Abstract
A magnetic fan clutch is composed of a fan shaft, a shape memory alloy spring, a drive disc, a reversal spring, a fan hub, magnetic poles and a bearing. The shape memory alloy spring is used for measuring temperature and control. The fan hub is mounted on the fan shaft through the bearing, the fan hub is bonded with magnetic poles, when the gas flow temperature after heat radiation of engine is lower than the preset temperature, the shape memory alloy spring is in compression state and the magnetic disc is positioned at right side due to the reversal spring so that the magnetic poles are separated from the drive disc; the magnetic disc and the fan hub magnetic poles form a magnetic loop. The magnetic force between the drive disc and the fan hub magnetic poles is small, the rotating speed of fan is low and the air volume is small. When temperature is higher than the preset temperature, the shape memory alloy spring is in stretching state, the reversal spring is compressed to drive the magnetic disc and the guide shaft to move leftwards so that the magnetic loop is formed between the drive disc and the fan hub magnetic poles so that the magnetic force between the drive disc and the fan hub magnetic poles is great, the rotating speed of fan is increased and the air volume is increased.
Description
Technical field
The utility model belongs to technical field of internal combustion engines.
Background technique
Internal-combustion engine all is equipped with fan for strengthening the radiating effect of radiator; 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.Many for this reason internal-combustion engines adopt the fan that silicon oil clutch is housed, 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 is: provide a kind of magnetic force transferring power of using, by the clutch of moment size between shape memory alloy spring control driving disc and the fan hub magnetic pole; Its reliability and energy-saving effect are better than silicon oil clutch.
Structure of the present utility model is made up of fan shaft, shape memory alloy spring, driving disc, backspring, fan hub, magnetic pole, bearing etc.Wherein shape memory alloy spring is enclosed within on the axis of guide, and the position of an end is limited by nut, and the other end withstands on the support; Be used for temperature-sensitive and control.Backspring is between magnetic conductive disk and support.Fan hub is loaded on the fan shaft by bearing, and fan hub circumferentially coheres some to magnetic pole; And be shaped on and the corresponding tooth of magnetic pole.Fan is fixed on the fan hub, and driving disc is a disc, is fixed on the fan shaft, and end face is shaped on the tooth that equates with fan hub magnetic pole number.Magnetic conductive disk is a disc, is shaped on flabellum on it, is used for loosing when removing magnetic pole and driving disc relative movement because the heat that electric convolution produces.Support is fixed on the fan hub, and the centre is shaped on pilot hole; The axis of guide is fixed on the magnetic conductive disk, and passes the pilot hole on the support.
Working principle: when the gas flow temperature behind the engine radiator was lower than setting temperature, shape memory alloy spring was in contraction state, and backspring makes magnetic conductive disk be in right position, and magnetic pole and driving disc tooth are separated; Magnetic conductive disk and fan hub magnetic pole form magnetic loop.Magnetic force between driving disc and the fan hub magnetic pole is very little; The rotating speed of fan is low, air quantity is little.When temperature is higher than setting temperature, shape memory alloy spring is upheld, and magnetic conductive disk is moved to the left with the axis of guide, forms magnetic loop between driving disc tooth and fan hub magnetic pole and the fan hub tooth, it is big that magnetic force between driving disc and fan hub magnetic pole and the tooth becomes, and rotation speed of the fan height, air quantity are big; And reach the purpose that changes air quantity of fan according to the engine radiating requirement automatically.The utility model is because by magnetic drives, no friction and wear, and its reliability is very high.And form two air gaps between driving disc tooth and magnetic pole and the fan hub tooth, the magnetic torque that the magnetic torque that identical magnet produces produces during than single air gap is twice.
Description of drawings: accompanying drawing is the tectonic maps of model utility, (1) magnetic conductive disk, (2) support, (3) stop pin (4) axis of guide, (5) marmem bullet, (6) backspring, (7) flabellum, (8) fan, (9) fan hub, (10) retaining ring, (11) driving disc, (12) bearing (13) fan shaft, (14) fan hub tooth, (15) vent hole (16) driving disc tooth, (17) magnetic pole among the figure.
