A propulsion assist device connected to a manual wheelchair to provide driving force is disclosed. The propulsion assist device provides sufficient driving force and braking force while using the motor by the self-energizing effect. The propulsion assist device can be easily connected to manual wheelchairs without the need for bending over. The self-energizing effect is provided in a mechanical way, and the risk of failure is low due to the simple structure of the device.The propulsion assist device is economically priced, enabling the elderly and disabled to improve their self-esteem as members of society and engage in safer and more active social activities.
