Abstract
The utility model discloses a cylinder cover of diesel engine, comprising a body composed of a top wall and an annular side wall, wherein the lower of the body is provided with an opening capable of connecting the cylinder cover, the top wall is provided with a mounting hole, the body is provided with an annular edge bending outwards and upwards, the annular side wall is provided with side wall stiffeners, the top wall is provided with top wall stiffeners connected with the side wall stiffeners, the side wall stiffeners are concave relative to the annular side wall and the top wall stiffeners are convex relative to the top wall. The utility model has highs strength, can prevent oil leakage after the installation on a cylinder cover, and has low production cost and simple structure.
Description
Technical field
The utility model relates to diesel engine part, especially a kind of diesel engine cylinder head cover.
Background technique
Existing diesel engine cylinder head cover, the impact briquetting of general employing iron plate, its opening portion that is connected with cylinder head then adopts double layer construction, the internal layer edge is welded on the ring-like side wall port edge inboard of cover body, has equidistant gap between two-layer, and the internal and external layer mouth is concordant along guaranteeing, and is welded with the inverted U stiffening rib on the cover inwall.This structure diesel engine cylinder head cover, because the very difficult processing in its double-deck edge is concordant, manufacture cost height, and the easy extrusion in double-deck edge cause mouth poorly sealed along portion, are prone to oil leakage phenomenon.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of intensity height, is installed in the diesel engine cylinder housing that is difficult for taking place oil leakage phenomenon on the cylinder head.
For solving the problems of the technologies described above, the utility model comprises the cylinder head cover body that is made of roof and ring-like sidewall, the bottom of described cylinder head cover body is an opening that can be connected with cylinder head, roof is provided with mounting hole, and its structural feature is that described cylinder head cover body mouth is provided with the ring-like edge of outwards upwards turning back along portion.
As to improvement of the present utility model, on ring-like sidewall, be provided with the sidewall reinforcing muscle; On roof, be provided with the roof stiffening rib that links to each other with the sidewall reinforcing muscle; Described sidewall reinforcing muscle is with respect to ring-like concave side wall, and the roof stiffening rib is with respect to the roof evagination.
On roof, be connected with oil inlet pipe, be connected with flow distribution plate on the roof inwall under the oil inlet pipe.
After adopting said structure, because the cylinder head cover mouth has ring-like edge with ring-like sidewall integrative-structure along portion, this ring-like edge docks with cylinder head by U type Stamping Steel Ribbon, its joint good airproof performance, intensity height, can not deform because of fastening cylinder head cover makes its ring-like edge, therefore oil leakage phenomenon can not occur, and processing cost is low.And on ring-like sidewall, be provided with the sidewall reinforcing muscle, and on roof, be provided with the roof stiffening rib that links to each other with the sidewall reinforcing muscle, then further improve the bulk strength of cylinder head cover.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The structural representation that Fig. 1 overlooks for the utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
