Background technology
Steering knuckle is the important chassis safety member that connects wheel, brake system and suspension.Bear load and the road surface of deflecting roller and transmit the impact of coming, also bear the steering force from steering gear simultaneously, realize turning function, there is to very high requirement its intensity, impact resistance, fatigue strength and reliability aspect, so stand long duration test is requisite link in steering knuckle design process.
At present, the external technology of the designing and developing comparative maturity to steering knuckle, the larger gap of domestic existence, do not have at present device preferably to carry out durable test to steering knuckle, although there is hydraulic servo fatigue system, there is no corresponding test unit, be difficult to the performance of steering knuckle to analyze.In order to grasp the technology of designing and developing of steering knuckle, the steering knuckle characteristic in real vehicle structure is tested, in conjunction with the theory of automobile dynamics, analyze the working mechanism of intermediate support ring, thereby be badly in need of the durability test apparatus of efficient, reliable steering knuckle.
Utility model content
The utility model provides a kind of durability test apparatus of testing automobile steering knuckle, by hydraulic servo fatigue system, the endurance quality of steering knuckle is tested.
Spindle durability test apparatus of the present utility model, by fixed part, support section and afterburning part, formed, described stationary fixture and exemplar knuckle arm are by installing under real vehicle state, and because the pattern of knuckle arm is more, stationary fixture also will be along with the state of installing changes.
Support section is to load floor to hold hole with steering knuckle spindle to be measured and connect by fastening nut, and the caliper mounting hole on steering knuckle and hub bearing fixed installation hole, fix by the state of wheel on real vehicle and steering knuckle installation by nut.
Loading section is that the start cylinder of hydraulic servo fatigue system loads seat with side direction or loading link connects, by loading floor, loading force is passed on steering knuckle, the load that when simulated automotive travels, tire applies steering knuckle, reaches the object of steering knuckle long duration test.Described side direction loads seat and loads link and connects with the start cylinder of hydraulic servo fatigue system, easy for installation, the at utmost stability of warranty test device and reliability in process of the test, and the labour intensity of minimizing testing crew, increases work efficiency.
The flow process that spindle durability test apparatus of the present utility model is tested is as follows:
1, steering knuckle to be measured is arranged on test-bed by stationary installation, mounting means, is subject to force direction, mode of motion etc. all to need to be consistent with the steering knuckle actual condition of car load.
2, the start cylinder of hydraulic servo fatigue system loads seat or loads link with side direction and connects, while applying side force to steering knuckle to be measured, the start cylinder of hydraulic servo fatigue system loads seat with side direction and connects, while applying vertical force or longitudinal force to steering knuckle to be measured, the start cylinder of hydraulic servo fatigue system connects with loading link.
3, press product drawing regulation, to hydraulic servo fatigue system input technology parameter, then frequency, amplitude start test.
4, record test figure.
The utility model beneficial effect: the stationary installation that provides a kind of steering knuckle that is connected and fixed to be connected with the start cylinder of hydraulic servo fatigue system, realize entrucking front steering joint durable test, eliminate the impact of other parts on test findings, make test figure more accurate.The cost of development of saving steering knuckle, has shortened the construction cycle, and this is simple in structure, and functional reliability is high, with low cost.Utilize the utility model device to verify the analytic method of steering knuckle, for the innovative design of steering knuckle provides reliable foundation.
accompanying drawing explanation
Fig. 1 is test steering knuckle durability test apparatus side force direction schematic diagram of the present utility model.
Fig. 2 is test steering knuckle durability test apparatus longitudinal force of the present utility model and vertical force direction schematic diagram.
In figure: 1-fastening nut, 2-steering knuckle to be measured, 3-loading floor, 4-side direction loading seat, 5-copper sheathing ring, 6-load link.
Embodiment
Below in conjunction with accompanying drawing 1-2, pass through specific embodiment, to the principle of work of position and interconnected relationship, various piece between the structure of the involved all parts of technique scheme of the present utility model, various piece and method of operating etc., further detailed explanation, with help those skilled in the art to utility model of the present utility model conceive, technical scheme has more complete, deeply and understanding accurately.
embodiment 1
