Synchronizer gears for trucks and buses
Guaranteed quality has made the brand DT Spare Parts the leading brand in the international Independent Aftermarket for commercial vehicles. The complete range includes all required spare parts for trucks, trailers and buses, including all standard synchronizer gears.
During the gear shifting, the shift collar is pushed to the gearwheel. In the process, the locking piece pushes the synchronizer ring onto the conical part of the gearwheel.
Through the friction of the synchronizer ring, the gearwheel is accelerated or decelerated. The synchronizer ring is supported over the lugs on the shifting body. Due to the play in the lugs on the shifting body, the synchronizer ring is repositioned by about a half a tooth width and thus blocks the shift collar’s way into the gap in the teeth of the gearwheel. Once the synchronization is established, there is no longer radial force acting on the synchronizer ring.
Due to the chamfering on the end faces of the shift collar and synchronizing ring, the synchronizer ring is turned back. The tooth spaces become free and the shift collar can be slid over the teeth. The gear is engaged.
Quiet synchronization is guaranteed by precisely coordinated gear teeth.
The synchronizer rings are forged. This production method ensures a more consistent tooth form with high strength.
