自行车无级变速(国外英文资料) 01, the utility model discloses a continuously variable transmission, including sprocket, sprocket shaft connected by a one-way clutch and the chain wheel; a sleeve is sheathed in the sprocket shaft; one end of the sleeve is provided with a conical wheel shaft connected with the ring gear, the wheel shaft extension to the tapered inner gear ring; sprocket shaft located in the conical inner gear ring is arranged on the small sprocket, the small sprocket through the drive chain is meshed with the bevel gear shaft is arranged in the conical inner gear ring; in the transmission chain are sheathed outside the elastic supporting tube. The utility model has the advantages that the automatic speed change can be realized according to the moment of rotation when riding a bicycle. When the torque on the chain wheel is larger, the sprocket shaft drives the bevel gear to move toward the big diameter end of the cone inner ring gear, and the transmission ratio of the bevel gear and the conical inner gear ring is lowered, and vice versa. Thus, the purpose of automatic stepless regulation of the speed of the wheel shaft connected with the conical inner ring is achieved. Principal claim: A continuously variable transmission, which is characterized by comprising a sprocket (1), through the one-way clutch (11) and (1) the chain sprocket shaft connected to the (2); the chain wheel (2) is sleeved on the sleeve (3); the sleeve (3). One end is provided with a wheel shaft (10) connected to the cone ring gear (4), the sprocket shaft (2) extending to the cone ring gear (4); in the taper ring gear sprocket (4) in the shaft (2) is arranged on the small sprocket (5) and the small sprocket through the drive chain (5) and (6) is arranged in the taper ring gear bevel gear (4) in the shaft (7) is engaged in the transmission chain; (6) coat with elastic supporting tube. 02, the utility model belongs to a bicycle, particularly relates to a stepless variable speed bicycle, a front wheel
