Method for producing a component system having a first component with a first component portion and a second component with a second component portion, including the following steps: connecting, in particular welding or soldering, the first component portion, which consists of an aluminum alloy, to the second component portion, which in particular consists of a naturally aged aluminum alloy, a copper alloy or an iron alloy, in particular a steel alloy, so as to form a connection seam; artificially aging the connection seam such that the yield strength of the connection seam is above the yield strength of the first component portion and/or of the second component portion; and deforming, in particular deep-drawing and/or stretch-drawing, the component system.

In a rocking vehicle, a front wheel suspension device suspends a front wheel in an upwardly displaceable manner due to a reaction force from a road surface. The rocking vehicle includes a cushion support arm, on a body frame side, including a cushion support portion of the front wheel suspension device, and a rigidity adjustment device which is extended between plural portions of the cushion support arm. The rigidity adjustment device applies a pre-tension to the cushion support arm, and the pre-tension generates a pre-force component in the cushion support portion in the same direction as the upward moving direction of the front wheel due to a reaction force of the front wheel from the road surface.

A body structure of a saddle riding vehicle includes a head pipe, and a pair of left and right side gussets connected to the head pipe, wherein an internal space in which a vehicle component is disposed is formed between the pair of left and right side gussets in a vehicle width direction, an opening section opened in a forward/rearward direction is formed in the side gussets, and an opening-side flange curved inward in the vehicle width direction is formed at an outer circumferential edges of the opening sections of the side gussets.

A method for manufacturing a hollow vehicle frame part includes: removing material from a first side of a first billet to create a first inner shape of a target vehicle frame such a substantially angled faying surface remains adjacent to the first inner shape; removing material from a first side of a second billet to create a second inner shape, such that a substantially angled faying surface is left on the first side of the second billet adjacent to the second inner shape; bonding the first and second billets together at the faying surfaces such that the first and second inner shapes face each other and such that the angled faying surfaces together form a bevel-type joint; after bonding, removing material by machining from the second sides of the first and second billets to create target outer shape of the vehicle frame part.

A motorcycle body frame structure improves rigidity and further suppresses changes in vehicle body behavior. The body frame structure includes: a head pipe, right and left main frames connected to the head pipe, a down tube connected to the head pipe, right and left reinforcing frames installed between the down tube and corresponding right and left reinforcing frames. Each of the right and left reinforcing frames include a first and second joint portions joined to the down tube. The first joint portions are joined with corresponding right and left main frames. Each of the second joint portions include a first joint flange portion welded with corresponding right and left side surfaces of the down tube, a second joint flange portion welded with an upper surface of the down tube, and a third joint flange portion connected with the first and second joint flange portions and separated from the down tube.

A joint structure of a composite bicycle frame includes a base layer and at least one reinforcing layer. The base layer is made of a first polymeric matrix material doped with a plurality of first fibers. The first fibers have random fiber orientation, and the base layer has a first thickness. The reinforcing layer is adhesively connected to the base layer. The reinforcing layer is made of a second polymeric matrix material doped with a plurality of second fibers. The second fibers have a single fiber orientation. The reinforcing layer has a second thickness which is smaller than the first thickness of the base layer.

A bike frame with a fixed bottle opener gusset is a bicycle frame with at least a crossbar, a vertical-frame bar, and a fixed bottle opener gusset fixedly and integrally located at an intersection of the crossbar and said vertical frame-bar. The design of the frame provides added strength and increased frame life with rugged service while further providing a user with a functional bottle opener that is useful for removing a cap from a bottle when the user is riding or not riding the bicycle.

An inverted tube bike frame with bottle opener gusset system is a bicycle frame with the top tube and down tube having a heightened profile with concave sidewalls and a bottle opener gusset strengthening the joint between the seat tube and the top tube. The top tube has a downwardly curved design for added mechanical strength. Other tube-members of the frame have an elongated elliptical cross-section for increased strength and impact damage resistance. The wheel base is wider than that of a standard bicycle adding to forward movement stability and rider comfort. The design of the frame provides added strength and increased frame life with rugged service.

A vehicle body frame of a saddle-ride-type vehicle which enables a high-strength joint and a reduction in the weight of the vehicle body frame. The vehicle body frame of a saddle-ride-type vehicle includes a plurality of rear frames arranged to face each other in an opposed manner and a cross frame for connecting the plurality of rear frames to each other. A through hole is formed in the rear frames arranged to face each other in an opposed manner with the cross frame being joined to the rear frames at insertion portions thereof inserted into the through holes.
