Problems solved by technology

In addition, the vibration of the engine will also cause the oil to generate air bubbles. Because the air bubbles are compressible, it will affect the accuracy of the pressure in the main oil passage, resulting in a high air content in the oil in the oil pan, which will affect the normal operation of the engine.

Embodiment Construction

[0010] An oil pump cover, including a cover body 10, the overall weight is relatively light, the cover body 10 is covered on the oil pump 20, and the cover body 10 and the oil pump 20 are enclosed to accommodate the oil pump sprocket 21 and the slave machine. The cavity of the oil pump chain 22 bypassed on the oil pump sprocket 21, the joint of the cover body 10 and the oil pump 20 is sealed, and assembled together with the crankshaft timing sprocket 30 and the chain tensioner 40, the oil pump sprocket 21 and the crankshaft timing sprocket 30 drive the oil pump 20 to rotate under the action of the oil pump chain 22, as figure 1 , 2 shown.

[0011] to combine figure 1 , 2 , the cover body 10 includes a riser 11 , and the center of the riser 11 is provided with a protrusion 15 for covering the fixing bolt of the oil pump sprocket 21 . A sidewall 12 is extended along the direction perpendicular to the surface of the riser 11 at the edge of the riser 11 , and the peripheral pr...

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 [0001] The invention relates to the field of automobile engines, in particular to an oil pump cover. Background technique [0002] The lubrication system is an important part of the engine. Its main function is to supply a sufficient amount of clean lubricating oil with an appropriate temperature to each friction surface to reduce friction loss and wear of parts, so as to ensure the power, economy, reliability and durability. The oil pump is the most important part in the lubrication system. Its function is to provide sufficient pressure and flow of oil for the lubrication system to ensure that each friction part is fully lubricated and avoid damage to related pressure-bearing parts, ensuring that the engine can run smoothly. Normal operation under various working conditions. [0003] At present, most engines adopt the form that the oil pump is directly driven by the crankshaft, and the engine wears a lot. In addition, it is necessary to ensure a reliable s...
