Vehicle steering assembly
11787462 · 2023-10-17 · ·

A vehicle steering assembly for controlling movement of a vehicle having independently rotatable left and right ground-engaging traction elements. The steering assembly comprises a steering handle coupled to the panel support structure and extending generally upwardly from the panel support structure. The steering handle comprises a laterally-extending crossmember and at least one upright extension member. The crossmember and the upright extension member are rigidly connected to one another so that shifting of the crossmember relative to the extension member is substantially prevented. The steering handle is shiftable in forward and rearward directions to thereby cause corresponding forward and rearward rotation of both of the left and right traction elements. The steering handle is rotatable in clockwise and counterclockwise directions to thereby cause a change in the relative speeds and directions of rotation of the left and right traction elements.

WORK VEHICLE MAGNETORHEOLOGICAL FLUID JOYSTICK SYSTEMS OPERABLE IN MODIFIED CENTERING MODES
20210341960 · 2021-11-04 ·

In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device, an MRF joystick resistance mechanism, and a controller architecture. The joystick device includes, in turn, a base housing, a joystick movably mounted to the base housing, and a joystick bias mechanism coupled to the joystick and exerting a centering force urging the joystick to return to the centered position when moved therefrom. The controller architecture is operable in a modified centering mode in which the controller architecture: (i) determines when the joystick begins return toward the centered position due to the centering force applied by the joystick bias mechanism; and (ii) when so determining, commands the MRF joystick resistance mechanism to modify a rate at which the joystick returns to the centered position by varying the MRF resistance force applied to the joystick.

Riding lawn mower and operating apparatus with position detection for the same

A riding lawn mower includes a chassis, a power output assembly, a walking assembly, a power supply device, a control module, and an operating apparatus. The operating apparatus includes at least one bracket, an operating lap bar assembly, a pivoting assembly, and a position detecting module. The pivoting assembly mounts the operating lap bar of the operating lap bar assembly on the bracket. The operating lap bar can rotate around different positions in a first direction F1 and/or a second direction F2. The position detecting module includes a magnetic element and a magnetic sensor. The magnetic element is provided on the pivoting assembly or the bracket and the magnet sensor is spaced from the magnetic element so that the magnetic element and the magnetic sensor can generate a relative movement for detecting the position of the operating lap bar in the first direction F1 and/or the second direction F2.
