  • Retarding system that retards motion of power source
    Patent number: 8214113
    Abstract: A retarding system for a mobile machine is disclosed. The machine may have a power source and a traction device driven by the power source. The retarding system may have a speed sensor configured to generate a speed signal indicative of a speed of the machine. Additionally, the retarding system may have a service brake configured to retard motion of the traction device. The retarding system may also have an engine brake configured to retard motion of the power source. In addition, the retarding system may have a controller in communication with the speed sensor, the service brake, and the engine brake. The controller may be configured to substantially concurrently retard motion of the traction device based on the speed signal and retard motion of the power source based on the speed signal.

  • Method and system for preventing excessive tire wear on machines
    Publication number: 20080004763
    Abstract: A method for automatically controlling the ton-miles-per-hour of a plurality of tires on a machine includes determining the weight of a load supported by the tires, determining the ground speed of the machine, and compensating for uneven distribution of the load on the tires. The ton-miles-per-hour for each tire is determined based on the compensated load distribution and the ground speed. An operator of the machine is notified if the calculated ton-miles-per-hour exceeds a predetermined threshold. The method also includes adjusting at least one operational aspect associated with the machine if the calculated ton-miles per hour exceeds the predetermined threshold.
