Joystick for a work vehicle

1. A joystick for a work vehicle, the joystick comprising:

a handle defining an external surface configured to provide grip by an operator of the work vehicle; and

hydraulic conditioning means configured to allow the passage of a conditioning fluid into the joystick to regulate the temperature of the handle;

wherein the hydraulic conditioning means are configured to fluidly connect the joystick with a hydraulic conditioning circuit of the work vehicle so as to spill part of a conditioning fluid of the hydraulic conditioning circuit and make this latter circulate in the joystick for regulating the temperature of the handle.

2. The joystick according to claim 1 , wherein the hydraulic conditioning means comprises a system of conduit comprising at least a conduit comprising a first and a second openings configured to fluidly connect the at least one conduit to the hydraulic conditioning circuit of the work vehicle.

3. The joystick according to claim 2 , wherein the at least a conduit is carried by the handle.

4. The joystick according to claim 1 , wherein the handle comprises at least a shell defining an inner volume.

5. The joystick according to claim 4 , wherein the at least a conduit is realized inside the at least one shell.

6. The joystick according to claim 5 , wherein the at least a conduit and the at least one shell are realized monolithically.

7. The joystick according to any claim from 5 , wherein the at least a conduit and the at least one shell are realized by an additive manufacturing process.

8. The joystick according to any claim from 5 , wherein the at least a conduit has a “zig-zag” shape.

9. The joystick according to any claim from 5 , wherein the handle comprises two shells coupled one to the other and wherein the conduit is a single conduit and comprises a first portion extending between the first opening to a first intermediate opening in a first of the two shells and a second portion extending between a second intermediate opening to the second opening in a second of the two shells.

10. A work vehicle comprising:

a conditioning circuit configured to use a conditioning fluid for maintaining the temperature of a portion of the vehicle within a preset temperature; and

a joystick according to claim 1 .

11. The work vehicle according to claim 10 , wherein the circuit further comprises flow regulation means configured to regulate the flow of conditioning fluid passing into the joystick.

12. The work vehicle according to claim 11 , further comprising an electronic control unit and wherein the flow regulation means comprise an electro-actuated valve, the electronic control unit being configured to operate valve on the base of the desired temperature and a measured or estimated temperature of the handle.

13. The work vehicle according to claim 11 , wherein the flow regulation means comprise a mechanically actuated valve.

14. A method for controlling the temperature of the handle of the joystick according to claim 1 , the handle comprising an outer surface, the method comprising:

detecting that the temperature of the outer surface of handle of the joystick is lower than a preset temperature threshold;

allowing the passage of a flow of the conditioning fluid of the conditioning circuit of the work vehicle inside joystick; maintaining the passage of such flow until the temperature of the outer surface of the handle of joystick reaches the preset temperature threshold; and

in response to the temperature of the outer surface of the handle reaching the present temperature threshold, stopping the fluid flow into joystick.
