The invention provides an installation structure for a crankshaft and a crankshaft belt wheel. The installation structure comprises the crankshaft, a wheel hub connected with the crankshaft, the crankshaft belt wheel sleeving the wheel hub, and a shock absorption rubber gasket arranged between the wheel hub and the crankshaft belt wheel. The installation structure further comprises an acoustic panel assembly which is arranged on the side, away from the crankshaft, of the wheel hub. The installation structure for the crankshaft and the crankshaft belt wheel is provided with the acoustic panel assembly, the acoustic panel assembly is arranged on the side, away from the crankshaft, of the wheel hub, accordingly, vibration noise of the crankshaft can be well prevented from radiating to the front end of an engine through the sound insulation and noise reducing effect of the acoustic panel assembly, the possibility that loud noise radiates to the front end of the engine is greatly reduced, and the driving comfort of a vehicle is good.
Description
technical field [0001] The invention relates to the technical field of engine component installation structures, in particular to an installation structure for a crankshaft and a crankshaft pulley. Background technique [0002] The crankshaft pulley is a power transmission component that transmits the power of the engine to the front end of the engine, and drives other front-end accessories such as air compressors, generators, cooling fans, etc. through the belt. In the prior art, the connection structure between the crankshaft and the crankshaft pulley generally includes the crankshaft, the wheel hub and the crankshaft pulley sleeved on the wheel hub, wherein the wheel hub is connected to the crankshaft and can rotate around its axis with the crankshaft, and the crankshaft pulley can be connected to the crankshaft through a belt. The power transmitted from the hub is then transmitted to other front-end accessories. In order to reduce vibration, the connecting structure of ...
