Suitable for the engine: 4HG1 4HE1
Gear box spare parts The failure of the synchronizer ring in service is due to wear.There are four main forms of wear, namely adhesive wear, fatigue wear, abrasive wear and oxidation wear.Although various kinds of friction wear have their related surface morphology, the formation and propagation mechanism of cracks exist in the wear process.The results show that the main wear pattern of the synchro gear ring is adhesive wear, and the wear resistance can be improved by controlling the crack formation and expansion of the material
Brass as synchronizer ring is developed internationally in recent years, especially in the automotive field is particularly outstanding .The effect of heat treatment process on the microstructure and properties of HMN59-2-1-0.5 manganese brass ring. The results show that the structure and properties of ring ≤ 5% and HB=168±8 can be satisfied by direct air cooling, air cooling and solid solution at 750℃ for 1h after hot precision forging.After direct air cooling and aging treatment, the wear resistance of the ring reached the same level as that of the same ring in Germany.
