The beveling suspension spiral spring fatigue test device has the beneficial effects that according to a beveling suspension spiral spring fatigue test machine, the real stress condition of a suspension spring in the displaying and using process can be really simulated, the test is different from the conventional linear fatigue endurance test, and the test machine can realize nonlinear spring reciprocating; and moreover, because the comprehensive stress conditions of the product are changed, the comprehensive stress is more than that borne by a linear spring during test; and therefore, a high-strength test and an acceleration test can be performed.
Description
Technical field
The utility model belongs to the fatigue test device field, especially relates to a kind of inclined cutout suspension fork screw spring fatigue experimental device.
Background technology
Domestic spring testing machine product carries out the up and down reciprocal long duration test of linear pattern to volute spring along the damper shaft line position mostly at present, and real volute spring in use, not only bears acting force up and down, also wants
BearBe subject to the tractive force of other directions or the component of damping force direction.
In the past volute spring fatigue tester is mechanical type in the existing technology, is to connect the offset cam drivening rod by motor, reductor to move reciprocatingly, and realizes the linear pattern compression movement to spring.Can adjust according to the requirement of experiment of spring amplitude and the test frequency of spring.And the functions such as default test number (TN) and fracture shutdown.This kind testing machine can realize that the straight line of spring product simulates up and down tiring exercises, but a lot of situation lower suspension springs are in use except bearing the weight of vehicle perpendicular to ground, component on other directions such as the tractive force direction that other devices produce around also will bearing or damping force direction, for example, owing to the tractive force direction of braking or accelerating to produce or the component on the damping force direction.Therefore real bearing spring in use is not the motion of doing fully straight up and down, but a kind of compound multidirectional power motion.Be reflected on the product then is that volute spring is subject to the bonding force on the non-central axis.Therefore, the linear pattern fatigue tester can not truly reflect the behaviour in service of suspension fork screw spring.The automobile suspension damping spring, as the important component part of car shock mitigation system, the quality in its performance and life-span has directly affected driver's handling and riding comfort.The bearing spring fatigue tester as check and check volute spring product fatigue durability can Key Experiment equipment, whether it can distortion situation and the mode of motion of real simulation spring under true road conditions, is the necessary experimental project to the spring performance guarantee.Existence detect when can't carry out the amplitude detecting of acting force up and down to spring the tractive force that is subject to other directions or damping force direction component carry out the technical matters such as testing fatigue.This kind is comprehensive stressed, and the traditional experiment machine can not satisfy.
Summary of the invention
Problem to be solved in the utility model provides a kind of spring and is subjected to testing a machine of vectorial force direction-agile, it is variable when this kind testing machine requires the spring stress direction along with the carrying out of time cycle, but maximum amount of spring compression and be subjected to force direction with requirement of experiment is consistent, especially suitable inclined cutout suspension fork screw spring fatigue experimental device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model comprises upper spring seat, lower spring cup, connecting link, offset cam, belt, motor, and connecting link is connected with eccentric cam shaft; Spring is between upper spring seat and lower spring cup; Motor connects the offset cam rotation, drives the connecting link to-and-fro movement; Also comprise swinging mounting and carrier base, swinging mounting one end is connected with the carrier base axle, and the top of the swinging mounting other end is fixedly connected with lower spring cup, and the side of swinging mounting is connected with pitman shaft.
Further, described swinging mounting is length-adjustable support.
Further, described being fixedly connected with is that bolt connects.
Further, described offset cam arranges carrier base.
Further, described motor arranges carrier base.
Further, described connecting link is the capable of regulating connecting link.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, inclined cutout suspension fork screw spring fatigue tester, the real true stressed situation of simulated suspension spring in vehicle traveling process, from the linear pattern fatigue endurance test was different in the past, this testing machine can be realized the to-and-fro movement of spring non-rectilinear, because the comprehensive stressed situation of product changes, combined stress than the linear pattern spring bear at the trial many, therefore can carry out high strength test and accelerated test.Use convenient, have simple in structure, easy to maintenance, the advantage such as processing cost is low.

Embodiment
As shown in Figure 1, the utility model comprises upper spring seat 1, lower spring cup 2, connecting link 3, offset cam 4, belt, motor 5, and connecting link 3 arranges and is connected with offset cam 4 axles; Spring is between upper spring seat 1 and lower spring cup 2; Motor 5 drives offset cam 4 rotations, drives connecting link 3 to-and-fro movements; Also comprise swinging mounting 6 and carrier base 7, swinging mounting 6 one ends are connected with carrier base 7 axles, and the top of swinging mounting 6 other ends is fixedly connected with lower spring cup 2, and the side of swinging mounting 6 is connected with connecting link 3 axles.
Further, described swinging mounting 6 is length-adjustable support.
Further, described being fixedly connected with is that riveted joint, bolt connect.
Further, described offset cam 4 arranges carrier base.
Further, described electronic 5 machines arrange carrier base.
Further, described connecting link 3 is the capable of regulating connecting link.
Inclined cutout suspension fork screw spring fatigue experimental device is really to simulate spring its true stressed situation in vehicle traveling process, from the linear pattern fatigue endurance test was different in the past, this testing machine can be realized the to-and-fro movement of spring non-rectilinear, its design feature is to provide power to drive offset cam 4 runnings by the band motor for speed reducer, connect the capable of regulating connecting link by offset cam 4 again, center on rotation axis by connecting link 3, realize parabolic path motion or the arc track motion of helical spring seat, its direction of motion is variable in time, but the decrement of spring maximum be subjected to the adjustable joint of force direction and requirement of experiment one to.
