A turnout for increasing train lateral passing speed

Abstract

The invention provides a turnout for increasing the lateral passing speed of a train. A turnout system comprises a curved strand and a straight strand. The curved strand comprises an inner rail and an outer rail. The horizontal elevation of the outer rail is not changed, the radius of the lead curve of the turnout is not changed, but the horizontal height of the inner rail of the curved strand of the turnout is reduced. The turnout has the beneficial effects that on the premise that the radius of the lead curve of the turnout and the plane geometrical characteristic and the length of the turnout are not changed, the speed of the train laterally passing through the turnout is increased, or at the same passing speed, the centrifugal force generated when the train laterally passes through the turnout is reduced, the stability and comfort of lateral turnout passing of the train are improved, the wheel rail acting force acting through the train on the turnout is reduced to some extent, the structural reliability of the part is enhanced, maintenance and serving of the turnout are reduced, the service life of the turnout is prolonged, and the safety and reliability of turnout running and passing of the train are improved.

Description

technical field [0001] The invention relates to a railway turnout, in particular to a turnout for increasing the lateral passing speed of a train. Background technique [0002] A turnout is an equipment facility that guides a train to enter or cross another line. Commonly used turnouts are ordinary single-opening turnouts. The way a train passes through an ordinary turnout can be divided into straight passage and lateral passage. When a train passes straight through a turnout, the train It runs on a straight line, and when the train passes the turnout sideways, the train runs on a curve. According to the principle of mechanics, when a vehicle passes a curve, a certain centrifugal force will be generated in the train vehicle, and its magnitude is related to the radius of the curve and the speed of passing the curve, as shown in the following formula: [0003] [0004] It can be seen from formula (1) that under a certain curve radius, the higher the speed of the train pass...

AI Technical Summary

Problems solved by technology

Increasing the radius of the lateral curve not only greatly increases the manufacturing cost of the turnout, but also significantly increases the length and floor space of the turnout, which brings difficulties to the design and construction
