How to adjust the large gap of the steering wheel, and how to judge whether the gap of the steering

There will be gaps in the steering wheel of any car, which is caused by the twisting of the steering pillar itself. As the vehicle is used year after year, the gap between the steering wheels increases. This is because the wear of the rack and pinion of the steering machine and the wear of the connecting parts of the suspension create a large gap, which makes the steering wheel have to turn at a relatively large angle to make the vehicle turn.

The steering wheel clearance will make the vehicle less controllable, and it will be a little floating on the road.

The steering wheel clearance is large, and there is basically no adjustment, but it can only be seen from the steering wheel to the steering machine to the tie rod that part is worn. The more common ones are the wear of the cross shaft of the direction column, the wear of the rack and pinion of the direction machine, and the wear of the ball head of the tie rod.

The cross shaft of the directional column is essentially a universal joint, which is used to change the direction of the directional column torque and to avoid the directional column poking the driver in the event of a serious accident. Worn cross-axles cause a large steering wheel clearance and sometimes a rattling sound.

There will be a certain amount of wear and tear in the rack and pinion of the steering machine, especially the habit of not returning the steering wheel to the right when stopping, which will make the rack and pinion bear greater pressure and accelerate the wear. When the wear of the rack is not particularly serious, the clamping force of the rack and pinion can be increased by the adjustment screws on the steering machine, but the corresponding steering wheel will become heavy.

Tie rod ball joint wear is a relatively common fault, and there are inner ball joints and outer ball joints in the direction machine of the car. The inner ball head is connected to the tie rod and the rack of the direction machine, and the outer ball head is connected to the horn and the tie rod. By lifting the car and shaking the wheels by hand, you can feel the gap between the ball joints and hear the gurgling sound.

If the steering wheel clearance is too large, it should be the steering gear or the direction cross joint and the tie rod ball joint, if the ball joint is worn, it can only be replaced with a new one, it is recommended to repair it. 1.A steering gear is a device that converts manned and unmanned mechanical devices with a power source to randomly change the running route and direction during operation.

The steering gear is also known as the steering machine and the steering machine, and it is the most important in the steering system.

1.When the engine is turned off, stop in place and turn the steering wheel to the left and right, and the amount of rotation between the steering wheel from left to right is the free travel clearance of the steering wheel, note that the steering wheel of the car rotates with the rotation of the steering wheel.

2.Under normal circumstances, the free stroke clearance of the steering machine is about 10-15mm. If the gap is too large, it will generally feel that there is obvious open momentum or accompanied by abnormal noise, and the steering wheel gap will also make the vehicle's maneuverability decrease, and drive a little floating, the steering machine gap should be in time to the 4S shop for maintenance and inspection, to prevent the fault from further expanding.

3.The wear of the rack and pinion of the steering machine and the wear of the connecting parts of the suspension will make the steering machine produce a large gap, and the gap of the steering machine is large, and the steering wheel must turn at a relatively large angle in order to make the vehicle turn during the turning process.

A simple preliminary judgment can be made in the following way, provided that in the state of engine shutdown, turn the steering wheel to the left and right sides in situ, until the steering wheel rotates with the rotation of the steering wheel, the rotation of the steering wheel from left to right is the free travel clearance of the steering wheel, under normal circumstances, this gap is very small, if the gap is too large, it will generally feel that there is obvious open momentum or accompanied by abnormal noise, In that case, you need to go to the 4S shop in time to ask the maintenance technician to conduct an on-site test inspection and judgment.

The car steering wheel gap is large and only needs to be re-adjusted, and there is an adjustment switch under the steering wheel, and the specific steps are as follows:

2. Then pull the handle and press down until it reaches the lowest position.

3. Then you can move the steering wheel up and down with your hands, which can be adjusted according to the front dashboard as a reference and your own sitting posture.

4. When the upper digs down and moves the steering wheel, the spatial distance on this side of the figure will change with the will.

5. After the final adjustment is completed, turn off the adjustment switch back until it is completely closed, and then move the steering wheel up and down to check whether it is stable.

Excessive steering wheel clearance may be caused by wear and tear on the steering machine and steering column after the vehicle has been used for a long time and the number of kilometers has increased.

Common points of failure are:

It may be that the rack and pinion inside the steering machine are worn, resulting in too large a gap between the rack and pinion, so the gap of the steering wheel will also feel too large.

2.It may be that the cross gimbal inside the steering column to which the steering wheel is connected is worn, causing the clearance of the steering wheel to be too large.

3.It may be that the airbag hairspring under the steering wheel is worn out, causing the gap in the steering wheel to be too large.

The above are common fault points, it is recommended to check them as soon as possible.

2. Next, you only need to press the handle of the reverse disk switch to the very bottom.

3. At this time, you can move the steering wheel of the vehicle up and down.

4. Then when moving the steering wheel of the vehicle up and down, the gap of the steering wheel of the vehicle can be adjusted in place.

5. Finally, after adjusting the steering wheel clearance of the vehicle, buckle the adjustment switch back to the top.

Cannot be adjusted.

The steering wheel clearance becomes larger because of the usual wrong driving habits, the solution is to do a four-wheel alignment, then adjust the steering machine, and check the clearance size of each connecting part.

Try not to kill the steering wheel when you usually use the car, especially not to kill it in place. Many riders don't know how many turns the steering wheel will be killed, so you can return to the right a little after being killed when using the car, which can protect the steering machine and transmission mechanism.

The increase in the steering wheel clearance may be caused by the larger clearance of the transmission mechanism in the middle, or it may be caused by the larger clearance of the steering machine. It is recommended that all riders turn the steering wheel back to the center after parking. Don't go on some curbs when driving, as they are harmful to the steering system and suspension system.

After the steering wheel clearance becomes larger, you should go to the maintenance agency in time to check and then adjust the clearance. The steering wheel has a clearance when it leaves the factory, but the clearance of the factory is within a reasonable range, and after exceeding this reasonable range, it will affect the handling of the vehicle.

Larger clearances can lead to inflexible steering, which can lead to traffic accidents in the event of an emergency. On some heavy rainy days, if the water on the road can cover the chassis of the vehicle, then do not drive on the road. Rain that does not pass through the chassis can damage the steering gear.

In fact, there is no way to reconcile. It is only possible to see whether the steering rod pins and spherical bearings or pin sleeves are loose or not. If it is normal, it will not loosen.

The free clearance of the steering wheel is beneficial to alleviate the impact of the road surface, make the steering soft and reduce the fatigue of the driver, but when it is too large, it will affect the sensitivity of the steering and the oscillation of the wheels, which affects the driving safety. The free rotation angle of the steering wheel is generally 20 degrees, and 30 degrees is appropriate. Therefore, the free clearance of the steering wheel has become one of the important inspection items in the annual inspection of the car.

Steering wheel clearance is caused by improper assembly or adjustment between the steering system and the steering wheels, or by wear and tear of the components. Specifically, the meshing clearance of the steering gear transmission pair is too large; The connection of the steering transmission mechanism is loose; The gap between the steering knuckle kingpin and the bushing is too large; Steering wheels, hub bearings, loose bearings, etc., of which the first two have the greatest impact. The free clearance of the steering wheel should be inspected in a segmented manner and analyzed one by one.
