Embodiment Construction
[0045] The piston of the crank-slider mechanism of the single-cylinder engine of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0046] figure 1 The front view of the piston of the slider crank mechanism provided by the embodiment of the present invention. in, figure 1Shown is a single-acting piston, i.e. fitted with a piston skirt and crown at only one end of the piston seat, it should be understood that the piston of the present invention may also be a double-acting piston, i.e. at the other end of the piston seat A skirt and a top are also installed at the same time. This embodiment only uses one end of the piston seat to be equipped with the piston skirt and the top as an example to illustrate the piston of the crank and slider mechanism of the present invention, and the other end of the piston seat can also be installed in the same or similar manner as the embodiment of the present invention ...

The invention discloses a piston of a circular slider-crank mechanism, comprising top, skirt and a piston seat, wherein, the skirt comprises an installation seat and an extension part extending along the profile of the installation seat; a circular slider containing hole is arranged on the piston seat; the top is fixedly assembled on an end face which is positioned on the installation seat and isopposite to the extension direction of the extension part; one end of the piston seat is fixedly assembled on an end face which is positioned on the installation seat and is opposite to the end face on which the top is installed. Locating viaholes are arranged on the installation seat and locating blind holes are arranged in the corresponding positions of the top and the piston seat. The locatingblind holes on the piston seat and at the top are respectively communicated with oil supply channels on the piston seat and at the top. During assembling, hollow locating pins pass through the locating viaholes and are respectively inserted into the locating blind holes at the top and on the piston seat. The oil supply channels at the top of the piston and on the piston seat are communicated. Thepiston of the invention can realize working under lubricating oil pressure and cooling of the top of the piston. The invention also provides an internal combustion engine.
Description
technical field [0001] The invention relates to a piston, in particular to a piston of a crank circular slider mechanism. The invention also relates to an internal combustion engine with a crank circular slider mechanism. Background technique [0002] In a traditional internal combustion engine, the reciprocating motion of the piston is converted into the rotational motion of the crankshaft through the crank connecting rod structure, and then the crankshaft drives the corresponding moving parts to output power externally. However, in the crank-link mechanism, due to the existence of the connecting rod, the internal combustion engine of the crank-link mechanism has defects such as bulky, heavy, and poor balance performance. [0003] In order to solve the above problems, the Chinese patent with the date of examination and approval announcement as January 13, 1988 and the announcement number as CN85200358B discloses a "crank circular slider reciprocating piston internal combus...
