Embodiment Construction

[0010] The specific implementation of the wheel hub magnetic suspension support driven electric vehicle of the present invention will be described below with reference to the accompanying drawings.

[0011] see figure 1 , the wheel hub magnetic suspension support drive type electric vehicle of the present invention includes front and rear hub bearingless motor support drive systems (ie, front hub bearingless motor support drive system and rear hub bearingless motor support drive system) and a drive system for detecting and controlling the front , The detection and control system of the bearingless motor in the rear wheel hub bearingless motor support drive system. The front and rear wheel hub bearingless motor support drive systems each include a support shaft 6, which is fixed on the vehicle frame 8, and the two ends of the support shaft 6 are symmetrically arranged with a wheel hub 5, a radial bearingless motor 1. The speed-regulating clutch 2 and the axial bearingless moto...

Abstract

The invention discloses a hub magnetic suspension supporting driven electric automobile, which comprises front and rear hub bearing-free motor supporting driving systems and a detection and control system for detecting and controlling bearing-free motors in the front and rear hub bearing-free motor supporting driving systems. The front and rear hub bearing-free motor supporting driving systems respectively comprise a supporting shaft (6), and the supporting shaft is fixed on a frame (8); and a wheel hub (5), a radial bearing-free motor (1), a speed adjusting clutch (2) and an axial bearing-free motor are symmetrically arranged at two ends of the supporting shaft. Through the hub magnetic suspension supporting driven electric automobile, no friction and no abrasion support between the wheel hub and the frame is realized by a magnetic suspension technology; and the wheel hub is directly driven to rotate by electromagnetic torque, so that a transmission chain is shortened, the driving efficiency is improved, the energy consumption is remarkably reduced, and the power performance of the electric automobile is improved.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to an electric vehicle driven by a hub magnetic suspension support. Background technique [0002] With the development of the global economy, the consumption of oil is increasing day by day. As a non-renewable resource, oil is becoming increasingly scarce. As the main means of transportation in the city, such as public transport vehicles, taxis and private vehicles, which circulate in the city, it not only consumes a large amount of oil energy, but also emits a large amount of harmful gases due to the extensive use of oil, causing serious damage. Environmental pollution is harmful to people's health. If these bad problems are not solved in time, it will bring invisible harm to the work, study and life of urban residents, and hinder the healthy development of urban material civilization. Therefore, electric vehicles are increasingly popular as alternative transportation tools for fuel vehicles...
