Abstract

The invention discloses a bus fan-belt transmission mechanism which comprises a crankshaft pulley, a crankshaft belt, a central pulley assembly, a fan belt, a fan pulley assembly and a triangular frame assembly. A central pulley of the central pulley assembly is a double-layer pulley. The crankshaft belt surrounds the crankshaft pulley and a layer of the central pulley. The fan belt surrounds the other layer of the central pulley and the fan belt pulley assembly. The triangular frame assembly comprises two inclined beams, a central pulley mounting support and a fan pulley mounting support. The central pulley mounting support is taken as a base edge to form a triangle frame of the triangular frame assembly with the two cant beams. The fan pulley mounting support is mounted in the center of the triangle frame. The fan pulley mounting support and the central pulley mounting support are mounted in the triangular frame assembly, so that assembly accuracy of the fan pulley mounting support and the central pulley mounting support on the triangular frame assembly is improved, and the fan belt can be well matched with two belt grooves. The bus fan-belt transmission mechanism is simple to assemble, and structure stability thereof is improved.

Description

technical field [0001] The invention relates to a rear cooling system fan belt transmission mechanism for a bus. Background technique [0002] With the development of rear engine bus technology, the fan belt transmission mechanism of the rear vehicle cooling system is also constantly improving. Common fan belt drive mechanism, the power source of the belt drive is the engine, the power is output from the crankshaft pulley of the engine and transmitted to the intermediate pulley through the crankshaft belt, and then transmitted to the fan pulley through the fan belt to drive the fan to rotate to the radiator for heat dissipation. The fan pulley and the intermediate pulley of the existing passenger car fan belt drive mechanism are installed separately, the flatness between the two is difficult to ensure, and the assembly accuracy is not enough, resulting in the fan belt not engaging well with the two belt grooves, and the assembly efficiency is low , the stability is not high...
