Problems solved by technology

[0002] In the prior art, there are the following problems in the riding of electric mopeds. Since the speed increases continuously during the pedaling process, the pedaling frequency will increase. When the speed increases to a certain level, empty pedaling will occur. At this time It will bring great discomfort to the rider. At the same time, pure electric vehicles have poor battery life due to the full use of battery functions.

Abstract

The invention provides a stepless variable speed transmission device and an electric booster vehicle applying the stepless variable speed transmission device. The stepless variable speed transmissiondevice includes a planetary variable speed device. The planetary variable speed device comprises a sun wheel, a planetary frame, a planetary gear, a planetary tooth ring and a connecting plate. The stepless variable speed transmission device has the beneficial effects that the stepless variable speed transmission device can adjust the rotating speed of the sun wheel to realize the change of the gear, because the rotating speed is a variable that can be changed continuously, and stepless variable speed can be achieved; and the pedal feel can be made to be smoother, a certain pedal frequency andpedal strength are maintained, and better experience is brought to a rider.

Description

technical field [0001] The invention relates to the field of electric bicycle accessories, in particular to a continuously variable transmission device and an electric bicycle using the device. Background technique [0002] In the prior art, there are the following problems in the riding of electric mopeds. Since the speed increases continuously during the pedaling process, the pedaling frequency will increase. When the speed increases to a certain level, empty pedaling will occur. At this time It will bring great discomfort to the cyclist. At the same time, pure electric vehicles have poor endurance due to the full use of battery functions. Contents of the invention [0003] The purpose of the present invention is to provide a continuously variable transmission device that can improve riding experience and an electric bicycle using the device. [0004] Technical scheme of the present invention is: [0005] A continuously variable transmission device, including a planeta...
