What are the advantages of using in-wheel motor drive for electric vehicles?

1. A large number of transmission components are omitted to make the vehicle structure simpler
For traditional vehicles, clutches, transmissions, transmission shafts, differentials and even transfer cases are all essential, and these components are not only heavy, but also make the structure of the vehicle more complicated, and also require regular maintenance and The problem of failure rate. But the hub motor solves this problem very well. In addition to a simpler structure, vehicles driven by hub motors can achieve better space utilization, and the transmission efficiency is also much higher.
2. Folding can realize a variety of complex driving methods
Since the in-wheel motor has the characteristics of independent drive of a single wheel, it can be realized relatively easily whether it is front-wheel drive, rear-wheel drive or four-wheel drive. Full-time four-wheel drive is very easy to implement on a vehicle driven by a hub motor. At the same time, the in-wheel motor can achieve differential steering similar to that of a tracked vehicle through different rotation speeds or even reverse rotation of the left and right wheels, which greatly reduces the turning radius of the vehicle, and can almost achieve in-situ steering under special circumstances (but at this time the vehicle steering mechanism and The wear of the tires is greater), and it is valuable for special vehicles.
3. It is convenient to adopt a variety of new energy vehicle technologies
Many new energy models use electric drive, so hub motor drive also comes in handy. Whether it is a pure electric vehicle, a fuel cell electric vehicle, or an extended-range electric vehicle, the hub motor can be used as the main driving force; even for a hybrid vehicle, the hub motor can also be used as a booster for starting or rapid acceleration. One machine with multiple functions. At the same time, many technologies of new energy vehicles, such as braking energy recovery (that is, regenerative braking), can also be easily realized on in-wheel motor-driven models.
