The invention discloses a power assembly magnetic suspension structure and an electric automobile. The power assembly magnetic suspension structure comprises a fixed magnetic part, a movable magneticpart, a limiting part, a supporting part and a base. The fixed magnetic part is fixed on the base; the movable magnetic force part and the fixed magnetic force part are oppositely arranged in the samemagnetic pole, and the movable magnetic force part is connected with the supporting part; the supporting part is used for supporting the power assembly; and the limiting part is used for limiting therelative position between the fixed magnetic part and the movable magnetic part. The power assembly can be suspended through magnetic forces generated by homopolar repulsion between the fixed magnetic force part and the movable magnetic force part, large-amplitude and low-frequency vibration is absorbed and isolated, and the driving comfort is improved; and ultrahigh-frequency and small-amplitudevibration can be absorbed and isolated by utilizing the characteristic of high magnetic response speed.
本发明公开了一种动力总成磁力悬置结构及电动汽车,包括固定磁力部、活动磁力部、限位部、支撑部和底座;所述固定磁力部固定于所述底座上;所述活动磁力部和所述固定磁力部呈同磁级相对设置,所述活动磁力部连接所述支撑部;所述支撑部用于支撑所述动力总成;所述限位部用于限制所述固定磁力部与所述活动磁力部之间的相对位置。本发明既能够利用固定磁力部与活动磁力部之间同极互斥产生的磁力使动力总成悬空,对大振幅、低频的振动进行吸收和隔离,增加驾驶舒适性;又能够利用磁力响应速度快的特点对超高频、小振幅的振动进行吸收和隔离。
