What is the principle of motorcycle shock absorption
Shock absorber is an important device for motorcycles, in order to ease and decay the motorcycle in the course of the road due to uneven impact and vibration, to ensure the ride comfort and comfort, is conducive to improving the life of the motorcycle and manipulation Stability, motorcycle are equipped with shock absorber device. Pharaoh big hood for everyone to introduce the working principle of shock absorbers to help you better maintain your car.
Telescopic fork with the front wheel and the frame is linked together, it plays a part of the skeleton support role, but also play the role of shock absorber. With the mutual expansion between the handle and the sleeve, the oil in the front fork is set to flow through the holes in the partition wall. When the handle tube compression, with the handle of the move (as shown in Figure 1), B room after the oil pressure through the hole on the tube to the C chamber. At the same time through the free flow to the A room. When the oil flows, the resistance is attenuated by the compressive force. When the compression stroke is approaching the limit, the tapered oil seal at the end of the handle is plugged in, thus closing the passage of the B chamber oil. At this point, B room hydraulic shocks rise, so that it is in a closed state, thus limiting the stroke of the handle, effectively prevent the fork on the moving parts between the moment of mechanical collision.
The structure of the hydraulic shock absorber is basically similar to that of the inhalation pump. The difference is that the upper end of the steel body of the hydraulic shock absorber is closed and the valve is left with small holes. When the rear wheel encounters a raised road surface, the cylinder moves upward and the piston moves relatively downwardly in the inner cylinder. At this point, the piston valve is washed up, the inner cylinder bore inside the piston oil from any resistance to the piston on the side. At the same time, this part of the oil through the bottom of the valve hole into the inside, outside the cylinder between the oil chamber. This effectively reduces the impact load on the bumps on the vehicle. And when the wheels cross the raised ground to the drop, the cylinder will follow the downward movement, the piston will move relative to the cylinder up. When the piston moves up, the oil flushes the bottom valve to the inner cylinder, and the oil on the upper side of the cylinder cylinder flows to the lower side of the piston valve. At this point when the oil flow through the small hole in the process, will be a lot of resistance, so that a better damping effect, played the purpose of shock absorption.
