Abstract
The utility model discloses an air intake and exhaust sleeve which comprises a balance shaft and oil plugs arranged at two ends of the balance shaft, a fixed flange is arranged on one of the oil plugs at one end of the balance shaft, and at least one installation hole is arranged in the middle of the balance shaft. The air intake and exhaust sleeve is simple in structure, low in cost and porosity and good in quality, and capable of meeting the requirement of stability, comfort and safety of a car body during high speed moving process.
Description
Technical field
The utility model relates to a kind of auto parts machinery, relates in particular to a kind of intake and exhaust cover.
Background technique
Air inlet cover and exhaust flange are used on the trunnion shaft support 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, need carry out structural research and quality control to the intake and exhaust cover in order to satisfy automobile stationarity, travelling comfort and security requirement to car body in the high speed operation process better.
In addition, this product almost leans on external import, causes cost high, so need this product of exploitation badly to alleviate inlet pressure.
The model utility content
Goal of the invention: the purpose of the utility model is in order to solve the deficiency of existing technology, and 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, the described a kind of intake and exhaust cover of the utility model, 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, in the middle of said trunnion shaft, is provided with at least one mounting hole.
Described mounting hole is provided with two.
The pore size of said intake and exhaust cover is smaller or equal to 0.5mm, and the pore spacing is not more than 5mm.
Beneficial effect: the intake and exhaust nested structure that the utility model provides 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 the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model.
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, in the middle of said trunnion shaft 1, is provided with two each and every one mounting holes 4.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 utility model in use; Be installed in the spindle balance system in the motor; Wherein, through mounting hole 4 and fastening flange eccentric weight is installed on the trunnion shaft 1, this eccentric weight rotates with bent axle synchronously; 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.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
