1. A vehicle comprising:
- a frame including at least one mounting lug and at least one tubular component coupled together through a structural adhesive;
the mounting lug including an extension portion having a diameter larger than the tubular component that overlaps the tubular component, the extension portion defining a cavity intermediate the mounting lug and tubular component, the cavity being defined by an annular recess on one of the mounting lug or the tubular component and a lip at an end of the mounting lug extension portion closing off the cavity;
at least one mechanical coupler positioned at a location spaced from the annular recess, the at least one mechanical coupler locating the tubular component relative to the mounting lug;
a plurality of ground engaging members including one or more front ground engaging members supporting a front portion of the frame and one or more rear ground engaging members supporting a rear portion of the frame;
a power train system supported by the frame and operatively coupled to at least one of the plurality of ground engaging members;
a straddle seat supported by the frame; and
a steering assembly operatively coupled to at least the one or more front ground engaging members to orient the one or more front ground engaging members, wherein at least one of the plurality of ground engaging members is an endless track operatively coupled to the power train, and in that the mounting lug and the tubular component cooperate to provide at least a portion of a tunnel covering at least a portion of the endless track.

Abstract
A vehicle is shown such as a snowmobile, where a frame includes a tunnel and a front frame portion comprised of cast halves. A suspension system is comprised of upper and lower control arms connected to the front frame portion. Some of the frame components are adhesively fixed together. A powertrain is supported by the frame, and is comprised of an engine and a clutch. The clutch includes a clutch guard supporting an oil container. The engine has an exhaust system which extends through the front frame portion. The snowmobile also has a rear snow deflector.

15. A method of assembling a snowmobile frame, comprising the steps of:
-
providing a first frame member of the snowmobile and a second frame member of the snowmobile, where the first and second frame members overlap to define a closed intersection; positioning the first frame member of the snowmobile relative to the second frame member of the snowmobile; aligning the first and second frame members together by joining the first frame member of the snowmobile to the second frame member of the snowmobile with a mechanical coupler which passes through an opening in at least one of the first frame member of the snowmobile and the second frame member of the snowmobile; defining a cavity intermediate the first and second frame members within the closed intersection, the cavity being defined by an annular recess on one of a mounting lug or a tubular component and a lip at an end of the mounting lug extension portion closing off the cavity; and securing the first frame and second frame members of the snowmobile by filling the cavity with a structural adhesive after joining the first frame member to the second frame member with the mechanical coupler, the mechanical coupler being spaced apart from the structural adhesive. - View Dependent Claims (16, 17, 18)
