Description

Front end transmission gear train of transverse engine of automobile Technical Field The utility model belongs to the technical field of automobile engine structures, and particularly relates to a front end transmission gear train of an automobile transverse engine. Background For micro-surface/light passenger commercial vehicles, the mounted engine needs to be economical, low in maintenance cost and reliable, so that a transverse gasoline engine is generally selected. The front end drive train of the engine is a power core of engine auxiliary equipment, and has compact design, integrated functions and relatively simple maintenance. The front end transmission gear train transmits power of a crankshaft to a water pump wheel, a generator wheel and the like through a transmission belt, the water pump wheel drives cooling liquid to circulate, and the generator wheel drives the generator to generate power. The drive belt tensioner (i.e., tensioner) of the front drive train is a critical component that ensures that the drive belt (e.g., V-ribbed or toothed belt) maintains proper tension and that prevents slippage, vibration or premature wear of the belt by adjusting the belt's tightness.
