Steering device of tracked vehicle steering wheel and control method

The invention discloses a tracked vehicle steering wheel steering device and a control method. The tracked vehicle steering wheel steering device comprises a straight operation mechanism, a steering wheel operation mechanism, a tracked chassis, a controller and a hydraulic motor. The crawler chassis is fixedly installed on the crawler supports above the left side crawler and the right side crawler, the crawler chassis is used for installing the straight-moving operation mechanism, the steering wheel operation mechanism, the controller and the hydraulic motor, and the straight-moving operation mechanism is used for controlling the crawler to move forwards and backwards. The steering wheel operating mechanism transmits the rotating angle to the controller through the angle encoder, the rotating angle and the rotating direction of the first motor or the second motor are further adjusted through the controller on the basis of the action of the gear shifting handle, the rotating speed difference is generated betwe
