Abstract
The IC. engine cooling fan that marmem controls, constructs and is made up of fan shaft, shape memory alloy spring, backspring, driving disc, magnetic conductive disk, fan hub, magnet, driven disc, fan axle and bearing.Working principle: when the gas flow temperature after heat radiator of internal-combustion engine is lower than setting temperature, shape memory alloy spring is in contraction state, backspring makes magnetic conductive disk be in left position, magnet, forms magnetic loop between magnetic conductive disk and protecgulum.Between driven disc magnetic conduction ring gear and driving disc magnetic inductive block, magnetic force is very little; The rotating speed of fan is low.When the gas flow temperature after heat radiator of internal-combustion engine is higher than setting temperature, shape memory alloy spring is upheld gradually, and compression backspring, makes magnetic conductive disk move to right; Between driven disc magnetic conduction ring gear and driving disc magnetic inductive block, fan hub magnetic inductive block, magnetic force increases gradually, and the rotating speed of fan raises gradually, air quantity strengthens; Thus reach the object automatically changing air quantity of fan according to internal-combustion engine cooling requirements.
Description
Technical field
The utility model belongs to vapour and rubs and accessory technical field.
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.Therefore, many internal-combustion engines adopt the fan that silicon oil clutch is housed, and by the viscosity transferring power of silicone oil, control the rotating speed of fan, reduce the power that fan consumes, save fuel oil.But this fan clutch complex structure, causes fan cisco unity malfunction when silicone oil leaks.
Model utility content
The purpose of this utility model is to provide one magnetic force transferring power, controls magnetic conductive disk position by shape memory alloy spring, changes magnetic line of force trend; And then the magnetic force size between the master and slave Moving plate of controlling combustion engine fan, and then control air quantity of fan; Its reliability and energy-saving effect are better than silicon oil clutch fan.
Structure of the present utility model is made up of fan shaft, shape memory alloy spring, backspring, spring shaft, driving disc, magnetic conductive disk, fan hub, fan hub magnetic conductive disk, protecgulum, magnet, driven disc, fan shaft and bearing.Wherein, fan hub permeability magnetic material is made, and is loaded on fan shaft by bearing, fixing driven disc and fan hub magnetic conductive disk on it.Fan hub magnetic conductive disk non-magnet material is made, and embedded fan hub magnetic inductive block, is fixed in fan hub.Driven disc is disc, makes with non-magnet material, and embedded right side is shaped with the driven disc magnetic conduction ring gear of tooth.Driving disc is disc, makes with non-magnet material, and embedded driving disc magnetic inductive block, driving disc is fixed on fan shaft by spline.Protecgulum is drum-shaped, makes with permeability magnetic material, is fixed on fan hub; Magnet is annulus or watt shape, and radial magnetizing, is fixed on protecgulum.Magnetic conductive disk is disc, is positioned at protecgulum, and can at protecgulum, slide between magnet and driven disc magnetic conduction ring gear.One end of spring shaft is fixed on driven disc, and the other end inserts in the hole of protecgulum; Shape memory alloy spring and backspring are enclosed within spring shaft, for temperature-sensitive and promote magnetic conductive disk slide; Shape memory alloy spring and backspring are placed in the both sides of magnetic conductive disk respectively.
Working principle: when the gas flow temperature after heat radiator of internal-combustion engine is lower than setting temperature, shape memory alloy spring is in contraction state, backspring makes magnetic conductive disk be in left position, magnet, forms magnetic loop between magnetic conductive disk and protecgulum.Between driven disc magnetic conduction ring gear and driving disc magnetic inductive block and fan hub magnetic inductive block, the magnetic line of force is little, and magnetic force is very little; Therefore, when driving disc rotates with fan shaft; The rotating speed of fan is low, air quantity is little.When the gas flow temperature after heat radiator of internal-combustion engine is higher than setting temperature, shape memory alloy spring is upheld gradually, compression backspring; Magnetic conductive disk is moved to right gradually, and in magnet, magnetic conductive disk, driven disc magnetic conduction ring gear, driving disc magnetic inductive block, the magnetic loop that forms between fan hub magnetic inductive block and fan hub, the magnetic line of force increases gradually; Between driven disc magnetic conduction ring gear and driving disc magnetic inductive block, fan hub magnetic inductive block, magnetic force increases gradually; The rotating speed of fan raises gradually, air quantity strengthens.Thus reach the object automatically changing air quantity of fan according to internal-combustion engine cooling requirements.Because magnet, magnetic conductive disk, driven disc magnetic conduction ring gear, driving disc magnetic inductive block, the air gap that formed between fan hub magnetic inductive block and fan hub are very little, the moment of torsion that available few magnet transmission is large, decreases the consumption of magnet; And power needed for promotion magnetic conductive disk is less, can control with less shape memory alloy spring, low cost of manufacture.
