Abstract
A frame material for a motor vehicle comprising a structure having an elongated hollow body of a rectangular cross section and a honeycomb member having a multiplicity of independent chambers and arranged in the hollow body such that central axes of the chambers are directed substantially perpendicularly to longer sides of the rectangular cross section of the hollow body. A frame construction for use in a motor vehicle includes the frame material as a main frame interconnecting a head pipe and a rear fork pivot rectilinearly in side elevation.
Claims12
A frame construction for use in a motor vehicle having front and rear forks, comprising:
- (a) a main frame including a head pipe for supporting the front fork angularly movably and a pivot for supporting the rear fork swingably;
- (b) said main frame comprising a pair of right and left first structures and a cross member interconnecting said first structures, each said first structure comprising an elongated hollow body having a rectangular cross section and a honeycomb member disposed in said hollow body and having a multiplicity of independent divided chambers;
- (c) said honeycomb member being arranged such that said divided chambers have central axes directed substantially perpendicularly to longer sides of the rectangular cross section of said hollow body;
- (d) each said first structure of said main frame extending substantially rectilinearly in side elevation along a line interconnecting said head pipe and said pivot;
- and
- (e) said pair of first structures and said cross member jointly constituting substantially an isosceles triangle with said head pipe located in plan at a vertex subtending said cross member.
A frame construction for use in a motor vehicle having front and rear forks, comprising:
- (a) a main frame including a head pipe for supporting the front fork angularly movably and a pivot for supporting the rear fork swingably;
- (b) said main frame comprising a first structure comprising an elongated hollow body having a rectangular cross section and a honeycomb member disposed in said hollow body and having a multiplicity of independent divided chambers;
- (c) said honeycomb member being arranged such that said divided chambers have central axes directed substantially perpendicularly to longer sides of the rectangular cross section of said hollow body;
- (d) said main frame extending substantially rectilinearly in side elevation along a line interconnecting said head pipe and said pivot;
- and
- (e) a rear frame which is positionally adjustable in a longitudinal direction of said main frame on a surface thereof to which said rear frame is joined.
A frame construction for use in a motor vehicle having front and rear forks, comprising:
- (a) a main frame including a head pipe for supporting the front fork angularly movably and a pivot for supporting the rear fork swingably;
- (b) said main frame comprising a first structure comprising an elongated hollow body having a rectangular cross section and a honeycomb member disposed in said hollow body and having a multiplicity of independent divided chambers;
- (c) said honeycomb member being arranged such that said divided chambers have central axes directed substantially perpendicularly to longer sides of the rectangular cross section of said hollow body;
- (d) said main frame extending substantially rectilinearly in side elevation along a line interconnecting said head pipe and said pivot;
- and
- (e) said main frame comprises a pair of said first structures arranged substantially symmetrically with respect to a vertical plane including a longitudinal central axis of the main frame, said first structures having distal ends coupled to said head pipe, and a cross member extending transversely and interconnecting said first structures, said pair of first structures and said cross member jointly constituting substantially an isosceles triangle with said head pipe located in plan at a vertex subtending said cross member.
