Abstract
The utility model discloses a silicon oil fan clutch which comprises a shell (1) and a front cover (2) fixed with the shell (1) integrally, wherein, the outer surface of the front cover (2) is also provided with a temperature sensing ring (3). The utility model is characterized in that the outer circumference of the temperature sensing ring (3) is provided with a protective cover with an opening (4) connected to the outer wall of the front cover (2). Compared with the prior art, the utility model has the advantages that: the protective cover can protect the temperature sensing ring from external collision and friction, can protect the temperature sensing ring form being distorted, has no influence on the whole performance of the product, ensures that the performance and the service life of the product are assured for a long time; the whole clutch has compact and rational structural design, a simple structure, easy assembly and production, and is suitable for popularization and application on automobile engines.
Description
Technical field
The utility model relates to a kind of engine-cooling system assembly, relates in particular to a kind of silicon oil filled fan clutch that has temperature feeling ring.
Background technique
Existing automobile is from silicon oil filled fan clutch, its working principle is by temperature sensibility the hot load state of motor to be converted into to rotatablely move, when the motor overburdening, drive the valve block rotation with valve open, and then silicone oil is constantly circulated between working room and accumulator, carry out high speed rotating thereby drive fan, make motor in time obtain cooling; When engine load was low, the silicone oil of accumulator no longer flowed to the working room, and drive fan and carry out low speed rotation this moment, played the effect of balanced engine load.
Domestic and international employed silicon oil filled fan clutch mostly is to have temperature feeling ring at present, temperature feeling ring is a kind of core component on the silicon oil filled fan clutch product, their general temperature feeling rings that adopts are the circle types, it is a kind of spiral line type bimetallic strip structure, directly be contained on the protecgulum of silicon oil filled fan clutch, be in the outermost end of product, no matter in packing, transportation and using process, extraneous collision, the as easy as rolling off a log line style of temperature feeling ring that causes of friction change, thereby influence the overall performance and the working life of clutch.
With reference to Chinese utility model patent: ZL93201277.9, a kind of " taking back the silicon oil filled fan clutch of oil groove and curved radiating fin " (publication number: CN2158922Y) is disclosed, adopt the linear bimetallic strip structure of a kind of spiral as temperature sensibility in this patent, the temperature sensibility of this structure causes extraneous collision easily and causes linear the change, thereby influences the integrity energy charge working life of clutch.
Chinese for this reason utility model patent: ZL01252855.2 and ZL02216970.9 all disclose a kind of silicon oil filled fan clutch that improves structure, by the improvement to the temperature sensibility structure, thereby reduce the influence that extraneous collision brings.But above-mentioned improvement also is not very perfect, and extraneous serious collision still can cause the reduction of clutch overall performance.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of can avoiding to set up a safety cover outward by temperature feeling ring and realize because extraneous collision or friction cause the silicon oil filled fan clutch of temperature feeling ring metaboly at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of silicon oil filled fan clutch; comprise that housing reaches the protecgulum that is fixed in one with housing; the outer surface of protecgulum also is provided with temperature feeling ring, it is characterized in that described temperature feeling ring periphery is provided with the perforate safety cover that is connected on the preceding cover outer wall.
Described perforate safety cover has mesh, and safety cover can be connected on the preceding cover outer wall by threaded or concavo-convex snapping.
Compared with prior art; advantage of the present utility model is: safety cover can protect temperature feeling ring to avoid extraneous collision, friction; can not make the temperature feeling ring distortion; and do not influence the overall performance of product; product performance and working life are ensured for a long time; whole clutch configuration is compact to design rationally, and simple in structure, easy assembling production is adapted at promoting the use of on the motor car engine.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment; With reference to shown in Figure 1.
Silicon oil filled fan clutch in the present embodiment comprises housing 1; protecgulum 2; active plate 11; follower plate 12; bearing 5; valve block 7; temperature feeling ring 3; the perforate safety cover 4 of temperature feeling ring; bearing pin sealing 6; bearing pin 8; driving shaft 9; rectangular seal 10 and silicone oil; it is fixed with driving shaft 9 by bearing 5 in the middle of housing 1; be fixed with active plate 11 on the driving shaft; protecgulum 2 is fixed together with housing 1; follower plate 12 is in protecgulum inside; with space segmentation between protecgulum 2 and the housing 1 be the front at silicone oil vestibule 14 in the protecgulum and back the engagement vestibule 13 in housing; engagement vestibule 13 is communicated with the silicone oil vestibule 14 of protecgulum by connected pore channel 16, between engagement 13 li active plates 3 of vestibule and housing 1 end face teeth groove cooperating structure 15 is arranged.
Temperature feeling ring 3 peripheries are provided with the safety cover 4 that is connected on protecgulum 2 outer walls, with reference to shown in Figure 2, are evenly equipped with mesh 41 on the safety cover 4, and safety cover 4 is connected on protecgulum 2 outer walls by threaded.Also can adopt in the prior art Placement commonly used as concavo-convex snapping etc.
The valve block 7 that temperature feeling ring 3 drives in protecgulum 2 the inside silicone oil vestibules moves, valve block 7 again with follower plate 12 on valve opening open and close and cooperate.
Claims (3)
1. silicon oil filled fan clutch; comprise that housing (1) reaches the protecgulum (2) that is fixed in one with housing (1); the outer surface of protecgulum (2) also is provided with temperature feeling ring (3), it is characterized in that described temperature feeling ring (3) periphery is provided with the perforate safety cover (4) that is connected on protecgulum (2) outer wall.
