Problems solved by technology

[0002] At present, most electromagnetic fan clutches are single-speed. Due to their single-speed operation, when the drive disc and the suction disc are engaged, the recoil force on the belt and the engine shaft is large, so it cannot meet the needs of high-power engine fans; there are also some Three-speed electromagnetic fan clutch, due to structural problems, the bearing of the fan fixed plate often fails, which greatly shortens the life of the clutch

Abstract

The invention belongs to the technical field of automotive cooling systems, and particularly relates to a three-speed electromagnetic fan clutch. The three-speed electromagnetic fan clutch is characterized in that a magnet fixing disc is arranged in a fan fixing disc cavity, the magnet fixing disc is connected with a main shaft through a bearing, and the magnet fixing disc is fixedly connected with a small attraction disc through a small elastic sheet. Therefore, the three-speed electromagnetic fan clutch has the advantages of simple structure, large attraction torque, small recoil force, highreliability and long service life.

Description

Technical field: [0001] The invention belongs to the technical field of automobile cooling systems, and in particular relates to a three-speed electromagnetic fan clutch. Background technique: [0002] At present, most electromagnetic fan clutches are single-speed. Due to their single-speed operation, when the drive disc and the suction disc are engaged, the recoil force on the belt and the engine shaft is large, so it cannot meet the needs of high-power engine fans; there are also some For the three-speed electromagnetic fan clutch, due to structural problems, the bearing of the fan fixed disk often fails, which greatly shortens the life of the clutch. Invention content: [0003] The purpose of the present invention is to provide a three-speed electromagnetic fan clutch with simple structure, large pull-in torque, small recoil force, high reliability and long service life. [0004] The technical scheme of the present invention is: a three-speed electromagnetic fan clutch...
