Description
Technical field
The present invention relates to steering wheel detection technique fields, more specifically, providing a kind of based on promotion steering wheel for vehicle argument
Level detection method.
Background technique
As vehicle increasingly continues to develop, people also increase accordingly the requirement that steering wheel for vehicle manipulates, automobile linear rows
If steering wheel deflection or the not positive problem of steering wheel occur during sailing, vehicle, which is easy sideslip, leads to the generation of safety accident.Side
Just not related with steering wheel argument size to disk deflection or steering wheel, steering wheel argument refers to when vehicle keeps the feelings of straight-going state
Under condition, the angle of steering wheel hub axis and vehicle center axis.It is horizontal to promote steering wheel for vehicle argument, is able to ascend driver
Assurance to the driving condition of vehicle.Current detection method only passes through four-wheel aligner station installation level meter, confirms level meter
Whether reading measures prenex and flare according to laser vapour in acceptability limit, and relevant parameter is adjusted to qualification
In range.Since the method is only limited to four-wheel aligner adjustment, adjusts operating condition and daily road traveling is variant, then also need road
Examination testing staff carries out exhaustive test confirmation to four-wheel aligner adjustment vehicle is completed in runway.But road test testing staff is in other side
It is only operated by visual observation when being detected to disk argument, the steering wheel situation bad with the presence or absence of argument is checked by personal experience,
It is affected by factor and individual subjective factor, and different road test testing staff are also different for the experience of detection direction disk argument, examine
Ability is lack of consistency, and is easy to happen the risk of bad vehicle outflow.
Summary of the invention
It is horizontal based on steering wheel for vehicle argument is promoted that it is an object of the invention to overcome the deficiencies of the prior art and provide one kind
Detection method can quantify check criteria, reduce because of factor and individual subjective factor when runway tests vehicle by introducing measuring device
Caused missed detection risk and bad vehicle flow go out risk.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
It provides a kind of based on promotion steering wheel for vehicle argument level detection method, comprising the following steps:
S1. vehicle to be detected is opened to the starting point in smooth straight trip section；
S2. the steering wheel level measurement device of zeroing calibration will be completed on inspection platform loaded on steering wheel；
S3. driver actuation is travelled vehicle to smooth straight trip road segment end with linear state, and observes the direction
The measurement numerical value of disk level measurement device detects completion if measurement numerical value is within 0 ± 2 °, no to then follow the steps S4；
S4. driver is again travelled vehicle to terminal, if steering wheel is horizontal from the starting point in smooth straight trip section with linear state
The measurement numerical value of measuring device then detects completion within 0 ± 2 °, no to then follow the steps S5；
S5. analytic technique person transfers four-wheel aligner data and carries out analysis and carry out prenex adjustment to vehicle, and toe-in adjustment is completed
Afterwards, driver is travelled vehicle to terminal, if steering wheel level measurement device from the starting point in smooth straight trip section with linear state
Measurement numerical value completion is then detected within 0 ± 2 °, it is no to then follow the steps S6；
S6. carry out prenex adjustment again to vehicle, after the completion of toe-in adjustment, driver again with linear state by vehicle from smooth
Keep straight on section starting point traveling to terminal, if steering wheel level measurement device measurement numerical value within 0 ± 2 ° if detect completion,
Otherwise vehicle is subjected to failure analysis and reprocessed, and confirmed and reprocess effect.
It is of the invention a kind of based on promoting steering wheel for vehicle argument level detection method, incoming direction disk level measurement device,
Judge whether steering wheel is qualified by the measurement numerical value of direction of observation disk level measurement device, no longer needs to detect people according to road test
Member's personal experience's judgement, quantifies check criteria, improves measurement precision.
In order to effective detection direction disk whether deflection or not just, the steering wheel level measurement device is steering wheel water
Level.
Whether in the normal range in order to more accurately detection direction disk argument size, the smooth straight trip section
Distance is 20 ~ 30 meters.
The testing result of each vehicle is checked for convenience, in step s 4, if measurement numerical value has detected within 0 ± 2 °
After by read-record in achievement card.
For the ease of comparing the difference of prenex adjustment front and back data, in step S5 and S6, prenex adjustment is carried out to vehicle
Afterwards, four-wheel aligner data after record is resetted.
Compared with prior art, the beneficial effects of the present invention are:
It is of the invention a kind of based on steering wheel for vehicle argument level detection method is promoted, it introduces and surveys when carrying out runway test to vehicle
Equipment is measured, by steering wheel level measurement device loaded on steering wheel, passes through the measurement numerical value of direction of observation disk level measurement device
Come to steering wheel, whether deflection is detected.Check criteria can be quantified by introducing measuring device, be reduced because factor and individual subjective factor is led
The missed detection risk of cause and bad vehicle flow go out risk.
Detailed description of the invention
Fig. 1 is that the present invention is a kind of based on the flow chart for promoting steering wheel for vehicle argument level detection method.
