What s the deal with the rear wheels locking up as soon as the electric car is powered on?

What is the reason why the rear wheel of the bottle car is locked.

There are several possibilities for the rear wheel to lock, the common ones include the brake locking and the motor not turning, or the motor not turning due to the internal jamming of the motor.

If it is caused by the internal rotation of the motor, it is divided into a locked motor and a non-locked motor, and the motor with a lock directly checks the motor lock. If it is not locked, check the coil for short circuits. If the brakes are locked, the fault is relatively easy to solve, the owner can try to adjust the brakes, you can try the hydraulic brake to let it out a little hydraulic oil.

Take a look, or adjust the brake screws. There is also a situation where the owner wades through the hose after washing the car or in the rain and pulls the handbrake.

Brake pads that appear after a long period of parking.

Caused by rusting with brake drums. You can try to move the vehicle forward and backward about three times frequently, but be careful not to force the tires back and forth if it doesn't work. If it doesn't work to move forward or backward, you can use boiling water, the temperature is as high as possible, pour it on the brake pads, and try to separate the brake pads from the brake drum.

1. The locking phenomenon of the rear wheels of the battery car, braking system.

Water ingress causes the blisters to swell in the leather bowl of the brake master cylinder, which needs to be replaced immediately.

2. The stiffness of the brake disc is not enough, when the braking system is not strong enough due to the insufficient stiffness of the brake disc after frequent braking, the brake disc is deformed at high temperature.

3. After the brake disc is deformed, the wheel may lock up when it is used next time, and the brake pad needs to be replaced in time.

4. The brake pad is unreasonable, and the brake pad is originally semi-metallic.

Brake pads, brake pads and brake drums are easy to stick, which is a problem of oxidized rust adhesion, and the configuration of brake pads needs to be reasonably determined in the design stage.

5. The strength of the return spring is not enough, the brake pad is seriously worn, and the return lever interferes with other components.

This is due to a malfunction in the braking system of the rear wheels, and when such a situation occurs, it is advisable to repair the braking system of the rear wheels. Electric car is a more often encountered means of travel, such a means of travel is more suitable for driving in congested urban roads, the size of electric vehicles is small, and the space occupied is also relatively small.

The key components of an electric vehicle include the frame, electric motor, battery, and electronic control system.

Most of the electronic control system will be installed under the back seat, the function of the electronic control system is to adjust the whole car circuit, if there is no electronic control system, the electric car is unable to operate normally.

The electric motor is the first of the electric vehicle power, and the electric motor is responsible for driving the electric vehicle forward.

The battery is a part of the electric vehicle that stores electrical energy, and this part can also supply power to the electronic devices of the whole car.

The battery is also a wearing part, and the performance of the battery may also decrease as the number of charge and discharge times increases.

Of course, batteries need to be replaced regularly.

When charging or discharging, the ions in the battery will move in the electrolyte, and some ions will chemically react with the electrolyte as they move in the electrolyte.

As the number of charge and discharge times increases, the number of ions in the battery may also decrease, and it is natural that the performance of the battery will decrease.

If you can maintain accurate car habits, this can still have the effect of extending the service life of the battery.

First disconnect the three phase wires connected to the motor and the controller, if the wheel is no longer locked after powering at this time, you can judge that the controller is damaged, and you need to replace it with a new controller.

As soon as the electric car is powered on, it locks up.

Let's talk about following to become the 6th fan.

Judging from the situation you described, it is generally a phenomenon generated by the brushless Hall motor and the controller, and you observe whether there is a problem with the Hall connection of the motor. Check whether the color of the wires plugged in the connection between the motor and the controller is consistent, and then check whether there is any problem with the motor hall. If you can't handle it yourself, you can go to the repair point and ask him to inspect the motor Hall.

The rear wheel motor of the electric vehicle suddenly locks up and hits while driving, and how to repair it depends on the master's detailed explanation.

A small trick, the solution of suddenly locking the rear wheel of the car during electric car riding, and not moving forward.

First of all, it is necessary to distinguish whether the brake locks the motor does not rotate, or the motor does not rotate caused by the internal jamming of the motor, the brake locking can be adjusted or adjusted, and the hydraulic brake can be relieved of a little hydraulic oil, and the motor has to be replaced if the motor is stuck.

Check the motor lock for the motor with a lock.

If it is not locked, check whether the coil is short-circuited.

If the brake is locked, you can adjust the screws, and if the motor is stuck, then you have to change the parts.

The safest way is to tow the vehicle to a professional car repair shop for a full inspection, replace the "five oils and three waters", and focus on repairing the brake system.

1. Frequent forward and backward about three times, if it is still invalid, please use the second solution; Note: Do not forcibly drag the tires back and forth many times, as there is a risk of severe tire wear.

2. Use boiling water at 100°C, pour it into the position of the brake pads, and then repeat method 1, the brake pads and brake drums are heated and expanded, and may be automatically separated.

Vehicles are parked for a long time, it is very important to choose a parking place, on the basis of ensuring safety, try to avoid sun and rain, do not park in the downstairs of the community, under the trees, direct sunlight, low-lying places, can not be parked in the underground parking lot with imperfect drainage facilities, and it is best to choose the above-ground indoor parking lot if there are conditions. If possible, try to start the car every week and drive more than 10 kilometers each time, which is the best way to prevent the car from aging.

Hello, I am inquiring about the relevant information for you and will reply to you immediately.

Dear, hello, 1. Start the car, drive forward and then back three times, don't drive too much, otherwise there is no separation of brake pads and brake drums, resulting in the tires being forcibly dragged and moved and worn. 2. Prepare boiling water, pour 100 degrees of boiling water between the brake pads and the brake drum, it may be automatically separated after being heated and expanded, and then re-use the above method, and the tires may not lock up when moving forward and backward. 3. Use a rubber hammer to align the brake disc and knock it on both sides, and it is possible to separate; If you can't, you can kick your foot against the tire a few times, and you may separate; If you can't remove the tires again, disassemble and install the brake pads.

4. If the previous methods have been tried, the wheels are still in a locked state, and because you don't know the brake pads of the brake drum, you need to go to the staff for maintenance.

There are several possibilities for the rear wheel to lock, and the biggest possibility is that the brake calipers do not rebound.

After the electric vehicle is energized, the rear wheels will lock, which can be caused by two reasons, 1, the controller of the electric vehicle is damaged, 2, the motor coil or Hall of the electric vehicle is burned out, and it is generally more likely that the controller will lock up if it does not accelerate.

Hello 1If the rear wheels of the electric car are locked, it is best to call the repair shop and pull the electric car out for repair, because if the electric car is pushed away, it.

2.Generally speaking, the rear wheel locking of an electric vehicle is mainly due to the mechanical reason of the motor caused by the stuck phenomenon, and the specific reason is control.

3.An electric car suddenly hugged the rear wheel, did not leave, could not push, the rear wheel shook a little. When the power is on, the rear wheels will be.

4.Causes: bad controller or phase misalignment or short circuit, phase wire heat, insulating skin melting, phase wire poor contact; The phase wire is short-circuited, and the wheels are difficult to push.

Just change the brakes.

Pay attention to the maintenance of the vehicle, especially after the front brake is a drum type electric vehicle after driving a long mileage or parking for a period of time, be sure to go to the repair shop to check.

On rainy days, push the carport as much as possible, and if there is no carport, you should also find a way to cover the wheels of the car.

Pay attention to driving habits, drive slowly in rainy days, do not soak the wheels of the car in water, and try to detour when encountering puddles.

Remove the rear wheel for maintenance, you can't repair it yourself, you have to find a professional person to repair it.

It should be a problem with the brakes, if it is the front wheel, the brake can be removed, and it can be replaced, if it is the rear wheel, loosen it, if it is not good, the motor magnet falls off.

It's best to find an electric car repair shop and let a professional master repair it. This sort of thing is not.

Things that can be explained in one or two sentences.

Generally, the controller is burned out, to see if the motor phase wire is stuck together (yellow, green, blue from the motor) It is recommended to find a professional to repair it.
