Description
Technical field
The present invention relates to a kind of mistake proofing silicon oil clutch.
Background technique
Silicon oil filled fan clutch as medium, utilizes the full-bodied characteristic transmitting torque of silicone oil with silicone oil.Utilize the temperature of radiator back air, control the separation and the joint of fan clutch through temp-sensitive apparatus automatically.When temperature was hanged down, silicone oil did not flow, and fan clutch separates, and rotation speed of the fan slows down, and was idle running basically.When temperature was high, the viscosity of silicone oil combined fan clutch, so fan and water pump spindle rotate together, played the effect of regulating engine temperature.
Present silicon oil filled fan clutch is because the restriction of structure; Clutch and fan assembling dislocation often appears in assembling process; Cause road, back processed complex, receive the thermal sensitive piece structural constraint simultaneously, the clutch speed of response is slow; And since machining accuracy etc. problem cause silicone oil to reveal, under silicone oil in the clutch contains the situation of quantity not sufficient, can directly influence the working efficiency of clutch.
Summary of the invention
The object of the present invention is to provide a kind of oil sealing property good, speed of response is fast, controls stable mistake proofing silicon oil clutch.
For achieving the above object, the technological scheme that the present invention adopted is: comprise end cap, housing, active plate, follower plate, driving shaft, thermal sensitive piece, oil sealing, end cap and housing riveted joint; Thermal sensitive piece is fixed on the end cap exterior edge face, is provided with sealing cover between end cap and the thermal sensitive piece, and follower plate and valve block are formed in one; Be fitted on the end cap interior edge face through the positioning hole on the follower plate, the cavity between follower plate and the end cap is an oil storage chamber, and silicone oil is housed in it; Cavity between follower plate and the housing is an active chamber, has oil inlet hole, thermal sensitive piece to receive the temperature variation distortion to drive the valve block switch through valve shaft on the follower plate; The control oil inlet hole opens and closes, and active plate is fixedly connected with driving shaft, and driving shaft one end is contained on the housing through bearing; The driving shaft the other end is connected with end cap; The joint of driving shaft and end cap is provided with an oil sealing, has guaranteed the sealing between end cap and the main shaft through oil sealing is set, and prevents leakage of oil.Increase the mistake proofing design that fan is installed on the housing, reduced the probability of assembly defect.The thermal sensitive piece intermediate shape is the circle of hollow, and distortion is steadily controlled more stable.
Described thermal sensitive piece is connected with end cap through draw-in groove, and fixes through viscose glue and end cap, and the thermal sensitive piece intermediate shape is the circle of hollow.
This housing is provided with one recessed portion.
Active plate and flange are riveted into one.
Because the employing of technique scheme, the present invention compared with prior art has the following advantages: 1. the joint of driving shaft and end cap is provided with oil sealing, guarantees sealing between end cap and the main shaft, prevents leakage of oil;
2. fan fixed hole place has increased the mistake proofing design on the housing, guarantees the uniqueness of installation direction when fan is installed, and has reduced the probability of assembly defect.
3. the thermal sensitive piece intermediate shape is the circle of hollow, design more reasonable, and the valve block distortion is steadily controlled more stable.
4. active plate and the flange formula that is riveted into one, product is smooth, and performance is more superior.

Embodiment
As shown in Figure 1, this mistake proofing silicon oil clutch comprises end cap 12, housing 3, active plate 4, follower plate 6, driving shaft 1, thermal sensitive piece 10, oil sealing 7; End cap 12 and housing 3 riveted joints, thermal sensitive piece 10 is fixed on end cap 12 exterior edge faces, is provided with sealing cover between end cap 12 and the thermal sensitive piece 10; Follower plate 6 is formed in one with valve block, is fitted on end cap 12 interior edge faces through the positioning hole on the follower plate 6, and the cavity between follower plate and the end cap 12 is an oil storage chamber; Silicone oil 5 is housed in it, and the cavity between follower plate 6 and the housing 3 is an active chamber, on the follower plate 6 oil inlet hole is arranged; Thermal sensitive piece 10 receives the temperature variation distortion to drive the valve block switch through valve shaft 9; The control oil inlet hole opens and closes, and active plate 4 is fixedly connected with driving shaft 1, and driving shaft 1 one ends are contained on the housing 3 through bearing 2; Driving shaft 1 the other end is connected with end cap 12, and driving shaft 1 is provided with an oil sealing 7 with the joint of end cap 12.
As shown in Figure 2, one recessed portion 13 on this housing 3, when fan and the installation of this clutch mistake, fan will be inconsistent with this recessed portion 13, can't accomplish installation, reduce the generation of road, back mistake.
As shown in Figure 3, these thermal sensitive piece 10 intermediate shapes are the circle of hollow, have reduced the intermediate portion temperature sensing material to the constraint of circumference distortion of materials, and when receiving temperature, the thermal sensitive piece deformation response is fast, and distortion is steady and amount of deformation is big, highly sensitive, controls more stable.
As shown in Figure 4, this active plate 4 is riveted into one with flange 14, and active plate 4 has moved to flange 14 places in the part of the force in the process that press-fits with driving shaft 1 like this; Flange 14 place's thickness are big, and volume is little, and stress deformation is little; Thereby avoided active plate 4 distortion, made product smooth, performance is more superior.
