Description
Technical field
The present invention relates to a kind of car white vehicle body structure torsional rigidity test constraint and loading equipemtn, belong to the automobile product technical field of measurement and test.
Background technology
Torsional rigidity is one of car white vehicle body structure performance that must satisfy.In the passenger car product development process, must carry out the test of torsional rigidity by the dialogue body structure, whether satisfy the torsional properties requirement to estimate the body in white structure of being developed.Therefore, body in white construction torsion rigidity testing system is an exploitation passenger car product imperative equipment.Constraint is a body in white construction torsion rigidity testing system major equipment with charger." automobile intensity " and Liu Weixin chief editor in that Japanese car technological associations compile have proposed car white vehicle body structure torsional rigidity test constraint and the basic demand that loads in the books such as " Automobile Design " that publishing house of Tsing-Hua University publishes.These basic demands are:
(1) fixing body tail, the ordinate of fixed position is the rear shaft center position, applies moment of torsion in the perpendicular at front axle center line place;
(2) rigidity of its restraint device and charger can not exert an influence to test result.
But all do not relate to following content in the above-mentioned data:
(1) the concrete constrained procedure of car white vehicle body structure torsional rigidity test and the concrete structure of restraint device;
(2) the concrete loading method of car white vehicle body structure torsional rigidity test and the concrete structure of charger;
Though the constrained procedure of some motor corporation's test body in white torsional rigidities in some other country as Japan and Europe is basic identical in the world, but what restraint device adopted all is the unit clamp of developing at different automobile types, this just means that vehicle of every test all needs to develop the special-purpose restraint device of a cover, that is to say if test the torsional rigidity of Citroen zx and these two kinds of cars of Santana, though be car equally, but still need the different restraint device of exploitation two covers, so this method because of time-consuming, take a lot of work and not have the versatility cost higher.
Aspect loading method, these companies are also basic identical, promptly adopt general fluid pressure type to put forth effort device and produce power, power are delivered to the position of stipulating on the body in white by force transfer mechanism.General fluid pressure type is puted forth effort device and not only be can be used for testing the body in white torsional rigidity, also can be used for other test, but general fluid pressure type puts forth effort device and cost an arm and a leg, and a fluid pressure type that can be used for body in white construction torsion rigidity test is puted forth effort the device price about 300,000 Renminbi.Force transfer mechanism is the same with restraint device simultaneously, need develop specially at different automobile types equally.

Embodiment
This device comprises restraint device and the charger two parts that are fixed on the worktable, further specifies concrete structure of the present invention and optimal way below in conjunction with accompanying drawing:
One, restraint device: as shown in Figure 1 and Figure 2, this device is made up of left and right sides rear support 4,6 and link 3,7.Rear suspension upper support position, the left and right sides on the vehicle body joint face of vehicle body (the suspension top with) is connected with bearing by link, and link 3,7 can adopt and only allow vehicle body around the hinge that rotates by the X-axis of tie point.Left and right sides rear support 4,6 is fixed on the T type worktable of adjustable solidating allocation, by adjusting the fixed position of left and right sides rear support, can adapt to different vehicles.
Two, charger:: as shown in Figure 3, this charger is puted forth effort device by adjustable force transfer mechanism and screw mandrel formula and is formed.Bearing 1 adopts and is bolted to the purpose that can realize adjusting the fixed position on the T type groove worktable, adopts hinge 14 as the web member of the arm of force 5 with bearing 1, and the arm of force 5 is connected with bearing 1 in the center, and the Y-axis that allows the arm of force to walk around tie point is rotated.
The link 8,11,9 of left/right adjustable connecting rod and the arm of force 5 and vehicle body and 10 adopts the unitized construction of hinge and oscillating bearing.The arm of force 5 is connected with left/right adjustable connecting rod lower end with 11 by link 8, front suspension upper support position on the body in white 2 joint face of front suspension summit (vehicle body with) is connected with the left/right adjustable small end with 10 by link 9, the arm of force, left/right adjustable connecting rod and vehicle body have just formed a parallelogram four-bar linkage like this, and this parallelogram is positioned at the perpendicular at automobile front-axle center line place; Because the effect of oscillating bearing can be rotated the left/right adjustable connecting rod around tie point, the rigidity that reaches charger does not influence the purpose of test result.
From Fig. 4 and Fig. 5 as can be known, adjustable connecting rod mainly by the feed screw nut 15,18 of band oscillating bearing, form by lock-nut 16,17 and screw axis 19.The screw pair mechanism that forms by feed screw nut 15,18 and screw axis 19 can adjust the length of adjustable connecting rod, and lock-nut 16,17 plays regular length.As can be seen from Figure 6, on the arm of force 5, be provided with left and right sides chute 20, can axially adjust the fixed position of adjustable connecting rod by chute 20 along the arm of force 5.Just can reach the purpose that adapts to different automobile types by length and the fixed position of left/right adjustable connecting rod on the arm of force of adjusting adjustable connecting rod.
As can be seen from Figure 7, the screw mandrel formula is puted forth effort device and is comprised by the screw pair formed of screw axis 22 of feed screw nut 21 and band handle 23, is connected bindiny mechanism, the strain force sensor of screw axis and strain-type force sensor 25 and links up with 26 and form.When rotation was welded on handle 23 on the screw axis 22, screw axis 22 moved downward.Adopt hinge 12 and hook 26 to put forth effort the web member of device as the arm of force 5 and screw mandrel formula, put forth effort device at a certain end of the arm of force with the screw mandrel formula and be connected, employing hinge 13 is puted forth effort device with the screw mandrel formula and is fixed on the T type groove worktable, and its point of fixity position can be adjusted.When screw axis 22 moves downward, make the arm of force bear downward pulling force by hinge 12, utilize lever principle to pass through parallelogram four-bar linkage, form a moment of couple and be applied on the vehicle body, thereby realized the purpose that loads.
As can be seen from Figure 8, screw axis 22 is connected with steel framework 24 by the axial thrust bearing 27 in the bindiny mechanism, steel framework 24 in variant force cell 25 and the bindiny mechanism adopts bolts to be connected, so just effectively avoided when screw axis rotates, steel framework and connected strain-type force sensor rotate with screw axis.
