   A hydrostatic CVT's power-transmission capacity is readily adapted to the application by using a correctly-sized pump and matching hydraulic motor(s). Flexibility. As power transfer from the engine-driven pump to the hydraulic motor(s) is through the medium of flowing oil, the motor(s) can be mounted in otherwise-inconvenient locations by using ...

   This design enables the lubricating and cooling oil volume flow to be regulated as required and makes the 9G-Tronic start/stop-capable. [1] When the drive motor is at a standstill, the transmission remains ready to start solely due to the supply from the electric auxiliary pump. Filter elements for the two pumps are integrated in the plastic ...
