The invention discloses a hydraulic differential mechanism for a shield carrier. The hydraulic differential mechanism comprises a swing oil cylinder, a pilot valve is arranged on the swing oil cylinder, a cam is arranged on the lower portion of the swing oil cylinder, a two-position three-way valve is arranged at the end of the swing oil cylinder and connected with a closed pipeline, and a pressure cut-off valve is arranged inside the closed pipeline. According to the hydraulic differential mechanism for the shield carrier, by the aid of the swing oil cylinder, a feedback control function is achieved, errors are eliminated, pump displacement control precision is high, consistent pressure of the closed pipeline is kept by displacement of a control pump in steering, tire wear degree is decreased, and normal steering cannot be affected.
