Embodiment 1

[0025] A rail vehicle with a torsion bar radial mechanism can be installed such as figure 1 The radial mechanism shown achieves the self-guiding function of the bogie.

[0026] The torsion bar type radial mechanism includes 5 main parts: tension and compression bar 51 , pivot arm 52 , torsion bar 53 , front misaligned tension and compression bar 54 , and rear misaligned tension and compression bar 55 .

[0027] The tension and compression rod 51, the pivoting arm 52, and the axle box 3 are hinged, and the pivoting arm 52 and the torsion bar 53 are connected through a shaft hole to constrain the degree of freedom of rotation and axial displacement. The dislocation tension and compression rod 55 is connected with the torsion bar 53 through the rotating arm 52 on the other side of the frame 1 .

[0028] The front dislocation tension and compression rod 54 is mainly composed of two parts: a straight rod part 541 and a dislocation rod part 542 . The rear dislocation tension and c...

Embodiment 2

[0036] A rail vehicle, which adopts the above-mentioned torsion bar radial mechanism, the difference is that the two ends of the tension and compression bar 51 are respectively connected with the running part 7 and the rotating arm 52 using ball joints, and the rotating arm 52 and the torsion bar 53 are connected by shaft holes , the torsion bar 53 is installed on the vehicle body through two bearings, and the dislocation type tension and compression rods 54, 55 avoid their respective movement spaces by using the dislocation parts.

Abstract

The invention discloses a torsion rod type radial mechanism, a steering frame and a vehicle. The torsion rod type radial mechanism comprises a front dislocation pulling and pressing rod, a rear dislocation pulling and pressing rod, a front pulling and pressing rod, a rear pulling and pressing rod, a front torsion rod, a rear torsion rod and four rotating arms; the front end of the front pulling and pressing rod is connected with a front right axle box, the rear end of the front pulling and pressing rod is in hinged connection with the lower end of the second rotating arm, and the top end of the second rotating arm is in hinged connection with the right end of the front torsion rod; the rear end of the rear pulling and pressing rod is connected with a rear right axle box, the front end of the rear pulling and pressing rod is in hinged connection with the lower end of the third rotating arm, and the top end of the fourth rotating arm is in hinged connection with the right end of the rear torsion rod; the front end of the front dislocation pulling and pressing rod is connected with a front left axle box, the rear end of the front dislocation pulling and pressing rod is in hinged connection with a rear left axle box, and the top end of the third rotating arm is in hinged connection with the lower end of the first rotating arm, and the top end of the first rotating arm is in hinged connection with the left end of the front torsion rod. The radial mechanism disclosed by the invention can realize a radial function.

Description

technical field [0001] The invention relates to a torsion bar type radial mechanism, a bogie and a vehicle, belonging to the field of rail transportation. Background technique [0002] In the field of rail transit, wheel-rail wear has always been an important issue in the rail transit industry. Using a reasonable radial device can reduce wheel-rail wear, improve wheel-rail adhesion, improve curve passing, reduce the risk of derailment and reduce wheel-rail noise. Designing a radial mechanism with simple structure, high reliability, availability, maintainability and safety has always been a difficult problem in the industry. Chinese utility model patent CN200920297803.2 discloses a radial bogie torsion bar self-guiding mechanism, which provides a simple structure design, but its rocker arm is not easy to fix. Contents of the invention [0003] The present invention aims to provide a torsion bar radial mechanism, a bogie, and a vehicle. The radial mechanism can realize the ...
