Abstract

The utility model provides a novel aluminium piston abrasion resistant inlay circle which belongs to a novel abrasion resistant inlay circle for manufacturing the aluminium piston and comprises an inlay circle body, the inner side of the inlay circle body is provided with a cold channel ring, and the inner surface of the inlay circle body is provided with a heat radiating groove. Because the abrasion resistant inlay circle has the heat-radiating groove, thus increasing the heat absorption area of the cooling oil during the process of using the piston, improving the cooling effect, reducing the temperature of the piston head portion, relatively improving the piston strength, simultaneously because the temperature of a first groove is greatly reduced, the adhesion of the piston ring groove and the piston ring friction can be effectively prevented, thereby not only leading the high load engine piston first gaseous ring to be able to adopt the cheap rectangular ring, but also improving the working condition of each gaseous ring and oil ring, reducing the consumption of oil, and improving the using performance and the service life of the piston.

Description

A kind of novel aluminum piston abrasion-proof inserted ring

Technical field

The utility model provides a kind of novel wear resistant edge circle that the aluminium piston is made that is used for.

Background technique

Piston is the critical component of motor.Along with the development of motor to high-power, low oil consumption, low noise and low emission, traditional single all-aluminium piston is difficult to meet the demands, and piston first groove wear is fast, causes gas blowby, pull-cylinder phenomena, influences the usability and the life-span of piston.At the head castingin abrasion-proof inserted ring of piston, can play the effect that improves the first annular groove wear resistance and piston ring groove-piston ring friction pair functional reliability.A kind of abrasion-proof inserted ring with the inner cooling path ring is arranged now, be cast into piston after, can form inner cooling path at piston crown.Cold oil is flowed in this passage, play the effect that reduces the piston crown temperature.But the side near abrasion-proof inserted ring in this inner cooling path ring inner surface is a simple toroidal surface, and heat diffusion area is little, and cooling effect is relatively poor.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of novel aluminum piston abrasion-proof inserted ring, to enlarge the heat diffusion area of inner cooling path, the raising cooling effect.

The utility model is achieved in that the piston abrasion-proof inserted figure of a kind of novel aluminum, and it has the edge circle body, and there is the inner cooling path ring edge circle body inboard, at described edge circle body internal surface the heat radiation groove is arranged.

Adopt the abrasion-proof inserted ring of said structure, because the existence of heat radiation groove is arranged, enlarged the heat absorption area of cold oil in the piston using process, thereby improved cooling effect, reduced the temperature of piston crown, improved piston intensity relatively, temperature owing to first annular groove reduces significantly simultaneously, can effectively prevent the adhesion of piston ring groove-piston ring friction pair, not only make high load engine piston top compression ring can adopt low-cost rectangular ring, but also improved each compression ring, the operating conditions of oil ring, thus consumption of lubricating oil reduced, improved the usability and the working life of piston.

Embodiment

The embodiment who provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.

As shown in drawings, a kind of novel aluminum piston abrasion-proof inserted ring of the utility model, it has edge circle body 1, and there is inner cooling path ring 3 edge circle body inboard, at described edge circle body 1 internal surface heat radiation groove 2 is arranged.

The cross section of inner cooling path ring is c-shaped, and the internal surface of edge circle body is the part of inner cooling path ring inner chamber.The internal surface of edge circle body is exactly the face that is positioned at the inner cooling path ring.That the part that the cross section of inner cooling path ring could also be designed to and inlay circle body constitutes is circular, oval, rectangle and multiple shape such as trapezoidal.

The heat radiation degree of depth of groove and width are principle with the intensity that not only helps dispelling the heat but also do not influence abrasion-proof inserted ring.The sectional shape of heat radiation groove can be rectangle, trapezoidal, semicircle, V-arrangement, perhaps is two or more combination in the above-mentioned shape.The distribution of heat radiation groove can be as Fig. 1-horizontal distribution shown in Figure 6, vertical distribution as shown in Figure 7, as shown in Figure 8 tilt distribution.So-called level, vertical or tilt to be meant that the heat radiation groove is for the upper and lower plane of abrasion-proof inserted ring.

Described heat radiation groove 2 is horizontal distribution, and the quantity of heat radiation groove 2 has more than 1 or 1.The most frequently used is 1 or 2.A groove can increase inner cooling path inner chamber heat diffusion area more than 6%.

Described heat radiation groove 2 is vertical or tilt distribution, and the quantity of heat radiation groove 2 has a plurality of.It can make inner cooling path inner chamber heat diffusion area increase more than 8%.

Described edge circle body 1 is fixed by welding in inner cooling path ring 3.

Described edge circle body 1 is cast as one simultaneously with heat radiation groove 2.After finishing, casting can carry out cutting again.

Edge circle body outer surface can be cylndrical surface as shown in Figure 1 and Figure 4, also can be as Fig. 2 and shown in Figure 5 have the cylndrical surface of dome ring 4, can also be as Fig. 3 and shown in Figure 6 the cylndrical surface of concave ring groove 5 is arranged.Dome ring and concave ring groove can be not yet in the centre of edge circle body but deflection near its a certain side, the sectional shape of dome ring or concave ring groove can be rectangle, trapezoidal, semicircle, V-arrangement, perhaps is two or more combination in the above-mentioned shape.

As Fig. 9, shown in Figure 10, during use, the abrasion-proof inserted ring of the utility model is positioned at the head of aluminium piston, the edge circle body constitutes first annular groove of piston, or first and second annular groove, its internal surface and inner cooling path ring inner surface constitute inner cooling path, and the heat radiation groove of edge circle body internal surface has effectively increased the surface area of inner cooling path inner chamber, thereby has enlarged heat diffusion area.

As shown in figure 11, on existing abrasion-proof inserted ring, the side near abrasion-proof inserted ring in the inner cooling path ring inner surface is a simple toroidal surface, compares with the utility model, and heat diffusion area is little.
