Auxiliary brake mode generator for motor train unit

Abstract

The invention relates to the field of mechanical braking, in particular to an auxiliary brake mode generator for a motor train unit, which comprises an SBT and an ASBT, wherein the output end of the SBT is connected with the input end of the ASBT, the SBT includes a step-up transformer, a first ceramic resistor, a second ceramic resistor, a first wiring terminal board, a first mounting bend angle, a second mounting bend angle, a third mounting bend angle, a first mounting plate and a second mounting plate, the ASBT includes a step-down transformer, wire-wound resistors, adjustable ceramic resistors, diodes, a rectifier bridge, non inductive capacitors, electrolytic capacitors, a second wiring terminal board, a fourth mounting bend angle, a third mounting plate, a mounting baseplate and a fifth mounting bend angle. The auxiliary brake mode generator has the advantages that the structure is simple, both the SBT and the ASBT can be installed on the vehicle only by four bolts, disassembly and assembly are convenient, the auxiliary brake mode generator adopts a fully analog linear circuit, has no low voltage control loop, does not generate electromagnetic interference signals, are not subjected to external electromagnetic interference, is stable and reliable, and provides a guarantee for the emergency braking of the motor train unit.

Description

technical field [0001] The invention relates to the field of mechanical braking, in particular to an auxiliary braking pattern generator for multiple train sets. Background technique [0002] my country's high-speed railway EMUs have been developed since 2006. Through technology introduction, joint design, digestion and absorption, and re-innovation, major achievements have been made. During the high-speed operation of the train, there may be some special situations that require emergency braking of the train. Emergency braking will cause a lot of damage to the commonly used braking mode, and sometimes it will directly cause the failure of the commonly used braking mode. The faulty EMU is sent back to the depot for troubleshooting. At this time, a safe and reliable auxiliary braking system is needed. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a safe and reliable auxiliary braking pattern ...
