Description
Technical field
Automotive accessory technical field is the utility model is related to, more particularly, to a kind of unmanned vehicle wheel automatic straightening system
System.
Background technology
With the continuous development of automobile industry, the performance more and more higher of automobile, but in order that each parts energy of automobile
Enough possess longer service life, human pilot needs to be driven in strict accordance with regular flow and shut-down operation.However, people
It is particularly easy to ignore these crucial details operations again during regular job, such as parking rear wheel does not return just.If car
Hui Zhenghui does not make steering load excessive to wheel, and suspension is caused to damage, and can also hurt wheel what is more.
If wheel, which does not return the parts such as the associated gear that can just make steering wheel, is present in a stress, can so lead
Cause steering linkage can not normally return to original position, will result in these part accelerated ageings or deformation in the course of time.Once
Wheel is not returned just, and wheel can be made an inclined angle occur because suspension is connected to wheel, this state for
The suspension of automobile is that have certain negative effect.Damping i.e. in suspension be lined with a stress by its can not return,
Excessive, the internal components aging of suspension load will be so caused for a long time, can also cause the vicious circle of chain reaction.It is false
As wheel does not return just, tire shoulder and a part of tyre surface stress can be caused.Therefore the side wall of wheel can produce very big pressure, cause car
Force unbalance is taken turns, so can not only greatly increase the impaired and aging of wheel side wall, the peace such as also results in tire gas leakage, blow out
Full hidden danger occurs.
As can be seen here, a kind of unmanned vehicle wheel automatic straightening system how is worked out, possesses simple in construction, automaticity
High, the advantages of aligning accuracy is good, be current those skilled in the art's urgent problem to be solved.
The content of the invention
In order to solve the above problems, the utility model provides a kind of unmanned vehicle wheel automatic straightening system.
A kind of unmanned vehicle wheel automatic straightening system of the utility model, including the servomotor in steering spindle, institute
State servomotor to be electrically connected connected control system by wire, the control system electrically connecting position sensor, the position sensor
Installed in the steering linkage for controlling vehicle wheel rotation direction.After parking of automobile, the control system receives auto brake system
The stop sign that system is sent, and the angle of inclination of position sensor detection gained wheel and rotation information described in continuous collecting, institute
The running status instruction that control system issues the servomotor is stated, is provided between the control system and the servomotor
The running status of the servomotor is converted into electric signal and by signal wire by the electric signal by encoder, the encoder
The control system is transferred to, the control system is carried out more by the feedback signal of the encoder to the control system
Accurately regulation and control, the servo motor transmission connect the steering spindle, and the steering spindle is driven and steering spindle vertical connection
Steering wheel rotate, with realize stop after the wheel self-aligning.It can be seen that the setting of the encoder can make described watch
Taking motor being capable of more efficiently completion wheel correction work.
Further, the control system is arm processor.
Further, the control system electrically connects with the voice system in automobile, and the control system is by controlling
Predicate system for electrical teaching makes voice system send correction progress msg.
Further, during wheel returns just, the voice system sends " wheel goes back to center " prompt message；Work as wheel
Hui Zhenghou, the voice system send " wheel is returned and just finished " prompt message.
Further, after wheel is in back positive position, the control system sends to the servomotor and shut down
Order, and stop gathering angle of inclination and the rotation information of the position sensor detection gained wheel.
A kind of unmanned vehicle wheel automatic straightening system of the utility model, compared with prior art with advantages below：
In the unmanned vehicle wheel automatic straightening system, it is with real-time perception automotive steering structure by set location sensor
Steering linkage status, to detect the information such as the angle of inclination of the wheel and direction, and position is gathered by control system
The detection information of sensor is put, is changed into electric signal after control system is processed to information and is passed to control with steering spindle
The running status of the servomotor of dynamic connection, due to the steering spindle and steering wheel vertical connection, so the steering spindle oneself
Dynamic operating carries out the work of nobody automatic correction wheel equivalent to steering wheel.
Started working after control system receives stop sign, control system is just stopped after wheel returns just.Can
See the design achieves after parking, the effect of automobile self-aligning wheel.The design compensate for people parking after often forget about and
Shi Huizheng wheels and cause automotive interior parts service life shorten the defects of.It is again because automatic using whole unmanned vehicle wheel
Correction system carries out information detection using the high sensor of sensitivity, by the strong control system of processing data information ability such as
Arm processor is controlled, and possesses the feedback regulation function of encoder, so the design can reach wheel correction accuracy
Purpose high, restoring time is short.
