Work vehicle magnetorheological fluid joystick systems operable in modified joystick stiffness modes

Embodiments of a work vehicle magnetorheological fluid (MRF) joystick system include a joystick device having a base housing, a joystick movably mounted to the base housing, and a joystick position sensor configured to monitor joystick movement. An MRF joystick resistance mechanism is controllable to vary a joystick stiffness resisting movement of the joystick relative to the base housing, while a controller architecture is coupled to the joystick position sensor and to the MRF joystick resistance mechanism. The controller architecture is configured to: (i) selectively place the work vehicle MRF joystick system in a modified joystick stiffness mode during operation of the work vehicle; and (ii) when the work vehicle MRF joystick system is placed in the modified joystick stiffness mode, command the MRF joystick resistance mechanism to vary the joystick stiffness based, at least in part, on the movement of the joystick relative to the base housing.

BUTTON STRUCTURE
20230030145 · 2023-02-02 ·

A button structure includes a first component, a second component, and a pressing element mounted on the second component. The first component has a first base portion. The first base portion protrudes outward to form at least one first extending portion. The at least one first extending portion protrudes inward to form a limiting portion. The second component has a second base portion. The second base portion protrudes rearward to form at least one second extending portion. The at least one first extending portion and the at least one second extending portion are connected by a pivoting assembly. The at least one second extending portion protrudes rearward to form a blocking portion. When the blocking portion is pivoted on the first component, the blocking portion is alternatively located to a bottom of the limiting portion and a top of the limiting portion.

A pneumatic brake pedal module for a brake-by-wire brake system of a vehicle is disclosed. The brake pedal module includes a pivotably mounted brake pedal and a damping unit. The damping unit is mechanically coupled to the brake pedal to generate a resistance when the brake pedal is actuated. The damping unit comprises a housing and a piston, which is mounted movably in the housing and divides an internal space of the housing into a pressure chamber and a vacuum chamber. The pressure chamber and the vacuum chamber are connected to one another in terms of flow. The piston has on its running surface an encircling annular space in which a ring seal is accommodated in an axially movable manner. The ring seal is located at least in a flow path between the pressure chamber and the vacuum chamber and forms a restrictor in the at least one flow path, which restrictor frees different flow cross sections in the at least one flow path depending on the axial direction of movement, and damps the movement of the piston with differing degrees of strength depending on a direction of movement of the piston.

A brake pedal module for a “brake-by-wire” brake system of a vehicle is disclosed. The brake pedal module has a pivotably mounted brake pedal and a damping unit. The damping unit is mechanically coupled to the brake pedal in order to generate a resistance when the brake pedal is actuated. The damping unit comprises a housing and a piston mounted in the housing in such a way that it can be moved from an initial position into an end position. In its initial position, the piston is supported on a base of the housing via at least two elastic elements arranged in series. A further elastic element is arranged parallel to the at least two elastic elements on the base of the housing. The further elastic element is not subject to any load in an initial position of the piston.
