Abstract

Embodiments relate to an off-road vehicle comprising a frame, including at a frame, a passenger compartment, a driveline that includes at least a drive system and a driven system, and a constant velocity (CV) joint for coupling the driven system to the drive system. The CV joint includes a housing, a coupling shaft, a detent, a plunge pin and an actuation pin, wherein the actuation pin has a first end that is accessible via an aperture in the housing, wherein actuation of the actuation pin determines whether the plunge pin is in the first position or the second position.

First claim

What is claimed is:

1. An off-road vehicle comprising:
a frame;
a passenger compartment;
a driveline that includes at least a drive system and a driven system;
a constant velocity (CV) joint coupled to the drive system and the driven system, wherein the CV-joint comprises:
a housing having a first end for engaging a driven shaft and a second end opposite the first end;
a coupling shaft located at the second end of the housing, the coupling shaft configured for engagement with the drive system;
a detent extending to an outer periphery of the coupling shaft and configured to maintain engagement between the coupling shaft and the drive system;
a plunge pin disposed at least partially within the coupling shaft and movable relative thereto, the plunge pin having a first position that maintains the detent in an engaged position with the drive system and a second position in which the plunge pin is moved away from the first end of the housing to permit disengagement of the detent with the drive system; and
an actuation pin located adjacent to the plunge pin and extending in a direction non-parallel to the plunge pin, wherein the actuation pin has a first end that is accessible via an aperture in the housing, wherein actuation of the actuation pin determines whether the plunge pin is in the first position or the second position.

2. The off-road vehicle of claim 1 , wherein, when the plunge pin is in the first position the actuation pin is oriented in a first configuration and when the plunge pin is in the second position, the actuation pin is oriented in a second configuration; the second configuration being rotated about its centerline axis relative to the first configuration.

3. The off-road vehicle of claim 2 , wherein the actuation pin is rotated approximately 90 degrees to actuate the plunge pin between the first position and the second position.

4. The off-road vehicle of claim 1 , wherein the actuation pin includes a first portion recessed from an outer periphery of the actuation pin that is in contact with the plunge pin when the plunge pin is in the first position.

5. The off-road vehicle of claim 4 , wherein the plunge pin is in contact with the outer periphery of the actuation pin when the plunge pin is in the second position.

6. The off-road vehicle of claim 5 , wherein the actuation pin rotates about a centerline axis to selectively place the plunge pin in contact with the first portion of the actuation pin or the outer periphery of the actuation pin.

7. The off-road vehicle of claim 5 , wherein the actuation pin moves in an axial direction transverse to an axis of the plunge pin to selectively place the plunge pin in contact with the first portion of the actuation pin or the outer periphery of the actuation pin.

8. The off-road vehicle of claim 7 , wherein the actuation pin has a second end opposite the first end, wherein a bias spring is in contact with the second end, wherein the bias spring is compressed to place the plunge pin in contact with the outer periphery of the actuation pin.

9. The off-road vehicle of claim 1 , wherein the plunge pin further includes a bias spring that is uncompressed when the plunge pin is in the first position and compressed when the plunge pin is in the second position.

10. The off-road vehicle of claim 1 , wherein the drive system is a transaxle and the driven system includes a rear half-shaft and a joint.

11. The off-road vehicle of claim 10 , wherein the joint is a constant velocity (CV) joint.

12. The off-road vehicle of claim 1 , wherein the drive system is a front differential and the driven system includes a front half-shaft and a joint.

13. The off-road vehicle of claim 12 , wherein the joint is a constant velocity (CV) joint.

14. A constant velocity joint comprising:
a housing having a first end for engaging a driven shaft and a second end opposite the first end;
a coupling shaft located at the second end of the housing, the coupling shaft configured for engagement with a drive system;
a detent extending to an outer periphery of the coupling shaft and configured to maintain engagement between the coupling shaft and the drive system during operation;
a plunge pin disposed at least partially within the coupling shaft and movable relative thereto, the plunge pin having a first position that maintains the detent in an engaged position with the drive system and a second position in which the plunge pin is moved away from the first end of the housing to permit disengagement of the detent with the drive system; and
an actuation pin located adjacent to the plunge pin and extending in a direction non-parallel to the plunge pin, wherein the actuation pin has a first end that is accessible via an aperture in the housing, wherein actuation of the actuation pin determines whether the plunge pin is in the first position or the second position.

15. The constant velocity joint of claim 14 , wherein the actuation pin includes a first portion recessed from an outer periphery of the actuation pin that is in contact with the plunge pin when the plunge pin is in the first position.

16. The constant velocity joint of claim 15 , wherein the plunge pin is in contact with the outer periphery of the actuation pin when the plunge pin is in the second position.

17. The constant velocity joint of claim 16 , wherein the actuation pin is rotated to selectively place that plunge pin in contact with the first portion of the actuation pin or the outer periphery of the actuation pin.

18. The constant velocity joint of claim 16 , wherein the actuation pin is moved in an axial direction transverse to an axis of the plunge pin to selectively place the plunge pin in contact with the first portion of the actuation pin or the outer periphery of the actuation pin.

19. The constant velocity joint of claim 18 , wherein the actuation pin has a second end opposite the first end, wherein a bias spring is in contact with the second end, wherein the bias spring is compressed to place the plunge pin in contact with the outer periphery of the actuation pin.

20. A constant velocity (CV) joint assembly comprising:
a CV housing having a radially extending aperture and coupling shaft extending from the housing, the coupling shaft defining a hollow portion therein;
a plunge pin extending within at least a portion of the hollow portion of the coupling shaft, the plunge pin having a first configuration and a second configuration in which the plunge pin is axially offset from the first configuration; and
an actuation pin extending within the aperture, the actuation pin having a recessed portion, wherein at least a portion of the plunge pin is in contact with the actuation pin in both the first and second configurations and, in the first or second configuration at least a portion of the plunge pin is in contact with the recessed portion.
