Shaanxi Fast Twin Countershaft Automated Manual Transmission
Shaanxi FAST Twin Countershaft AMT adopts the floating design of spindle and spindle gear. In order to meet the correct meshing and make the load evenly distributed as far as possible, the spindle gear is in radial floating state on the spindle, and the spindle and input shaft adopt floating structure. When working, the radial force of the two intermediate shaft gears on the main shaft gear is equal in magnitude and opposite in direction, and they cancel each other, so that the main shaft can only bear torque, but not bear bending moment, which improves the stress of the main shaft and bearing, and greatly improves the reliability and durability of the transmission. The floating result makes the gear automatically offset part of the manufacturing and assembly errors when meshing, and the meshing zone can easily meet the design requirements, which is beneficial to reduce noise and improve the durability.
