Problems solved by technology

In addition, because the weight of each car is different, the inertia of each car is different. When the car brakes suddenly, the heavy car will squeeze the front car, causing it to derail and cause a greater safety accident.

Abstract

The invention discloses braking device capable of effectively reducing derailment of a high-speed emergency brake train. The device comprises an arc-shaped pipe mounted on the inner wall of a bottom cavity of a carriage, and a swing arm rotationally connected to the axle. The swing arm is rotationally connected with a transmission shaft. A speed reducing wheel is rotationally connected to the transmission shaft. A deformation cavity is formed in the speed reducing wheel. An annular cavity is formed in the circumferential inner wall of the deformation cavity in a penetrating manner. A cross hydraulic system is arranged in the deformation cavity. According to the invention, a group of arc-shaped sliding speed reducing wheels taking the axle as the circle center are arranged on the original axle, a friction plate which is originally distributed in a rhombus shape can be changed into a triangle through the change of the oil quantity in the speed reducing wheel, and the longest triangular edge makes contact with the rail. On the basis of original tangent point friction contact, surface contact friction is increased, friction force is increased, and the speed reduction effect is improved. Meanwhile, a limiting structure abutting against the bottom end of the rail is arranged on the structure making contact with the rail, and the probability of carriage derailment is reduced.

Description

technical field [0001] The invention relates to the technical field of train braking, in particular to a braking device that can effectively reduce the derailment of high-speed sudden braking trains. Background technique [0002] With the continuous maturity of railway construction technology, the speed of all trains except Gaote has been greatly increased. However, during the high-speed operation of the train, when an unexpected situation requires sudden braking, the traditional braking equipment locks the wheels of the train, and then restricts the movement of the train through the friction between the wheels and the rails. [0003] But, because the wheel is a circular structure, the frictional contact position between the wheel and the rail is a tangent point, and the frictional resistance that can be provided during sudden braking is small. In addition, because the weight in each car is different, the inertia of each car is different. When the brakes are sudden, the hea...
