  • Publication number: 20120325612
    Abstract: The striper has a solid direct drive axle 12 powered either by chain, belt, gears, hydraulics, etc. 14. Two wheels 16 are attached to a solid axle 12 by means of adjustable friction devices 18 that transfer torque—stacked hardened thrust washers 20 with spring washers 22 to maintain a constant drive torque with ability to have limited slip at a specific load range. The spring washers 22 allow consistent load over long periods of wear. When each tire 24 is properly loaded “equally” the striper 26 will have natural ability to travel in a straight forward motion over bumpy surfaces specifically grass (turf), not common with standard type differentials that power only the least resistant wheel 16. When cornering the inside wheel 16 will slip as necessary based on the turning radius. When the wheels 16 are overloaded, wheels will slip, preventing damage to the drive mechanism (transmission) 28.
