Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is expanded on further.
A kind of automobile brake experimental bench lifting device with speed measuring drum, including speed measuring drum mechanism and lifting support machine Structure.The speed measuring drum mechanism includes speed measuring drum 1 and installs the installing component of speed measuring drum;The installing component includes stent 2nd, supporting plate 3;2 one side of stent is also equipped with wheel speed sensors 12.The lifting supporting mechanism includes lifter plate 4, resilient support Part and lift assemblies;The helical spring 11 that the elastic supporting member for supporting optical member is arranged symmetrically in 3 lower section of supporting plate for two;The lifting group Part includes the fluid power cylinder 9 of four corners for being symmetricly set on lifter plate 4, and hydraulic circuit passes through synchronous valve synchronously distribution control System.Lift assemblies can lift lifter plate.The power cylinder 9 of this obvious hydraulic pressure can also be replaced with the structure of air pressure.Resilient support Part can be substituted with structures such as leaf springs.
Lifter plate 4 is arranged in parallel with speed measuring drum 1.As shown in Fig. 2, the centre of lifter plate 4 has through hole 16, through hole 16 Length and width is all higher than the length and width of speed measuring drum 1, and helical spring 11 supports installing component, makes speed measuring drum 1 logical from the through hole 15 Lifter plate 4 is crossed, realizes the lifting of roller.Lifter plate 4 and supporting plate 3 are respectively arranged below with band lantern ring 5, and steel cable 6 passes through band lantern ring 5 It is connected on lifter plate 4 and supporting plate 3, it is exceptionally straight via fixed pulley 7 among steel cable 6.Steel cable 6, band lantern ring 5 and fixed pulley 7 are along survey Fast roller is symmetrical arranged two groups.Two groups can allow stress in 3 lifting process of supporting plate evenly, to avoid crooked.
The lift assemblies, helical spring 11, fixed pulley 7 are fixed on same pedestal 8, can also all be fixed on base station Or on concrete floor.Between supporting plate 3 and pedestal 8, each /V group that one group of limitation speed measuring drum is set to move horizontally in left and right Part:/V steel plate 10 and 10 ', avoiding roller, double swerve causes to test the speed inaccurate when automobile drives into, is driven out to and tests the speed.It is described One group of /V steel plate 10 and 10 ' includes being fixed under the upper fixing steel plate 10 ' and steel plate of 3 upper end of supporting plate along speed measuring drum both sides End is welded on the lower fixing steel plate 10 on pedestal 8, and plate face of the lower fixing steel plate 10 respectively with a upper fixing steel plate 10 ' is pasted It closes.The /V steel plate, may also be arranged between supporting plate 3 and lifter plate 4.
Between lifter plate 4 and pedestal 8, left and right is each to set one group of limit assembly:/V steel plate 10 and 10 ', to lifting branch Support mechanism carries out /V, prevents that double swerve avoids the unbalance stress such as roller, causes when automobile drives into, is driven out to and tests the speed for it Equipment deforms, and causes to test the speed inaccurate.One group of /V steel plate include the upper limit plate 10 ' that steel plate upper end is welded on lifter plate 4 and Steel plate lower end is welded on the lower limiting board 10 on pedestal 8, and the inner plate surface of upper and lower /V steel plate contacts with each other, plate face fitting.
As shown in figure 4,13 be tested wheel, 14 be master rotor, and 15 be auxiliary cylinder.Experiment is driven into/is driven out in automobile preparation During platform, lift assemblies provide upward thrust, are risen so as to which lifter plate 4 be promoted to rise to major and minor roller sustained height, i.e. satisfaction Drop plate 4 can just support wheel, prevent automobile wheel-slip in the process of moving, quickly drive into/be driven out to braking convenient for automobile Experimental bench.Meanwhile the upward thrust that lift assemblies are provided drives steel cable 6, makes supporting plate 3 in the drawing active force of steel wire rope 6 Lower compression spring 11, is gradually reduced, speed measuring drum is avoided to be contacted with wheel.
As shown in figure 5, when being tested the speed by inspection automobile preparation, lift assemblies, which provide downward thrust, declines lifter plate 4, simultaneously Steel cable 6 is driven, supporting plate 3 is gradually increasing under the action of 11 bounce of spring, and speed measuring drum is allowed just to be contacted with wheel, convenient The measurement of automobile wheel speed.During testing the speed, according to actual demand roller can be selected to drive test the speed mode or the wheel of vehicle wheel rotation The mode that tests the speed that roller is driven to rotate.Between the limiting plate up and down of steel plate 10, always in the contact condition fitted closely, prevent Wheel during the test, rock by speed measuring drum mechanism, so as to influence accuracy of detection.
Certainly, air pressure mechanism or other machines that can be provided power and reach same effect can also be used in the lift assemblies Structure.Such as:Air bag is installed below in lifter plate 4, using air pump compresses air, compressed air is filled with air bag, air bag expands against Lifter plate 4, so as to complete to lift.Meanwhile it in order to ensure entire speed measuring drum mechanism and lift the steady lifting of supporting mechanism, lifts It rises component and can be selected more, and be uniformly distributed in the corresponding each stress point position in 4 lower section of lifter plate.
