Description

Technical Field

[0001] This utility model relates to the field of coupling transmission device technology, specifically a shock absorption and buffer component for a hybrid power coupling transmission device. Background Technology

[0002] Hybrid power refers to a power system that combines two or more power sources, typically an internal combustion engine and an electric motor. In this way, hybrid power systems can optimize energy use under different driving conditions, thereby improving fuel efficiency, reducing emissions, and enhancing driving performance to some extent. A coupling drive is a mechanical device used to connect two rotating parts together to transmit power. It is mainly used to connect two shafts in a mechanical system to achieve power transmission, torque transmission, or synchronous operation of the shafts. Vibration damping is a key technology in hybrid coupling drive systems, which involves how to effectively reduce vibrations and impacts from different power sources and uneven road surfaces during power transmission.

[0003] In hybrid power systems, the internal combustion engine and electric motor have different power output characteristics. When the internal combustion engine suddenly starts or the torque of the electric motor switches, vibrations may occur. These vibrations not only affect the driving experience but may also damage the transmission system and other mechanical components. To address these issues, the inventors have proposed a vibration damping and buffering component for a hybrid power coupling transmission device. Utility Model Content

[0004] To address the issue that in hybrid power systems, the different power output characteristics of the internal combustion engine and electric motor can cause vibrations when the internal combustion engine suddenly starts or the torque of the electric motor switches, which not only affects the driving experience but may also damage the transmission system and other mechanical components, this invention aims to provide a shock-absorbing and buffering component for a hybrid power coupling transmission device. By incorporating a gas-depressurized shock-absorbing component, gas depressurization can be used for shock absorption and buffering. This gas-depressurized shock-absorbing component can smoothly absorb and dissipate excess energy when the power source switches or the load changes. Furthermore, by designing a second coupling turntable and a first turntable, magnetic coupling transmission can be achieved using fixed magnets externally attached to the second and first coupling turntables.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a shock-absorbing and buffering assembly for a hybrid power coupling transmission device, comprising a support fixing block, a first coupling turntable, a shock-absorbing device, and a power main shaft. A first cylinder is fixedly installed on the outside of the support fixing block. A second fixing block is movably connected to the outside of the first cylinder. The shock-absorbing device is movable outside of the second fixing block. A motor sub-shaft is rotatably connected to the outside of the shock-absorbing device. The motor sub-shaft is fixedly connected to the first coupling turntable. A shock-absorbing fixing block is rotatably connected to the outside of the power main shaft. A venting shock-absorbing assembly is fixedly installed on the outside of the shock-absorbing device. The venting shock-absorbing assembly includes a sliding shock-absorbing column, a shock-absorbing pipe, and a second vent pipe.

[0007] Preferably, a second coupling turntable is fixedly installed on the outside of the motor subshaft, a first turntable is fixedly installed on the outside of the shock-absorbing fixing block, a second turntable is fixedly installed on the outside of the shock-absorbing fixing block, and a fixing magnet is fixedly installed on the outside of the first turntable, the second turntable and the second coupling turntable.

[0008] Preferably, a sliding damping column is fixedly installed on the outside of the damping block, and a damping pipe is fixedly installed on the outside of the damping device, with the sliding damping column and the damping pipe fitting together.

[0012] Preferably, the number of the shock-absorbing pipes and the second air outlet pipe are both two sets and symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a gas relief damping component, gas pressure relief can be used to dampen and buffer the shock. The gas pressure relief damping component can smoothly absorb and dissipate excess energy when the power source is switched or the load changes. The gas pressure relief component can reduce the sudden vibration and impact, making the power transmission process more stable, avoiding the transmission of vibration to the vehicle body or transmission system, and providing a more comfortable driving experience. The gas pressure relief device can effectively alleviate this torque fluctuation and reduce the intensity of vibration.

[0015] 2. In this utility model, by designing a second coupling turntable and a first turntable, magnetic coupling transmission can be achieved by using fixed magnets fixed on the outside of the second coupling turntable and the first turntable. The core feature of magnetic coupling transmission is that power is transmitted from one component to another through a magnetic field without physical contact. This method can avoid the friction and wear caused by traditional mechanical connections, reduce the wear of mechanical components, and reduce the vibration caused by direct contact between mechanical components by transmitting power through a magnetic field.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-5 As shown, this utility model provides a shock-absorbing and buffering assembly for a hybrid power coupling transmission device, including a support fixing block 1, a first coupling turntable 2, a shock-absorbing device 3, and a power main shaft 301. A first cylinder 102 is fixedly installed on the outside of the support fixing block 1. A second fixing block 106 is movably connected to the outside of the first cylinder 102. The shock-absorbing device 3 is movably installed outside of the second fixing block 106. A motor sub-shaft 302 is rotatably connected to the outside of the shock-absorbing device 3. The motor sub-shaft 302 is fixedly connected to the first coupling turntable 2. A shock-absorbing fixing block 304 is rotatably connected to the outside of the power main shaft 301. A venting shock-absorbing assembly is fixedly installed on the outside of the shock-absorbing device 3. The venting shock-absorbing assembly includes a sliding shock-absorbing column 305, a shock-absorbing pipe 308, and a second vent pipe 309.

[0025] The motor subshaft 302 is externally connected to a third fixing block 303, which is externally rotatably connected to a first fixing block 101. The first fixing block 101 is externally slidably connected to a second cylinder 104, and a first spring 105 is fixedly installed on the outside of the first fixing block 101. A limit fixing block 103 is fixedly installed at the end of the first cylinder 102 away from the support fixing block 1.

[0026] By adopting the above technical solution, a limiting block 103 is fixedly installed at the end of the first cylinder 102 away from the supporting fixing block 1, and the first fixing block 101 can be limited by the first cylinder 102.

[0027] The motor subshaft 302 is externally fixedly mounted with a second coupling turntable 204. The shock-absorbing fixing block 304 is externally fixedly mounted with a first turntable 202. The shock-absorbing fixing block 304 is externally fixedly mounted with a second turntable 203. The first turntable 202, the second turntable 203 and the second coupling turntable 204 are all externally fixedly mounted with fixing magnets 201.

[0028] By adopting the above technical solution, fixed magnets 201 are fixedly installed on the outside of turntable 202, turntable 203 and coupling turntable 204. The first coupling turntable 2 and the second turntable 203 can be magnetically coupled by using multiple fixed magnets 201.

[0029] The damping block 304 is externally fixed with a sliding damping column 305, and the damping device 3 is externally fixed with a damping pipe 308. The sliding damping column 305 is in contact with the damping pipe 308.

[0030] By adopting the above technical solution, the sliding damping column 305 is attached to the damping pipe 308, and gas pressure relief can be used for damping and buffering. The gas pressure relief damping component can smoothly absorb and dissipate excess energy when the power source is switched or the load changes.

[0031] The shock-absorbing pipe 308 is externally fixedly installed with a second vent pipe 309, and the second vent pipe 309 has an vent hole 310. The shock-absorbing pipe 308 is externally slidably connected with a third slide rod 311, and a sealing slider 312 is externally fixedly installed on the third slide rod 311. The sealing slider 312 is in contact with the vent hole 310.

[0032] By adopting the above technical solution, the sealing slider 312 fits into the air outlet 310, which can reduce sudden vibrations and impacts, making the power transmission process smoother and preventing vibrations from being transmitted to the vehicle body or transmission system.

[0033] A second spring 313 is fixedly installed on the outside of the sealing slider 312. The end of the second spring 313 away from the sealing slider 312 is fixedly connected to the shock-absorbing pipe 308.

[0034] By adopting the above technical solution, the end of the second spring 313 away from the sealing slider 312 is fixedly connected to the shock-absorbing pipe 308, and the second spring 313 can be used to reset the sealing slider 312.

[0035] A first sliding rod 306 is fixedly installed on the outside of the shock-absorbing fixing block 304, and a second sliding rod 307 is rotatably connected to the outside of the motor subshaft 302. The second sliding rod 307 is slidably connected to the first sliding rod 306.

[0036] By adopting the above technical solution, the sliding connection between the second sliding rod 307 and the first sliding rod 306 allows the first coupling turntable 2 and the second turntable 203 to be coupled and driven by the movement of the second sliding rod 307 and the first sliding rod 306.

[0037] There are two sets of shock-absorbing pipes 308 and two sets of air outlet pipes 309, which are symmetrically distributed.

[0038] By adopting the above technical solution, the stability of the device can be improved by using two sets of shock-absorbing pipes 308 and two sets of air outlet pipes 309, which are symmetrically distributed.

[0039] Working principle: When a hybrid power coupling transmission device shock absorption component is required, when the motor assists the rotation of the internal combustion engine main shaft, the magnetic coupling transmission can be achieved by using the fixed magnet 201 externally fixed to the No. 2 coupling turntable 204 and the No. 1 turntable 202. This method can avoid the friction and wear caused by traditional mechanical connection and reduce the wear of mechanical parts.

[0040] When the internal combustion engine suddenly starts or the torque of the electric motor switches, vibrations are generated, causing the sliding damping column 305 to slide inside the damping pipe 308. Furthermore, the movement of the sliding damping column 305 can drive the sealing slider 312 to move, causing the sliding damping column 305 to compress the air inside the damping pipe 308. The movement of the sealing slider 312 will also release the engagement between the sealing slider 312 and the air outlet 310, allowing the gas to be discharged from the air outlet 310. This allows the gas to be depressurized for shock absorption and buffering. The gas depressurization damping component can smoothly absorb and dissipate excess energy when the power source switches or the load changes. The gas depressurization component can reduce sudden vibrations and impacts, making the power transmission process smoother and preventing vibrations from being transmitted to the vehicle body or transmission system, providing a more comfortable driving experience. The gas depressurization device can effectively alleviate this torque fluctuation and reduce the intensity of vibration.

[0041] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
