  • the movements of the doors installed with these mechanisms when the door is opened and closed are still dominated by rotation, and at the same time a certain translation is made. When the door is fully opened, the door still has a large lateral extension, and the mechanism is complicated, which affects the overall mechanism stability and is difficult to install.
  • the door of the passenger side of some buses also uses a four-link mechanism with two long and substantially equal turning links.-This mechanism makes the movement of the door basically dominated by translation. The door is placed after it is fully opened. Next to the door opening, it is close to the car body.

Therefore, all buses applying this technology place the fixed shaft of the auxiliary link on the underside of the car body floor. At the same time, the main link of the two rotating links also occupies Large body space.
