Description

Technical Field

[0001] This utility model relates to the field of release bearing technology, specifically a release bearing noise detection and testing device. Background Technology

[0002] The release bearing, also known as the clutch release bearing, is a key component of the automotive clutch system. Located behind the clutch pressure plate, it separates the clutch disc from the flywheel, enabling clutch engagement and disengagement. The main function of the release bearing is to use pressure to separate the clutch disc from the flywheel when the driver depresses the clutch pedal, thereby interrupting the transmission of power from the engine to the transmission, stopping the vehicle or shifting gears. When the driver releases the clutch pedal, the release bearing reconnects the clutch disc to the flywheel, allowing power to be transmitted again and the vehicle to continue moving. The release bearing typically consists of an external pressure plate and an internal bearing. The pressure plate is subjected to pressure via the clutch pressure plate, which in turn causes the internal release mechanism of the bearing to push the clutch disc away from the flywheel. The design and performance of the release bearing have a significant impact on the operating efficiency and smoothness of the clutch system, and directly affect the shifting quality and driving comfort of the vehicle. Therefore, the release bearing plays an important role in the normal operation of the vehicle, ensuring the normal operation of the clutch system and smooth shifting. It is an indispensable component of the automotive transmission system. During long-term use, the release bearing is affected by its own wear, which may cause noise problems. Noise testing of the release bearing is an important means to ensure the normal operation of the clutch system and to diagnose problems. Therefore, after the release bearing is manufactured, it is often necessary to test its noise factor.

[0003] However, existing methods for testing release bearing noise have the following problems: They often require specialized noise testing equipment to detect noise during operation. However, due to the diverse sizes of release bearings, different mounting components must be selected for different sizes, making the assembly and disassembly process cumbersome. Furthermore, the position of the noise acquisition component directly affects the accuracy of the noise acquisition, and there is a lack of means to flexibly adjust the noise acquisition component based on the release bearing's location. Therefore, a corresponding technical solution needs to be designed to address these problems. Utility Model Content

The inner end of the six sets of return springs 10 is connected to the limiting rod 16. The limiting rod 16 is fixed at the center of the adjusting plate 8. The tapered tube 11 is slidably arranged in the inner cavity 13 and is connected to the pull rod 12 on one side. The pull rod 12 is slidably arranged in the sliding groove 14. The noise detection mechanism includes two sets of adjusting rods 17 arranged symmetrically and a ring 18 fixed to the outer end of the two sets of adjusting rods 17.

The microphones 19 and the noise tester 20 are conventional microphones 19 and noise testers 20 on the market. The noise tester 20 is attached to the back plate 3.

[0020] Further improvements, such as Figure 1 As shown, the sealing cover is composed of four sets of sealing plates 21 spliced ​​together. Each sealing plate 21 consists of two sets of tempered glass arranged symmetrically, with a sound insulation interlayer formed between the two sets of tempered glass to reduce the interference of external environmental noise.

[0021] Further improvements, such as Figure 2As shown, the six sets of locking rods 9 are arranged in a ring. Each locking rod 9 includes a rod body 22 and a ball bearing 23 fixed to the inner end of the rod body 22. The surface of the rod body 22 is machined with several sets of anti-slip serrations 24. The ball bearing 23 contacts the tapered tube 11. The anti-slip serrations 24 on the locking rod 22 abut against the inner cavity of the release bearing, thereby achieving the purpose of limiting and fixing the release bearing.

[0022] Further improvements, such as Figure 3 As shown, the tapered tube 11 has a conical structure and the diameter of the left end is larger than that of the right end. The position of the clamping rod 9 can be adjusted by the displacement of the tapered tube 11.

[0025] In use: When the release bearing needs to be installed and tested, the operator fits the release bearing onto the six sets of clamps 9. Then, the operator pulls the tapered tube 11 by holding the pull rod 12. During the movement of the tapered tube 11, it acts on the clamps 9. The clamps 9 move along the guide groove 15 and make the anti-slip protrusions 24 on the clamps 22 abut against the inner cavity of the release bearing, which can achieve the purpose of limiting and fixing the release bearing. At this time, the limit bolt 26 is inserted into the corresponding positioning hole 27 to achieve the purpose of limiting the pull rod 12 and the tapered tube 11. Then, by adjusting the length of the adjusting rod 17, the position of the ring 18 can be adjusted so that the ring 18 can be moved to the position of the release bearing to be tested. The noise is acquired by the microphone 19. Finally, the sealing cover is pushed inward and sealed with the sealing groove 5 to achieve the purpose of sealing the inside of the sealing cover.
