What are the front wiper blades of a car
The front wiper blades of a car are devices installed on the windshield to remove rainwater, snow water, dust and other debris. They are mainly composed of rubber strips, brackets and other components, and are driven by a motor to swing to keep the driving view clear.
Core function
It is used to remove rainwater from the windshield in rainy days, preventing obstructed driving vision and enhancing driving safety.
Structural composition
Youdaoplaceholder0 rubber strip : The wiping component that comes into direct contact with glass, which must have heat resistance and cold resistance.
Youdaoplaceholder0 bracket : A metal or plastic structure that connects the wiper arm to the rubber strip, and it is divided into boneless and boneless types.
Youdaoplaceholder0 drive system : It is converted into reciprocating motion by the motor through the connecting rod mechanism. Common types include electric and vacuum drive.
Type difference
Youdaoplaceholder0 bone wiper : The bracket has a main and auxiliary structure, which is suitable for complex environments and has high durability.
Youdaoplaceholder0 boneless wiper : Fits more closely with the curvature of the glass and is easy to disassemble and assemble.
Maintenance suggestions
Regularly check the wear condition of the rubber strips to avoid dry friction.
It is recommended to lift the wipers on snowy days or when exposed to intense sunlight to reduce the risk of aging or freezing.
The replacement cycle is generally 1 to 2 years or adjusted according to the degree of wear.
The front wiper blades of a car are mainly used to remove rainwater, snow and dust from the windshield, ensuring a clear driving view and enhancing driving safety.
Main functions
Youdaoplaceholder0 Remove obstacles : Quickly scrape off water droplets and snow from the windshield on rainy or snowy days to prevent visibility obstruction.
Youdaoplaceholder0 helps determine vehicle position : By observing the relative position between the starting point of the wiper and the curb, it can assist in determining the wheel trajectory and help avoid scratches when parking or driving.
Youdaoplaceholder0 is adaptable to various environments : heat-resistant, corrosion-resistant, and can maintain stable operation in harsh weather conditions (such as acid rain, intense sunlight) and complex road conditions.
Structural features
Made of rubber and combined with a metal/plastic frame, it features good elasticity and strong wear resistance, capable of withstanding frequent friction and extreme weather conditions.
The malfunction of the front wiper blades of a car may be caused by various reasons. Common faults and their solutions are as follows:
Common types of faults
Youdaoplaceholder0 wiper blade damaged
It is manifested as incomplete water scraping, cracks or hardening. New wiper blades need to be replaced. It is recommended to choose original or high-quality brand rubber strips to ensure the wiper effect.
Youdaoplaceholder0 The wiper arm is deformed or has uneven pressure
It may cause the wipers to jump or the water to be scraped unevenly. Ensure a tight fit with the glass by adjusting the Angle of the wiper arm or using a wrench to correct the deformed area.
Youdaoplaceholder0 the fuse blows
Open the hood to check the fuse box and replace it with a spare fuse of the same ampere to restore it.
Youdaoplaceholder0 the transmission connecting rod is disengaged
Manually check if the connection parts are loose, and re-fix the connecting rod joints to ensure smooth transmission.
Youdaoplaceholder0 motor fault
If the wipers do not move at all and the motor is overheating severely, check the voltage or use a multimeter to measure the resistance value. Replace the motor if necessary.
Troubleshooting steps
Youdaoplaceholder0 preliminary inspection
Open the hood and check if the fuse has blown.
Manually test whether the wiper arm is deformed or has excessive resistance.
Start the windshield wipers and listen for any abnormal sounds (such as the humming of the motor).
Youdaoplaceholder0 depth detection
Use a multimeter to measure the motor voltage and resistance value (the normal voltage range is 12-14V, and the resistance value needs to match the model specification).
Disassemble the motor to check for mechanical faults such as carbon brush wear and bearing jamming.
Youdaoplaceholder0 Emergency response
Replace the spare fuse temporarily or use tin foil as a temporary substitute (only in emergency situations).
Minor stains can be cleaned on the windshield with a glass cleaner.
If you cannot solve the problem by yourself, it is recommended to contact professional maintenance personnel for handling to avoid affecting driving safety.
