Embodiment Construction
[0049] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.
[0050] An anti-rolling device for a rail transit vehicle bogie, such as figure 2 As shown, the anti-rolling device is mainly composed of tension and compression bar 1, swing arm 2, first torsion bar 3-1, second torsion bar 3-2, third torsion bar 3-3, bevel gear sets A, B, C, D and so on.
[0051] One end of the tension and compression rod 1 is connected to the bogie through a ball joint, and the other end is connected to one end of the swing arm 2 throu...

The invention discloses an anti-side-rolling device used for a rail transit vehicle bogie and a method for obtaining the anti-side-rolling stiffness. The anti-side-rolling device comprises a pair of pulling and pressing rods arranged at intervals, a pair of torsion arms arranged at intervals, and first torsion rods; one end of each pulling and pressing rod is hinged to the end of the torsion arm, and the other end of each pulling and pressing rod is used for being connected with an vehicle body or a bogie in a hinged mode. The anti-side-rolling device is structurally characterized in that the two first torsion rods are coaxially arranged at intervals, each first torsion rod is connected with the other ends of the torsion arms; the two first torsion rods are connected with a third torsion rod through a corresponding transmission mechanism, wherein the third torsion rod is arranged at one side of the first torsion rod, and all torsion rods are used for being installed on the bogie. According to the anti-side-rolling device used for the rail transit vehicle bogie and the method for obtaining the anti-side-rolling stiffness, the torsion rod of the traditional anti-side-rolling device is creatively divided into a plurality of segments from one section, equipment can be installed in a polygonal region which is composed of the multiple torsion rods at will, and interference is avoided.
Description
technical field [0001] The invention relates to an anti-rolling device for a rail transit vehicle bogie and a method for obtaining anti-rolling stiffness, which belong to the structural design of bogie components. Background technique [0002] The main function of the anti-roll device is to rely on the torsional deformation of the torsion bar to limit the roll angle of the car body, while keeping the ups and downs of the car body unaffected. [0003] The torsion bar of the currently used anti-rolling device is a whole section, which is unfavorable for the installation arrangement of the equipment on the bogie and the car body. And when the torsion bar is a whole section, the anti-roll stiffness of the anti-roll device can only be adjusted by modifying the structural size of the anti-roll device or the material of the torsion bar. [0004] Chinese invention patent application CN201210403416.9 discloses an anti-roll torsion bar assembly device for rail vehicles. The anti-rol...
