Abstract
Description
technical field
[0001] The present invention relates to a plug-in door tooth belt dual-axis rocker guide bar groove-type cam combination space mechanism, which relates to a plug-in sealing opening and closing mechanism for an automatic door of a rail vehicle, in particular to a plug-in door for a high-speed rail or other rail vehicles. Toothed belt dual-axis rocker guide bar slot cam combined space mechanism. Background technique
[0002] At present, the automatic doors of rail vehicles at home and abroad mainly include three series of door systems: plug doors, external doors and built-in doors. The transmission methods mainly include screw transmission and toothed belt (ie synchronous toothed belt) transmission.
[0003] The sliding door system is usually a single or double door leaf. When it is a double leaf, on the one hand, it needs to realize the opening and closing movement of the two door leaves that are opened and closed. The door leaf plug moves inward to ensure a ...
