Rear matched trailer, steering method of rear matched trailer and shield tunneling machine

The invention provides a rear matching trailer, a steering method of the rear matching trailer and a shield tunneling machine, relates to the technical field of tunnel construction, and aims to solve the problem of deviation of the rear matching trailer in the related technology. The rear matched trailer comprises a trailer body, a rubber coating wheel, a main controller and a sub-controller, the sub-controller is configured to obtain the inclination angle value of the trailer body when the trailer body inclines, and the sub-controller is further configured to judge the inclination angle value of the trailer body and the actual deviation value of the trailer body. The inclination angle value of the trailer is adjusted to be smaller than or equal to the target deviation correction value. According to the method, the deviation of the rear matched trailer can be corrected in real time, the problem of deviation of the rear matched trailer is avoided, and it is guaranteed that the rear matched trailer advances alo
