The invention discloses a hinged type passenger car mechanical connecting device. The hinged type passenger car mechanical connecting device comprises a front carriage traction frame, a rear carriage traction frame, a middle bearing cross beam and a round floor. One end of the middle bearing cross beam is connected with a protection plate a through a fixing shaft. The other end of the middle bearing cross beam is connected with a middle frame through a protection plate b. The traction frames are symmetrically arranged on the two sides of the middle bearing cross beam and are the front carriage traction frame and the rear carriage traction frame respectively. An oil injection hole cover plate is arranged inside the middle bearing cross beam. Equally-divided components are symmetrically arranged on the two sides of the fixing shaft. The two ends of the equally-divided components are connected with the traction frames and the fixing shaft respectively, and the front carriage traction frame and the rear carriage traction frame are fixedly connected with the round floor. Telescopic tents are symmetrically arranged on the two sides of the middle frame. The hinged type passenger car mechanical connecting device has the beneficial effects that the structure is simple, and a damping piece is arranged at the bottom of the round floor so that noise can be effectively lowered and vibration can be reduced; direct contact between the components is avoided, friction is reduced, and the service life of the device is prolonged; and running safety of the device is improved through a protective fence, and popularization is easy.
