Abstract
The present invention relates to one kind to be used for vehicle wheel load self-level(l)ing overturn-preventing support device.Vehicle wheel load measuring instrument needs to keep when measuring vehicle wheel load relative to ground level working condition, but there are some experiments such as centroid measurement, it then needs to measure vehicle wheel load on the platform for changing vehicle centroid height or the certain angle that leans forward, therefore just needs a kind of in the auxiliary support apparatus that can still make wheel load measuring instrument keep horizontal operation state on platform that leans forward.Its composition of the invention includes: support base (1), the support base upper end is equipped with rotary axis system (3), rotary axis system connection -- swing arm structure (2) is equipped with vehicle wheel load measuring instrument (4) in the swing arm, and the swing arm side has cylinder spacer pin (5).The present invention is leveled for vehicle wheel load measuring instrument.
Description
Technical field
The present invention relates to one kind to be used for vehicle wheel load self-level(l)ing overturn-preventing support device.
Background technique
It can be commonly applied to vehicle wheel load measuring instrument in vehicle centroid measurement, need to keep phase when measuring vehicle wheel load
For ground level working condition, but there are some experiments to need on the platform for changing vehicle centroid height or the certain angle that leans forward
Measure vehicle wheel load, the measuring instrument internal measurement structure if directly placing wheel load measuring instrument on the platform in the certain angle that leans forward
It will lead to measurement result and have trueness error, so that it is inaccurate to make measurement result, and also do not meet wheel load instrument operating specification, because
This just needs a kind of in the Auxiliary support that can still make vehicle wheel lotus measuring instrument keep horizontal operation state on platform that leans forward
Device.
Summary of the invention
The object of the present invention is to provide one kind to be used for vehicle wheel load self-level(l)ing overturn-preventing support device.
Above-mentioned apparatus function is achieved through the following technical solutions:
One kind being used for vehicle wheel load self-level(l)ing overturn-preventing support device, and composition includes: support base, it is characterized in that: described
Support base upper end is equipped with rotary axis system, and the rotary axis system connects swing arm structure, is equipped with vehicle on the swing arm structure
There are cylinder spacer pin in wheel load measuring instrument, the swing arm structure side.There are arc-shaped limit hole, institute in the support base two sides
Swing arm amplitude of fluctuation can be limited within ± 12 ° by the cylinder spacer pin stated by arc-shaped limit hole.I.e. when experiment porch inclines
When tiltedly within ± 12 °, the swing arm structure can keep the state relative to ground level.The height of the rotary axis system answers height
In the height of center of mass for being measured vehicle, the generation for the phenomenon that prevents from toppling when swinging.The support base and swing arm
It should prevent from colliding in the case of ± 12 ° of inclination there are enough gaps between structure.The support base is provided with strip hole, can
It is accurately adjusted with the vehicle for wheelbases different under different experiments platform.
The utility model has the advantages that
The present invention can keep vehicle opposite ground holding on wheel load measuring instrument horizontal in a certain range, guarantee wanting for measurement
Summation precision.And with tradition self-regulated leveling device compare, using mechanical structure relative to servo adjustment structure its cost is relatively low.Phase
Corresponding locking device can be saved by being higher than vehicle centroid height for traditional mechanical leveling structure rotary axis system Partial Height
Design so that structure is simple, reliability and operability increase.And the corresponding levelling device of each axle facilitates its knot
Structure guarantees measurement accuracy to the heart.
Detailed description of the invention:
Attached drawing 1 is normality structural schematic diagram of the invention;
Attached drawing 2 is support base structural schematic diagram of the invention;
Attached drawing 3 is schematic diagram of the present invention under inclined work state;
Attached drawing 4 is present invention schematic diagram when testing stand level when being open to traffic;

Wherein: 1, support base 2, swing arm structure 3, rotary axis system 4, vehicle wheel load measuring instrument 5, cylinder spacer pin
6, arc-shaped limit hole.
Specific embodiment:
Embodiment 1:
One kind being used for vehicle wheel load self-level(l)ing overturn-preventing support device, and composition includes: support base 1, the device pedestal
Upper end is equipped with rotary axis system 3, and the rotary axis system connects swing arm structure 2, and the survey of vehicle wheel load is equipped on the swing arm structure
Instrument 4 is measured, there is a cylinder spacer pin 5 in the swing arm side, across the arc-shaped limit hole 6 of support base when installation.
Embodiment 2:
According to described in embodiment 1 a kind of for vehicle wheel load self-level(l)ing overturn-preventing support device, the device pedestal two sides
There is arc-shaped limit hole 6 in face, and arc-shaped limit hole can cooperate with the cylinder spacer pin on swing arm structure is limited in amplitude of fluctuation
Within ± 12 °.When experiment porch is when tilting within ± 12 °, swing arm structure moment under wheel gravity effect keeps phase
For ground level.
Embodiment 3:
According to described in embodiment 1 a kind of for vehicle wheel load self-level(l)ing overturn-preventing support device, the rotary axis system position
It puts and is higher than actual vehicle height of center of mass position, position will lead to lower than vehicle centroid height and be produced from after certain drift angle occurs
Rotation movement causes device to destroy dangerous with other so that device topples.
Embodiment 4:
According to it is described in embodiment 1 it is a kind of be used for vehicle wheel load self-level(l)ing overturn-preventing support device, when use, is placed on corresponding
On measuring table, according to parameters such as the wheel numbers, wheelspan, wheelbase of measured vehicle, each axle is one corresponding, selects corresponding knot
The quantity of structure is installed and is adjusted by the strip hole of the support base.Vehicle is compensated by corresponding ground level and is filled
The middle position that can be driven into platform and be parked in wheel load measuring instrument is set, platform slowly leans forward, and swing arm can be delayed automatically by gravity
Slow-speed is dynamic, and the vehicle wheel load measuring instrument moment is made to keep parallel to the ground, can automatic leveling vehicle wheel load measuring instrument and moment guarantor
The flat working condition of water holding.
