Product introduction:

The gearbox flange (also called output flange/drive flange head) is an important component connecting the transmission and the drive shaft. It is mainly used to efficiently transmit the torque output of the transmission to the drive shaft to achieve stable output of the power system. The product is made of high-strength alloy steel or forged material, with strong torsion resistance, high coaxiality, precise installation and other characteristics. It is widely used in heavy trucks such as HOWO, Dongfeng, Shaanxi Automobile, Foton, Jiefang, and engineering machinery equipment.
