Abstract
The utility model relates to a kind of engine aluminum alloy valve tappet, belongs to the distribution device technical field of motor car engine.Draw together cylindrical stack shell, described cylindrical stack shell interior bottom portion center is provided with for the boss with valve contacts, is connected with radial equally distributed stiffening rib between inside described boss outer and cylindrical stack shell.The utility model is to valve tappet working strength and the good aluminum alloy material of wear resistance, its weight can be reduced greatly, simultaneously in order to meet the rigidity requirement of aluminum alloy valve tappet, devising reinforcing rib structure in the top inner side of valve tappet, improving the rigidity of its end face; This project organization is convenient to processing in addition, can not affect the layout of engine valve actuating mechanism.
Description
Technical field
The utility model belongs to the distribution device technical field of motor car engine, is specifically related to a kind of engine aluminum alloy valve tappet.
Background technique
Existing valve tappet, its material is often all alloyed steel, and quality is larger.Because valve tappet is the major part driving valve in engine valve actuating mechanism, its quality size can affect the dynamic performance of distribution device, also can affect the size of valve spring force simultaneously.If valve spring force is comparatively large, then the frictional work of distribution device will increase, and engine consumption will increase.The weight alleviating the tappet of valve can effectively make valve spring force reduce, and so just can reduce distribution device frictional work, reduces the oil consumption of motor.
Model utility content
The purpose of this utility model is exactly the defect for prior art, provides a kind of engine aluminum alloy valve tappet.Reduce the weight of valve tappet, thus can valve spring force be reduced, reduce the frictional work of engine valve actuating mechanism, reach the object reducing engine consumption.
The technical solution adopted in the utility model is: comprise cylindrical stack shell, and described cylindrical stack shell interior bottom portion center is provided with for the boss with valve contacts, is connected with radial equally distributed stiffening rib between inside described boss outer and cylindrical stack shell.
Further, described stiffening rib number is four to eight.
Further, the material of described cylindrical stack shell is aluminum alloy.
The utility model is to valve tappet working strength and the good aluminum alloy material of wear resistance, its weight can be reduced greatly, simultaneously in order to meet the rigidity requirement of aluminum alloy valve tappet, devising reinforcing rib structure in the top inner side of valve tappet, improving the rigidity of its end face; This project organization is convenient to processing in addition, can not affect the layout of engine valve actuating mechanism.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model internal structure schematic diagram;
Fig. 3 is the utility model sectional view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As shown in Fig. 1-Fig. 3, the utility model comprises cylindrical stack shell 1, and described cylindrical stack shell 1 interior bottom portion center is provided with for the boss 3 with valve contacts, is connected with radial equally distributed stiffening rib 2 between inside described boss 3 outer and cylindrical stack shell 1.Described stiffening rib 2 number is four to eight.The material of described cylindrical stack shell 1 is aluminum alloy.
Valve tappet structure available dedicated mould described in the utility model is extruded, because reinforcing rib structure is not surface of contact, can not reprocess after general mould is extruded; Central boss due to valve contacts, also tackle it after mould is extruded and carry out machine and add process, to ensure precision.Premised on the rigidity meeting valve tappet, reinforcing rib structure can choose reasonable.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
Claims (3)
