Abstract

This embodiment provides a car door and a rubber-tyred train. The car door includes two door columns, a door top beam, two first sealing bead and a second sealing bead; On the side of the door column, a plurality of first bead fixing holes are provided on the opposite side of the door column. The first bead fixing holes include the first bead adjusting part and the first bead fixing part connected to each other. The diameter of the first bead adjusting part is larger than that of the first bead adjusting part. The diameter of a fastener, the first fastener is clamped and fixed in the first bead fixing part; the second sealing bead is arranged on the side of the door top beam facing the door post, and the door top beam is provided on the side of the door post A plurality of second fixing holes, the second fixing holes include a second adjusting part and a second fixing part connected to each other, the diameter of the second adjusting part is larger than the diameter of the second fastener, and the second fastener is clamped and fixed on the second fastener. In the second fixed part. The vehicle door of this embodiment is beneficial to improving the installation efficiency of the staff for installing the sealing bead.

Description

technical field [0001] The present application relates to vehicle manufacturing technology, and in particular, to a vehicle door and a rubber-wheeled train. Background technique [0002] With the development of urban transportation construction, articulated trains (such as traditional low-floor trams, traditional trolleybuses, urban BRT trains, etc.) are gradually put into use to relieve road traffic pressure. An articulated train is a wheeled train composed of two or more carriages connected together by a hinge device. The articulated train changes its forward direction by the guidance of the hinge device between the carriages. [0003] On the train, the door is the main component of the car body, and since the door needs to be opened and closed frequently, its tightness is particularly important. In the solution of the related art, the door is provided with sealing strips which are respectively matched with the door pillar and the door top beam. However, the installation ...
