Description

Technical Field

[0001] This utility model relates to the field of clutch testing technology, specifically to a test bench for a hybrid power clutch. Background Technology

[0002] The primary function of a hybrid power clutch test bench is to simulate clutch operation under various conditions, including start-up, acceleration, and deceleration. These tests allow for the evaluation of key indicators such as clutch durability, response speed, and thermal management performance. Furthermore, the test bench can perform noise analysis and data acquisition to ensure the clutch's stability and reliability under diverse conditions. NVH testing refers to the testing of noise, vibration, and acoustic roughness, primarily used to evaluate the noise and vibration levels of a vehicle under different driving conditions to ensure that the vehicle meets comfort and quietness requirements.

[0003] The existing technology has the following shortcomings: When testing hybrid clutches, the existing test bench cannot be easily adjusted according to the size of the clutch, which makes it impossible for the testing components to stably perform NVH testing on different positions of the housing of clutches of different sizes. This makes the test results prone to deviation, which will affect the accuracy of the test results and thus affect the testing efficiency of the clutch. Utility Model Content

[0004] The purpose of this invention is to provide a test bench for a hybrid power clutch. The distance between the forward sensor probe and the lateral sensor probe and the clutch can be adjusted by a first adjusting screw and two second adjusting screws. In turn, the forward sensor probe and the two lateral sensor probes can be used to perform NVH testing on the clutch, making the test results more accurate and improving the clutch testing efficiency, thereby solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a test bench for a hybrid power clutch, including a fixing mechanism, and further comprising:

[0006] The testing mechanism is located on the outer side of one end of the top of the fixed mechanism and is used to perform NVH testing on the clutch.

[0026] This utility model provides, for example Figure 1 The test bench for a hybrid power clutch shown includes a fixing mechanism 1, and further includes:

[0027] Testing mechanism 2 is located on the outer side of one end of the top of the fixed mechanism 1 and is used to perform NVH testing on the clutch;

[0028] The drive mechanism 3 is located at the other end of the top of the fixed mechanism 1 and is used to drive the clutch to be tested to rotate.

[0029] To facilitate NVH testing at different locations of the clutch, such as Figure 1-3 As shown, the detection mechanism 2 includes a first adjusting screw 201 and two second adjusting screws 204. The first adjusting screw 201 is disposed on the top inner wall of one end of the fixed mechanism 1. A movable plate 202 is threaded onto the outer side of the first adjusting screw 201. A forward sensor probe 203 is fixedly installed on the bottom inner wall of the movable plate 202. The forward sensor probe 203 is disposed on the outer wall of one end of the clutch. The two second adjusting screws 204 are respectively disposed on the inner walls of the two sides of one end of the fixed mechanism 1. An adjusting plate 205 is threaded onto the outer wall of each of the two second adjusting screws 204. A lateral sensor probe 206 is fixedly installed on the inner wall of one end of each of the two adjusting plates 205. The two lateral sensor probes 206 are enclosed on the outer walls of the two sides of the clutch. The rotation of the first adjusting screw 201 and the two second adjusting screws 204 can adjust the position of the forward sensor probe 203 and the two lateral sensor probes 206, so that they can be easily adjusted according to the size of the clutch, thereby facilitating NVH detection at different positions of the clutch.

[0030] To facilitate the rotation of the clutch, such as Figure 1-4 As shown, the fixing mechanism 1 includes a fixing base plate 101, a fixing plate 103 is fixedly installed at the other end of the top of the fixing base plate 101, a fixing shaft 104 is rotatably installed on the inner wall of the fixing plate 103, and a connecting groove 105 is opened on the inner wall of one end of the fixing shaft 104. The driving mechanism 3 includes a mounting plate 304, which is located at the top of the fixing base plate 101 away from the fixing plate 103. A driving shaft 305 is rotatably installed on the inner wall of the mounting plate 304. A second motor 306 is provided at one end of the driving shaft 305, and a plug rod 307 that is movably connected to the connecting groove 105 is fixedly installed on the outer wall of the other end of the driving shaft 305. The plug rod 307 is connected to the connecting groove 105 so that the rotation of the driving shaft 305 can drive the fixing shaft 104 to rotate, thereby conveniently driving the clutch to rotate.

[0031] To facilitate the adjustment of the connection between the plug rod 307 and the connecting slot 105, such as Figure 2-4As shown, a movable groove 102 is provided on the inner wall of one end of the top of the fixed base plate 101. An adjusting screw 301 is rotatably installed on the inner wall of the movable groove 102. A first motor 302 is provided at one end of the adjusting screw 301. A movable seat 303 is threaded onto the outer side of the adjusting screw 301. The top of the movable seat 303 is fixedly connected to the bottom of the mounting plate 304. The movable groove 102 can limit the movement of the movable seat 303, so that the mounting plate 304 remains stable during movement, thereby allowing the plug rod 307 to stably connect or disconnect from the connecting groove 105.

[0032] To ensure that the forward sensor probe 203 and the lateral sensor probe 206 remain stable during adjustment, such as Figure 2-3 As shown, mounting slots 106 are provided on the top and inner walls of both sides of the fixed plate 103. The inner wall of the top mounting slot 106 is rotatably connected to the first adjusting screw 201 and movably connected to the outer wall of the movable plate 202. The two mounting slots 106 on both sides are rotatably connected to the two second adjusting screws 204 respectively, and the inner walls of the two mounting slots 106 are movably connected to the outer walls of the two adjusting plates 205 respectively. The top mounting slot 106 can limit the movement of the movable plate 202, and the two mounting slots 106 on both sides can limit the movement of the two adjusting plates 205, thereby keeping the forward sensor probe 203 and the lateral sensor probe 206 stable during the adjustment process.

[0033] During clutch testing, the clutch is fitted onto the outside of the fixed shaft 104. Rotating the first adjusting screw 201 moves the movable plate 202 along the inner wall of the top mounting groove 106, adjusting the height of the forward sensor probe 203 to its forward position on the clutch housing. Simultaneously, rotating the two second adjusting screws 204 moves the two adjusting plates 205 along the inner walls of the side mounting grooves 106, adjusting the positions of the two side sensor probes 206 to their respective positions on the outside of the clutch. Then, the first motor 302 rotates the adjusting screw 301, causing the movable seat 303 to move along the inner wall of the movable groove 102, which in turn moves the mounting plate 304, allowing the insertion rod 307 to be inserted. The clutch is connected to the connecting groove 105 on the inner wall of one end of the fixed shaft 104. The drive shaft 305 can limit the clutch, and the second motor 306 works to make the drive shaft 305 rotate. Through the connection between the plug rod 307 and the connecting groove 105, the fixed shaft 104 rotates accordingly, which in turn drives the clutch to rotate. This allows the forward sensor probe 203 and the two side sensor probes 206 to perform NVH detection on different positions of the clutch. This makes it possible for the test bench to conveniently perform NVH detection on different positions of clutches of different sizes, which can improve the accuracy of clutch detection results and improve the efficiency of clutch detection. This embodiment specifically solves the problem in the prior art that it is not convenient to perform NVH detection on different positions of clutches of different sizes, which affects the accuracy of detection results and the efficiency of detection.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
