Description
Technical field
The invention belongs to vehicle testing equipment technical field, and in particular to during a kind of car white vehicle body torsional rigdity test
The loading device used.
Background technology
At present, the force snesor of ordinary passenger car white body torsion stiffness loading device for testing is usually placed in front suspension about
On beam fixture.During loading, the moment values of required loading need to all be scaled corresponding force value before on-test.Power needed for conversion
The measurement of arm, often because deviation occurs for people, instrument, influences experimental result.Meanwhile the implementation of moment of torsion will be constrained by front suspension and pressed from both sides
Tool is delivered on white body, and the installation of left and right front suspension constraint fixture cannot be guaranteed absolute symmetry, by being arranged in front suspension about
The implementation of force snesor control mode on beam fixture, in addition to required moment of torsion, also tends to be attached other load, to experiment
As a result accuracy can also have an impact.In addition, under the conditions of above-mentioned clamping, the requirement to force snesor will except installation dimension
It is small, there is load range to be greater than 10000N, to ensure safety.
The content of the invention
The present invention intends providing a kind of ordinary passenger car white body torsion stiffness loading device for testing, suitable for ordinary passenger car
It is control accuracy higher, easier and similar vehicle uses, influence of the fixture to test result can be reduced, white body moment of torsion adds
Carried convenient, torque are accurate, can follow-on test, forward and reverse test, and shorten the white body torsion stiffness testing time.
For this reason, the technical solution adopted in the present invention is：A kind of ordinary passenger car white body torsion stiffness test loading dress
Put, including test platform, and the rotation tee girder on test platform, two front suspensions constraint fixtures are between left and right every peace
On the horizontal beam of rotation tee girder, two rear suspensions constrain fixture between left and right every on test platform, its feature exists
In：The extending bracket being sequentially connected from top to bottom, upper hinge connecting seat, force snesor, loader and base are further included, it is described to prolong
Stretch the fixing point distance rotation tee girder of horizontal beam one end that stent is installed in rotation tee girder, upper hinge connecting seat and extending bracket
The transverse horizontal distance L of rotation axis be 1000mm, the connection of the upper and lower ends of the force snesor is flexural pivot, and possesses power
It is worth display function, the loader can realize that stablizing for bulk increases or reduce in vertical direction, so as to drive common
Car white vehicle vehicle body is reversed or reversed counterclockwise clockwise around the rotation axis of rotation tee girder.
In such scheme, a kind of preferred embodiment of loader is：The loader includes being sequentially connected down from top to bottom
Hinge connecting seat, upper arm, pull rod and the lower arm of force, two upper arms and two lower arm of forces are arranged on lower hinge connecting seat and base
Between and surround telescopic diamond shape, be hinged on together positioned at the lower end of the upper arm in left side and the upper end of the lower arm of force positioned at left side
In one nut pin, it is hinged on positioned at the lower end of the upper arm on right side and the upper end of the lower arm of force positioned at right side in another nut pin,
Two nut pins are installed on using different rotation directions on the left and right termination of pull rod.
Further, two upper arms are hinged on lower hinge connecting seat by the spaced hinge joint in left and right, and two
A lower arm of force is hinged on base by the spaced hinge joint in left and right.
Another preferred embodiment of loader is：The loader realizes vertical direction overhead using leadscrew-nut mechanism
Between size stablize increase or reduce.
The beneficial effects of the invention are as follows：
(1) upper hinge connecting seat and the transverse horizontal distance of rotation tee girder rotation axis keep 1000mm, can very easily
Shown by the force value of force snesor, it is accurate to apply the common moment values of ordinary passenger car white body torsion stiffness test：1000Nm、
2000Nm, 3000Nm, 4000Nm etc., i.e., the force value that need to only pay close attention to force snesor are shown as 1000N, 2000N, 3000N, 4000N
Deng, lacked conversion link, loading it is more accurate.
(2) loading device can realize that stablizing for bulk increases or reduce in vertical direction, ensure ordinary passenger car
The test of white body torsion stiffness can be torsion clockwise or reverse counterclockwise, moreover it is possible to allow process during test with behaviour
The rhythm of control person is fast or slow.
(3) clamping of the white body on testing stand, because being put by force snesor, position is fixed, the whole white car of ordinary passenger car
The loading of moment of torsion is no longer constrained fixture by left and right front suspension and white body installation is influenced when body torsion stiffness is tested, and makes equipment
Precision gets a promotion.
(4) clamping of the white body on testing stand, it is not direct to have an effect with force snesor, meanwhile, by force snesor
Put, requirement of the whole ordinary passenger car white body torsion stiffness test to the installation dimension, load range of force snesor is significantly dropped
It is low.
(5) in order to ensure the implementation of loading, in the range of equipment precision requirement, the connector that is vertically connected with of force snesor is adopted
With flexural pivot, equipment is can be adapted for larger range of reverse and load.
