Embodiment Construction

[0030] Below by specific embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0031] Existing torsion bars such as figure 1 As shown: including: connecting rod 1, torsion bar 2 and support seat 3, torsion bar 2 is fixed on the bogie through support seat 3, and the two rotating arms of torsion bar 2 are respectively connected to the two sides of the car body through two connecting rods 1 When the car body is tilted, the connecting rods 1 on both sides of the car body respectively drive the two pivoting arms of the torsion bar 2 to rotate in the opposite direction, so that the torsion bar 2 is torsionally deformed, thereby producing an anti-side movement in the opposite direction to the car body tilt. The rolling moment is used to balance the gravitational moment generated after the car body is tilted, so as to ensure driving safety.

[0032] Since the centrifugal force of the train turning has a tendency to cause the car b...

Abstract

The invention relates to a method for actively adjusting the length of a connecting rod in real time. The length of the connecting rod can be actively adjusted in real time according to a control instruction by additionally arranging an active adjusting device on the connecting rod. Therefore, the defects that a traditional connecting rod is fixed in length and cannot be adjusted are overcome. Theactive anti-side-rolling torsion bar system comprises a connecting rod, a torsion bar and a supporting base, a ball screw mechanism is arranged on the connecting rod, and the length of the connectingrod can be rapidly adjusted in real time according to a control instruction, so that the torsion bar generates torsional deformation, and then anti-side-rolling torque is actively provided for a vehicle body; active adjustment of the side rolling angle of the train body is achieved, the speed and safety of the train passing through a curve can be improved, and therefore the running speed of the train is increased.

Description

technical field [0001] The invention belongs to the rail transit industry, and in particular relates to a method for actively adjusting the length of a connecting rod in real time and an active anti-rolling torsion bar system. Background technique [0002] When the train turns at high speed, the objects and passengers in the train will be affected by the centrifugal motion, which will cause the objects and luggage on the train to tilt and slide, and the passengers on the seats will also be pushed aside, and the standing passengers may lose their Balance and fall, so the train needs to reduce the speed when turning, which limits the speed of the train and restricts the capacity of the line. And adopt pendulum train can improve train turning speed, thereby improve the running speed of train. [0003] According to the different ways of tilting the car body, it can be divided into two types: natural pendulum and forced pendulum. Natural pendulum is also called passive pendulum...
