4042 the first recessed portions being used cooperatively, first lower module, 4043 top are set as plane；Second load-on module 405
Including the second upper module 4051, the second cylinder 4052 and the second lower module 4053 set gradually from top to bottom, on described second
4051 bottom of module is provided with the second recessed portion being used cooperatively with second cylinder 4052, and second lower module 4053 pushes up
Portion is provided with the third recessed portion being used cooperatively with second cylinder 4052.
It should be noted that load-on module is fixed in the prior art, no matter what kind of crooked radian is vehicle bridge 300 have become
Change, loading component can only move up and down, and the distance between two loading components are fixed, not will produce displacement, therefore be bent
Vehicle bridge 300 itself will produce interference apply component force, be easy to happen movement interference.And the technical program is due to the first lower die
4043 top of block is set as plane, therefore the first cylinder 4042 can move on the surface of the first lower module 4043, work as force section
When part 400 applies downward power, vehicle bridge 300 will produce reclinate small radian, while the first upper module 4041 and first
Main body can only move up and down and not will produce displacement, but the first lower module 4043 can be to the direction of the second load-on module 405 movement one
Segment distance shortens the distance between the first lower module 4043 and the second lower module 4053, slows down vehicle bridge 300 itself to applying component
The technical issues of exerting a force, therefore alleviating movement interference.
Specifically, the force application part 400 includes oil cylinder 401,401 bottom of the oil cylinder connects force sensor 402, institute
It states 402 bottom of force snesor and is connected with axis body 403, the axis body 403 is connect with the load-on module, and axis body 403 is by oil cylinder 401
Power be transferred to load-on module；Its central axis 403 is traditionally arranged to be optical axis.
It should be noted that displacement sensor is provided on axis body 403 or load-on module, and displacement sensor and power sensing
Device 402 is electrically connected with the controller, and the data of force snesor 402 and displacement sensor are recorded by controller；Wherein oil cylinder 401
As force application part 400, the power needed for experiment is provided, and by the size of 402 feedback force of force snesor, intuitively shown by controller
With control force value.The device can be suitable for Drive axle housing vertical curve rigidity, vertical curve test of static strength and vertical curved
Bent fatigue test etc. can realize loading direction and constraints required by standard, while can guarantee that movement does not interfere.
Further, 401 top of the oil cylinder is connected with the first flexural pivot 408, the force snesor 402 and the axis body
The second flexural pivot 407 is provided between 403；The setting of first flexural pivot 408 and the second flexural pivot 407 can ensure oil cylinder 401 only by axis
Xiang Li, to shield to oil cylinder 401.
Further, first lower module 4043 and second lower module 4053 with the spring in vehicle bridge 300
Seat 301 is fixedly connected；First upper module 4041 and second upper module 4051 are fixedly connected with the axis body 403；
Force application part 400 is facilitated to be downwardly applied to power.
It should be noted that first recessed portion and 4042 clearance fit of the first cylinder, facilitate the first cylinder
4042 the first recessed portion inner rotation；Second recessed portion and the third recessed portion with second cylinder 4052
Clearance fit facilitates the second cylinder 4052 in the second recessed portion and third recessed portion inner rotation.
In the present embodiment alternative, the clamping device 200 includes holder 201 and fixture 203, and the fixture 203 presss from both sides
Vehicle bridge 300 is held, since fixture 203 is set as two, so vehicle bridge 300 can be clamped.
Specifically, being provided with the linear bearing 406 playing the guiding role to the axis body 403 on the holder 201, ensure axis
Body 403 is moved in vertical direction always.
Further, 203 bottom of the fixture is provided with idler wheel 202, and the spacing between idler wheel 202 is adjustable.
It should be noted that idler wheel 202 is set as two, i.e., the distance between two idler wheels 202 in left and right can be adjusted, by
Must be equal with the wheelspan of automobile in the distance between two idler wheels 202 in left and right, therefore the present apparatus can be adapted for different model
Vehicle bridge 300 test.
It should also be noted that, idler wheel 202 is rotatablely connected with frame body, frame body is connect with 203 bottom of fixture, due to fixture
203 bottoms are provided with long pore structure, and the bolt on frame body is fixed across long pore structure by nut；When needs adjust left and right two
When the distance between idler wheel 202, it is only necessary to by nut tune pine, then idler wheel 202 is adjusted to nut tune suitably after
It is whole good.
Vehicle bridge experimental provision provided in this embodiment is can be seen that in conjunction with the above detailed description of the present invention, due to existing
Load-on module is fixed in technology, and when force application part 400 exerts a force, vehicle bridge 300 has a reclinate small radian,
But two load-on modules not will produce displacement under the action of force application part 400 at this time, therefore be easy to happen movement interference.And this
When in use, force application part 400 applies pressure by load-on module to vehicle bridge 300, due to the second column during force for application
Body 4052 is limited by the second recessed portion and third recessed portion, therefore the second load-on module 405 can not move；Due to the first lower module
4043 tops are set as plane, therefore the first cylinder 4042 can move on the surface of the first lower module 4043；Force process,
Since vehicle bridge 300 has a reclinate small radian, the first lower module 4043 can be to the direction of the second load-on module 405
Mobile a distance, although vehicle bridge 300 is bent downwardly, the distance between the first lower module 4043 and the second lower module 4053
The technical issues of being shortened, therefore alleviating movement interference avoids vehicle bridge 300 by additional power or torque.
