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 oil pump, 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
The present invention relates to the trunnion shaft of the trunnion shaft of motor, particularly a kind of three-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 the three-cylinder diesel.The function of traditional three-cylinder diesel trunnion shaft 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 three-cylinder diesel as yet.
Summary of the invention
The present invention provides a kind of trunnion shaft of three-cylinder diesel, has both satisfied three-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 three-cylinder diesel is in integrated high pressure oil pump driving cam and balancer weight between the left and right axle journal on the trunnion shaft.Said high pressure oil pump driving cam is near left axle journal; Balancer weight is between high pressure oil pump driving cam and right axle journal.
The trunnion shaft of the three-cylinder diesel that the present invention proposes; 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 three-cylinder diesel, the simultaneously integrated high pressure oil pump driving cam and the balancer weight of diesel engine; Make trunnion shaft promptly satisfy the balance requirement of three-cylinder diesel, can realize driving the function of high pressure oil pump again; Further reduce the cost of diesel engine when improving the travelling comfort 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
Below in conjunction with embodiment the present invention is made further detailed description.
As shown in Figure 1, the trunnion shaft of the three-cylinder diesel that the present invention proposes is having high pressure oil pump driving cam 2 and balancer weight 3 between left axle journal 1 and the right axle journal 4 on the trunnion shaft, and wherein, high pressure oil pump driving cam 2 is near left axle journal 1; Balancer weight is between high pressure oil pump driving cam and right axle journal.
Claims (1)
1. the trunnion shaft of a three-cylinder diesel is characterized in that: in integrated high pressure oil pump driving cam and balancer weight between the left and right axle journal on the trunnion shaft; Said high pressure oil pump driving cam is near left axle journal; Balancer weight is between high pressure oil pump driving cam and right axle journal.
