Abstract
The utility model provides an electromagnetic planet gear type internal combustion engine cooling fan clutch, which structurally consists of a fixing disc, an electromagnetic coil, an armature, a fan shaft, a bearing, a high-speed friction sheet, a middle-speed friction sheet, a planet carrier, a gear ring, a planet wheel, a sun wheel and fan blades. The electromagnetic planet gear type internal combustion engine cooling fan clutch has a work principle that when the temperature of internal combustion engine cooling liquid is low, smaller current passes through the electromagnetic coil; through the magnetic force of the electromagnetic coil, a press disc leaves the high-speed friction sheet, the gear ring, the planet wheel and the planet carrier freely rotate, and the fan blades operate at a low speed along with the planet carrier. When the temperature of the cooling liquid is higher, heavy current passes through the electromagnetic coil; the attraction force of the electromagnetic coil on the armature is increased, so the press disc is pressed on the middle-speed friction sheet, and the gear ring cannot rotate through the friction force between the press disc and the middle-speed friction sheet. Equivalently, the gear ring in a planet wheel system is fixed, the planet wheel and the planet carrier rotate along with the sun wheel, the transmission ratio is 1+Z2/Z1, and the fan blades operate at a middle speed along with the planet carrier. When the temperature of the cooling liquid is higher, the power of the electromagnetic coil is cut off, and the press disc is tightly pressed on the high-speed friction sheet through the elasticity of a disc-shaped spring, so the gear ring and the planet carrier are connected into a whole. In the planet wheel system, the gear ring, the planet wheel, the planet carrier and the sun wheel rotate at the same speed, and the fan blades rotate at a high speed along with the planet carrier.
Description
Technical field
The utility model relates to a kind of clutch of controlling combustion engine cooling fan.
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 electromagnetic 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.But this fan clutch complex structure because the magnetic force that adopts permanent magnet carrys out transferring power, can produce speed discrepancy between fan and fan shaft in the time of middling speed in the time of work; Not only can cause eddy current loss, also can produce a large amount of heat, cause fan efficiency and life-span to be reduced.
Model utility content
The purpose of this utility model is to provide a kind of electromagnetic planetary gear formula IC. engine cooling fan clutch, and this clutch is unified to control by a set of epicyclic train and formed with electromagnetic coil; Gear ring in electromagnetic force control epicyclic gear system after switching on by electromagnetic coil and the combination of planetary carrier and fixed tray with separate, realize and make fan obtain different speed; Thereby reach the object that automatically changes air quantity of fan according to engine radiating requirement.Compared with common three-speed electromagnetic clutch, when work fan and fan shaft between without speed discrepancy; Can not cause eddy current loss, energy-saving effect is better, simple in structure, reliability is higher.
Structure of the present utility model is made up of fixed tray, electromagnetic coil, armature, fan shaft, bearing, high-speed friction sheet, middling speed friction plate, planet carrier, gear ring, planet wheel, sun gear, flabellum.Wherein, fan shaft is made stepped shaft, and gear ring, planet carrier are loaded on fan shaft by spline by bearing, sun gear; Gear ring, planet wheel, sun gear are intermeshing, and planet wheel links together by planet wheel shaft and planet carrier.Fixed tray is disc, is fixed on internal-combustion engine, and middling speed friction plate is fixed in its right side; Electromagnetic coil shell is fixed on fixed tray.Gear ring is loaded on fan shaft by bearing, and gear ring left end is screwed belleville spring, the middle part stationary annular armature of belleville spring, and armature is corresponding with electromagnetic coil; The outer rim of belleville spring is also fixed an annular platen, and annular platen pine is enclosed within on gear ring.Planet carrier is loaded on fan shaft by bearing, and high-speed friction sheet is fixed in left side; In flabellum fixed carrier.
Working principle: when internal combustion engine, fan shaft rotates; In the time that the temperature of cooling liquid is low, electromagnetic coil passes to small electric stream; The magnetic attraction of electromagnetic coil is fixed on the armature on belleville spring, and armature drives belleville spring and the platen being fixed on belleville spring to swing left; Platen leaves high-speed friction sheet, zerofriction force between platen and high-speed friction sheet; Sun gear rotates with fan shaft, and gear ring, planet wheel, planet carrier freely rotate, and flabellum is with planet carrier low-speed running.In the time that coolant temperature is higher, electromagnetic coil passes to larger electric current; Electromagnetic coil strengthens the attraction force of armature, and armature drives belleville spring and is fixed on the further swing left of platen on belleville spring; Platen is pressed on middling speed friction plate, and the frictional force between platen and middling speed friction plate is not rotated gear ring.Be equivalent to planetary gear train gear ring and fix, planet wheel, planet carrier rotate with sun gear, and velocity ratio is 1+Z2/Z1 (Z2 is the gear ring number of teeth, the Z1 sun gear number of teeth), and flabellum turns round with planet carrier middling speed.In the time that coolant temperature is higher, electromagnetic coil power-off, the elastic force of belleville spring is pressed on platen on high-speed friction sheet, and the frictional force between platen and high-speed friction sheet can not be rotated gear ring and planet carrier mutually, is equivalent to make gear ring and planet carrier to be connected as a single entity.The synchronized rotation of gear ring, planet wheel, planet carrier and sun gear in planetary gear train, velocity ratio is 1; Flabellum runs up with planet carrier.Therefore,, in the time that fan shaft rotates, pass to different electric currents and power-off by electromagnetic coil; Can make fan obtain different speed; Thereby reach the object that requires automatically to change air quantity of fan according to heat radiation.Impact for making to reduce, electromagnetic coil electrical current should increase gradually.
