Abstract
The utility model discloses a novel electromagnetic cooling fan clutch of an internal combustion engine. The novel electromagnetic cooling fan clutch structurally consists of fixing frames, driven wheels, a driving disk, a fan shaft, bearings, coils and iron cores. The internal combustion engine drives the fan shaft and the driving disk to rotate; when the temperature of cooling liquid is lower than set temperature, the coils are not energized and do not have magnetic force lines; a magnetic force does not exist between the driven wheels and the driving disk, and a fan does not work. When the temperature of the cooling liquid is higher than the set temperature, the coils are energized; the magnetic force lines generated by the coils form a closed loop through the driven wheels, magnetic conduction teeth thereon, the driving disk, magnetic conduction teeth thereon and the iron cores. Moreover, a mutual attraction force is formed between the magnetic conduction teeth on the end surfaces of the driven wheels and the magnetic conduction teeth on the driving disk, enables the driven wheels to rotate along with the driving disk, and drives the fan to work.
Description
Technical field
The utility model relates to a kind of IC. engine cooling fan clutch of Electromagnetic Control.
Background technique
Internal-combustion engine is the radiating effect that strengthens radiator, and fan is all housed; Test shows, automobile needs the time of fan work less than 10% in the process of moving; Fan work combustion motor does harm rather than good At All Other Times.Many internal-combustion engines adopt the three fast fans that magnetic clutch is housed, and by the combination of the electromagnetic force control friction plate of coil with separates to realize transmission of power and interruption, and then control the rotating speed of fan, reduce power, the saving fuel oil of fan consumption.Not only complex structure of this fan clutch, and owing to realizing combination and separating by friction, reliability is low.
Model utility content
The purpose of this utility model is to provide a kind of novel electromagnetic IC. engine cooling fan clutch, and this clutch is mainly made up of fan shaft, driving disc, follower, coil and iron core.One end of follower and driving disc is shaped with magnetic teeth, and the magnetic force between coil electricity back front driven wheel and driving disc magnetic teeth makes combining of follower and driving disc, realizes follower is rotated with driving disc; Thereby drive fan is rotated.Compared with common magnetic clutch, nothing friction between follower, driving disc in the time of work, reliability is higher; And without friction plate and return spring, make structure simpler.
Structure of the present utility model is mainly made up of fixing frame, follower, driving disc, fan shaft, bearing, coil, coil brace and iron core.Follower is wherein made up of wheel hub, spoke and wheel rim, and fan is fixed on follower; Between wheel hub and wheel rim, form annular space, it is discontinuous that spoke has two circles, plays the groove of separated magnetic effect; On follower end face, be shaped with a few magnetic teeth, fixing frame is screwed in internal combustion (IC) engine airframe, and follower is loaded on fixing frame by bearing.Coil and iron core are placed in follower annular space, and between follower, leave certain interval; And be fixed on fixing frame by coil brace.Driving disc is disc, is contained on fan shaft by spline, is shaped with a few magnetic teeth on it, corresponding with the magnetic teeth on follower respectively.
Working principle: internal-combustion engine drives fan shaft and driving disc rotate; When the temperature of cooling liquid is during lower than setting temperature, coil no electric circuit, coil is without the magnetic line of force; Between follower and driving disc, without magnetic force, fan is not worked.When coolant temperature is during higher than setting temperature, coil electricity; The magnetic line of force that coil produces by follower and on magnetic teeth, driving disc and on magnetic teeth and iron core form closed-loop path.And between the magnetic teeth on magnetic teeth and driving disc on follower end face, form mutual attraction force, this attraction force makes follower rotate with driving disc, drive fan work.By the electric current of regulating winding, the attraction force between the magnetic teeth on adjustable main Moving plate and follower, thereby the rotating speed of adjusting fan; Make it to adapt to the heat radiation requirement of internal-combustion engine.
Brief description of the drawings: accompanying drawing is tectonic maps of the present invention, (1) coil, (2) coil brace, (3) bearing, (4) fan shaft, (5) fixing frame, (6) iron core, (7) follower, (8) magnetic teeth, (9) magnet isolation tank, (10) driving disc, (11) nut, (12) spline, (13) snap ring, (14) fan in figure.
Embodiment
It is upper that driving disc in accompanying drawing (10) is loaded on fan shaft (4) by spline (12), and follower (7) is loaded on fixing frame (5) by bearing (3); Coil (1) is loaded on fixing frame (5) by coil brace (2).
Claims (2)
1. a novel electromagnetic IC. engine cooling fan clutch, is characterized in that: the structure of novel electromagnetic IC. engine cooling fan clutch is made up of fixing frame, follower, driving disc, fan shaft, bearing, coil, coil brace and iron core; Follower is wherein made up of wheel hub, spoke and wheel rim, between wheel hub and wheel rim, forms annular space, and it is discontinuous that spoke has two circles, plays the groove of separated magnetic effect; On follower end face, be shaped with a few magnetic teeth, follower is loaded on fixing frame by bearing; Coil and iron core are placed in follower annular space, and between follower, leave certain interval; And be fixed on fixing frame by coil brace.
