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