Description

Driving device with clutch function Technical Field The utility model relates to the field of hand pushing equipment, in particular to a driving device with a clutch function. Background The folding handcart can be carried about when people travel, walk or shop, not only can hold all articles carried about, but also can be used for infants in different growth stages to sit, and a hand push wheelchair is also arranged for facilitating safe travel of people with inconvenient actions. At present, most hand pushing equipment such as carts, wheelchairs and the like are manually driven, the driving speed is low, people pushing for a long time are tired, in order to save effort, the driving mode is changed from manual driving to motor driving, a hub motor with a hub and a motor integrated is adopted as the motor, the input power of the motor is in linear relation with the rotating speed and the torque of the hub motor, namely, the larger the power is, the faster the rotating speed is, and the larger the torque is. Hand propelled devices generally require low speeds, however, the torque is correspondingly reduced at low speeds. While the hand pushing device needs low rotation speed and high torque when turning or climbing. Therefore, the hub motor cannot meet the requirements. In order to meet the requirements of low rotation speed and high torque, the motor adopts a gear motor combined with a speed reducer, and when the electric drive is performed, the speed reducer presents low rotation speed and high torque, so that the requirement of low-speed safe running of hand-push equipment is met.
