Abstract
The utility model relates to an axial air-gap combustion engine fan controlled by a wax-type temperature sensor. The axial air-gap combustion engine fan controlled by the wax-type temperature sensor comprises a fan shaft, a wax-type temperature sensor, a drive disc, a fan hub, a magnetic pole, a magnetic yoke disc, a driven disc, a magnetic induction disc, a fan shaft and a bearing. The wax-type temperature sensor plays a role of sensing temperature and controlling. Power is transmitted by magnetic force between the drive disc and the driven disc.
Description
Technical field
The utility model belongs to that vapour rubs and the accessory technical field.
Background technique
Internal-combustion engine all is equipped with fan for strengthening the radiating effect of radiator; Test shows that automobile needs the time of fan work less than 10% in the process of moving; Fan work does harm rather than good internal-combustion engine At All Other Times.The fan of silicon oil clutch is equipped with in current many internal-combustion engine employings, and by the viscosity transferring power of silicone oil, the rotating speed of control fan reduces power, saving fuel oil that fan consumes.But this fan clutch complex structure causes the fan cisco unity malfunction when silicone oil leaks.
The model utility content
The purpose of this utility model provides a kind of magnetic force transferring power of using, and by wax formula temp-sensitive apparatus temperature-sensitive and controlling magnet position, changes the magnetic force size, and then the IC. engine cooling fan of control air quantity; Its reliability and energy-saving effect are better than the silicon oil clutch fan.Because the air gap that forms between driving disc and the driven disc is very little, and forms a plurality of axial air-gaps, so available few big moment of torsion of magnet transmission; Reduce the consumption of magnet.
Structure of the present utility model is made up of fan shaft, wax formula temp-sensitive apparatus, backspring, driving disc, fan hub, magnetic pole, yoke dish, driven disc, magnetic induction dish, fan shaft and bearing.Wherein, fan hub is ring, is loaded on the fan shaft fan attachment hub magnetic conduction ring gear on it by bearing.Protecgulum is made with non-magnet material, in establish a magnetic shielding ring gear of being made by permeability magnetic material; Protecgulum is fixed together with bolt and fan hub.The yoke dish is made toothed disc, fixes a magnetic pole on each tooth; The yoke dish places in the protecgulum, and the tooth on the yoke dish places in the space between the magnetic shielding ring gear adjacent teeth, and the magnetic shielding ring gear endwisely slips relatively.Wax formula temp-sensitive apparatus is made up of wax formula temp-sensitive apparatus shell, push rod, paraffin and rubber sleeve; Wax formula temp-sensitive apparatus shell is fixed on the protecgulum center, and the push rod in the wax formula temp-sensitive apparatus withstands on the yoke dish; Be used for temperature-sensitive and promote the relative magnetic shielding ring gear with magnetic pole of yoke dish endwisely slipping.Backspring places between magnetic induction dish and the yoke dish, is used for making the yoke dish to be in position, a left side.Driving disc is disc, makes with non-magnet material, is contained on the fan shaft by spline; Be shaped on the driving disc magnetic inductive block that equates with the magnetic pole number on it.Driven disc is ring, makes with non-magnet material, is fixed on the fan hub; Be shaped on the driven disc magnetic inductive block that equates with the magnetic pole number on it.The magnetic induction dish is ring, makes with non-magnet material, is fixed on the protecgulum; Be shaped on the magnetic induction piece that equates with the magnetic pole number on it, the magnetic induction dish is used for avoiding magnetic pole to contact with driven disc when work, with the protection magnetic pole.
Working principle: when the gas flow temperature behind the heat radiator of internal-combustion engine was lower than setting temperature, the paraffin in the wax formula temp-sensitive apparatus was solid-state, and volume is little, and push rod is pushed in the rubber sleeve; Backspring promotes the magnetic induction dish and is in position, a left side, constitutes magnetic loop between magnetic pole and the magnetic shielding ring gear.By the magnetic line of force between the magnetic induction piece on the magnetic induction dish, driving disc magnetic inductive block and the driven magnetic inductive block seldom, magnetic force is very little; The rotating speed of fan is low.When the gas flow temperature behind the radiator was higher than setting temperature, paraffin melted liquefy gradually, and volumetric expansion forces rubber sleeve to shrink, and push rod is extrapolated, promotes the yoke dish and moves right; Make yoke dish and magnetic pole near the magnetic induction dish, make magnetic induction dish and driving disc magnetic inductive block, driven disc magnetic inductive block and yoke, magnetic pole form magnetic loop, it is big that the magnetic force between driving disc and driven disc and the magnetic induction piece becomes, and rotation speed of the fan increases; Heat radiation requires the purpose of change air quantity of fan automatically according to internal-combustion engine thereby reach.Because the air gap that forms between driving disc and the driven disc is very little, and forms a plurality of air gaps, therefore, available few big moment of torsion of magnet transmission.
