Example Embodiment
[0037] Example 1, as Figures 6 to 9 Shown: an anti-roll 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, so The torsion bar 11 is a long bar, and both ends are fixedly connected to the torsion arm 12 to form a U shape. The torsion bar and the torsion arm can adopt cylindrical interference fit, conical interference fit, and straight tooth spline transition fit. , straight tooth spline interference fit or bevel tooth spline interference fit etc. One end of the torsion arm 12 away from the torsion bar 11 is provided with an interface one 13 ; the connecting rod assembly 2 is a dumbbell-shaped rod, one end is provided with an interface two 22 , and the other end is provided with a joint one 3 . An interface 3 14 is also provided on the torsion arm 12 close to the end fixedly connected with the torsion bar 11 , and the joi...
Example Embodiment
[0041] Example 2, as Figures 10 to 11 Shown: the first joint is a simply supported joint 4 , and the third interface 14 is a Y-shaped bump fixed 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 simple structure, large bearing capacity and easy installation.
[0042] A simply supported joint 4 is installed in the first interface 13 , and a simply supported joint 4 is installed in the second interface 22 . The simply supported joint 4 is simple in structure, large in bearing capacity and easy in installation.
[0043] The simply supported joint 4 is a short shaft, and both 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 mounting on the vehicle body M or the bogie N; The middle of the short axis is a cylindrical protrusion 43 .
[0044] The simply supported joint 4 is a metal simply supported joi...
