The present invention is released, is not intended to limit the present invention, can realize that the product of said function belongs to equivalent substitution and improvement, be all contained in
Within protection scope of the present invention.Specific method is as follows：
A kind of distance express delivery car unsteadiness of wheels data system of the present invention, it is characterised in that：The system is included as top
Express delivery car nave boss administrative center and several point of administrative center being attached thereto, be at least connected with one below point administrative center
Reception device and a storage device, the road condition analyzing device and wheel data of reception device respectively with being on express delivery car
Device wireless connection；Wherein express delivery car nave boss administrative center function includes：For receiving the data message of road condition analyzing device simultaneously

Receive the warning information from road condition analyzing device and make respective handling；Filled for setting up with the wheel data on express delivery car
Wheel data device on the contact put, processing express delivery car wants the solicited message at the automobile-used family of summation process express delivery；In addition, road conditions
Wheel data device and express delivery car on road conditions application subsystem connection of the analytical equipment also and in point administrative center, express delivery car
On wheel data device between also employing wireless be connected：Express delivery car nave boss administrative center, which provides, meets general-purpose interface specification
SDK interfaces, including：User authentication mandate interface, video steaming interface, double-directional speech interface, cradle head control signaling interface, report
Alert signaling interface, video file calling interface；The relation that wheel data device is used between road conditions and wheel, with respect to roadbed pressure
Influence of the power to express delivery car time-varying rigidity, analyzes change of the tri- direction relative rigidity luffings of wheel x, y, z with roadbed pressure,
To wish express delivery car working environment in rural area is changeable, operation type it is various in the case of, can remotely reflect road conditions, to meet it
To the demand of different road conditions.When express delivery car is in soil-trip, roadbed applies 500N dead load in certain orientation, and wheel hub turns
Speed is 20r/min.When to roll wheel pretightning force be 800N, left end roll tri- directions of wheel x, y, z relatively not variation luffing with
Rotate the situation of change of number, three directions keep stable after variation luffing declines rapidly relatively, variation is not with rotating number
Situation of change, it can be seen that roll wheel it is constant degree with rotate number increase and increase.Pretightning force is to rolling wheel time-varying
The not influence of variation, if roadbed applies 500N dead loads in y directions, rotating speed is 20r/min, and car is 8 by forwarding dynamic number.
Left end roll wheel x, y, z tri- directions relatively not variation luffing with the situation of change for rolling wheel pretightning force.When gradually increasing
Added-time, variation luffing is not gradually reduced x and z directions, and variation luffing does not increase first in y directions, rear to reduce.Three directions it is constant
The variation tendency with pretightning force is spent, with the increase puted forth effort, the not variation of x and z directions gradually increases, and the not variation in y directions is first
Increase after reduction.It is 500N to roll wheel pretightning force, and hub rotation speed is 20r/min, and car is 8 by forwarding dynamic number.The present invention gives
It is 8 to have gone out when rolling vehicle wheel rotation number, and it is 6000N to roll wheel pretightning force, and rotating speed is 300r/min, in the y directions of nave boss
The analysis in the y directions of wheel is rolled when applying 5000N dead load.In practice, under heavy load, the axial direction of wheel is rolled not
Variation and non-variation fluctuating range are not carried mainly with rolling vehicle wheel rotation number, rolling wheel pretightning force, radial direction for variation, radial direction
The factors such as lotus, hub rotation speed are relevant.Under dynamic loading, the not variation change for rolling wheel is mainly relevant with dynamic loading, with dynamic load
The change frequency of lotus is identical.The change of not variation can also be influenceed by rolling the change of vehicle wheel rotation locus.Speed change rolling truck
Vibration of the wheel-coupled system under heavy load is mainly due to variation does not fluctuate what is caused caused by rotation space change in location.
When speed change roll wheel-coupled system in rotary course by the dynamic force of radial direction when, due to roll inside wheel coupling
Effect, in axial direction, Impact direction and vertically the radial direction with Impact direction can all produce analyze data.Wherein axial direction and stress
The vibration in direction is similar to the changing rule of external force, rolls the constant degree increase of wheel, becomes without variation fluctuating range in decline
Gesture；As pretightning force increases, it is in non-linear increase to roll the constant degree of wheel, and variation luffing does not decline relatively；With radially
Load increase, rolls the radial direction not uneven change of variation of wheel, variation luffing is not in rising trend relatively；With rotating speed
Lifting, roll wheel it is constant degree decline, and relatively not the change of variation luffing without evident regularity.
For quantitative analysis express delivery car time-varying rigidity, using the coupled system of a back-to-back installation of angular contact ball, with this
Based on emulate and study heavy load, the changing rule of the lower express delivery car rigidity of uneven excitation load effect.Major parameter is as worked as
When only by heavy load, the mechanical periodicity of locus is the principal element for producing rigidity fluctuation, is the maximum occurred in rotating
Rigidity value.Define influence of the relative rigidity luffing roadbed pressure to express delivery car time-varying rigidity.The y directions of nave boss apply 500N's
Heavy load, rotor speed is 20r/min.When giving pretightning force for 800N, tri- direction relative rigidity luffings of wheel x, y, z
With the situation of change of roadbed pressure, it can be seen that three direction relative rigidity luffings keep stable after declining rapidly.Give
The rigidity in three directions with roadbed pressure situation of change, it can be seen that rigidity increases with the increase of roadbed pressure.Pretightning force
Influence to express delivery car time-varying rigidity.The y directions of nave boss apply 500N heavy loads, and rotating speed is 20r/min, and car is by holding roadbed pressure
Power is 8.As can be seen that when pretightning force gradually increases, x and z directions rigidity luffing is gradually reduced, y directional stiffness luffings first increase
Greatly, it is rear to reduce, it can be seen that with the increase of pretightning force, the rigidity of x and z directions gradually increases, and the rigidity in y directions
First reduce and increase afterwards.Influence of the radial load to express delivery car time-varying rigidity, pretightning force is 500N, and rotor speed is 20r/min,
Car is 8 by holding roadbed pressure.When heavy load in the y directions of nave boss gradually increases, the change of three directional stiffness luffings of left end
Situation.As can be seen that when radial load gradually increases, x and z directions relative rigidity luffing gradually increases, y directions relative rigidity
Luffing first increases, after have and reduce to a certain degree.The rigidity of x and z directions declines with the increase of radial load in non-linear, and y side
To rigidity first reduce and increase afterwards.Influence of the rotating speed to express delivery car time-varying rigidity.Nave boss y directions apply 500N heavy duty
Lotus, roadbed pressure is 8.
Beneficial effects of the present invention：A kind of distance express delivery car unsteadiness of wheels data system is worked out to wish fast in rural area
Pass that car working environment is changeable, operation type it is various in the case of, can remotely reflect road conditions, different express deliveries can be sent to meet
Car is with the demand to different road conditions.Therefore, the present invention has very big value.
