Problems solved by technology

[0010] The above-mentioned patents are anti-nodding torsion bars developed for the nodding vibration of monorail trains. The torsion bars need to be installed on fixed supports. The installation position and installation method are limited by the fixed supports, and the required installation space is relatively large.

Embodiment 1

[0037] Example 1, such as Figures 6 to 9 Shown: an anti-rolling torsion bar device without a fixed support seat, including: a torsion bar assembly 1 and two sets of connecting rod assemblies 2, the torsion bar assembly 1 includes: a torsion bar 11 and two torsion arms 12, the The torsion bar 11 is a long bar, and the two ends are fixedly connected with the torsion arm 12 to form a U shape. The torsion bar and the torsion arm can adopt cylindrical interference fit, conical interference fit, or spur spline transition fit. , Straight tooth spline interference fit or bevel tooth spline interference fit and other methods of connection. A joint 13 is provided at the end of the torsion arm 12 away from the torsion bar 11 ; the connecting rod assembly 2 is a dumbbell-shaped bar with a joint 2 22 at one end and a joint 1 3 at the other end. An interface three 14 is also provided on the torsion arm 12 close to the end fixedly connected with the torsion bar 11, the joint one 3 of the c...

Embodiment 2

[0041] Example 2, such as Figures 10 to 11 As shown: the first joint is simply supported joint 4 , and the third interface 14 is a Y-shaped bump fixedly connected to the torsion arm 12 , and the Y-shaped bump is provided with a bolt hole for installing the simply supported joint 4 . The simply supported joint has the advantages of simple structure, large bearing capacity and easy installation.

[0042] The simply supported joint 4 is installed in the first interface 13 , and the simply supported joint 4 is installed in the second interface 22 . The simply supported joint 4 has the advantages of simple structure, large bearing capacity and easy installation.

[0043] The simply supported joint 4 is a short shaft, the two ends of the short shaft are flat square heads 41, and the surface of the flat square head 41 is provided with bolt holes 42 for being installed on the car body M or the bogie N; The middle part of the short axis is a cylindrical protrusion 43 .

Abstract

The invention provides a side-rolling resistance torsion bar device without a fixing supporting seat. The device comprises a torsion rod assembly and two connecting rod assemblies. Joints connecting with the connecting rod assemblies are arranged on a torsion arm to allow the connecting assemblies to hinge to the torsion arm so as to eliminate a normally arranged fixing supporting seat of a traditional torsion rod assembly, so that the demands on the installing space of the torsion rod is greatly reduced, the number of spare parts is reduced, the weight of the side-rolling resistant torsion rod device is reduced, and the designing degree-of-freedom of a rail vehicle steering frame is improved. The invention further relates to the rail vehicle adopting the side-rolling resistant torsion rod device without the fixing supporting seat, the rail vehicle has the advantages that the space between the body and the steering frame is small and the ground plate is low, and the device is particularly suitable for urban rail vehicles.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to an anti-rolling torsion bar device without a fixed support seat and a rail vehicle. Background technique [0002] Due to the characteristics of small vertical stiffness and large equivalent deflection, air springs are very suitable for the development of secondary suspension of rail vehicles, and have been increasingly widely used in recent years. However, due to the small vertical stiffness of the air spring, the roll angle of the vehicle will increase during the operation of the vehicle, resulting in a small roll stiffness of the vehicle, and even the phenomenon of roll instability, resulting in a decrease in the safety and smooth running performance of the vehicle. It is necessary to increase the roll stiffness of the vehicle separately to limit its roll angle, so as to improve the roll performance of the vehicle, but at the same time, it cannot affect the vi...
