Abstract
The utility model discloses an integrated natural gas engine cylinder head cover assembly which comprises a cylinder head cover, an oil seal, an ignition coil lining and a combined gasket. An ignition coil lining mounting hole is formed in the cylinder head cover, a plurality of lip sealing flanges are arranged on the inner surface and the outer surface of the oil seal, the outer surface of the oil seal and the ignition coil lining mounting hole of the cylinder head cover are sealed, the inner surface of the oil seal and the ignition coil lining are sealed, the space between the cylinder head cover and a cylinder cover is sealed by the combined gasket, a main body of the oil seal comprises a steel plate framework and elastic rubber, a middle layer of the combined gasket is made of hard low-carbon steel plates, and an upper layer and a lower layer of the combined gasket are made of foamed rubber. By the design of the multi-lip oil seal, machining deviation of the planeness of the ignition coil lining mounting hole can be offset, so that the ignition coil lining is easily mounted and effectively sealed, and the combined gasket can solve the problems that the whole cylinder head cover with a paper pad, planeness compensation is small, and lubricating oil easily leaks.
Description
Technical field
The utility model relates to a kind of integrated natural gas engine cylinder head cover assembly, belongs to automobile technical field.
Background technique
In prior art, large discharge capacity natural gas engine generally adopts the design of single cylinder list lid, and spark coil lining and cylinder head cover adopt the sealing of O type circle, adopt paper washer sealing between cylinder head cover and cylinder cap.If integral cylinder head cover adopts identical encapsulation scheme, because the planeness of processing stand fire coil mounting hole axis place plane is difficult to guarantee, it is excessive that cylinder head cover and cylinder head contacts sealing surface, easily occurs that cylinder head cover assembles difficult, the problems such as oil leak.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for prior art cylinder head cover encapsulation scheme, and a kind of integrated natural gas engine cylinder head cover assembly is provided.
For solving this technical problem, the utility model provides a kind of integrated natural gas engine cylinder head cover assembly, comprise cylinder head cover, oil sealing, spark coil lining and compound gasket, described cylinder head cover is provided with spark coil lining mounting hole, the inside and outside surface of described oil sealing is provided with multiple tracks lip seal flange, the outer surface of oil sealing and the spark coil lining mounting hole on cylinder head cover are realized sealing, the internal surface of oil sealing and spark coil lining are realized sealing, and compound gasket is realized the sealing between cylinder head cover and cylinder head.
The main body of described oil sealing consists of steel plate frame and elastic caoutchouc, and described steel plate frame and elastic caoutchouc sulfuration are integrated, and described lip seal flange is arranged on the elastic caoutchouc on the inside and outside surface of oil sealing.
Described compound gasket is three-decker, and mesosphere is hard low carbon steel plate, and upper and lower two-layer is bipeltate, and described hard low carbon steel plate and bipeltate sulfuration are integrated.
Beneficial effect: the utility model adopts the design of multiple lip type oil sealing to realize the sealing between cylinder head cover and spark coil lining, can make up spark coil lining mounting hole planeness machining deviation, is easy to install and realize effective sealing; Adopt compound gasket can solve integral cylinder head cover and use paper washer, planeness compensation is little, very easily occurs the problem of oil leak.
