Patent number: 8393448Abstract: A spring fork, in particular for bicycles, with a suspension system and a hydraulic damping system, includes a compression stage damping system (6) for a spring deflection process and a traction stage damping system (5) for a rebound process. At least one piston (3, 16, 27) is provided, which is located in the cylinder (2), and at least one connecting channel (17, 17a) is provided which connects the cylinder chambers located on both sides of the piston and is intended for the overflow of hydraulic oil (21). The compression stage damping system (6), which is activated during the spring deflection process, can be blocked by closing the connecting passage (lockout). At least with the compression stage damping system (6) blocked and, if appropriate, also with the traction stage damping system (5) also blocked, a bypass channel (11, 20, 20a) which has a reduced cross-section in comparison to the connecting channel (17, 17a) is opened.Type: GrantFiled: February 23, 2007Date of Patent: March 12, 2013Assignee: Gustav Magenwirth GmbH & Co.

Publication number: 20110089661Abstract: The invention relates to a bicycle axle assembly comprising an axle formed as a carrier part for a hub, a clamping device for clamping the bicycle axle assembly in a bicycle wheel axle holder, and a stop device formed to secure the axle of the bicycle axle assembly in the axial direction in the clamped state of the clamping device. The stop device has a stop member that comprises a stop of the stop device. The stop is springy in the radial direction. The bicycle axle assembly is formed such that the stop, which is springy in the radial direction, secures the axle in the axial direction in the clamped state of the clamping device and releases the axle in the axial direction in the released state of the clamping device.Type: ApplicationFiled: December 17, 2010Publication date: April 21, 2011Inventor: Reiner Künstle

Patent number: 7810615Abstract: A brake disk for a disk brake, in particular, for motor cycles or bicycles, includes a brake band of a first material which has a high heat resistance and an inner part (20) of a second material which has a lower density than the first material. The brake band and the inner part (20) each have a plurality of extensions, which in each case are arranged in pairs bordering one another. A plurality of connecting elements connect the brake band (10) to the inner part (20) by being received in recesses (13, 23) formed in the extensions. Thus, a divided brake disk has little deformation or wear in the region of the connection between the brake band and the inner part in combination with a low weight. Specifically, the recess (23) is formed in such a way that the connecting line (51) between the ends of the recess (23) is at an angle ? of from 15 to 85° to the tangential direction (50).Type: GrantFiled: January 14, 2005Date of Patent: October 12, 2010Assignee: Gustav Magenwirth GmbH & Co.
