The lock consists of the housing ( 1 ), which is fastened on the bush ( 2 ) placed on the shaft ( 3 ) of the steering system, inside of which there is a sliding cylinder ( 4 ) with a coded key ( 5 ). In the cylinder ( 4 ) there is a keyway ( 14 ) in which there is peak of the pin ( 13 ) fastened in the housing ( 1 ). On the core ( 8 ) by the linchpin ( 16 ) a bush ( 15 ) is fastened, on which there is a ring eccentre ( 17 ) with the area ( 18 ). On the bush ( 15 ) there is placed a spiral spring ( 20 ). In the housing ( 1 ) along the eccentre ( 17 ) the pin ( 19 ) and the inductive switch ( 27 ) are placed. Inside the bush ( 15 ) the spiral spring ( 24 ) and the piston ( 25 ) are placed, while the peak of the piston ( 25 ) is fastened by the linchpin inside the piston ( 26 ) for locking. The free end of the piston ( 26 ) is placed in the keyway ( 28 ) of the bush ( 29 ) fastened in the shaft ( 3 ). In order to unlock, the core ( 8 ) is rotated and the cylinder ( 4 ) is axially moved. In the unlocked position the ring eccentre ( 17 ) is secured by pin ( 19 ) and activates switch ( 27 ). |
