[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0018] Reference Figure 1 one Figure 2 As shown, an output-controllable silicone oil clutch of this embodiment includes a rotatably connected driving shaft 1 and a driven housing 2, wherein the driven housing 2 has a cavity 21, and a partition 22 is provided in the cavity 21. The partition 22 divides the cavity 21 into a storage cavity 221 and a combining cavity 222. The combining cavity 222 is provided with a driving disk 3, which is fixedly connected to the driving shaft 1. The two end surfaces of the driving disk 3 are provided with a plurality of driving rings 31, and the combining cavity 222 is provided with a plurality of driven grooves. 32, the active ring 31 is located in the driven groove 32, the partition plate 22 is provided with an oil inlet hole 41, the oil inlet hole 41 connects the storage chamber 221 and the combination chamber 222, the driven housing 2 is provided with an oil return hole 42, the oil return hole 42 connects the storage chamber 221 and the combination chamber 222, the housing is provided with a reed 51, the storage chamber 221 is provided with a movable piece 52, the movable piece 52 is linked to the reed 51, the oil return hole 42 is provided with a closing mechanism 6, the closing mechanism 6 includes:
[0019] The closing rod 61 is slidably disposed in the oil return hole 42;
[0020] A closing ring 62 is provided on the side of the closing rod 61 and is located in the storage cavity 221;
[0021] The closing spring 63 is disposed in the storage chamber 221 , with one end sleeved on the closing rod 61 and in contact with the closing rod 61 , and the other end in contact with the driven housing 2 .
[0022] Silicone oil is stored in the storage chamber 221. When the silicone oil is stored in the storage chamber 221, the driving shaft 1 rotates and the driven housing 2 remains stationary (under ideal conditions, the driven housing 2 will actually move). As the silicone oil in the coupling chamber 222 increases, the silicone oil fills between the driving ring 31 and the driven groove 32, coupling them together, thereby causing the driving shaft 1 and the driven housing 2 to move in conjunction, and the driven housing 2 can reach a maximum speed of 95% of the driving shaft 1.
[0023] Through the above technical solution, during the operation of the automobile, when the temperature of the engine coolant is too high, the temperature of the air flow blown onto the reed 51 is high, causing the reed 51 to deform, thereby driving the movable piece 52 to move, opening the oil inlet hole 41, and the silicone oil in the storage chamber 221 enters the combining chamber 222 through the oil inlet hole 41, so that the driven housing 2 and the active disc 3 are combined through the silicone oil. When the temperature of the engine coolant is too low, the temperature of the air flow blown onto the reed 51 is low, causing the reed 51 to reset, thereby driving the movable piece 52 to move, closing the oil inlet hole 41, and the silicone oil in the combining chamber 222 returns to the storage chamber 221 from the oil return hole 42. According to the amount of silicone oil in the combining chamber 222, the ratio of the speed of the driven housing 2: the speed of the active shaft 1 can be steplessly adjusted.
[0024] The silicone oil entering the combining cavity 222 moves from the inside to the outside. A closing mechanism 6 is provided in the oil return hole 42. When the engine coolant needs to be cooled quickly, the closing mechanism 6 closes / partially closes the oil return hole 42 to reduce the oil return speed of the silicone oil. The silicone oil continues to enter the combining cavity 222 from the oil inlet hole 41, which can quickly increase the speed ratio of the driven housing 2 and the driving shaft 1, thereby quickly reducing the temperature of the engine coolant.
[0025] The centrifugal force and pressure of the silicone oil push the closing rod 61 to move, thereby opening the oil return hole 42 and allowing the silicone oil to return to the storage chamber 221. When the combined force is insufficient, the closing spring 63 squeezes the closing ring 62 to close the oil return hole 42.
[0026] As an improved specific implementation, an oil return groove 64 is provided on the side wall of the oil return hole 42 , and the oil return groove 64 is communicated with the storage cavity 221 .
[0027] Through the above technical solution, in the process of the silicone oil in the combined cavity 222 returning to the storage cavity 221, the silicone oil first pushes the closing rod 61 to move toward the storage cavity 221, thereby exposing the return oil groove 64, and then flows into the storage cavity 221 through the return oil groove 64.
[0028] The different silicone oil pressures cause the closing rod 61 to be positioned differently, which in turn causes the oil return groove 64 to be opened to different degrees, thereby changing the oil return speed. During the oil return process, the closing rod 61 is always located within the oil return hole 42, fitting closely to the sidewall of the oil return hole 42, providing high stability.
[0029] As an improved specific implementation, the oil return groove 64 is provided with an inclined introduction edge 65 on the side facing the combining cavity 222 .
[0030] Through the above technical solution, the inclined inlet edge 65 allows the silicone oil entering the oil return hole 42 to enter the oil return groove 64 more quickly and smoothly, and then return to the storage chamber 221, so that the oil return efficiency is high.
[0031] As an improved specific implementation, a through hole 66 is provided on the closed ring 62 .
[0032] Through the above technical solution, in the process of silicone oil returning from the combining chamber 222 to the storage chamber 221, the silicone oil first enters the oil return hole 42, then enters the oil return groove 64, and then part of the silicone oil enters the storage chamber 221 from the gap between the closed ring 62 and the driven housing 2, and part of the silicone oil enters the storage chamber 221 from the through hole 66. There are many paths, and the oil return efficiency is high.
[0033] As an improved specific implementation, the position of the through hole 66 corresponds to the position of the oil return groove 64 .
[0034] Through the above technical solution, the position of the through hole 66 corresponds to the position of the oil return groove 64, and the silicone oil that partially leaves the oil return groove 64 can pass through the through hole 66 more smoothly, thereby improving the oil return efficiency.
[0035] As an improved specific implementation, a positioning groove 67 is provided on the closing ring 62 , and one end of the closing spring 63 is located in the positioning groove 67 .
[0036] Through the above technical solution, one end of the closing spring 63 is located in the positioning groove 67, which further improves the stability of the connection between the closing spring 63 and the closing ring 62, thereby improving the stability during use.
[0037] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
