Abstract
The utility model discloses an engine cylinder cover with a reliable tappet hole support structure, which comprises an engine cylinder cover body. A tappet porous board is arranged on the engine cylinder cover body, tappet holes are arranged on the tappet porous board, a lubricating oil gap is reserved between the tappet porous board and the inner floor of the engine cylinder cover body, and a support rib plate is further arranged between the tappet porous board and the inner floor of the engine cylinder cover body. Since the support rib plate is further arranged between the tappet porous board and the inner floor of the engine cylinder cover body, casting process and machining process of the air cylinder cover are greatly improved and actual running process of an engine is more reliable.
Description
Technical field
The utility model belongs to the vehicle motor component, is specifically related to a kind of engine cylinder cap.
Background technique
The motor of exploitation generally adopts single cylinder four valves, Dual Over Head Camshaft cylinder head both at home and abroad at present, and this type of cylinder head all adopts tappet hole hanging structure, and promptly between the ground 2 lubricant oil gap 3 (as shown in Figure 1) in tappet orifice plate 1 and the cylinder lid; To make things convenient for lubricant oil directly to flow back into engine sump tank from camshaft.The shortcoming of the cylinder head of this class formation is: the path of length just can flow to hanging structure place, tappet hole because liquid metal needs during casting cylinder cover, so the metal compaction degree at hanging structure place, tappet hole is not enough, be easy to generate casting defects such as shrinkage cavity, the intensity at hanging structure place, tappet hole also is affected; Because the bottom of tappet hole structure is unsettled, be easy to generate stress deformation herein when machine adds cylinder head, cause machine to add reject rate and rise, need expend a large amount of man power and materials so machine adds in the process of tappet hole; In the motor practical work process, tappet hole hanging structure is owing to be subjected to periodic lateral forces, easier generation stress deformation.
Summary of the invention
The purpose of this utility model is to provide a kind of engine cylinder cap with reliable tappet hole supporting structure, to address the above problem.
The technical solution of the utility model is: the engine cylinder cap with reliable tappet hole supporting structure, it comprises the cylinder body of getting angry, the cylinder lid is provided with the tappet orifice plate, the tappet orifice plate is provided with the tappet hole, lubricant oil gap between the ground also is provided with bearing rib between the ground in tappet orifice plate and the cylinder lid in tappet orifice plate and the cylinder lid.
Described bearing rib is located in tappet orifice plate between two adjacent tappet holes and the cylinder lid between the ground.
Also be provided with bearing rib between the ground in tappet orifice plate and cylinder lid, the casting technique and the mechanical processing technique of cylinder head all are greatly improved, and the motor actual moving process is also more reliable.
Description of drawings
The engine cylinder cap schematic representation of Fig. 1 existing structure.
Fig. 2 engine cylinder cap schematic representation of the present utility model I.
Fig. 3 engine cylinder cap schematic representation of the present utility model II.
Embodiment
Shown in Fig. 2,3, the tappet orifice plate 4 on the cylinder body 3 of getting angry is provided with tappet hole 5, is being provided with bearing rib 6 between the ground in tappet orifice plate between two adjacent tappet holes 5 and the cylinder lid.In the present embodiment,,, below, per two tappet holes need increase by 8 supporting ribs altogether so increasing the words of a supporting rib owing on the cylinder head 16 tappet holes are arranged.
After having increased by 8 supporting ribs, the casting technique and the mechanical processing technique of cylinder head all are greatly improved, and the motor actual moving process is also more reliable.Can be suitable for novel technological scheme according to this, design the profile and the quantity of supporting rib according to the concrete structure of cylinder head.
Claims (2)
1. engine cylinder cap with reliable tappet hole supporting structure, it comprises the cylinder body of getting angry, the cylinder lid is provided with the tappet orifice plate, the tappet orifice plate is provided with the tappet hole, lubricant oil gap between the ground in tappet orifice plate and the cylinder lid is characterized in that also being provided with bearing rib between the ground in tappet orifice plate and the cylinder lid.
2. the engine cylinder cap that has reliable tappet hole supporting structure according to claim 1 is characterized in that described bearing rib is located in tappet orifice plate between two adjacent tappet holes and the cylinder lid between the ground.
