The invention relates to a motor suspension. A core tube is arranged in a sheath in a hollow columnar shape or a hollow drum shape, and then the sheath, the core tube and resonance mass blocks which are arranged in the sheath and evenly distributed around the core tube are bonded into a whole through a rubber body, so that high-frequency vibration and high-frequency howling noise, especially high-frequency vibration and high-frequency howling noise 800 Hz or above, generated when an electric automobile driving motor suspended on a frame works can be effectively absorbed and blocked, comfortable vehicle using experience can be given to a driver and passengers of an electric automobile, driving fatigue can be relieved, and traveling safety can be ensured. According to the motor suspension, aresonant structure is formed by implanting the resonance mass blocks into the rubber body, and through self-vibration of the resonant structure, high-frequency hardening of the rubber body can be effectively relieved, the high-frequency dynamic stiffness of the rubber body can be reduced, so that the high-frequency vibration and high-frequency howling noise of the driving motor can be better lowered; and the motor suspension can be further applied to absorption and blocking of high-frequency vibration and high-frequency howling noise from different noise sources such as other motors and air compressors.

    一种电机悬置,通过在空心柱状或空心鼓状护套内设置芯管、再通过橡胶体将护套、芯管、以及设置在护套内部且均匀分布在芯管周围的共振质量块粘合形成一个整体,能够有效吸收和阻断悬置于车架上的电动汽车驱动电机工作时发出的高频振动和高频啸叫噪声,特别是800Hz以上的高频振动和高频啸叫噪声,给予电动车驾乘人员舒适的用车体验,减轻驾乘的疲劳,保证行车的安全。本发明通过在橡胶体中植入共振质量块组成一个共振结构,通过这种共振结构的自振动,可以有效减弱橡胶体的高频硬化,降低其高频动刚度,从而更好地降低驱动电机的高频振动和高频啸叫噪声;本发明还可用于其他电机、空压机等不同噪声源高频振动和高频啸叫噪声的吸收和阻断。
