Synchronizer gears for trucks and buses

lpxGym7cS9g

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.

The DT brand products, made of high quality materials, meet your highest quality requirements and guarantee a long period of use.

Synchronizer gears form the transition between gearwheel and shift collar. Through friction, they bring both wheels of the required gear to the same rotational speed, so that this can be engaged without declutching.

DT-Technic Info

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.

The friction surfaces of the synchronizer rings are coated with Molybdenum. This protective layer is characterized by excellent frictional properties and guarantees minimum wear during the synchronization.

 Construction of synchronizer gears

  1. Gear teeth
  2. Molybdenum coating
  3. Friction surface
  4. Clamping cone


In addition to synchronizer rings, DT Spare Parts also offers all standard gearbox parts.
