The invention belongs to the technical field of driving wheels, in particular to a travelling platform. The travelling platform comprises a bearing plate, a first rotating shaft, a supporting plate, travelling wheels and a driving motor. A first driving shaft rotates to drive a first driving wheel mounted on the first driving shaft to rotate. The first driving wheel rotates to drive a first driving gear to rotate. The first driving gear is engaged with three teeth on a corresponding travelling wheel shell, a third driving gear is engaged with three teeth on a corresponding travelling wheel shell, and a fourth driving gear is engaged with three teeth on a corresponding travelling wheel shell. The third driving gear and the fourth driving gear are engaged with a second driving wheel and a third driving wheel correspondingly. A second transmission gear and a fourth transmission gear are engaged with a third transmission gear and a first transmission gear correspondingly. The first drivingwheel, the second driving wheel and the third driving wheel as well as the first driving gear, the third driving gear and the fourth driving gear can be driven mutually. The second transmission gearand the fourth transmission gear as well as a fifth transmission gear and the first transmission gear can be driven mutually. The automatic speed changing function of the travelling wheels is achievedthrough engaging of the gears.

The invention discloses a dual-motor electric power-assisted steering system based on synchronizer, and a method thereof. A main motor and an auxiliary motor perform torque coupling through a shaft-fixed gear unit, and the coupled torque is output through a planet carrier through a planet gear unit; the planet carrier output shaft is connected with a second steering shaft in parallel through a torque coupler, the torque coupler outputs the torque to a steering device; and an output end of the steering plate torque corner sensor, a control end of the main motor, the control end of the auxiliarymotor, and the control end of the electromagnetic clutch are connected with a controller. By arranging two power-assisted motors connected through the planet gear unit and the shaft-fixed gear unit,the main motor is controlled to singly perform power assisting, or the main motor and the auxiliary motor commonly output the torque according to the vehicle speed signal and the steering plate torquesignal, the demand that the commercial vehicle needs large power-assisting torque is satisfied, the fuel economy of the commercial vehicle is improved, and the transportation cost is reduced.
