of offering on the oil pump 20, simultaneously, the 13a of non-return portion that is provided with on the head has guaranteed the reliability that connects.This structure has not only been saved the quantity of bolt, and assembles simplely, easy installation and reliable, has reduced the development cost of motor effectively.
In sum, core of the present invention is to design a lid that covers on oil pump, and this lid can be kept apart the machine oil in oil pump sprocket wheel and the oil sump, when motor moves, can reduce the machine oil air content, guarantees the engine reliable operation.Simultaneously, this life adopts plastic material, has further reduced weight.
