Abstract

An angle actuating mechanism on the cooling fan of the automobile engine belongs to the side engine cooling device. The fan unit assemblage 4 connects with its belt pulley unit assemblage 3. The fan belt pulley 18 on its belt pulley unit assemblage 3 links the actuating belt pulley 17 on the angle actuating mechanism unit assemblage of the belt pulley 1. A power belt pulley 5 is set against to the actuating belt pulley 17. It has low required precision on the installation site, convenient arrangement and assemblage of the engine and the crank pulley. The belt driving is adopted between the angle actuating mechanism unit assemblage of the belt pulley 1 and the fan belt pulley unit assemblage 3, which has simple structure, good vibration resistance, low noise, convenient installation and maintenance, stable and reliable actuating performance. The transmission speed ratio can be adjusted by changing the size of the external diameter of the belt pulley, which has good versatility.

Description

technical field [0001] The invention relates to an air cooling device for an automobile engine, in particular to a side-mounted automobile engine cooling fan angle transmission mechanism. Background technique [0002] At present, in the fan cooling system driven by the fan belt transmission mechanism used in the existing rear engine vehicles, the fan shaft of the radiator must be parallel to the crankshaft of the engine, that is, the engine and the radiator should be arranged side by side, and at the same time, an air vent should be opened on the side of the vehicle body to seal Into the air duct. With the popularization of passenger cars equipped with high-power engines, the heat dissipation of the water jacket also increases accordingly, so the requirements for the heat dissipation area of ​​the radiator and the diameter of the fan of the cooling system also increase correspondingly, but it is limited by the width of the vehicle and the height of the floor , if the fan sh...
