Background technology
Automobile brake is with the travel kinetic energy of automobile on road, changes heat exhaustion into through the friction of brake inside and falls, and the kinetic energy that travels has exhausted, and automobile has also just stopped.
At present, the domestic anti-force type that generally uses is automobile brake test bed, checks the braking ability of vehicle in use in the mode of measuring damping force.Be subjected to the restriction of principle, structure, the drum rotation speed of anti-force type brake platform is very slow, is equivalent to about speed of a motor vehicle 3km/h, and its braking procedure and the automobile damped condition on road differs greatly.Present most of automobile all has abs braking (anti-lock) function, the minimum speed of a motor vehicle that the ABS system works must be more than 10km/h, this means that the anti-force type brake platform can't check the automobile of abs braking, its existence is as ornaments because can not find alternate device.Change an angle, all have the vehicle in use of abs braking, and its braking ability can't be judged, exists great potential safety hazard.
The drum rotation speed of inertia-type brake test bench can be near 100km/h, and braking procedure and automobile brake very approachingly on road, can check the automobile of abs braking.Its inspection principle is: automobile is parked on the check stand, the wheel of direct motor drive cylinder driving automobile, and the road surface that the cylinder of rotation is equivalent to move is used for the transport condition of simulated automotive on road.During automobile brake, what detent consumed is the rotation function of cylinder.Under the identical condition of the speed of a motor vehicle, if the rotation function of cylinder equates with the kinetic energy that travels of automobile on road that just in time the assay of stand braking then is consistent with braking effect on the road.

The Interventions Requested of check-out console have:
Brake hard, some braking, parking braking, slide and speedometer, chassis measurement of power, transmission resistance and claim wheel load, heavy, the car weight of axle automatically.
The concrete course of work of check-out console is as follows: (verifying as example with the front-wheel brake hard)
At ordinary times, lifting mechanism is the most significant digit state, and the frame beam 26 of weighing is contour with cylinder, and auxiliary cylinder 2 is braked the hoof plate and embraces, and three collet type clutch couplinges 12 are all in released state, and the 3rd cylinder 19 exceeds the about 25mm of frame beam that weighs.
For vehicle front presses when weighing frame beam 26, the 3rd cylinder 19 has been depressed, touches location switch and sends the signal that puts in place, makes computer when prompting is stopped, and control is to two front-wheels weigh automatically (two wheel load sums are heavy for axle).After weighing, display transfers key frame automatically to, and can login automobile license number, wheelbase, these data of wheel diameter and select required Interventions Requested and front and rear wheel this moment.
Behind login and the option, promptly enter the program and the picture of this project, can begin check.
Earlier by the decline key, claw-type clutch 12 combinations on the lifting shaft 23, by line shaft 11 and sprocket wheel chain 6 driven rotary, drive 4 screw jack 21 run-in synchronisms through reduction gearing 22, front-wheel on weigh frame beam 26 and the beam is descended, brake arm 32 also sagging a little, brake-shoe plate and auxiliary cylinder 2 are disengaged.When front-wheel drops to when being lower than the about 15mm in front-wheel bottom by the idler and the frame beam 26 of weighing, another limit switch on the 3rd cylinder 19 is touched, and cuts off the decline circuit automatically and makes the frame beam 26 of weighing stop decline.Unclamp the decline key.
Teleswitch is clipped in above the automobile brake pedal, press the ON key, two claw-type clutch 12 combinations on the line shaft 11, inverter control motor 7 is slowly started, the 3rd cylinder 19 under head roll, wheel, current vortex machine 3 and flywheel 4, the front-wheel quickens gradually, and display shows the speed of a motor vehicle always.Just keep this frequency when frequency converter output reaches 50HZ, the speed of a motor vehicle of this moment stabilizes to 55km/h.
Press the OFF key, frequency converter and motor 7 outages, cylinder, flywheel run out of steam but very big inertia are arranged, freely slow down with wheel, when being decelerated to 50km/h, the display prompting that sends out a warning, operating personnel's enforcement brake hard of rapidly automobile brake pedal one pin being floored.
Just stepped on moment at brake pedal, the teleswitch that is clipped in above the pedal moves, and controls two claw-type clutch 12 on the one hand and separates immediately, and rapidly variable power supply is connected the field coil of current vortex machine 3; Produce brake signal on the other hand and give capture card and computer.Whole braking procedure about 1 second, it is test ending that the speed of a motor vehicle reduces to zero by 50km/h, display transfers key frame automatically to, can enter the brake inspection result screen by key frame, can see following content: the braking deceleration curve map of braking distance, braking rolling distance, drawing brakes distance, braking deceleration, brake coordination time, braking duration, wheel load, axle weight, car weight and each wheel.
If check does not have the automobile of abs braking in early days, braking distance among the brake inspection result (the accumulative total girth that cylinder rotates) can be obviously greater than braking rolling distance (the accumulative total girth that the 3rd cylinder rotates), this is because wheel has stopped because of the detent locking, the 3rd cylinder inertia is minimum also stops simultaneously, and the also remaining very big inertia of cylinder and flywheel, be enough to overcome and be rotated further with the friction of tire, after a while along with inertia reduces just can stop, thereby form tangible drawing brakes distance (drawing brakes distance=braking distance-braking rolling distance).
And the automobile of abs braking is arranged now, kinetic energy is braked device consumption entirely, wheel can locking during braking, kinetic energy consumption is over, wheel has also stopped, the accumulative total girth that cylinder and the 3rd cylinder rotate differs very little, that is braking distance equates substantially that with the braking rolling distance drawing brakes distance is then near zero.
Front-wheel brake hard test ending can be by lifting key, and the frame beam 26 of weighing rises to most significant digit and can touch limit switch and stop automatically, and the brake arm of pull-up simultaneously 32 makes the brake-shoe plate embrace auxiliary cylinder 2, is convenient to front-wheel and sails out of stand.The process and the front-wheel of trailing wheel brake hard check are identical.Process and unique difference of brake hard of some brake inspection are: operating personnel put and step on that brake pedal unclamps immediately, allow the speed of a motor vehicle have and obviously reduce to get final product.
