Wagon bogie framework and spring seat thereof

Abstract

The invention provides a wagon bogie framework and a spring seat thereof. The wagon bogie framework and the spring seat of the wagon bogie framework can reduce welding deformation and improve the locating precision for springs. The spring seat comprises a base plate and baffles, the base plate and the baffles are integrally formed in a casting mode, the baffles are arranged on the lower end face of the base plate annularly so that a cavity used for containing the springs can be defined by the base plate and the baffles together, and the bottom of the cavity is provided with an opening allowing the springs to stretch out. According to the spring seat, the base plate and the baffles are integrally formed in the casting mode, the baffles are arranged at the lower end of the base plate annularly in a surrounding mode, the cavity used for containing the springs is defined by the base plate and the baffles together, therefore, vertical locating and circumferential locating of the springs are respectively realized through the base plate and the baffles and locating of the springs is more reliable; more importantly, the whole spring seat is of an integrated structure through casting, compared with a spring seat formed through welding in the prior art, the spring seat has no weld seam, let alone the problem of welding deformation, therefore, the structural reliability of the spring seat is effectively guaranteed and the locating precision of the springs is improved.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to a spring seat of a railway freight car bogie frame. The invention also relates to a railway freight car bogie frame with the above-mentioned spring seat. Background technique [0002] At present, the frame adopted by the railway freight car bogie implements the traction and positioning of the wheelset through a series of suspension devices. The primary suspension device is usually a spring connected to a rotating arm, and the rotation of the rotating arm drives the wheelset to rotate. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an arrangement mode of the spring seat in the prior art. [0004] In order to realize the positioning of the spring, in the existing passenger car bogie frame, spring positioning parts are provided at the ends of the side beams on both sides of the frame, and the spring positioning part includes a ho...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that in the spring positioning parts in the prior art, there are welds in many parts such as the top and the outer peripheral wall, and more welds make the welding deformation difficult to control, which affects the positioning accuracy of the primary spring.

[0007] In addition, the welding seam between the spring positioning part and the vertical shock absorber seat 4' is relatively concentrated, which reduces the fatigue reliability of the frame
