DRIVE DEVICE FOR EMBARKATION AND DISEMBARKATION DEVICES OF PUBLIC TRANSPORTATION VEHICLES

摘要

The disclosure relates to a drive device for embarkation and disembarkation devices of public transportation vehicles, comprising a drive unit arranged within and drives a rotary column. The drive unit rotates the rotary column about the rotary column longitudinal axis Z-Z during opening and closing processes of the embarkation and disembarkation devices. The drive device is supported on the vehicle. The drive unit has a drive motor, a non-self-locking reduction gear, and a controllable blocking means with which a rotation of the rotary column can be blocked. The drive device further includes a sensor for detecting the magnitude of an external force, the force acting on the drive device. The drive device further has means for analyzing signals of the sensor and for triggering the blocking effect of the blocking means when an external force measured by the sensor exceeds a threshold.

主权项

1. A driving device for entering and exiting mechanisms of public transportation vehicles, comprising a drive unit arranged within a rotary column and drives this rotary column by rotating the rotary column about a longitudinal axis Z-Z during opening and closing operations of the entering and exiting mechanisms, wherein the driving device is held on the vehicle and the drive unit features a driving motor, a non-self-locking step-down gear and controllable blocking means, by means of which a rotation of the rotary column can be blocked,
wherein the driving device features a sensor, by means of which the magnitude of an external force acting upon the driving device can be measured, wherein the driving device furthermore features means for evaluating the signals of the sensor and for canceling the blocking effect of the blocking means when a limiting value for an external force measured by the sensor is exceeded.
