Description

Technical Field

[0001] This utility model relates to the field of clutch control technology, and in particular to an intelligent clutch control device based on magnetorheological technology. Background Technology

[0002] Magnetorheological clutches primarily operate based on the magnetorheological effect. They are internally filled with magnetorheological fluid, a smart material composed of micron-sized magnetic particles uniformly dispersed within a carrier fluid. In the absence of an external magnetic field, the magnetorheological fluid exhibits a low-viscosity Newtonian fluid state with good flowability. When a magnetic field is applied, the magnetic particles align along the direction of the magnetic field, forming a chain-like structure, causing the viscosity of the magnetorheological fluid to increase rapidly, transforming it into a viscoplastic body with a certain yield stress.

[0003] The car clutch is a key component in the automotive transmission system, located between the engine and the gearbox. Its main function is to cut off and transmit engine power, allowing the engine's power to be smoothly transmitted to the gearbox, thereby driving the vehicle. It also facilitates gear shifting and allows the engine to be separated from the transmission system when the vehicle is stopped. Existing clutches are divided into mechanical clutches, hydraulic clutches, and electronically controlled clutches. Among them, mechanical clutches are relatively laborious to use, hydraulic clutches rely too much on hydraulic propulsion and have low reliability issues, and electronically controlled clutches have complex parameter adjustments during use, making it inconvenient to set parameters corresponding to the vehicle. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent clutch control device based on magnetorheological technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smart clutch control device based on magnetorheological technology includes a mounting frame, a storage tube on one side of the mounting frame containing magnetorheological fluid, a first coil and a second coil wound around the side wall of the storage tube, a connection mechanism for connecting the first coil and the second coil on one side of the mounting frame, a sealing tube on one side of the mounting frame, a plurality of circumferentially arranged heat dissipation fins fixedly connected to the side wall of the sealing tube, a clutch on one side of the mounting frame, a propulsion shaft passing through the mounting frame and the storage tube, a measuring mechanism for measuring the propulsion pressure of the propulsion shaft on the side wall of the propulsion shaft, and a guiding mechanism for guiding heat away from the clutch on one side of the sealing tube.

[0007] Preferably, the connection mechanism includes two symmetrically arranged connecting wire ends fixedly connected to one side of the mounting frame, and the two connecting wire ends on both sides are respectively connected to the first coil and the second coil.

[0008] Preferably, the side wall of the first coil is fitted with a first barrier tube, and the side wall of the second coil is fitted with a second barrier tube.

[0009] Preferably, the first coil and the second coil are arranged alternately.

[0010] Preferably, the measuring mechanism includes a fixed tube slidably connected to the side wall of the propulsion shaft, a fixed ring fixedly connected to the side wall of the propulsion shaft, a traction spring elastically connected between the fixed tube and the fixed ring, and a sensor fixedly connected to the side wall of the fixed tube.

[0011] Preferably, the guiding mechanism includes a mounting ring fixedly connected to one side of the clutch. The side wall of the mounting ring has multiple circumferentially arranged heat dissipation grooves. The mounting ring is fixedly connected to multiple guide plates located on the side wall of the heat dissipation grooves. The guide plates have an arc-shaped structure.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This utility model is equipped with a storage tube, mounting bracket, first coil, second coil, and propulsion shaft. Due to the extremely rapid response of the magnetorheological fluid to the magnetic field, and the convenient switching between the first and second coils, it can achieve separation and engagement actions faster than a traditional clutch, meeting the needs of vehicles for rapid gear shifting and power switching. At the same time, in conjunction with the propulsion shaft and sensors to calculate the traction force of the traction spring, the propulsion intensity of the magnetorheological fluid can be adjusted according to the user's pedaling force, providing the user with a comfortable user experience.

[0014] 2. This utility model is equipped with a sealing tube, heat dissipation fins, mounting ring, heat dissipation groove and guide plate. The sealing tube and heat dissipation fins can provide a rapid heat dissipation effect for the storage tube inside the sealing tube, while blocking the heat transfer of the clutch.

Detailed Implementation

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] Reference Figure 1-3 A smart clutch control device based on magnetorheological technology includes a mounting frame 1. A storage tube 2 is provided on one side of the mounting frame 1. The storage tube 2 contains magnetorheological fluid. A first coil 3 and a second coil 5 are wound around the side wall of the storage tube 2. The first coil 3 and the second coil 5 are staggered. A first blocking tube 4 is sleeved on the side wall of the first coil 3, and a second blocking tube 6 is sleeved on the side wall of the second coil 5.

[0021] The mounting bracket 1 has a connection mechanism for connecting the first coil 3 and the second coil 5 on one side. The connection mechanism includes two symmetrically arranged connecting wire ends 9 fixedly connected to one side of the mounting bracket 1. The two connecting wire ends 9 on both sides are respectively connected to the first coil 3 and the second coil 5.

[0022] A sealing tube 7 is provided on one side of the mounting bracket 1. Multiple circumferentially arranged heat dissipation fins 8 are fixedly connected to the side wall of the sealing tube 7. A clutch 11 is provided on one side of the mounting bracket 1. A propulsion shaft 10 is provided through the mounting bracket 1 and the storage tube 2. A measuring mechanism for measuring the propulsion pressure of the propulsion shaft 10 is provided on the side wall of the propulsion shaft 10. The measuring mechanism includes a fixed tube 15 slidably connected to the side wall of the propulsion shaft 10. A fixed ring 16 is fixedly connected to the side wall of the propulsion shaft 10. A traction spring 17 is elastically connected between the fixed tube 15 and the fixed ring 16. A sensor 18 is fixedly connected to the side wall of the fixed tube 15.

[0023] A guide mechanism for guiding heat from the clutch 11 is provided on one side of the sealing tube 7. The guide mechanism includes a mounting ring 12 fixedly connected to one side of the clutch 11. Multiple circumferentially arranged heat dissipation grooves 13 are opened on the side wall of the mounting ring 12. Multiple guide plates 14 are fixedly connected to the side wall of the heat dissipation grooves 13 on the mounting ring 12. The guide plates 14 have an arc-shaped structure.

[0024] When using this utility model, such as Figure 1-3 As shown, during use, the movement of the propulsion shaft 10 first drives the movement of the fixed ring 16 to pull the traction spring 17. The sensor 18 measures and calculates the traction force, i.e., measures the force applied by the user when pressing the clutch 11. This measurement serves as the basis for adjusting the feedback intensity of the magnetorheological fluid in the storage tube 2, providing the user with a comfortable driving experience. At this time, the first coil 3 and the second coil 5 are connected via the connecting wire 9. The connection states of the first coil 3 and the second coil 5 are: first coil 3 connected, second coil 5 disconnected; first coil 3 connected, second coil 5 connected; first coil 3 disconnected, second coil 5 connected; and both disconnected. The configuration, with the first coil 3 and the second coil 5 arranged alternately, allows for control and adjustment of the required magnetic force of the magnetorheological fluid within the storage tube 2. The first barrier tube 4 and the second barrier tube 6 separate the first coil 3 and the second coil 5, preventing direct contact and short circuits, and providing support and protection. During use, the heat generated by the magnetorheological fluid is transferred to the mounting ring 12 through the sealing tube 7 and the heat dissipation fins 8, and then conducted to the outside through the heat dissipation groove 13 and the guide plate 14. At the same time, the guide plate 14 can conduct and guide the heat generated during the operation of the clutch 11, preventing it from affecting the temperature of the magnetorheological fluid.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
