Abstract

A modular frame for a track system is disclosed. The modular frame includes an upper frame member operatively connectable to an axle of a vehicle and removably connectable to a first lower frame member. The first lower frame member is configured to connect with at least one of a support wheel assembly and an idler wheel assembly, and connection of the upper frame member to the first lower frame member confers a first lower frame member-specific function to the track system. Another modular frame, track systems having the modular frames, tensioners and track systems having the tensioners are also disclosed.

First claim

What is claimed is:

1. A modular frame for a track system, the modular frame comprising:
an upper frame member operatively connectable to an axle of a vehicle and removably connectable to a first lower frame member, the first lower frame member being configured to connect with at least one of a support wheel assembly and an idler wheel assembly;
wherein the first lower frame member is connectable to the upper frame member in at least two configurations:
in a first of the at least two configurations, the upper frame member is in a first position relative to the first lower frame member;
in a second of the at least two configurations, the upper frame member is in a second position relative to the first lower frame member; and
wherein the first position is different from the second position; and

wherein connection of the upper frame member to the first lower frame member confers a first lower frame member-specific function to the track system.

2. The modular frame of claim 1 , wherein the first lower frame member is replaceable with a second lower frame member, the second lower frame member being configured to connect with at least one of a support wheel assembly and an idler wheel assembly; and wherein connection of the upper frame member to the second lower frame member confers a second lower frame member-specific function to the track system.

3. The modular frame of claim 2 , wherein the first lower frame member is replaceable without disconnection of the upper frame member from the axle.

4. The modular frame of claim 2 , wherein the first lower frame member specific function and the second lower frame member specific function are different.

5. The modular frame of claim 2 , wherein the second lower frame member is configured to operatively connect with one of: two support wheel assemblies, three support wheel assemblies and four support wheel assemblies.

6. The modular frame of claim 2 , wherein:
the first lower frame member induces a first ground contact area;
the second lower frame member induces a second ground contact area, and
the first ground contact area is different from the second ground contact area.

7. The modular frame of claim 1 , wherein when the upper frame member is adjusted from the first of the at least two configurations to the second of the at least two configurations, the first lower frame member moves in at least one of a:
longitudinal direction relative to the upper frame member; and
lateral direction relative to the upper frame member.

8. The modular frame of claim 1 , wherein when the upper frame member is adjusted from the first configuration to the second configuration, the first ground contact area moves in at least one of a longitudinal direction, and a lateral direction.

9. A track system comprising:
the modular frame according to claim 1 ,
a sprocket wheel assembly rotationally connected to the upper frame member;
at least one idler wheel assembly rotationally connected to the first lower frame member;
at least one support wheel assembly rotationally connected to the first lower frame member; and
an elastomeric endless track surrounding the modular frame, the sprocket wheel assembly, the at least one idler wheel assembly and the at least one support wheel assembly.

10. A vehicle comprising:
a frame;
a seat disposed on the frame;
an engine supported by the frame; and
at least two track systems according to claim 9 , the at least two track systems being operatively connected to the engine.

11. A modular frame for a track system, the modular frame comprising:
a first lower frame member removably connectable to an upper frame member, the first lower frame member being configured to connect with at least one of a support wheel assembly and an idler wheel assembly;
wherein the first lower frame member is connectable to the upper frame member in at least two configurations:
in a first of the at least two configurations, the first lower frame member is in a first position relative to the upper frame member; and
in a second of the at least two configurations, the first lower frame member is in a second position relative to the upper frame member,
wherein the first position is different from the second position; and

wherein connection of the first lower frame member to the upper frame member confers a first lower frame member-specific function to the track system.

12. The modular frame of claim 11 , wherein the first lower frame member is replaceable with a second lower frame member, the second lower frame member being configured to connect with at least one of a support wheel assembly and an idler wheel assembly; and wherein connection of the second lower frame member to the upper frame member confers a second lower frame member-specific function to the track system.

13. The modular frame of claim 12 , wherein the first lower frame member-specific function and the second lower frame member-specific function are different.

14. The modular frame of claim 12 , wherein the second lower frame member is configured to operatively connect with one of: two support wheel assemblies, three support wheel assemblies and four support wheel assemblies.

15. The modular frame of claim 12 , wherein:
the first lower frame member induces a first ground contact area;
the second lower frame member induces a second ground contact area, and
the first ground contact area is different from the second ground contact area.

16. The modular frame of claim 11 , wherein the first lower frame member is replaceable with a third lower frame member.

17. The modular frame of claim 11 , wherein when the first lower frame member is adjusted from the first configuration to the second configuration, induced ground contact area moves in at least one of a longitudinal direction, and lateral direction.

18. A track system comprising:
the modular frame according to claim 11 ,
a sprocket wheel assembly rotationally connected to the upper frame member;
at least one idler wheel assembly rotationally connected to the first lower frame member;
at least one support wheel assembly rotationally connected to the first lower frame member; and
an elastomeric endless track surrounding the modular frame, the sprocket wheel assembly, the at least one idler wheel assembly and the at least one support wheel assembly.

19. A vehicle comprising:
a frame;
a seat disposed on the frame;
an engine supported by the frame; and
at least two track systems according to claim 18 , the at least two track systems being operatively connected to the engine.
