Problems solved by technology

However, the connecting rod of this patent can only be adjusted in length during installation or maintenance, and cannot realize real-time one-way follow-up adjustment of the connecting rod length, and cannot provide one-way anti-rolling moment
[0011] However, the above-mentioned patent is not the same as the technical solution of the present application, and the length of the connecting rod cannot be adjusted in one direction in real time, nor can it provide a one-way anti-rolling moment

Embodiment Construction

[0047] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings:

[0048] Adjustable torsion bar systems such as figure 1 As shown, it includes: a torsion bar 20, a left link 10 and a right link 30, the torsion bar 20 is fixed on the bogie / car body, and the two ends of the torsion bar 20 are hinged with one end of the left link 10 and the right link 30 respectively , the other ends of the left link 10 and the right link 30 are respectively hinged with both sides of the vehicle body / bogie. The left connecting rod 10 and the right connecting rod 30 are adjustable hydraulic connecting rods, and the length of the connecting rods can be switched between the states of maintaining the same, extending with one-way follow-up, or shortening with one-way follow-up, so that the torsion can be shortened. Rod systems provide two-way anti-roll moment or one-way anti-roll moment. In order to meet the safe driving re...

Abstract

The invention relates to an adjustable torsion bar system and an anti-side-rolling method, an adjustable hydraulic connecting rod is adopted to form the adjustable torsion bar system, and the characteristics of the hydraulic connecting rod are changed by controlling the flowing of a liquid medium, so that the length of the connecting rod has the characteristics that the length is kept unchanged, and the length is extended or shortened in a one-way follow-up manner. Therefore, the anti-side-rolling torsion bar system can provide two-way anti-side-rolling torque or one-way anti-side-rolling torque so as to meet the safe driving requirements of railway vehicles on different rails.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an adjustable torsion bar system and an anti-rolling method. Background technique [0002] With the continuous improvement of the running speed of the vehicle and the requirements for ride comfort, the existing vehicle suspension system is difficult to meet the safety and comfort requirements when the train passes through the curve at high speed. The pendulum train can make the car body tilt actively before the vehicle reaches the curve, and rely on its own gravity to balance the centrifugal force on the curve, so it can better solve the safety and comfort problems when passing the curve at high speed compared with traditional rail transit vehicles. [0003] Since the anti-roll torsion bar is used to prevent the rolling of the rail vehicle due to passing curves, strong winds and bumps, it ensures the driving safety. When the car body is actively tilted, the anti-roll torsi...
