Headlight cleaner
Consists of two (left and right execution) gearmotors with levers and brushes. Thermal bimetallic fuses are installed in the gearmotors to protect against overloads. Motorized headlight cleaners are available in a non-separable design. Therefore, they cannot be repaired and, in case of failure, must be replaced with new ones.
The headlight cleaner has a number of double strokes of the gearmotor shaft at a torque load of 0.05 kgf-m, a supply voltage of 12 V and an ambient temperature (25±10) °C should be 45-60 per minute, and the current consumption should not exceed 1.5 A.
Rear window cleaner
It consists of a motor reducer, a lever and a brush. The motor reducer is equipped with a thermal bimetal fuse for protection against overloads. The design of the geared motor allows it to be disassembled to eliminate minor malfunctions (collector cleaning, etc.). The disassembly and assembly methods are the same as those described above for the windshield wiper gearmotor.
At the rear window cleaner with a gearmotor load of 0.05 kgf-m, a supply voltage of 14 V and an ambient temperature (25±10) °C the number of double strokes of the gearmotor shaft must be (50±5) per minute, and the current consumption is not more than 2 A.
