Abstract
The utility model provides a novel electromagnetism car fan clutch which the structure comprises an axle, initiative dish, driven plate, coil shell, coil, flabellum and bearing. The theory of operation: the internal -combustion engine drives the fan axle and rotates with the initiative dish, when the temperature of coolant liquid was less than the settlement temperature, control switch was in open position, the coil cold, and the coil does not have the magnetic line of force, there are not magnetic force, fan low -speed operation between driven plate and the initiative dish. When coolant temperature reached the settlement temperature, control switch was closed, the coil produces magnetic field, initiatively coil the magnetic force that magnetically gear ring, magnetic conduction piece and driven plate magnetic conduction piece air gap department produced the inter attraction, the power of initiative dish passes to on the driven plate through magnetic force, the work of drive fan. The driven plate rotational speed was less than and initiatively coiled the rotational speed this moment. Along with the temperature risees, the electric current in the coil is crescent, makes the appeal grow gradually between initiative dish and the driven plate, and the driven plate rotational speed edges closer to and initiatively coils the rotational speed, final initiative dish rotates with the driven plate is synchronous, no longer throws off.
Description
Technical field
The utility model relates to a kind of electromagnet automobile fan clutch.
Background technique
Internal-combustion engine is the radiating effect strengthening radiator, all fan is 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 the combination that the electromagnetic force by coil controls friction plate realizes transmission of power and interruption with being separated, and then controls the rotating speed of fan, to reduce power, saving fuel oil that fan consumes.This fan clutch complex structure, particularly drive plate must process a few and hate narrow magnet isolation tank, manufacture difficulty; And coil is placed in drive plate, assembly precision requires high, weak heat-dissipating.Owing to realizing by friction combining and being separated, reliability is low.
Model utility content
The purpose of this utility model is to provide a kind of electromagnet automobile fan clutch.This clutch forms primarily of fan shaft, driving disc, driven disc, coil and coil case.Magnetic force after dependence coil electricity between driven disc and driving disc, realizes driven disc is rotated with driving disc; Thus drive fan work.Compared with ordinary electromagnetic clutch, operationally nothing friction between driven disc, driving disc, reliability is high; By the size of electric current in control coil, the magnetic force between driven disc and driving disc can be changed; Obtain required various rotating speeds easily.Adopt many air gaps, make electromagnetic efficiency higher.
Structure of the present utility model is made up of fan shaft, driving disc, driven disc, coil case, coil, flabellum and bearing.Wherein, driven shaft makes stepped shaft, for installing driving disc, driven disc and coil case; Driving disc is disc, manufactures with non-magnet material; It is embedded with inside and outside driving disc magnetic conduction ring gear and the equally distributed driving disc magnetic inductive block of a circle; Driving disc is contained on fan shaft by spline.Driven disc is ring, manufactures with non-magnet material; It is shaped with the driven disc magnetic inductive block that inside and outside two circles are identical with driving disc magnetic inductive block number; Outer driven disc magnetic inductive block strides across outer driving disc magnetic conduction ring gear and driving disc magnetic inductive block, and interior driven disc magnetic inductive block strides across interior driving disc magnetic conduction ring gear and driving disc magnetic inductive block; Form two pairs of air gaps.Driven disc is loaded on fan shaft by driven disc bearing.Coil case is ring, and inside and outside edge is shaped with the inner and outer annular limit of one fixed width, to increase magnetic conductive area; Coil case doubles as iron core, manufactures with permeability magnetic material; The inside and outside limit of coil case is relative with driving disc inside and outside driving disc magnetic conduction ring gear; And have certain gap.Coil case is loaded on fan shaft by bearing coil, and coil is placed in coil case.Flabellum is screwed on driven disc.
Working principle: internal-combustion engine drives fan shaft and driving disc rotate; When the temperature of cooling liquid is lower than setting temperature, control switch is in off position, coil no electric circuit, and coil is without the magnetic line of force; Without magnetic force between driven disc and driving disc, fan low-speed running.When coolant temperature reaches setting temperature, control switch closes; Coil produces magnetic field.The magnetic line of force is led ring gear → outer driven disc magnetic inductive block → driving disc magnetic inductive block → interior driven disc magnetic inductive block → interior driving disc by coil case → outer driving disc and is led ring gear → coil case formation closed-loop path.The magnetic force attracted each other is produced at driving disc magnetic conduction ring gear, magnetic inductive block and driven disc magnetic inductive block air gap place; The power of driving disc passes on driven disc by magnetic force; Drive fan works.Now driven disc rotating speed is lower than driving disc rotating speed.Along with temperature raises, the electric current in coil increases gradually, and make the attraction force between driving disc and driven disc become large gradually, driven disc rotating speed moves closer to driving disc rotating speed; Final driving disc and driven disc synchronous axial system, no longer throw off.
Because driving and driven part to link together transferring power by magnetic force by this clutch; Compared with friction clutcch, work more reliable.And the manufacture of master and slave Moving plate non-magnet material, leakage field is few; Make electromagnetic efficiency higher.And master and slave Moving plate need not open magnet isolation tank, it is easier to manufacture; Coil case exposes, good heat dissipation.
