Description
Technical Field
[0001] This utility model relates to the field of silicone oil clutch technology, specifically to a novel high-frequency silicone oil clutch valve plate structure with a golden ratio leveling. Background Technology
[0002] Silicone oil clutches, as fluid transmission devices that utilize the viscosity of silicone oil to transmit torque, are widely used in vehicle cooling systems, mechanical transmissions, and other fields. They achieve torque transmission and disconnection by controlling the flow of silicone oil into the working chamber through valve plates. As the core control element, the dynamic sealing performance of the valve plate directly determines the clutch's working efficiency and reliability.
[0003] Traditional silicone oil clutch valve plates typically consist of an integrated structure comprising an armature, a bent portion, and a sealing portion, with the sealing portion engaging with the valve port to achieve a seal. However, such valve plates have inherent design flaws: when the clutch is used in high-frequency conditions (e.g., 10-30 Hz), the centrifugal force generated by the high-speed rotation of the valve plate increases significantly, causing severe vibration at the sealing end due to uneven force distribution. This vibration not only disrupts the tight seal, leading to silicone oil leakage and reduced torque transmission efficiency, but also easily causes vibration noise and component wear, severely limiting the clutch's application under high-frequency conditions. Current technologies primarily design valve plates for low-frequency conditions (e.g., 1-3 Hz), lacking specific structural optimizations for balancing centrifugal force under high-speed rotation. Therefore, they are difficult to adapt to high-frequency operating requirements, becoming a bottleneck in improving clutch performance and applicability.
[0004] In summary, providing a silicone oil clutch valve plate that can effectively suppress high-speed vibration, improve sealing stability, and adapt to high-frequency operating conditions has become a technical problem that urgently needs to be solved in this field. Utility Model Content
[0005] In view of the shortcomings in the prior art, this utility model provides a novel high-frequency silicone oil clutch valve plate structure with a golden ratio leveling.
[0006] The technical solution adopted in this utility model is: a novel high-frequency silicone oil clutch valve plate structure with golden ratio leveling, including a valve plate body, the armature valve plate body having an armature, a bent part and a sealing part, the armature having a shaft hole, the valve plate body also including a counterweight part, the counterweight part being located at one end away from the sealing part, and including an extension part extending obliquely to the same side as the sealing part and a leveling end connected to the extension part, the counterweight part being configured to generate a leveling torque that balances the centrifugal torque of the sealing part when the valve plate rotates.
[0007] Furthermore, the ratio of the distance (L1) from the end of the leveling end to the center of the shaft hole to the distance (L2) from the sealing part to the center of the shaft hole ranges from 1:1.55 to 1:1.8.
[0008] Furthermore, the counterweight, armature, bending, and sealing parts are integrally formed by a stamping process.
[0009] Furthermore, the distance ratio (L1:L2) is 1:1.6 to 1:1.7.
[0010] Furthermore, the leveling torque (M1) generated by the counterweight and the centrifugal torque (M2) generated by the sealing part satisfy the following relationship: M1 = m1 × L1 and M2 = m2 × L2, Where m1 is the weight of the counterweight part below the lower surface of the armature, and m2 is the weight of the bent and sealing parts below the lower surface of the armature; The ratio of M1 to M2 ranges from 1:1.65 to 1:1.75.
[0011] Furthermore, the armature is located on one side of the counterweight and is fixed with a spring piece, on which a mounting block is fixed.
[0012] Furthermore, the included angle α between the extension and the armature is 120-150°, and the included angle b between the bent portion and the armature is 100-130°.
[0013] The beneficial effects of this utility model are: 1. Effectively suppresses high-frequency vibration and improves sealing reliability: The leveling torque (M leveling) generated by the counterweight and the centrifugal torque (M centrifugal) generated by the sealing part are balanced with each other, so that the valve plate maintains dynamic stability when rotating at high speed (corresponding to 10-30 Hz high frequency conditions), which fundamentally eliminates the vibration phenomenon at the sealing end, ensures the tight fit between the valve port and the sealing surface, and significantly improves the sealing performance and working reliability of the silicone oil clutch.
[0014] 2. Expanding the operating frequency range to meet high-performance requirements: The optimized torque balance design enables the valve plate to stably adapt to the high-frequency operating environment of 10-30 Hz, overcoming the limitation of traditional valve plates that are only suitable for low-frequency conditions of 1-3 Hz. This greatly expands the application scenarios of silicone oil clutches and meets the needs of modern high-power density transmission systems for high-frequency response and high-precision control.
[0015] 3. Scientific structural design and significant performance optimization: The ratio of the lever arm length from the leveling end to the sealing end to the center of rotation (e.g., 46.3mm:77.2mm ≈ 1:1.67) approximately conforms to the golden ratio. This optimized design enables the overall structure of the valve plate to achieve the best state in terms of mechanical performance and spatial layout, which not only ensures the balance effect, but also avoids problems such as inertial delay caused by excessive weight increase.
[0016] 4. One-piece molding structure, reliable and easy to manufacture: The counterweight, armature, bending and sealing parts can be integrally molded by stamping and other processes, with high structural strength and good consistency. No complicated assembly is required, which reduces manufacturing costs and ensures the stability and reliability of product performance.
[0017] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0024] This invention provides a novel high-frequency silicone oil clutch valve plate structure with a golden ratio leveling.
[0025] In this embodiment, refer to Figure 1-3The novel high-frequency silicone oil clutch valve plate structure with golden ratio leveling includes a valve plate body. The armature valve plate body has an armature 1, a bent portion 2, and a sealing portion 3. The armature 1 is provided with a shaft hole 4. The valve plate body also includes a counterweight portion. The counterweight portion is located at one end away from the sealing portion and includes an extension portion 5 that extends obliquely in the same direction as the sealing portion and a leveling end 6 connected to the extension portion 5. The counterweight portion is configured to generate a leveling torque that balances the centrifugal torque of the sealing portion when the valve plate rotates.
[0026] In the above technical solution, a counterweight is added, located at the end of the valve body furthest from the sealing part. The counterweight includes an extension extending obliquely towards the same side as the sealing part and a leveling end connected to the extension. This design allows the leveling end to generate a leveling torque that balances the centrifugal torque of the sealing part when the valve rotates. By adding the counterweight and leveling end, the valve can better balance the torques at both ends during high-speed rotation, reducing vibration and thus improving sealing performance. This design is particularly suitable for high-frequency operating conditions and can effectively improve the working efficiency and reliability of the silicone oil clutch.
[0027] Specifically, the ratio of the distance (L1) from the end of the leveling end to the center of the shaft hole to the distance (L2) from the sealing part to the center of the shaft hole ranges from 1:1.55 to 1:1.8.
[0028] In this embodiment, the ratio of the distance from the leveling end to the distance from the sealing part to the center of the shaft hole is between 1:1.55 and 1:1.8, which is close to the golden ratio (1:1.618). This optimizes the lever arm layout and makes the distribution of the balancing torque most uniform.
[0029] Optimizing the mechanical structure reduces localized stress concentration caused by lever arm imbalance, extending valve plate life. Furthermore, improved dynamic response allows for rapid attainment of equilibrium under high-frequency rotation, shortening stabilization time. This also enhances sealing performance.
[0030] Specifically, the counterweight, armature, bending part, and sealing part are integrally formed by stamping process.
[0031] In this embodiment, the counterweight, armature, bending part and sealing part are integrally formed by stamping process, eliminating assembly gaps, ensuring rigid connection between components, which helps to simplify the manufacturing process and improve production consistency.
[0032] Specifically, the distance ratio (L1:L2) is 1:1.6 to 1:1.7.
[0033] In this embodiment, the ratio range is further narrowed to ensure precise matching between centrifugal force and balancing force, reducing the flutter amplitude by more than 40% under 30Hz operating conditions, improving the sealing surface fit, and reducing energy loss caused by vibration and friction.
[0034] Specifically, the leveling torque (M1) generated by the counterweight and the centrifugal torque (M2) generated by the sealing part satisfy the following relationship: M1 = m1 × L1 and M2 = m2 × L2, Where m1 is the weight of the counterweight part below the lower surface of the armature, and m2 is the weight of the bent and sealing parts below the lower surface of the armature; The ratio of M1 to M2 ranges from 1:1.65 to 1:1.75.
[0035] In this embodiment, the relationship between the leveling torque and the centrifugal torque is quantified by formula, ensuring the balance between the leveling torque and the centrifugal torque. By precisely controlling the ratio of the leveling torque to the centrifugal torque, the stability of the valve plate during high-speed rotation can be ensured, vibration can be reduced, and sealing performance can be improved, thereby improving the overall performance and reliability of the silicone oil clutch.
[0036] Specifically, the armature is located on one side of the counterweight and is fixed with a spring piece 7, and a mounting block 8 is fixed on the spring piece.
[0037] In this embodiment, the armature is located on one side of the counterweight and is fixed with a spring clip, on which a mounting block is fixed. This design facilitates the installation and fixation of the valve plate, improving the convenience and reliability of installation, while also contributing to the overall structural strength of the valve plate.
[0038] Specifically, the angle α between the extension and the armature is 120-150°, and the angle b between the bent portion and the armature is 100-130°.
[0039] In this embodiment, the mechanical properties of the valve plate during operation can be optimized, improving its stability and durability at high speeds, thereby enhancing the overall performance of the silicone oil clutch. Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
