Advantages of wheel hub motors:
Advantage 1: Omitting a large number of transmission components makes the vehicle structure simpler
Advantage 2: Can achieve multiple complex driving modes
Due to the independent driving characteristics of a single wheel, wheel hub motors can be easily implemented in front wheel drive, rear wheel drive, or four-wheel drive forms. Full time four-wheel drive is very easy to implement on vehicles driven by wheel hub motors.
Disadvantages of wheel hub motors:
Although the overall quality of the vehicle has significantly decreased, the unsprung quality has greatly improved, which will have a huge impact on the handling, comfort, and suspension reliability of the vehicle.
2. Cost issue, the high conversion efficiency and lightweight four-wheel hub motor have high costs.
3. Reliability issues: Placing a precision motor on a wheel hub can lead to long-term severe up and down vibrations and harsh working environments (such as water and dust), which can cause malfunctions. It is also important to consider that the wheel hub is a vulnerable part in car accidents and has high repair costs.
4. The issue of braking heat and energy consumption is that the motor itself generates heat. Due to the increased mass under the spring, the braking pressure is greater and the heat generation is also greater. Such concentrated heat generation requires high braking performance.
