On the slippery wheels when they turn, there is a bit of a problem

The bearing rings when they are not tightened.

Did you remove the brakes and find that the screw had grown out of a section?

Go find the spacer and pad it well, there will be no sound and it will be smooth!

You take a good wheel down and compare it to see what's the difference.

Because you say that, we can only imagine the situation of your shoes.

You can see what the problem is when you compare two wheels.

There are also brackets to see if there is any deformation

If you're deformed, there's no salvation unless you're patient, and you can correct it little by little.

Pressing the inside edge is because your shoes are not enough to support the problem!

The support force is simply said to be the material used in the shoe to determine the degree of closure of the shoe body and the bracket, the stronger the material, the better the support.

You have to try the body of the shoe to be semi-soft, that kind of shoe should not be too exaggerated, otherwise the bracket and the body of the shoe will be loose.

You can't tell if you try to.

Put on your shoes and press the balls of your feet to the inside and out, if you swing too much, you will definitely not have enough support.

Has the bearing been repaired?

Is it that the brakes were removed and the screw was not replaced. It has to be tightened with a short thread.

How? Inverted? Try to stand up straight and see, if you stand up straight, it's a problem with your shoes.

Let's get a new pair.

There is a problem with the shoes.

It seems that there should be a deviation in the hole position of the shelf.

Then there is the reason why the length of the nails mentioned above has not been replaced.

The sound about the creaking should be the sound of plastic rubbing.

There are several reasons for this:

1. If the wheels of the skateboard are broken, you can replace them with new ones.

2. If the slide bearing is rusty, you can use gasoline to clean the rust on the bearing, and then apply lubricating oil.

3. The slide bearing is too dry, so it is good to lubricate the bearing directly.

Hardness

Skateboard wheels are usually rubbed polyurethane as the main material, and the hardness of the wheels is different due to the different proportions of polyurethane in the wheels. The wheels with a hardness of 85A (A refers to hardness) are relatively soft, suitable for sliding on rough roads, and the sound is very small when sliding, which is a good choice for friends who like to pedal and go shopping.

However, the wheels of the 85A are relatively wear-resistant because they are soft, and it is easy to break the spacer layer when doing actions such as side-slip brakes. Generally, skaters use 97a-103a wheels.

This type of hard wheel is suitable not only for smooth marble and flat road surfaces, but also for props such as U-pools, jumping platforms, etc. In smooth and flat places such as 85a wheels, there is no sound. It is not recommended to use 103a for transparent or translucent wheels, it is too hard and will burst, so it is best to only use it on props made of all wood materials.

If the lubricating oil is not enough or the bearing is broken, you can try to replace the bearing, or if you marry the display, there are particles.

When one wheel of the car slips, the corresponding reason why the wheel on the other side does not rotate is: the differential of the car plays a corresponding role and gets the car out of trouble in time.

The automobile differential is mainly composed of left and right half-shaft gears, two planetary gears and gear carriers. Its function is to adjust the speed difference between the left and right wheels and the device, when the car turns or when driving on uneven road surface, the existence of the differential can make the left and right wheels roll at different speeds (reasonable torque distribution), so as to ensure that the driving wheels on both sides do pure rolling motion.

Don't underestimate the existence of the differential, if there is no differential or abnormality, due to the inconsistency of the speed of the left and right wheels, the wheels will inevitably slide while rolling. Not only does it accelerate the wear of the tires, but it also increases the stress on the axles.

There is a differential in the middle of the rear wheel, otherwise it will not be able to turn to the corner, when turning, the inner wheel should turn slower, which is his role, so now some trucks have a differential lock, which can prevent a wheel from turning into the mud and other effects.

Because the two wheels are not connected by one shaft, but two half shafts, the power of the two half shafts comes from the reducer housing, and the sum of the speed of the two half shafts at any time is equal to twice the speed of the reducer shell.

The function of the differential, specifically the planetary gears in the differential package, is that the car is driven by only one set of wheels when turning or stranding, and only the group of wheels with lighter force is driving when the car is turning or stranding.

Hello dear, one of the wheels of the skateboard turns slower than the others, which may be caused by the following factors:1The wheels are stuck :

It is possible that the bearings are blocked or the wheels are stuck and worn out, so you need to remove the wheels, clean the wheels and bearings, make sure they are clean and smooth, and then put them back on. 2.Bearing wear:

If the wheels are difficult to turn or the shirt is turning louder, it may be that the bearings are worn. At this point, the bearings need to be replaced to allow the wheels to rotate more smoothly. 3.

Unbalanced wheels: Check the wheels for dents, deformations, or imbalances, which may cause the wheels to rotate poorly. 4.

Loose: Check if the wheels are installed firmly, if they are loose, they need to be reinstalled.

Hello, I'm glad to answer for you, the following is the answer to your query, I hope it will help you. Why does one of the wheels of the skateboard rotate so slowly The slow rotation speed of the wheels of the skateboard may be caused by the following reasons:1Bearing Problems:

Bearings are one of the key components for wheel rotation. If the bearing is damaged, worn, or lacks lubrication, it increases friction and slows down the wheels. 2.

Axle nuts are too tight: The wheels of the skateboard usually need to be fixed to the axle of the scooter. If the axle nut is overtightened, it will cause increased friction between the wheel and the shaft, which will slow down the rotation.

3.Inconsistent wheel drain diameter: If the wheel diameter on the skateboard is inconsistent, one of the wheels will turn slower than the others.

This can be caused by manufacturing issues, differences in usage time, or worn wheels. 4.Wheel wear:

After a long period of use, the wheels of the skateboard will wear out, and the grain on the surface of the tire will become lighter, which will reduce the friction between the wheel and the ground, resulting in a slower rotation. 5.Ground friction:

The friction of the ground also affects the speed at which the wheels turn. Different ground materials or impurities such as dust and sand will increase the friction between the wheels and the ground, slowing down the rotation. If you find that one of the wheels of the skateboard is not rotting and moving slowly, you can first check whether the bearings are in good condition, clean and lubricate.

Check whether the diameter of the wheels is consistent, if there are inconsistencies, you can replace the wheels. In addition, regularly inspecting and replacing worn tires is also a step to keep the wheels turning.

Because one foot does not move when turning.

The easiest way to do this is to keep one foot moving and push the other foot outward, then retract and kick out again, and repeat it a few times to turn over.

Basic Information. Standing posture: One is ordinary parallel standing, that is, the two feet are parallel and slightly narrower than the shoulders, the knees are slightly bent to maintain the center of gravity, and the ankle strength is controlled not to let the feet swing left and right, and the wheels are perpendicular to the ground.

When wearing professional flat shoes and standing parallel to each other, due to the influence of the structural design of the shoe, the feet will naturally press outward against the outer edge.

The second is a T-shaped stance (also called a T-shaped stance) applied to non-level ground, that is, the last wheel of one shoe is pressed between the second and third wheels of the other shoe, the knees are slightly bent, and there is a slight gap between the legs to maintain the center of gravity, and the shoe is still controlled by the ankles.

Start: Start from a T-shaped position, keep one foot forward, toe forward, and push the other foot out of the back of the body, and you will have the power to move forward. At this time, the center of gravity of the body should be completely on the front foot, and the body should be slightly leaned forward (not hunched), so that the force of the back foot can be retracted smoothly.

After the back foot is retracted, the other foot is pushed out to the back of the side of the body, and the center of gravity is still placed on the front foot, and so on.

The center of gravity of the body: The center of gravity of the body should always lean forward slightly when gliding, and the center of gravity should constantly shift as the feet continue to alternate. When one foot is pushed out to the side of the back, the weight of the body must be completely on the other leg to ensure that the leg is smoothly retracted.

When this leg retracts to the ground, the weight immediately shifts to this leg and pushes the other leg out.

Remember to keep your weight completely on the other leg each time you press your leg. And so on and so forth.

Gliding position: Bend your knees slightly and lean slightly forward to maintain your center of gravity. The faster you glide, the more you bend your knees.

The standard speed skating position is to have your hands behind your back (without swinging arms), with your back parallel to the ground, and your thighs and calves bent at an angle of no more than 120°.

Stop: Slide in the above position, keep your feet close to each other and keep them parallel, the foot with the brake pad is slightly forward, so that the distance between the two feet is about half a foot, lift the toe until the brake pad touches the ground next to the surface, and then slowly shift the weight to the foot with the brake pad to increase the pressure until you stop.

Upstairs rookie, don't listen to him.

The wheel can roll without sliding, sliding without rolling, rolling and sliding, three states of motion.

Rolling and sliding can be seen as two separate movements, rolling is due to unbalanced moments, sliding and having acceleration to dissipate.

It is the force imbalance, first of all, the wheel from rest to motion, if the direction of the resultant force is horizontal and the moment is balanced, as shown in Figure 1, then slide without rolling, the acceleration of all points of the wheel is equal, the condition of the moment imbalance is that the extension line of these forces does not collapse at one point, if you want to judge whether there is also sliding at the same time under the condition of rolling, then it depends on the linear speed of the wheel.

The wheel as a whole (that is, the centroid.

The forward velocity, i.e. r=v is not true, having said that, the condition for rolling without sliding is the velocity, acceleration, angular velocity of the point where the wheel touches the ground.

The radius is equal to the quick-auspicious roundness, acceleration, velocity of the centroid of mass.

The frictional force f between the wheel and the ground is greater than the pulling force f that pulls the wheel
