Electric tricycles are used as new shipping tools. Also known as "flat three-wheel", there are many brands, but its form and structure, the parts of each part are basically the same size. The quality of electric tricycles is different only because of differences in materials and manufacturing processes. So how should the user maintain the repair? How to maintain and maintain the electric tricycle in the following small series? What are the common faults and maintenance methods for electric tricycles? Let's get to know it!

Maintenance and maintenance of electric tricycle

(1) Before riding, check whether the battery box is locked and whether the display panel lights are normal.

(2) When driving on a stagnant water surface in rainy days, the water depth does not exceed the normal driving of the center of the electric wheel. If the water depth of the road surface exceeds the center of the electric wheel, it may cause the electric wheel to seep and cause a malfunction.

(3) The whole vehicle should be placed in a place where the air is humid, the temperature is too high, and corrosive gas is present, so as to avoid chemical corrosion of the electroplated paint surface of the metal parts.

(4) It should be avoided that the whole vehicle will be exposed to the sun for a long time and rain, so as to avoid damage to the components inside the controller, resulting in malfunction and accidents.

(5) The electrical control part has a complicated structure, and the user should not disassemble or repair it without authorization. If the local charging voltage is unstable, it is easy to blow the charger fuse. It is recommended to use an AC voltage regulator.

(6) The electric bicycle feels heavier when it is reversing, and it is normal to have a slight friction sound in the forward propulsion hub.

(7) Cycling should not be overloaded. Heavy objects and people should not be placed to avoid damage to the battery and motor.

(8) Lubrication of bicycles is an important part of maintenance of bicycles. According to the use situation, parts such as front axle, rear axle, central axle, flywheel, fork, and suspension pivot support should be scrubbed and lubricated every six months to one year ( It is recommended to use molybdenum disulfide grease). The transmission components in the electric hub have been coated with special lubricants, so users do not have to scrub the lubrication themselves. If abnormal conditions are found, you can go to the company's special maintenance point for maintenance.

Daily maintenance of electric tricycles:

1. When adjusting the height of the saddle, note that the safety line of the saddle should not be exposed outside the tube.

2. When adjusting the height of the handlebar, pay attention to the safety line of the riser should not be exposed outside the front fork lock.

3. Check if the brake power-off device is in good condition, hold up the bracket, open the electric door, rotate the right turn handle, start the motor, and then gently hold the left brake lever. The motor should be able to power off quickly and gradually stop rotating. At this time, if the motor cannot be powered off, stop the drive and ask the professional to repair it before use.

4. Before driving, check the electrical plug of the battery box, whether the polar seat is shaking, whether the electric door lock is flexible, whether the battery box is locked, whether the speaker and light button are valid, and whether the light bulb is good.

5. The saddle height of the electric tricycle is adjusted so that the rider's feet can be grounded to ensure safety.

6. After the air is charged to a certain pressure, turn the rim to hit the tire evenly by hand, and then continue to inflate to make the tire and the rim match, so as to avoid the phenomenon of slipping tires during riding.

The recommended torque of the horizontal pipe, the riser pipe, the saddle, the saddle pipe and the front wheel is 18N.m, and the recommended torque of the rear wheel is 3ON.m. It is strictly forbidden to oil the front and rear brakes and tires.

7. The front and rear brakes should be flexible and can be quickly reset by the spring force. After the brakes, the gap between the brakes and the sleeve should be left at a finger distance. The brakes on both sides are parallel to the rim. The deviations are up and down and left and right.

8. During winter riding, because the low temperature makes the capacity of the battery pack drop, the same riding distance, the depth of discharge will increase, and the pedal assist will help to extend the service life of the battery.

9. The maximum speed of electric tricycle is 20km/h, but the wind resistance of long-time driving is also large, which affects the mileage of one-time charging. Therefore, it is recommended that the speed should be controlled at 15--18km/h.

10. The electric tricycle is designed to have a load of 100kg, so to remove the weight of the rider, avoid wearing too heavy objects. When loading the load, apply the pedal boost.

11. In order to ensure safety, the electric tricycle's electric door should be opened when getting on the train. When parking or pushing, the electric door should be closed in time to prevent the unintentional rotation of the transfer, causing the vehicle to suddenly start and cause an accident. It is recommended to use the pedal boost when going uphill.

12. Electric tricycles are not suitable for driving on uneven or steep roads. If the vibration is too large, it will cause poor contact of electrical components. In case of such road surface, please try to slow down or get off as well. Avoid using the motor start switch with the brake brake to avoid overloading the motor and damaging other components. In case of motor start-up and release, the vehicle is still energized. In this case, the electric door should be closed immediately and the pedal riding function should be used. The vehicle should then be sent to the professional maintenance department for inspection.

13. Although electric bicycles have good rainproof performance, please avoid direct sunlight and rain to prevent corrosion of the car body or rotating parts. When using in the rainy season or passing through the water pool or water, the water level cannot be higher than the center line of the axle. Prevent damage caused by water in the motor. Every other month, please check the front and rear forks, handlebars, flat fork shaft, rear shock absorbers, and fasteners. If any one of the consumers finds any looseness, please go to the local designated maintenance department. service. Please use lubricating oil to maintain the relevant transmission parts of the car body, such as: front axle, middle axle, flywheel, front fork shock absorber rotation fulcrum, etc., scrub every six months to one year, add butter or oil as needed.

Common faults and maintenance methods for electric tricycles

The maintenance of the electric tricycle includes checking whether all the screws and nuts of the whole car are strong, whether the control performance is good, whether the tire needs to be replaced, whether the mechanical system is good, whether the battery capacity is up to standard, and the brush motor is repaired once a year. The specific maintenance contents are as follows:

(1) Complete commissioning of the whole vehicle, check whether there is any hidden trouble in the electrical control circuit, whether the electrical connection line is damaged or not, and if it should be eliminated locally;

(2) Adjust the front and rear brakes to ensure that the brakes are flexible and reliable;

(3) Whether the steering of the handlebar is reliable, whether there is a phenomenon that the handlebar and the front fork slide against each other;

(4) Periodic inspection of the battery (check once a month in summer and every 2-3 months in winter) Whether the liquid level of the battery is below the marked line. If the plate is exposed, the distilled water should be replenished in time. (Be careful not to add acid, because each battery has adjusted the electrolyte concentration according to the ratio at the factory. Adding acid will destroy the existing acid-base balance, causing corrosion of the plates and affecting the battery life.

(5) When using the rear axle, pay attention to the gear oil in the rear axle gearbox. Afterwards, check the rear axle gearbox for oil leakage, seal gasket damage, lack of lubricating oil, replace the gasket in time, and replenish the lubricating oil.

(6) Gearbox, motor sprocket, chain regularly add lubricant, if the wear is serious, it should be replaced in time to avoid affecting the use.

(7) The whole vehicle bolts should be tightened once in a row to check for looseness or falling off, and appropriate anti-rust liquid to avoid screw rust and cause difficulty in maintenance during the life.

(8) The whole vehicle is clean and the test is clean.
