Description

A kind of gear ring around automobile synchronizer

technical field

The utility model relates to the technical field of a synchronizer gear ring, in particular to a gear ring surrounding an automobile synchronizer.

Background technique

The shift of the old transmission should use the "two-foot clutch" method. The upshift stays in the neutral position for a while, but the clutch needs to be lifted. The purpose is to synchronize the clutch plate with the flywheel, and the speed must be the same to be able to shift smoothly. If the gear shift is slow and the speed falls to the idle speed, it is impossible to hang in. The downshift should be in the neutral position, while keeping the clutch lifted and the throttle held up to reduce the speed difference of the gears, but this operation is more complicated and difficult to master accurately. Therefore, the designer created a "synchronizer", through which the gears to be meshed reach a consistent speed and mesh smoothly, and the ring gear is one of the important parts of the synchronizer.
