Abstract:
Disclosed herein is structure for constraining the locations of three IVCs in a two-wheel vehicle suspension linkage. In some embodiments, the suspension linkage includes a first body; a second body; and a third body operatively coupled with one another. The first body includes a jointed connection with the second body defining an IVC[3][6], and a jointed connection to the third body defining an IVC[3][4]. The second body is operatively coupled to the third body defining an IVC[4][6]. The first body includes a first aperture, having a common axis with the IVC[3][4]. The second body includes a second aperture having a common axis of the IVC[3][6]. The IVC[3][4], the IVC[3][6] and the IVC[4][6] are located within one of the first aperture or the second aperture. The IVC [3][4], the IVC[3][6], and the IVC[4][6] are located in different positions from one another.
Abstract:
A pedal-drivable and electrically-drivable vehicle (10) comprising a chassis (12), wheels (14, 16), a pedal mechanism (18), an electric motor (20), and a battery (22). The chassis (12) includes a back chassis-portion (30) having a trailing part (38) extending in a first plane (P1) and a leading part (36) and an intermediate chassis-portion (32) extending in a second plane (P2) which is offset from the first plane (P1). The trailing part (38) and the intermediate chassis-portion (32) are interconnected by the leading part (36) which tapers with at least one compound bend (48a) from the trailing part (38) to the intermediate chassis-portion (32) so as to provide integrated suspension between a wheel (16) and the intermediate chassis-portion (32).
Abstract:
A joint assembly including a housing including an inner diameter portion having a tapered surface; and at least one shaft having an outer diameter portion having a tapered surface that is complementary in shape to the inner diameter portion of the housing, where the shaft is adapted to rotate relative to the housing, and where the frictional fit is adjustable by modifying the axial position of the shaft relative to the housing.
Abstract:
Disclosed is a vehicle comprising a frame component having an adjustable physical property; and a controller configured to receive data relating to the vehicle in use and, based on received data, determine a value of the physical property of the frame component. A method, a computer program and a control system are also disclosed.
Abstract:
The present invention relates to a joining structure for a frame of a bicycle. The present invention provides a joining structure for a frame of a bicycle having a main frame including a horizontal tube, a vertical tube, an inclined tube, a pair of seat stay tubes and a pair of chain stay tubes. One side of the horizontal tube and one side of the inclined tube are joined to a head tube cell. The other side of the horizontal tube, one side of the vertical tube and one side each of the pair of seat stay tubes are joined to a seat tube cell. The other side of the vertical tube, the other side of the inclined tube and one side each of the pair of chain stay tubes are joined to a bottom tube cell. The other side of the pair of seat stay tubes and the other side of the pair of chain stay tubes are joined to a drop-out tube cell. The abovementioned tubes and cells are joined by a joining member through a press-fitting process. The joining member is a hollow cylinder having a stopper protrusion formed at the center of an outer surface thereof. A plurality of slits is formed into a predetermined length inwardly from both ends of the joining member, respectively, extending from the center of the stopper protrusion. Each of the slits has an end with a through-hole. A plurality of sawteeth protrusions are formed inwardly from the both ends of the joining member, respectively. The sawteeth protrusions are formed at the surfaces between the stopper protrusion and the slits with through-holes, respectively. The present invention eliminates the necessity of a welding process to prevent bicycle accidents caused by faulty welding. The elimination of a welding process results in an economical advantage in a manufacturing process, and eliminates the need for expensive welding equipment. The present invention finishes a painting process for joining members such that the joining members have a variety of patterns prior to an assembly process, thus achieving an aesthetic enhancement. The present invention utilizes not only the same type of metals but also metals of different types, synthetic resins or a variety of natural materials, thus obtaining a variety of designs and an aesthetic enhancement. The present invention enables the assembly of the bicycle frame and the production of the bicycle having an independent model design.
Abstract:
A connecting element, particularly for connecting rear forks, also known as monostays, made of carbon to bicycle frames. The connecting element is constituted by a first insert (6) and a second insert (7) which are mutually detachably associable at a first end (8a, 8b) by way of mechanical connection element (12). The first (6) and second (7) inserts are respectively associated, at a second end (18a, 18b), advantageously by way of adhesives, with the stem (4) of a carbon monostay (3), and are associable with, or rigidly coupled to, a tubular extension (2) of the frame (1).
Abstract:
A scooter (1) is arranged to be foldable about a hinge arrangement (40), wherein the hinge arrangement is positioned substantially midway between a front wheel (2) and a rear wheel (3).
Abstract:
A vehicle frame assembly has a first frame member defining a first frame member axis and a slot and having a first frame member connection portion adjacent the slot. A second frame member defining a second frame member axis has a projection and a second frame member connection portion adjacent thereto. The projection is received in the slot. The first frame member connection portion is connected to the second frame member connection portion to form a connection region in which the second frame member axis is disposed at a non-zero angle to the first frame member axis in the connection region. The method of assembling the frame includes inserting the projection into the slot, contacting the connection portions to each other to form the connection region with the members being positioned for connection with their axes disposed at a non-zero angle to each other, and connecting the connection portions.
Abstract:
A bicycle frame (300) includes a seat tube (308) and a top tube (324). A coupling device (350) flexibly couples the top tube (324) to the seat tube (308) such that the top tube (324) is able to move in a vertical direction with respect to the seat tube (308).
