The invention relates to the technical field of travel braking of railway vehicles and discloses a regional and double-magnetic type permanent-magnet magnetic track braking device. The device comprises a fixed permanent magnetic mechanism, a rotary magnetic shaft and a brake device, wherein the rotary magnetic shaft is arranged in the fixed permanent magnetic mechanism, and a drive device drives the rotary magnetic shaft to rotate relative to the fixed permanent magnetic mechanism; first permanent magnet blocks distributed axially and uniformly are arranged in the rotary magnetic shaft; the fixed permanent magnetic mechanism comprises second permanent magnet blocks corresponding to the first permanent magnet blocks and two magnetic conduction plates arranged on two sides of the second permanent magnet blocks respectively, and magnetic poles of the first permanent magnet blocks and the second permanent magnet blocks are located on two side surfaces of the first permanent magnet blocks and the second permanent magnet blocks; the rotary magnet shaft and the fixed permanent magnetic mechanism are correspondingly divided into multiple regions along the axis, adjacent regions are connected in a magnetic isolation manner, the permanent magnet blocks in the same region have the same polarity direction, and the permanent magnet blocks in adjacent regions have the opposite polarity directions. The magnetic field direction is changed by driving the rotary magnetic shaft to rotate, and braking and relieving of the device and a rail are realized.
Description
technical field [0001] The invention relates to the technical field of rail vehicle brakes, in particular to a partitioned double-magnet permanent magnet rail brake device. Background technique [0002] With the acceleration of urbanization in our country, traffic problems such as urban traffic congestion, frequent accidents, and environmental pollution have increasingly become difficult problems for urban development. Urban rail transit has gradually become the mainstream of urban transportation development in my country due to its characteristics of large capacity, high speed and punctuality, saving space and energy. The brake device, one of the important components of the train, is used to decelerate the train so that the train can be stopped within a specified distance, ensuring the safety of the train and improving the passing capacity of the railway. [0003] For the braking methods of rail vehicles, according to the different transfer methods of train kinetic energy ...
