The importance of electric tricycle harness

Played a harness connected to the power brake and turn the role of the controller , it will cause a lot of problems of poor quality . As big line of fire , turn the brake failure, the car lost control and other serious problems. Why should lock wire bold ? Battery to lock and lock to the wire between the square of the controller is not enough, the wire will be hot , especially in the summer there will be lines melted skin , short Electric Bicycles circuit the fire . Since this section of the wire to form a longer resistance , not all of the current for the motor acting, a considerable part of the wire into a fever , so the car will appear boring and continued short trip mileage and so on. 9 , the relationship between electric tricycle brake , turn to the role and the harness can not brake controller choke off easily burn . Sometimes harness problems will make you suspect that the damage to the brake switch , such as switch between the connection to the controller , if the 5 volt line or Electric scooters signal line not General car does not go ; ground not General coaster ; brake lever to the controller harness between the signal line or the ground , such as disconnecting the brake failure. Brush motor damage type column : Brush masticate , copper head blown, copper head coke, copper head even burn , burn wire shorted shorted wire and shell , enameled blown, burned wires connected to the input , the input wire mill off .

Fault analysis of electric vehicles

( 1 ) insufficient tire pressure will increase tire friction and road surface , thereby reducing Continued mileage ; handlebar rotation flexibility will enable to reduce the impact of riding comfort and safety. Should be less pressure to replenish pressure, tire pressure should be in accordance with the provisions of the "electric bicycle manual " in the recommended tire pressure or surface pressure .
( 2 ) handlebar rotation is not flexible, catching point when stiff or tight spot , should be timely lubrication or adjustments. Lubrication general use butter , calcium or lithium grease ; Electric Bicycles adjustment , release fork lock master , rotating fork stop , when the handlebars turn the flexibility to meet the requirements , you can lock nut locking fork .
( 3 ) the flexibility of front and rear wheels turning bad , will increase the rotational friction, increase power consumption , thereby reducing Continued mileage . Therefore, once the fault should be timely lubrication and maintenance , lubrication general use butter , calcium or lithium grease ; If the shaft skin fails, you can replace the ball or shaft skin , if the electrical fault should go to a professional repair unit maintenance.
( 4 ) circuit inspection, turn on the power electric scooters switch , check the circuit is smooth, solid and reliable connectors are plugged , whether the fuse is working properly, especially connected with the output terminal of the battery cables are secure and reliable. Found fault should be immediately removed .
( 5 ) before the trip , check the battery charge , according to the judgment of the battery power is sufficient mileage to travel . If the power is not sufficient manpower should be supplemented by appropriate riding, avoid battery undervoltage work .
( 6 ) It should also be checked before traveling the working conditions of the motor. Starter motor and adjust its speed to observe and hear the motor running , if abnormal, should be timely maintenance.
( 7 ) should be checked electric lights, horn and other former bicycle use , especially at night travel. Headlights should be bright, light should generally fall in the range of 5-10 meters in front of the front ; horn should sound loud, not hoarse ; turning lights should be flashing normal , indicating normal steering , lights flicker frequency of 75-80 beats / min ; Meter display should be normal .
( 8 ) should be checked before traveling all the major fasteners are tightened , such as the horizontal tube , the riser, saddles, saddle tube , front, rear, bottom bracket , lock nut , pedal and other fasteners should not loose fasteners loose or fall off if there should be tightened or replaced promptly . The recommended torque fasteners generally: the horizontal pipe, the riser, saddles, saddle tube , front wheel , pedal to 18N.m, mother and rear wheels to lock axis 30N.m.
