Problems solved by technology

[0006] In order to overcome the shortcomings of the complex technical structure of the above-mentioned radial bogie, the bogie of the present invention adopts the wheel set self-guiding radial principle. The connecting device connects the wheel sets, and through the coupling effect of the front and rear wheel sets when passing the curve, the wheels are in a radial position when passing the curve

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Such as Figure 1-11 As shown, the present invention includes a welding frame 2, a braking device 3, a wheel pair 1 and a wheel pair connecting device 4, wherein the wheel pair 1 is connected to the wheel pair connecting device 4, and a welding frame is arranged above the wheel pair connecting device 4 2. The braking device 3 is connected with the welding frame 2.

[0038] The welded frame 2 includes two side beams 7, a beam 8, a brake suspension rod 9 and a secondary damping device 10, a beam 8 is connected between the two measuring beams 7, and a beam 8 is connected between the beams 8. A secondary damping device 10 is provided below, and brake suspension rods 9 are provided on both sides of the beam 7 .

[0039] The brake hanger 9 is used to radially connect the two side beams 7 of the frame, and a brake hanger is provided on the brake hange...

Abstract

The invention particularly discloses a radial welding bogie with a low dynamic effect. The radial welding bogie comprises a welding framework, a braking device, a wheel set and a wheel set connecting device, wherein the wheel set is connected with the wheel set connecting device; the weld framework is arranged above the wheel set connecting device; and the braking device is connected with the welding framework together. The welding framework comprises two side beams, a cross beam, a braking boom and two vibration damping devices, wherein the cross beam is arranged between the two side beams; a vibration damping tray is arranged below the cross beam; and the braking boom is arranged at the two sides of the cross beam. Due to the adoption of the framework of a welding structure, the overall weight of the bogie is lightened; due to the fact that the effective connection is realized through the braking boom between the two side beams of the bogie, the overall anti-warp stiffness of the bogie is greatly improved, and the critical speed of the bogie is improved; and the low dynamic effect of the bogie is realized by elastic bearing saddles adopted by the bogie, so that the acting force between wheel-rails is reduced.

Description

technical field [0001] The invention relates to a low dynamic action radially welded bogie for railway freight car applications. Background technique [0002] The main freight car bogie currently in operation in my country is the Zhuan K6 bogie, which adopts a cast three-piece structure, a wedge-type friction damper, and a lower cross support device. The K6 bogie has good running performance in a straight line. Performance, but the wear on the wheels and tracks is severe when going through curves. [0003] The Zhuan K7 radial bogie, which was launched in China later, adopts a cast three-piece structure, a wheel set connecting device, and a wedge-type friction damper, which alleviates the wear problem of the wheels and rails when passing a curve, but due to the steering The frame bolsters and side frames are of cast construction, so the bogie is heavy. [0004] The above-mentioned bogies belong to the cast three-piece structure. Due to the self-heavy weight of the bogie and ...
