Problems solved by technology

The so-called short mechanism means that the length of the load-bearing drive mechanism does not exceed the opening of the door opening of the car body. For the mechanism with a single guide column slider structure, due to the length of the two sets of sliders plus the stroke of the door leaf and the guide column support, its The total length has exceeded the door opening of the car body by more than 200mm. If the double guide pillar structure is adopted, the length problem can be solved, but the structure is complicated, the weight is too heavy, and the dimensions in the other two directions are enlarged, which exceeds the capacity of the existing car body. space

Abstract

The invention discloses a bearing driving mechanism of a sliding door, which comprises a cylindrical rack, a door carrying rack component, a linear guide track, a slider and a door leaf component. The cylindrical rack is axially fixed, by the aid of double gear and rack transmission mechanisms, the door leaf component can further move horizontally in the same direction relative to the door carrying rack, so that opening stroke of a door leaf is increased on the premise of limited lengths of the mechanisms, and the bearing driving mechanism of the sliding door is simple in structure and light in weight, and can completely meet requirements of installation.

Description

[0001] technical field [0002] The invention belongs to the technical field of intercity rail transit door systems, and in particular relates to a load-carrying drive device in a sliding door system. Background technique [0003] The door leaf opening of the urban rail plug door is usually 1300mm and 1400mm, and the corresponding car body door opening is 1590mm and 1700mm. The so-called short mechanism means that the length of the load-bearing drive mechanism does not exceed the opening of the door opening of the car body. For the mechanism with a single guide column slider structure, due to the length of the two sets of sliders plus the stroke of the door leaf and the guide column support, its The total length has exceeded the door opening of the car body by more than 200mm. If the double guide pillar structure is adopted, the length problem can be solved, but the structure is complicated, the weight is too heavy, and the dimensions in the other two directions are enlarge...
