  • Wheel Assist Drive with Traction Control System and Method
    Publication number: 20150233094
    Abstract: A wheel assist drive system and method are provided for use on a machine, such as a motor grader. The wheel assist drive system includes a free-wheeling valve for providing all-wheel drive, a flow divider valve for providing traction control, and a bypass valve for selectively bypassing the flow divider valve. Operation of the bypass valve is based on the status of the free-wheeling valve to reduce heat generation and losses attributable to hydraulic fluid flow through the flow divider valve.

  • Brake system having a brake capacity test mode for a machine having a hydrostatic drivetrain
    Patent number: 9097341
    Abstract: A brake system and method includes a test mode for determining a capacity of the brake system provided on a machine having a hydrostatic drive. A hydrostatic drive target differential pressure range is determined to simulate a test torque. A machine ground speed limit, hydrostatic drive actual differential pressure, and actual ground speed of the machine are determined. An output pressure of the hydrostatic pump is modulated to drive the hydrostatic drive actual differential pressure toward the hydrostatic drive target differential pressure range. A first test fault condition is determined when the actual ground speed exceeds the machine ground speed limit. A second test fault condition is determined when the hydrostatic drive actual differential pressure is outside the hydrostatic drive target differential pressure range.
