Main Parts
High strength/ high rigidity/ long life block: vermicular cast iron body, similar strength cast steel, similar heat dissipation potential gray iron, strong anti-thermal deformation, high cost, can be adopted in few high end engines in the world due to its core technology.  Good economy; Low nose;. High-integration; Long life.

HW series heavy transmission is a new generation well-crafted product developed by SINOTRUK specially for the heavy duty truck, SINOTRUK own the independent intellectual property rights for it, with its unique structure home and aboard, its primary transmission adopts twin cuntershaft structure and auxiliary transmission adopts planetary deceleration structure, which make its bearing capacity stronger and its structure more reliable. The integrated small housing design allows legible gear and flexible gear shift.Presently, this type of transmission is applied to be engine for the heavy duty truck which power range is 336--420 ps, it is the first choice for the domestic heavy duty truck.
