During the long-term use of the battery level vehicle, the deformation of the front wheel hub of the flat car or the inconsistency of the number of tire bolts will be affected by various factors.
Inconsistent front spring stiffness, frame deformation, rivet loosening or front axle deformation.

The low-voltage flat end voltage is less than 10% of the rated voltage, and the starting torque is too small to operate normally and cannot operate normally. During the test, the input voltage of the horizontal vehicle is measured with a multimeter or voltmeter.
Gearbox failure: stop inspection, first determine whether the reducer or bearing is lubricated, whether to replace the lubricating oil regularly. If lubrication is not required, the reducer will not only produce excessive noise, but also cause excessive wear or damage to the gears and bearings.
