Abstract
The utility model discloses a kind of suspension system fatigue tester, it includes board, the balladeur train being arranged in parallel in above board and two groups of torque load maintainers；Described two groups of torque load maintainers one end is disposed on the balladeur train, and the both ends for the suspension bridge being upside down on the board are fixed on after the vertical relative tilt of the other end.Compared with prior art, a kind of suspension system fatigue tester of the utility model, it is simple in structure, torque load maintainer only by setting two groups of vertical relative tilts to set, realize that vertical, transverse direction and heeling moment load bear suspension system the simulation test of load, suspension system can be tested in the case of with heeling moment load, be better able to the performance of actual response suspension system, be conducive to improve the quality and safety of detected suspension system.
Description
【Technical field】
The utility model belongs to automobile making detection technique field, more particularly to a kind of suspension system fatigue tester.
【Background technology】
Suspension system is the attachment device of all power transmissions or torque between the vehicle frame of automobile and vehicle bridge or wheel, its fatigue
Performance can be most important to vehicle security.However, the country is also without ready-made test-bed, test method and standard pair at present
Suspension system carries out the fatigue test method and mark of fatigue property test, the only component such as air spring, stabiliser bar and distance rod
It is accurate.Therefore, the fatigue behaviour of suspension system is generally detected by proving ground test.During proving ground test, in suspension system
When early fracture failure occurs in some component, general designer can only be according to road test as a result, improving the fatigue of problem component
Characteristic, then proceedes to proving ground test.Not only experimentation cost is high for this method, cycle length, and it is whole to be unfavorable for airsuspension system
The improvement of body fatigue behaviour.
For this reason, China Patent No. is a kind of experiment for Air Suspension for Commercial Vehicles system disclosed in 201610401796.0
Rack, but the testing stand is detected suspension system opplied moment not in the case of with heeling moment, and suspension
System can be subject to different degrees of heeling moment to act on during actual use, also suitable to suspension opplied moment
It is important, and there is presently no a kind of dress that can be detected in the case of with heeling moment to suspension opplied moment
Put.
【Utility model content】
The main purpose of the utility model is that providing a kind of suspension system fatigue tester, set by incline direction
Two groups of torque load maintainers, simulate all directions of the suspension system during the examination of actual drive test and integrate stressing conditions, detection
The rigidity property and fatigability of suspension system, it is simple in structure, it is easy to operate, meet test requirements document.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of suspension system fatigue tester, it includes
Board, the balladeur train being arranged in parallel in above board and two groups of torque load maintainers；Described two groups of torque load maintainer one end interval
It is arranged on the balladeur train, the both ends for the suspension bridge being upside down on the board is fixed on after the vertical relative tilt of the other end.
Further improved as the utility model, the angle of inclination is 15 °.
Further improved as the utility model, two groups of torque load maintainers are socketed in the balladeur train by sliding block
On, it is locked after being relatively moved along the balladeur train.
It is further improved as the utility model, the both ends of the torque load maintainer respectively with the sliding block, described
Suspension bridge end is hinged.
Further improved as the utility model, the torque load maintainer includes hydraulic cylinder；The hydraulic cylinder
Cylinder body end be articulated with the sliding block, piston end, which is articulated with, to be fixed on the contiguous block of the suspension bridge end
Compared with prior art, a kind of beneficial effect of suspension system fatigue tester of the utility model is：Structure letter
It is single, only by the torque load maintainer for setting two groups of vertical relative tilts to set, that is, realize vertical, transverse direction and heeling moment load
The simulation test of load is born to suspension system, suspension system can be carried out in the case of with heeling moment load
Experiment, is better able to the performance of actual response suspension system, is conducive to improve the quality and safety of detected suspension system
Property.

【Embodiment】
Embodiment：
Fig. 1 is refer to, the present embodiment is a kind of suspension system fatigue tester, it includes board 1, is arranged in parallel in board
The balladeur train 2 and two groups of torque load maintainers 3 of 1 top；Described two groups of torque load maintainers, 3 one end is disposed on balladeur train 2, separately
The both ends for the suspension bridge being upside down on board 1 are fixed on after the vertical relative tilt in one end.
Two groups of torque load maintainers 3 are socketed on balladeur train 2 by sliding block 4, according to suspension system different in width to be tested
Specification, makes sliding block be locked after being relatively moved along balladeur train 2, improves the accommodation of testing machine.
Torque load maintainer 3 includes hydraulic cylinder；The cylinder body end of hydraulic cylinder is articulated with sliding block 4, and piston end is articulated with
Be fixed on the contiguous block 5 of 6 end of suspension bridge, through studying for a long period of time experiment, hydraulic cylinder vertical angle of inclination be 15 °
When, the performance of test data more actual response suspension system.
Main body 41 that the sliding block 4 includes being socketed on balladeur train 2, the vertical connecting plate 42 for being arranged on bottom part body and fixed
Articulated slab 43 on vertical connecting plate 42；There is multigroup mounting hole 44, articulated slab 43 can be according to waiting to try on vertical connecting plate
The suspension system different height specification tested, on the mounting hole 44 of vertical 42 different height of connecting plate, improves testing machine
Accommodation.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality
