The synchronizer compression spring plays an important role in the locking ring synchronizer working process. The stiffness and working length design of the compression spring are the two major aspects to influence synchronizer working. The stiffness is important to synchronizer pre-locking, and the working length design is related with the structural arrangement and form of the synchronizer. The impact of the spring stiffness to the synchronizer locking reliability was mainly analyzed. Through theoretical analysis, transmission assembly bench test and vehicle road running test, the importance of synchronizer compression spring design was clarified in detail and in-depth. It has a considera- ble reference significance.
