Embodiment Construction

[0010] Now take Figure 1 as an example to illustrate the specific implementation process.

[0011] In order to integrate the advantages of the traditional wheel set and the independent wheel set and overcome their shortcomings, the left and right wheels of the coupled wheel set are neither completely consolidated nor completely independent. For the magneto-rheologically coupled wheelset, the left and right wheels are coupled to an appropriate degree through the magneto-rheological coupler, so as to obtain better dynamic performance of the magneto-rheologically coupled wheelset vehicle. As shown in Figure 1: the left wheel is not only connected to the axle shaft through a tapered roller bearing, but also connected to the left outer coupling disc through a coupling sleeve 16. In addition, the left and right outer coupling discs (6 is the right outer coupling disc) are made of cast aluminum The magnetic isolation ring 12 made of alloy is integrated with the magnetic isolation bol...

Abstract

The present invention relates to a controllable coupler of magnetorheological coupling wheel pair, belonging to the field of railway rolling stock technology (including urban guideway vehicle technology). It is characterized by that said invention utilizes the characteristics of magnetorheological coupling wheel pair which requires the magnetorheologic fluid to must have higher viscosity when the magnetic field is zero, it utilizes paste-like material or colloidal material with high viscosity as carrier, and utilizes permanent magnet whose surface is equipped with a circular groove to provide initial magnetic field so as to make the magnetorheological fluid always possess higher yield stress, so that said invention can make vehicle have good dynamic property.

Description

1. Technical field [0001] The technical field of the invention relates to railway locomotives including urban rail transit vehicles. 2. Background technology [0002] Due to the large longitudinal creep force, the traditional wheel set has the function of straight line centering and curve guidance, but the traditional vehicle is prone to snaking motion instability at high speed; the independent wheel set has no longitudinal creep force and loses the straight line The centering on the curve and the guiding ability on the curve lead to serious wear and tear on the wheel rim and rail side or even derailment. The advantage is that the critical speed of the snaking motion of the independent wheel set vehicle is infinite in theory. In recent years, due to the development of magnetorheological fluids (MRF) technology, in order to integrate the respective advantages of traditional wheelsets and independent wheelsets, Dr. Chi Maoru from Southwest Jiaotong University in my country fir...
