Abstract

The invention discloses a power assembly suspension and a vehicle comprising same. The power assembly suspension comprises a rubber body, a sensor, a first magnetic component, a second magnetic component and a controller; the interior of the rubber body is provided with an accommodation chamber; the rubber body is provided with a power assembly connecting structure and a frame connecting structure; the sensor is arranged between the rubber body and the power assembly connecting structure; the sensor comprises a pressure sensor and or an acceleration sensor; the first magnetic component and the second magnetic component are respectively fixed on the wall of the accommodation chamber; at least one of the first magnetic component and the second magnetic component is an electromagnet; the controller is connected with the sensor and the electromagnet. The power assembly suspension is simple in structure and small in size, adaptively adjusts parameters such as the self-stiffness according to the vibration condition of an engine to adapt to the vibrational frequency of the engine and accordingly well attenuates the engine vibration and improves the damping effect.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power assembly mount for a vehicle and a vehicle with the power assembly mount. Background technique [0002] Powertrain mount refers to the elastic support between the vehicle powertrain (including engine, clutch, transmission, etc.) and the frame. The main function of the powertrain mount is to support the powertrain while isolating the vibration from the engine to the frame. [0003] Existing powertrain mount structures are generally classified into rubber mount structures and hydraulic mount structures. The structure of the rubber mount is simple, the cost is low, and the high-frequency dynamic stiffness of the rubber mount is greater than the low-frequency dynamic stiffness, and it has the characteristics of large stiffness and large damping, so that the rubber mount has a good low-frequency vibration isolation effect, but its high The high-frequency vibration isolat...
