Shaanxi Fast 7 Speed Energy Powertrain Transmission

FAST 7 Speed Energy Powertrain Transmission series is a transmission assembly specially developed by Shaanxi Faster Automotive Transmission Group for pure electric vehicles. The input torque of this series is 2000 N.m, with seven gears. Mainly used in heavy trucks above 30T and mining dump trucks; The series transmission design is novel, using a single box structure, full sliding sleeve shift, simple structure, high reliability, long service life. Transmission speed ratio configuration is reasonable, the use of fine and high tooth design, gear meshing smooth, transmission noise is low, clear gear, flexible shift, a variety of control forms, can use electric, pneumatic structure. Advanced production technology. The processing of each part of the transmission has the international advanced machine tools (mainly numerical control, machining center), heat treatment equipment (IPSEN continuous furnace and Aixelin box furnace) as the guarantee, the production of important parts in the special production line.

Advantages of 7 Speed EV

1. Adopt special sliding sleeve, cancel synchronizer structure, greatly reduce transmission assembly failure.
2. The pneumatic gear shifting actuator adopts the direct shift mode, the shift time is less than 0.6s, and the shift is smoother. It has been through more than 30 million consecutive bench experiments, with high reliability and fully meeting the life cycle.
3. Effectively improve the driving range of the vehicle, extending the driving journey by more than 20% (compared with direct drive).
4. The system has high transmission efficiency, advanced control technology and wide range of vehicle application.
