Problems solved by technology

[0003] In the automotive water pump or electromagnetic fan clutch in the prior art, its magnet structure includes an insert iron ring and a group of permanent magnets, wherein the permanent magnet is axially embedded on the insert iron ring, occupying a large amount of axial space; in addition, When assembling, it is necessary to embed the permanent magnets into the insert iron ring one by one. The assembly is cumbersome, and the permanent magnets may fall off when the clutch is running.

Abstract

The invention discloses an easy-to-assemble two-stage speed change clutch of an automobile cooling system. The clutch comprises a spindle penetrating through an outer support and a transmission wheel and a clutch device sleeving the end part of the outer support; a magnet structure is arranged in a hollow cavity formed by the inner annular surface of the transmission wheel and the spindle, wherein a magnetic pole of the magnet structure is arranged on the peripheral surface of the magnet structure, and the magnet structure comprises an annular magnet sleeving the spindle. Such design structure is compact and an axial distance of the clutch is reduced; a magnetic field directly acts on the inner annular surface of the transmission wheel, when the clutch device is powered off and disconnected, the magnet structure drives the spindle to rotate at a low speed, and when the clutch is powered on and connected, the spindle and the transmission wheel rotate synchronously to realize two-stage rotary speed output; one whole annular magnet replaces the embedding manner of small magnets, the falling possibility of the small magnets is avoided, the reliability is good, the step of embedding the small magnets is omitted and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an easy-to-assemble two-stage transmission clutch for an auto cooling system. Background technique [0002] The automobile cooling system is a system used to prevent the engine from overheating. The automobile water pump is an important part of the automobile engine cooling system. The engine drives the main shaft and impeller of the water pump to rotate through the pulley. The coolant in the water pump is driven by the impeller and under the action of centrifugal force. It is thrown to the edge of the water pump housing, then flows out from the water pipe, and reciprocates to cool the car engine; the radiator and radiator fan are also the main components of the car cooling system; the clutch is set on the main shaft of the water pump or radiator on, to control the operation of the water pump or radiator fan. [0003] In the automotive water pump or electromagnetic fan clutch...
