Further, described groove is U-shaped groove.
Further, the width of described U-shaped groove is 1/3rd of described piston ring thickness, described projection
Obtaining thickness is 1/3rd of described piston ring thickness.
The invention has the beneficial effects as follows: piston is by the positioning component on piston seat and the location on piston pin
Hole, it is achieved the location of piston pin and piston boss is fixed, it is to avoid piston pin occurs phase during using
To slip.Two or more holes, location and together with the setting of positioning component that matches so that position
Effect is better.The two ends of piston ring are respectively provided with U-shaped groove and the projection with groove match, keep away
Exempt from piston ring to be arranged in described piston groove and there is opened gap passage on back piston ring, described U-shaped recessed
The width of groove is 1/3rd of described piston ring thickness, and it is described annular thickness that described projection obtains thickness
The setting of 1/3rd can guarantee that the intensity at piston ring two ends.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of piston of automobile of the present invention, and in accompanying drawing, top land does not cuts open, other
Part is sectional view；
In accompanying drawing, the list of parts representated by each label is as follows:
