Abstract

The invention relates to an electromagnetic fan driving device for a water tank of a rear-engine type large vehicle. The electromagnetic fan driving device comprises an electromagnetic clutch, a gear box and fan blades, wherein the electromagnetic clutch comprises a driving shaft, a belt wheel, a transmission disk and an iron core; the belt wheel is rotationally arranged at one end of the driving shaft; a large suction disk is fixedly arranged on one end surface of the belt wheel through an elastic sheet; the transmission disk is fixedly arranged on the driving shaft; one end surface of the transmission disk is adjacent to the large suction disk, and an iron core accommodating cavity is formed in the other end surface of the transmission disk; the iron core is rotationally arranged on the driving shaft or in the iron core accommodating cavity of the transmission disk, and is partially or entirely positioned in the iron core accommodating cavity; a first coil accommodating groove is formed in one end surface of the iron core; coils are arranged in the first coil accommodating groove; the first coil accommodating groove is in positional correspondence to the large suction disk; the other end of the driving shaft is connected with an input shaft of the gear box; an output shaft of the gear box is connected with a fan disk which is fixedly provided with the fan blades.

Description

technical field [0001] The invention relates to a device for cooling an automobile engine, in particular to a fan electromagnetic drive device for a large vehicle water tank with the engine rear mounted. Background technique [0002] At present, most buses have a rear engine, and the water tank of the engine is at the rear of the car. Compared with the front engine, this structure has the disadvantage that when the car is moving forward, the heat dissipation of the water tank is not good, and it is prone to high temperature boiling, which affects the normal operation of the engine. Work. [0003] In response to this problem, the applicant disclosed a three-speed reversing electromagnetic fan clutch, the publication number is CN101363358A, its structure is as follows figure 1 As shown, a belt pulley 1' is set at one end of the driving shaft 3' supported by the bearing seat on the base 2', and large and small electromagnetic coils covered with an iron core are set in the cavi...
