AGV driving mechanism

Abstract

The invention discloses an AGV driving mechanism which comprises a driving mechanism base and fixing plates arranged at the two ends of the driving mechanism base. Driving devices are arranged on the fixing plates. An adjusting mechanism is arranged in the position of each driving device. A driving shaft buffer device is arranged on the driving mechanism base. The AGV driving mechanism comprises the two independent driving devices, through a method of reducing the distance between two wheels, the differential speed of the two wheels with the long distance is divided into the differential speed of a plurality of sets of wheels with the small distance between every two wheels, and the vehicle steering speed problem and the miniaturization problem of the value R of the distance between every two wheels of a vehicle are fundamentally solved.

Description

technical field [0001] The invention relates to the field of AGV technology, in particular to an AGV drive mechanism. Background technique [0002] AGV has a history of more than 50 years since its invention. With the expansion of application fields, its types and forms have become various. At present, the walking mechanism commonly used by AGV is a four-wheel walking mechanism with steering wheels, which includes two driving wheels and two supporting wheels and is distributed in a diamond shape. The four-wheel walking mechanism with steering wheel is evolved on the basis of the three-wheel walking mechanism. It is equivalent to combining two tricycles together. The fulcrums of the two supporting wheels are at the apex of the isosceles triangle of the base. The front and rear wheels are both steering wheels and driving wheels. This kind of AGV car can track the trajectory of the guide line when the front and rear wheels are turning, and its maneuverability is better than ...

AI Technical Summary

Problems solved by technology

However, the walking mechanism also has the following problems: the walking mechanism AGV is not suitable for the in-situ rotation of the AGV in the intensive storage area: when the car body rotates in situ, since the supporting wheels on both sides have no driving force, the flexibility of its rotation is limited. and stability are not enough

Two-way walking AGV car, a single-drive two-way walking AGV is to install a non-rotatable drive unit at the bottom of the body, and install four universal wheels at the bottom of the front and rear ends of the body. When the AGV trolley is walking, the driving wheels drive four universal wheels. When the steering wheels move together, the trolley will travel in a serpentine route during the walking process, and the body cannot be balanced and cannot go straight straight. Compared with a single AGV under the same load, the motor power consumed is larger, and the existing technology The drive unit of this single-drive two-way AGV is fixed relative to the body. When the AGV car turns, the drive unit needs to drive the entire body to turn together, so that the required torque is too large, so that the motor power consumption is too large, and the cost Increase
