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
