Abstract

The invention relates to an electric automobile power assembly suspension system which comprises a right suspension (40), a left suspension (20), a rear suspension (70), a crossbeam (30) and a power assembly (80). The power assembly (80) is connected to the position below the crossbeam (30). The left end and the right end of the crossbeam (30) are connected to an automobile body left longitudinal beam (10) and an automobile body right longitudinal beam (50). The left suspension (20) and the right suspension (40) are connected to the crossbeam (30). The bottom ends of the left suspension (20) and the right suspension (40) are connected to the power assembly (80) through second supports (90). The rear suspension (70) is connected to the power assembly (80) through a first support (60), and the other end of the rear suspension (70) is connected to an auxiliary automobile frame of an automobile. The electric automobile power assembly suspension system is simple and reliable in structure, reasonable in arrangement, good in technological feasibility, simple and reasonable in installation and assembly and excellent in performance, the weight can be reduced by about 20%, and cost can be saved by about 25%.

Description

[0001] [technical field] [0002] The invention relates to the technical field of automobile power systems, in particular to an electric vehicle power assembly suspension system. [0003] [Background technique] [0004] The powertrain suspension system is a component that installs the powertrain to the body and frame of the car. The powertrain mounting system supports the powertrain, isolates the vibration and noise of the powertrain from being transmitted to the passenger compartment, reduces the vibration and noise of the powertrain, and manages the force and motion displacement of the powertrain under various working conditions. Provides good NVH performance and drivability for the driver and passengers. At present, there is a contradiction between customers' higher and higher requirements for automobile vibration and noise performance, and the requirement for automobile enterprises to improve technology and increase costs. At the same time, due to fierce competition in th...
