The shock absorber of a high-altitude vehicle is able to ensure relatively sufficient stability in the running of the vehicle. Therefore, the shock absorber of the vehicle has a relatively important relationship with the service life of the aerial work vehicle . The relevant knowledge of the device is that all vehicle drivers need to understand, so that they can know how to perform inspections and repairs when the shock absorber fails. First of all, it should be necessary to make sure that the shock absorber is working properly: 1. Let the high-altitude vehicle drive about 10 km or so on some difficult road conditions and stop. Use your hand to touch the housing of the shock absorber. If it is relatively hot, then it proves that There is no resistance inside the device and the shock absorber does not work. At this time, you can add the appropriate lubricant to enter, and then test again. If you touch the shell if it is hot, then the internal shock absorber oil shortage, you need to add enough oil again, otherwise, it is proved that the reduction Shocker performance fails. 2. Use enough force to press the bumper and release it. If the aerial vehicle has about 3-2 jumps, then it shows that the shock absorber works well. 3. When the aerial working vehicle is in a state of slow running, the emergency brake is applied. Then the vibration of the aerial working vehicle has vibrated from the distance, which shows that there is a problem with the shock absorber. 4, the shock absorber is disassembled to stand upright, and the lower end portion is connected to the ring clamped to the vise, and the frequency of the vibration damping bar is pulled hard, and this time should have enough stable resistance to pull up. The resistance should be greater than the resistance after the downward pressure. If there is no resistance or the resistance is unstable, then the internal parts of the shock absorber may be damaged or lack of oil. It should be replaced promptly. Parts or maintenance. If it is determined that there has been a failure and failure of the shock absorber, it should be checked whether there has been any oil leakage or old oil leakage. If the shock absorber does not leak oil, it should be checked. Whether the connecting rod of the lower shock absorber, the connecting pin, the rubber bushing, the connecting hole, etc., has a place of desoldering, cracking, damage, or falling off. If the above inspections are in normal condition, the shock absorbers should be further disassembled. Check whether the cooperation between the lower cylinder and the piston is too large, whether there is any strain in the cylinder and the sealing of the valve. Whether it is normal, whether the valve seat is attached and the valve flap is not tightly fitted, or whether the tension spring of the shock absorber is broken or is too soft, and replacement parts and repairs are performed according to the corresponding circumstances. In addition, shock absorbers can also be audible during actual use. The main reason is that there is a mutual collision between the shock absorber and the frame, the leaf spring or the shaft, the pad is detached or damaged, the shock absorber is deformed, the oil is not enough for the night, and so on. Faults caused by a series of causes should be promptly identified and repaired.
