Abstract
The invention discloses an air intake and exhaust sleeve which comprises a balance shaft and oil plugs arranged at two ends of the balance shaft, wherein a fixed flange is arranged on an oil plug at one end of the balance shaft, and at least one installation hole is formed in the middle of the balance shaft. The air intake and exhaust sleeve is simple in structure, low in cost and porosity and excellent in quality, and can well meet requirements of an automobile for stability, the comfort and the safety of an automobile body in high-speed running process.
Description
Technical field
The present invention relates to a kind of auto parts machinery, relate in particular to a kind of intake and exhaust cover.
Background technique
On air inlet cover and the trunnion shaft support of exhaust flange use in automobile engine cylinder-body.Air inlet cover and exhaust flange part on the low-grade car are short and small, are easy to die casting; Air inlet cover on the medium-to-high grade automobile and exhaust flange part are bigger about 3 times than the air-casing on the low-grade car, so in order to satisfy automobile stationarity, travelling comfort and security requirement to car body in the high speed operation process better, need carry out structural research and quality control to the intake and exhaust cover.
In addition, this product almost by external import, causes the cost height, so need this product of exploitation badly to alleviate inlet pressure.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, a kind of low porosity, intake and exhaust cover that cost of production is low are provided.
Technological scheme: in order to realize above purpose, a kind of intake and exhaust cover of the present invention, it comprises trunnion shaft, is located at the plug cock at trunnion shaft two ends, the plug cock of an end is provided with fastening flange therein, is provided with at least one mounting hole in the middle of described trunnion shaft.
Described mounting hole is provided with two.
The pore size of described intake and exhaust cover is smaller or equal to 0.5mm, and the pore spacing is not more than 5mm.
Beneficial effect: intake and exhaust nested structure provided by the invention is simple, with low cost, and porosity ratio is low, and good quality can satisfy automobile stationarity, travelling comfort and security requirement to car body in the high speed operation process better.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
Intake and exhaust cover as shown in Figure 1, it comprises trunnion shaft 1, is located at the plug cock 2 at trunnion shaft 1 two ends, the plug cock 2 of an end is provided with fastening flange 3 therein, is provided with two each and every one mounting holes 4 in the middle of described trunnion shaft 1.The pore size of this intake and exhaust cover is smaller or equal to 0.5mm, and the pore spacing is not more than 5mm.
The present invention is installed in the spindle balance system in the motor, wherein in use, by mounting hole 4 and fastening flange eccentric weight is installed on the trunnion shaft 1, this eccentric weight rotates synchronously with bent axle, and the reversal of vibrations power of utilizing this eccentric weight to produce makes motor obtain good balance.This spindle balance system can reduce the vibration of motor effectively, thereby the vibration that slows down vehicle reduces the noise of motor, prolongs motor working life, improves the travelling comfort of driving.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All spirit essence has been done according to the present invention equivalents or modification all should be encompassed within protection scope of the present invention.
