Description
Technical field
The utility model relates to a kind of automobile parking braking and pulls force tester.
Background technology
It is a kind of equipment of directly testing various self-propelled vehicle Parking Brake value of thrusts that automobile parking braking pulls force tester, the present domestic directly equipment of test machine motor-car Parking Brake value of thrust that also do not have.When test machine motor-car braking during standstill pulls drg on the drum reaction type brake test bench, pull braking arbitrarily with drawing car person oneself entirely at present, can not quantize its firmly size.
Summary of the invention
The purpose of this utility model provides a kind of automobile parking braking and pulls force tester, and it can directly test and show various self-propelled vehicle Parking Brake value of thrusts, to demarcate the correlated performance parameter of automobile.
For achieving the above object, the utility model is taked following design plan: this automobile parking braking pulls force tester and is made up of force-measuring sensing device and display instrument, described force-measuring sensing device comprises: direction handle unit, and it connects a twisted seat by oscillating bearing; One inserts and puts the valve seat of force transducer, and its seat of honour is connected with free bearing one end, and the other end is connected with the belt collar by screw, and the output line of force transducer is connected with the signal input part of display instrument.
The utility model has the advantages that: compact integral structure, stable performance, easy to operate, accurate measurement, long service life; Make things convenient for the staff that the firmly size of various self-propelled vehicle Parking Brakes is measured, demarcated; And applied widely, use direct supply, be convenient to the user and use at detection line cooperation brake testing stand or in varying environments such as car detections in real time.

The specific embodiment
The utility model automobile parking braking pulls force tester and is made up of force-measuring sensing device and display instrument.
As Fig. 1, Fig. 2, shown in Figure 3, described force-measuring sensing device comprises: direction handle unit 1, and it connects a twisted seat 3 by oscillating bearing 2; One inserts and puts the valve seat of force-measuring sensing device, and its seat of honour 4 is connected with free bearing one end, and following seat 7 is connected with the belt collar 8 by screw, and the output line 5 of force transducer 6 is connected to the signal input part of display instrument.
Force transducer is that pulling force is converted to the converting electrical signal device, is actually according to intelligent this electrical bridge principle.Elastic body produces elastic deformation under external force, make the sticking resistance strain gage of metal surface that stands in also in company with producing distortion, after the resistance strain gage distortion, its resistance will change (increase or reduce), through corresponding metering circuit this resistance variations is converted to electric signal (voltage) output again, with external force size transaction value direct ratio, thereby finish the process that external force is transformed to electric signal.
Display instrument adopts direct supply, and as shown in Figure 4, output voltage stabilization is at 5v.
The electrical schematic diagram of display instrument is referring to Fig. 5.
Its principle of work is as follows:
To pull force tester belt sleeve ring set on the hand lever handle, upwards spur hand lever with hand direction of passage handle, be pulled to conventional fixed position (3-4 tooth), the force-measuring sensing device is delivered to display instrument (can select hand-held liquid crystal display instrument for use) with signal, demonstrates hand braking value of thrust (N).Force transducer is after being subjected to pulling force, and the bridge type resistance strain gage that metallic object and metal body surface are pasted produces elastic deformation, and resistance strain gage just produces a voltage signal.Signal is delivered to high precision operating amplifier ADOP-07 amplify, this amplifier has extremely low offset voltage (10uV) and bias current (0.7nA), extremely low temperature factor, and long-time stability are good.Signal after will amplifying is again sent into A and D converter MC14433 and is carried out analogue to digital conversion, its resolution of biproduct somatotype MC-14433 is three and half, quite 1 of binary one is strong, be output as binary-coded decimal through the multichannel modulation, operating voltage range ± 5V,-5V voltage is to provide through voltage transformation Voltage stabilizing module ICL7660, and its reference voltage also is to be provided by reference voltage circuit module TL7705, and outward element is few.MC-14433 is the analog voltage amount of sending into a digital signal by Integral Transformation, finish the arrangement of data and the control and treatment of data by 8-bit microcontroller AT89C51 again, treated data will be divided into two-way and send, one the road delivers to 8 addressable latches 4099 from the P2 mouth of 8-bit microcontroller AT89C51 goes here and there-and digit conversion, show by LCD display; Another route serial sends a mouthful TXD and sends, and finishes level conversion through phase inverter 74HC04 and aerotron 9015, delivers to the RS-232 mouth again so that online use.During opening initialization, 8-bit microcontroller AT89C51 detects the demarcation key and whether presses (pressing next position key and hundred keys before the start simultaneously), then enters the demarcation state if having, otherwise enters test mode; At test period, if there is reset key to press, program is then removed initial value; If there is hold key to press, the maxim of this measurement will be kept.Integrated package 93CS46 is EPROM serial input and output memory devices.
This tester instrument adopts plastic casing, and anti-electromagnetic interference is strong.Compact integral structure, the data of collection are handled with micro controller system, have the advantage of stable performance, easy to operate, accurate measurement, long service life.Use direct supply, be convenient to that the user cooperates brake testing stand on detection line or with using in the varying environments such as the real-time detection of car.This tester can be measured various self-propelled vehicle braking during standstill hand value of thrust sizes, and shows (follow the tracks of and show and the peak value maintenance) with LCD display.
The utility model is used in and draws that car person pulls that glancing impact measures size firmly or the firmly size when detecting the driver in good time and pull Parking Brake with car.
