Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] The present invention provides an engine connecting rod assembly, comprising connecting rod small end 1, small end bushing 2, rod body 3, connecting rod large end 4, bolt 5 and through hole 6, said connecting rod small end 1 and connecting rod The large rod ends 4 are respectively arranged at both ends of the rod body 3, and the connecting rod small end bushing 2 is pressed into the connecting rod small end 1 with a certain amount of interference. It is determined comprehensively; the shaft 3 is provided with a through hole 6 through the small end 1 of the connecting rod and the large end 4 of the connecting rod. The special-shaped line of the head bushing ensures reliable and sufficient lubrication of the small head of the connecting rod under various working conditions, improves the lubrication and cooling with the piston pin, and reduces the f...

The invention discloses an engine connecting rod assembly. The engine connecting rod assembly comprises a connecting rod small end, a small end lining, a rod body, a connecting rod large end, a bolt and a through hole, the connecting rod small end and the connecting rod large end are arranged at the two ends of the rod body correspondingly, and the connecting rod small end lining is pressed into the connecting rod small end through interference magnitude; and a through hole penetrating through the connecting rod small end and the connecting rod large end is formed in the rod body, and lubricating oil enters the small end lining through the through hole of the rod body to be lubricated and cooled. Through mutual cooperation of the technical scheme, the surface pressure of the connecting rod small end lining is reduced, the pressure distribution and lubrication conditions of the lining are improved, the overall strength of the connecting rod is improved, the requirement for greatly improving the detonation pressure level of an engine is met, and therefore the heat efficiency of the engine is improved, and emission of pollutants is reduced.
Description
technical field [0001] The invention relates to an engine connecting rod assembly suitable for high explosion pressure, which belongs to the technical field of automobile engines. Background technique [0002] The connecting rod assembly connects the piston and the crankshaft, transmits the force acting on the piston to the crankshaft, and converts the reciprocating motion of the piston into the rotational motion of the crankshaft. In order to improve the thermal efficiency of the engine and meet the increasingly stringent emission regulations, the engine needs to continuously increase the explosion pressure. After the explosion pressure is increased, the mechanical load of the connecting rod assembly rises sharply, and its strength needs to be greatly improved. At the same time, the surface pressure of the small-end bushing also increases synchronously, and it is difficult to cope with the increase in surface pressure only by optimizing the bushing material. At present, t...
