The electric tricycle differential motor maintenance knowledge

Based on article

By differential motor brushless dc motor and differential (commonly known as the tooth package) :

: brushless dc motor is mainly composed of stator winding, rotor permanent magnet (tile) and position sensor (hall);

Differential: ability to make left and right driving wheels at different speed of rotation. Mainly by around half shaft gear, two planetary gear and gear rack.

Three, the electric differential motor common faults

3.1, differential sound, sound is divided into two kinds of voice:

3.1.1, shrill scream, commonly known as the noise is big, this exception is commonly gear clearance fit bad oil, gear oil shortage or metamorphic, which the fault should be in differential or replace gear oil;

3.1.2, gear ring, this kind of undesirable general for the processing of bad gear itself or by external knock against, replace the differential.

# 3.2, electricity JiSao friction (stator), which the fault should be replaced motor:

3.2.1, electricity JiSao hall after have a rumbling, can lead to not work properly, when turn don't turn, stop-and-go;

3.2.2, there will be a load force phenomenon, light can turn, but one plus load, and can't normal turn immediately.

3.3, the oil:

3.3.1, differential, operation

Four, replace the differential installation requirements:

4.1, motor and differential is strong and reliable installation, pay attention to the position of oil seal, see figure after the installation is complete;

4.2, rear axle and differential even meet with figure 2, figure 3, bolting, screw fastening, rear axle and differential joint close specific requirements, flexible rotation the same ring, bolts secure;
