Problems solved by technology

[0005] For a two-point supported vehicle, the anti-roll torsion bar has a relatively high rigidity. If other tilting methods are used, the anti-roll torsion bar will generate a large moment resistance, hindering the vehicle body from tilting, causing the actuator to be larger or even exceed the The maximum limit value of bearing capacity and strength of other components

Abstract

The invention discloses an active tilting device which comprises a first adjustable connecting rod, a second adjustable connecting rod, a first torsion arm, a second torsion arm, a first torsion bar, a second torsion bar, a first flange, a second flange, a third flange, a speed reducer, a motor and an outer sleeve support. The input end of the speed reducer is connected with the motor through the third flange, the outer sleeve support is connected to the shell of the speed reducer, and the motor is arranged in the outer sleeve support. The first flange is connected to the output end of the speed reducer, one end of the first torsion bar is in interference fit with the first flange, and the other end is in interference fit with the first torsion arm; the first adjustable connecting rod is in spherical hinge connection with the first torsion arm; the second flange is fixedly connected with the outer sleeve support, one end of the second torsion bar is in interference fit with the second flange, and the other end is in interference fit with the second torsion arm; and the second adjustable connecting rod is in spherical hinge connection with the second torsion arm.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an active tilting device. Background technique [0002] High speed and comfort are the development trend of rail vehicles. However, due to the limitation of line conditions, such as the large number of curve segments and many small radius curves, simply increasing the running speed of the vehicle will increase the unbalanced centrifugal force of the vehicle during the turning process, which will affect passengers. The comfort and the safety and stability of the vehicle. Considering the high cost of building high-speed railways, high maintenance costs, and high technical requirements, it is expected that the vehicles on the existing lines will be transformed so as to achieve the purpose of increasing the running speed of the vehicles. [0003] Tilting train is an effective technical measure to increase the speed of existing lines. The working principle is as follows: ...
