DRIVING SYSTEM FOR TURNED AND/OR DISPLACED DOORS OR FOR ENTRANCE/EXIT DEVICE WITH IMPROVED POSITION MEASUREMENT Russian patent published in 2011 - IPC E05F15/14 

FIELD: construction.

SUBSTANCE: driving system for an entrance/exit device, comprising at least one door installed with the possibility of rotation, a ramp or a step of a passenger vehicle, comprising at least one actuator or a driving motor (1, 24), a mechanism it actuates (3.3, 3.4) and/or a gear (2, 4, 26) with the purpose to cause door, ramp or step rotation movement, and also a sensor (7, 34) of absolute value for measurement of instantaneous position during the rotation movement and an assessment unit, which is designed for comparison of the instantaneous position with at least one reference position, which is stored in the nonvolatile memory of the assessment unit, in order to generate an output signal that depends on it, at the same time the absolute value sensor (7, 34) is flanged to a journal that sets the movement of door, ramp or step rotation, and the gear comprises the first step-down gearing (2), the second step-down gearing (4), and also a controlled engagement (3.3, 3.4) between step-down gearings (2, 4).

EFFECT: simplicity of position measurement adjustment.
