[CN 201680012390.1] Hydro-mechanical transmission with multiple operating modes Title: Hydro-mechanical transmission with multiple operating modes Application number: CN 201680012390.1 Applicant: Mathers Hydraulic Technology Co., Ltd. Application date: 2016-1-18 Patent type: Invention application The present invention discloses various vehicle systems capable of having different operating modes. According to one example, the system may include at least one input shaft, at least one output shaft, a plurality of hydraulic devices, and one or more accessories. The plurality of hydraulic devices may be configured to be operable as a vane pump in a vane retraction mode of operation and may be configured to be operable as a hydraulic coupling to connect the at least one input shaft with the at least one output shaft in a vane extension mode of operation. A plurality of hydraulic devices may operate simultaneously as a hydraulic coupling and a vane pump. The one or more accessories may be in fluid communication with the plurality of hydraulic devices and may be configured to receive hydraulic fluid pumped from one or more of the plurality of hydraulic devices when the one or more of the plurality of hydraulic devices operates as a vane pump.
