Abstract

The invention relates to a driving device for changing a fan rotating direction and a control method. An engine transmission wheel is connected with a fan driving wheel through a fan rotating direction change device; the fan rotating direction change direction includes a first driving wheel, a second driving wheel and a driven wheel; the fan driving wheel is connected with the driven wheel through a connecting piece; the fan driving wheel is connected with the first driving wheel through a first clutch; the first driving wheel and the second driving wheel are connected with the engine transmission wheel through connecting pieces; and the driven wheel is connected with the second driving wheel through a second clutch. The driving device for changing the fan rotating direction is simple in structure, convenient to control and low in production cost, changes the fan rotating direction through changing the working states of two clutches to realize the effect of changing the air flowing direction, achieves the purposes of engine heat dissipation and self-cleaning, reduces engine faults, and prolongs the engine life.

Description

technical field [0001] The invention belongs to the technical field of road and non-road vehicle cooling systems, and in particular relates to a driving device and a control method capable of changing the rotation direction of a fan. Background technique [0002] The heat dissipation of the existing engine cooling system is mainly to drive the cooling fan directly or indirectly through the engine crankshaft to take away heat. The blade angle of the fan is a certain value, and the fan can only be used for cooling the engine. However, for heavy machinery, due to the harsh operating environment, the vehicle will produce foreign debris during the work process, which will greatly reduce the working efficiency of the radiator. If there are too many impurities, the work has to be suspended to remove the impurities in the radiator, resulting in a waste of time. Therefore, changing the direction of the fan can not only meet the cooling requirements of the engine, but also reduce th...
