Technical Field
The utility model belongs to the technical field of the automotive engineering technique and specifically relates to it is steering gear noise detection device to relate to.
Background
Automobile noise has gradually attracted attention and attention as an important index for evaluating automobile comfort. At present, the corresponding noise evaluation is carried out on the automobile before the automobile is put into the market formally. The steering gear is used as a key component in an automobile steering system, and the comfort of passengers can be directly influenced, so that the steering gear can correspondingly detect the noise condition before leaving a factory. In the noise detection process of the steering gear, a corresponding load mechanism is required to provide certain damping for the steering gear so as to simulate the stress condition of the steering gear in the whole vehicle environment. The noise result obtained by the method is closer to the performance of the whole vehicle under the actual condition.
