9.26. System of blocking of locks of doors
The system established on a part of release of cars, is intended for simultaneous lock-out of locks of all doors at lock-out of the lock of a door
of the driver by a key or by means of the button of blocking of the lock. At unlocking of the lock of a door
of the driver by the button or a key locks of all other doors also will be unblocked.
locks of back doors and the right forward door
separately is provided
by buttons of blocking of locks.
In each door
motor-reducers of drives of the locks, uniting in themselves the electric motor of a direct current with excitation from constant magnets and a reducer of type a gear wheel-rejka are established.
Fig. 9.26. The scheme of system of blocking of locks of doors: 1 – the assembly block;
2 – the management block; 3 – a motor-reducer of blocking of the lock of a door of the passenger; 4 – a motor-reducer of blocking of the lock of a back door;
5 – a motor-reducer of blocking of the lock of a door
The driver; And – to power supplies; In – the scheme of conditional numbering of tips in колодке
The management block; With – the scheme of conditional numbering of tips in колодках motor-reducers of blocking of locks
In a motor-reducer 5 (fig. 9.26
), established at doors
of the driver, is built in the switch which contacts are switched at moving of the button of blocking or at turn by a key of a drum of the lock of a door
At the closed contacts of the switch the electronic block of 2 managements includes all motor-reducers which through draughts block locks of doors. At disconnection of contacts locks will be unblocked by motor-reducers similarly.
In the management block there is the inertial switch providing an unblocking of doors at blow of the car about an obstacle during failure.
At malfunction of system check up a safety lock, wires and their connections, the block of management and motor-reducers. The block of management and motor-reducers not folding, and at failure replace them.
