How do the clutch air pressure bearings work together during the gearshift process?
Publish Time: 2024-11-05
During the gearshift process, the clutch air pressure bearings play a vital role in coordination.
When the driver starts the gearshift operation, the clutch begins to disengage first. At this time, the air pressure system of the clutch air pressure bearings begins to work. The air pressure acts on the bearings to produce precise displacement, ensuring that the clutch plate can be separated from the flywheel smoothly and quickly. This separation process requires the air pressure bearings to provide appropriate support force and separation speed to avoid excessive wear of the clutch plate or incomplete separation.
At the moment of shifting, the gear ratio inside the gearbox changes. The clutch air pressure bearings must maintain a stable working state to ensure that the clutch is in a disengaged state to prevent abnormal power transmission when the gear is switched. At the same time, the air pressure support it provides can effectively absorb the impact force generated during the gearshift process and reduce damage to other parts inside the gearbox.
As the new gear begins to mesh, the clutch air pressure bearings accurately adjust the air pressure according to the instructions of the control system, so that the clutch plate gradually and smoothly re-engages. This process requires the bearing to be able to adjust its pressure and displacement according to different gear shifting situations to ensure that the engagement pressure between the clutch plate, flywheel and pressure plate is moderate. If the air pressure is not adjusted properly, it may cause the engagement to be too slow, affecting the shifting speed, or the engagement to be too fast, causing impact and damaging the transmission system.
Moreover, during the entire shifting process, the Clutch air pressure bearings work closely with the hydraulic control system and electronic control unit of the gearbox. The electronic control unit sends instructions to the control module of the air pressure bearing according to parameters such as vehicle speed and engine speed, and adjusts the air pressure, so that the Clutch air pressure bearings can perfectly cooperate with the gearbox in the shifting operation under different working conditions, ensuring the smoothness, rapidity and reliability of the shifting, and improving the performance of the entire vehicle transmission system.
