Abstract
The invention discloses a sealing mechanism with a single air cylinder cover and an entire valve cover. The mechanism comprises the single air cylinder cover (1), an irregular rubber sealing ring (2), an irregular rubber sealing ring (3), a gas distribution top board (4), the entire valve cover (5) and a cover plate (6). The gas distribution top board (4) is arranged on the single air cylinder cover (1); the entire valve cover (5) is arranged on the gas distribution top board (4); the single air cylinder cover (1) and the gas distribution top board (4) are sealed through the irregular rubber sealing ring (2); the gas distribution top board (4) and the entire valve cover (5) are sealed through the irregular rubber sealing ring (3); and the cover plate (6) is arranged on the entire valve cover (5). The mechanism disclosed by the invention is simple in structure. By additionally arranging the structure of the gas distribution top board, the reliability, generality and interchangeability of the air cylinder cover can be improved. Meanwhile, the difficulty in design and technique can be reduced.
Description
Technical field
The invention belongs to Diesel Engine Technique Field, be specifically related to a kind of monomer cylinder head Integral air valve chamber cover sealing mechanism.
Background technique
At present, the multicylinder engine of overhead-cam design commonly used adopts the structure of integrated cylinder cover and integrated type cyclinder head cover more.Under this structure,, can guarantee that distribution device is installed and the assembly precision of work, make that distribution device can reliably working because cylinder head is whole pattern.Because cylinder head is whole pattern, greatly reduces the seal complex property of cylinder head top structure.Adopt Integral air valve chamber cover to match with it, only integral sealing is carried out in outside between cylinder head and the cyclinder head cover and get final product.And this structural type piece cylinder head design difficulty is big, complex structure; The casting technique difficulty strengthens, and cost is high, be unfavorable for producing in batches; Versatility, interchangeability are poor.
Summary of the invention
The invention provides a kind of monomer cylinder head Integral air valve chamber cover sealing mechanism; Solve the be complementary sealing of structure of monomer-type cylinder head and Integral air valve chamber cover, also solved the problem that the distribution device installation precision that adopts the monomer cylinder head to exist is difficult to guarantee simultaneously.
The present invention can realize through following technological scheme: a kind of monomer cylinder head Integral air valve chamber cover sealing mechanism; Comprise monomer cylinder head 1, special-shaped rubber seal 2, special-shaped rubber seal 3, distribution top board 4, Integral air valve chamber cover 5, cover plate 6; On monomer cylinder head 1, be provided with distribution top board 4; Distribution top board 4 is provided with Integral air valve chamber cover 5; By special-shaped rubber seal 2 sealings, by special-shaped rubber seal 3 sealings, be provided with cover plate 6 above the Integral air valve chamber cover 5 between distribution top board 4 and the Integral air valve chamber cover 5 between monomer cylinder head 1 and the distribution top board 4.
The present invention compared with prior art has following beneficial effect: the present invention is simple in structure; Through increasing the distribution top board structure; Solve monomer-type cylinder head and Integral air valve chamber and covered the sealing of the structure that is complementary; Also solve simultaneously the problem that the distribution device installation precision that adopts the monomer cylinder head to exist is difficult to guarantee, overcome the big shortcoming of design and processes difficulty that piece cylinder head exists again:
(1) adopts the distribution top board structure; Can better realize plane on the distribution top board planeness and with the parallelism of camshaft; Realize the accurate installation and the reliably working of distribution device, the problem that the monomer cylinder head that has solved no distribution top board structure can't guarantee owing to the parallelism of planeness and camshaft that is the upper and lower plane of the single cylinder head that exists of single processing;
(2) through overall peripheral sealing and distribution top board and each the single cylinder sealing of monomer cylinder head of cyclinder head cover and distribution top board, kept the simple advantage of the original sealing configuration of piece cylinder head;
(3) design and optimization difficulty reduce relatively.The monomer-type cylinder head can realize forcing cooling boring, therefore raising cylinder head reliability and the high development of strengthening direction has been stayed very large space;
(4) monomer cylinder head casting technique difficulty reduces, and the corresponding reduction of processing cost is suitable for producing in batches;
(5) versatility, interchangeability are good.
