Abstract

The invention discloses a rail gap sensor for a maglev train, which has three gap probes (7) and three acceleration sensors (8), and the three gap probes (7) and three acceleration sensors (8) are arranged along a strip The elongated grooves of the shaped mounting base (1) are installed on the mounting base (1) one by one, and the sealing cover (3) covering the gap probe (7) and the acceleration sensor (8) is fixed on the mounting base (1). The rail gap sensor has high precision, good reliability, high integration, small footprint, convenient installation and maintenance, and long service life.

Description

technical field [0001] The invention relates to a rail gap sensor in a suspension gap testing system of a maglev train. Background technique [0002] At present, there are three types of maglev trains successfully developed in the world: TR series (high speed) in Germany, MLX series (high speed) in Japan, and HSST series (low speed) in Japan. The most essential difference between all maglev trains and wheel-rail trains is that it has a suspension control system, thus enabling the train to run off the track. The track clearance sensor is an important part of the suspension control system. It is used to test the suspension clearance of the train relative to the track, and input the signal to the processor in the suspension chopper. The device changes the effective voltage applied to both ends of the suspension electromagnet to change the current of the suspension electromagnet, thereby adjusting the attraction force of the suspension electromagnet to the steel guide rail, so ...
