Abstract
A frame for an ATV comprises a support module with a central opening defining an engine receiving space. The support module includes a first frame member and a second frame member with at least one cross member extending between the first and second frame members. At least a portion of the support module, which includes one of the frame members and the at least one cross member, consists essentially of a single beam. The single beam may be considered a modular central beam of the frame.
Claims128
A frame for an ATV comprising:
- a first frame member;
- a second frame member;
- at least a first cross member and a second cross member extending between said first and second frame members to thereby define a closed perimeter with an engine receiving space therein;
- first and second suspension mounting points associated with at least one of the first frame member, the second frame member, the first cross member, and the second cross member;
- and
- wherein at least one of the first frame member and the second frame member is positioned substantially along a longitudinal centerline of the frame and extends from the first suspension mounting point to the second suspension mounting point.
3 more elements
An ATV comprising:
- an engine;
- at least three wheel assemblies, at least one of the at least three wheel assemblies being powered by said engine;
- a steering system operatively coupled to at least one of said at least three wheel assemblies;
- a suspension system operatively coupled to each of said wheel assemblies;
- and
- a frame, said frame including:
- an upper frame member;
- a lower frame member;
- at least a forward cross member and a rearward cross member extending between said upper and lower frame members to thereby define a closed perimeter with an engine receiving space therein,
- first and second suspension mounting points associated with at least one of the upper frame member, the lower frame member, the forward cross member, and the rearward cross member;
- and
- wherein at least one of the upper frame member and the lower frame member is positioned substantially along a longitudinal centerline of the frame and extends from the first suspension mounting point to the second suspension mounting point.
