Problems solved by technology
However, for special vehicles, special vehicles have the need of wading or floating, the radiator air inlet cannot be arranged at the front cover, the radiator and fan must be arranged at a higher position above the water level, and the above fan is directly installed on the engine. The method on the crankshaft or water pump shaft is not suitable for special vehicles, and there are no air outlets on the sides and bottom of special vehicles, and the air flow resistance is large

The invention discloses a special vehicle fan transmission device. The special vehicle fan transmission device comprises a transmission shaft, a transmission flange, a drive arc-tooth bevel gear shaft, a driven arc-tooth bevel gear, a driven shaft, a half-coupling machine, first and second bearing bases, first, second, third and fourth conical bearings, a regulating gasket, a taper sleeve, first, second and third locking nuts, a supporting housing, a main housing and a bracket. Drive torque of a fan is transmitted to the fan through an engine crankshaft, the transmission shaft, the transmission flange, the drive arc-tooth bevel gear shaft, the driven arc-tooth bevel gear, the driven shaft and the half-coupling machine. The special vehicle fan transmission device is convenient to arrange, and capable of changing the mounting position of the fan, so that overall arrangement requirements of a special vehicle are met.
Description
technical field [0001] The invention relates to a special vehicle component, in particular to a special vehicle fan transmission device. Background technique [0002] Under normal circumstances, the air inlet of the car radiator is at the front cover, the radiator and the windshield are installed on the car body, and the fan is directly installed on the engine crankshaft or the water pump shaft. Viewed from the axial direction, the radiator is in front of the fan. In the front, the air flow resistance of this arrangement is small, and the cooling air volume increases with the increase of vehicle speed. However, for special vehicles, special vehicles have the need of wading or floating, the radiator air inlet cannot be arranged at the front cover, the radiator and fan must be arranged at a higher position above the water level, and the above fan is directly installed on the engine. The way on the crankshaft or the water pump shaft is not suitable for special vehicles, and th...
