Lock cylinder for vehicle; has control curve that rotates with cylinder guide when lock is forced, but rests against cylinder guide with radial projection when key is used to turn lock

摘要

The lock cylinder has a control curve arranged on the inner surface of a cylinder guide (13) with a radial projection projecting against the cylinder axis (39). The control curve rests against the casing when a key turns a rotor (30) in the lock cylinder but rotates with the cylinder guide when it is forced. A control component is fixed to the rotor so that it cannot rotate but can slide and rotates with the rotor when it is turned by a key or forced. A spring force is directed on a support position away from the cylinder axis. The support position is supported in a null position of the rotor by a maximum radial projection next to the cylinder axis and opposite an uncoupling position. When the key is turned, the support position is moved outside the null position of the radial projection into a larger radial spacing opposite the cylinder axis and takes up a coupling position against a carrier (60).
