Abstract
The utility model belongs to the technical field of automobile engine cooling, particularly relates to an electromagnetic silicon oil clutch of a fan, comprising a driving shaft, an active plate, a shell and silicon oil; the middle of the shell is arranged on the driving shaft by a bearing; the active plate is fixed at one end of the driving shaft and positioned inside the shell; a tooth socket matching structure is arranged inside a working cavity formed between the active plate and the end surface of the shell; the other end of the driving shaft is provided with a terminal pad; the active plate is provided with a spring valve sheet and an oil inlet hole which are opened and closed in a matching way; an oil storage cavity is formed by the cavity which is formed by boundary abutted surfaces of an oil cavity cover with the active plate and with the shell; the shell at the right side is further provided with an oil return hole communicating the working cavity with the oil storage cavity; and the clutch is characterized by arranging the bearing on the driving shaft so as to support and connect with an iron core with an electromagnetic coil and arranging a soft iron panel at the corresponding position of a spring strip. The clutch has the advantages of simple structure, accurate temperature control, stable running and long service life.
Description
Technical field: the utility model belongs to the Auto Engine Cooling System technical field, is specifically related to a kind of electromagnetic silicone oil fan clutch.
Background technique: along with being extensive use of of power-saving technology, also more and more higher to the energy-conservation requirement of motor car engine, and fan is the consumer of motor, be about 10% of engine power when maximum, in order to reduce the consumption of fan power, reduce noise and wearing and tearing, prevent that motor is cold excessively, reduce and pollute, fuel saving adopts fan clutch to be controlled the running of fan more, and is mostly to adopt valve block and oilhole fit form in the design of its oil circuit of silicon oil filled fan clutch that uses at present, its working principle: a kind of is to utilize two thermal sensitive piece temperature-sensitives, drive main axis rotation, make valve block rotate away from oil inlet hole oiling in active chamber, driving fan turns round with live axle, otherwise the valve block revolution is with the oil inlet hole sealing, and it exists temperature-sensitive inaccurate, operation is unstable insensitive, the defective that life-span is short; Another kind is to establish electromagnetic coil on hull outside, the attraction force that the magnetic field that produces when utilizing the electromagnetic coil energising produces valve block, oil inlet hole is opened, oiling in active chamber, the drive fan turns round with live axle, and its shortcoming is that complex structure, housing seal are poor, and when electromagnetic coil short of electricity or damage, oil inlet hole always is in closed condition, easily causes the motor phenomenon of boiling, and influences the working life of motor.
The model utility content
The purpose of this utility model provides a kind of simple in structure, effective, production and assembly are easy, stable, the life-span is long a kind of electromagnetic silicone oil fan clutch.
The technical solution of the utility model is: a kind of electromagnetic silicone oil fan clutch comprises live axle, active plate, housing and silicone oil; In the middle of the housing by Bearing Installation on live axle; Active plate is fixed on live axle one end and is positioned at housing, is provided with the teeth groove cooperating structure in the active chamber that constitutes between active plate and the housing end face; Establish land on the live axle the other end, active plate is provided with and opens and closes spring valve plate and the oil inlet hole that cooperates; The oil pocket lid reaches the cavity of forming with housing boundary faying surface with active plate and constitutes oil storage chamber; On the housing of right side, also be provided with the spill port that is communicated with active chamber and store oil cavity; It is characterized in that: on live axle, establish the iron core of bearings connecting band electromagnetic coil, on the spring sheet corresponding position, establish the soft iron plate.
Owing to adopt technique scheme, it is to utilize electromagnetic coil energising back to produce magnetic field the attraction force of spring valve plate is closed oil inlet hole; Otherwise, oil inlet hole is opened, control the running of fan, thereby have advantage simple in structure, that temperature control is accurate, stable, life-span is long.
Description of drawings: come the technical solution of the utility model is elaborated below in conjunction with the drawings and specific embodiments.Accompanying drawing is a structural representation of the present utility model.
Embodiment: with reference to the accompanying drawings, a kind of electromagnetic silicone oil fan clutch comprises live axle 1, active plate 2, housing 3 and silicone oil; In the middle of the housing 3 by Bearing Installation on live axle 1; Active plate 2 is fixed on live axle one end and is positioned at housing, and 5 are provided with the teeth groove cooperating structure in the active chamber that constitutes between active plate 2 and housing 3 end faces; Establish land 4 on live axle 1 the other end, active plate 2 is provided with and opens and closes spring valve plate 6 and the oil inlet hole 9 that cooperates; Oil pocket lid 7 reaches the cavity of forming with housing 3 boundary faying surfaces with active plate 2 and constitutes oil storage chamber 8; On the housing of right side, also be provided with the spill port 11 that is communicated with active chamber 5 and store oil cavity 8; It is characterized in that: on live axle 1, establish the iron core 10 of bearings connecting band electromagnetic coil, on spring sheet 6 corresponding positions, establish soft iron plate 12.
During use, be directly installed on the water pump pulley by land, opening and closing by electromagnetic coil power on/off control spring valve block and oil inlet hole, when being in opening state, the electromagnetic coil outage, engine temperature is higher, silicone oil in the oil storage chamber is entered in the active chamber by oil inlet hole, active plate utilizes the toughness of silicone oil to drive housing and fan rotates, fan clutch is in jointing state, for not making the silicone oil oil temperature in the active chamber too high, cause viscosity to descend, make silicone oil constantly circulation in active chamber and oil storage chamber, the silicone oil in the active chamber gets rid of to the active chamber outer rim from active plate under centrifugal action, and flowing to oil storage chamber by spill port, the silicone oil of oil storage chamber in time replenishes fluid to active chamber through oil inlet hole again; When being in closed condition, the electromagnetic coil energising, engine temperature is lower, and silicone oil flows back to oil storage chamber from spill port in the active chamber, and till getting rid of sky, fan clutch is in separated state.
