An integrated internally supported hub motor electric wheel-

Abstract

An integrated internally supported hub motor electric wheel is disclosed, and includes tyres, hubs, hub motor, -a honeycomb structure inn support body, a brake and a vibration damping mechanism-, wherein the hub motor comprises an outer rotor shell integrating a hub and a brake connecting disk, an outer rotor composed of a rotor yoke and a permanent magnet, an inner stator and a stator support frame, wherein the rotor yoke and the permanent magnet are attached to the inner side of the rim, and the brake connecting disk and the rim are fixedly connected by bolts; The hollow inner stator is connected with a suspension sleeve through a stator support frame, and the suspension sleeve is respectively connected with a knuckle arm and a wheel support shaft through an elastic element; The inner support is a sectional arc honeycomb structure, which plays a supporting and cushioning role under low pressure or zero pressure driving conditions. compared with that prior art, The invention has the advantages of simple and compact structure, high transmission efficiency, easy arrangement and installation, and the like, reduces the unsprung load mass, effectively improves the dynamic characteristics of the electric vehicle wheel, and embeds the inner support body, effectively avoids the influence of the road excitation on the performance of the hub motor under the low-pressure or zero-pressuredriving condition, and ensures the safe continuation of the deflated wheel.

Description

technical field [0001] The invention relates to an integrated internally supported hub motor electric wheel, which belongs to the technical field of electric vehicle power drive systems and safety wheels. Background technique [0002] Due to the increasingly prominent energy and environmental problems, electric vehicles have become the development direction of future automobiles due to their advantages in energy saving and environmental protection. In view of the unique advantages of electric wheel drive electric vehicles in chassis structure, transmission efficiency, and handling performance, It has attracted extensive attention from industry and academia. As one of the key technologies with the most development potential for new electric vehicles, the in-wheel motor drive mode integrates the wheel hub, motor, transmission mechanism and brake. However, how to arrange it reasonably in the limited internal space of the wheel highlights the importance of lightweight, integrate...
