20080246263 | STRUCTURAL MEMBER FOR VEHICLE - A structural member for a vehicle has a slot extending into one structural wall thereof, for receiving and holding a bolt, wherein said structural member including said slot has been formed by extrusion. The slot extends the length of the structural member for slidably receiving the head of one or more bolts wherein the land area of each bolt head extends beyond the slot opening to overlay the wall area carrying the slot. Each bolt carries at least two flat faces below its head wherein the juxtaposed edges of the slot carrying wall retains, i.e., refrains, the bolt from rotating. The slot includes an interior wall or sidewalls continuous with the slotted structural wall. The structural member may include an I-beam, a rectangular tube, a C-channel and the like. Corners are radiuses and right angles are avoided to reduce or remove stress risers. | 10-09-2008 |
20090230666 | Vehicle frame joint for a saddle-type vehicle, and vehicle frame incorporating same - A vehicle frame structure for a saddle-type vehicle has a vehicle frame including a subframe portion detachably mounted on a main frame, and a joint between the main frame and the subframe which is disposed in a longitudinally intermediate portion of a continuously extending frame component, wherein the frame component is kept rigid and the joint is maintained in a small size. In the joint, the frame component has a portion divided by a vertical plane into a main-frame-side joint arm and a subframe-side joint arm. The joint arms have distal ends having arcuate outer walls cut off around their fastening positions. The joint arms further have integral upstanding walls disposed on proximal ends thereof, corresponding to the cut-off arcuate outer walls of the joint arms. The joint arms are fastened to each other with the distal ends thereof fitted in cavities surrounded by the upstanding walls. | 09-17-2009 |
20100156082 | METHOD FOR MANUFACTURING A FRAME MEMBER FOR A VEHICLE, AND A FRAME MEMBER FOR A VEHICLE - A method for manufacturing at least one frame member for use as a support element in a vehicle frame includes providing a tubular element. According to the method, a pressure is applied in the interior of the tubular element while the tubular element is positioned at least partly inside a mould, thereby causing the tubular element to conform to the internal shape of said mould so as to change the longitudinal extension direction and/or cross-section of the tubular element in at least one position along the tubular element. A frame member is also provided. | 06-24-2010 |
20110049855 | VEHICLE FRAME STRUCTURE AND VEHICLE INCORPORATING SAME - A vehicle frame structure includes a central frame member, extending in a vehicle longitudinal direction at a central portion of a body frame. The central frame member includes a front end joined to a second front cross pipe, and a rear end joined to a second lower crossmember behind the second front cross pipe. When viewed from the side, the central frame member extends in a substantially straight line along with the left and right front reinforcing pipes. The front end portion of the central frame member is joined to the second front cross pipe at a position inwardly of a joint between the left front reinforcing pipe and the second front cross pipe, and inwardly of a joint between the right front reinforcing pipe and the second front cross pipe. Such frame structure lowers level of a center of gravity of the vehicle, and enhances rigidity. | 03-03-2011 |
20120175863 | UNIVERSAL CHASSIS - A vehicle chassis that incorporates the engine structure, transaxle structure and a backbone structure provided as a unitary structure onto which other components of a vehicle, such as suspension, steering, body and crash absorbers may be attached. The backbone structure is a closed tubular structure in which a relatively rigid drive shaft can be supported for rotational power delivery between the engine and the transaxle. Several variations of the basic chassis embodiment are disclosed to accommodate rear wheel drive, front wheel drive, four wheel drive, as well as internal combustion, electrical and hybrid powered vehicles. Front and rear energy absorbing crash structures are rigidly fixed to front and rear sub-frames of the vehicle chassis. | 07-12-2012 |
20120223514 | WHEELCHAIR - A conveyance such as a wheelchair that includes a seat assembly and a chassis. The chassis comprises a central frame member disposed substantially along the centerline of the wheelchair. The central frame member includes portions for connecting to or supporting one or more front casters, a seat assembly, one or more drive wheel assemblies, an energy source (e.g., one or more batteries), rear anti-tip wheels, and/or at least one footplate. The central frame member is disposed substantially along the centerline of the wheelchair and structurally distributes of the weight of the seat assembly (and optionally the weight of the energy source) to the supporting drive wheels and casters. In this manner, a clean-looking, simple, and lightweight chassis structure is provided for a conveyance. | 09-06-2012 |
