Description
Technical field
The present invention relates to a kind of engine-cooling system, specifically relate to a kind of silicon oil filled fan clutch assembly that is applied to car engine cooling system.
Background technique
At present, the silicon oil filled fan clutch assembly is as the important spare part of the engine-cooling system on the automobile, and to energy-conservation, reduction of discharging, the noise reduction of automobile, increasing service life of engine has played key effect.The electric-control silicone oil fan clutch assembly substitutes original temp-sensing silicon oil filled fan clutch assembly, it is by the circulation flow rate of automatically controlled silicone oil, the active part of control fan clutch assembly and the engagement of secondary part, disengaging response time, and utilize the tach signal of the Hall transducer Real-time Feedback fan in the sensing plate, electromagnetic valve component, realize the accurate control of closed loop, thereby make motor operation work under optimum temperature.The magnetic conducting plate of existing electric-control silicone oil fan clutch assembly (also claiming valve block) is contained on the protecgulum, a part that belongs to driven subassembly, form electromagnetic induction with electromagnetic valve component, the centrifugal force that it is subject to and oil return power are less, the circulation flow rate of automatically controlled silicone oil is slower, for the engagement of the active part of fan clutch assembly and secondary part, break away from the response time and will correspondingly prolong, thereby affected to a certain extent the optimum Working of motor.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of and can accelerate the circulation flow rate of automatically controlled silicone oil, the engagement of shortening its active part and secondary part, the efficient flow-guide electric-control silicone oil fan clutch assembly of disengaging response time.
Purpose of the present invention realizes by following technical solution: a kind of efficient flow-guide electric-control silicone oil fan clutch assembly, comprise driving shaft, housing, active plate, follower plate, protecgulum, at this housing fan is housed, at this driving shaft electromagnetic valve component is housed, on described active plate, and near magnetic conducting plate being housed the driving shaft place, on described active plate, and and follower plate between be provided with shoe cream room, in described protecgulum, be provided with the circulating oil path that communicates with this shoe cream room, between described housing and active plate, be provided with between protecgulum and the active plate and described shoe cream room, the active chamber that circulating oil path communicates.
After adopting the present invention, the electromagnetic induction of electromagnetic valve component and magnetic conducting plate and make the opening of magnetic conducting plate swing open shoe cream room, and make the silicone oil in the shoe cream room be back to shoe cream room again through active chamber, circulating oil path and form the mobile circulation loop of silicone oil; Because magnetic conducting plate is under the drive of active plate and driving shaft, the centrifugal force that is subject to and oil return power are larger, the circulation flow rate of silicone oil is accelerated, will correspondingly shorten for the active part of this fan clutch assembly and engagement, the disengaging response time of secondary part, control in real time the rotating speed of fan, thereby make all the time operation work under optimum temperature of motor, realize the target of vehicle energy saving, reduction of discharging, noise reduction.

Embodiment
The present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 1, shown in Figure 2, the present invention is applied to the efficient flow-guide electric-control silicone oil fan clutch assembly of car engine cooling system, comprise driving shaft 2, housing 6, active plate 7, follower plate 10, protecgulum 12, at this housing 6 fan 16 is housed, electromagnetic valve component 3 is equipped with in (and near its bearing 5 places) on this driving shaft 2, on described active plate 7, and near magnetic conducting plate 11 (also claiming valve block) being housed driving shaft 2 places, on described active plate 7, and and follower plate 10 between be provided with shoe cream room 9, (by the spill port 23 on it) is provided with the circulating oil path 17 that communicates with this shoe cream room 9 in described protecgulum 12, between described housing 6 and active plate 7, be provided with between protecgulum 12 and the active plate 7 and described shoe cream room 9, the active chamber 18 that circulating oil path 17 communicates.
Wherein, described electromagnetic valve component 3 comprises magnetism-guiding hood 24, electromagnetic coil 25, Hall transducer 26 etc., and it is electrically connected with the motor car engine microcomputer control system by wire harness assembly 1, between electromagnetic valve component 3 and driving shaft 2 magnetism resistent ring 4 is housed.On described active plate 7, and magnetic conduction grid 20 also are housed near the magnetic conducting plate place.Locate to be equipped with sensing plate 13 between housing 6 and electromagnetic valve component 3, be used for the rotating speed of induction housing and fan, its rotary speed data can in time feed back to the motor microcomputer control system.Because protecgulum is provided with circulating oil path from outside to inside, then steel ball 8 need to be set at the inner side edge of protecgulum, to block the outlet of circulating oil path outside protecgulum, prevents the leakage of silicone oil.A wherein end of described magnetic conducting plate 11 just joins with the oil outlet 27 of shoe cream room 9.
As shown in Figure 1, in order to shorten the electromagnetic induction distance between magnetic conducting plate and the electromagnetic valve component, to reduce quantity of magnetism loss, the center in described electromagnetic valve component 3 is equipped with concentrating flux plate 19, and this can directly carry out electromagnetic induction between magnetic conducting plate and concentrating flux plate.As shown in Figure 2, for make silicone oil in the described active chamber quicker, get back in the circulating oil path in the protecgulum more swimmingly, the angle of guiding into of the spill port 23 on the described protecgulum 12 is 20-30 degree (being spill port and horizontal angle α), to improve return pressure, accelerate the response time, the silicone oil in the active chamber enters circulating oil path in the protecgulum by this spill port.
As shown in Figure 3, in order to improve the velocity of liquid assets of fan center's air-flow, reduce running energy consumption and the noise of fan, be provided with fair water fin 21 in the root of blade front of described fan 16.As shown in Figure 4, in order to improve the structural strength of fan, prolong its working life, be provided with stiffening rib 22 at the root of blade back side of described fan 16.
Working principle of the present invention is: by the electromagnetic induction of electromagnetic valve component and magnetic conducting plate, make magnetic conducting plate open the oil outlet of shoe cream room in the active plate swing, and make the silicone oil in the shoe cream room be back to shoe cream room again and form the circulation loop that silicone oil flows through active chamber, circulating oil path successively.Because magnetic conducting plate is under the drive of active plate and driving shaft, the centrifugal force that is subject to and oil return power are larger, the circulation flow rate of silicone oil is accelerated, combination between housing, follower plate and the active plate is tightr, for the engagement of the active part (comprising driving shaft 2, active plate 7 etc.) of this fan clutch assembly and secondary part (comprising housing 6, fan 16, follower plate 10, protecgulum 12 etc.), break away from the response time and will correspondingly shorten, thereby in real time, accurately, fast control the rotating speed of fan.
