Abstract
A travel jolt minimizing assembly for use in association with an articulated loader steering environment having a orbitrol pump, and a flow amplifier coupled to the orbitrol pump through a left orbitrol signal and a right orbitrol signal, and a steering cylinder coupled to the flow amplifier. The travel jolt minimizing assembly includes a system for temporarily diverting the left orbitrol signal within a predetermined degrees of a full articulation in a left direction and a system for temporarily diverting the right orbitrol signal within a predetermined degrees of a full articulation in a right direction. The invention further includes a response cushion assembly which minimizes jolts which occur upon a rapid change in direction.
