Embodiment Construction

[0014] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0015] combine Figure 1~3 , The bogie of the present invention mainly comprises a wheel set device 1, a bolster 2, a side frame 4, a cross support device 3 and a damping device 5. Wherein the damping device 5 is a friction shock absorber, which is made up of a combination wedge and a pillow spring device.

[0016] In order to improve the anti-diamond stiffness of the three-piece bogie, the cross support device 2 is arranged symmetrically on both sides of the bolster 3, wherein the center of gravity of the cross support device 2 and the center of gravity of the two side frames 4 are on the same plane.

[0017] like figure 2 , Two groups of cross support devices are made up of an elastic joint I and two cross bars 5,6. Bar 6 directly passes through the intersecting hole reserved by bar 5 at the intersection position, and bar 5 and bar 6 are connected by elastic...

Abstract

The invention aims to provide a wagon bogie. The wagon bogie comprises wheel pair devices arranged at front and rear sides, side beams positioned at two left and right sides, a swing bolster positioned between the two side beams and damping devices mounted on the side beams; two crossing support devices are arranged between the two side beams and are positioned at two sides of the swing bolster respectively; the crossing support devices comprise two crossing rods; four end parts of the two rods are provided with an elastic joint respectively; the elastic joints are connected with the side beams; and the elastic joints are in threaded connection with the rods. The wagon bogie can improve the rhombus-resistant rigidity, enables a train system to be higher in the critical speed and stronger in stability, and can improve the adaptive capacity of the bogie for anti-torsion and unsmooth conditions.

Description

technical field [0001] The invention relates to a train, in particular to a train bogie. Background technique [0002] The three-piece bogie is mainly composed of a wheel-to-axle box device, a side frame and a bolster. , resulting in a rhomboid deformation easily occurring between the two side frames, resulting in a low critical speed and poor stability of the vehicle. Therefore, an elastic cross tie rod device is added at the bottom of the bolster to increase the anti-rhombic deformation stiffness of the bogie, thereby increasing the critical speed of the system. [0003] However, adding an elastic cross tie rod device at the bottom can improve the ability of the bogie to resist rhomboid deformation. Higher bogies are very urgent and necessary. Contents of the invention [0004] The object of the present invention is to provide a railway freight car bogie which can improve the anti-diamond stiffness of the three-piece bogie. [0005] The purpose of the present inventi...
