Modular door drive
A drive device for a sliding door or a pivot and slide door of a transportation vehicle including at least one runner mounter such that it can at least move linearly so as to move a door leaf attached to the latter. A motor is attached to the runner of to the transportation vehicle. A first transmission mechanism between the motor and the runner affects the longitudinal displacement of the runner. Between the motor and the first transmission mechanism at least two attachment options are provided which differ in the arrangement relationship of the first transmission mechanism and the motor.
1. A drive device for a sliding door, or a pivot-and-slide door, of a passenger transportation vehicle, the drive device comprising:
at least one runner mounted such that it can at least move linearly so as to move a door leaf attached to the latter,
a motor attached to the runner or to the passenger transportation vehicle, and
a first transmission mechanism between the motor and runner so as to affect at least the longitudinal displacement of the runner, wherein between the motor and the first transmission mechanism at least two attachment options are provided, which differ in the arrangement relationship of the first transmission mechanism and the motor;
a supporting structure on which the at least two attachment options for the motor are provided;
wherein a first attachment option of the at least two attachment options defines a first arrangement relationship where a drive shaft of the motor is arranged coaxially with an input shaft of the first transmission mechanism; and
wherein a second attachment option of the at least two attachment options defines a second arrangement relationship where the drive shaft of the motor is arranged in parallel with the input shaft of the first transmission mechanism.
2. The drive device in accordance with the claim 1 , wherein a belt transmission is provided between the axis or shaft and the drive shaft of the motor.
3. The drive device in accordance with claim 1 , wherein the first transmission mechanism has a spindle transmission with at least one spindle nut in each case attached to the runner, and a spindle.
4. The drive device in accordance with claim 1 , wherein a coupling is provided between the first transmission mechanism and the motor.
5. The drive device in accordance with claim 1 , wherein a locking mechanism is provided for purposes of locking and unlocking the door leaf, and a second transmission mechanism is provided between the motor and the locking mechanism so as to affect the locking and/or unlocking action by means of the motor.
6. The drive device in accordance with the claim 5 , wherein the second transmission mechanism comprises a lever mechanism.
7. The drive device in accordance with claim 5 , wherein the motor is mounted such that it has a pivotal or rotary movement capability, and a rotary or pivotal movement of the motor is affected in the event of restraint or jamming of the first transmission mechanism and/or a change of drive direction of the motor, which movement by means of the second transmission mechanism is transferred onto the locking mechanism so as to affect the locking and/or unlocking of the door leaf.
8. An entry/exit facility for a passenger transport vehicle, including the drive device in accordance with claim 1 , and with at least one door leaf.
9. A passenger transport vehicle, including an entry/exit facility in accordance with claim 8 .
10. The drive device in accordance with claim 6 , wherein the motor is mounted such that it has a pivotal or rotary movement capability, and a rotary or pivotal movement of the motor is affected in the event of restraint or jamming of the first transmission mechanism and/or a change of drive direction of the motor , which movement by means of the second transmission mechanism is transferred onto the locking mechanism so as to effect the locking and/or unlocking of the door leaf.
