Abstract

The invention discloses a deceleration device for rail transit. The device comprises a direct current motor whose bottom is provided with a machine base. The machine base is internally provided with astator iron core which is internally provided with a rotating shaft. Two ends of the rotating shaft are provided with bearings. The outer side of the rotating shaft is coated with a rotor iron core.Permanent magnets are evenly distributed on the outer side of the rotor core. The permanent magnets are coated by a rotor. A side face of the machine base is connected to a conductive wire whose another end is connected to a resistor box. A side face of the resistor box is provided with a plurality of resistors. Two opposite sides of the resistor box are provided with heat dissipation windows. Themachine base is internally provided with a circuit board whose surface is provided with a single-chip microcomputer, a sensor and a positioner. Before a train enters a station, the sensor and the positioner can transmit signals to the single-chip microcomputer, and the single-chip microcontroller transmits the signals to the direct current motor such that the direct current motor decelerates, andthus the train decelerates more precisely.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a deceleration device for rail transit. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, track There are more and more types of transportation, not only in long-distance land transportation, but also in urban public transportation with terminal distance. It has the advantages of safety, comfort, beauty and speed, which greatly facilitates people's travel . [0003] Due to the short distance between rail transit stations, the deceleration devices of rail transit operate more frequently. During the operation of urban planning trains, passengers get on and off frequently, which has a great impact on the decele...
