The invention discloses a multi-connecting-rod steering mechanism suitable for a train bogie, which comprises the bogie, a front wheel and a rear wheel arranged on the bogie, a controller, a driving motor and two multi-connecting-rod structures, the two multi-connecting-rod structures are respectively arranged on two sides of the bogie, and the multi-connecting-rod structures are respectively connected with axles of the front wheel and the rear wheel. The driving motor is connected with the multi-connecting-rod structure, and the controller is connected with the driving motor. According to the method, the requirement for machining precision of key components is lowered, the system fault-tolerant rate is increased, the curve passing ability and the driving stability of the railway vehicle are improved, impact on a rail is reduced, the service life of a wheel rail is prolonged, and the method has wide application prospects and use value and is worthy of application and popularization.
