9.12. Screen wipers

Features of a design
The complete set of a cleaner of a windscreen consists of a drive of a cleaner, levers and brushes.

Fig. 9.21. The scheme of inclusion of a cleaner and a windscreen washer: 1 – the electric motor of a washer of a windscreen; 2 – the electric motor of a cleaner of a windscreen; 3 – the switch of a cleaner and a windscreen washer; 4 – the assembly block; 5 – the ignition switch; And – to power supplies; К2 – the relay of a cleaner of a windscreen; К6 – the additional relay


The scheme of inclusion of a cleaner is shown on fig. 9.21. The cleaner has three operating modes.
I mode – faltering. This mode is provided with electronic relay K2 of type 524.3747 or 523.3747, established in the assembly block. This relay also includes a cleaner motor-reducer (small speed) at inclusion of a washer of a windscreen.
II mode – constant, with small speed of movement of brushes.
III mode – constant, with high speed of movement of brushes.
The scheme of connections of conclusions of the relay of a cleaner of a windscreen is shown on fig. 9.21.
The relay should provide inclusion of the electric motor of a cleaner with frequency 14±4 a cycle in a minute in a range of work from idling (loading only draughts) to loading the maximum effective moment 3,92 Н·м (0,4 кгс·м) at frequency of rotation of a shaft of a motor-reducer not less than 20 mines-1, at temperature (20±5) °С and pressure of a food (14±0,2) Century
Data for motor-reducer check
Frequency of rotation of a shaft of a motor-reducer at pressure of a food 13,5 In, the moment of loading 2 Н·м and an ambient temperature (25+10) °С, mines-1:
First (small)....... 39–50
Second (big)....... 59–72
Consumed current strength at the moment of loading specified above, And, no more:
On the first speed....... 4
On the second speed....... 4,7

Fig. 9.22. The scheme of inclusion of a cleaner and a washer of back glass: 1 – the ignition switch; 2 – the assembly block; 3 – the switch of a cleaner and a washer of back glass; 4 – the electric motor of a washer of back glass; 5 – the electric motor of a cleaner of back glass; And – to power supplies; In – an order of conditional numbering of tips in колодке the electric motor; К6 – the additional relay


The cleaner of back glass consists of a motor-reducer, the lever and a brush. Packing of the lever with a brush right in the direction of the car. In motor-reducers of cleaners the thermobimetallic safety lock for protection against overloads is established. The scheme of inclusion of a cleaner of back glass is resulted on fig. 9.22.
At a cleaner of back glass at loading of a motor-reducer the moment 1 Н·м, pressure of a food 13,5 In, temperature (25±10) °С the number of double courses of a shaft of a motor-reducer should be in a faltering mode of 1618 mines-1, in constant 2030 mines-1, and a consumed current strength no more than 3 And.

Replacement of the relay of a screen wiper of a wind window
The scheme of connections of conclusions of the relay of a cleaner of a windscreen is shown on fig. 9.21.
The relay should provide switching of an operating mode of a cleaner for small speed at inclusion омывтеля a windscreen (if the cleaner worked on a faltering mode or has been switched off). After deenergizing of a washer of a windscreen the cleaner should make 2–4 full cycles of clearing on small speed at temperature (20±5) °С and pressure of a food (14±0,2) Century
