Track-module bogie-suspension apparatus for attachment to a track module having a frame, a drive wheel and an endless track. The bogie-suspension apparatus comprises (a) a bogie assembly having a bogie mount, at least one rotatable ground-engaging bogie wheel thereon, and forward and rearward bogie-mount connections; (b) first and second load- and ground-responsive suspension joints spaced from one another in a forward/rearward direction; and (c) leading and trailing suspension elements each having an upper end and a lower end, the upper ends of the leading and trailing suspension elements rotatably attached to the first and second suspension joints, respectively, and the lower ends thereof rotatably attached to the rearward and forward bogie-mount connections, respectively.
(canceled)
The bogie-suspension apparatus of claim 33 further including a third load- and ground-responsive suspension joint and wherein the bogie assembly further includes a bogie-assembly arm rotatably attached (a) at a bogie-assembly arm distal end to the third suspension joint and (b) at a bogie-assembly arm proximal end to the bogie mount.
(canceled)
The bogie-suspension apparatus of claim 33 including at least two leading bogie wheels and at least two trailing bogie wheels and wherein the leading bogie axis rotates on a leading bogie roll axis perpendicular thereto and the trailing bogie axis rotates on a trailing bogie roll axis perpendicular thereto.
The bogie-suspension apparatus of claim 33 wherein the bogie-mount forward and rearward portions are rotatably attached at a third bogie-assembly axis.
The bogie-suspension apparatus of claim 33 wherein the bogie mount further includes a bogie-mount middle portion having at least one middle bogie wheel attached thereto at a middle bogie axis.
The bogie-suspension apparatus of claim 33 wherein the leading and trailing suspension elements each include gas-filled components to provide spring force.
The bogie-suspension apparatus of claim 33 including plural bogie wheels and wherein the bogie wheels have diameters which are substantially the same as each other.
The bogie-suspension apparatus of claim 33 wherein the first and second load- and ground-responsive suspension joints are independently responsive to load and ground variations.
(canceled)
The bogie-suspension apparatus of claim 33 wherein movements of the first and second load- and ground-responsive suspension joints are interdependent.
(canceled)
Track-module bogie-suspension apparatus for attachment to a track module having a frame, a drive wheel and an endless track, comprising:
