TMG Drive-train System Products
Our company can replace the transmission,gearbox and torque converter. Compared with the big international brands, the replacement products of our company have more advantages in performance and price.We could come up with plans to replace the gearbox for 6-20 ton underground loaders.
1.Customized design to solve customer pain points
2.Short lead time, 3 months;
3.Electrically controlled shifting and automatic shifting mode are adopted to reduce shifting impact and protect gears from damage;
4.Hydraulic torque converter has large circulation, large transmitted torque, large traction and strong climbing ability. Change Torque is not easy to heat up.
5.The clutch structure is improved to reduce the friction plate burning phenomenon caused by the inaccurate control of the engagement time of the two clutches during the shifting process.
6.The gear is thickened to improve the reliability of the gearbox. Higher reliability and longer life.
