Abstract

The invention relates to a vehicle locking device having a mechanical rotary connection between a cylinder core of a lock cylinder and a lever system of an associated lock and comprises a driver coupling having two sleeve bodies which are mounted coaxially to one another and, in their installed position, are positively coupled to one another with the interposition of a rotary lost motion freewheeling connection. The rotary movement of the sleeve body drivable by the cylinder core, via a rotary connection element, is sensed for the purpose of controlling an additional locking function superposed on the rotation of the cylinder core. The other sleeve body is dynamically coupled to a securing element of the lever system of the lock. In order to achieve a substantial freedom in the arrangement of the control elements, the two sleeve bodies are rotatably connected to one another and are independently rotatably mounted on a support, spaced from the lock cylinder. The rotary drive from the cylinder core is connected only to the primarily drivable sleeve body.
