Abstract
The utility model discloses a piston with a steel top and an aluminium skirt, comprising a piston top and a piston skirt, wherein the piston top and the piston skirt are connected via a stud and a pin; and a spring bayonet lock is disposed on the stud. At present, a high-strength and low-temperature-expansion material is used on the piston with a steel top and an aluminium skirt disclosed by the utility model having such structure type, and the type of piston structures have different cylinder diameters ranging from 160 to 400 mm currently; the piston can replace a combined piston, so that the cost is lower; moreover, the piston can continuously work in bad working conditions of heavy oil burning, high detonation pressure etc.
Description
Technical field
The utility model relates to a kind of steel crown and aluminum skirt piston.
Background technique
In the existing technology, steel crown and aluminum skirt piston is provided with a plurality of nuts, bolt arrangement, causes this kind piston structure complicacy, and cost is higher.
Summary of the invention
The purpose of the utility model provides a kind of steel crown and aluminum skirt piston.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of piston head and piston skirt of comprising, be connected with pin through double-screw bolt between said piston head and the piston skirt, and said double-screw bolt is provided with spring detent.
Said double-screw bolt is fixedly connected piston head and piston skirt through nut.
Be provided with elastic sleeve between the top of said double-screw bolt and piston skirt.
Be provided with the O RunddichtringO between said piston head and the piston skirt.
A kind of steel crown and aluminum skirt piston of the utility model; The material that present high tenacity, low temperature expand has been used for this structural type piston; At present this type of piston structure does not wait from the 160-400mm cylinder diameter, and this kind piston can the alternative combinations piston, makes cost more cheap; And can be under abominable operating mode such as burning heavy oil, high detonation pressure, continual work.
