Description
Technical field
The present invention relates to technical field of automobile detection, more specifically, it, which is related to a kind of truck combination that is used for, brakes sequential
Detection device and method.
Background technology
Flexibility and high efficiency due to Drop and pull transport, truck combination ratio shared in highway transport vehicle increase year by year
Height has been increasingly becoming the main body of highway transport vehicle.While improving conevying efficiency and saving transportation cost, truck combination
Vehicle performance be also concerned including driving safety.Compared with bicycle, the braking system of semi-trailer train is by tractor
With the organic assembling of semitrailer braking system, the two not only independently of one another but also influenced each other.Only guaranteed tractor and each axis system of trailer
Dynamic phase sequence coordinate is just avoided that the generation of the major accident caused by semi-trailer train braking is unreasonable.Improve semi-mounted vapour
The insensitivity problem of car team vehicle has become the trend of the times of highway transportation development, therefore it is each to study semi-trailer train
The problem of axis brakes sequential, and the control strategy that design support vehicles are stablized is current in the urgent need to address.China is to automobile at present
There is no specific standards for train, tractor and trailer braking protection valve sequential, to realize the matching on tractor and trailer design, go back
There is stretch to walk.Therefore, we are badly in need of a kind of detection method to truck combination braking sequential, to ensure to brake sequential association
It adjusts, ensures insensitivity.
Counter-force drum braking power testing stand and tablet test braking force platform are the common automobile braking detection of domestic contrast
Equipment.Wherein platform brake tester is mainly used for kart brake force dynamic detection, and counter-force Roller brake tester master
It is used for the carrying operated, freight truck braking performance test.The testing stand has simple in structure, performance is stable, speed of experiment is fast etc.
Advantage.But counter-force Roller brake tester can only be detected the coaxial two-wheeled brake force of truck combination tractor, it is impossible to
The brake force of trailer is detected, thus the braking sequential of tractor and trailer can not be detected.
Jiangsu Polytechnical College has manufactured experimently vehicle braking sequential instrument to study truck combination braking sequential.The equipment utilization is infrared
Photoelectric sensor carries out transmission scan to the CD for being carved with 36 scalloped recess (aperture of scalloped recess is 10 degree on CD).
Ready CD is mounted on axle, in order to avoid the interference of outer bound pair sensor, places a sensor at closed gold
Belong in box, the can equipped with sensor is fixed on using elastic cable on vehicle frame, this installation can make can with respect to vehicle body
There is the displacement moved up and down.When CD as axle rotates together, each rotation sensor will export 36 pulse signals.
After vehicle takes braking, axle driven CD does retarded motion, and at this moment the period of output of pulse signal is progressively longer, Zhi Daoche
Take turns the output of locking no signal.For pulse signal after amplifying shaping, mating photoelectricity oscillograph is the arteries and veins that can obtain each wheel output
Signal graph is rushed, so as to obtain braking sequential, advantage is precision height, dependable performance, and shortcoming is that cost is expensive, for semi-trailer train
Experiment is difficult.
Invention content
The purpose of the present invention is researching and developing a kind of detection device and method for truck combination braking sequential, to realize to vapour
