[0002] The flywheel housing acts as a bridge between the engine and the gearbox, securely connecting the two and ensuring that the power generated by the engine can be smoothly transmitted to the gearbox. Rotating components such as the flywheel are isolated from the outside world to prevent people or other objects from coming into contact with the high-speed rotating parts and causing danger. It also prevents foreign objects from entering the transmission mechanism between the engine and the gearbox and affecting power transmission.

[0003] Traditional flywheel housing assembly installation methods have many shortcomings. When vehicles or equipment require maintenance, traditional flywheel housing connection methods may require a significant amount of time to remove numerous bolts and screws to access the two connected flywheel housings. At the same time, it is also very inconvenient to inspect and maintain the internal condition of the flywheel housing, lacking an effective observation and convenient maintenance structure, making it difficult to quickly detect and resolve internal flywheel housing problems, thus affecting the normal operation of the engine.

[0029] Example 1

[0030] Please see Figures 1-6 This utility model provides a technical solution: a flywheel housing assembly for an automobile engine, including a quick-release assembly 1. The quick-release assembly 1 includes a limiting rod 101. A square groove 105 is formed on the inner wall of the limiting rod 101.

A pull rod 7 is fixedly installed on the outer wall of the cover plate 8. Here, the quick-release assembly 1 is connected to the connecting plate 2, and the connecting plate 2 fixes the flywheel housing body 3. This connection method makes the entire assembly structure compact and securely installed. The sound-absorbing cotton 4 installed on the inner wall of the flywheel housing body 3 effectively absorbs the noise generated during engine operation, reducing the impact of noise on the vehicle interior and the outside environment. The observation piece 5 and the connecting assembly 6 allow operators to easily view the inside of the flywheel housing through the observation piece 5, while the connecting assembly 6 conveniently connects the cover plate 8 and the pull rod 7, simplifying operation when opening or closing the observation port and improving the maintainability and observability of the equipment.

[0032] The outer wall of the limiting rod 101 is slidably connected to the inner wall of the connecting plate 2. The outer wall of the rotating shaft 102 passes through the outer wall of the limiting rod 101 and is fixedly installed on the inner wall of the gear 106. One side of the outer wall of the elastic element 103 is fixedly installed on the outer wall of the limiting plate 104, and the other side of the outer wall of the elastic element 103 is fixedly installed on the inner wall of the square groove 105. Here, the outer wall of the limiting rod 101 is slidably connected to the inner wall of the connecting plate 2, ensuring that the limiting rod 101 can move smoothly within the connecting plate 2, facilitating fine-tuning of its position during installation. The rotating shaft 102 passes through the limiting rod 101 and is fixedly installed on the gear 106, enabling effective force transmission. When the gear 106 is operated, the rotating shaft 102 can be rotated, thereby changing the position of the limiting plate 104. The two ends of the elastic element 103 are fixed to the inner wall of the limiting plate 104 and the square groove 105 respectively, ensuring that the limiting plate 104 can automatically reset after rotation, maintain good limiting function, and provide a guarantee for the stable operation of the entire quick-release assembly 1.

[0033] The bottom of the limiting plate 104 contacts the outer wall of the connecting plate 2. The outer wall of the fixing member 108 is slidably connected to the inner wall of the limiting rod 101. The outer wall of the snap-fit ​​member 112 is snapped into the inner wall of the rectangular groove 111. There are two sets of rotating shaft 102, elastic member 103, limiting plate 104, rectangular groove 105, gear 106, and toothed block 107. The two sets of rotating shaft 102, elastic member 103, limiting plate 104, rectangular groove 105, gear 106, and toothed block 107 are symmetrically arranged on the outer wall of the limiting rod 101 with the fixing member 108 as the axis. Here, the bottom of the limiting plate 104 contacts the outer wall of the connecting plate 2, which can further limit the position of the limiting rod 101 and prevent it from moving excessively. The outer wall of the fixing member 108 is slidably connected to the inner wall of the limiting rod 101, ensuring the smooth movement of the fixing member 108 within the limiting rod 101. The snap-fit ​​design of the snap-fit ​​component 112 and the rectangular groove 111 ensures that the fixing component 108 can be firmly fixed in a specific position, preventing loosening. The two sets of symmetrically arranged rotating shafts 102, elastic element 103, limiting plate 104 and other structures enhance the stability and reliability of the limiting function, enabling the entire quick-release assembly 1 to work stably under different working conditions.

[0034] The connecting assembly 6 includes a long rod 601, a pull plate 602 fixedly mounted on the outer wall of the long rod 601, a ring 603 slidably connected to the outer wall of the long rod 601 away from the pull plate 602, an elastic element 604 sleeved on the outer wall of the long rod 601, a round rod 605 fixedly mounted on the inner wall of the long rod 601, an elastic element 606 fixedly mounted on the outer wall of the round rod 605, and a steel ball 607 fixedly mounted on the outer wall of the elastic element 606 away from the round rod 605. Here, the long rod 601, pull plate 602, ring 603, elastic element 604, round rod 605, elastic element 606, and steel ball 607 in the connecting assembly 6 cooperate to achieve a unique connecting function. The long rod 601 can slide within a circular groove on the outer wall of the observation piece 5, facilitating adjustment of the connection position. The pull plate 602 facilitates the operator's application of force to pull the long rod 601. The ring 603 fits and is fixed to the circular groove, providing a stable track for the sliding of the long rod 601. The elastic element 604 provides elastic support, allowing the long rod 601 to remain in a suitable position when no external force is applied. The combination of the round rod 605, the elastic element 606, and the steel ball 607 allows for convenient engagement and disengagement between the long rod 601 and the pull rod 7, facilitating the opening and closing of the observation port cover 8.

[0035] The outer wall of the long rod 601 is slidably connected to the inner wall of the circular groove on the outer wall of the observation piece 5. The outer diameter of the ring 603 matches the inner diameter of the circular groove, and the outer wall of the ring 603 is fixedly installed on the inner wall of the circular groove. This slidable connection between the outer wall of the long rod 601 and the inner wall of the circular groove on the outer wall of the observation piece 5 ensures the accuracy and stability of the long rod 601's movement. The matching and fixed installation of the outer diameter of the ring 603 with the inner diameter of the circular groove ensures the firmness of the connecting assembly 6 on the observation piece 5, preventing shaking or detachment during use, making the entire connection structure more reliable, and providing a guarantee for the normal use of the observation port.

[0036] One outer wall of the elastic element 604 is fixedly installed to the outer wall of the ring 603, and the other outer wall of the elastic element 604 is fixedly installed to the inner wall of the circular groove. The outer wall of the long rod 601 away from the pull plate 602 contacts the inner wall of the cover plate 8, and the outer wall of the steel ball 607 is engaged with the inner wall of the cover plate 8. Here, the two ends of the elastic element 604 are fixedly installed to the ring 603 and the inner wall of the circular groove, respectively, providing an outward elastic force for the long rod 601, so that the long rod 601 can be held in a specific position when not subjected to external force, which facilitates the installation of the cover plate 8. The outer wall of the long rod 601 away from the pull plate 602 contacts the inner wall of the cover plate 8, which can guide the cover plate 8 into accurate position during installation. The outer wall of the steel ball 607 is engaged with the inner wall of the cover plate 8, which further enhances the fixing effect of the cover plate 8 after installation, prevents it from being opened accidentally during equipment operation, ensures the sealing and safety of the inside of the observation piece 5, and also facilitates the disassembly of the cover plate 8. It can be achieved by applying a certain external force to overcome the elastic force of the elastic element 606.

[0037] There are two sets of connecting plates 2 and two sets of flywheel housing bodies 3. The two sets of connecting plates 2 are fixed to the two sets of flywheel housing bodies 3 via quick-release components 1. The sound-absorbing cotton 4 is made of ceramic fiber. The observation piece 5 is fixed to the cover plate 8 via connecting components 6. Here, the two sets of connecting plates 2 are fixed to the two sets of flywheel housing bodies 3 via quick-release components 1. This design enhances the structural strength and stability of the entire flywheel housing assembly, and can better adapt to the vibration and impact generated during engine operation. The sound-absorbing cotton 4 is made of ceramic fiber. Ceramic fiber has good sound absorption and high temperature resistance, and can effectively absorb the noise generated by the engine in high-temperature environments, while ensuring its own performance stability and extending the service life of the sound-absorbing cotton 4. The observation piece 5 is fixed to the cover plate 8 via connecting components 6, which facilitates the observation and maintenance of the inside of the flywheel housing, ensures the normal operation of the equipment and timely maintenance, and improves the reliability and safety of the equipment.

[0038] Working principle: When the operator needs to observe the internal condition of the flywheel housing, pulling the pull plate 602 causes the long rod 601 to disengage from the inner wall of the cover plate 8. At this time, the two sets of steel balls 607 are forced to push down the elastic element 606, allowing the two sets of steel balls 607 to enter the inner wall of the long rod 601. Continuing to pull the pull plate 602 causes the long rod 601 to slide on the inner wall of the ring 603, compressing the elastic element 604 on the outer wall of the ring 603. This causes the long rod 601 to slide out of the inner wall of the cover plate 8. At this time, by pulling the pull rod 7, the cover plate 8 slides out from the inner wall of the observation piece 5. The cover plate 8 can be removed, and the maintenance personnel can observe the inner wall of the flywheel housing body 3 through the observation piece 5. When there are no abnormalities in the inner cavity of the flywheel housing body 3, the cover plate 8 is put back into the observation piece. The inner wall of the cover plate 8 is pressed against the long rod 601, causing the long rod 601 to slide and retract on the inner wall of the ring 603. When the cover plate 8 enters the inner wall of the observation piece 5, the elastic element 604 is also compressed. When the rectangular groove 111 descends to correspond with the pull plate 602, the pull plate 602 loses its force, and the long rod 601 can enter the inner wall of the cover plate 8. When the long rod 601 enters the inner wall of the cover plate 8, the circular groove opened on the inner wall of the cover plate 8 corresponds to the outer wall of the steel ball 607, allowing the steel ball 607 to enter the circular groove. At this time, the steel ball 607 presses against the elastic element 606 to fix it to the inner wall of the cover plate 8. When there is a problem with the inner cavity of the flywheel housing body 3 and it needs to be repaired, since the outer wall of the limit rod 101 is slidably connected to the inner wall of the connecting plate 2, the limit rod 101 needs to be pulled out from the inner wall of the connecting plate 2 along the sliding direction.During this process, because the bottom of the limiting plate 104 contacts the outer wall of the connecting plate 2, by pulling the fixing member 108 out from the inner wall of the limiting rod 101, the fixing member 108 drives the snap-fit ​​member 112 to exit the inner wall of the rectangular groove 111. At this time, the fixing member 108 slides on the inner wall of the limiting rod 101, causing the fixing member 108 to drive the tooth block 107 to mesh with the gear 106. As a result, the gear 106 drives the rotating shaft 102 to rotate, and the rotating shaft 102 drives the elastic member 103 to rotate the limiting plate 104. At this time, the limiting plate 104 enters the inner wall of the limiting rod 101, so the limiting rod 101 can be pulled out from the inner wall of the connecting plate 2. At this time, the two sets of flywheel housing bodies 3 can be separated, and maintenance personnel can repair the inner wall of the flywheel housing body 3. After the repair is completed, the limiting rod 101 is inserted. The inner wall of the connecting plate 2 is then connected, and the fixing plate 110 is screwed onto the threaded rod 109 along the thread direction to fix the fixing plate 110 to the threaded rod 109. At this time, the outer wall of the fixing member 108 is inserted into the inner wall of the limiting rod 101, and the outer wall of the snap-fit ​​member 112 is snapped into the inner wall of the rectangular groove 111 opened in the inner wall of the limiting rod 101. Thus, when the fixing member 108 slides, it drives the tooth block 107 to rotate the gear 106. At this time, the gear 106 drives the rotating shaft 102 to unfold the limiting plate 104, so that the limiting plate 104 can be snapped into the outer wall of the connecting plate 2 to prevent it from falling off. At this time, the two sets of flywheel housing bodies 3 are fixed to the snap-fit ​​of the connecting plate 2 through the quick-release assembly 1. Since the sound-absorbing cotton 4 on the inner wall of the flywheel housing body 3 continuously absorbs the noise generated by the engine operation, the noise impact on the vehicle interior and the outside world is reduced.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
