7.14. Electroglass elevators of forward doors

Data for check of a motor-reducer



Electrowindow regulators for lowering and raising of glasses of forward doors complete a part of the released cars.
In the window regulator mechanism instead of the gear reducer applied in mechanical window regulators there is only a drum into which opening the output shaft of a motor-reducer is inserted.
The motor-reducer consists of a worm reducer and the electric motor of a direct current with excitement from permanent magnets. Its design is similar to a design of a motor-reducer of screenwash. A motor-reducer (reversive, the direction of rotation of an output shaft depends on the direction of current in an anchor winding. For protection against overloads it has the built-in thermobimetallic safety lock.

Схема включения электростеклоподъемников дверей
Fig. 7.31. Scheme of inclusion of electrowindow regulators of doors: 1 – assembly block; 2 – switch of an electrowindow regulator of the right forward door; 3 – motor-reducer of an electrowindow regulator of the right forward door; 4 – motor-reducer of an electrowindow regulator of the left forward door; 5 – switch of an electrowindow regulator of the left forward door; 6 – ignition switch; K5 – the relay of inclusion of electrowindow regulators; And — to power supplies; In — to the switch of external lighting

The scheme of inclusion of electrowindow regulators is provided on fig. 7.31. Motor-reducers 3 and 4 join the switches 2 and 5 located on handles of armrests. Supply voltage moves to switches at inclusion of ignition through the safety lock of F6 and the relay of electrowindow regulators K5 located in the assembly block 1.
If electrowindow regulators do not work, then it is necessary to remove upholsteries of doors and to check whether tension to motor-reducers moves, to check a safety lock and the relay of electrowindow regulators, to restore the broken connections in wires, to replace a faulty motor-reducer new.
