Abstract
The present invention relates to railway train and tracks, especially pendulum train and tracks for high-speed railway. It features that the wheel for train has enlarged width and is conic with the outside and being smaller than the inside end. In the bend of railway, the seat of the outside track may be widened. The wide-wheel variable-radius pendulum train of the present invention needs no computer and complicated oscillation executing mechanism and is always in optimal balanced state through natural balance.
Description
The present invention relates to train and rail that railway transportation is used, relate in particular to required pendulum train of high speed railway and rail.
Traditional pendulum train is with the data input computing machine of whole road conditions and bend, again in the structure that designs many complexity between railway carriage and the wheel, when train passes through at a high speed from bend, computer moves according to factor command execution units such as radius of curve, speed per hours, make train appropriateness swing, to overcome train because the tendency of turning up that centnifugal force was produced.This structure precision is high, cost is high, also very easily goes wrong.At present, states such as the U.S., Japan, France, Britain, Germany and Italy all try to be the first and develop various pendulum trains, but all complex structure, cost are very high.
The objective of the invention is to want to design the most simple and practical a kind of pendulum train.
Purpose of the present invention can be achieved by following scheme, it is characterized in that: the wheel of widening train; And wheel made little, the inboard big cone shape in the outside; The railway outer rail at bend place can be widened the base in the outer rail outside.
The structure and the running condition of wide-wheel variable-radius pendulum train are described with figure now, and as shown in Figure 1: when train during at linear running, rail is in the wide centre of taking turns of train.As shown in Figure 2, when train is turned left, certainly lead to skid force to the right, the wheel on the right can be climbed naturally, and the wheel on the left side can glide naturally, the radius that is equivalent to left and right wheels this moment is changing, and train is tilted to the left naturally, has overcome train very naturally because the tendency of turning up that centnifugal force produced.As shown in Figure 3, when train bent to right, train also can be tilted to the right naturally, to overcome the tendency of turning up.As shown in Figure 4, when train is run at high speed, will inevitably produce bigger lateral pressure on bend, when lateral pressure is excessive, can widen the base in the outer rail outside outer rail.
The wide-wheel variable-radius pendulum train that the present invention is designed does not need computer and complicated vacillating actuator mechanism, so cost is extremely low, and the reliability height, its amplitude of fluctuation forms fully naturally, is in the optimum balance state all the time.
