Abstract
A silicone oil fan clutch capable of controlling a disengagement rotating speed comprises a driving shaft, a driving plate, a casing, a front cover, a driven plate, a silicone oil outlet hole in the driven plate, an oil storage cavity between the driven plate and the front cover, a working chamber between the driven plate and the casing, a valve piece and the like, and is characterized in that an oil-bearing convex ring is arranged on the excircle of the driving plate; and a plurality of oil blocking grooves are formed in the oil-bearing convex ring. The oil-bearing convex ring and the oil blocking grooves can guarantee that silicone oil necessary for maintaining the lowest rotating speed is still kept in the working chamber when the clutch is in disengagement, and the oil-bearing area of the driving plate can be enlarged or reduced through adjusting parameters such as the width of the oil-bearing convex ring and the number and the inclined angles of the oil blocking grooves, so as to effectively control the disengagement rotating speed of the clutch. The silicone oil fan has the advantages of simple structure, reasonable design, accuracy in control and simplicity in implementation, can effectively control the lowest rotating speed of the disengaged clutch to be within the range of 500-750 r/min, is suitable to be popularized and used in trucks, and has bigger practical value and popularization value.
Description
Technical field
The utility model relates to and being applied in the car engine cooling system, is installed in the improvement of motor and the fan power silicon oil clutch structure between transmitting, and is a kind of silicon oil filled fan clutch of can control throwing off rotating speed specifically.
Background technique
At present, the minimum speed after known silicon oil filled fan clutch is thrown off is at 200-300 rev/min.Owing to need cooling timely when motor car engine operation water temperature is too high, so this silicon oil filled fan clutch has satisfied not the usage requirement of automobile, often because the too high automobile that makes of engine water temperature can not go.
The model utility content
The purpose of the utility model is to above-mentioned deficiency, and a kind of simple in structure, the accurate silicon oil filled fan clutch that can control the disengagement rotating speed of control is provided.
The technological scheme that realizes the utility model purpose is:
This silicon oil filled fan clutch that can control the disengagement rotating speed comprises driving shaft, is fixedly connected on active plate, housing, protecgulum on the driving shaft; Follower plate on the protecgulum, the silicone oil oil outlet on the follower plate, the active chamber between the shoe cream room between follower plate and the protecgulum, follower plate and the housing; Valve block, characteristics are on the cylindrical of active plate, to be fixedly connected with to contain oil projecting ring, have at least 2 oil resistance grooves on the oil projecting ring containing.
The utility model is simple in structure, reasonable in design, does not change the basic structure of existing silicon oil filled fan clutch, implements easily.
Silicon oil filled fan clutch is thrown off the minimum speed of back operation, depends primarily on active chamber and (also claims: remaining silicone oil amount torque chamber).Because the utility model is designed with and contains oil projecting ring, and have several oil resistance grooves on the oil projecting ring containing on the active plate cylindrical, can guarantee when silicon oil filled fan clutch is thrown off, in active chamber, still remain with and keep the required silicone oil of minimum speed.Be about to silicone oil and be retained on the gap of excircle and housing that active plate contains oil projecting ring, and under the effect of oil resistance groove, on-stream always being clipped between housing and the active plate cylindrical of these silicone oil do not reduced.And can contain the width of oil projecting ring through adjusting, parameters such as the quantity of oil resistance groove, angle of inclination enlarge or reduce the oil area of active plate, thereby reach the purpose that effective solenoidoperated cluthes are thrown off rotating speed.
Have simple in structure, control advantage such as accurate, can effectively control minimum speed after silicon oil filled fan clutch is thrown off between 500-750 rev/min, be adapted at promoting the use of on the truck, have bigger practical and popularizing value.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation.
Fig. 2 is the structural representation of active plate part among Fig. 1.
Fig. 3 is the left TV structure schematic representation of Fig. 2.
Among the figure: 1 driving shaft, 2 active plates, 3 housings, 4 protecgulums, 5 follower plates, 6 silicone oil oil outlets, 7 shoe cream rooms, 8 active chambers, 9 bimetal temp-sensitive apparatuss, 10 valve blocks, 11 contain oil projecting ring, 12 oil resistance grooves.
Embodiment
The utility model is further described with the embodiment who provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this silicon oil filled fan clutch of can control throwing off rotating speed is by the driving shaft 1 that can be connected with motor, be fixedly connected on the active plate 2 on the driving shaft; The housing 3 that can be fixedly connected with fan is formed with protecgulum 4.The protecgulum internal fixation has follower plate 5, follower plate to be provided with silicone oil oil outlet 6, and the cavity between follower plate and the protecgulum is a shoe cream room 7, and silicone oil is housed in it, and the cavity between follower plate and the housing is an active chamber 8.On protecgulum, be provided with bimetal temp-sensitive apparatus 9, the valve block 10 in the bimetal temp-sensitive apparatus control shoe cream room opens or closes the silicone oil oil outlet.On the cylindrical of active plate, be fixedly connected with and contain oil projecting ring 11, have several oil resistance grooves 12 on the oil projecting ring containing.
The utility model claimant is by embodiment; Implement this silicon oil filled fan clutch that can control the disengagement rotating speed, shown in accompanying drawing, during the processing active plate; On the cylindrical of active plate, directly process the oil projecting ring that contains, and have 6 oil resistance grooves that are left hand direction on the oil projecting ring containing with certain width.Through inner on probation the demonstration; When the gap of active plate and housing during at 0.3-0.5; Change the width that contains oil projecting ring; Can enlarge or reduce the oil area of active plate, effectively control the silicone oil amount between housing and the active plate, thereby reach minimum speed after the control silicon oil filled fan clutch is thrown off 500-750 rev/min technical requirements.After silicon oil filled fan clutch was thrown off, low commentaries on classics was no less than 500 rev/mins, satisfies the use of automobile; The high commentaries on classics is not higher than 750 rev/mins, and the silicon oil filled fan clutch frictional heat is not high.Fully guaranteed the usability requirement of truck silicon oil filled fan clutch.
