Abstract
In the past few decades, people have discovered the importance of electric vehicles, as well as the necessity of energy conservation and environmental protection, and electric passenger cars have become more and more popular in daily life.
As time goes by, oil resources are increasingly scarce and environmental problems are becoming increasingly serious. Against this background, the research on energy-saving and environment-friendly electric vehicles has received widespread attention and attention, showing great development potential and application prospects.
My guess is that in the next few decades, people will be using electric cars as the main force in the automobile industry, so it will be very important to realize the electrification and move towards the new electric drive.
This paper will study and design the wheel hub motor drive structure along the way of electric vehicle wheel hub drive, so as to improve its electricization, integration level and spatial layout integrity.
The hub motor is the main component of its power output, and its structure and performance have strict standards. At the same time, the installation of hub motor and brake makes the composite electric structure complicated. In addition, the deceleration and torque increasing mechanism assembled with hub motor needs scientific design, so as to meet the actual demand and really play the expected role.
This topic mainly studies the performance standards of driving motors under various driving structures for electric vehicles, and completes the introduction of relevant driving principles and dynamic analysis.
According to the ordinary car body structure and its working with hub motor requirement, clear the motor type and some of the key performance parameters, design of the traditional braking system, the whole structure is relatively new, have good practical value, can not only to meet the needs of social development, but also can bring more convenience to the public, the practical significance is significant.
Key Words:Compound electric wheel; Hub motor; Permanent magnet synchronous motor; Planetary gears; Disc brake
