Abstract
The utility model discloses an electromagnetic fan clutch with built-in friction drive. The electromagnetic fan clutch is mainly characterized in that a driving disc frame is fixedly connected with the end face of a bearing central loop of an inner cavity of a fan fixing plate, friction pieces are connected on the inner end face of the driving disc frame or/and the end face of the inner cavity of the fan fixing plate and are connected with the friction drive in a joint mode, and large friction torque generated in the process of working can drive blades which are large in size and heavy on the fan fixing plate to work in a set first-level differential from 1125r/m to 1200r/m. Rotating speed of working of the blades in the first-level differential is improved, time for conducting heat dissipation cooling to working water temperature of an engine by the first-level differential of blades is prolonged, times of repeated switching from the first-level differential to second-level high speed of the blades are reduced, and therefore power output and fuel consumption of the engine are reduced notably. A plurality of permanent magnets which are high in production cost in the prior art are replaced by the friction pieces which are low in production cost, and therefore manufacturing cost of products is reduced effectively.
Description
(1) technical field: the utility model relates to control electromagnetic fan clutch device; Be specifically related to a kind of electromagnetic fan clutch of built-in friction driving.
(2) background technique: control electromagnetic fan clutch device of the prior art, as Design of The Electromagnetic Fan-clutch, during work, iron-core coil gets electric generating an electromagnetic field, by adhesive dribbling moving magnet fixed tray in the drive plate adhesive, utilize the soft magnet that is provided with in described magnet fixed disc end face, the magnetic force that some block permanent magnets that in fan fixed disk, on resonator end surface, distribution is connected with relatively produce, the fan blade on the drive fan fixed tray is done the one-level differential and is rotated, and realizes the radiating and cooling to the engine operation water temperature.Its Shortcomings: the one, be subjected to the restriction of its structure due to described Design of The Electromagnetic Fan-clutch, the quantity of some block permanent magnets that in described fan fixed disk, on resonator end surface, distribution is connected with is also limited to thus, and the driving moment that the magneto drive fan fixed disk that produces in work is rotated is less.When drive fan fixed tray upper volume is large, when the fan blade of Heavy Weight rotates, rotating speed slippage significantly occurs, do not reach the one-level differential working speed requirement of setting.Actual speed after common described fan blade rotating speed slippage can only maintain in 600 rev/mins of-750 rev/mins of scopes, is the 40%-50% of 1500 rev/mins of motor output speeds.Because being in the lower rotating speed of one-level differential all the time, fan blade works, cause motor car engine work water temperature to can not get timely radiating and cooling, rise to quickly the high temperature setting value, drive Design of The Electromagnetic Fan-clutch by the temperature controlling device control engine prematurely, switch to secondary full speed at a high speed by the lower rotating speed of one-level differential and rotate, drives described fan fixed disk upper volume greatly, the fan blade of Heavy Weight carries out the high speed rotating radiating and cooling to the engine operation water temperature.When the engine operation water temperature was reduced to the high temperature setting value again, temperature controlling device control engine again drove Design of The Electromagnetic Fan-clutch, is converted to the lower rotary speed working of one-level differential by secondary high speed rotary speed working.Carry out continually thus the conversion repeatedly of I and II working speed.When the engine-driving electromagnetic fan clutch is converted to the full speed rotation work of secondary high speed by the lower rotating speed of one-level differential, increased significantly power stage and the fuel consume of motor.The 2nd, due to the some block permanent magnets that distribute and be connected with on resonator end surface in described fan fixed disk, cost of production is higher, has increased significantly the manufacture cost of product.
(3) summary of the invention: for the deficiency of above-mentioned prior art existence, the purpose of this utility model is to provide a kind of electromagnetic fan clutch of built-in friction driving, be intended to improve the rotating speed of fan blade one-level differential work, with the fuel consume of reduction motor and the manufacture cost of product.
