Description
Technical field
The utility model relates to the assembling of a kind of steering box and experimental technique field, is specifically a kind of simple and easy accurate steering box noise test stand.
Background technology
Current each whole-car firm more and more pays close attention to for vehicle NVH performance, and the NVH accordingly for steering box requires also more and more higher.What therefore the noise pre-detection of steering box when development just became is particularly important.The test of stand noise can when not having real vehicle, and the commutation states of simulation car load, plays a multiplier effect.It is very important for designing a kind of simple and easy accurate steering box noise test stand for this reason.
Summary of the invention
The difficult problem that the utility model breaches prior art devises a kind of simple and easy accurate steering box noise test stand.
In order to achieve the above object, the utility model devises a kind of noise test stand of steering box, comprise base, connecting link, front connecting tooling, input shaft, coupling sleeve, annular holder, it is characterized in that: one end of connecting link is arranged with base one, rubber damping block one, front connecting tooling, input shaft, the central authorities of connecting link are arranged with annular holder one, coupling sleeve, annular holder two, and the other end of coupling shaft is arranged with rear connecting tooling, rubber damping block two, base two; The side of described rubber damping block one is connected with one end of front connecting tooling, the other end of front connecting tooling is connected with the side of input shaft, the opposite side of input shaft is connected with the side of annular holder one, the opposite side of annular holder one is connected with one end of coupling sleeve, the other end of coupling sleeve is connected with the side of annular holder two, the opposite side of annular holder two is connected with one end of rear connecting tooling, the other end of rear connecting tooling is connected with the side of rubber damping block two, and the opposite side of rubber damping block two is connected with base two.
The damping stiffness of described rubber damping block one and rubber damping block two is 50 ~ 200N/mm.
The front connecting tooling of described rubber damping block one is provided with bulb one and bulb two.
The rear connecting tooling of described rubber damping block two is provided with bulb three and bulb four.
The utility model compared with prior art, can simulate the commutation work state of steering box in car load, effectively saves and analyzes and the supervision time, improve noise analysis efficiency; Any noise can not be produced in test process.When needs simulation different loads, can also the rubber damping block of dismounting and change different-stiffness, product versatility and simulation strong; Structure is simple, can simulate the car load steering box duty of all steering boxs, improves stand noise analysis ability.
