Abstract:
A chain sprocket comprises a sprocket body, wherein the sprocket body is provided thereon with a plurality of gears distributed along the circumferential direction of the sprocket body, the gears are used to engage with a chain, the gears are provided thereon with a magnetic structure, and the magnetic structure is used to adsorb the chain so as to prevent the chain from coming off of the chain sprocket. A bicycle, comprising a vehicle frame, a front wheel, a rear wheel, a chain, and the chain sprocket, wherein the chain sprocket is disposed on the vehicle frame, the front wheel and the rear wheel are connected onto the vehicle frame, and the chain cooperates with the chain sprocket to transmit pedaling power to the rear wheel such that the bicycle walks. Compared to the prior art, the present chain sprocket and the bicycle having the chain sprocket effectively prevent problems such as the disengagement of a chain and the like by means of disposing a magnetic structure on the chain sprocket and the magnetic force generated by the magnetic structure adsorbing the chain onto the chain sprocket, and the chain and the chain sprocket cooperate more closely therebetween under the action of the magnetic structure, such that the precision of transmitting power is higher and the efficiency is better.
