Problems solved by technology

However, with the development of internal combustion engines, the power density is required to increase, so the explosion pressure of internal combustion engines has been greatly improved. Conventional piston connecting rod materials and structures can no longer meet the requirements of some internal combustion engines. This invention patent is a good solution. The above problems, and bring advantages such as maintenance, reduce the maintenance costs of the factory and users

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0041] figure 1 It is a schematic diagram of an internal combustion engine connecting rod-piston assembly of the present invention. See figure 1 As shown, a connecting rod-piston assembly of an internal combustion engine includes: a piston connecting rod 14, the piston connecting rod 14 has a connecting rod big end and a connecting rod small end, and the connecting rod small end is connected to a piston pin through a matching sleeve. 12;

[0042] A piston with a piston head 6 and a piston skirt 2, the piston pin is respectively connected to the piston skirt 2 and the piston head 6 in sequence through a piston connecting piece;

[0043] The big end of the connecting rod is matched with a large bearing bush.

[0044] Preferably, the piston connector includes an upper pin seat 5, a lower pin se...

Abstract

The invention discloses an internal combustion engine connecting rod piston assembly which comprises a piston connecting rod and a piston. The piston connecting rod is provided with a connecting rod big end and a connecting rod small end, the connecting rod small end is connected with a piston pin in a sleeved mode through matching, the piston is provided with a piston head and a piston skirt, the piston pin is respectively connected with the piston skirt and the piston head in sequence through a piston connecting piece, and the big end of the connecting rod is connected with a big bearing pad in a sleeved mode through matching. The piston is divided into the head portion and the skirt portion to be assembled, and the advantages that the head portion of the piston is taken away directly through piston cooling oil, the heat transmitted to the skirt portion is greatly reduced, thus deformation of the skirt portion is less, and NVH performance of an internal combustion engine is promoted to some extent are achieved.

Description

technical field [0001] The invention relates to the technical field of an internal combustion engine, in particular to a connecting rod piston assembly of an internal combustion engine. Background technique [0002] The piston connecting rod is born with the internal combustion engine, and its function is to withstand the gas pressure in the cylinder and transmit this force to the connecting rod through the piston pin to drive the crankshaft to rotate, thereby converting chemical energy into mechanical energy. However, with the development of internal combustion engines, the power density is required to be higher and higher, so the explosion pressure of internal combustion engines has been greatly improved. Conventional piston connecting rod materials and structures can no longer meet the requirements of some internal combustion engines. This invention patent is a good solution. The above problems are solved, and advantages such as maintenance are brought, and maintenance co...
