摘要： A folded bicycle frame comprising a single and continuous sheet of metal is disclosed. The bicycle frame is formed by cutting the sheet of metal to form a boundary, hydroforming the sheet of metal to create a profile comprising indentations and protrusions along the sheet of metal, and then folding the molded sheet essentially along its axis of symmetry, such that the symmetrical parts of the sheet are positioned next to each other to form the frame with a hollow interior. Holes are precut in the frame so that other bicycle parts may be attached to the frame. The frame is produced without the need for any welding or connecting of individual parts. Thus, it is stronger than conventional bicycle frames which are weaker at such welded connections of their parts. A method for making the folded frame is also disclosed.

摘要： A frame unit for a two-wheeled vehicle may comprise a main frame. The main frame may be formed by a first partial shell and a second partial shell that is joined to the first partial shell. The first partial shell and the second partial shell may be produced from a material comprising steel. The main frame may further comprise an upper tube, a lower tube, a seat tube, and/or a head tube. A rear section may be joined to the main frame and may include a chain stay and/or a seat stay. Further, each of the first and second partial shells may form a lateral half of the main frame, and the first and second partial shells may have a C-shaped cross section. The frame unit avoids the disadvantages of the prior art and offers a high degree of design freedom.

摘要： The present invention is directed to an improved frame construction for transmitting in-plane and out-of-plane loads between a plurality of components and maintaining the components in spacial relation. The frame is comprised of a plurality of node members for interconnection with the components and a plurality of beams and skin members interconnecting the node members. The beams include two channels on opposing sides for receiving the outer edges of the skin members. Preferably, the node members and beams form a perimeter channel that extends substantially around the entire perimeter of the frame and the skin members are secured thereto.

摘要： A two-wheeled motorcycle includes a shell for enveloping a power unit for driving a rear wheel of the motorcycle and to the front end of which a head pipe is fixed. The shell is composed of an upper shell half constituted at least by a top plate and right and left side plates, and a lower shell half constituted at least by left and right side plates and a bottom plate. The power unit is connected to the lower shell half to serve also as a mechanical strength member. The upper and lower shell halves are separably connected to each other at the ends of the side plates thereof.

摘要： The invention relates to a bicycle (100) having a frame structure (200) that comprises a swingarm structure (225) including a first substantially U-shaped sheet metal part for holding a wheel (103), the frame structure further comprising a frame bridge (219) consisting of a second substantially U-shaped sheet metal part. The first U-shaped sheet metal part is bent substantially in a first bending plane (P) to form a first U-shape, and the second U-shaped sheet metal part is bent in a second bending plane (Q) to form substantially a second U-shape. The first bending plane extends substantially perpendicular to the second bending plane.
