Title:
ROTATION POSITION DETECTION MECHANISM FOR TRUNNION AXIS
Document Type and Number:
WIPO Patent Application WO/2013/105581
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a rotation position detection mechanism (10) for a trunnion axis which is capable of suppressing effects of the operation state of an operation tool in order to reliably detect a predetermined rotation position of the trunnion axis (2). The present invention is a rotation position detection mechanism (10) for a trunnion axis in a hydraulic stepless transmission wherein, by way of a rotation operation of the trunnion axis (2), the rotation speed and the like of an output axis (3) can be modified. The invention is provided with an operating lever (11) one side end of which is supported by the trunnion axis (2) so as to be incapable of relative rotation and which is configured to be capable of rotating the trunnion axis (2), a follower lever (13) a middle section of which is supported by the trunnion axis (2) so as to be capable of free relative rotation, and a detection switch (17). For the operating lever (11), a link (8) for operating the operating lever (11) is connected to the middle portion thereof so that, when rotated by the link (8), the other side end portion of the operating lever comes into tactile contact with one side end portion of the follower lever (13) so as to rotate the follower lever (13) in order to switch between on and off for the detection switch (17). When the operating lever is rotated to another direction from a rotation position γ0, the other side end portion spaces apart from the one side end portion of the follower lever (13).
