Wheel motor is the key technology for the development of electric buses
Wheel hub motors are a key technology for the development of electric buses. Wheel motors help bus manufacturers adapt to the changes brought about by the development of electric power systems. They integrate electric power systems and braking systems, bringing a new technical solution; wheel motor drive technology can be deployed on various new energy vehicles. Of great use. Whether it is a battery electric vehicle, a fuel cell electric vehicle, or an extended-range hybrid electric vehicle, an in-wheel motor can be used as the main driving force; the use of wheel motors enables the redesign of public buses to make them lighter, more compact, and more spacious become possible.
In the new energy era, electric vehicles have become the darling of the market, and the driving form of electric vehicles is not single. In fact, hub motors are very common. Electric bicycles are this type of drive. The motor is integrated inside the wheel, which sounds like a perfect drive solution. The working principle of the wheel motor is a permanent magnet synchronous motor, while the wheel motor and the wheel motor refer to motors that are installed in different locations on the vehicle. To put it bluntly, the wheel hub motor is a motor designed to integrate the "power system, transmission system, and braking system" of the car.
The technical principle of the wheel hub motor is to place the motor assembly integrated with the reducer directly in the wheel hub, and the four wheel motors directly drive the four wheels. Compared with traditional electric vehicles, wheel motor technology eliminates the need for differentials, half shafts and even secondary transmission devices, which allows it to be flexibly arranged in the wheels of various electric vehicles and directly drive the wheel hub to rotate. Compared with traditional centralized drive methods such as internal combustion engines and single motors, the technical advantages and characteristics in power configuration, transmission structure, control performance, energy utilization, etc. are extremely obvious.
Since the wheel motor has the characteristic of independent driving of a single wheel, it can be relatively easily implemented 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 an in-wheel motor. At the same time, the wheel hub motor can realize differential steering similar to a tracked vehicle through the different speeds of the left and right wheels or even reverse rotation, greatly reducing the turning radius of the vehicle. In special circumstances, it can almost achieve in-situ steering (but at this time, the vehicle steering mechanism and Tire wear is greater) and is valuable for special vehicles.
For traditional vehicles, clutches, transmissions, drive shafts, differentials and even transfer cases are all essential. Not only are these components heavy in weight and making the structure of the vehicle more complex, they also require regular maintenance and Failure rate problem. But the hub motor solves this problem very well. In addition to having a simpler structure, vehicles driven by wheel hub motors can achieve better space utilization, and the transmission efficiency is also much higher.
Many new energy vehicles use electric drive, so wheel hub motor drive comes in handy. Whether it is a pure electric vehicle, a fuel cell electric vehicle, or an extended-range electric vehicle, a wheel motor can be used as the main driving force. Even for hybrid models, the wheel motor can be used as a boost when starting or accelerating rapidly. It is really a multi-purpose machine. At the same time, many technologies of new energy vehicles, such as braking energy recovery (i.e. regenerative braking), can also be easily implemented on wheel motor-driven models.
