Abstract
The utility model relates to a device for adjusting bottom bracket parts of a bicycle. A swing arm is disposed on a bicycle frame, and the bottom bracket parts, i.e., a treading apparatus and a main fluted disc of a first transmission device, are disposed at an outer end of the swing arm. An inner end of the swing arm is movably pivoted on the bicycle frame via a pivot so as to enable an outer end to be adjustable in a swinging manner back and forth, and the pivot for locating the inner end of the swing arm is disposed coaxially with a linkage fluted disc of the first transmission device and a main fluted disc of a second transmission device. Positions of the bottom bracket parts disposed on the swing arm change as the swing arm is adjusted in a swing manner for locating, thereby enabling a rider to operate the treading apparatus from different angles and positions, and achieving an effect of distinctive, changeable, diverse and interesting operating and riding forms. Moreover, the swing arm, the linkage fluted disc of the first transmission device and the main fluted disc of the second transmission device are disposed coaxially such that smooth power transmission and bicycle body movement effects are not restrained by the swing adjustments of the swing arm at all.
Description
Technical field
The utility model is the main shaft element adjusting device of relevant a kind of velocipede, particularly arrange simply about a kind of, operate simple and easy, convenient, can make the unusual and rich variability of velocipede tool, diversity and interesting operation and the form effect of travelling, and the utmost point accords with the main shaft element adjusting device of the velocipede of actual applicability, desirability and progressive.
Background technology
General velocipede (such as bicycle) is trampled the operation that drives, mainly be to be installed on main shaft element (Bottom Bracket parks) at vehicle frame, and be installed at main shaft element place and trample device and driving device, wherein, this is trampled device and generally includes again the crank that is installed in main shaft and the pedal that is installed in crank; This driving device generally include again the fluted disc that is installed in main shaft and be connected in fluted disc and wheel between Transmissions such as interlock fluted disc, driving band (chain); Generally, by rider's both feet the pedal of trampling device is trampled running, this driving device just can be converted to propulsive effort with pedal force and transfer to axletree, wheel can smooth and easy lift-over be driven move car body to advance.
