Problems solved by technology

[0004] Due to the structure and space constraints of the two-stage reduction gear, the clutches that can be selected are usually small in size. At the same time, because clutches are commonly used as standard parts, and the smaller the size, the smaller the load torque. Therefore, space constraints are often not conducive to the improvement of the motor's power boosting capability.

Abstract

The invention discloses a middle driving device which comprises a shell, a motor arranged in the shell, a speed reducing mechanism, a middle shaft and a chain wheel device; the speed reducing mechanism is in transmission connection with the motor. The middle shaft is used for being connected with a treading device and is rotationally arranged in the shell; a first clutch is included, wherein One end of the first clutch is connected with the output end of the speed reducing mechanism, and the other end of the first clutch is connected with the chain wheel device; the first clutch has a transmission state and a disengagement state, and the chain wheel device is connected with the middle shaft through a second clutch so that the middle shaft can drive the chain whell device to rotate; in thepower-assisted working mode, the first clutch is in transmission connection with the output end of the speed reducing mechanism and the chain wheel device, so that the output end transmits power to the chain wheel device; and in the non-power-assisted working mode, the first clutch disconnects the output end of the speed reducing mechanism from the power of the chain wheel device. The middle driving device is more portable and labor-saving when people step on the bicycle. The invention further discloses a bicycle comprising the middle driving device.

Description

technical field [0001] The invention relates to the technical field of vehicle design, and more specifically, relates to a mid-drive device. In addition, the present invention also relates to a bicycle comprising the above-mentioned intermediate drive device. Background technique [0002] In the prior art, the central driving device of the power-assisted bicycle generally includes a motor, a first-stage reduction gear and a second-stage reduction gear connected to the motor, and the output gear of the second-stage reduction gear finally drives the crankshaft to rotate, thereby powering the bicycle. . [0003] On the transmission path from the motor to the crankshaft, a clutch is generally provided between the first-stage reduction gear and the second-stage reduction gear. Disconnect the connection between the motor and the first-stage reduction gear, thereby realizing the function of the power-assisted bicycle as an ordinary bicycle. [0004] Due to the structure and spac...
