Embodiment

[0051] A kind of middle variable speed motor, refer to figure 1 and figure 2 , which includes a central axis mechanism 1, a speed change mechanism 2, a power-assisted drive mechanism 3, and a shifting drive mechanism 4; in this embodiment, the four working mechanisms are all independent modular units, and the connections between the various mechanisms are realized through transmission, which is convenient for production and assembly, as well as subsequent maintenance; where the speed change mechanism 2 is separated from the shift drive mechanism 4, the structure of the speed change mechanism 2 can be simplified; in this embodiment, a transmission mechanism 5 is also arranged between the power-assisted drive mechanism 3 and the speed change mechanism 2, Specifically, the transmission mechanism 5 is an idler wheel assembly, and the transmission mechanism 5 is used to transmit the rotating speed, which is convenient for optimizing the size and the overall layout; in other option...

Abstract

The invention discloses a centrally-mounted variable-speed motor, and relates to the field of centrally-mounted motors. According to the key points of the technical scheme, the motor comprises a center shaft mechanism, a power-assisted driving mechanism and a speed change mechanism, and further comprises a gear-shifting driving mechanism, and the gear-shifting driving mechanism comprises a rotating speed superposition execution assembly and a gear-shifting motor used for controlling the rotating speed superposition execution assembly. The gear-shifting driving mechanism and the speed change mechanism are separated and then connected in a transmission mode, meanwhile, the gear shifting driving mechanism adopts the gear-shifting motor to achieve automatic adjustment of gears and can be matched with automatic control of the motor, centralized control is achieved, operation of a rider is facilitated, and therefore the riding experience is improved.

Description

technical field [0001] The invention relates to the field of mid-mounted motors, more specifically, it relates to a mid-mounted variable-speed motor. Background technique [0002] At present, the center-mounted power-assisted bicycle motors on the market are mainly ordinary deceleration center-mounted motors, which cannot realize gear shifting and shifting, and bicycle shifting still depends on its own bicycle gear switcher. [0003] If the user wants the power of the motor and the smooth speed change, two systems of the bicycle gear switch and the deceleration center motor are needed. But the two systems are not only difficult to match, but also relatively complicated to assemble the bicycle. [0004] The existing authorized notification number is the Chinese patent of CN104953759B, which discloses a central motor with a variable reduction ratio for an electric bicycle, but the central motor can only realize two different reduction ratios. [0005] The existing authorized...
