Abstract
The invention discloses a skirt structure of an engine cylinder body. The skirt structure comprises cylinder body skirts and pockets, wherein the cylinder body skirts are located at the lower part of the cylinder body and used for being integrally connected with a crankcase; the pockets are formed in crankshaft height positions on the outer sides of the cylinder body skirts and used for reducing the whole weight of an engine. According to the skirt structure of the engine cylinder body, the pockets are formed in the skirts which do not bear working load of the engine or do not have a fastener preload transmitting function and are arranged on the cylinder body, metal materials of the pockets are removed, so that the wall thickness of the cylinder body skirts is partially removed, and the weight of the engine is reduced.
Description
Technical field
The present invention relates to engine art, particularly a kind of skirt structure of engine cylinder.
Background technique
Along with the raising that socio-economic activity requires power performance, Economy, the feature of environmental protection etc., the lightweight of vehicle and component thereof becomes the direction of improvement that obtains extensive concern.
Motor car engine is in the process of work, and need to bear different direction, the load that intensity is different, there is corresponding metallic material at each position therefore in cylinder block to ensure the structural strength of cylinder block.But due to structural reason, in cylinder block, engine workload is not born in some position, the transmission of fastening piece pretightening force is not also affected.The thickness of the metallic material on these positions is excessive, makes the overall weight of cylinder block overweight, does not meet the light-weighted requirement of available engine.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, 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.
Summary of the invention
The object of the present invention is to provide a kind of skirt structure of simple and reasonable engine cylinder, the skirt structure of this engine cylinder arranges lightening grooves by the skirt section of not bearing engine workload or not playing fastening piece pretightening force transmission effect in cylinder block, by removing the metallic material of lightening grooves, the wall thickness of cylinder-block skirt is partially removed, to reach the object reducing engine weight.
For achieving the above object, the invention provides a kind of skirt structure of engine cylinder, the skirt structure of this engine cylinder comprises: cylinder-block skirt, and it is positioned at the bottom of cylinder block, for being connected with crankcase; And lightening grooves, it is opened in the bent axle height and position outside described cylinder-block skirt, for alleviating overall engine weight.
Preferably, in technique scheme, lightening grooves is opened in the both sides of cylinder-block skirt respectively.
Preferably, in technique scheme, the both sides of cylinder-block skirt respectively offer two lightening grooves.
Preferably, in technique scheme, lightening grooves is rectangle.
Compared with prior art, the present invention has following beneficial effect: the skirt structure of this engine cylinder arranges lightening grooves by the skirt section of not bearing engine workload or not playing fastening piece pretightening force transmission effect in cylinder block, by removing the metallic material of lightening grooves, the wall thickness of cylinder-block skirt is partially removed, to reach the object reducing engine weight.
Accompanying drawing explanation
Fig. 1 is the first perspective view of the skirt structure of engine cylinder of the present invention.
Fig. 2 is the second perspective view of the skirt structure of engine cylinder of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention 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 depicted in figs. 1 and 2, comprise according to the concrete structure of the skirt structure of the engine cylinder of the specific embodiment of the invention: cylinder-block skirt 1 and the lightening grooves 2 be opened in outside this cylinder-block skirt.Wherein, cylinder-block skirt 1 is positioned at the bottom of cylinder block, for being connected with crankcase, to install piston, bent axle and other part and accessories.Lightening grooves 2 is opened on cylinder-block skirt 1, and be positioned at the position that cylinder block do not bear engine workload or do not play fastening piece pretightening force transmission effect, by removing the metallic material of lightening grooves, the wall thickness of cylinder-block skirt is partially removed, to reach the object reducing engine weight.
Specifically, cylinder machine is the main body of motor, and each cylinder and crankcase are connected by it, is the support framework installing piston, bent axle and other part and accessories.Be the main body of motor, each cylinder and crankcase are connected by it, are the support frameworks installing piston, bent axle and other part and accessories.The operating conditions of cylinder block is very severe.It will bear the strong friction of sharply change and the piston movement of pressure and temperature in combustion process.
Cylinder-block skirt 1 is positioned at the bottom of cylinder block, for being connected with crankcase, to install piston, bent axle and other part and accessories.
Lightening grooves 2 is opened on cylinder-block skirt 1, and be positioned at (the cylinder block bottom, position of cylinder block not bearing engine workload or not playing fastening piece pretightening force transmission effect, the place roughly the same with bent axle height and position), by removing metallic material, overall engine weight can be alleviated.Not being on cylinder bolt pretightening force route due to this position and can not affecting the intensity of cylinder block, therefore removing metallic material can not have an impact to the sealing of motor or bulk strength.Preferably, lightening grooves 2 is opened in the both sides of cylinder-block skirt 1 respectively, and the both sides of cylinder-block skirt 1 offer two lightening grooves 2 respectively.Preferably, lightening grooves 2 is rectangle.
Also can adopt and offer weight reduction openings in the skirt section of engine cylinder, but owing to there is a large amount of gas mixtures in crankcase, can not directly emit from cylinder block opening, therefore after cylinder-block skirt empties removal metallic material, need with thinner material, weight reduction openings place to be covered, in order to avoid the gas mixture in crankcase is revealed.This motion, by engine cylinder skirt, compared with Current protocols (without falling the cylinder block reopening mouth), has the advantage that weight is low, the cost of material is low.
To sum up, the skirt structure of this engine cylinder arranges lightening grooves by the skirt section of not bearing engine workload or not playing fastening piece pretightening force transmission effect in cylinder block, by removing the metallic material of lightening grooves, the wall thickness of cylinder-block skirt is partially removed, to reach the object reducing engine weight.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention 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 invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
