Because the motors with the same frequency, rotating speed and power are adopted and matched with the speed reducers with the same reduction ratio, the rotating speed synchronization can be basically kept in the driving process. In addition, the reduction gear is high (the rotating speed of the motor is 1400 revolutions per minute, and the output rotating speed of the reduction gear is 1 revolution per minute), so the torque transmitted to the drive wheel is also high.
Although the difference of the rotating speed is not large due to various reasons such as the diameter of the driving wheel, the levelness of the track, the load of the bridge body and the like, the driving wheel cannot walk uniformly in actual operation, and a driving wheel shaft seat is always broken and derailed seriously due to large torque. These disadvantages affect on the one hand the normal production and on the other hand the maintenance costs are also high.

Preferably, the speed reducer is fixed on the bridge body, the center of the bottom of the bridge body is provided with a mounting bracket, and the differential transmission device is fixed on the mounting bracket.
The beneficial technical effects obtained by adopting the technical scheme are as follows:
the output power shaft of the speed reducer and the coaxial chain wheel are driven by friction plates, and the transmission torque is adjustable. When the torque is too large to exceed the bearing capacity of the transmission parts due to uneven transmission or special reasons, the friction sheet can (slip) protect the weak links of the transmission parts from being damaged.
After the differential transmission device is used for driving, a motor and a speed reducer can be omitted.
The original design is to use two output torques to be 2840Nm, the utility model discloses only use one of them speed reducer. Compared with the prior art, the load transmitted is small, the driving wheel base (bearing seat) cannot be damaged greatly, and derailment and bridge falling are not easy to occur.
The differential drive automatically adjusts the drive during travel.
The speed reducer transmits power to the differential transmission device through the chain wheel and the chain to input power. The differential transmission device converts power into torque output through a gear and a planetary gear, and transmits the torque to a driving wheel of a mud suction bridge through a universal joint and a transmission shaft. The differential transmission device is characterized in that two output wheel shafts can rotate in a differential mode, one shaft can be completely fixed, and the other shaft can rotate in a double mode. Two driving wheels of the mud suction bridge cannot stop in a starting state, when one driving wheel is difficult to walk due to deviation in the advancing process, the rotating speed is reduced, the other driving wheel can continue to rotate for correcting the deviation, and therefore the mud suction bridge can be automatically adjusted and corrected to normally walk. In the simplest way, no matter whether the road surface is flat or not, as long as the front direction wheels are right, the two wheels on the drive axle can automatically adjust the rotating speed through the differential transmission device in the advancing process.
