The present invention relates to a powertrain assembly (PA) comprising a prime mover (101) supported on a main housing (201), the main housing (201) enclosing a drivetrain. The transmission system comprises: a drive shaft assembly (DSA) operably connected to a driven shaft assembly (DSRA) by a transmission tool (206); a cover member (202), the cover member (202) being detachably attached to the main housing (201); and a secondary housing (203), wherein the secondary housing (203) encloses the gear reduction system. Thus, the present subject matter facilitates the operation of a low torque prime mover (101) using a two-stage gearing-down in which the primary transmission is a chain drive and the secondary transmission is a gear drive, thereby reducing slack in the chain drive, which improves the efficiency of the powertrain assembly (PA). In addition, slack due to long-term use in a chain drive is compensated by using a guide tensioner assembly (GTA).

    本发明涉及一种动力系组件(PA),其包括支撑在主壳体(201)上的原动机(101),主壳体(201)围封传动系统。所述传动系统包括:驱动轴组件(DSA),其通过传动工具(206)可操作地连接到从动轴组件(DSRA);盖构件(202),盖构件(202)可拆卸地附接到所述主壳体(201);和副壳体(203),副壳体(203)围封齿轮减速系统。因此,本主题便于使用两级减速传动系统的低扭矩原动机(101)的工作,其中主传动装置为链驱动装置,并且副传动装置是齿轮驱动装置,从而减少了链驱动装置中的松弛,这提高了动力系组件(PA)的效率。此外,通过使用导向张紧器组件(GTA)补偿了在链驱动装置中由于长期使用造成的松弛。
