[0029] The technical scheme in the embodiment of the utility model will be described below in combination with the drawings in the embodiment of the utility model.

[0030] ​​The embodiments of the utility model are used for explaining the utility model only, and are not used for limiting the range of the utility model. In the following paragraphs, the utility model is described more specifically with reference to the drawings by way of example. It should be noted that the drawings are in a very simplified form and all use non-precise proportions, and are only used to facilitate and clearly assist the purpose of explaining the embodiments of the utility model.

[0031] At present, the limit torque device is usually detected by manual detection. However, the detection result of the limit torque device depends on the subjective evaluation of the detection personnel, and the result of the subjective evaluation is often subject to the personal experience and working attitude of the detection personnel, has uncertainty and randomness, and can cause the accuracy of the detection result to be low, and the unqualified product itself can be misdetected as qualified and shipped, so that the qualified rate of the product shipped can be reduced. In order to solve the above problems, the utility model embodiment provides a limit torque device detection device, and the limit torque device detection device mentioned above is described in detail below.

[0032] In the first aspect, with reference to Figures 1 to 3 The limit torque device detection device provided by the utility model embodiment comprises a driving rotation assembly and a detection assembly, the driving rotation assembly is used for detachable connection with a hub 92 in a limit torque device 9 and is used for driving the hub 92 to rotate, the detection assembly comprises a monitoring module and a detection module electrically connected with the monitoring module, the monitoring module is used for monitoring vibration and / or noise generated by the limit torque device 9 in the rotating process and outputting vibration signals and / or noise signals, and the detection module is used for generating a detection result according to the vibration signals and / or noise signals.

[0033] The limit torque device detection device is specifically applied to the detection of the limit torque device in an automobile, and the automobile can be a new energy automobile, for example, a hybrid electric vehicle. The mainstream hybrid power scheme of the hybrid electric vehicle is that the engine is kept in the high-efficiency zone to generate power, supplies the driving motor or the battery storage, and the motor is responsible for the vehicle driving, so as to reduce the energy consumption and emission of the vehicle. The most important difference between the power architecture of the hybrid electric vehicle and the traditional power architecture is that the clutch in the traditional power architecture is cancelled. The engine and the electric drive system in the hybrid electric vehicle are directly connected through a flywheel and a limit torque device with a limit torque effect.

[0034] The limit torque device 9 mainly comprises elastic elements and damping elements, the main function of the elastic elements is to reduce the first end torsional stiffness of the transmission system, so as to reduce the natural frequency of a certain order of the torsional system, change the natural vibration mode of the torsional system, avoid the main excitation of the engine, and the main function of the damping elements is to dissipate the vibration energy of the system. When the torque of the transmission system exceeds the set limit value, the limit torque device 9 protects the transmission system from the problem of shaft breakage through the slip of the friction plate. The limit torque device 9 mainly comprises a driven disc, a pressure plate, a disc spring, a cover plate 91, a hub 92 and the like.

[0035] The connection mode of the driving rotating assembly and the disc hub 92 can be bolt connection, clamping, insertion, etc. When detecting the torsion limiter 9, first, the driving rotating assembly is connected with the disc hub 92, then the disc hub 92 is driven to rotate by the driving rotating assembly, then the vibration and / or noise generated by the torsion limiter 9 is monitored by the monitoring module and the vibration signal and / or noise signal is output, and then the detection module generates a detection result according to the vibration signal and / or noise signal to detect whether the torsion limiter 9 is qualified.

[0036] The detection module can receive the vibration signal and / or noise signal sent by the monitoring module. After the detection module obtains the vibration signal and / or noise signal, the detection module will perform frequency domain analysis on the vibration signal and / or noise signal and obtain a frequency domain analysis result. Then the frequency domain analysis result is compared with the qualified data in the qualified database. If the comparison is passed, a qualified detection result is generated. If the comparison is not passed, an unqualified detection result is generated. For the unqualified torsion limiter, it will be screened out for repair in advance. After repair, it needs to be detected again until it is qualified to avoid the unqualified torsion limiter from flowing out, thereby saving the after-sales maintenance cost caused by the unqualified torsion limiter flowing out. The detection module can be a notebook computer, and the vibration signal and / or noise signal can be analyzed and processed by the corresponding software running on the notebook computer.

[0037] With the increasing demand of users for ride comfort, manufacturers pay more and more attention to the NVH (Noise, Vibration, Harshness) performance of the automobile. During the use of the whole vehicle, the torsion limiter will work frequently with the start of the engine. When manually detected by artificial, if the unqualified torsion limiter with abnormal noise problem is misjudged as qualified and normally leaves the factory and is assembled to the automobile, the NVH performance of the automobile will be affected.

[0038] In the embodiment of the utility model, in the detection process, the monitoring module can monitor the vibration and / or noise generated by the torque limiter 9 and output vibration signal and / or noise signal, the detection module can generate detection result according to vibration signal and / or noise signal to detect whether the torque limiter 9 is qualified, compared with the manual detection mode, the subjective evaluation can be avoided to cause the misjudgment, thereby the accuracy of detection result can be improved, and the qualified rate of torque limiter factory can be improved. In addition, in the detection process, when the monitoring module monitors the noise generated by the torque limiter 9 and outputs noise signal, the detection module can generate detection result according to noise signal to detect whether the torque limiter 9 has abnormal sound problem, the torque limiter 9 with abnormal sound problem can be identified in advance, the torque limiter 9 with abnormal sound problem can be avoided to flow out, thereby the NVH performance of the automobile equipped with the torque limiter 9 can be avoided to be affected. In addition, the torque limiter detection device has simple structure. In addition, the torque limiter detection device can be used for testing different specifications of torque limiters that can be connected with the driving rotating assembly, for example, when the driving rotating assembly is connected with the spline hole in the torque limiter, as long as the spline hole in the torque limiter of different specifications can adapt to the driving rotating assembly, the torque limiter detection device can be used for detection, and the universality is high.
