What does the inward pull bar do?
The in-direction pull bar and the straight pull bar play an important role in the automotive steering system. They are responsible for directing the power and motion transmitted by the steering rocker arm to the steering ladder arm or the steering knuckle arm. Because these ties withstand the double action of tension and pressure in the work, it is necessary to use high-quality special steel to manufacture, so as to ensure the stability and reliability of their work. As the core component of the automobile steering system, the steering rod is closely combined with the automobile front shock absorber. In different types of steering gear, the connection of the steering tie rod will be different, for example, in the rack and gear steering gear, it will be connected to the rack end, and in the circulating ball steering machine, it is connected to the regulating tube to adjust the distance between the ball joints. The steering tie rod, including the steering straight tie rod and the steering cross tie rod, has a direct impact on the steering stability, driving safety and the service life of the tire. The straight pull rod is connected to the pull arm of the steering motor and the left arm of the steering knuckle, which is responsible for transmitting the steering motor power to control the wheel; The tie bar connects the left and right steering arms to ensure synchronous movement of the two wheels and can be used to adjust the front beam.
What is the action of the pull rod ball head in the direction machine?
The pull rod ball head in the steering system realizes the function of swinging up and down by combining with the rack, and further drives the pull rod with the shell of the ball head, so as to help the car achieve more rapid and smooth steering action.
In the automobile steering system, the pull rod ball head plays a vital role. It connects the ball head of the steering spindle and the ball head housing, and realizes flexible steering operation through the precise articulating of the ball head seat at the front end of the ball head and the edge of the shaft hole of the ball head housing. The needle roller is cleverly embedded in the hole groove of the ball head seat to enhance the stability and durability of the structure.
Does it matter if the pull rod inside the steering machine is broken
There are
If the pull rod in the steering machine is broken, it will have the following effects :
steering wheel return function weakened or disappeared : if the pull rod in the steering machine is damaged, the steering wheel return speed may be too slow or completely unable to return, affecting the stability and safety of driving.
unstable driving : The damaged inner pull rod will cause the vehicle to shake left and right during driving, and even deviate from the driving track, especially when driving on bumpy roads.
brake deviation : damage to the inner pull rod may also lead to deviation of the vehicle when braking, increasing the difficulty of driving and safety risks.
direction failure : when the inner pull rod is seriously damaged, it may lead to direction failure, and the car can not turn normally, which poses a great threat to the safety of the driver and passengers.
Prevention and maintenance recommendations :
regular check : regularly check the status of the tie rod in the steering machine, including the fastening and wear of the connection, to find and solve the problem in time.
maintenance : Perform maintenance according to the schedule recommended by the manufacturer to ensure that all parts are in good condition.
avoid external impact : avoid severe impact and vibration during driving to reduce the damage to the pull rod in the steering machine.
Timely replacement of damaged parts : Once you find signs of damage to the pull rod in the steering machine, it should be replaced in time to avoid safety hazards.
The pull rod in the steering machine has a gap shaking abnormal sound
The reasons for the abnormal noise caused by the gap shaking of the tie rod in the steering machine may include the following:
Aging or wear of steering tie rod ball head : Aging or wear of steering tie rod ball head will cause clearance, which will cause abnormal noise. In this case, it is necessary to replace the steering tie rod ball head and carry out four-wheel positioning.
Oil leakage from the dust jacket of the steering gear : Oil leakage from the dust jacket of the steering gear may cause insufficient lubrication, increase friction and wear, and produce abnormal noise. The solution is to replace the dust jacket or re-butter.
internal parts of the steering machine are worn or loose : the gear, rack, bearing and other parts of the steering machine are worn or loose, which will also cause abnormal sound. In this case, these parts need to be inspected and replaced regularly.
improper tightness or aging of the booster belt : improper tightness or aging of the booster belt will also lead to abnormal sound. Need to adjust the belt tightness or replace the belt.
The methods to solve the abnormal sound of the pull rod in the steering machine with a gap include:
Replace steering tie rod ball head : If the steering tie rod ball head is aged or worn, it needs to be replaced with a new ball head and four-wheel positioning.
Adjust the internal parts of the steering machine : if the internal parts of the steering machine are worn or loose, you can try to adjust the screw press rack to reduce the amount of loosening.
Replace the dust jacket or make new butter : If the dust jacket leaks oil, replace the dust jacket or make new butter.
Adjust or replace booster belt : If the booster belt tightness is improper or aging, you need to adjust the belt tightness or replace the belt.
Through the above method, can effectively solve the problem of the pull rod in the direction machine has a gap shake abnormal sound, to ensure the safety and stability of the vehicle.
