WIPO Patent Application WO/2017/020870
Kind Code:
A1
Abstract:
A wheel comprising a wheel hub (1), a spoke (2), a braking element (4), and a fastening connector component comprising a threaded rod (5) and a rotation-stopping sleeve (7). The threaded bolt fixes together the wheel hub, the spoke, and the braking element. The spoke is provided with a first rotation-stopping hole (28). Provided on the wall of the first rotation-stopping hole and/or the rotation-stopping sleeve is an extraction structure (20) for extracting the rotation-stopping sleeve mounted on the exterior of a fastening nut (6) and within the first rotation-stopping hole. The rotation-stopping sleeve is mounted on the exterior of a rotation-stopping resistant part (58) of the threaded rod and within the first rotation-stopping hole. A third rotation-stopping part (64) of a first rotation-stopping through hole (63) fits a fourth rotation-stopping part (61) of the rotation-stopping resistant part to restrain rotation of the threaded bolt relative to the first rotation-stopping sleeve. A second rotation-stopping part (65) on the periphery of the rotation-stopping sleeve fits a first rotation-stopping part (74) of the first rotation-stopping hole to restrain rotation of the first rotation-stopping sleeve relative to the spoke. The threaded bolt is non-rotatably mounted together with the spoke. The threaded connection does not come loose due to rotation in reverse. Extraction of the rotation-stopping sleeve is convenient.
