Portion is provided with the third recessed portion being used cooperatively with second cylinder 4052.
It should be noted that in the prior art loading module be it is fixed, no matter what kind of crooked radian is vehicle bridge 300 have become
Change, loading component can only move up and down, the distance between two loading components be it is fixed, displacement, therefore bending will not be generated
Vehicle bridge 300 itself can generate interference apply component force, be easy to happen movement interference.And the technical program is due to the first lower die
Plane is set as at the top of block 4043, therefore the first cylinder 4042 can be mobile on the surface of the first lower module 4043, works as force section
When part 400 applies downward power, vehicle bridge 300 can generate reclinate small radian, while the first upper module 4041 and first
Main body, which can only move up and down, will not generate displacement, but the first lower module 4043 can be to the direction of the second loading module 405 mobile one
Section distance, shortens the distance between the first lower module 4043 and the second lower module 4053, slows down vehicle bridge 300 itself to application 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 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 loading module, and axis body 403 is by oil cylinder 401
Power be transferred to loading module；Its central axis 403 is traditionally arranged to be optical axis.
It should be noted that being provided with displacement sensor on axis body 403 or loading 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, power needed for test is provided, and by the size of 402 feedback force of force snesor, it is 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 be realized loading direction required by standard and constraint condition, while can guarantee that movement does not interfere.
Further, the first flexural pivot 408, the force snesor 402 and the axis body are connected at the top of the oil cylinder 401
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 optinal plan, the clamping device 200 includes bracket 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 bracket 201, guarantee axis
Body 403 is mobile in vertical direction always.
Further, 203 bottom of 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 are adjustable, 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 and frame body are rotatablely connected, 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 passes through long pore structure and fixed 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.
In conjunction with can be seen that vehicle bridge experimental provision provided in this embodiment to the detailed description of the utility model above, by
Be in loading module in the prior art it is fixed, when force application part 400 exerts a force, vehicle bridge 300 has a reclinate small arc
Degree, but two loading modules will not generate displacement under the action of force application part 400 at this time, therefore be easy to happen movement interference.
And the application is when in use, force application part 400 applies pressure to vehicle bridge 300 by loading module, due to the during force
Two cylinders 4052 are limited by the second recessed portion and third recessed portion, therefore the second loading module 405 can not move；Under first
Plane is set as at the top of module 4043, therefore the first cylinder 4042 can be mobile on the surface of the first lower module 4043；It is exerting a force
Process, since vehicle bridge 300 has a reclinate small radian, the first lower module 4043 can be to the second loading module 405
The mobile a distance in direction, although vehicle bridge 300 is bent downwardly, between the first lower module 4043 and the second lower module 4053
Apart from the technical issues of also being shortened, therefore alleviating movement interference, avoid vehicle bridge 300 by additional power or torque.
