Detailed description of the invention
The automotive suspension vertical deviation measurement apparatus embodiment provided the present invention below in conjunction with the accompanying drawings is carried out in detail
Thin description.
With reference to shown in Fig. 1, a kind of automotive suspension vertical deviation measurement apparatus that the present invention provides, including position
Displacement sensor 1, fixing axle 2, bearing 3, fixed disk 4, guide post 6 and guide post sucker 7, institute's rheme
Displacement sensor 1 is connected with one end of fixing axle 2, the other end of fixing axle 2 and bearing 3 interference fit,
Described bearing 3 is fixed in the centre bore of fixed disk 4, and described fixed disk 4 is fixed by special bolt 5
In the via in the middle of rim for automobile wheel;The lower end of described guide post 6 is arranged on the installation above fixing axle 2
Hole 22 is interior, upper end is arranged in the positioning through hole 74 on guide post sucker 7, described guide post sucker 7
Absorption is being positioned on the vehicle body above fixing axle 2, and guide post sucker 7 offers for fixing sensing
Device bracing wire or the fixing groove 75 of pull bar.
In measurement, guide post sucker 7 is made to be adsorbed in the bodywork surface directly over wheel center, guide post 6
Upper end through the positioning through hole 74 of guide post sucker 7 and can be dynamically connected with it, fixing axle 2 is inserted in lower end
On installing hole 22 and be secured to connect, fixed disk 4 is with tire synchronous axial system, guide post sucker 7 phase
Position for vehicle body remains constant, guide post 6 with vehicle body pitch and along guide post sucker 7
On positioning through hole 74 move up and down, stop fixing axle 2 to rotate with fixed disk 4 under frictional force effect,
Thus the rotation of limiting displacement sensor 1, it is ensured that displacement transducer 1 and guide post sucker 7 and thereon
The relative position of fixing groove 75, when fixing groove 75 is fixed in the bracing wire of displacement transducer 1 or one end of guide rod
Time interior, bracing wire or guide rod are perpendicular to guide post sucker 7 all the time, and the horizontal level of guide post sucker 7 is
The horizontal level of automotive suspension, i.e. bracing wire or pull bar are perpendicular to automotive suspension all the time, the automotive suspension recorded
Vertical deviation near its actual value;Prior art is taked directly that one end of displacement transducer 1 is solid
It is fixed on the mode of amortisseur due to vehicle body, the other end and carries out the measurement of automotive suspension vertical deviation, due to
There is certain angle in mounting means and automotive suspension, measured shift value is bigger with actual value deviation
Or inaccurate, to compare with prior art, the automotive suspension vertical deviation measurement apparatus that the present invention provides is being surveyed
During amount, the bracing wire of displacement transducer 1 or pull bar are perpendicular to pendant surfaces under the effect of guide post 6 all the time,
Bracing wire or pull bar constantly elongate with the upper and lower displacement drop in automobilism or shrink, and constantly make sensor electricity
Resistive thus realize change in voltage, thus measure the vertical deviation of automotive suspension, and the vertical position recorded
Move the close actual value of maximum possible.
Shown in seeing figures.1.and.2, described fixing axle 2 offers the level indicator for placing level indicator
Groove 21, the installing hole 22 for fixed guide pole 6 and the center of level indicator groove 21 on fixing axle 2 connect
Line and the centerline axis parallel of fixing axle 2, before measuring, install described automotive suspension vertical deviation and survey
After amount device, level indicator is positioned in level indicator groove 21, adjusts after whole device is in level,
Take out level indicator, make automobilism measure.
With reference to shown in Fig. 1 and Fig. 3, owing to the median plane of tire and the bodywork surface directly over it are laterally
On there is a certain distance, it is the poorest to exist, and i.e. the two is not in same perpendicular, and different automobile types
The horizontal poor difference of automobile, in order to leveling wheel median plane with its directly over bodywork surface the poorest,
The resilient transition apparatus 61 of tool it is provided with near the position of lower end, it is preferred that described mistake at guide post 6
Cross the centre of device 61 to have and be perpendicular to guide post 6 and there is the groove of certain depth, for different wheels
Tire median plane with its directly over bodywork surface the poorest, the non-transition apparatus part of described guide post 6
Remain perpendicular to the direction of fixing axle 2, described transition apparatus 61 and the non-transition apparatus part of guide post 6
Be not arranged on the same straight line be, i.e. the overall of transition apparatus 61 produces or produces doubling bending along groove,
Receive tire centerline face with its directly over bodywork surface the poorest, make the upper end of guide post 6 protect all the time
Hold in the positioning through hole 74 vertically penetrating guide post sucker 7, lower end vertical with described fixing axle 2 all the time,
Being easy in the automobile of different automobile types, described fixing axle 2 becomes relative to the lateral separation of bodywork surface
During change, additionally it is possible to keep itself and institute's displacement sensors 1 to be in level, improve and measure numerical value
Accuracy.
