Description

Technical Field

[0001] This utility model relates to the technical field of disc-type automobile flywheel assemblies, specifically a disc-type automobile flywheel assembly. Background Technology

[0002] The core function of a disc-type car flywheel assembly is to store and release engine energy, while ensuring smooth engine operation and driving the clutch.

[0003] For example, in a stacked-plate automotive flywheel assembly with announcement number "CN212717811U", the front surface of the flywheel body is provided with a fast heat dissipation feature, the rear surface of the flywheel body has a bushing groove corresponding to the bearing sleeve protrusion, and the side surface of the flywheel body has an installation groove. The gear ring and the flywheel are fixedly connected by steel nails, making it convenient and quick to replace the flywheel gear ring. The flywheel body has strong integrity and good rigidity, and the flywheel body is made of stainless steel, which allows for fast heat dissipation. However, in the use of disc-type automotive flywheel assemblies, the gear ring and the flywheel body are connected by "steel nails (fixing metal rods)" passing through the first and second gear ring fixing holes, replacing traditional welding. In this case, the gear ring is installed separately, and the fixing of the steel nails depends on the alignment accuracy of the holes and the shear and vibration resistance of the steel nails themselves. Under long-term exposure to the high-frequency vibration and torque fluctuation environment of the engine, the steel nails are prone to fatigue wear, leading to loosening of the disc-type automotive flywheel assembly and misalignment of the outer wall gear ring of the disc-type automotive flywheel assembly. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of loose fixing of disc-type car flywheel assembly, which causes misalignment of the outer wall gear ring of disc-type car flywheel assembly, and proposes a disc-type car flywheel assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a disc-type automobile flywheel assembly, including a collar and a circular block. The front side of the collar is fixedly connected to the rear end face of the circular block. Grooves are machined on the upper and lower sides of the circular block. An assembly structure is connected to the outer wall of the circular block, and a fixing structure is connected to the inner wall of the collar.

[0006] This feature: The inner wall of the round block is machined with an opening to facilitate the insertion of the car axle, allowing the car axle to form a through connection with the car flywheel assembly.

[0007] Preferably, the assembly structure includes a toothed ring and a first straight plate. The inner wall of the toothed ring is inserted into the outer wall of the circular block. The front side of the toothed ring is fixedly connected to the outer side of the rear end face of a plurality of first straight plates. A square block is fixedly connected to the upper and lower sides of the inner wall of the toothed ring respectively.

[0008] This setting: After the toothed ring is inserted into the outer wall of the circular block, the inner side of the rear end face of the first straight plate will fit against the front face of the circular block, and the toothed ring can be pulled forward by force to detach from the outer wall of the circular block.

[0009] Preferably, the outer wall of the block is inserted into the inner wall of the groove.

[0010] This setting: After the outer wall of the block is inserted into the inner wall of the groove, it restricts the toothed ring and prevents the toothed ring from rotating at an angle on the outer wall of the block.

[0011] Preferably, the inner side of the outer wall of the first straight plate is connected to the front circular opening of the round block by bolts.

[0012] This setting: The bolts fix the first straight plate and the round block, thereby fixing the position of the toothed ring connected to the first straight plate and preventing the toothed ring from detaching from the outer wall of the round block.

[0013] Preferably, the front side of the circular block is fixed with multiple fins.

[0014] This setting: The fins are made of copper, and the heat generated by the heat source will be quickly transferred to every part of the fins through heat conduction, avoiding heat accumulation on the surface of the heat source.

[0015] Preferably, the fixing structure includes a circular plate and a circular rod. The outer wall of the circular plate is fixedly connected to the outer wall of the collar. The left and right sides of the front of the circular plate are respectively fixedly connected to the rear end faces of the two circular rods. The outer wall of the circular rod is rotatably connected to a second straight plate.

[0016] This setting: The second straight plate rotates under force through the bearing on the outer wall of the round rod, and the outer wall of the second straight plate is connected to the threaded bolt, which can fix the inserted automobile axle.

[0017] The present invention proposes a disc-type car flywheel assembly with the following advantages: In the assembly structure, the inner wall of the toothed ring is inserted into the outer wall of the circular block. At this time, the rear of the toothed ring is in contact with the front of the collar, and simultaneously, the square block on the inner wall of the toothed ring is inserted into the inner wall of the groove on the outer wall of the circular block. At this time, the rear of the first straight plate on the front of the toothed ring is in contact with the front of the circular block. Then, the bolt, threaded from right front to rear, passes through the first straight plate and connects with the circular thread on the front of the circular block, completing the fixation of the toothed ring and the circular block. This changes the original separate installation method of the toothed ring. Furthermore, the insertion of the square block into the groove creates a constraint, preventing the toothed ring from rotating on the outer wall of the circular block and reducing the vibration experienced by the bolt on the outer wall of the first straight plate. This prevents the disc-type car flywheel assembly from becoming loose and avoids misalignment of the outer toothed ring of the disc-type car flywheel assembly. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-5 In this embodiment, a disc-type automobile flywheel assembly includes a collar 1 and a circular block 4. The front side of the collar 1 is fixedly connected to the rear end face of the circular block 4. The inner wall of the circular block 1 is machined with a through-hole to facilitate the insertion of the automobile axle. The upper and lower sides of the circular block 4 are respectively machined with grooves 5. The outer wall of the circular block 4 is connected to an assembly structure 2, and the inner wall of the collar 1 is connected to a fixing structure 3.

[0021] Assembly structure 2 includes a toothed ring 201 and a first straight plate 202. The inner wall of the toothed ring 201 is inserted into the outer wall of the circular block 4. When the toothed ring 201 is pulled forward, it can detach from the outer wall of the circular block 4. The front of the toothed ring 201 is fixedly connected to the outer side of the rear end face of multiple first straight plates 202. The upper and lower sides of the inner wall of the toothed ring 201 are respectively fixedly connected to blocks 203. The outer wall of the blocks 203 is inserted into the inner wall of the groove 5. After the outer wall of the blocks 203 is inserted into the inner wall of the groove 5, it restricts the toothed ring 201 and prevents the toothed ring 201 from rotating at an angle on the outer wall of the circular block 4. The inner side of the outer wall of the first straight plate 202 is connected to the front circular thread of the circular block 4 by bolts. The bolts fix the first straight plate 202 and the circular block 4, thereby fixing the position of the toothed ring 201 connected to the first straight plate 202 and preventing the toothed ring 201 from detaching from the outer wall of the circular block 4. By assembling structure 2, the inner wall of the toothed ring 201 is inserted into the outer wall of the round block 4. At this time, the rear of the toothed ring 201 is in contact with the front of the collar 1. Simultaneously, the square block 203 on the inner wall of the toothed ring 201 is inserted into the inner wall of the groove 5 on the outer wall of the round block 4. At this time, the rear of the first straight plate 202 on the front of the toothed ring 201 is in contact with the front of the round block 4. Then, the bolt threaded from right front to rear passes through the first straight plate 202 and is connected to the round hole thread on the front of the round block 4, thus completing the fixation of the toothed ring 201 and the round block 4. This changes the original split installation form of the toothed ring 201. At the same time, the square block 203 and the groove 5 form a constraint, which can prevent the toothed ring 201 from rotating on the outer wall of the round block 4 and reduce the vibration of the bolt on the outer wall of the first straight plate 202, prevent the disc-type car flywheel assembly from loosening, and avoid misalignment of the toothed ring on the outer wall of the disc-type car flywheel assembly.

[0022] Multiple fins 6 are fixedly connected to the front of the circular block 4. The fins 6 are made of copper. The heat generated by the heat source will be quickly transferred to each part of the fins through heat conduction, avoiding heat accumulation on the surface of the heat source. The fixing structure 3 includes a circular plate 301 and a circular rod 302. The outer wall of the circular plate 301 is fixedly connected to the outer wall of the collar 1. The left and right sides of the front of the circular plate 301 are fixedly connected to the rear end faces of the two circular rods 302 respectively. The outer wall of the circular rod 302 is rotatably connected to a second straight plate 303. The second straight plate 303 rotates under force through the bearing on the outer wall of the circular rod 302. At the same time, the outer wall of the second straight plate 303 is connected to a bolt with a circular thread. The inserted automobile axle can be fixed by the bolt.

[0023] Working principle: Disc-type car flywheel assembly assembly: The inner wall of the toothed ring 201 is inserted into the outer wall of the round block 4. At this time, the rear of the toothed ring 201 is in contact with the front of the collar 1. Simultaneously, the square block 203 on the inner wall of the toothed ring 201 is inserted into the inner wall of the groove 5 on the outer wall of the round block 4. At this time, the rear of the first straight plate 202 on the front of the toothed ring 201 is in contact with the front of the round block 4. Then, the bolt is threaded from right front to back through the first straight plate 202 and connected to the round hole thread on the front of the round block 4, thus completing the fixation of the toothed ring 201 and the round block 4. This changes the original split installation form of the toothed ring 201. At the same time, the square block 203 and the groove 5 form a restriction after insertion, which can prevent the toothed ring 201 from rotating on the outer wall of the round block 4 and reduce the vibration of the bolt on the outer wall of the first straight plate 202, preventing the bolt from loosening.

[0024] Disc-type car flywheel assembly and vehicle body installation: The axle of the car is inserted into the inner wall of the circular plate 301. Then, the second straight plate 303 is rotated upward through the outer wall of the circular rod 302, so that the rear of the outer wall of the second straight plate 303 is in contact with the front of the rib plate of the car axle. Then, the bolt is threaded through the second straight plate 303 from front to back and threadedly connected to the rib plate of the car axle, thus completing the installation of the disc-type car flywheel assembly with the car body. At this time, the outer wall of the gear ring 201 is engaged with the pinion of the engine.

[0025] When the engine is started, the starter motor is powered on and rotates. The pinion drives the gear ring 201 to rotate. The rotating gear ring 201, together with the circular block 4, drives the collar 1 to rotate. At this time, the rotating collar 1, together with the circular plate 301, drives the connected car axle to rotate, causing the piston to complete the intake and compression strokes, and finally realizes the engine ignition and start-up. The rotation of the gear ring 201 generates heat. Since the gear ring 201 is used to connect the circular block 4, the heat will be transferred to the outer wall of the circular block 4. However, the front of the circular block 4 is flat and not easy to dissipate heat. At this time, the fins 6 on the outer wall of the circular block 4 can conduct heat out through their own copper material.

[0026] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
