Description
Technical field
The present invention is on a kind of high-end pure electric sedan suspension system.
Background technology
Suspension system is that support, the device of spacing and vibration isolation effect are played to power assembly.Suspension system is by power assembly
It is connected on vehicle body, and limits the static state and dynamic position of power assembly；The vibration that power assembly can be isolated simultaneously is delivered to
Vehicle body, can also reduce from outside various vibration interferences..
Cooperate with external certain Chevron Research Company (CRC), the high performance B+ grades of high-end pure electric sedan of exploitation, max. speed 150km/h,
Continual mileage is up to 330km.Product structure feature is that front deck arrangement space is larger, and left and right vehicle frame spacing is larger, applies compact
Small-sized, high performance centralized electrical vehicular power assembly, be made up of motor and decelerator, be arranged in front deck.Compared to biography
System internal combustion engine car and small-sized pure electric vehicle of riding instead of walk, the power drive system volume of this centralization are smaller, by suspension system
When being connected to vehicle frame, the structure to suspension system proposes new challenge and requirement.
The function of powertrain mounting system and arrangement brief introduction：Powertrain mounting system major function is to carry dynamic
The weight of power assembly, the displacement in limitation power assembly motion process, isolates the vibration of power assembly, and meeting vehicle comfortableness will
Ask.At present, the suspension system of most internal combustion engine cars and electrocar is all bikini, i.e., left and right, rear three-point suspension,
Power assembly (engine and gearbox or motor and decelerator) is fixed on the left and right vehicle frame of vehicle body by left and right suspension
On, rear-suspending connects gearbox (or decelerator) and fore sub frame, undertakes the moment of torsion of power assembly output.
Because such high-end pure electric sedan power assembly differs greatly with car, without engine and gearbox, take and generation
Power assembly be made up of motor and decelerator, and power assembly small volume, light weight, and peak value output torque becomes
Greatly, up to 330Nm.The position of the limitation of driven moving axis position, motor and decelerator below vehicle frame, power assembly
Compared with " remote " with a distance from left and right vehicle frame, the left suspension and right suspension existing structure that traditional vehicle is used can not meet fixed electric motor car
The demand of power assembly, and rod-pulling type rear-suspending cannot undertake the output of motor high pulling torque, need to again develop suspension system.
The content of the invention
The present invention provides a kind of high-end pure electric sedan suspension system, its respectively with electrical vehicular power assembly and vehicle frame phase
Even, it includes：In the left mounting assembly that positive triangle is arranged, right mounting assembly and rear-suspending assembly, and the electrical vehicular power is total
Into including：Motor and decelerator；The left mounting assembly includes：It is soft with the left suspension that the left longitudinal beam of the vehicle frame is connected
Pad, and the left mounting bracket being connected with decelerator；The right mounting assembly includes：The right side being connected with the right longitudinal beam of the vehicle frame
Mounting bracket, and the right suspending cushion being connected with the motor；And the rear-suspending assembly includes：With the horizontal stroke of the vehicle frame
To the rear-suspending cushion that beam is connected, and the rear suspension bracket being connected with the rear end of the electrical vehicular power assembly.
The novel suspension system is left and right, rear-suspending is distributed in electrical vehicular power assembly periphery, constitutes equilateral triangle structure,
And power assembly is exported when in one plane, effectively having decayed electric motor car because of starting with electrical vehicular power assembly barycenter distribution
The power assembly oscillating quantity of the big generation of moment of torsion problem bigger than normal.
