The working principle of the gearbox synchronizer is an important part of the automobile transmission, and its function is to ensure the smooth and accurate shifting process. The following is a detailed introduction to the working principle of the gearbox synchronizer.
1. basic concepts
The gearbox synchronizer is a mechanical device, mainly used in the shifting process of automatic transmissions to ensure smooth meshing of gears. It controls the gear speed so that the gear speed is the same when shifting, thereby avoiding impact and noise.
2. working principle
1. Identify shift demand: When the driver generates different driving speed or gear demand by operating the accelerator pedal and the brake pedal, the gearbox will receive the shift signal.
2. Synchronizer function start: The synchronizer starts to work according to the received shift signal. It adjusts the speed of the corresponding gear to match the speed of the gear to be engaged.
3. Speed synchronization process: During the shifting process, the friction surface of the synchronizer is in contact with the adjacent gears, and the speed of the adjacent gears is gradually approached by friction until synchronization is reached.
4. Gear meshing: When the speed is synchronized, the synchronizer will control the shift fork groove or shift fork to make the gears mesh accurately. At this time, the shift process is completed and the vehicle continues to run smoothly.
3. Key Features
1. High efficiency: The synchronizer can quickly adjust the gear speed to ensure the rapid completion of the shifting process.
2. Ride comfort: Through the work of the synchronizer, the shifting process becomes very smooth, almost no impact.
3. Accuracy: The synchronizer can ensure the precise meshing of the gears and avoid damage caused by misoperation.
4. maintenance
In order to ensure the normal operation of the synchronizer, it is necessary to replace and clean the transmission oil regularly to avoid the wear of the synchronizer caused by sludge and impurities. In addition, regularly check the grinding of the synchronizer.
