Problems solved by technology

[0006] The purpose of the present invention is to provide a low-carbon economical electromagnetic fan clutch, which solves the technical problem that the heat generated by the electromagnetic eddy current causes the connecting bearing of the fan fixed disk and the connecting fan blade structure to be easily damaged when the electromagnetic fan clutch is flexibly connected.

Embodiment 1

[0040] 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 .

[0041] 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 economic electromagnetic fan clutch comprises a spindle and a fan fixing disc and is characterized by further comprising an eddy current disc located at the left end of the spindle, wherein the fan fixing disc and the eddy current disc are sequentially arranged along the axial direction from left to right. A group of or a plurality groups of permanent magnets are arranged on the fan fixing disc and surround the spindle, and a conducting non-magnetic-conducting material is fixed at the corresponding position of the eddy current disc. The fan fixing disc is in rotary connection with the spindle through a first bearing, the eddy current disc is in rotary connection with the spindle through a second bearing. An electromagnetic eddy current high heat accumulation region and the high-speed rotating fan fixing disc are effectively separated. Compared with traditional types of fan clutches, energy consumption and a material for manufacturing the low-carbon economic electromagnetic fan clutch can have large superiority, and the economic and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to a fan clutch, in particular to an electromagnetic fan clutch. Background technique [0002] 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 plate and a permanent magnet. [0003] However, during the flexible connection process of the electromagnetic fan clutch, due to the unavoidable thermal effect in the electromagnetic conversion process, a large amount of heat will be generated, which has a great impact on the stability and service life of the electromagnetic fan clutch working in a harsh en...
