[0002] The dual-mass flywheel is a core component in automotive powertrain systems used to optimize vibration and noise control. It breaks away from the traditional single-mass flywheel design, splitting the flywheel function into two independent mass bodies connected by a flexible mechanism. The primary mass body is directly connected to the engine crankshaft, and its main function is to store the kinetic energy of the engine during operation and maintain the stability of the crankshaft speed. The secondary mass body is connected to the transmission input shaft through a clutch and is responsible for transmitting power to the transmission. The two mass bodies are not rigidly fixed, but are flexibly connected by shock-absorbing components such as springs and dampers.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1-4This utility model provides a strength testing mechanism for machining a dual-mass flywheel in automobiles, including a test chamber 1. A placement platform 2 is rotatably connected to the top of the test chamber 1. An infrared rangefinder 3 is fixedly connected to the outer side of the placement platform 2, located at the top of the test chamber 1. During testing, because the distance between the edge and center of the circle is the same, the data changes when the flywheel deforms, thus effectively testing the flywheel's resilience and facilitating strength testing. A support frame 4 is installed at the front end of the test chamber 1. A fixing component is provided in the middle of the placement platform 2, including a limiting tube 201 fixedly connected to the middle of the placement platform 2. A support is slidably connected inside the limiting tube 201. The support block 202 has a support pad 203 fixedly connected to one end, and a limit slider 204 fixedly connected to the end of the support block 202 away from the support pad 203. A trapezoidal block 205 is slidably connected between the limit sliders 204, and a buffer spring 206 is fixedly connected to the top of the trapezoidal block 205. A housing 207 is rotatably connected to the bottom of the placement platform 2. An electric push rod 208 is fixedly installed inside the housing 207. The telescopic end of the electric push rod 208 passes through the limit tube 201 and is rotatably connected to the trapezoidal block 205. The end of the support block 202 away from the support pad 203 is inclined and fits against the side surface of the trapezoidal block 205. The limit slider 204 is slidably connected to the inner wall of the side surface of the trapezoidal block 205.

[0018] When a strength test is required on a dual-mass flywheel of an automobile, the flywheel is first placed on the placement platform 2. The electric push rod 208 inside the housing 207 is activated. The telescopic end of the electric push rod 208 pushes the trapezoidal block 205 up and down along the inside of the limiting tube 201. Since the end of the support block 202 away from the support pad 203 is inclined and fits against the side surface of the trapezoidal block 205, the trapezoidal block 205 will generate a radial thrust on the support block 202 when it rises, causing the support block 202 to slide along the inside of the limiting tube 201 until the support pad 203 is in close contact with the inner wall or outer side of the flywheel, thus fixing the flywheel. The fixing component of this utility model, through the cooperation of the electric push rod 208 and the trapezoidal block 205 to drive the support block 202 to move, can adjust the fixing range according to the dual-mass flywheel of different sizes. It has strong adaptability and is easy to operate, improving the testing efficiency of the staff. The support pad 203 can increase the friction with the flywheel, prevent the flywheel from loosening during the test, and reduce the wear on the surface of the flywheel.

[0019] Specifically, such as Figure 1 As shown, a limiting groove 401 is provided at the front end of the test box 1. An electric slide rail 402 is fixedly installed inside the limiting groove 401. The support frame 4 is slidably connected to the outside of the electric slide rail 402. Hydraulic cylinders 403 are symmetrically distributed on the left and right sides and fixedly installed at the bottom of the support frame 4. The telescopic end of the hydraulic cylinder 403 is fixedly connected to the support base 404, and a test ball is placed inside the support base 404.

[0020] According to the height requirements of the test, the electric slide rail 402 inside the front limiting slide groove 401 of the test chamber 1 is activated. The electric slide rail 402 drives the support frame 4, which is slidably connected on the outside, to rise and fall vertically along the limiting slide groove 401 until the hydraulic cylinder 403 at the bottom of the support frame 4 is aligned with the flywheel test area. Then, the hydraulic cylinder 403 is activated. The telescopic end of the hydraulic cylinder 403 pulls the support base 404 apart. After that, the test ball placed inside the support base 404 will fall onto the surface of the flywheel to conduct a collision test.

[0021] Specifically, such as Figure 2 and Figure 3 As shown, a buffer pad 5 is fixedly connected to the top of the placement platform 2. The installation of the buffer pad 5 effectively supports the flywheel, improving the safety and stability of the flywheel placement. A gear ring 6 is fixedly connected to the side surface of the placement platform 2. A gear 7 is meshed with the outer side of the gear ring 6. A rotary motor 8 is fixedly connected to the bottom of the gear 7. The rotary motor 8 is fixedly installed on the inner wall of the test chamber 1. During the test, the operator can start the rotary motor 8, causing the transmission end of the rotary motor 8 to drive the gear 7 and the gear ring 6 to rotate in sequence, thereby driving the placement platform 2 and the flywheel fixedly installed on its top to rotate. During the rotation, the flywheel is detected in real time by the infrared rangefinder 3, thereby testing the strength of the flywheel.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, the top of the buffer spring 206 is fixedly connected to the inner top wall of the limiting tube 201, and the housing 207 is fixedly connected to the test box 1. The installation of the buffer spring 206 can not only buffer the rise of the trapezoidal block 205, but also push the trapezoidal block 205 when it falls.

[0023] Working principle and usage process of this utility model: When staff conduct a strength test on a dual-mass flywheel of a car, they first place the flywheel to be tested on the buffer pad 5 on top of the placement platform 2. Then, the electric push rod 208 inside the housing 207 is activated. The telescopic end of the electric push rod 208 pushes the trapezoidal block 205 up and down along the inside of the limiting tube 201. Because the end of the support block 202 away from the support pad 203 is inclined and fits against the side surface of the trapezoidal block 205, the trapezoidal block 205 will generate a radial thrust on the support block 202 when it rises, causing the support block 202 to slide along the inside of the limiting tube 201 until the support pad 203 is in close contact with the inner wall or outer side of the flywheel to fix the flywheel. After the flywheel is fixed, according to the test height requirements, the electric slide rail 402 inside the front limit slide groove 401 of the test box 1 is activated. The electric slide rail 402 drives the support frame 4, which is slidably connected on the outside, to rise and fall vertically along the limit slide groove 401 until the support frame 4 rises to the appropriate height. Next, the hydraulic cylinder 403 is activated, and its telescopic end pulls the support base 404 apart. The test ball inside the support base 404 falls onto the flywheel surface for a collision test. After the test, the test ball is removed. The operator can then activate the rotary motor 8 fixed to the inner wall of the test chamber 1. The transmission end of the rotary motor 8 drives the gear 7 to rotate, which in turn drives the placement platform 2 and the top flywheel to rotate. At the same time, the infrared rangefinder 3 located at the horizontal top of the test chamber 1 and outside the placement platform 2 detects the flywheel in real time. Utilizing the characteristic that the distance between the circular edge and the center point is the same, if the flywheel deforms, the detection data will change, thereby effectively testing the flywheel's durability and strength, and completing the entire testing process.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
