Abstract
The utility model discloses a special cylinder liner for an automobile engine. The special cylinder liner comprises a body (5) with six combustion holes (1) alternatively arranged along the length direction, wherein a tappet hole (3) is formed in the center of the body (5), threaded holes (6) are formed in the body (5) and positioned in peripheries of the combustion holes, a metal member (2) is arranged on the inner ring of each combustion hole (1), and the thickness of the metal members (2) is more than that of the body (5). Through using the special cylinder liner for the automobile engine, the service life of a cylinder body can be effectively prolonged, and the sealing property between the cylinder body and a cylinder cover is increased; and meanwhile, the special cylinder liner also has the characteristics of simple structure, convenience in use and installation, and the like, and is suitable for popularization and use.
Description
Technical field
The utility model relates to a kind of motor car engine component, is specifically related to a kind of motor car engine specialized gas cylinders pad.
Background technique
Cylinder liner is one of component in the piston compressor, cylinder liner plays a part very important in automobile is used, the effect of cylinder liner is the gap between sealed cylinder block and the valve plate, cylinder liner lost efficacy cause easily oozing, emit, drip, phenomenon such as leakage, the serious performance that then has influence on whole part or even cause serious security incident, but existing cylinder liner major part is a rubber seal, can't satisfy the requirement of user's countercylinder pad, use very inconvenient, the working life of reducing cylinder body.
The model utility content

The technical problems to be solved in the utility model provides a kind of exhaust and convenient, and is simple in structure, reasonable in design, good seal performance, the motor car engine specialized gas cylinders pad of safety durable.
(2) technological scheme
For addressing the above problem, the utility model adopts following technological scheme:
A kind of motor car engine specialized gas cylinders pad, comprise that one has the body (5) of 6 spaced along its length burning holes (1), described body (5) central position is provided with tappet bore (3), the place, border that is positioned at described burning hole (1) on the described body (5) is provided with tapped hole (6), the inner ring of described burning hole (1) is provided with metalwork (2), and the thickness of described metalwork (2) is greater than described body (5).
The upper and lower surface of described body (5) is respectively equipped with scuff-resistant coating (7).
The lower edge that is positioned at each described burning hole (1) on the described body (5) is provided with positioning hole (4).
(3) beneficial effect
The beneficial effects of the utility model are: by using motor car engine specialized gas cylinders pad of the present utility model, can effectively improve the working life of cylinder body, increase the sealing between cylinder body and the cylinder cap, and the utility model also has simple in structure, characteristics such as easy to install and use are fit to promote the use of.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model motor car engine specialized gas cylinders pad.
Fig. 2 is the structural representation in the utility model motor car engine specialized gas cylinders pad A-A cross section.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, a kind of motor car engine specialized gas cylinders pad, comprise that one has the body 5 of 6 spaced along its length burning holes 1, described body 5 central positions are provided with tappet bore 3, the place, border that is positioned at described burning hole 1 on the described body 5 is provided with tapped hole 6, the inner ring of described burning hole 1 is provided with metalwork 2, and the thickness of described metalwork 2 is greater than described body 5.The metalwork inner ring diameter is identical with engine cylinder combustion chamber diameter, replaces integrated burning hole with metalwork, can improve the cylinder liner whole service life.
The upper and lower surface of described body 5 is respectively equipped with scuff-resistant coating 7.Scuff-resistant coating is set further working life of improving cylinder liner.
The lower edge that is positioned at each described burning hole 1 on the described body 5 is provided with positioning hole 4.During installation, position with positioning hole 4 countercylinder pads earlier, the screw of packing in tapped hole 6 again carries out fastening.
By using motor car engine specialized gas cylinders pad of the present utility model, increase the sealing between cylinder body and the cylinder cap working life that can effectively improve cylinder body, and the utility model also has characteristics such as simple in structure, easy to install and use, be fit to promote the use of.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
