What is the pull rod inside a car's steering gear
The internal tie rod of the automotive steering gear (i.e., the ball joint of the internal tie rod) is a component connected to the steering gear, mainly responsible for the precise control function of the steering system.
Specific functions
The inner tie rod ball joint is located inside the steering gear, directly connecting the steering wheel and the steering system. It is responsible for transmitting steering instructions and controlling steering accuracy. Its function is similar to the "wrist" of the steering wheel, achieving vehicle steering control through precise mechanical transmission.
Structural features
It is usually composed of precisely machined metal parts and needs to withstand frequent steering actions and vibration shocks to ensure the stability and reliability of the steering system.
The pull rod inside the automotive steering gear is a core component of the steering system and mainly undertakes the following functions:
Transmit steering torque
The pull rod inside the steering gear converts the movement of the steering rocker arm into the steering action of the steering knuckle arm, achieving precise control of the steering wheel over the steering of the wheels.
Ensure steering stability
The automatic clearance compensation is achieved through the ball joint pin connection structure, ensuring the stability and accuracy of the steering process and reducing the offset caused by road bumps during driving.
Withstand bidirectional loads
Made of special steel, it can withstand bidirectional tensile and compressive loads, ensuring the stable operation of the steering system under complex working conditions.
Maintenance Precautions
It is necessary to regularly check the swing force and rotational torque of the ball joint pin, and achieve forward toe-in calibration by adjusting the thread of the cross tie rod body to avoid a decrease in steering sensitivity or safety hazards due to wear.
A malfunction of the pull rod inside the car's steering gear can lead to problems such as steering failure, unstable vehicle body, and difficult operation of the steering wheel, which requires timely maintenance.
Common symptoms
Youdaoplaceholder0 Severe steering wheel vibration : When driving at medium speed or above, the steering wheel experiences periodic vibration, accompanied by chassis noise and vehicle body shaking.
Youdaoplaceholder0 deviation during driving : On arched roads or bumpy sections, the vehicle swings left and right and has difficulty maintaining a straight line.
Youdaoplaceholder0 brake deviation : when braking, the vehicle veers to one side and cannot stop in a straight line.
Youdaoplaceholder0 Tire anomaly : The tires show signs of shaking, bouncing or swaying at low speeds.
Youdaoplaceholder0 Steering wheel sticking : When turning the steering wheel, there is a lag, delayed return to the original position, or uneven force when turning left and right.
Cause of malfunction
Youdaoplaceholder0 tie rod breakage or loosening : This leads to loss of control over wheel movement and causes instability of the vehicle body.
Youdaoplaceholder0 Wear of the ball joint or insufficient lubrication : causes steering jamming and abnormal noise.
Youdaoplaceholder0 Dust cover damage : It may cause water to enter the steering gear and lubrication failure.
Handling suggestions
Youdaoplaceholder0 Immediate inspection : If the above symptoms are found, it is necessary to go to a 4S store or a professional repair point for examination in a timely manner.
Youdaoplaceholder0 Replace the pull rod : disassemble and assemble the dust cover, ball head and other components as per the specifications. After replacement, four-wheel alignment is required.
Youdaoplaceholder0 Regular inspection : Pay attention to early signs such as abnormal noises from the steering system and abnormal steering wheel return.
The damage of the pull rod inside the car's steering gear can cause abnormal steering system, which is specifically manifested as the following symptoms:
Abnormal operation
Youdaoplaceholder0 Severe vibration of the steering wheel : When driving at medium speed or above, the steering wheel experiences periodic vibration. In severe cases, it may cause the driver's cabin and car doors to shake.
Youdaoplaceholder0 Decreased steering sensitivity : steering becomes clumsy, and at low speeds, the wheels may bounce, sway or tremble.
Youdaoplaceholder0 deviation : When braking or driving, the vehicle automatically veers to one side. You need to hold the steering wheel firmly to keep the vehicle moving in a straight line.
"Safety hazard"
Youdaoplaceholder0 Abnormal noise : A "clunk" sound may be heard when driving at low speed. In severe cases, it may cause the ball joint to fall off, resulting in steering failure.
Youdaoplaceholder0 Tire wear : In the long term, it will cause the wheels to wear out unevenly, increasing maintenance costs and safety hazards.
Maintenance suggestions
When replacing, it is necessary to confirm that the model of the parts matches. It is recommended to operate at a professional repair point to ensure safety.
After replacement, four-wheel alignment calibration is required to avoid problems such as tire biting.
If the above symptoms are found, timely maintenance should be carried out to avoid potential safety hazards.
