Abstract

The invention relates to a bicycle freewheel. The bicycle freewheel comprises a freewheel body. The freewheel body comprises a jacket, a fly core, a jack, a jack spring and a multi-layer rolling bearing. The fly core is embedded in a mounting hole of the jacket. External teeth used for connecting with a chain are uniformly distributed on the outer ring surface of the jacket, and ratchets are uniformly distributed on the inner ring surface of the jacket. The jack is hinged on the outer ring surface of the fly core, and meshed with the ratchets. The multi-layer rolling bearing comprises an inner-layer shaft sleeve, an outer-layer shaft sleeve and at least one layer of an intermediate shaft sleeve which is installed between the outer-layer shaft sleeve and the inner-layer shaft sleeve. A rolling element is installed between every two layers of the neighboring shaft sleeves, wherein the outer-layer shaft sleeve is embedded in the mounting hole of the fly core in a mode of the rotation along with the fly core. The provided freewheel is simple in structure. Compared with a common freewheel, the rotation speed is faster while the freewheel is used as a driven wheel, and the labor is savedmore while riding by a bicycle provided with the bicycle freewheel.

Description

technical field [0001] The invention relates to the field of bicycle accessories, in particular to a bicycle flywheel. Background technique [0002] The bicycle flywheel is a wheel-shaped accumulator with a large moment of inertia installed on the rear axle of the bicycle. When the speed of the rear wheel of the bicycle increases, the kinetic energy of the bicycle flywheel increases and the energy is stored; when the speed of the rear wheel of the bicycle decreases, the kinetic energy of the bicycle flywheel decreases and the energy is released, which has an appropriate moment of inertia, storage and release The rotating member acting on the kinetic energy can not only drive the wheel forward, but also freely reverse and idle, and can receive intermittent force. [0003] However, bicycle flywheels in the prior art generally have the problem of slow rotation speed. Contents of the invention [0004] The present invention is proposed in view of the above-mentioned problems...
