SYSTEM FOR DETECTING FAILURE OF AN ACKERMAN-TYPE STEERING MECHANISM

Last updated:

Abstract:

A machine includes a frame, a first steering arm, a second steering arm, a first hydraulic actuator coupled to the frame and the first steering arm, and a second hydraulic actuator coupled to the frame and the second steering arm. A first angle sensor measures a rotational displacement of the first hydraulic actuator relative to the first steering arm. A first link couples the first hydraulic actuator and the first sensor, and isolates movements other than the first rotational displacement. A second angle sensor measures a second rotational displacement of the second hydraulic actuator relative to the second steering arm. A second link couples the second hydraulic actuator and the second sensor, and isolates movements other than the second rotational displacement.
