Embodiment Construction

[0057] On all these drawings, the same or similar reference numerals designate the same or similar parts or groups of parts.

[0058]figure 1 A remote control for a heavy vehicle or an agricultural vehicle representing a typical manipulator 1 . This manipulator comprises a lever 3 forming an actuator added to a body 5 . Means 7 for positioning the lever 3 are arranged between the lever 3 and the body 5 . The positioning device 7 is protected by a bellows 9 through which it is visible through transparency. The lever 3 is movable, rotating relative to the body 5 about the z-axis. The lever 3 can follow a trajectory according to such degrees of freedom.

[0059] The positioning device 7 is realized by a corrosion-resistant material, such as stainless steel. This allows preventing the appearance of microscopic cracks that could weaken the positioning means 7 and cause it to break.

[0060] figure 2 and image 3 The positioning device 7 is shown. In this embodiment, the po...

Abstract

The present invention relates to a positioning device (7) for a hydraulic and / or electronic remote control of a heavy duty vehicle or agricultural vehicle, which comprises an elastic element comprising a fastening portion intended to be secured to the body of the remote control and a retaining portion arranged to cooperate with the actuator at a threshold position delimiting a first portion of the displacement trajectory of the actuator, and a second portion of the displacement trajectory, in such a manner as to oppose the movement of the actuator according to its displacement trajectory along at least one displacement direction upon switching of said threshold position and allow the switching at the threshold position in said displacement direction as a result of the application of a threshold switching force exerted on the actuator, the threshold switching force being higher than the displacement force necessary for the movement of the actuator on the first portion of the displacement trajectory or the second portion of the displacement trajectory.

Description

technical field [0001] The invention relates to positioning devices for hydraulic and / or electronic remote controls of heavy vehicles or agricultural vehicles, in particular to handlers or foot switches. Background technique [0002] It is known to implement an electronic remote control for heavy vehicles or agricultural vehicles, comprising an actuator and a body movable relative to the body according to at least one degree of freedom of movement based on a displacement trajectory. [0003] The relative position of the actuator with respect to the body allows defining the controls to be applied to the system controlled by the remote. By way of example, the lever of a hydraulic manipulator can adopt several positions, each position corresponding to a certain hydraulic force and thus determining the behavior of the manipulator. [0004] Certain positions of the actuator may also correspond to different control modes, enabling, for example, depending on the use, the stability...
