The mapping of employing experience, analogy method for designing design vehicle frame in the commercial car vehicle carriage exploitation at present; Examine, assess vehicle frame by the examination of skid pad road and user's service test, wait until that test and use expose, find defective, modification design again, improvement improve, improve vehicle frame.This exploitation vehicle frame method, used cycle are long, vehicle frame product development cost height.Therefore invent a kind of automobile frame torsion rig of indoor use, steam supply car designer researches and develops to use and is highly profitable.At present domestic indoor chassis torsion testing table and corresponding test method and the standard of yet there are no.Open day be on September 7th, 2005, Granted publication number for though the utility model patent of CN1664529A discloses a kind of torsional strength test stand for motorcycle carriage, the chassis torsion strength test platform of this structure is not suitable as the automobile frame torsional strength test stand and uses.Therefore inventing a kind of automobile frame torsion rig is highly profitable with the needs that satisfy various automakers.
Summary of the invention
Goal of the invention of the present utility model is in order to solve skid pad road examination in the product design of commercial car vehicle frame, the pilot development and this test period of user's service test is long, cost is high test method, and a kind of automobile frame torsion rig is provided.
The technical solution of the utility model is achieved in that it comprises front hung holder and rear suspension device, it is characterized in that: the connection support in the front hung holder is fixed on the false front spring spring, false front spring spring is fixed on the false propons, and the central bottom of false propons is movably articulated in the centre of twist supporting by rotation axis; Connection support in the rear suspension device is fixed on the false rear spring, and false rear spring is fixed on the false back axle, the pipe-hanging hook that suspends after being equipped with on the false back axle, and an end of false propons is equipped with a force loading device.Described force loading device comprises a displacement force sensor that is connected with actuator hlydro-cylinder and swing rocking bar, is movably hinged by the culdy arm between displacement force sensor, swing rocking bar and the false propons three; The two ends of the described false back axle balancing weight that suspended, after suspend pipe-hanging hook by two unsteady Screw rod bearingses.
The utility model, it can simulate Uneven road, the dislocation washboard road formula pit (or groove) that the commercial car vehicle frame bears and cause and reverse the damage environmental model when finishing transportation function on the shop experiment stand, accomplish early stage exposure, find the vehicle frame defective, reach and shorten the commercial car vehicle frame test period, reduce the purpose of R﹠D costs.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1 and Figure 2, the utility model comprise fixing vehicle frame 7 before suspend and connect support 3 and be fixed on the false front spring spring 2, false front spring spring 2 is fixed on the false propons 4, and the central bottom of false propons 4 is movably articulated in the centre of twist supporting 1 by rotation axis; After suspend and connect support 15 and be fixed on the false rear spring 12, false rear spring 12 is fixed on the false back axle 13, pipe-hanging hook 10 suspends after being equipped with on the false back axle 13.One end of false propons 4 is equipped with a force loading device, and described force loading device comprises a displacement force sensor that is connected with actuator hlydro-cylinder 98 and swing rocking bar 5.Be movably hinged by culdy arm 6 between displacement force sensor 8, swing rocking bar 5 and false propons 4 threes; As shown in Figure 3, the two ends of described false back axle 13 balancing weight 16 that suspended; After suspend pipe-hanging hook 10 by two unsteady screw rods 11 and 14 supportings.
During test, suspend before vehicle frame 7 is fixed on connect support 3 with after suspend and be connected on the support 15, false propons 4, false front spring spring 2 and before suspend that to connect support 3 (actual functional capability is distant bar) be for the stressed carrying shape of mounting support Indistinct in the actual use of simulating vehicle, its objective is for make indoor stand more the real simulation vehicle when finishing transportation function, carry stressed function; Displacement scaling culdy arm 6 is to design displacement to load enlarger for the little displacement of adaptive actuator hlydro-cylinder, and purpose makes little cylinder displacement also can adapt to the requirement of the big torsional angle of chassis torsion, high pulling torque, big displacement in order to reduce the displacement of load cylinder; Swing rocking bar 5 is to load the moving displacement interference and the space displacement interference of purpose elimination load cylinder and false propons twisting motion is set in order to eliminate displacement convergent-divergent culdy arm 6; The setting of centre of twist supporting 1 is in order to simulate the real vehicles propons centre of twist.The balancing weight 16 that produces reaction torque and torsional angle be suspended in float screw rod 11 and unsteady screw rod 14 and after suspend on the pipe-hanging hook 10, its objective is and floated in the top to bottom, left and right, front and rear of vehicle frame when torsional deflection, not interfered by torsional deflection, the stress raisers of testing table installation position in the decontamination chamber.Wherein balancing weight 16 can add deduct, so that the requirement of the reaction torque of convenient and suitable commercial car different model, different size, different tonnage vehicle frames, torsional angle and simulation monovalence torsion mode.False back axle 13 and false rear spring 12 and after suspend that to be connected support 15 are simulating vehicle true supporting and force-bearing situations in finishing the transportation function use, make indoor bench test real simulation user environment for use stress model.
As shown in Figure 1, electrohydraulic servo valve or solenoid valve receive the test electric signal in the electrical control cubicles that the testing crew adjusting is provided with, that testing table adds moment of torsion, torsional angle and reinforcing, displacement on the actuator hlydro-cylinder 9, regulate oil pressure or atmospheric pressure, make actuator produce power or displacement action, make false propons 4 around centre of twist supporting 1 rotation through displacement scaling culdy arm 6, make vehicle frame positive and negative (left and right) reversed torsion distortion, carry out the torsional fatigue life test.
Shown in Fig. 2,3, the passive reaction torque that suspends behind the simulated frame is provided by balancing weight 16, and for the requirement of adaptive commercial car different model, tonnage, big trolley frame (reversing) rigidity and all torsion modes, balancing weight 16 can increase and decrease.By float screw rod 11 and unsteady screw rod 14 and after the pipe-hanging hook 10 that suspends be provided with, make its Cheng Zai And that reaction torque and retroaction torsional angle are provided, can eliminate about chassis torsion when distortion, up and down, the test vibration deformation of front and back interferes, the stress raisers at the mounting support position in the decontamination chamber during testing table assembly unit.Vehicle frame in making that indoor vehicle frame testing table analog subscriber is actual and using is truly stressed, distortion, damage, damage operating mode.
