Description

Interior Tilting Coach door drive mechanism

The utility model relates to the passenger vehicle door drive mechanism, refers to a kind of interior Tilting Coach door drive mechanism especially.

The passenger vehicle door is used maximum two kinds of forms that have at present, and a kind of is collapsible pneumatic passenger vehicle door, is used for low and middle-grade passenger vehicles more, is characterized in that transmission device is simple in structure, easy for installation, easily shakes when travelling, and noise is big, easily crushes the passenger at closing time; Another kind is an externally swing passenger vehicle door, is used for senior motorcoach more, particularly disposes the palace car of a/c system, and characteristics are that switch is steady, and noise is low, and sealing is tight, the transmission device complexity, and poor stability need have the existing field boundary debugging of senior technician, the cost height during assembling.

The purpose of this utility model be to provide a kind of in the Tilting Coach door drive mechanism, it is steady to have a switch door, noise is low, good seal performance is simple in structure, and is easy for installation, cost is low.

For reaching above-mentioned purpose, Tilting Coach door drive mechanism in of the present utility model, comprise the passenger vehicle door, guide rail, guide pins, on, following swing arm, rotating shaft, power arm etc., be characterized in being equipped with the passenger vehicle door of glass, be installed in the doorframe, the doorframe top is provided with guide rail, be provided with the guide rail tip in passenger vehicle door upper right side, rotating shaft by connection seat and bearing installation on the doorframe of passenger vehicle door one side, its upper end bends to certain angle according to windscreen inclination needs, can realize that windscreen has big leaning angle, the rotating shaft upper end connects a top link, and top link one end and passenger vehicle door top are hinged, the hinged swing arm once in rotating shaft lower end, one end of following swing arm and the passenger vehicle student hold hinged, and place, passenger vehicle door lower left is provided with a backing block in following swing arm, connect an adjusting bolt at the left lower end of visitor's door, make the stress point of passenger vehicle student side be following swing arm and backing block, the moment that acts in rotating shaft and the following swing arm is reduced greatly, the stability when having improved driving, an air pump is located at the passenger vehicle student and holds a side, one end of one power arm is connected with air pump, and end is connected with rotating shaft in addition.

The utility model has the advantages that:

1, simple in structure, Installation and Debugging are convenient;

2, because rotating shaft top has one to bend to certain leaning angle, removed the restriction that prior art is enclosed moulding before to passenger vehicle;

3, the passenger vehicle door is not shaken during running car.

Below in conjunction with accompanying drawing structure of the present utility model, technical characterictic are described further.

Accompanying drawing is a structural representation of the present utility model.

The drawing reference numeral explanation:

The 1-doorframe, 2-passenger vehicle door, the 3-guide rail tip, the 4-guide rail, the 5-top link, the 6-windscreen, the 7-rotating shaft, the 8-power arm, the 9-air pump, 10-regulates bolt, the 11-backing block, swing arm under the 12-, 13,14-connection seat and bearing,
