Embodiment Construction

[0010] The specific implementation of the magnetic levitation electric vehicle of the present invention will be described below in conjunction with the accompanying drawings.

[0011] The magnetic levitation electric vehicle of the present invention mainly utilizes magnetic levitation and bearingless motor technology to suspend the vehicle body, so that the semi-axis that fixes the wheels supports the vehicle body without friction and wear, and drives the semi-axis to rotate to drive the wheels to roll along the ground.

[0012] Such as figure 1 As shown, the maglev electric vehicle includes a rear wheel maglev support drive system, a front wheel maglev support system and a detection control system. The rear wheel magnetic suspension support drive system includes an axial magnetic suspension rear differential 1, a dynamic magnetic suspension bearing 2 (that is, a bearingless motor), a rear governor clutch 3, a rear half shaft 4 and a rear wheel 5 fixed on the rear half shaft ...

Abstract

The invention discloses a magnetic suspension electric automobile which comprises a rear wheel magnetic suspension bearing driving system, a front wheel magnetic suspension bearing system and a detection control system, wherein the rear wheel magnetic suspension bearing driving system comprises an axial magnetic suspension rear differential (1), a power magnetic suspension bearing (2), a rear speed governing clutch, a rear semiaxis and a rear wheel; the front wheel magnetic suspension bearing system comprises an axial magnetic suspension front differential (6), a radical magnetic suspension bearing (7), a front speed governing clutch, a front semiaxis and a front wheel; the detection control system comprises a controller (8) and a sensor. The magnetic suspension electric automobile realizes no friction and no abrasion bearing between the semiaxis and the frame, and directly drives the semiaxis to rotate so as to drive the wheels through an electromagnetic torque, shortens a transmission chain, and improves the drive efficiency; therefore, the energy consumption is obviously reduced, and the power property of the electric automobile is improved.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a magnetic levitation electric vehicle. 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. attention. [0003] H...
