Description

Front hub test repeated bend test fixture
Technical field
The utility model relates to wheel hub test repeated bend test fixture.
Background technology
Car is in actual travel process, because the load of front hub is moment of flexure and the vertical force forming from side force, therefore front hub mainly bears the side force (directions X) that turns to ground contribution, the vertical impact load (Z direction) that suspension is improved quality and ground causes.Simulating vehicle shop experiment is crossed range request and according to entrucking mode, front hub assembly is fixed on fixture, this fixture requires to simulate two load of the actual directions X being subject to of front hub and Z direction simultaneously, and the load of actuator output is accurately transmitted on front hub by fixture, reproduce the actual motion state that front hub is set out on a journey and tried at car load.
Existing tire simulation load plate as shown in Figure 1, its top A connects wheel hub, bottom B connects loader, it is difficult to determine Plumb load position, because tire radius is larger, one end that side direction loads from the center of tire away from, in the process that side direction loads, tire simulation load plate is easily out of shape, so need to increase tire and simulate the rigidity that the thickness of load plate increases load plate, further also increase actual loaded plate weight, more much bigger than the load of actual Plumb load like this, this is a kind of non-real vehicle emulation mode, do not reach the effect of real vehicle simulation, to try the result difference of real train test very large test and actual road.
Utility model content
The purpose of this utility model is to provide a kind of front hub test repeated bend test fixture, to meet simulating vehicle shop experiment demand.
For realizing described object front hub test repeated bend test fixture, the front hub and the steering knuckle that for clamping, link together, be characterized in, comprise that tire simulation fixture, Plumb load fixture, side direction load fixture, control arm bulb stationary fixture, vibration damper simulation fixture, ball pivot stationary fixture and ball pivot part; Tire simulation fixture is polygon, be fixedly connected with front hub, at the fixing Plumb load fixture of the upper side edge of tire simulation fixture, in the lower side fixation side of tire simulation fixture to loading fixture; Control arm bulb on control arm bulb stationary fixture and steering knuckle is fixed, vibration damper simulation fixture lower end is fixed on steering knuckle, upper end is fastened on stationary fixture with described ball pivot part, and control arm bulb stationary fixture and ball pivot stationary fixture are separately fixed on pillar.
Described front hub test repeated bend test fixture, its further feature is that described tire simulation fixture is octagon.
Described front hub test repeated bend test fixture, its further feature is, Plumb load fixture comprises base plate and the web joint projecting upwards in the middle of base plate, after the upper side edge laminating of described base plate and described tire simulation fixture, with bolt, is connected, and described web joint is used for connecting loader.
Described front hub test repeated bend test fixture, its further feature is, side direction loads fixture and comprises base plate and from the middle outstanding web joint downwards of base plate, after the lower side laminating of described base plate and described tire simulation fixture, with bolt, be connected, and described web joint is used for connecting loader.
According to the warranty test result accuracy to a great extent of wheel hub repeated bend test fixture in embodiment of the present utility model, reduce the cost of pilot development, shorten the product testing cycle, reduce human and material resources and property easy for installation while installing.Tire simulation fixture is considered at tire radius place simultaneously and side direction (Y-direction) and vertical (Z-direction) of two positions of wheelspan load, and improves product test capability fast.
