What to do if the two sides of the electric car are unbalanced

Sitting on it when the big brace is propped up, causing it to tilt to one side.

It should be adjusted to a 30-degree bevel angle to be more stable.

One person is holding the car, and the other person opens the diagonal brace and pulls it hard to the left with his hands.

some, then put down the car and look at the angle until you feel the right angle. Diagonal bracing is an architectural term, which sets a spanning layer on the façade of the building to form a space truss, which effectively increases the stiffness of the structure and increases the seismic capacity of the structure.

From a biomechanical point of view, the rotation of each side of the crank set involves three joints of the human body, which need to be stretched and bent to complete a pedal, so the calculation of the lever on the crank set is much more than the length of the crank.

However, if the conditions are limited to a certain range, it is true that a longer crank is better for speed. In one study, using a fixed-tooth bike, the acceleration test was done at a distance of 100-200m, and indeed the longer crank got faster speed, even if it was only a 2mm difference, which helped.

The length of the crank also has an impact on how the rider balances the weight on the bike. For example, an average man feels a little top-heavy because of the more weight in his upper body, so a longer crank can be more conducive to his high balance in the car. And for female riders, it's the opposite, so often a shorter crankset is better.

If the electric handle is used for a long time or the quality is unqualified, there will be inflexible rotation and poor contact, etc., it is recommended to replace the new handle, about 15 yuan.

We power up the handlebar on the electric car, also known as the handlebar, if the turn is heavier, you can loosen a small hexagonal screw, and move the handle to the outside a little, it will be easy, if it is the direction of the turn handlebar to rotate and sink, that is, the bearing of the direction column is worn, and the rolling is not flexible, and the bearing of the direction column needs to be replaced.

Precautions for electric vehicle maintenance.

When the electric bicycle is just started, it is necessary to use the pedal (if there is no pedal, you can push the ground with the foot) to help start, and when going uphill, use the pedal to help the electric vehicle go uphill, so as not to damage the battery due to excessive discharge current.

When riding, it is necessary to pay attention not to let the battery be over-discharged, and after the battery is discharged to the termination voltage, it is called over-discharge. Over-discharge is easy to cause serious power loss of the battery, which greatly shortens its service life. Therefore, when the battery is used, it should be avoided as much as possible to avoid deep discharge, so that it can be charged shallowly, and the general situation should be:

It is best to charge the battery once when the depth of discharge is 50%.

As follows: the rear wheels of electric vehicles rotate very heavily, and most of them are not well adjusted by the brakes of the rear wheels. First adjust the length of the brake line appropriately, if it is still very heavy at this time, you should adjust the screw next to the green, and turn left and right, its function is to make the brake shoe in the middle position, and the shoe and the brake pot keep an equal gap.

Adjust it repeatedly, turn the rear wheel by hand, there should be a little bit, the friction sound is minimal, and it is adjusted at this time. You can try it yourself, but if you can't adjust it well, you can only ask someone to adjust it.

Maintenance method: 1. Brake pad replacement. Usually we use whether the brake warning light on the dashboard is on as the basis for judging whether the brake shoes should be changed, but this is the bottom line.

Therefore, it is necessary to check whether the brake pads can be used at every time they enter the factory for maintenance, and replace the brake pads that are close to the bottom line of life early.

2. Daily maintenance of the brake system. Clean, high-quality brake fluid is essential for safety and good braking system function. You should buy a good quality brake fluid on the market. All discharged brake fluid should be discarded.

First of all, it may be because the brakes of the electric vehicle are too tight, resulting in the handlebar being particularly heavy and difficult to control, and it may also be because the steering column or nut of the electric vehicle is deformed, resulting in the handlebar being particularly heavy.

The handlebar is tilted to both sides, first check whether the fork is not correct, and then the pressure bearing inside the fork is faulty. These two faults can cause the fork to mistrack.

This kind of failure should be the failure of the upper and lower pressure bearings in the handlebar, and the two upper and lower bearings will be replaced with a new handlebar, which will be normal.

In this case, you can consider replacing the steering bearing of the electric vehicle, or the flat fork of the electric vehicle is a little bent, and the electric vehicle deviates from these two situations.

Because the electric car is two-wheeled, it can't stand when it doesn't move, and it can only maintain balance through inertia when driving, and if you haven't learned to ride a bicycle before, it takes a few days of practice to master the balance.

When novices practice balancing, they need to keep the car upright and start the throttle slowly, but to ensure that the car has enough power, if the throttle is too low, the car is easy to crook, and the balance is difficult to maintain.

When practicing cornering, you should master the conversion of the throttle, and you can slow down appropriately. In case of an emergency, pinch the handle of the emergency brake.

At the beginning, the hands and feet will definitely feel less coordinated, and you may remember the movements of the right hand, and you may forget the movements of the left hand, but as long as you practice diligently, you will overcome them.

The balance trick of riding an electric car is: relax your body, don't be too nervous, don't use too much force to grab the handlebars, if you grab the handlebars too hard, your hands will be sore for a while, and the handlebars will be unstable. Keep driving at a constant speed, never screw the throttle knob to the head, slow speed in the early stage, keep it at about 10-20km, and practice slowly for a few days.

Keep a relatively safe distance between the car, and the car and pedestrians must keep a safe distance from the car and pedestrians, after all, it is the beginner stage.

Can be adjusted.

One person was holding the car, and the other person opened the diagonal brace and pulled it to the left with his hand.

some, then put down the car and look at the angle until you feel the right angle.

Electric bikes.

It has been favored by the middle and low-income classes in the city for its low-cost, convenient and environmentally friendly functional advantages. China's electric bicycles have been growing significantly year by year from research and development to small batches on the market in the mid-nineties of the last century, and production and sales since 2012. Due to the strong demand, China's e-bike market has been growing by leaps and bounds.

Domestic progress

As a green sunrise industry, electric vehicles have been developing in China for ten years. In terms of electric bicycles, by the end of 2010, China's electric bicycles had reached 100 million, and the annual growth rate was 30%.

From the perspective of energy consumption, electric bicycles are only one-eighth of the time of motorcycles.

1. One-twelfth of a car; From the perspective of occupied space, an electric bicycle occupies only one-twentieth of the space occupied by ordinary private cars; From the perspective of development trends, the market prospects of the electric bicycle industry are still optimistic.

Data show that in 1998 the national output was only 10,000 units, in 2002 it was 1.58 million units, and in 2003 China's electric bicycle output reached more than 4 million, ranking first in the world, with an average annual growth rate of more than 120% from 1998 to 2004.

Summary. The abnormal noise of electric vehicles is generally the following situations:

First, the sound caused by the disc brake is very common, because the accuracy of the accessories is not very good, and the factory is an assembly line operation, many new wheels are not very easy to turn, and the resistance is relatively large. The friction between the disc brake pads and the disc causes an annoying sound, and generally this kind of problem, the favorite of selling cars is to say that it is good to run in, a small problem. During this period, you have to endure the sound.

Many repair shops won't debug it for you.

If the assembly is not good, the disc brake pad will be scrapped in advance, as shown in the figure below. To solve this problem, you need to understand the principle of disc brakes.

Solution: 1. Due to process problems, when installing the disc brake, the disc brake pad and the disc disc are not in a straight line, and the appropriate gasket can be added to the fixing screw for adjustment; Second, the disc brake oil can not be added too full, so it is easy to have a sense of expansion, you can use an 8mm wrench to loosen the exhaust screw, put a few drops of oil. 3. The disc brake blade is worn to the iron plate, and it will croak, so replace it in time.

The disc disc is damaged, which affects the braking effect, accelerates the wear rate of the disc brake pad, and increases the maintenance cost.

Is it better to have a side support or a rear support for an electric car to make a loud noise.

The rear support of the newly bought electric car will be stepped on when the road conditions are bad.

Specifically, it is recommended to check the place where the car is sold.

Hello, I am happy to serve you and give you the following answers: The reason why the battery car is installed in the middle support may be that the battery of the battery car is insufficient, or the battery of the battery car is damaged, or the battery of the battery car is in poor contact. Workaround:

1.Check the battery level of the battery car, if the power is insufficient, it can be charged; 2.Check the battery of the battery car, if the battery is damaged, you can replace it with a new one; 3.

Check the battery contact of the battery car, if the hall resistance is not good, you can clean the battery interface, or replace the battery interface. Steps:1

Check the battery level of the battery car: open the battery cover of the battery car, check the battery level, if the power is insufficient, you can use the charger to charge; 2.Check the battery of the battery car:

Remove the battery, check whether the battery is damaged, if it is damaged, you can replace it with a new one; 3.Check the battery contact of the battery car: remove the battery, check whether the battery contact is good, if it is bad, you can clean the battery interface, or replace it with a new battery interface.

Personal experience: The reason why the battery car is installed with a medium support may be that the battery is insufficient, the battery is damaged, or the battery is in poor contact, therefore, when using the battery car, the battery level should be checked regularly, check whether the battery is damaged, and check whether the battery contact is good to ensure the normal use of the battery car.
