Description
Technical field
The invention belongs to vehicle suspension technical field, more particularly to a kind of three mass suspension systems for chassis vibration damping
System.
Background technology
The reinforcement of the oil crisis and people's environmental consciousness of getting worse, the automobile industry as consumption of petroleum rich and influential family is not
The development of evitable concern electric automobile.Electric car is as a kind of Direct wheel drives vehicle, its compact-sized, transmission efficiency
Height, each Electric Motor Wheel is individually controllable, and dynamics Controlling is more flexible, is advantageous to improve traveling of the automobile under severe pavement conditions
Performance.Electric Motor Wheel turns into following most market potential and competitiveness with its Highgrade integration, high efficiency and light-weighted advantage
Organization plan.
In this new drive form, due to the introducing of wheel hub motor, vehicle nonspring carried mass dramatically increases, direct shadow
The ground connection performance to tire is rung, so as to cause vehicle safety and ride comfort to reduce, this is to restrict the type electric car to develop
One important problem, directly affects the popularization of Direct wheel drives vehicle.
A kind of new type of passive suspension containing used container is disclosed in patent CN105644289A, it is characterised in that:Including
Support spring, auxiliary damper, used container, main damper and secondary spring, the auxiliary damper are connected shape with used container
Into low-frequency vibration filter, the secondary spring is in parallel with main damper to form dither filter, the height
Frequency vibration filter is connected with low-frequency vibration filter and forms full rate vibrative filter；The full rate is vibrated
Filter device is in parallel with support spring, and the upper end of the parallel-connection structure is articulated with vehicle body, and lower end is articulated with wheel.The present invention can delay
Punching and decay high band, low-frequency range concave-convex road surface impact so that vehicle can adapt to full rate vibration road surface, can be effective
The riding comfort of automobile is improved, reduces influence of the road roughness to body of a motor car.
A kind of used container adjustable used shock absorber dress for holding coefficient in parallel with damping is disclosed in patent CN204955991U
Put, including conventional damper shock absorber working cylinder and hydraulic motor.Damping shock absorber working cylinder has a piston and piston rod, and piston is by liquid
Cylinder pressure is divided into epicoele and cavity of resorption, and normal open valve is fixed on piston, and aperture is provided with the upper lower wall of damped cylinder；Hydraulic motor both ends lead to
High-pressure hose and flow speed control valve is crossed respectively with two chambers above and below the shock absorber of perforate on wall to be connected.When the external force edge from vehicle body and ground
When shock absorber axial direction imposes on piston rod, piston moves along a straight line relative to cylinder body, and two chambers form pressure difference to shock absorber up and down, with
The change of pressure difference, flowing to the flow of the fluid of epicoele by cavity of resorption by normal open valve can be changed, and liquid is flowed to by flow speed control valve
The flow of pressure motor keeps constant, both obtains damping, realizes the used appearance adjustable feature of coefficient of used container again, and structure is tight
Gather, flexible arrangement.
Patent CN203666317U discloses a kind of Pendant Structure Of Vehicle containing used container.Based on new electromechanical analogy reason
By used case corresponding with capacitor in circuit element in mechanical organ is applied in vehicle suspension vibrating isolation system.
To avoid passive mechanical organ because bearing the problem of car body weight causes overload to fail, using parallel springs as architecture basics, propose
Used container and damped series, then the Pendant Structure Of Vehicle in parallel with spring element.It is of the present utility model simple in construction, do not improving
While car body weight, " empty inertia " effect of increase spring carried mass is realized, the ride performance that can improve vehicle is steady with manipulating
It is qualitative.By simulation analysis, with the vehicle suspension of such a structure, its ride comfort evaluation index vehicle body acceleration root-mean-square value,
Suspension moves stroke root-mean-square value, tyre dynamic load lotus root-mean-square value has reduced, and has certain application value.
Patent of the prior art can improve vehicle bottom to a certain degree mainly by designing different used structure of container above
Disk dynamics, but be not to be directed to because wheel hub motor adds unsprung mass problem.The power at used structure of container both ends is special
Property it is identical, to unsprung mass increase caused by ground connection property with smooth out sex chromosome mosaicism improvement it is limited and complicated.Because of traditional vehicle
Wheel be connected with suspension by bearing, only exist a rotary freedom, when wheel hub motor vehicle unsprung mass increase,
Wheel ground adhesion deteriorates with ride comfort, and vertical freedom degree is not present between the wheel of conventional truck and suspension, it is difficult to effectively inhales
Receive decay vibrational energy.
The content of the invention
It is an object of the invention to provide a kind of three mass suspension systems for chassis vibration damping, increase wheel hub motor and car
Vertical flexibility between wheel, improve the vehicle ride comfort as caused by wheel hub motor unsprung mass increase and grounding safety sex chromosome mosaicism.
The purpose of the present invention is achieved through the following technical solutions：
A kind of three mass suspension systems for chassis vibration damping, including sprung mass 1, spring 2, shock absorber 3, wheel hub motor
4th, bushing 5, unsprung mass 6 and tire 7, described spring 2 and shock absorber 3 are parallel between sprung mass 1 and wheel hub motor 4,
The outer layer of described bushing 5 is rigid layer 8, and internal layer is flexible layer 9, and the internal layer of bushing 5 is nested with unsprung mass 6 by bearing 10
The housing of wheel hub motor 4 on, outer layer is fixedly connected with the stator of wheel hub motor 4, and the tire 7 of unsprung mass 6 contacts with ground.
Further, the flexible layer 9 of described bushing is rubber layer.
Further, the outer surface of the rigid layer of described bushing 5 is provided with four bolts hole 11, by bolt hole 11 with
The stator of motor is fixedly connected.
The positive effect of the present invention is as follows：
1. the present invention bushing of increase with certain vertical flexibility between wheel hub motor and wheel, compared to prior art
Middle complicated used structure of container has simple in construction and saving suspension space advantage；
Asked 2. the present invention can improve the ride comfort caused by wheel hub motor increases vehicle unsprung mass with ground integrity
Topic, suspension other performances are further improved and improved, include the limit attachment of vehicle, the steering tracking on coarse bending road surface,
