Driving wheel and AGV

Abstract

The invention provides a driving wheel and an AGV. The driving wheel comprises an input shaft, the input shaft is provided with a plurality of eccentric structures, each eccentric structure is provided with an outer gear, the outer gear is sleeved with a hub, the inner side of the hub is provided with a circle of inner teeth capable of being meshed with the outer teeth of the outer gear. The driving wheel further comprises a support assembly, the support assembly comprises a plurality of pin shafts, a plurality of pin holes distributed in the circumferential direction are formed in each outergear, the pin shafts penetrate through the pin holes of the outer gears, and the outer gears do translational motion with the mass center as the circumferential track under the action of the input shaft and the pin shafts. The outer teeth of the outer gears shift the inner teeth of the hubs to drive the hubs to rotate. According to the driving wheel and the AGV, driving, transmission and braking are integrally designed, the arrangement structure is compact, and the overall size of the driving wheel is greatly reduced; a brake is connected with the input shaft, and the braking torque is small.

Description

technical field [0001] The invention relates to a driving wheel and an AGV vehicle, in particular to an AGV driving wheel and an AGV vehicle integrating drive transmission and braking. Background technique [0002] The AGV trolley is equipped with an automatic guidance device, can travel along a prescribed route, has safety protection functions and is already in use. Since a driver is not required in industrial applications, its travel route and behavior can be set and controlled by a computer, etc. , has the characteristics of high efficiency, speed, automation and safety, and is widely used in logistics, warehousing and other industries. [0003] The AGV trolley is mainly driven by the driving wheel, and most of the driving structures on the market use the structure of the motor accelerator and reducer externally connected to the wheel hub. Since the AGV drive wheel requires small size and large load, the drive components are required to be small in size, exquisite in str...

AI Technical Summary

Problems solved by technology

Usually, the speed of the motor is very high, so it is difficult for the existing transmission structure to ensure a high transmission ratio and high transmission torque while ensuring a small volume.

Most of the current structure is that the motor and the reducer are connected to the hub in series, and the overall volume of this structure is very large.

[0004] And with this structure, one end of the reducer is input and the other end is output. The brake can only be placed at the output end or the tail of the motor; if it is placed at the output end, the demand for braking torque is relatively large; if it is placed at the tail of the motor, then further increase in volume
