Abstract
An automobile engine piston is disclosed and the automobile engine piston relates to the automobile engine filed. The automobile engine piston comprises an oval barrel-shaped piston body (1) and a fire bank (2), wherein a first compression ring (3), a second compression ring (4) and an oil ring are arranged on the fire bank (2), and a reinforcing rib (6) is arranged on the pin seat (7) of the oval barrel-shaped piston body (1). The automobile engine piston is characterized by reasonable structure design, reliable performance, high heat intensity, and ease of popularization and use.
Description
Technical field:
The utility model relates to the motor car engine field, is specifically related to a kind of piston of automobile engine.
Background technique:
Present petrolic piston all is aluminum alloy, but because the linear expansion rate of aluminum alloy is higher, guiding and the gap temperature influence between piston and cylinder to the piston skirt are larger, so control the expansion in skirt section, simultaneously because the requirement of discharging, the height of the requirement of firepower bank is being satisfied try one's best under the prerequisite of intensity little.Under equiponderant prerequisite, require the cross section of piston large as much as possible, require simultaneously the frictional work of piston low as much as possible.
The model utility content:
The purpose of this utility model provides a kind of piston of automobile engine, and it can reduce the cold clearance of motor, effectively reduces the discharging of hydrocarbon, increases the main heat transfer sectional area of piston, reduces thermal distortion and the heat load of piston.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises oval bucket piston body 1 and firepower bank 2; Be provided with first gas ring 3, second gas ring 4, the 3rd compression ring 5, the 4th compression ring 6, the first oil ring 7 and the second oil ring 8 on the firepower bank 2, be provided with stiffening rib 9 on the key seat 10 of oval bucket piston body 1.
Described firepower bank 2 adopts three ring bank structures, and whole is taper.
The utility model adopts oval barrel-shaped design, effectively controls the expansion in skirt section; Adopt three ring bank designs, adopt simultaneously low firepower bank design and unitary tapered design, reduced the cold clearance of motor, effectively reduce the discharging of hydrocarbon.Key seat at piston only adopts reinforcing rib design, has effectively increased the main heat transfer sectional area of piston, reduces thermal distortion and the heat load of piston, has reasonable in design, reliable performance, and the characteristics that hot strength is high are easy to promote and use.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is that A-A of Fig. 1 is to sectional view.
Embodiment:
With reference to Fig. 1, Fig. 2, this embodiment by the following technical solutions: it comprises oval bucket piston body 1 and firepower bank 2; Be provided with first gas ring 3, second gas ring 4, the 3rd compression ring 5, the 4th compression ring 6, the first oil ring 7 and the second oil ring 8 on the firepower bank 2, be provided with stiffening rib 9 on the key seat 10 of oval bucket piston body 1.
Described firepower bank 2 adopts three ring bank structures, and whole is taper.
This embodiment adopts oval barrel-shaped design, effectively controls the expansion in skirt section; Adopt three ring bank designs, adopt simultaneously low firepower bank design and unitary tapered design, reduced the cold clearance of motor, effectively reduce the discharging of hydrocarbon.Key seat at piston only adopts reinforcing rib design, has effectively increased the main heat transfer sectional area of piston, reduces thermal distortion and the heat load of piston, has reasonable in design, reliable performance, and the characteristics that hot strength is high are easy to promote and use.
Claims (2)
