Abstract
Description
- A door actuated by a direct linear motor for public transport means, particularly rail vehicles.
- The invention deals with a sliding and push-out sliding doors actuated by a direct linear motor for public transport means, particularly rail vehicles.
- The sliding door wings slide into the walls or along the walls when opening. The wings may move on a linear or arched path. The mechanism is usually placed under a cover in the space over the door opening and the wings are suspended on that. The mechanism may also be placed behind the back edge of the wing where the wing moves to open. A guiding element with a shifting slider is the main part of the mechanism. The guiding element is attached on the fixed part of the vehicle body.
- Movement of the wings of the push-out sliding doors, where the wing first shifts to the front of the side wall and then slides linearly outside along the side wall away from the door opening, is provided by the door mechanism, which is usually located in the space over the door opening, and the wing is suspended on the mechanism.
- Both the sliding and the push-out sliding doors are equipped with an actuator unit for easier handling. The actuator unit may consist of a mechanical actuator unit or an electric actuator unit, according to the available energy source. The actuator units of electric door may be rotating geared electric motors or direct linear electric motors. A disadvantage of rotating electric motors is, that gearing mechanisms changing rotation movement to linear are necessary. Gearing mechanisms however have considerable friction, flexibility and slack, which reduce the life (increases wear) rigidity, dynamics and accuracy of movement.
- Direct linear electric motors remove the main disadvantage of geared rotating electric motors, the gearing.
- The aim of the invention is to solve compact actuation and a new generation mechanism opening sliding and push-out sliding doors of rail vehicles with a direct linear electric motor, while the actuator design has to meet the demanding criteria of safety and reliability and also has to show high degree of technical and technological level.
- The principle of the novelty of the sliding door actuated by a direct linear electric motor for public transport means, particularly for rail vehicles, is based on the fact that a holder of mechanism guide with a linear motor holder are attached to the vehicle body in the middle of the space over the door opening. A sliding door actuator is movably mounted to the mechanism guide holder, on which the sliding door wing itself is suspended. A linear motor rotor is a part of the sliding door actuator, for example in the form of an electronic aluminium sheet, which forms a rotor (slider) of the linear motor. End sensors controlling the end position of the door wings are mounted on the holder of the mechanism guide. There are also at least two stops mounted on the mechanism guide holder, fixing the door in the open or closed positions by positioning a tongue against the particular stop, while at least two tongues are arranged on the sliding door actuator.
- A cable guiding rod is also arranged on the mechanism guide holder. A holder with a sensor detecting people in the door opening is attached to the sliding door actuator.
- The principle of the novelty of the push-out sliding door actuated by a direct linear electric motor for public transport means, particularly for rail vehicles, is based on the fact that a mechanism frame is attached to the vehicle body in the middle of the space over the door opening. There is a holder attached to the frame through at least two balance beams. A linear electric motor and a carriage guided against the frame by a pulley in the shape of the guiding rail, are arranged on the holder. A linear motor rotor is a part of the slider, for example in the form of an electronic aluminium sheet (slider). The door wing is movably mounted to the holder by means of a traveller. The carriage is connected through the traveller with the door wing by 1 : 2 gearing.
- The enclosed drawings show the doors of public rail vehicles actuated by linear motor, while figures 1 and 2 present the sliding doors and the push-out sliding doors are in figures 3 and 4.
- Figures 1 and 2 show the sliding doors actuated by a linear motor designed for public rail vehicles. On the vehicle wall in the space over the door opening there is a
holder 2 of the mechanism guide with aholder 10 of thelinear motor 4. A slidingdoor actuator 3 with a sheet of electronic aluminium forming a rotor (slider) of thelinear motor 4, is movably attached to themechanism guide holder 2. The slidingdoor wing 1 is suspended on the slidingdoor actuator 3.Stops 5,end sensors 7 and acable guiding rod 9 are mounted at both ends of themechanism guide holder 2.Tongues 6 of thestops 5 and aholder 8 with a sensor of movement of people are attached to the slidingdoor actuator 3. - After switching the
linear motor 4 on the slidingdoor actuator 3 together with theslide door wing 1 start shifting on themechanism guide holder 2. End positions of the sliding door are detected by theend sensors 7. The sliding door is fixed in the open and closed positions by atongue 6 touching theflexible stop 5. Slide door opening may be initiated either by a button or automatically after detection of movement at the door by a sensor attached to theholder 8. - Figures 3 and 4 show push-out sliding doors actuated by a linear motor designed for public rail vehicles. A
frame 3 of the push-out sliding door controlling mechanism is mounted on the vehicle body over the door opening. Aholder 4 is fixed on theframe 3 of the push-out sliding door controlling mechanism via afront balance beam 5 and arear balance beam 6, which are arranged on ... Alinear motor 8 is attached and acarriage 7 movably arranged on theholder 4. Thecarriage 7 is guided against the controllingmechanism frame 3 on a pulley in ashaped rail 10. A sheet of electronic aluminium forming thelinear motor 8 rotor (slide) is a part of thecarriage 7. Thewing 1 of the push-out sliding door is movably attached with itsarm 2 by means of atraveller 9 on theholder 4. Thecarriage 7 is connected with the push-out slidingdoor wing 1 through atraveller 9 via gearing 1:2. - After switching the
linear motor 8 on thecarriage 7 starts shifting as against theholder 4. Thecarriage 7 is shifted in the guidingrail 10 in longitudinal as well as transversal directions in the first phase of the movement, by which thewhole holder 4 tilts closer to the side wall of the vehicle thanks to thefront balance beam 5 and therear balance beam 6. That will make thedoor wing 1 shift to the front of the side wall of the vehicle and in the next phase the door wing shifts along the shape of the guidingrail 10 along the vehicle side wall until it is fully open. Closing of the door happens in the opposite order. - The door is fully automatic with a microcomputer control.
- It is equipped with a non-contact safety sensors against squeezing on both sides.
- For better safety the actuator is equipped with a sensor signalling presence of people at the door.
- The front edge of the door wing is equipped with a contact ledge indicating a touch with an obstacle, as a safety element against squeezing.
- The actuator may be switched off by switches on both sides and the door may be opened and closed manually.
- The door is mechanically stabilized in the open and dosed positions. It may be locked in the dosed position.
- Force transfer between the actuating unit and the door wing is done by a gear element with proportion 1:2.
- Thanks to a completely new solution of location of the balance beams against the guiding element and the actuator unit attachment the invention ensures the maximum actuating power in closing.
- The door according to the invention in the sliding version is designed for interiors of public transport means, particularly rail vehicles. It may also be applied in buildings where extensive movement of people is expected.
- The door according to the invention in the push-out sliding version is designed as an entrance door of public transport means, particularly rail vehicles.
