Traction connecting rod mechanism for railway vehicles and frame protection method

Abstract

The invention discloses a traction connecting rod mechanism for railway vehicles. A traction rod assembly, a power-assisted steering device and an overload protection device are arranged on an anti-roll bar assembly; one end of the traction rod assembly is connected with the anti-roll bar assembly; two ends of the power-assisted steering device and the overload protection device are respectively connected with one group of anti-roll bar assemblies. An oil pressure spring in an oil pressure spring assembly mounted between the two groups of anti-roll bar assemblies always provides tension outwards, and the turning power of the traction connecting rod mechanism can be increased, so that the vehicles are easy to turn; and moreover, the oil pressure spring is an elastic part and is capable of buffering acting force of the rails on a bogie while turning, so that the bogie can be well protected. A transverse casing in a transverse connecting rod assembly mounted between two groups of anti-roll bar assemblies can be automatically broken when a vehicle load is extremely high, so that the frame is prevented from being damaged.

Description

technical field [0001] The invention relates to a traction connection mechanism on a rail vehicle, in particular to a traction linkage mechanism and a frame protection method for a rail transit monorail vehicle. Background technique [0002] Urban rail transit has gradually become the first choice for people to travel due to its obvious advantages of convenience and speed, but its disadvantages are also obvious, that is, large investment, difficulty in line selection and construction, which promotes the popularity of monorail vehicles. Monorail vehicles have the advantages of small turning radius, strong climbing ability, and low operating noise. To a certain extent, they overcome the difficulties of line selection and construction. Its application is becoming more and more extensive, and it has gradually become the mainstream urban rail transit mode. [0003] In rail vehicles bogies are used to support the car body and are used in the final assembly of the vehicle. The str...

Problems solved by technology

[0006] Although the patent with the application number CN201510915678.7 is also a traction linkage mechanism for rail transit monorail vehicles, there is no oil pressure spring assembly installed between the anti-roll bar components, and the traction linkage mechanism and the bogie will not be connected when the vehicle is turning. The force is rigid and cannot buffer the force between the track and the bogie well, so the bogie cannot be well protected

In addition, there is no protection device such as a transverse link assembly installed between the anti-roll bar assemblies, and the frame cannot be protected when the load of the vehicle is too large.
