Abstract
The utility model discloses a noise detection device for an automobile rear axle main reducer assembly, comprising shock sensors and a control cabinet which performs processing, displaying and storing to shock information through an operational software, and also comprising a vertical power source connected to an input shaft of a rear axle main reducer and an axle housing arranging the rear axle main reducer on a horizontal base, wherein the shock sensors comprise a horizontal shock sensor and a vertical shock sensor which are arranged on the rear axle main reducer. The noise detection device of the utility model can detect shock values of the rear axle main reducer in different speed ranges of the whole automobile, and can distinguish quality defect kinds and component areas of the rear axle main reducer, thereby eliminating influence to a determining result caused by personal factors.
Description
(1) technical field:
The utility model relates to the auto parts and components measurement mechanism, is a kind of automobile axle main gearbox assembly noise detection device specifically.
(2) background technology:
The abnormal sound of China's automobile axle main gearbox assembly detection at present all is to adopt artificial experience subjective judgements such as ear is listened, feel, and the diagnosis of abnormal sound reason also is the experience with the operator.In the deterministic process, often because of different operating person experience difference causes the product quality difference of dispatching from the factory, or because of same operator's mood, the different product quality differences of dispatching from the factory that cause with energy of muscle power.
(3) utility model content:
The purpose of this utility model has provided the artificial judgement of a kind of elimination, adopts the automobile axle main gearbox assembly noise detection device of quantizating index.
Can realize the automobile axle main gearbox assembly noise detection device of above-mentioned purpose, comprise shock sensor and the switch board of vibration information being handled, being shown and stores by function software, different is also comprises the power source that connects the rear-end gear reduction input shaft and rear-end gear reduction is installed on clamp body on the base, and described shock sensor is located on the rear-end gear reduction.The drive power source rear-end gear reduction rotates simulation car load running status, shock sensor is passed to switch board with the vibration information of rear-end gear reduction, the shocking waveshape figure and the shock value that provide by switch board quantize judgement to product quality, and to causing vibrations and abnormal noise to carry out tentative diagnosis.
Described shock sensor adopts horizontal vibrating sensor and vertical vibration sensor usually, the vibrations of main detection level and vertical both direction.
Described horizontal vibrating sensor is near the power source setting, and described vertical vibration sensor is near the clamp body setting.
For eliminating the vibrations that site error causes, described power output shaft connects the rear-end gear reduction input shaft by flexible joint.
Be the shock value of detection rear-end gear reduction, but described power source possesses different rotating speeds or stepless speed regulation in the car load friction speed.
Be the confined state of simulation rear axle assy, described clamp body is the axle housing bag that assembles with rear-end gear reduction.
Advantage of the present utility model:
The utility model automobile axle main gearbox assembly noise detection device is provided with shock sensor and switch board, can detect the shock value of rear-end gear reduction in car load friction speed section, can distinguish rear-end gear reduction mass defect kind and component area, eliminate the influence of human factor judged result.
