ABC Shock Absorber
Working principle of hydraulic damping shock absorber
Hydraulic shock absorber is the most common use of the current motorcycle shock absorber, is a brief introduction of its working principle.
1, hydraulic damping type rear shock absorber
The structure of the hydraulic shock absorber is similar to that of the suction type pump, and the difference is that the upper end of the hydraulic shock absorber is closed, and the valve is left with a small hole. When the rear wheel meets the raised road surface, the cylinder moves upward, and the piston moves in the cylinder. At this time, the piston valve is pushed upward, in the cylinder cavity of the lower side of the piston oil without any resistance to the piston side. At the same time, this part of the oil through the small holes in the bottom of the valve into the inside and outside the cylinder between the oil chamber. In this way, we can effectively attenuate the impact load of the concave and convex road in the face of vehicle. And when the wheels pass over the raised ground down, the cylinder will follow the downward movement, the piston will move upward with respect to the cylinder. When the piston to move, the oil flushes at the bottom of the valve's flow in cylinder, and cylinder piston on the side of the oil the valve piston holes flow to the lower side. At this point, when the oil flow through the small holes in the process, will be a lot of resistance, so that a better damping effect, played the purpose of shock.
2, telescopic tube type before the hydraulic shock absorber
The front wheel is connected with the front wheel and the frame, which not only plays a part of the supporting role of the skeleton, but also plays the role of the shock absorber. With the mutual extension between the handle and the sleeve, the oil in front of the tube is arranged in the small hole flow in the next door. When the handle is compressed, with the movement of the handle (as shown in Figure 1), the small holes in the B chamber are flowing to the C chamber after the oil pressure in the chamber. At the same time by the free flow of the a room. When the oil flows, the resistance is decreased by the compression force. When the compression stroke speed to the limit, the end of the handle tube mounting cone oil will be inserted, which closed indoor oil passage B. At this time, room B of the oil boom in the in a closed state, thus limiting the handle tube of the trip, effectively prevent the former * between the movable part on the instantaneous mechanical collision.
Room C, orifice flow on the handle tube dilatation (rebound), a chamber of the oil was housed in a former * the upper part of the piston (* near the piston ring in the vicinity). At this point, the flow of oil by the resistance of the attenuation of tension. When approaching the limit of the stretching stroke, the elongation of the spring bounce absorbed vibration energy, and in the process, before the oil * in the lower part of the piston hole added B room, ready for the next work.
