The specific embodiment

One embodiment of the present of invention are described with reference to the accompanying drawings.

The unidirectional control car door of bus Fig. 1 comprises: a door hurdle (2) of going up rotation in rotating shaft (1), determine door hurdle off position and prevent that the hurdle from turning over this position-reversed and opening by door hurdle stop screw (3), door hurdle return torsion spring (4) makes a hurdle SELF CL, unidirectional the closing on the single direction ratchet device control gate hurdle of forming by ratchet (6) and ratchet gear ring (7), drg (8) is fixing by fix screw (11) and rotating shaft (1), control is unlocked and locks in the door hurdle when having the passenger to get on and off, and the door hurdle can only be closed and can not be opened when no passenger got on and off.Rotating shaft (1) is by being installed on the doorframe of car door at support fix screw (10) and rotary shaft rack (9).

Unidirectional control car door principle of work: bus is in operational process, and the car door of bus is generally closed by driver's control, and this moment, the upper and lower car door of unidirectional control car door also was closed.

The exit door of unidirectional control car door, the control passenger can't get on the bus from exit door, adopts car door place's pedal sensor (15) control normally engaged brake (8) and ratchet device.After bus arrives at a station, the exit door of passenger vehicle is opened in driver's control, this moment is if no passenger gets off, exit door place pedal sensor (15) does not have signal, drg (8) is normally closed, and locking ratchet gear ring (7) is because ratchet device can only make a hurdle (2) rotate towards closing direction, door hurdle this moment (2) is closed, so the passenger can't get on the bus from unidirectional control exit door under the car.If Che Shangyou passenger will get off, the passenger is through exit door place's pedal sensor (15), sensor provides a signal, drg (8) unclamps, because ratchet gear ring (7) sky is enclosed within the rotating shaft (1), door hurdle (2) overcomes return torsion spring (4) under the effect of passenger's propelling thrust torsion is opened, and the passenger gets off.This moment is if no passenger continues to get off, pedal upper sensor (15) does not have signal, to making drg (8) closure, make ratchet gear ring (7) by locking, this moment door hurdle (2) transfers back to hurdle stop screw (a 3) position in the effect of return torsion spring (4) through ratchet device and closes.Because ratchet device can only rotate towards closing direction, ratchet gear ring (7) is by locking, and the passenger under the car can't draw back or spur a hurdle, and the passenger is reverse under the control car gets on the bus.If continue to have the passenger to get off, the circulation said process.After the passenger gets off and finishes, driver's closed door that travels, cut off the signal (no matter whether stand the people) of pedal upper sensor (15), drg (8) is normally closed braking mode, locking ratchet gear ring (7), door hurdle return torsion spring (4) makes a hurdle (2) be in limit off position, so unidirectional control car door is closed locked.

The entrance door of unidirectional control car door, the control passenger can't get off from entrance door, adopts car door place's pedal sensor (15), normally disengaged brake (8) and ratchet device (ratchet is reverse).After bus arrived at a station, the driver opened entrance door, breakaway braking device control signal simultaneously, and drg (8) unclamps, and ratchet gear ring (7) sky is enclosed within the rotating shaft (1), and a door hurdle is in free state, and the door that the passenger promotes unidirectional control entrance door under the car blocks (2) and gets on the bus.If there is the passenger to want from getting off by this entrance door, when the passenger during by entrance door place pedal sensor (15) sensor provide a signal, make drg (8) closure, locking ratchet gear ring (7), this moment, a door hurdle can only be closed under the effect of return torsion spring.Because the escapement unidirectional action, the passenger on the car gets off at the hurdle (2) that can't pull the door open, and push away a hurdle (2) is closed, and the reverse passenger that historical facts or anecdotes is now controlled the entrance door place gets off.Driver's closed door that travels, drg (8) closure signal of giving the entrance door of unidirectional control car door, locking ratchet gear ring (7), door hurdle (2) is locked at off position.
