Abstract

The utility model relates to a combined type of cylinder liner of the combustion engine. A thin-wall alloy lined is enchased on the inner surface of the cylinder body, a shallow ring flute is arranged on one side of the inner surface of the cylinder body referred and faces to the inner boring, a ring thin-wall alloy lined is embedded and fixed tight in the shallow ring flute located on the inner face of the cylinder body. Due to the design above, the cylinder body has a simple structure, long operating life and dramatically reducing on the cost of maintenance and using, in addition other advantages can be obtained such as long-term and strong power of the engine, the decreasing cost of fuel, the reduced discharge of harmful gas in the off-gas and the favor of the environment.

Description

Internal-combustion engine combined type cylinder liner

Technical field

The utility model relates to a kind of cylinder liner of explosive motor, especially a kind of common wet liner belongs to the parts of motor.

Background technique

In the prior art, the cylinder liner of various motors is integral structure component, the cylinder sleeve body that is cylinder liner is that same metal body is made, and wet liner particularly is because its wall body is very abundant, in production and processing cylinder body process, owing to outside water-cooled and inner reason such as natural air cooled, i.e. the mode difference of cylinder sleeve inside and outside metal heat treatmet makes that the metal hardness of internal surface and abrasion resistance are all much lower than outer surface, cause " outer just interior gentle ", influence the working life of entire cylinder body.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of, can significantly improve the internal-combustion engine combined type cylinder liner in working life, and it is at the internal surface of the cylinder sleeve body thin wall alloy inner lining body of having spliced.

Be shaped on shallow ring recess from the inside boring of an end face on the internal surface of described cylinder sleeve body, the thin wall alloy inner lining body interlocking of a round is also fastening in the shallow ring recess of cylinder sleeve body internal surface.

The utility model compared with prior art; have simple in structure; long service life; with common 6110 diesel engines is example, and be increased to three, four ten ten thousand kilometer from former more than 10 ten thousand kilometers engine cylinder body working life of its use, and the cost of safeguarding, using reduces greatly; can keep the long-term powerful power of motor; save fuel cost, reduce the discharge of harmful gases of tail gas, help protecting characteristics such as environment.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: the utility model mainly includes the cylinder sleeve body 1 of a cylinder liner, the internal surface of this cylinder sleeve body 1 begins to make a shallow ring recess 2 with the boring of Vehicle Processing form from one end, the thin wall alloy inner lining body 3 of one tubular embeds and is inserted at the end from this open end, and be fixed in the shallow ring recess by interference fit, reaching the alloy lining body splices in the purpose of cylinder sleeve body internal surface, because it is hard that thin wall alloy inner lining body 3 has intensity, characteristic such as wear-resisting, thereby can prolong its working life, even inner lining body has worn and torn, also as long as change this inner lining body easily, can utilize original cylinder sleeve body easily equally, reached the economical with materials cost, reduced and use, purposes such as maintenance expenses.

Claims

1, a kind of internal-combustion engine combined type cylinder liner is characterized in that it is at the internal surface of cylinder sleeve body (1) the thin wall alloy inner lining body (3) of having spliced.

2, internal-combustion engine combined type cylinder liner according to claim 1, it is characterized in that being shaped on shallow ring recess (2) from the inside boring of an end face on the internal surface of described cylinder sleeve body (1), thin wall alloy inner lining body (3) interlocking of a round is also fastening the shallow ring recess (2) of cylinder sleeve body internal surface in.
