Abstract
The invention relates to a balance shaft of a two-cylinder diesel, a driving cam 2 of a high-pressure oil pump is arranged near the left shaft neck 1 of the balance shaft, and a balance weight 3 is arranged between the driving cam and the right shaft neck 4 of the high-pressure oil pump; the balance shaft of a two-cylinder diesel can meet the requirements of high rotation and high load for the diesel, and can reduce the vibration and noise of the two-cylinder diesel; simultaneously, the balance shaft integrated with the driving cam and the balance weight of the high-pressure oil pump of the diesel not only meets the balance requirement of the two-cylinder diesel, but also realizes the function of the driving high-pressure oil pump; and the invention improves the comfort of the diesel and decreases the cost of the diesel, and has simple structure, easy production and processing and high practicality.
Description
Technical field
The present invention relates to the trunnion shaft of the trunnion shaft of motor, particularly a kind of two-cylinder diesel.
Background technique
Be the vibration of satisfying diesel engine and the requirement of smoothness, need to increase vibration and the noise that trunnion shaft reduces complete machine on two cylinder diesels.The function of two traditional cylinder diesel trunnion shafves is the function of single trunnion shaft.Up to now, do not see the structure of integrated high voltage oil pump driving cam and balancer weight on two cylinder diesels as yet.
Summary of the invention
The object of the invention aims to provide a kind of trunnion shaft of two-cylinder diesel, has both satisfied two-cylinder diesel and has reduced complete machine oscillation and noise requirement, can drive high-pressure fuel pump of diesel engine again, to remedy the deficiency of existing technology.
The object of the invention is realized through following mode:
A kind of trunnion shaft of two-cylinder diesel is characterized in that in the integrated driving cam and the balancer weight of high pressure oil pump between the left and right axle journal on the trunnion shaft.
The trunnion shaft of two-cylinder diesel provided by the invention; Diesel engine speed can reach more than 4000 rev/mins; Satisfy the needs of the high rotating speed of diesel engine, high load, not only reduced the vibration and the noise of two-cylinder diesel, the simultaneously integrated high pressure oil pump driving cam and the balancer weight of diesel engine; Make trunnion shaft both satisfy the balance requirement of two-cylinder diesel, can realize driving the function of high pressure oil pump again.When improving the travelling comfort of diesel engine, can reduce the cost of diesel engine, simplified structure, it is simple in structure, production and processing is easy, practical.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Make further detailed description below in conjunction with embodiment.
As shown in Figure 1, the trunnion shaft of the two-cylinder diesel that the present invention proposes has the driving cam 2 of high pressure oil pump near the position of left side axle journal 1 on trunnion shaft, between the driving cam of high pressure oil pump and the right axle journal 4, has balancer weight 3.
