What is the car wiper linkage rod assembly
The car wiper linkage rod assembly is a mechanical transmission device that connects the wiper motor and the wiper arm. It is mainly used to convert the rotational motion of the motor into the reciprocating swing of the wiper arm, thereby cleaning the windshield.
Core function
Youdaoplaceholder0 Power transmission : Transfer the power from the wiper motor to the wiper arm to ensure the normal swing of the wiper.
Youdaoplaceholder0 Mechanical structure : It is usually composed of components such as connecting rods and swing arms, which are connected by hinges to form a transmission system.
Youdaoplaceholder0 Working principle : The motor drives the connecting rod to rotate, which in turn moves the wiper arm back and forth along the set trajectory, covering every area of the windshield.
Common applications
It is suitable for cleaning the front windshields of sedans, SUVs, MPVS and other models. Some models will also be equipped with rear Windows.
If the connecting rod is damaged (such as broken, deformed or loose connection), it will cause abnormal swing of the wiper and needs to be replaced in time.
The automotive wiper linkage rod assembly is the core transmission component of the wiper system, mainly achieving the following functions:
Power transmission
The rotational power of the wiper motor is increased in torque through the reducer and precisely transmitted to the wiper arm, driving it to perform reciprocating motion.
Synchronous control
Make sure that the left and right wiper arms are in absolute phase synchronization to avoid overlapping or missing cleaning areas.
"Motion conversion"
Convert rotational motion into oscillations of specific trajectories to meet the glass curvature requirements of different vehicle models.
Rigid support
Withstand the reverse impact force generated by the friction between the wiper blades and the glass to ensure transmission stability.
If the connecting rod is damaged (such as broken, deformed or loose connection), it will cause abnormal swing of the wiper, affecting driving safety. Therefore, regular inspection and maintenance are necessary to ensure that it is in good working condition.
A malfunction of the wiper linkage rod assembly may cause the wiper to fail to work properly. Common causes and solutions are as follows:
The transmission connecting rod is dislocated
This is one of the most common malfunctions. You can check whether the connecting rod is disengaged by opening the hood. If dislocation is detected, reinstalling and resetting will restore it.
The fuse has blown
Check whether the fuse corresponding to the wiper in the fuse box has blown. Before replacement, turn off the power.
Motor failure
If a motor problem is suspected, unplug the motor wire plug to measure the voltage. If the voltage is abnormal or accompanied by a burnt smell, the motor needs to be repaired or replaced.
Connecting rod connection failure
Check whether the connection points are loose, worn or broken. Repair or replace the components if necessary.
Problem with the wiper switch
Poor or damaged internal contact of the switch can cause signal transmission failure. The switch can be replaced after being detected with a multimeter.
Line fault
If the lines are aged, damaged or have poor contact, they need to be carefully inspected and repaired to ensure normal current transmission.
If you cannot solve the problem by yourself, it is recommended that you contact a professional for inspection and repair.
