Abstract
The utility model relates to a shape memory alloy fan clutch for a vehicle; the shape memory alloy fan clutch is manufactured by utilizing the functional material. Because the characteristic that the shape memory alloy deforms under the specified temperature is used, a shape memory alloy wire spring is installed at the center of a water pump shaft which is sensitive to the cooling circulating water temperature of the vehicle; the shape memory alloy wire spring is served as the temperature-sensing element and the engaging and disengaging power source of a novel clutch. The utility model adopts two interfaces which are a cone type interface and an inserting type interface, so the utility model having simple structure and low cost saves the energy more.
Description
The utility model is a kind of internal-combustion engine fan clutch that utilizes the marmem manufacturing.
Temperature-sensitive silicon oil filled fan clutch and electromagnetic type fan clutch now have been applied to automotive industry.Silicone oil formula fan clutch is so as to the variation of silicone oil to environment temperature, controls the clutch of radiator cooling fan automatically.Electromagnetic type is to measure the height of cooling water water temperature with heat responsive element, utilizes electromagnetic induction or electromagnetism adhesive to finish the clutch of cooling fan then.Thereby its purpose all is the working life of improving motor for the cooling water water temperature that reaches fuel-economizing, noise reduction and assurance motor.With regard to these two kinds of clutches, electromagnetic type is quick on the draw, accurately to the water temperature of cooling water, but will consume the available energy electric energy, and manufacture cost is also high.The silicone oil formula is not so good as the electromagnetic type sensitivity to the reacting condition of water temperature, accurately, but it does not consume available energy, but its complex structure, the manufacture cost height, after just improving, the better simply silicon oil filled fan clutch of structure, the silicon oil filled fan clutch (patent No. 85203125u) of holding oil scraping pin as Chinese No. 2 Automobile Factory, though added oil scraping pin, improved the oil return completeness of traditional silicon oil filled fan clutch, so that separated the much lower of rotating ratio conventional construction, thereby the intensification of clutch is also low, be of value to the life-span of clutch and the design of radiating fin, it is lower to reach the simple cost of processing, can be on the whole, structure is still complicated, and manufacture cost is still high.
The purpose of this utility model is for the length of getting two kinds of conventional clutch, restrains its weak point, utilizes the marmem manufacturing to be quick on the draw, accurately, not consume the fan clutch of available energy, simple in structure, low cost of manufacture.
The design's main design is to utilize the characteristics of marmem to the reaction of assigned temperature distortion, and it is contained in water pump water temperature sensitive part, utilize its energy of deformation promote fan clutch special clutch interface device, finish clutch.
Structure of the present utility model can be illustrated in conjunction with the accompanying drawings, and Fig. 1 is the structural representation with marmem fan clutch of slotting formula interface.
Among Fig. 1 12 and Fig. 3 represent the special hollow water pump oil that the utility model adopts, insert a driving lever 11 at the hollow shaft center, the driving pin 10 that its bar front end has a specified structure as shown in Figure 2, shape-memory alloy wire spring 16, just put after drive link, fixing by back locking nut 17, when temperature lower (being lower than the deformation temperature that the memory alloy wire spring is set), because the shape-memory alloy wire spring is softer, the backspring 7 promotion driving levers that fastened on driving pin 10 by backspring seat 8 move backward, make the compression of shape-memory alloy wire spring, at this moment the driving pin on the driving lever 10 fall back on can not with transmission interface 9 position contacting, if at this moment belt pulley 1, driving hollow water pump spindle 12 and other parts rotates, the fans support 2 that separates by bearing 3, bearing support 4, rotary connector 9 and fans 5 can be with the belt pulley high speed rotating.At this moment fan can only owing to the frictional force in the bearing produce do not have the air working angles, wind-force is very little slowly runs.When water temperature in the water pump changes high, marmem is in more than the deformation temperature, at this moment the shape-memory alloy wire spring begins to expand, promote driving lever 11, compression backspring 7, driving pin 10 is inserted in the rotary connector 9, at this moment driving lever is along with backspring seat 8 driven rotary of belt pulley rotation, it also passes to interface 9 to rotation, wherein driving pin 10, backspring seat hole is consistent as shown in Figure 2 with transmission interface holes shape, at last fans support 2 and fans 5 on the bearing are passed in this rotation, thereby made fan with the belt pulley high speed rotating.
Figure 3 shows that the schematic representation of tapered transmission interface clutch structure, when water temperature was higher than assigned temperature in the water pump, the shape-memory alloy wire spring just was in more than the deformation temperature.At this moment the memory alloy wire spring expands, promoting driving lever 11 compression backsprings 7 and as shown in Figure 6 to basin shape transmission interface 23() direction moves, there are driving pin square toes 22 in the place ahead at the driving pin 10 of driving lever, a taper gear frame 18 shown in Figure 5 is housed on the driving pin square toes, 4 cylinder driving pins 19 are arranged on it, expansion along with the shape-memory alloy wire spring, driving lever promotes taper gear frame 18 and inserts basin shape interface gradually, when cylinder driving pin 19 has just contacted with basin shape interface, because the friction and the collision of the high point of cylinder driving pin and basin shape interface inwall, driving pin drive basin shape interface and interface cover bucket 21 and fans support 2 and fans 5 are quickened gradually, expansion along with the memory alloy wire spring, the rotating speed of fans and the rotating speed of belt pulley are gradually synchronous suddenly, last whole taper gear frame 18 and cylinder driving pin insert in the basin shape interface fully, fan just rotates synchronously with belt pulley, when water temperature in the water pump is low, backspring promotes driving lever backward, and the memory alloy wire spring of compression deliquescing, taper gear frame and cylinder driving pin are separated with basin shape interface, the clutch of the same kind of interface is the same, and fan has only low speed, the rotation that wind-force is very little.
Fig. 1 is the structural representation that the marmem fan clutch has slotting formula interface.
Fig. 2 is a part position schematic representation of inserting the formula interface.
Fig. 3 is hollow water pump spindle.
Fig. 4 is the interface structure schematic representation that the marmem fan clutch has taper transmission interface.
Fig. 5 and Fig. 6 are the taper gear frame in the taper transmission interface and the structural representation of basin shape interface
Among its figure: 6---the pin cap

Effect of the present utility model as mentioned above, owing to adopt marmem as temp-sensing element and the engaging power source of clutch, particularly shape-memory alloy wire is placed on to water temperature sensitive pump shaft center with to the particular design of clutch interface, Modern Internal-Combustion Engine is minimum, simple in structure with manufacturing cost in the fan clutch, energy-saving effect is best thereby reach, so that the most practical a kind of.
