Track configuration for a farm implement
A track assembly for a farm implement includes a camber arm mounted in a camber arm housing, a first mounting bracket coupled to the upper connection point on the front end and pivotably coupled to the lower pivot point on the front end, and a second mounting bracket coupled to the upper connection point on the back end and pivotably coupled to the lower pivot point on the back end. The track assembly further includes first and second set arms having idler wheel sets mounted on one end and bogie wheel sets mounted on another end. The first set arm is pivotably coupled to the first mounting bracket, and the second set arm is pivotably coupled to the second mounting bracket, such that the idler wheel sets and bogie wheel sets are movable in opposing vertical directions.
1. A farm implement comprising:
left and right track assemblies for assisting in moving the farm implement along a ground surface in a line of travel, wherein each track assembly comprises:
a camber arm mounted in a camber arm housing, such that the camber arm permits the camber arm housing to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel;
wherein the camber arm housing has a front end and a back end, and further has upper connection points on both the front end and back end and lower pivot points on both the front end and back end;
a first mounting bracket coupled to the upper connection point on the front end;
a second mounting bracket coupled to the upper connection point on the back end;
a first set arm having a first idler wheel set mounted on one end and a first bogie wheel set mounted on another end, wherein the first set arm is pivotably coupled to the first mounting bracket such that the first idler wheel set and first bogie wheel set are movable in opposing vertical directions;
a second set arm having a second idler wheel set mounted on one end and a second bogie wheel set mounted on another end, wherein the second set arm is pivotably coupled to the second mounting bracket, such that the second idler wheel set and second bogie wheel set are movable in opposing vertical directions;
wherein one or more of: the first mounting bracket is pivotably coupled to the lower pivot point on the front end and the second mounting bracket is pivotably coupled to the lower pivot point on the back end.
2. The farm implement of claim 1 , further comprising a first suspension member connected to the upper connection point on the front end and between the first mounting bracket and the front end.
3. The farm implement of claim 1 , further comprising a second suspension member connected to the upper connection point on the back end and between the second mounting bracket and the back end, and
wherein both of: the first mounting bracket is pivotably coupled to the lower pivot point on the front end and the second mounting bracket is pivotably coupled to the lower pivot point on the back end.
4. The farm implement of claim 2 , wherein the second mounting bracket is pivotably coupled to the camber arm housing.
5. The farm implement of claim 1 , wherein the first and second mounting brackets are triangle-shaped members.
6. The farm implement of claim 3 , wherein the first and second suspension members comprise one or more of: a hydraulic cylinder having a hydraulic accumulator, a spring, a gas strut, and a shock.
7. The farm implement of claim 1 , wherein the first set arm is pivotable about a seventh axis perpendicular to the line of travel allowing the first bogie wheel set and the first idler wheel set to move generally vertically.
8. The farm implement of claim 1 , wherein the second set arm is pivotable about an eighth axis perpendicular to the line of travel allowing the second bogie wheel set and the second idler wheel set to move generally vertically.
9. The farm implement of claim 1 , wherein the first axis perpendicular to the line of travel is movable generally vertically when the farm implement transitions from an unloaded configuration to a loaded configuration.
