Abstract

The invention relates to an electric automobile power assembly suspension device and an electric automobile. The invention belongs to the field of electric vehicles, the device comprises a bracket, areduction gearbox front suspension bracket and a motor suspension bracket, elastic pieces used for sound insulation and vibration reduction are arranged at a joint of the left suspension fixed supportof the bracket and the reduction gearbox front suspension bracket and a joint of a right suspension fixed support of the bracket and the motor suspension bracket respectively. The device is simple instructure, and the vibration isolation and noise reduction performance of the power assembly, the riding comfort of a vehicle and the operation stability of the power assembly are improved through the buffering effect of the elastic pieces; the electric automobile comprises an automobile body, the power assembly and the power assembly suspension device, the structure is simple, transmission of noise into a compartment and transmission of vibration into the power assembly are reduced, therefore the riding comfort of the automobile is improved, and the weight of the electric automobile is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an electric vehicle power assembly suspension device and the electric vehicle. Background technique [0002] With the increasing shortage of energy sources and people's increasing emphasis on environmental protection, it is a trend for electric vehicles to replace traditional internal combustion engine vehicles. The powertrain is an important part of electric vehicles, and the powertrain mainly includes motors, reducers, motor controllers, etc. used to drive electric vehicles. Compared with the motors used in traditional industries, the driving motors of electric vehicles have a wider range of speed and torque. However, the driving motor generates severe noise in a specific working area, especially in the high-load and high-speed area; the noise is transmitted to the cabin by installing the powertrain on the electric vehicle and the frame to reduce the nois...
