Abstract

The invention discloses a traction rod device of a railway express freight car bogie. The traction rod device comprises a traction rod body; a first mounting through hole is formed in one end of the traction rod body; a second mounting through hole is formed in the other end of the traction rod body; a first elastic spherical hinge is arranged in the first installation through hole in a penetrating mode, a second elastic spherical hinge is arranged in the second installation through hole in a penetrating mode, the first elastic spherical hinge is fixedly connected with the framework cross beamthrough a first installation base, and the second elastic spherical hinge is fixedly connected with the swing bolster through a second installation base. According to the traction pull rod device, the rubber elastic spherical hinges are arranged at the two ends of the traction pull rod body and are in rigid contact with the connecting parts of the framework and the swing bolster, no relative movement exists in the operation process, and the situations that fasteners are loosened and screw cracks occur in the operation process of a similar traditional passenger car bogie screw type traction pull rod device are avoided.

Description

technical field [0001] The invention relates to the technical field of a bogie pulling rod device, in particular to a bogie pulling rod device for railway express freight cars. Background technique [0002] At present, there are mainly two ways to transmit the longitudinal force of the railway freight car bogie. One is the integral frame bogie, the longitudinal force is directly transmitted from the center plate to the frame, and the other is the bogie with the bolster separated from the frame or side frame. The longitudinal force is first transmitted from the center plate to the bolster, and then transmitted to the frame or side frame through the bolster. However, due to the cancellation of the secondary frictional contact of the express truck bogie, a special structure is required to complete the transmission of the longitudinal force from the bolster to the frame. [0003] The transmission of the longitudinal force between the bogie bolster and the frame of a traditional...
