The invention discloses a four-wheel steering mechanism with two freedom degrees. The four-wheel steering mechanism comprises a steering rod and a differential mechanism. A steering wheel and the steering rod are fixedly connected together and transmit actuating input with two freedom degrees to the differential mechanism, then the differential mechanism is used for synthesizing the two parts of actuating input and then outputting other two actuating parts which are linearly independent, and the two actuating parts are transmitted to a front steering transmission rod and a rear steering transmission rod so as to drive front wheels and rear wheels of an automobile to steer, wherein the front steering transmission rod and the rear steering transmission rod controls the front wheels and the rear wheels of the automobile to steer respectively. The steering angle of the front wheels and the steering angle of the rear wheels of the automobile are also linearly independent. A driver can rotate and swing the steering wheel and the steering rod which are fixedly connected to enable the front wheels and the rear wheels of the automobile to steer in the same direction and at the same angle, or steer in the same direction and at different angles, or steer in different directions and at the same angle, or steer in different directions and at different angles, so that flexibility of low-speed turning and stability of high-speed turning and lane changing of the automobile are improved.
