The problem of above structure is present：Suspending cushion uses the vibration insulation structure of sandwich style, and it is single to buffer latitude, it is impossible to full
The big damping of sufficient electric car automobile starting moment low frequency and the demand of the small damping of high frequency, the larger impact of electric motor starting moment can be led
The excessive NVH requirements that can not meet motor and run at high speed under operating mode of actuating power assembly displacement.Meanwhile the suspension of compressor of air conditioner needs
Individually designed, take up space economy that is big, causing cost increase to have influence on electric automobile.
Explanation of technical terms：NVH refers to Noise (noise), Vibration (vibration) and Harshness (sound vibration roughness),
Because above three is appearance simultaneously and interwoveness in the mechanical oscillation such as automobile, therefore often puts them on and ground together
Study carefully, NVH is a global question for weighing automobile making quality, and it is experienced as most direct and most surface to user vehicle
's.
The content of the invention
It is an object of the invention to provide a kind of electrical vehicular power assembly suspension system, using bikini suspension system configuration,
Meet the big damping of electric car automobile starting moment low frequency from the stiffness curve in three directions, can effectively prevent electric motor starting moment compared with
Big impact is interfered caused by causing power assembly displacement excessive, meets the NVH requirements that motor runs at high speed under operating mode.
To achieve the above object, the embodiment provides following technical scheme：
A kind of electrical vehicular power assembly suspension system, including along the left mounting bracket of car direction of advance, right mounting bracket and rear overhang
Support is put, wherein, the left mounting bracket includes the first left mounting bracket 2, the second left mounting bracket 3, the second left suspension
Support 3 is connected with the front end of decelerator 10, and its upper end is excessively connected on left suspension bushing assembly 1 with the first left mounting bracket 2, and
It is lifted on vehicle body crossbeam assembly 12；The right mounting bracket includes the first right mounting bracket 5, the second right mounting bracket 6, described
Second right mounting bracket 6 is connected with motor assembly 9, and it is right outstanding that its upper end is excessively connected to first with right suspension bushing assembly 4
Put on support 5, and be lifted on vehicle body crossbeam assembly 12；The rear suspension bracket 8 is connected with the rear end of decelerator 10, its lower end with
Rear-suspending bush Assembly 7 is connected.
Further optimization, compressor of air conditioner 11 is integrated and is assemblied on the second right mounting bracket 6, therefore the vehicle is saved
Compressor of air conditioner suspends individually designed.
Preferably, the rear-suspending bush Assembly 7 is fixed on the suspension hold-down support on subframe assembly 13.
Preferably, the power assembly is made up of motor assembly 9 and decelerator 10.
In order to better meet the NVH requirements that motor runs at high speed under operating mode, it is preferred that left and right, the rear-suspending bushing
There are multiple bellows being independently molded at assembly liner.
Also meet the lightweight requirements of electric automobile while intensity is met, it is preferred that left and right, the rear-suspending branch
Frame assembly is cast aluminium workpiece.
The present invention has redesigned the structure arrangement of electrical vehicular power assembly suspension system, using bikini suspension system knot
Structure, wherein left and right mounting assembly are mainly carried caused by weight and ground excitation, the spontaneous excitation of power assembly of power assembly
Impact, vibrations, rear-suspending mainly carry torsional pulse and the excitation of power assembly.Meet from the stiffness curve in three directions electronic
The big damping of car automobile starting moment low frequency, the impact that can effectively prevent electric motor starting moment larger cause power assembly displacement excessive
Caused interference, there are multiple bellows being independently molded at left and right, rear-suspending bush Assembly liner, meet that motor is transported at a high speed
NVH requirements under condition of changing a job.Left and right, rear suspension bracket assembly is cast aluminium workpiece simultaneously, had both met while intensity or had expired
The lightweight requirements of sufficient electric automobile.
