Description

Technical Field

[0001] The invention relates to the technical field of synchronizers, in particular to a synchronizer cone ring structure. Background Art

[0002] The old transmission shifts by "two-foot clutching". When shifting up, stay in neutral for a while (but the clutch needs to be lifted up, in order to synchronize the clutch plate with the flywheel, the speed must be consistent to smoothly shift into gear. If the gear shift is slow, the speed will drop to idle speed and it will not be able to shift into gear). When downshifting, step on the accelerator in neutral (while keeping the clutch lifted up) to reduce the speed difference of the gears. But this operation is complicated and difficult to master accurately. Therefore, the designer created a "synchronizer" to make the gears to be meshed reach the same speed and mesh smoothly. At present, the cone ring on the synchronizer is prone to damage after a long period of use. After damage, it needs to be replaced as a whole, which will lead to high maintenance costs. Therefore, we proposed a synchronizer cone ring structure to solve the above problems. Summary of the invention
