How to turn on the electric sightseeing bus?

Abstract: Electric sightseeing bus is an environment-friendly electric vehicle developed for tourist attractions, amusement parks and large parks. The driving speed of electric sightseeing bus is much slower than that of fuel-powered motor vehicles, which is one of the reasons why this car can't drive on the road. Many people report that when using electric sightseeing bus, its running speed is often slower than the normal running speed. What is the reason for this? How to turn on the electric sightseeing bus? The following small series is announced for everyone. First, how to drive the electric sightseeing bus?

Operating steps that must be followed when driving the belt drive:

1. First, insert the key into the power switch and turn it to the ON position.

2. Press the green part of the direction selection switch to the forward position.

3. Release the parking brake, press the clutch pedal, adjust the shift lever to low gear (1 or 2), release the clutch, press the accelerator pedal evenly, and start the vehicle.

4. When parking, release the accelerator pedal and slowly press the brake pedal. When the vehicle stops, pull up the parking brake.

Operating steps that must be followed when driving an electric sightseeing bus without transmission:

1. Insert the key into the electric lock switch and turn it to the ON position.

2. Press the green part of the direction selection switch to the forward position.

3. Release the parking brake and press the accelerator pedal evenly to start the car. The lower the accelerator pedal, the higher the speed.

4. When parking, release the accelerator pedal and slowly press the brake pedal. When the vehicle stops, pull up the parking brake.

Second, the reason why the speed of electric sightseeing bus suddenly slows down.

1, abnormal battery voltage, insufficient power.

When the driving speed of electric sightseeing bus is slow, it is necessary to check whether the battery voltage is normal or not, and whether it is caused by insufficient power. If it is due to lack of motivation, it should be replenished in time.

2. The motor is severely demagnetized

When using an electric vehicle, the motor load is too large, which will gradually weaken the magnetic force of the motor until the magnetic steel is demagnetized; If it is in the case of strong vibration or high temperature, the motor will also demagnetize; Some motors are flooded, causing rust to "break" the surface of the magnet and quickly "eat" the magnet. Solution: Replace the high-quality motor.

3. The problem of torsion

The inside of the handle consists of a magnet, a spring and a Hall element. When there is a foreign object or a spring problem in the handle, the motor speed will slow down and the speed of the electric vehicle will decrease. Solution: Replace the transmission handle and firmly connect the connector.

4. Internal fault of the controller

The controller is the "brain" of the electric vehicle, which controls forward, backward and stop. It distributes current to drive the motor. The greater the current, the faster the speed. If the controller fails, the speed will naturally slow down. In addition, the power mismatch between the controller and the motor will also lead to slower speed. Solution: Replace the matching controller.

5, third gear speed change fault

Through the controller to speed up the shift frequency to achieve shift, increase the output current and increase the motor power, which can be divided into slow gear, fast gear and ultra-fast gear. When the shift switch is placed in the common gear, the speed of the shift switch is obviously slower than that of the overspeed gear. Solution: Replace the damaged shift switch.

6, brake failure

Brake failure includes over-tightening, brake rebound, brake pad falling off and so on. When the wheel friction increases, the speed naturally slows down. Solution: Repair the brake device.

7. Mechanical failure

No matter the front wheel or the rear wheel of an electric vehicle, there should be no rolling resistance, which will hinder the operation of power. Forgot to pull the handbrake, large bearing clearance, insufficient tire pressure and other mechanical failures. , increase wheel friction and slow down the speed. Solution: repair, find out the specific mechanical failure and find out the correct medicine.

8. Speed limiter

Because the current standard for electric vehicles is the old national standard of 1999, one of the requirements is that the maximum speed should not exceed 20 yards per hour, otherwise it will exceed the automobile standard and it will be impossible to obtain a license plate. In the event of a traffic accident, the manufacturer will bear the responsibility. Therefore, many manufacturers will set a speed limit line when new cars leave the factory. Solution: Cutting this line can improve the speed.

9. The electric car is overloaded

The speed and weight of electric vehicles are closely related to their speed and weight. When the load is loaded, the friction between the tire and the ground increases. If the load exceeds the standard requirements, there will be no problem for the time being, but the speed will not get higher and higher. Overload will seriously damage the motor and it is difficult to recover. The solution is to replace the high-quality motor and pay attention to the future load.
