Abstract

The utility model discloses an improved two-sash passenger door opening/closing device for passenger cars. The device is mounted under the secondary step inside the passenger door of a passenger car; two opening/closing cylinders are connected to the vertical axis of the rack; the piston-rod of the cylinder is connected with a tire-rod connecting arm and a balance bar linking the rack and the passenger door. The passenger door opening/closing device is entirely arranged on the back surface of the passenger door; the device is capable to open and close the door easily, and the upper end and lower end of the door can be sealed easily. As a result, the tightness of the passenger door is ensured.

Description

The bus occupant door operating gear

Technical field

The utility model relates to a kind of start-stop system of bus passenger door.

Background technology

Existing passenger vehicle adopts the biparting passenger door of opening mostly in car, this passenger door is in opening process, passenger door will be crossed pivoted arm, pivoted arm can only be connected and installed in beyond the top and bottom of passenger door like this, and the gap that will leave rotation, cross, this just makes the sealing of passenger door upper and lower end very difficult, makes the bending of sealing hairbrush and adhesive tape, rubs and damage easily, influences the sealing and the use of passenger door.

Summary of the invention

The purpose of this utility model is exactly will provide a kind of can overcome the sealing difficulty of existing bus passenger door existence and the bus occupant door operating gear of sealing member rapid wear problem.

Be installed on below secondary is marked time in the bus passenger door for reaching goal of the invention design-calculated bus occupant door operating gear, be connected with two on the upright shafts on its frame and open and close cylinder, the piston rod of cylinder links to each other with the pull bar, connecting arm and the trammel beam that are connected frame and passenger door, and the bus passenger door top also has the door link arm to link to each other with rotating shaft with the interior support arm of car door upper ledge.

The start-stop system of the utility model bus passenger door places the back side of biparting passenger door fully, and the upper and lower end of not only conveniently opening and closing, and passenger door need not leave motion space, therefore is easy to sealing, makes sealing member not fragile.

Be the path of motion of Compensation Regulation passenger door, can Sealing shield ring and oscillating bearing be arranged in the rotating shaft of door link arm and arm room, make the keying of passenger door and sealing property even more ideal.
