10.11.1. Features of a design
The knot of a cleaner of a windscreen consists of a motor-reducer (the electric motor with a reducer), levers and brushes. The cleaner electric motor – with excitement from constant magnets, with two speeds of rotation. For protection of the electric motor against overloads in a cleaner the thermobimetallic safety lock is established.
The cleaner works in three modes:
The I mode – faltering, is provided to the electronic R1 relays established in the assembly block. This relay also includes a cleaner motor-reducer (small speed) at inclusion of a washer of a windscreen;
The II mode – constant, with small speed of movement of brushes;
The III mode – constant, with high speed of movement of brushes.
