Abstract

A drive train linkage includes a drive arm having a drive arm pivot axis, a driven arm having a driven arm pivot axis, at least one first coupling member extending between and being rotatably coupled to each of the drive arm and driven arm, and at least one second coupling member extending between and being rotatably coupled to each of the drive arm and driven arm so that the at least one second coupling member opposes the at least one first coupling member, where the at least one first coupling member and the at least one second coupling member are coupled to both the drive arm and the driven arm so to form a substantially zero mechanical deadband coupling between the drive arm and the driven arm.

Dependent claims

A drive train linkage comprising:

a drive arm having a drive arm body defining a drive arm pivot axis, where the drive arm body is a rigid member and pivots about the drive arm pivot axis;
a driven arm having a driven arm body defining a driven arm pivot axis, where the driven arm body is a rigid member and pivots about the driven arm pivot axis under impetus of the drive arm;
at least one first coupling member extending between and being rotatably coupled to each of the drive arm and driven arm;
and
at least one second coupling member extending between and being rotatably coupled to each of the drive arm and driven arm so that forces exerted on both the drive arm and driven arm by the at least one second coupling member oppose forces exerted on both the drive arm and the driven arm by the at least one first coupling member;
where the at least one first coupling member and the at least one second coupling member are coupled to both the drive arm and the driven arm so to form a substantially zero mechanical deadband coupling between the drive arm and the driven arm.
