Abstract

The invention provides an automatically adjusting train magneto-rheological damper and relates to the technical field of rail traffic. The automatically adjusting train magneto-rheological damper comprises wheels. The two sides of the wheels are rotationally connected with damper bodies. The top ends of the damper bodies are fixedly connected with an installation plate. The installation plate is internally and fixedly connected with an insulating sleeve through a connection block. The insulating sleeve is internally and fixedly connected with a resistance coil. The front face and the rear faceof the insulating sleeve are both provided with sliding grooves. Springs are fixedly connected between the two ends of a sliding device and the inner wall of the installation plate. According to theautomatically adjusting train magneto-rheological damper, timely and rapid adjustment can be made according the borne pressure and a road condition environment, a damping and energy eliminating effectof the damper on a train when the train drives is improved, and when the train makes a turn and force borne by the wheels on the two sides is uneven, the stability of the train is improved.

Description

technical field

[0001] The invention relates to the technical field of rail transit, in particular to an autonomously adjustable magnetorheological damper for trains. Background technique

[0002] The damper is a device that provides movement resistance and consumes movement energy. Various dampers are used in aerospace, aviation, military, guns, automobiles and other industries to reduce vibration and energy dissipation. With the damper With the continuous development of technology, since the 1970s, people have gradually transferred these technologies to structural engineering such as buildings, bridges, and railways, and the damping shock absorber for trains is one of them.

[0003] However, what is installed on the traditional train is a spring damping shock absorber, and the damping force of the spring damping shock absorber will not change after installation, so that the train cannot change the damping force according to the passenger capacity and road condition informa...
