A kind of manufacturing method of automobile shock absorber rubber bushing
新闻概况： The shock absorber is used to suppress the shock of the spring and absorb the energy of the road impact when it rebounds after shock absorption. When driving a vehicle with a broken shock absorber, the car will bounce when it passes through potholes or undulating roads, the car parts are easily damaged, the noise inside the car is increased, and the occupants are also very uncomfortable. The shock absorber is used to restrain This bouncing. Without a shock absorber, the rebound of the spring will not be controlled. When the car encounters a rough road, there will be serious bouncing. When cornering, the tire will lose grip and tracking due to the vibration of the spring. handling stability.
What are the rubber bushings in the car suspension for?
In fact, most of the rubber parts on automobiles are inseparable from the original intention of "buffering vibration isolation". For example, the invention of tires - tires were first used on bicycles. The first bicycles had no tires, and the road conditions in that era were very poor, either unpaved roads or stone roads, on which bicycles were driven. It is very uncomfortable for the cyclist, and it also limits the speed of the ride
Classification of oil seals?
1. It can be classified according to the type of sealing medium: oil seals for gas sealing, oil seals for fluid sealing, oil seals for grease sealing; 2. It can be classified according to the shape of the seal: for the rotating shaft (inner seal), oil seal for the rotating casing (outer seal);
Introduction and classification of oil seals
Oil seals are mainly used to seal oil seals in rotary motion. Most of the main oil seals are equipped with springs as the main source of seal contact pressure. Due to the metal spring's resistance, fatigue resistance (long-term use without stress attenuation), and its good adjustability (spring length adjustment), and because the oil seal lip is not directly installed in the groove like the "O" ring It is connected to the skeleton through a certain flexible waist, so that it has a certain adaptability (that is, the machining accuracy does not need to be as high as the "O" shape, allowing a certain degree of eccentricity). The new oil seal is widely used in general After continuous research, new oil seals with long life and high speed are also being developed.
The concept of valve oil seal
The valve oil seal can prevent oil from entering the intake and exhaust pipes, causing oil loss, preventing the leakage of gasoline and air mixture and exhaust gas, and preventing engine oil from entering the combustion chamber. Valve oil seal is one of the important parts of the engine valve group. It is in contact with gasoline and oil at high temperature. Therefore, it is necessary to use materials with excellent heat resistance and oil resistance, generally made of fluororubber.
