1. Transmission system

1.1 General description
The transmission system of the three wheeled forklift truck includes transmission
system we call traditionally and brake system. Front wheel dual driving motor structure
makes the right and left wheel of three wheeled truck has drive axle, redactor, brake and
driving motor independently to improve working efficiency. Transmission unit is
assembled inside of drive axle housing while brake is assembled on motor shaft. The
structure is compact.
Truck travelling speed is increased with the increase of motor speed; travelling
direction is changed with motor rotation direction; The sensor installed on rear wheel
sends information to drive motor controller on right and left front wheel, after receiving
different information, right and left front wheel give out different speed and thus steering
of the truck is realized. The steering of the three wheeled truck is realized through electric
differential. The system has no bevel gear which thus not only improves working
efficiency but also reduce bevel gear noise.
1.1.1 Front wheel assembly
Front wheel is made up of solid tyre and rim. Refer to the following for front wheel
