Automobile directional column ten-byte action
The automotive steering column plays a crucial role in the automobile. Its main functions include controlling the driving direction of the vehicle, transferring torque, absorbing collision energy and providing safety protection.
Firstly, controlling the driving direction of the car is the basic function of the direction column. The driver rotates the steering wheel and the tube column transmits the torque to the steering device, thus controlling the driving direction of the vehicle . In addition, the steering column also has a torque transmission function to ensure that the driver's steering command is accurately communicated, so that the car can change direction according to the driver's intention .
Secondly, absorption of collision energy is the key role of directional string in safety. When the vehicle crashes, the directional column can absorb the impact force and reduce the injury to the driver. The steering column in modern vehicles is often equipped with an energy absorption design to reduce the distance the steering wheel has to move back during a collision, reducing the risk of secondary injury to the driver and passenger, thereby improving the vehicle's passive safety .
In addition, the directional pipe column also has the adjustment function to meet the needs of different drivers. Some directional columns can be adjusted up and down, front and rear, providing a more comfortable driving experience . At the same time, after connecting with the ignition lock, the directional column also has the anti-theft lock function to increase the safety of the vehicle .
Finally, the design and type of directional column are diverse, common hydraulic power, electric hydraulic power and electric power steering column. Different types of directional columns are suitable for different steering systems to meet different driving needs .
A broken decbyte of the steering column can cause a variety of symptoms, including:
Abnormal sound : when you turn the steering wheel in place or drive at low speed, you will hear an abnormal sound .
heavy steering wheel : feel unusually heavy when turning the steering wheel, need to spend more effort .
running off : the vehicle is easy to run off when driving on the straight road, it is difficult to maintain a straight line .
free travel gets bigger : Steering response becomes dull and less accurate .
jitter : The steering wheel jitter when steering, affecting the stability and comfort of driving .
Dashboard fault indicator on : The steering power system fault indicator on the dashboard may light up .
difficult to control : oversteering or understeering, resulting in difficulty controlling the vehicle .
Cause analysis
Causes of decbyte damage to the directional string may include:
Wear : cross shaft wear leads to increased clearance, causing abnormal noise and operation difficulties .
uneven force : the vehicle runs for a long time, the torque direction is the same, resulting in aggravated wear on one side of the cross shaft .
insufficient lubrication : lack of lubrication or poor lubrication, increasing friction and wear .
Design or manufacturing defect : In some cases, design or manufacturing defect may also cause decbyte damage .
Maintenance proposal
Check and lubricate : If symptoms are mild, try pouring just the right amount of grease to reduce friction .
Replacement parts : If the wear is serious, need to replace the cross shaft or the entire direction assembly. This usually needs to be done in 4S shops or professional auto repair shops, and the cost is higher .
Four-wheel positioning : after replacing the parts, the four-wheel positioning must be adjusted to ensure the driving stability of the vehicle .
