A method and device for controlling the movement of a synchronizer

Abstract

The embodiment of the present application discloses a method and device for controlling the movement of a synchronizer, including: obtaining a first resistance parameter, which is included in the process of the synchronizer moving from the neutral position to the minimum synchronization point position of the target gear , the thrust received by the synchronizer each time it moves, the target gear is the gear after shifting, and then, according to the first resistance parameter, push the synchronizer to move from the neutral position to the minimum synchronization point position of the target gear, to Make the gear of the vehicle the target gear, thereby successfully completing the gear shift. It can be seen that controlling the movement of the synchronizer according to the resistance parameter can not only ensure that the synchronizer can smoothly change the gear of the vehicle to the target gear, but also, when the thrust required by the synchronizer to complete the shift is known, the gear shift can be performed smoothly. The synchronizer driven by the motor is usually not too large, thereby avoiding the situation that the synchronizer collides with other components due to the excessive movement speed.

Description

technical field [0001] The present application relates to the technical field of synchronizers, in particular to a method and device for controlling the movement of synchronizers. Background technique [0002] At present, the gearbox plays an important role in the shifting process of the vehicle, and the synchronizer in the gearbox is a key component for the gearbox to complete the shifting. During the shifting process of the gearbox, if the thrust of the synchronizer is small, the movement displacement of the synchronizer will be short, resulting in the failure of the synchronizer to move into the gear normally; and if the thrust of the synchronizer is increased to ensure The normal movement of the synchronizer into the gear may cause the thrust of the synchronizer to be too large and the speed of the synchronizer to move too fast, which will cause the synchronizer to collide with other components, thereby causing damage to the synchronizer and other components. Therefore,...

Problems solved by technology

During the shifting process of the gearbox, if the thrust of the synchronizer is small, the movement displacement of the synchronizer will be short, resulting in the failure of the synchronizer to move into the gear normally; and if the thrust of the synchronizer is increased to ensure The normal movement of the synchronizer into the gear may cause the thrust of the synchronizer to be too large and the speed of the synchronizer to move too fast, which will cause the synchronizer to collide with other components, thereby causing damage to the synchronizer and other components

Therefore, for the control quality of the synchronizer, it greatly affects the shift quality of the gearbox, thereby affecting the driver's comfort in driving the vehicle
