混合发动机的驱动皮带系统
摘要：
一种混合发动机的驱动皮带系统，可以包括：曲轴滑轮，曲轴滑轮可以布置为由发动机进行旋转；混合启动器发电机(HSG)滑轮，混合启动器发电机滑轮可以布置为远离曲轴滑轮一定距离，并且可以联接至HSG并且由HSG进行旋转，HSG选择性地启动发动机并且产生电力；惰轮，惰轮可以能够旋转地布置于从穿过曲轴滑轮和HSG滑轮的第一切线向外一定距离的位置；驱动皮带，曲轴滑轮、HSG滑轮和惰轮可以由驱动皮带的内周界所包裹；机械式自动张紧器(MAT)，机械式自动张紧器从穿过曲轴滑轮和HSG滑轮的第二切线向内推压曲轴滑轮和HSG滑轮之间的驱动皮带，以维持驱动皮带的张力；以及液压式自动张紧器，液压式自动张紧器向内推压曲轴滑轮和惰轮之间的驱动皮带，以维持张力。
摘要（英）：

A drive belt system of a hybrid engine, may include a crankshaft pulley that may be disposed to be rotated by an engine, a hybrid starter generator (HSG) pulley that may be disposed with a distance from the crankshaft pulley and may be coupled to and rotated by a HSG that selectively starts the engine and generates electricity, an idler pulley that may be rotatably disposed at a position with a distance outwards from a first tangential line passing the crankshaft pulley and the, a drive belt that the crankshaft pulley, the and the idler pulley may be wrapped by the interior circumference thereof, a mechanical auto tensioner (MAT) that pushes the drive belt between the crankshaft pulley and the inwards from a second tangential line passing the crankshaft pulley and the to sustain the tension of the drive belt, and a hydraulic auto tensioner that pushes the drive belt between the crankshaft pulley and the idler pulley inwards to sustain the tension.
