  • PTO LUBRICATION SYSTEM FOR HYBRID VEHICLES
    Publication number: 20240133462
    Abstract: A vehicle drive system includes a first prime mover, a transmission, a power take-off (PTO), a lubrication system for the transmission and the PTO, and a control system. The transmission is powered by the first prime mover. The transmission is configured to rotate a drive shaft of the vehicle. The PTO is connected to the transmission at a first interface. The PTO includes the first interface and a second interface. The control system is configured to control fluid flow through the lubrication system for at least one mode where the input section of the PTO is stationary and the output section rotates.
