Wiper linkage: an important part of ensuring driving safety
The structure and working principle of the wiper linkage mechanism
The wiper linkage mechanism is usually composed of connecting rod, pendulum rod and brush holder. In the electric wiper, the rotating motion of the DC motor is transmitted to the connecting rod through the worm gear mechanism, and the connecting rod then drives the swing rod and the brush holder to swing, so as to achieve the wiper scraping function.
Second, the replacement and maintenance of wiper linkage precautions
1. When replacing the wiper motor, the entire linkage mechanism needs to be replaced at the same time to ensure that the wiper can work normally. Because the motor damage often leads to some parts of the linkage mechanism are also damaged, such as the joint of the linkage arm falls off.
2. The way the support rod of the wiper is connected to the wiper rocker arm is also an important factor affecting the working effect of the wiper. If the support rod is not connected accurately, it will lead to problems such as unclean wiper scraping or abnormal sound. Therefore, when replacing the wiper or repairing the wiper, it is necessary to pay attention to check whether the support rod connection is accurate and make the necessary adjustments.
3. In the process of use, if the wiper is found to have poor wiper effect or abnormal sound and other problems, it is necessary to check the status of the linkage mechanism in time, and make necessary replacement or adjustment.
In short, the wiper linkage mechanism is an important part of the car wiper, and its normal work is of great significance to ensure the driver's driving safety. When replacing or maintaining the wiper, it is necessary to check the status of the linkage mechanism and make necessary replacement or adjustment.
What are the components of the car wiper system? What is the role of each part?
An automobile wiper system mainly consists of the following components:
Motor: provides power source, is the core component in the wiper system.
Rotating rod: connected motor and scraper arm, transfer power.
Wiper arm: fixed wiper blade, the other end is connected with the wiper connecting rod.
Scraper: direct contact with glass, to remove rain, snow and dust, to ensure a good view.
Reducer: reduce motor speed, increase torque, make the wiper blade work at an appropriate speed and strength.
Four connecting rod mechanism: to help the wiper arm to move on the glass, to achieve the reciprocating motion of the wiper blade.
Wiper arm mandrel: supports and secures wiper arm.
Sprinkler motor: control wiper spray water, clean glass.
Switch: In the cab, the owner can select the gear he needs by flicking the switch, such as intermittent, slow, fast.
Boneless wiper blade, wiper rubber strip, wiper sheath and plastic parts: these parts constitute boneless wiper blade, the support is stainless steel, steel sheet is carbon steel, the length of 10-28 inches, the thickness of 0.80~0.90 mm, the width is generally 7.00~14.00 mm. The elasticity of boneless wiper blade is better than that of general bone wiper blade, can reduce jitter wear, in addition to its uniform force, sun protection, simple structure, lighter weight and other characteristics 12.
Together, these components ensure that the wiper system effectively removes rain, snow or dust from the windshield and provides the driver with a clear view.
