Drive train for motor vehicle has hydraulic motor for each wheel, with synchronous control of motor valves depending on vehicle speed

摘要

The drive train includes a drive motor for hydraulic pumps sending hydraulic fluid to four drive wheels, each of which has a small hydraulic motor with several chambers. The cross section of all the chambers corresponds to the input and output cross section. If individual chambers are blocked by the valves, the through-flow speed in the open chambers increases, and so does the speed of the driven wheel, while the fluid speed in the input and output lines remains the same.
