7. The rim of the electric car is erratic, sometimes to the left and sometimes to the right.
(1) The clearance of the rolling bearing of the front axle or the rear axle is too large → Adjust the clearance of the rolling bearing. To
(2) The elasticity of the spokes is different, and it is fixed at a certain position by fluttering → adjust the elasticity of the spokes. To
(3) The steel balls in the front axle or the rear axle are damaged or have different sizes → replace the steel balls. To
Eight, the front wheel of the electric vehicle is driven to the left or right
(1) The front axle nut is loose → adjust the front axle rolling bearing clearance, and tighten the front axle nut. To
(2) Relative movement between the handlebar and the front fork due to collision or loosening of the core bolt → Tighten the core bolt.
(3) Deformation of the front fork riser or front fork leg → Correct the front fork riser or front fork leg. If the fault cannot be eliminated, replace the front fork. To
9. The front or rear wheels of the electric vehicle shake
(1) The front wheel is shaking indefinitely on the front fork and the rear wheel in the frame fork or vertical fork → the front axle or rear axle nut is loose and tightened. To
(2) The rolling bearing assembly of the front axle or the rear axle is too loose → adjust. To
10. The front or rear wheels of electric vehicles are skewed
During riding, the front wheel or the rear wheel does not rotate in the normal position, but deviates in a certain direction, and the front or rear axle nut is loose → tighten. To
11. The front fork of the electric vehicle shakes
Lift the handlebar with both hands and feel loose → the front fork rolling bearing gap, loosen the lock nut, screw up the block to the proper position, and then tighten the nut. To
12. Loosening of the central axle of the electric vehicle
Holding the left and right cranks, the bottom rollers appear to be loose up and down, left and right, and the matching of the bottom roller bearings is too loose → adjust the gap between the bottom roller bearings. To
13. Automatic locking of electric vehicle's central axle
The bottom bracket roller cannot rotate → adjust the gap of the bottom bracket rolling bearing. To
14. Crank rotation of electric vehicle
(1) When advancing forward, the crank sometimes rotates forward automatically. Too much oil on the flywheel, make the flywheel jacket and core rotate together → ① Pour the car to the left, pour kerosene into the gap between the flywheel jacket and the wire block and reverse the chain to clean the dirt inside the flywheel. ② Remove the flywheel to clean the internal dirt. To
(2) The wheel rolling bearing is too tight → adjust the flywheel rolling bearing. To
15. The saddle of the electric vehicle rotates up and down
Turn the head of the saddle up or down, the clamping nut of the saddle becomes loose → After leveling the saddle, tighten the clamping nut of the saddle with a wrench.
16. Deflection of the saddle of the electric vehicle
The saddle deflects horizontally to the left and right, and the rear joint bolts and nuts of the frame are loose → After straightening the saddle, tighten the rear joint bolts and nuts of the frame. To
Seventeen, electric vehicle clamp brake failure
(1) The brake shoe is too far away from the rim → adjust the gap between the brake shoe and the rim. To
(2) The wire rope is broken or broken → replace with a new wire rope sleeve. To
(3) The wire rope and the wire rope sheath are stuck → ①Clean up the sand and other debris stuck on the wire rope. ②Inject oil into the steel wire rope and wire rope sleeve for lubrication. To
(4) The rope tightening screw is loose → After adjusting the gap between the brake shoe and the rim, tighten the tightening rope screw. To
(5) Wire rope extension → loosen the rope tightening screw, adjust the distance between the brake shoe and the rim, and tighten the tightening rope screw. To
18. The electric vehicle battery is full but the two red lights will go out under load
(1) The output voltage of the electrical appliance is too low → troubleshoot the fault according to the charger repair method. To
(2) The battery charging time is short → recharge to extend the charging time. To
(3) The capacity of the battery pack or its single unit has decreased → troubleshoot the fault according to the battery box repair method. To
(4) The electrode is damaged or the contact is poor → replace the electrode.
