As the saying goes, "Spring will not be sunny for three days." With the arrival of spring, rain begins to become frequent, and you must be unable to drive on rainy days without a wiper. According to the latest survey, more than two-thirds of traffic accidents in rainy days are caused by unclear vision in front of the vehicle. Therefore, it is very important to choose a good pair of wipers. However, many car owners don’t know much about wipers, let alone how to choose. What brand of wiper is good and how to choose wiper? With these questions, let’s enter today’s article together.
If you want to know which brand of wiper is good, you must first understand the definition of wiper.
What is a wiper
wiper refers to a piece structure installed in front of the windshield, which consists of a motor, reducer, four-link mechanism, wiper arm mandrel, wiper blade assembly, etc. The main function is to remove rain, snow and dust on the windshield that hinders vision.
wiper classification
1, traditional intermittent
This is the most common wiper, ranging from three to four segments, and the driver makes adjustments according to the rain and sight conditions.
2, raindrop induction type
raindrop induction type is mostly used on medium and high-end models.
Wiper Working Principle
The power source of the wiper comes from the motor, which is the core of the entire wiper system. The motor uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear and worm mechanical part. The function of the worm gear and worm mechanism is to reduce speed and increase torque. Its output shaft drives the four-link mechanism, and the continuous rotational movement is changed into a left-right swing motion through the four-link mechanism.
wiper motor adopts a 3-brush structure to facilitate speed change. The interval time is controlled by the interval relay , and the motor's return switch contact and the charge and discharge functions of the relay resistor capacitor make the wiper wiper wiper sweep in a certain period of time. The wiper blade strip is a tool to directly remove rainwater and dirt from the glass. The scraper strip is pressed against the glass surface through the spring strip, and its lip must be consistent with the glass angle to achieve the required performance.
wiper is so important
The small wiper is not expensive, but it is closely related to safety. If it cannot wipe off the rainwater from the windshield, you will lose your safety as if you are driving blindly. When driving on rainy days, the traffic accident rate rate caused by unclear vision caused by the aging of wiper blades is much higher than usual. Therefore, the safety effect of wiper blades cannot be ignored.
Wipper usage method
1. Before heavy rain, check whether the car wiper can work normally.
2. On heavy rain, rapid and large raindrops hit the wind window glass. Even if the wiper moves faster, it is difficult to wipe away the raindrops, which affects the driver's vision. In order to ensure driving safety, stop driving immediately.
Wiper selection method
Good wipers must have the characteristics of heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, can fit the windshield, reduce the burden on the motor, low noise, strong water removal, soft quality and no scratching of the windshield, so that you can make your vision clear.
1. Choose
according to the model specifications first to figure out which wiper your car is using. You can refer to the manual to see the wiper model indicated above.
2. Whether the support rod and the rocker arm match
Pay attention to whether the way the support rod is connected to the wiper swinger arm matches. Because some support arms are fixed to the rocker arms with screws, while others are locked with convex buckles.
3. Check the rubber blade
Pull up the wiper, touch the cleaned rubber wiper with your fingers to check whether there is any damage and the elasticity of the rubber blades. If the blades age, harden and cracks appear, the wiper will not be qualified.
4. Wipe off at various speeds
During the test, place the wiper switch at various speed positions and check whether the wiper maintains a certain speed at different speeds. Especially in interrupted working conditions, you should also pay attention to whether the wiper maintains a certain speed during movement.
5. Check the wiper status
Check the wiper status and whether the wiper pole is unevenly swinging or missing. If the following three situations occur, it means that the wiper is unqualified. First, the swing is not smooth and the wiper is not jumping normally; second, the contact surface of the rubber cannot be fully fitted with the glass surface, resulting in wiping residue; third, the glass surface appears in a water film state after wiping, and fine stripes, fog and linear residues are generated on the glass.
6. Pay attention to whether there is abnormal noise in the motor
During the test, pay attention to whether there is abnormal noise in the motor, especially when the wiper motor "buzzes" and does not rotate. This means that there is a rust or stuck part of the wiper mechanical transmission part. At this time, the wiper switch should be turned off immediately to prevent the motor from burning.
7. The longer the better, the
Some people think that the longer the wiper blade, the larger the area of the brush, and the better the field of view. In fact, the longer the wiper blade, the better. Although extending the length of the wiper blade can increase the visible range of the field of view, it will also increase the burden on the wiper motor and wiper rod. Of course, it is OK to lengthen, but it is necessary to ensure that the wiper must not be hindered from the normal operation.
