Problems solved by technology

When the big ends of the two connecting rods are stacked together, the gap between the contact surfaces is very small, causing the big head hole of the connecting rod to form a dead zone for one-way flow, which hinders the forward flow of lubricating oil, resulting in the big hole of the connecting rod, the connecting rod The lubricating oil film between the bearing bushes is damaged due to overheating, and at the same time, the heat of the connecting rod bearing bushes is accumulated and burned

Abstract

The invention discloses a connecting rod big end structure applied to a V-type diesel engine. The connecting rod big end structure comprises a first connecting rod big end and a second connecting rod big end which are overlapped. The first connecting rod big end is provided with a first big end hole, the second connecting rod big end is provided with a second big end hole, and the attached end face of the first connecting rod big end and / or the second connecting rod big end is provided with an oil groove. The connecting rod big end structure improves lubrication performance of the V-type diesel engine, heat of the connecting rod big ends and a connecting rod bearing shell is fully dissipated, oil films which move relative to the position of the big end holes are guaranteed, the problem that the connecting rod bearing shell is damaged due to overheating is also solved, and reliability of the engine can be guaranteed.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a connecting rod big end structure applied to a V-type diesel engine. Background technique [0002] At present, the large end of the connecting rod of the V-type diesel engine is not much different from the conventional in-line connecting rod, and two conventional connecting rods are often used to stack the crank pin of the same gear. When the big ends of the two connecting rods are stacked together, the gap between the contact surfaces is very small, causing the big head hole of the connecting rod to form a dead zone for one-way flow, which hinders the forward flow of lubricating oil, resulting in the big hole of the connecting rod, the connecting rod The lubricating oil film between the bearing pads will be damaged due to overheating, and at the same time, the heat of the connecting rod bearing pads will accumulate and burn out. [0003] The information disclosed in ...
