An embodiment of the utility model provides a hybrid clutch testing arrangement, its test that is used for hybrid clutch performance.

As shown in fig. 1, the hybrid clutch test apparatus of the present embodiment includes: a power input mechanism 41 and a load mechanism 42.

The power input mechanism 41 is used for providing power to the hybrid clutch so as to simulate the working condition of the hybrid clutch under different conditions. The power input mechanism 41 includes: an input connector 411, an input motor 412 and a linear module 413.

The input motor 412 is a servo motor, and may be in transmission connection with the input connector 411 through a reducer or the like, and the input connector 411 may be further connected with an input end of the hybrid clutch. In order to drive the input connector 411 to cooperate with the hybrid clutch, the linear module 413 drives the whole of the input connector 411 and the input motor 412 to reciprocate relative to the loading mechanism 42. In this way, when the input connector 411 is driven by the linear module 413 to work close to the hybrid clutch, the input connector 411 can be inserted into the input end of the hybrid clutch.

In one embodiment, the linear module 413 includes: a screw 4131, a rotary motor 4132, and a linear guide 4133. At this time, the output end of the rotary motor 4132 is connected to one end of the screw 4131, the screw 4131 is further connected to the bottom of the power input mechanism 41 in a transmission manner, and the linear guide 4133 is disposed below the power input mechanism 41. Therefore, when the rotary motor 4132 is operated, the screw 4131 drives the power input mechanism 41 to move along the linear guide 4133.

The load mechanism 42 is used for transmitting the hybrid clutch transmitted by the epicyclic device 30, and can simulate a load to work under the driving of the output power of the hybrid clutch. The loading mechanism 42 is located on one side of the power input mechanism 41, and is disposed coaxially with the power input mechanism 41 in a horizontal state.

The load mechanism 42 includes: a fixing clamp 421, an output motor 422 and a turnover module 423.

The fixing clamp 421 is arranged at the input end of the output motor 422, and is provided with a cavity suitable for assembling the hybrid clutch and the upper tool clamp 10, and the periphery of the cavity is also provided with a hydraulic clamping jaw 4211 capable of pivoting and pressing the tool clamp 10. Thus, after the hybrid clutch to be tested is placed in the cavity, the hydraulic clamping jaw 4211 can pivot to the upper side of the hybrid clutch and press down to abut against the tooling fixture 10 to fix the hybrid clutch. At the same time, the output of the hybrid clutch, which is assembled in place, also mates with the input of the output motor 422.

In this embodiment, the testing device 40 is horizontally disposed, so that the turning module 423 can drive the whole of the fixing clamp 421 and the output motor 422 to be switched between a vertical state and a horizontal state for facilitating vertical loading of the hybrid clutch.

During the feeding of the hybrid clutch, the overturning module 423 drives the fixing clamp 421 and the output motor 422 to pivot to a vertical state, so that the cavity of the fixing clamp 421 is arranged upward, the hybrid clutch is placed in the fixing clamp 421 by the transferring device 30, and the hybrid clutch is in a horizontal state at the moment.

When the hybrid clutch is assembled in place, the flipping module 423 drives the fixing clamp 421 and the output motor 422 to rotate to a vertical state, at this time, the hybrid clutch is in the vertical state, and the input connector 411 of the power input mechanism 41 can be inserted into the input end of the hybrid clutch.

Therefore, since the operating frequency of the input motor 412 can be set according to requirements, the hybrid clutch can operate under set conditions (rotation speed, torque, etc.), and further, by detecting the operating conditions of the hybrid clutch and the load mechanism 42, the test of the operating conditions of the hybrid clutch under different operating conditions can be realized, so as to meet multiple test requirements of the hybrid clutch.

In one embodiment, the flip module 423 includes: and turnover cylinders arranged at two sides of the whole body of the fixing clamp 421 and the output motor 422. The upset cylinder of arbitrary side keeps the slope setting, and its one end is connected with the whole transmission of mounting fixture 421 and output motor 422, and the base fixed connection at the whole place of the other end and mounting fixture 421 and output motor 422. Therefore, when the turnover cylinders on the two sides work, the fixing clamp 421 and the output motor 422 can be driven to perform pivoting motion. Accordingly, the whole of the fixing clamp 421 and the output motor 422 is pivotally provided on the base on which it is located.

In addition, in order to implement the noise test when the hybrid clutch is operated, the testing device 40 further includes a noise testing mechanism 43, and the noise testing mechanism 43 is integrated on the back surface of the gantry 33.

At this time, at least one acceleration sensor 431 collects axial vibration data of the clutch, and at least two acceleration sensors 432 collect vibration data of the clutch in two radial directions. Therefore, at least one axial vibration data and two radial vibration data can be respectively measured, and whether the working noise of the hybrid clutch meets corresponding requirements or not under different working conditions can be further judged.

The noise test mechanism 43 performs a noise test on the hybrid clutch after the power input mechanism 41 and the load mechanism 42 have completed the test. At this time, the

acceleration sensors

431 and 432 are respectively driven by respective cylinders and are in contact with the detection positions of the corresponding hybrid clutches, so that corresponding sensing data are acquired. The noise condition of the hybrid clutch during working can be judged by further analyzing the acquired sensing data.
