Abstract
The utility model relates to a balance shaft of a two-cylinder diesel engine, a driving cam 2 of a high-pressure oil pump is arranged on the balance shaft, close to the position of a shaft neck 1 at left side, a balance weight 3 is arranged between the driving cam 2 of the high-pressure oil pump and a shaft neck 4 at right side; the balance shaft meets high rotating sped and high load needs of the diesel engine, not only reduces the vibration and noise of the two-cylinder diesel engine, but also is integrated with the driving cam 2 of the high-pressure oil pump of the diesel engine and the balance weight, so as to lead the balance shaft to meet balance requirements of the two-cylinder diesel engine and realize the functions of driving the high-pressure oil pump; while the comfort of the diesel engine is improved, the cost of the diesel engine is reduced, the structure is simplified and simple, the production processing is easy and the practicability is strong.
Description
Technical field
The utility model relates to the trunnion shaft of the trunnion shaft of motor, particularly a kind of two-cylinder diesel.
Background technique
For 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.
The model utility content
The purpose of this utility model 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 deficiencies in the prior art.
The purpose of this utility model realizes in the following way:
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 the two-cylinder diesel that the utility model provides, diesel engine speed can reach more than 4000 rev/mins, satisfy the needs of the high rotating speed of diesel engine, high load, the vibration and the noise of two-cylinder diesel have not only been reduced, 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 utility model.
Embodiment
Be described in further detail below in conjunction with embodiment.
As shown in Figure 1, the trunnion shaft of the two-cylinder diesel that the utility model proposes has the driving cam 2 of high pressure oil pump near the position of left side axle journal 1 on trunnion shaft, has balancer weight 3 between the driving cam of high pressure oil pump and the right axle journal 4.
Claims (3)
1. the trunnion shaft of a 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.
2. the trunnion shaft of two-cylinder diesel as claimed in claim 1 is characterized in that: the driving cam that has high pressure oil pump on trunnion shaft near the position of left side axle journal.
3. the trunnion shaft of two-cylinder diesel as claimed in claim 1 is characterized in that: have balancer weight between the driving cam of high pressure oil pump and the right axle journal.
