Principles of operation of the car springs

An elastic (springs or tweezers) that does not have a damper (also known as a springboard) is unbelievable. So what is hidden in the duty of a damper? nhipxe Actually the pavement never completely corresponds with the direction of the vehicle in the process of moving, always forming the vibration effect on the wheel, and thereby transmitted to the body and the driver … spring to Impulse reduction, but it itself is vibrating in the impact pulse from the road surface and the weight of the car over. The oscillation of the car body and loofus will last a long time if it is not destroyed, the car after a bump will be float like a boat for a long time after and bring much risk. potential in traffic.

The main function of the duct is to extinguish the free vibrations mentioned above, depending on the principle of operation people can be divided into several types of ducts as follows: 1 tube type 2-tube suction cup Two pressure suction hose -Vario bounce -switches with steam springs Hydraulic shock absorber 1-tube duct type 2: This is the type of duct used commonly in cars, trucks. In one oil filled pipe one piston is moved, another pipe covers the first. In the middle of the two tubes form a small space and it is used to balance the amount of POTTON oil that comes from the oil chamber. On the piston body and the base of the oil chamber, the throttle body is arranged. Finally, there is a common pipe for the duct. The piston shaft is connected to the chassis, the opposite end of the oil hose is connected to the wheel suspension. As the car swung down, the thrust of the oil-injected pistons flowed through the valve on the piston surface to the top of the oil chamber, along with the penetration of the crank shaft. More force was forced into the valve at the bottom of the tube. contains the oil, and spills out of the space between the two pipes as described above, so the main function of the space between the two tubes as mentioned above is to compensate for the amount of oil displaced by the process of bobbing up Shunting of the piston due to the presence of the piston shaft in the oil chamber space (not trapped). When the diffuser inflates the opposite process, the oil from the upper chamber runs through the reverse valve downward, simultaneously with the oil from the outer chamber running back through a second valve at the bottom of the oil chamber. This is a duct type with long life, good fluctuation, the most disadvantage is the leakage of oil through the slots, more accurate installation, only to be driven in a direction, Frequent shaking horizontal (sloping terrain, running on hilly side) will quickly damage the type 2 duct above. 2- type of tube: The principle of work is not much different than the two types mentioned above, the only thing is that no second pipe covers the outside, the oil compensating function is taken by a chamber below the chamber Oil work as shown below: Oil chambers and air chambers are separated by a free and sealed piston, both oil and vapor undergo a pressure of around 20 to 30 Bar when the car is moving and has a bump! As the car swung down, the main piston shaft (with throttle valve) pressed deep into the oil chamber, the pressure also created the force to open the oil drain valve to the upper chamber as the two-tube damper, however, when the piston rod Deepening reduces the volume of the oil chamber (while the oil volume remains constant), causing the oil pressure to rise strongly, pushing the “Free” pistons (without valves) into the lower chamber. The flexible spring is elastic by the mass of the bottom, as opposed to the movement of the pressure caused by the vehicle, to quickly improve the damping process. The principle diagram can be represented by two springs (spring and cushion spring acting as springs) with the same “pitch” oscillating and the same “phase”, which is the reason that oscillates. In the vehicle layout type A suspension tube better than the type Two tubes. One tube is often more expensive, due to the complexity of making sealing rings around the piston shaft and oil casing. The same type of extinguishers (for example, same type of vehicle), the type 1 pipe extinguishes vibration faster, not only because of the more diverse operating principle, but also because of the same size of the duct Piston Oil presses can be made with larger diameters. In addition, due to the increased working pressure of the oil, the bubbling of the oil (causing rapid aging) is also very limited, although the compressors work higher pressure but are better heat, because no There is a layer of “Outer jacket” wrapped “outside as the type on two ducts. In short: Instead of allowing the oil to escape relatively freely through the valves (valves open when the pressure reaches the threshold value) into the buffer zone as in the 2-pipe type when the pressure is strong, Both oil and steam are sealed, the oil pressure can only compress to the gas, causing the elasticity to vary with the degree of steam action, which is an improvement on how it works. 3- type 2-tube with pressure steam: Combining the superiority of the two types, they make oil-gas combination duct,
