Abstract
An articulated wheel loader provides a cushioned deceleration at the limits of its turning to the left and to the right by reducing fluid flow through a hydraulic steering cylinder as the articulated frames approach abutment. The throttled fluid flow causes a variable displacement pump to de-stroke, which further cushions the deceleration.
