The direct-drive advantage
TM4 SUMO high torque motors can interface directly with standard rear differential without the need for an intermediate gearbox.
A direct drive system allows for the following benefits:
- High reliability: removing the gearbox means removing the most mechanically complex and maintenance intensive part of the vehicle
- Easy to fit between the H beam of the truck or in the engine bay of the city bus: no need to modify the vehicle architecture
- Low maintenance: Dana TM4 direct-drive motors require no maintenance
- Fast ROI
