The output torque of a vehicle engine is a cyclically varying load, and the ground often experiences alternating loads during the operation of a high-altitude vehicle that reacts to the drivetrain, causing torsional vibration of the drivetrain, if the frequency of these external excitations and the natural frequency of the drivetrain As it approaches, severe resonance occurs in the system, resulting in reduced ride comfort and shortening the service life of transmission components. The torsional damper is mainly composed of a damper spring that acts as a buffer and a damper that damps vibration.
The working platform of the aerial working platform consists of six rectangular windows on the driven plate body, the driven hub and the damper end cover. The damper spring is installed along the circumferential direction in each window, and the driven plate body and vibration damping are arranged in each window. The window of the cover of the device is provided with a cuff so that the spring does not come out. This design can achieve an elastic connection between the driven plate and the driven disk in the process of transmitting the torque to the driven hub. The end cover of the damper and the driven plate body are connected together by rivets, and the driven plate hub and the damper plates on both sides thereof are sandwiched in the middle, and the vibration energy is consumed by the damper plates to achieve the purpose of vibration reduction.
What is the cause of the incomplete separation of the clutches for aerial vehicles?
When the aerial vehicle starts, the clutch pedal is stepped to the end, and it is still difficult to catch the gear or cannot catch the gear, and the transmission gear makes a collision sound; or the vehicle starts or the engine stalls before the gear is attached but the clutch is not lifted. The main reasons are the following:
1 The free travel of the clutch pedal is too large;
2 The separation lever adjustment height is not on the same plane or the lever inner end is too low;
3 The driven plate is warped, the rivet is loosened, the friction plate is damaged or the newly replaced friction plate is too thick, and the driven plate is installed in the opposite direction.
4 Double-disc type clutch The intermediate drive plate limit screw is not properly adjusted, or the separation spring is too soft, broken, or the intermediate pressure plate is worn too thin.
5 The drive hub hub and the key shaft of the transmission shaft are rusted, making it difficult to move the driven plate.
6 The hydraulically operated clutch of the hydraulically operated clutch has a loophole or air.
