Abstract
The utility model relates to a suspension ball pivot assembly endurance test device, by base, swing arm, connecting rod、The rotor arm and spring loader constitute, its characterized in that: the swing arm and the base are connected through a shaft, and the connecting rod and the swing arm are connected through a test spherical hinge to form a parallelogram mechanism; two ends of the connecting rod are both provided with spherical hinges, one swing arm end is connected with the universal displacement loading mechanism, and the other swing arm end is connected with a spring loader. One end of the rotating arm is fixed on the connecting rod and can rotate around the central line of the connecting rod, and the end part of the rotating arm is connected with another displacement loading mechanism. The suspension spherical hinge assembly is installed by adopting a parallelogram four-bar linkage mechanism, and the synchronous swinging and rotation of the suspension spherical hinge assembly are realized while the load loading is realized by matching two universal linear actuators. The loading problem of suspension ball pivot assembly in complicated space motion process is solved, make bench test more approach the actual use condition of sample, improved the accuracy of test result. When avoiding using special test bench, promoted test efficiency, reduced test cost.
Description
Technical field
The utility model relates to a kind of suspension ball pivot assembly durability test apparatus, is applicable to the stand long duration test of the cross-country vehicle steeraxle of employing independent suspension with suspension ball pivot assembly, belongs to automobile chassis parts bench test technology.
Background technology
The stand long duration test mechanism that is directed against suspension ball pivot assembly at present can only apply folk prescription to suspension ball pivot assembly and examine its endurance life to load.And the ball pivot assembly is in the actual applying working condition of car load; Because the complicacy of steering motion; The size and Orientation of the load of being transmitted all is a spatial variations; The wearing and tearing that the actual applying working condition, particularly spatial movement that the obvious load that in stand long duration test mechanism, can only apply single direction can not be reacted suspension ball pivot assembly causes.
Summary of the invention
The purpose of the utility model is to provide a kind of suspension ball pivot assembly durability test apparatus; Adopt parallelogram four-bar linkage to realize the installation to suspension ball pivot assembly, two the general linear actuators of arranging in pairs or groups are in the synchronous swing and the rotation that realize realizing when load loads suspension ball pivot assembly.
The technical scheme of the utility model is achieved in that suspension ball pivot assembly durability test apparatus, by base, swing arm, connecting link
,Swivel arm and spring-loaded device are formed, and it is characterized in that: adopt axle to be connected between swing arm and base, be connected with testing ball pivot between connecting link and swing arm, constitute a parallel-crank mechanism; The connecting link two ends all are ball pivot, connect general displacement load maintainer at a swing arm end, connect a spring-loaded device at another swing arm end, and swivel arm one end is fixed on the connecting rod, can rotate around the connecting rod center line, connect another displacement load maintainer in the end.
The good effect of the utility model is to have solved the loading problem of suspension ball pivot assembly in the complex space motion process, makes bench test more near the actual operating position of sample, has improved accuracy of experimental results.Adopt general linear actuator as load maintainer and can realize the test examination of two suspension ball pivot assemblies simultaneously, when avoiding the use of special-purpose testing table, promoted test efficiency, reduced experimentation cost.
Description of drawings
Fig. 1 is this suspension ball pivot assembly long duration test mechanism synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: as shown in Figure 1, suspension ball pivot assembly durability test apparatus is by base 1, swing arm 2, connecting link 3
,Swivel arm 4 and spring-loaded device 5 are formed, and adopt general linear actuator 7 to load; It is characterized in that: 1 of swing arm 2 and base adopt axle to be connected, and 2 of connecting link 3 and swing arms are connected with testing ball pivot 6, constitute a parallel-crank mechanism; Swing arm 2 ends that connect in actuator apply a displacement load, and swing arm 2 is swung to another side.Mechanism produces motion deformation, and because of opposite side remains parallelly, then ball pivot produces the pivot angle that the pendulum angle size with swing arm 2 equals.Other end swing arm 2 is also swung under deformation; And promotion spring-loaded device 5 motions; The spring of spring-loaded device 5 acts on parallel-crank mechanism because of distortion produces reacting force, thus the loading that the reacting force that utilizes spring that mechanism is produced comes realizable force.In like manner, when actuator to motion in the other direction be mechanism when opposite direction swung, the loading of same reacting force realizable force by spring.In said process, get actuator at swivel arm 4 ends and apply shift reciprocately load, swivel arm 4 and connecting link 3 are rotated around the two ball pivot lines of centres, thereby realize the rotation of ball pivot around axis.Then can realize the rotation of connecting link 3 simultaneously at above-mentioned motion process around axis.In sum, this test mechanism is realized the synchronous swing and the rotation of suspension ball pivot assembly when two general linear actuator realizable force load of collocation load.
