The invention aims to provide a damping connecting device and a valve chamber cover lid connecting structure using the same, which solve the problem of the noise and arrangement of plastic valve chamber cover lids. The damping connecting device comprises a body, wherein an umbrella flange surface which protrudes out of the periphery of the body is arranged on the middle part of the body; a cylindrical body is positioned on the lower part of the umbrella flange surface and is provided with a pit of which the opening is downward, and internal threads are formed in the pit; and a rubber damping cylinder is sleeved at the periphery of the cylindrical body. The valve chamber cover lid connecting structure using the damping connecting device comprises the damping connecting device, a valve chamber cover lid, a stud bolt, a nut, a cam shaft bearing base and an upper shaft cover of a cam shaft, wherein the bottom end of the stud bolt is fixed on the cam shaft bearing base; the upper shaft cover of the cam shaft passes through the stud bolt and is compressed by the nut on the stud bolt tightly; the cylindrical body arranged on the lower part of the damping connecting device passes through the valve chamber cover lid and is fixed on the top of the stud bolt.
Description
technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a connection structure of a valve chamber cover. Background technique [0002] As the requirements for engine performance are getting higher and higher, the weight reduction of the engine has a great impact on the performance improvement, and the use of plastic materials can effectively reduce the weight of the engine, especially the use of plastic valve cover, but The noise and layout problems caused by the use of plastic valve chamber cover also increase, which has a great impact on the service life of the valve chamber cover. Therefore, there is a need for a valve chamber cover bolt, which can reduce noise, facilitate the arrangement of components on the valve chamber cover, and ensure the service life of the valve chamber cover. Contents of the invention [0003] The object of the present invention is to provide a valve chamber cover connection...
