Electronic switch is infrared type electronic switch or laser type electronic switch.
Transmitting terminal is fixed on erecting frame, and erecting frame is placed in roadside.
Electronic switch has two pairs at least, along automobile direct of travel, arranges.
Active braking distance is the center line of the center line of transmitting terminal receiving end when projecting to automobile on road surface and the stopping distance between the projection of road surface.Said center line, refers to the center line between head and the tail two transmitting terminals/receiving end herein.
Erecting frame is the lift erecting frame of capable of regulating transmitting terminal height.
The setting height(from bottom) of transmitting terminal and receiving end is identical.
Principle of the present utility model is: transmitting terminal is arranged on roadside, receiving end is arranged on automobile side, when automobile with certain speed (normally 30km/h or 50km/h) through out-of-date, transmitting terminal and receiving end docking, receiving end triggers the effect of trigger switch device, trigger switch device triggers portable vehicle brake performance tester and enters measuring state, and automobile starts braking simultaneously.When automobile stops completely, measure the distance between transmitting terminal and receiving end, be the active braking distance of automobile.The braking distance indicating value of active braking distance and portable vehicle brake performance tester is compared, can check the accuracy of this indicating value.
Generally speaking, the utlity model has following advantage:
1. only adopt electronic switch and trigger switch device, can record active braking distance, apparatus structure is simple, and operation is convenient.
2. adopt Liftable type erecting frame, after receiving end has been installed, according to the height of transmitting terminal on the height control erecting frame of receiving end, easy for installation.
3. adopt two pairs of above electronic switches that arrange along automobile direct of travel, need every pair of electronic switch to dock just can to excite to trigger the device action that opens the light simultaneously, Accurate Calibration starts the position of braking, guarantees to have measurement result accurately.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model, and wherein, below solid line is partly automobile in starting application position, and dotted portion is that automobile is in complete stop position.
Fig. 2 is circuit diagram of the present utility model.
Wherein, 1 is transmitting terminal, and 2 is roadside, and 3 is receiving end, and 4 is automobile, and 5 is trigger switch device, and 6 is portable vehicle brake performance tester, and 7 is distance-measuring device, and 8 is active braking distance, and 9 is positive source, and 10 is power cathode.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
A braking distance calibrating installation for portable vehicle brake performance tester, comprising: electronic switch and trigger switch device.
Electronic switch comprises transmitting terminal and receiving end, and transmitting terminal is fixed on erecting frame, and erecting frame is placed in roadside, and receiving end is fixed on automobile side.The position of adjusting erecting frame, makes transmitting terminal and receiving end be positioned at sustained height.Electronic switch has two groups, along automobile direct of travel, arranges, and when every group of transmitting terminal and receiving end dock respectively, just excites trigger switch device action.Electronic switch can be selected infrared type electronic switch or laser type electronic switch.
Trigger switch device is existing device, receives after the signal that receiving end sends, and to the triggering port of portable vehicle brake performance tester, sends trigger pip, and portable vehicle brake performance tester receives after this trigger pip, automatically controls automobile brake.
The triggering port of receiving end, trigger switch device and portable vehicle brake performance tester joins successively.
During test, automobile with certain speed travel by, when transmitting terminal and receiving end correlation, receiving end excites the effect of trigger switch device, and then triggers portable vehicle brake performance tester and start to enter measuring state, automobile starts braking simultaneously.Automobile is implemented braking to stopping completely and keeping motionless, reads the braking distance indicating value of portable vehicle brake performance tester.Now, adopt center line that distance-measuring device measures transmitting terminal at the center line of road surface projection (beginning braking point) and receiving end the distance between road surface projection (stop), be active braking distance.Can obtain active braking distance thus, and by comparing with braking distance indicating value, calibrate this indicating value.
