Abstract
The utility model discloses an aluminum alloy air cylinder cover cap for an internal-combustion engine, which belongs to the technical field of an internal-combustion engine component and mainly comprises an air cylinder cover cap body, wherein a cap cavity is arranged on the air cylinder cover cap body, and two position limiting parts used for limiting a rocker arm of the internal-combustion engine are arranged on the air cylinder cap cover body and are symmetrically arranged at the inner side of the cap cavity wall. The aluminum alloy air cylinder cover cap for the internal-combustion engine has the advantages that the weight is light, the intensity requirement can be met, the rocker arm can be limited, the noise is reduced, and the aluminum alloy air cylinder cover cap is widely applied to the manufacture and the use of the internal-combustion engine.
Description
Technical field
The utility model relates to the gas engine part technical field, relates in particular to a kind of aluminium alloy cylinder housing that is used for internal-combustion engine.
Background technique
Valve mechanism cover is one of common component of internal-combustion engine, and it mainly acts on is to prevent that the machine oil in the valve mechanism cover from leaking outside, and in the design process of valve mechanism cover, should pay special attention to the intensity and the sealability of valve mechanism cover.At present, valve mechanism cover adopts the cast steel casting usually in order to reach enough intensity, and in use, owing to the frictional impact of rocking arm and valve mechanism cover produces the noise of comparison, thereby influences the whole usability of internal-combustion engine.
The model utility content
Technical problem to be solved in the utility model is: a kind of aluminium alloy cylinder housing that is used for internal-combustion engine is provided, and in light weight, can either satisfy requirement of strength, can retrain rocking arm again, reduce noise.
For solving the problems of the technologies described above, the technical solution of the utility model is: the aluminium alloy cylinder housing that is used for internal-combustion engine, comprise the valve mechanism cover body, has a cover chamber on the described valve mechanism cover body, described valve mechanism cover body is provided with two limited parts that are used to retrain the internal-combustion engine rocking arm, and described two limited parts are symmetricly set in the inboard of described cover chamber wall.
As a kind of improvement, be respectively equipped with a mounting hole that is used for fixing described valve mechanism cover body on the valve mechanism cover body of both sides, described cover chamber.
After having adopted technique scheme, the beneficial effects of the utility model are: adopt the aluminum alloy material casting when making owing to valve mechanism cover, guaranteed the needed requirement of strength of valve mechanism cover, can produce in batches, reduce production costs, alleviate the weight of whole internal-combustion engine simultaneously, reduced kinetic equation loss; Again because the valve mechanism cover body is provided with two limited parts that are used to retrain the internal-combustion engine rocking arm, during use, the rocking arm constraint is installed between two limited parts, has reduced the frictional impact of rocking arm and valve mechanism cover, thereby reduced mechanicalness noise, improved the usability of internal-combustion engine.
Because the valve mechanism cover body is provided with mounting hole, mounting hole site is in cover both sides, chamber, and is stressed even when making the installation of valve mechanism cover body, installs firmly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the sectional view of A-A among Fig. 1;
Among the figure: 1, valve mechanism cover body, 11, limited part, 12, mounting hole, 2, the cover chamber.
Embodiment
As depicted in figs. 1 and 2, a kind of aluminium alloy cylinder housing that is used for internal-combustion engine, mainly comprise valve mechanism cover body 1, has a cover chamber 2 on the described valve mechanism cover body 1, described valve mechanism cover body 1 is provided with two limited parts 11 that are used to retrain the internal-combustion engine rocking arm, described two limited parts 11 are symmetricly set in the inboard of described cover chamber wall, from moulding, the sectional shape such as the same buttferfly-type in cover chamber 2, both beautiful and practical, the rocking arm constraint is installed between two limited parts 11, has reduced the frictional impact of rocking arm and valve mechanism cover, thereby reduced mechanicalness noise, improved the usability of internal-combustion engine.Be respectively equipped with a mounting hole 12 that is used for fixing described valve mechanism cover body 1 on the valve mechanism cover body 1 of 2 both sides, described cover chamber, during installation, the connecting bolt symmetric arrangement, valve mechanism cover body 1 is stressed even, is connected firmly with the internal-combustion engine housing.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
Claims (2)
1. the aluminium alloy cylinder housing that is used for internal-combustion engine, comprise the valve mechanism cover body, has a cover chamber on the described valve mechanism cover body, it is characterized in that: described valve mechanism cover body is provided with two limited parts that are used to retrain the internal-combustion engine rocking arm, and described two limited parts are symmetricly set in the inboard of described cover chamber wall.
2. the aluminium alloy cylinder housing that is used for internal-combustion engine as claimed in claim 1 is characterized in that: be respectively equipped with a mounting hole that is used for fixing described valve mechanism cover body on the valve mechanism cover body of both sides, described cover chamber.
