Causes of Common Faults of Wiper Assembly and Countermeasures

We know that the wiper assembly is a complete set of products including wiper blades, wiper arms and wiper appliances. According to relevant data, the failure of the wiper assembly is mainly caused by the wiper motor, which is mainly divided into five types. They are water ingress inside the motor, rusting of the gear shaft, overload burnt, gear picking and deformation of the brush holder. Today, let's talk about the countermeasures against the failure of the wiper motor.

Water ingress into the motor of the wiper assembly is one of the most frequent faults of the wiper motor, and the water ingress in the general motor will directly cause the function of the wiper motor to fail. The main reason is that the sealing ring fails or the design of the sealing groove and the sealing ring is unreasonable. In response to this failure, the wire diameter of the rubber o-ring can be appropriately increased or plastic with high sealing performance can be used as the material of the gasket.

There are generally two reasons for overloading and burning. One is that the wiper motor shaft is overheated and burned due to the overload operation of the wiper assembly. For the first type of failure, wiper motor manufacturers generally choose to install motor overload protection measures or heat-resistant treatment of the main shaft. The second kind of failure is generally caused by the material of the main shaft is not rust-resistant, and it can be properly replaced with a rust-resistant and waterproof material to manufacture the wiper motor shaft of the wiper assembly.
