Embodiment 1

[0041] A modification of the connection structure between the eddy current disk 21 and the second bearing 4 in Embodiment 1 is that the thermal insulation material is not coated on the heat insulation area 21c of the eddy current disk 21 in Embodiment 1, and the heat insulation area 21c of the eddy current disk 21 is A ceramic heat insulating pad 31 is arranged between the left end face and the right end face of the fixing ring 41 .

[0042] like Figure 5 As shown, the heat insulating pad 31 is a circular ceramic thin plate, and the third connecting hole 32 corresponding to the first connecting hole 26 is provided on the thin plate. A groove 33 pointing to the center is provided on the left and right end faces of the thin plate. The groove 33 can reduce the area of ​​the contact surface, utilize the negative pressure formed by the rotation of the heat sink when the eddy current disk 21 rotates, and extract the heat on the outer circle of the second bearing 4 along with the a...

Abstract

A low-carbon economical electromagnetic fan clutch comprises a main shaft and a fan fixing disc. The low-carbon economical electromagnetic fan clutch is characterized by further comprising an electric eddy current disc; the fan fixing disc and the electric eddy current disc are sequentially arranged from left to right in the axial direction from the left end of the main shaft; one or more permanent magnets surrounding the main shaft are arranged on the fan fixing disc; a conductive non-magnetic material is fixed to the position corresponding to the electric eddy current disc; the fan fixing disc is rotatably connected with the main shaft through a first bearing, and the electric eddy current disc is rotatably connected with the main shaft through a second bearing. According to the low-carbon economical electromagnetic fan clutch, an electromagnetic eddy current high heat accumulation area is effectively separated from the fan fixing disc which rotates at a high speed, energy consumption and materials used for manufacturing the low-carbon economical electromagnetic fan clutch have great advantages compared with a traditional model, and the effects of being economical and environmentally friendly are achieved.

Description

[0001] This application is a divisional application of a Chinese application with an application date of March 27, 2013 and an application number of 201310103135.6 entitled "Low-Carbon Economical Electromagnetic Fan Clutch". technical field [0002] The invention relates to a fan clutch, in particular to an electromagnetic fan clutch. Background technique [0003] The electromagnetic fan clutch is widely used in the field of vehicle engine heat dissipation. Among them, the variable speed electromagnetic fan clutch with flexible connection has the characteristics of timely temperature response and small impact force when the working state changes. The flexible connection structure it adopts is mainly based on the principle of magnetic field traction or eddy current magnetic field traction, which is generated by the relative motion of a soft iron disc and a permanent magnet. [0004] However, during the flexible connection process of the electromagnetic fan clutch, due to the ...
