Abstract: A hydrostatic driveline is provided. The hydrostatic driveline comprises a power source, a hydrostatic pump, a hydrostatic motor, a direct drive link, and a transmission portion. The power source is drivingly engaged with an input member. The hydrostatic pump is in driving engagement with the input member. The hydrostatic motor is in fluid communication with the hydrostatic pump. The direct drive link is in driving engagement with the input member. The transmission portion is in driving engagement with a vehicle output and at least one of the hydrostatic motor and the direct drive link The transmission portion includes at least one engagement device and a drive ratio. The hydrostatic pump, the hydrostatic motor, and the transmission portion form a first power path for the hydrostatic driveline and the direct drive link forms a second power path for the hydrostatic driveline.

Abstract translation: 提供静液压传动系统。 静液压传动系统包括动力源，静液压泵，静液压马达，直接驱动连杆和传动部分。 电源驱动地与输入构件接合。 静液压泵与输入构件驱动接合。 静液压马达与液压泵流体连通。 直接驱动链接与输入构件的驱动接合。 传动部分与车辆输出驱动接合，并且静液压马达和直接驱动连杆中的至少一个传动部分包括至少一个接合装置和驱动比。 静液压泵，静液压马达和传动部分形成用于静液压传动系的第一动力通道，并且直接驱动连杆形成用于静液压传动系的第二动力通路。
