Analysis of Guidance Performance of Track Vehicle with Mechanical Differential Coupled Wheelset

At present,symmetrical differential is widely used in rotary wheel-rail vehicles.The device of differential control between left and right wheels has become a hot issue in current research.On the basis of dynamics,the influence of mechanical differential coupling wheelset on running vehicles is analyzed by a model,which includes rigid wheels and independently rotating wheels.Through the model analysis,the steering performance of mechanical differential coupling wheelset in straight line and curve is studied.It is found that the wheels rotating independently of the mechanical differential coupling device have a positive impact on the wheel alignment in the reset,and have a good solution to the poor steering ability of the independent wheels.Compared with rigid wheels,mechanical differential has better safety and guidance performance in passing performance.It has a good application in the field of urban rail transit.By discussing the principle of wheel steering,this paper studies the influence of mechanical differential coupling device on the steering performance of rail transit vehicles.
