摘要:
Speiche (4), Rad und Verfahren zur Herstellung einer Speiche, für Fahrräder, wobei die Speiche wenigstens zwei Speichenkörper (9) umfasst. An jedem Speichenkörper (9) sind Speichenenden (10) zur Befestigung an einer Felge (3) bzw. einem Nabenkörper (2) vorgesehen. Jeder Speichenkörper (9) besteht aus einem Faserverbundwerkstoff. Dabei sind die zwei Speichenkörper (9) einstückig verbunden und kreuzen sich in einer Ebene. Jeder Speichenkörper umfasst jeweils eine Vielzahl von Fasern (42).
摘要:
A spoke (1501r) for a bicycle wheel having an intermediate portion (154) of greater cross-sectional area than its end portions, and a method for its manufacture are disclosed.
摘要:
A device, eg ball castor (11), providing multi-directional movement comprising a housing (13) having at least one rolling member located partially their. eg ball (12) Bearing means comprising sets of ball bearings held in annular races transmit the load of a trolley, etc carried by the device to ball (12) and also act to centre ball (12). A brake having pad (22) is urged against the top of ball (12) by a screw or spring to resist rolling movement of ball (12).
摘要:
A balance weight comprising a cartridge having at least one interior chamber, the interior chamber at least partially filled with a flowable balance media, and wherein the cartridge is longitudinally arcuate, at least when attached to a wheel, about an angle of up to 180 degrees or less. The balance weight provides a balanced tire in the new or just balanced condition and helps retain the balance under changes in at least one operational characteristic of the tire/wheel assembly.
摘要:
An anti-friction bearing interposable at the crossing-over point between two spokes (5a, 5b) of a bicycle wheel comprises a body (6) having a through hole (7), with a completely closed continuous part (8), and giving out onto two opposite ends (9) of the body (6) to receive through it one of the two spokes. The body (6) further includes a portion of external surface (10) in contact with the other spoke.
摘要:
An inner race 5 is retained by a crimped portion 30, so that a pre-load is applied to rolling elements 6. A bearing unit for wheel support 1 is connected to a constant velocity joint 2 through tightening of a nut 24. By regulating the tightening force of the nut 24, at the area of contact between the inside end of the crimped portion 30 and the outside end of the outer ring of the constant velocity joint 14, the load per unit length is controlled up to 125 N/mm, or the surface pressure is controlled up to 1.5 x 10 8 Pa. Consequently, a bearing unit for wheel support is realized at a low cost with the pre-load securely applied, preventing unpleasant noise from occurring during operation, andpreventing play due to plastic deformation.
