Abstract
Described herein are illustrative payload carrying machines and dump body linkage. An example vehicle can include a frame and a dump body movable relative to the frame. In the example vehicle, an articulation mechanism can be connected to both the dump body and the frame. The articulation mechanism can be a four-link system including a first pair of links can be coupled to the frame and dump body and a second pair of links can be coupled to the frame and dump body. The second pair of links can be longer than the first pair of links.
Claims14
A vehicle comprising:
- a frame;
- a dump body movable relative to the frame;
- a linear actuator connected at one end to the frame and at another end to the dump body, the linear actuator configured to be actuated to position the dump body in a lowered position relative to the frame and to be actuated to position the dump body in a raised position relative to the frame;
- and
- an articulation mechanism spaced apart from the linear actuator and connected to the dump body and the frame, the articulation mechanism comprising:
- a first link pivotally connected to the frame at a first pivot point and pivotally connected to the dump body at a second pivot point;
- and
- a second link pivotally connected to the frame at a third pivot point and pivotally connected to the dump body at a fourth pivot point, the first link rotatable about the first and second pivot points and the second link rotatable about the third and fourth pivot points,
- wherein, in the lowered position, the first pivot point is forward of the second pivot point and the third pivot point is forward of the fourth pivot point, and
- wherein, in the raised position, the first pivot point is forward rearward of the second pivot point and the third pivot point is forward of the fourth pivot point.

A vehicle comprising:
- a frame having a front and a rear;
- a dump body having a front and a rear, the dump body being movably connected to the frame;
- a lift actuator coupled to the dump body and to the frame, the lift actuator configured to move the front of the dump body between a lowered position and a raised position relative to the frame;
- a first link pivotally connected to the frame at a first pivot point and pivotally connected to the dump body at a second pivot point;
- and
- a second link pivotally connected to the frame at a third pivot point and pivotally connected to the dump body at a fourth pivot point, the first link having a length, L1, which is less than a second length, L2, of the second link,
- wherein, in the lowered position, the first pivot point is disposed forward of the second pivot point and the third pivot point is disposed forward of the fourth pivot point, and
- wherein, in the raised position, the first pivot point is disposed rearward of the second pivot point and the third pivot point is disposed forward of the fourth pivot point.
