Title:
ACTUATOR AND GEAR SHIFTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/216247
Kind Code:
A1
Abstract:
An actuator comprises: a speed reduction mechanism (9), a motor (10) and a rotating hub (11). The speed reduction mechanism (9) is rotatably connected to the motor (10) and the rotating hub (11) respectively. The outer peripheral surface of the rotating hub (11) is provided with a groove having an inclination angle in a circumferential direction. The rotating hub (11) converts rotational motion in the circumferential direction into linear motion by means of the groove so as to output power. The speed reduction mechanism (9) and the motor (10) are at least partially integrated inside the rotating hub (11). The motor (10) supports the rotating hub (11). In the actuator, the speed reduction mechanism and the motor are integrated inside the rotating hub to save the arrangement space of the actuator. Moreover, the transmission efficiency is higher, a large speed ratio can be achieved in a limited space, and at the same time large output power is provided. Further disclosed is a gear shifting system.
