Abstract
The utility model relates to a kind of diesel engine cylinder head cover.Include cover body (1), ripple side plate (2), perforation boss (3), sealing stiffening rib (4), connect table top (5), fill with steel wire lump (6) in perforation boss (3) and around outlet pipe (7), connect on table top (5) and be provided with circle sealing stiffening rib (4).The utility model diesel engine cylinder head cover, the side plate of cover body adopts corrugated form, energy absorbing vibrational energy and increasing heat radiation area, therefore the effect that can realize noise reduction heat radiation; The sealing stiffening rib connected on table top withstands on the sealing gasket in cylinder head, strengthens sealing effect; Fill with steel wire lump around outlet pipe, can effectively stop that mist of oil is excessive.
Description
Technical field
The utility model relates to the part field of diesel engine, particularly 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 be connected with cylinder head then adopts double layer construction, internal layer edge is welded on inside the annular sidewall opening's edge of cover body, before two-layer, there is equidistant gap, and internal and external layer is along smooth, and cover inwall is welded with inverted U stiffening rib.This structure diesel engine housing, because the very difficult processing in its double-deck edge is concordant, manufacture cost is high, and the extrusion of double-deck edge, cause opening's edge portion poorly sealed, easily occur oil leakage phenomenon.
Summary of the invention
The purpose of this utility model be to provide a kind of can noise reduction heat radiation, tightness is good, be arranged on the diesel engine cylinder head cover that cylinder head not easily occurs oil leakage phenomenon.
For solving the problems of the technologies described above, the utility model cylinder head cover of diesel engine, comprises cover body 1, and the biside plate of described cover body 1 is ripple side plate 2, in the perforation boss 3 at described cover body 1 top, be filled with steel wire lump 6, the connection table top 5 at described cover body 1 opening end edge have sealing stiffening rib 4.Sealing stiffening rib 4 on described connection table top 5 has a circle or two circle distributions.
The beneficial effects of the utility model: the utility model side plate adopts the form of ripple, realizes the effect of noise reduction, simultaneously corrugated sheet energy absorbing vibration energy, therefore the effect of noise reduction heat radiation can be realized; The sealing stiffening rib connected on table top withstands on the sealing gasket in cylinder head, strengthens sealing effect; Fill with steel wire lump around outlet pipe, can effectively prevent from stopping that mist of oil is excessive.
Accompanying drawing explanation
Fig. 1 is the utility model structure plan view
Fig. 2 is the utility model A-A sectional view
Drawing reference numeral illustrates: 1. cover body, 2. ripple side plate, and boss of 3. boring a hole, 4. seals stiffening rib, 5, connect table top, 6, steel wire lump, 7, outlet pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
Embodiment: as shown in Figure 1, the utility model diesel engine cylinder head cover, the biside plate 2 of cover body 1 adopts the side plate of corrugated form, contributes to the surface radiating area increasing diesel engine cylinder head cover, reaches the effect strengthening heat radiation; Ripple side plate 2 adopts the form of ripple simultaneously, contributes to absorption of noise, reaches the effect of noise reduction.
As shown in Figure 2, the utility model diesel engine cylinder head cover, the connection table top 5 at cover body 1 opening end edge is provided with 1 circle or 2 circle sealing stiffening ribs 4, when installing seal ring, sealing stiffening rib 4 withstands on the seal ring of cylinder head, enhances the sealability of cylinder head.As shown in Figure 2, the utility model the utility model diesel engine cylinder head cover, is filled with steel wire lump 6 in the perforation boss 3 at cover body 1 top, and outlet pipe 7 is through perforation boss 3, fill with steel wire lump 6, for stopping that mist of oil is excessive around outlet pipe 7 and in perforation boss 3.
Claims (2)
1. a diesel engine cylinder head cover, comprise cover body (1), it is characterized in that the biside plate of described cover body (1) is ripple side plate (2), in the perforation boss (3) at described cover body (1) top, be filled with steel wire lump (6), the connection table top (5) at described cover body (1) opening end edge has sealing stiffening rib (4).
2. diesel engine cylinder head cover according to claim 1, is characterized in that the sealing stiffening rib (4) on described connection table top (5) has a circle or two circle distributions.
