Description
Technical field
The utility model relates to a kind of engine component, particularly a kind of modular cylinder cover.
Background technique
Cylinder liner is a cylindrical component, and be placed in the cylinder body opening of body, cylinder liner top is fixed by cylinder head.Piston is reciprocating at cylinder cover inner hole, has water quench outside cylinder liner.Along with the development of society, high power engine demand is increasing, and large-diameter and Long travel become necessary, conventional art adopts integral cylinder liner structure, and engine piston easily produces carbon distribution, and particularly piston crown carbon distribution is serious, cause barrel wear, cause engine oil consumption higher.In order to reduce barrel wear, cylinder liner must have certain rotation in the course of the work, to ensure the even wearing of cylinder sleeve, and not eccentric wear.Traditional integral cylinder liner structure cannot meet the demands.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Model utility content
The purpose of this utility model is to provide a kind of modular cylinder cover, thus overcomes existing block-head cylinder cover and cooperatively interact in process with piston, and Piston Carbon is serious, and barrel wear is uneven, the shortcoming that after there is eccentric wear and barrel wear, inconvenience is changed.
For achieving the above object, the utility model provides a kind of modular cylinder cover, and its upper end is provided with cylinder cap, and piston moves reciprocatingly at described cylinder cover inner hole, and described modular cylinder cover comprises: cylinder liner body, and the inwall of its upper end is provided with circular groove; And scrape carbocyclic ring, it is placed on described circular groove, described in scrape carbocyclic ring internal diameter be less than the internal diameter of described cylinder liner body, under the state of piston movement, described in scrape carbocyclic ring and can relatively rotate with described cylinder liner body.
Preferably, in technique scheme, described in scrape carbocyclic ring and described cylinder liner body and be Spielpassung with described cylinder cap.
Preferably, in technique scheme, described in scrape carbocyclic ring internal surface be wear-resistant surface.
Compared with prior art, the utility model has following beneficial effect:
(1) modular cylinder cover of the present utility model, structure is simple, easy to process; Be provided with in the upper end of cylinder liner and scrape carbocyclic ring, can effectively remove piston crown carbon distribution, and scrape carbocyclic ring replacing conveniently.
(2) scrape carbocyclic ring and cylinder liner body and cylinder cap and be Spielpassung, when piston movement, can there is certain vibration in cylinder sleeve, thus make to scrape carbocyclic ring and also certain rotation can occur, ensure that the even abrasion of scraping carbocyclic ring and piston, improve the reliability of engine operation.
Accompanying drawing explanation
Fig. 1 is the structural representation overlapped according to modular cylinder of the present utility model.
Fig. 2 is the partial enlarged drawing according to the utility model I part.
Fig. 3 is the plan view according to scraping carbocyclic ring in the utility model modular cylinder cover.
Fig. 4 is the sectional view according to scraping carbocyclic ring in the utility model modular cylinder cover.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 1 to 4, according to a kind of modular cylinder cover of the utility model embodiment, this modular cylinder cover 1 is located on body 2, and be provided with cylinder cap 3 in cylinder liner 1 upper end, piston 4 moves reciprocatingly at cylinder liner 1 endoporus.
In the middle of present embodiment, this modular cylinder cover 1 comprises: cylinder liner body 11, and the inwall of its upper end is provided with circular groove 12; Scraping carbocyclic ring 13 is positioned on circular groove 12, the internal diameter scraping carbocyclic ring 13 is less than the internal diameter of cylinder liner body 11, scrape carbocyclic ring 13 less than cylinder liner 1 and piston 4 matching gap with piston 4 head fits gap, piston 4 is in cylinder liner 1 during to-and-fro motion, scrape the carbon distribution that carbocyclic ring effectively can strike off piston 4 head, and scrape carbocyclic ring 13 replacing conveniently.Under the state of piston movement, scraping carbocyclic ring 13 can relatively rotate with cylinder liner body 11.
Preferably, scrape carbocyclic ring 13 and cylinder liner body 11 and be Spielpassung with cylinder cap 3, namely scraping between carbocyclic ring 13 and cylinder liner body 11 and there is gap, and also there is gap between cylinder cap 3, when piston movement, can there is certain vibration in cylinder sleeve, makes to scrape carbocyclic ring 13 and also certain rotation can occur.Piston in the course of the work; often there will be the phenomenon of carbon distribution inequality at piston head, scrape the rotation of carbocyclic ring 13, make each piston all different with the point of contact scraping carbocyclic ring; ensure that and scrape carbocyclic ring 13 and the even abrasion of piston 4, improve the reliability of engine operation.
Preferably, the internal surface scraping carbocyclic ring 13 is wear-resistant surface, extends the working life of scraping carbocyclic ring.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
