Problems solved by technology

For engines using VVT, the VVT ​​oil supply hole is arranged in the middle of the front end of the cylinder head or on the timing cover. The former needs to thicken the wall thickness of the cylinder head, while the latter needs to increase the thickness of the timing cover. Generally speaking, these two structures The processing technology is complicated, and it has the disadvantages of increasing the length and weight of the engine
The increased length and weight of the engine will bring inconvenience to the installation and application of the engine, and will increase the cost

Abstract

The invention discloses an engine cylinder head bearing bracket. The engine cylinder head bearing bracket comprises a bearing bracket body (1), and a bearing pedestal, an oil-way channel, an oil-way oil feed hole and an oil chamber (10) which are arranged on the bearing bracket body (1), wherein the oil chamber (10) is connected with the oil-way channel; the oil-way channel leads to the bearing pedestal; the oil-way oil feed hole is formed on the oil-way channel; and the oil chamber (10) is connected with the oil-way channel through the oil-way oil feed hole. A cam shaft can be lubricated and oil is supplied for a variable valve timing system (VVT) through the oil-way channel on the engine cylinder head bearing bracket, without arranging a complex cam shaft lubricating oil way on the engine cylinder head, so the processing technique of the engine cylinder head is greatly simplified, the processing quality of the cylinder head is guaranteed, the structure of the cylinder head is simplified, the processing time of the cylinder head is saved, the whole oil way is smooth, and effective guarantee is provided for lubrication.

Description

Technical field [0001] The invention belongs to the field of automobile engines, and particularly relates to an engine cylinder head bearing bracket. Background technique [0002] With the rapid development of the automobile industry, engine performance requirements are getting higher and higher, and the weight of the engine and the lubrication system have a great influence on the engine performance. How to reduce the weight of the engine and improve the lubrication system is an important problem to be solved for us. At present, the lubrication of engine camshafts mainly relies on machining the oil passages leading to the bearing seat on the engine cylinder head, and lubricates the camshaft by lubricating the bearings. In recent decades, many countries, engine manufacturers, and scientific research institutions have invested a lot of manpower and material resources in the research of new technologies for variable valve timing (VVT) based on the requirements of improving the powe...
