What is the pull rod inside a car's steering gear
The pull rod inside the car's steering gear is a key component of the steering system, mainly responsible for transmitting steering instructions and coordinating the movement of the wheels.
Core function
Youdaoplaceholder0 instruction passes
When the driver turns the steering wheel, the steering gear converts the steering command into the wheel steering action through the pull rod. Pull the left pull rod backward and push the right pull rod forward to create a steering Angle for the wheels.
Youdaoplaceholder0 motor coordination
The tie rods and the cross tie rods work in coordination to ensure that the left and right wheels are linked in a precise geometric relationship, maintaining the consistency of the track length changes during turns.
Youdaoplaceholder0 dynamic stability
Enhance the vehicle's cornering stability through mechanical structures (such as anti-roll reinforcement, suspension geometric locking, etc.) and absorb high-frequency vibrations ranging from 50 to 120Hz.
Component characteristics
Youdaoplaceholder0 structure : It is usually connected to the steering gear and wheels by a ball joint structure, achieving 50% torque transmission redundancy and ensuring steering accuracy.
Youdaoplaceholder0 Maintenance : Regularly check the tightness of the ball joint and the sealing of the dust cover to prevent the steering wheel from deviating or making abnormal noises due to wear.
The internal tie rod of a car's steering gear (usually referring to the steering straight tie rod) is a core component of the steering system. Its main function is to convert the rotation of the steering wheel into the steering action of the wheels, ensuring precise control.
Analysis of Specific Functions
Youdaoplaceholder0 steering command transmission
One end of the straight tie rod is connected to the steering gear pull arm, and the other end is connected to the steering knuckle. It converts the rotational action of the steering wheel into push-pull force, directly driving the front wheels to deflect. Its structural strength and stability directly affect the steering response speed and handling accuracy.
Youdaoplaceholder0 motion coordination control
When driving on bumpy roads or making sharp turns, the straight tie rods need to withstand repeated tensile and compressive stresses to ensure that the wheels move along the predetermined trajectory. If the components age or the clearance is too large (for example, the ball joint clearance exceeds 0.8mm), it will cause problems such as blurred steering and abnormal noise.
Youdaoplaceholder0 System stability
High-quality straight tie rods are made of alloy materials and feature stress stripe fatigue warning characteristics, which can reduce the force on hard points by 40% and extend the service life of the suspension system. Meanwhile, its dual ball head structure provides 50% torque transmission redundancy, enhancing safety.
It is recommended to check the ball joint clearance and bushing condition of the straight tie rod every 40,000 kilometers to avoid a decline in handling performance due to wear.
The main manifestations of faults in the internal pull rod of a car's steering gear are misalignment of the steering wheel, vehicle deviation, unresponsive steering or abnormal noises, etc. Timely maintenance is required to ensure driving safety.
Common fault manifestations
Youdaoplaceholder0 The steering wheel needs to be tilted to keep the vehicle moving in a straight line : The steering wheel needs to be deliberately adjusted in Angle to keep the vehicle moving in a straight line, mostly due to improper installation of the inner tie rod or failure to perform four-wheel alignment.
Youdaoplaceholder0 Abnormal steering : including heavy steering wheel, stuck steering, slow return speed or uneven force in left and right steering, which may be accompanied by abnormal noise.
Youdaoplaceholder0 Vehicle body instability : The vehicle swings left and right during driving, especially on bumpy roads.
Youdaoplaceholder0 Abnormal noise : The suspension system makes a clicking sound, which may be related to the wear of the connecting parts of the inner tie rod.
Cause of malfunction
Youdaoplaceholder0 Component aging : Long-term use leads to wear of the ball joint of the steering tie rod, loosening of the nut or bending of the inner tie rod.
Youdaoplaceholder0 Installation issue : Incorrect installation or failure to perform four-wheel alignment during maintenance, resulting in wheel alignment deviation.
Youdaoplaceholder0 External factors : Collision, corrosion or insufficient lubrication may also cause damage to the internal pull rod structure.
Handling suggestions
It is recommended to contact a professional maintenance institution for inspection first
Shake the ball head of the inner pull rod to test the looseness
Check if the nuts are loose or rusted
Replace damaged parts and perform four-wheel alignment if necessary.
