Describe the present invention below with reference to the accompanying drawings in detail, it is more obvious that purpose of the present invention and effect will become.
As shown in the figure, the invention provides a kind of motor-driven plate type braking force measuring apparatus of automobile, it is mainly by front shroud 1, checkered plate 2, driving chain fixed support 3, checkered plate guide bearing 5, driven sprocket transmission shaft 6, driving chain 7, chain sprocket drive axle bearing and bearing seat 8, drive sprocket transmission shaft 9, drive sprocket 10, channel steel shape guide rail 11, back shroud 12, motor 13, wheel box 14, force cell 15, dynamometer link 16, first joint flange 17, second joint flange 18, force-detecting position support 22, unit head base plate 23, driven sprocket 24, first limit switch 25, second limit switch 26 and checkered plate loading bearing 27 are formed.The present invention is installed in the pit of ground, and guarantees that checkered plate 2 is parallel with the level ground.
As shown in Figure 5, checkered plate 2 bottoms are welded with driving chain fixed support 3 and triangle reinforcement 4, and driving chain fixed support 3 is connected with driving chain 7, and triangle reinforcement 4 makes that driving chain fixed support 3 is more firm.
As shown in Figure 6, the drive sprocket 10 installed of the driven sprocket 24 installed with driven sprocket transmission shaft 6 middle parts respectively of driving chain 7 and drive sprocket transmission shaft 9 middle parts matches.Driven sprocket transmission shaft 6 and drive sprocket transmission shaft 9 are installed on chain sprocket drive axle bearing and the bearing seat 8, chain sprocket drive axle bearing and bearing seat 8 by bolt on the frame (not shown).Channel-section steel type guide rail 11 also is fixedly mounted on the frame (not shown).
Shown in Figure 4 and 5, checkered plate 2 both sides are equipped with several checkered plate guide bearings 5 and checkered plate loading bearing 27 at interval, checkered plate guide bearing 5, checkered plate loading bearing 27 match with both sides channel-section steel guide rail 11, guarantee that checkered plate 2 only has a freedom of motion of horizontal direction.
As shown in figs. 1 and 4, in front shroud 1 and back shroud 12 bottoms, checkered plate 2 moves horizontally in the bottom of front shroud 1 with back shroud 12 channel steel shape guide rail 11 by bolt.
As shown in Figure 3, motor 13 comprises motor output shaft 19, wheel box 14 comprises wheel box input shaft 20 and output shaft of gear-box 21, and motor 13 is fixed on the unit head base plate 23 by coupling bolt and nut with wheel box 14, and dynamometer link 16 is fixed on the unit head base plate 23.Motor output shaft 19 is connected with wheel box input shaft 20 by first joint flange 17, to transmit moment of torsion; Output shaft of gear-box 21 is connected with drive sprocket transmission shaft 9 by second joint flange 18, to transmit moment of torsion.A force-detecting position support 22 is installed by coupling bolt in force-detecting position position, force cell 15 top, and the bottom surface of the upper surface of force-detecting position support 22 and dynamometer link 16 cooperatively interacts, and force cell 15 is fixed on the frame (not shown) by coupling bolt.
As shown in Figure 2, first limit switch 25 and second limit switch 26 are fixed on both sides, channel-section steel guide rail 11 front and back.
Before work of the present invention begins, at first the required measurement wheel of vehicle is driven on the checkered plate 2, car body is fixed.Compare with roller brake tester, the measured result of flat mode more approaches the road driving situation of actual vehicle.
During the work beginning, motor 13 energisings, motor output shaft 19 rotates thereupon, by first joint flange 17 moment of torsion is passed to wheel box input shaft 20, wheel box 14 passes to drive sprocket transmission shaft 9 with the moment of torsion of transmission by the output shaft of gear-box 21 and second joint flange 18, it is stressed to drive drive sprocket 10, this moment is owing to driving chain 7 is stressed, drive checkered plate 2 horizontal direction forces, checkered plate 2 produces and moves horizontally, this moment, force-detecting position support 22 tops on the force cell 15 contacted with dynamometer link 16 bottoms, and force cell 15 records data, and the data of the power that force cell 15 is measured pass to PC by data line.These data are through just obtaining the damping force of measured motor vehicle after converting.
The principle of measuring damping force is the relation that opplied moment equates with the moment of reaction, that is: force-detecting position support 22 tops and the pulling force of the distance of dynamometer link 16 bottom contact points and sensor 15 power that is subjected to the long-pending radius of action that equal drive sprocket 10 and chain of output shaft 21 centers of wheel box 14 to the sensor 15 is long-pending, this is a pair of trimming moment, the stressed pulling force that has also just obtained chain by induction pick-up 15, the i.e. damping force that produces by wheel braking on the checkered plate 2 like this.
Because this device drive disk assembly is less, so reliable operation.After measuring end, checkered plate 2 can be by the reverse operation of motor 13, and when checkered plate 2 was withdrawn into second limit switch 26, PC was controlled motor movement, and at this moment checkered plate 2 just turns back to reference position, so that measure next time.
The effect of first limit switch 25 is: when normal condition is measured braking, checkered plate 2 can not move to the position of first limit switch 25, in order to prevent accident, in case checkered plate 2 moves to the position of first limit switch 25, PC is controlled motor counter-rotating immediately and checkered plate 2 is withdrawn into reference position is carried out manual intervention.
In addition, this device is suitable for the detection of motor vehicle braking abilities such as all kinds of wheeled (comprising two-wheeled, three-wheel, four-wheel), crawler type.Measure four-wheeled vehicle and can use two these devices of cover to be symmetrically arranged, measure the damping force of left and right sides wheel or crawler belt respectively.
