Description
Technical field
This utility model relates to clutch field, particularly relates to the bimetal leaf of a kind of fan clutch.
Background technology
Silicon oil filled fan clutch is mainly used on automobile, and in the process of moving, due to the change of environmental condition and operating condition, the thermal conditions of electromotor is also changing automobile, it is necessary to regulate the intensity of cooling of electromotor at any time.During the broiling summer, electromotor is at low speed, big working under load, the temperature of coolant is significantly high, fan should high speed rotating to increase cooling air quantity, strengthen the heat-sinking capability of radiator, and in cold winter, when coolant temperature is relatively low, or when galloping has powerful head-on wind to blow over radiator, fan works on and just becomes meaningless, not only consumption of engine power in vain, but also produces very big noise, therefore, at any time its intensity of cooling is regulated according to the thermal conditions of electromotor and just seemed particularly significant.
In order to realize the Intelligent adjustment with radiator temperature of fan, can blower pulley and cooling fan between device silicon oil filled fan clutch, and silicon oil filled fan clutch needs employing bimetal leaf to carry out the monitoring of temperature, and common bimetal leaf makes complex process, structural stability is poor, it is necessary to improve.
Utility model content
This utility model, mainly solving the technical problems that provide the bimetal leaf of a kind of fan clutch, reduces manufacture difficulty, lift structure intensity and susceptiveness.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide the bimetal leaf of a kind of fan clutch, including: the bimetallic strip of helical structure, fixing end and movable end, described fixing end is arranged on the outer front end of bimetallic strip, described movable end is arranged on the inside end of bimetallic strip, described bimetallic strip includes inner side active layers and outside passive layer, the arranged outside of described inner side active layers has a dovetail groove, described outside passive layer is arranged in dovetail groove, and the lateral surface of described outside passive layer is provided with fluting.
In one preferred embodiment of this utility model, described bimetallic strip, fixing end and movable end are integrated.
In one preferred embodiment of this utility model, described fluting is disposed on the lateral surface of outside passive layer.
In one preferred embodiment of this utility model, the coefficient of expansion of described inner side active layers is higher than the coefficient of expansion of outside passive layer.
In one preferred embodiment of this utility model, described inner side active layers is copper alloy layer, and described outside passive layer is iron alloy layer.
The beneficial effects of the utility model are: the bimetal leaf of a kind of fan clutch that this utility model is pointed out, outside passive layer is arranged in the dovetail groove of inner side active layers, then bending obtains bimetal leaf, manufacturing simplicity, structural strength is high, durable in use, and the lateral surface of outside passive layer is provided with fluting, the deformation drag of inner side active layers can be reduced, promote the sensitivity of thermoinduction action, be suitable for fan clutch and use.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of bimetal leaf one preferred embodiment of a kind of fan clutch of this utility model；
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1 to Fig. 2, this utility model embodiment includes:
A kind of bimetal leaf of fan clutch, including: the bimetallic strip 1 of helical structure, fixing end 12 and movable end 11, described fixing end 12 is vertically set on the outer front end of bimetallic strip 1, described movable end 11 is vertically set on the inside end of bimetallic strip 1, described bimetallic strip 1, fixing end 12 and movable end 11 are integrated, 12 bimetallic strips 1 of fixing end are utilized to be fixed on the protecgulum of fan clutch, movable end 11 is arranged in the valve block rotating shaft of fan clutch, thermal deformation by bimetallic strip 1, it is achieved the rotation of valve block rotating shaft.
Described bimetallic strip 1 includes inner side active layers 2 and outside passive layer 3, the arranged outside of described inner side active layers 2 has a dovetail groove 21, and described outside passive layer 3 is arranged in dovetail groove 21, is then pressed into the bimetallic strip 1 of helical structure, sound construction, is not easily destroyed.
Being provided with fluting 31 on the lateral surface of described outside passive layer 3, described fluting 31 is disposed on the lateral surface of outside passive layer 3.Fluting 31 reduces the non-deformability of outside passive layer 3, thus decreasing the damping of inner side active layers 2 thermal deformation so that the thermal deformation of bimetallic strip 1 is highly sensitive.
The coefficient of expansion of described inner side active layers 2 is higher than the coefficient of expansion of outside passive layer 3, described inner side active layers 2 is copper alloy layer, described outside passive layer 3 is iron alloy layer, when temperature rises to more than 35 DEG C, the thermal expansion deformation of inner side active layers 2 exceedes outside passive layer 3, and cause the swing of movable end 11, highly sensitive.
In sum, the bimetal leaf of a kind of fan clutch that this utility model is pointed out, sound construction, produce facility, highly sensitive, ruggedness is good, is suitable for various silicon oil filled fan clutch and uses.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in scope of patent protection of the present utility model.
