Abstract

The invention relates to a balance shaft of a three-cylinder diesel, a driving cam of a high-pressure oil pump and a balance weight are integrated between a left shaft neck and a right shaft neck on a balance shaft, and the driving cam of the high-pressure oil pump is near the left shaft neck; the balance weight is arranged between the driving cam and the right shaft neck of the high-pressure oilpump, when the balance shaft of a three-cylinder diesel is utilized, the rotation speed of the diesel can reach more than 4000 turns / min, the balance shaft of the three-cylinder diesel can meet the requirements of high rotation speed and high load for the diesel, and can reduce the vibration and noise of the three-cylinder diesel; simultaneously, the balance shaft integrated with the driving cam and balance weight of the high-pressure oil pump of the diesel not only meets the balance requirement of the three-cylinder diesel, but also realizes the function of the driving high-pressure oil pump; and the invention improves the comfort of the diesel and simultaneously decreases the cost of the diesel, and has simple structure, easy production and processing and high practicality.

Description

technical field [0001] The invention relates to a balance shaft of an engine, in particular to a balance shaft of a three-cylinder diesel engine. Background technique [0002] In order to meet the vibration and smoothness requirements of the diesel engine, a balance shaft needs to be added to the three-cylinder diesel engine to reduce the vibration and noise of the whole machine. The function of the balance shaft of the traditional three-cylinder diesel engine is only the function of a single balance shaft. So far, there has not been a structure integrating a high-pressure oil pump driving a cam and a balance weight on a three-cylinder diesel engine. Contents of the invention [0003] The invention provides a balance shaft of a three-cylinder diesel engine, which not only meets the requirements of the three-cylinder diesel engine to reduce the vibration and noise of the whole machine, but also can drive the high-pressure oil pump of the diesel engine to make up for the de...
