Disclosed herein are systems and techniques for producing complex components using a reinforced thermoplastic material. The complex components can include contoured or curved outer surfaces, and in some cases define a cavity. In certain examples, one or more thermoplastic materials are arranged to form a wheel component, such as that adapted to define a rim of the bicycle. Thermal bonding can be used to join multiple reinforced thermoplastic materials to one another in order to form a cavity of the wheel component or other complex shape. In certain examples, a portion of a tooling assembly can be pressurized to maintain a shape of the cavity during thermal bonding and cooling. This can remove the need for a sacrificial bladder or other structure that would maintain the shape of the cavity, allowing for a seamless final component, optionally absent indicia of bladder exit or other seams. 1.

COMPOSITE FIBER BICYCLE WHEELS

Номер: US20160144658A1
Автор: HJERTBERG Eric, Kismarton Max U., Lobisser G. Kyle
Принадлежит:

Carbon fiber bicycle wheels are formed from parts cut from carbon fiber cloth and then joined together to form a rim, sidewalls, spokes, flanges and a center tunnel on which the flanges are mounted. The parts are then assembled, bonded together, and cured to form a wheel. During assembly, the spokes and the wheel are placed in tension by moving the flanges outwardly on the center tunnel after assembly and then bonding them in place to stiffen and strengthen the wheel. The spokes of the drive side of the rear wheel are specially shaped to accommodate torque transfer forces generated by pedaling.

The present application provides a composite wheel, including spokes, a rim and a central disc, one end of each spoke being connected to the central disc and the other end of each spoke being connected to the rim, each spoke includes a spoke skeleton and a spoke shell, and the spoke skeleton is wrapped by the spoke shell; and the spoke shell is made of plastic, rubber, nylon or resin. The technical solution of the present application brings the beneficial technical effects of overcoming the contradiction between the pursuit of the artistic design effect of the wheel and the pursuit of the lightweight of the wheel and meeting the strength requirement of the wheel. 1. A composite wheel , comprising spokes , a rim and a central disc , one end of each spoke being connected to the central disc and the other end of each spoke being connected to the rim , wherein each spoke comprises a spoke skeleton and a spoke shell , and the spoke skeleton is wrapped by the spoke shell; and the spoke shell is made of plastic , rubber , nylon or resin.2. The composite wheel according to claim 1 , wherein the spoke skeleton has a T-shaped cross section or π-shaped cross section claim 1 , top transverse edge of T-shaped spoke skeleton or π-shaped spoke skeleton is disposed close to outer surface of a hub claim 1 , and the longitudinal edge of T-shaped spoke skeleton or π-shaped spoke skeleton is disposed to point to inner cavity of the hub.3. The composite wheel according to claim 2 , wherein the top transverse edge of T-shaped spoke skeleton or π-shaped spoke skeleton has a thickness of 6-8 mm and the longitudinal edge has a thickness of 3-5 mm.4. The composite wheel according to claim 2 , wherein the spoke skeleton is in one spoke claim 2 , the top transverse edge of T-shaped spoke skeleton or π-shaped spoke skeleton has a width of 22-45 mm and the longitudinal edge has a width of 25-40 mm.5. The composite wheel according to claim 1 , wherein the spoke skeletons are integrated with the ...
