Singe-driving and double-direction type AGV

Abstract

The invention relates to the technical field of automatic guided vehicles, in particular to a single-driving and double-direction type AGV. The single-driving and double-direction type AGV comprises a vehicle body, a navigation sensor, a controller, a driving assembly, a first universal wheel set and a second universal wheel set, the navigation sensor and the controller are arranged on the vehicle body, the driving assembly is arranged below the vehicle body, and the first universal wheel set and the second universal wheel set are arranged at the bottom of the vehicle body in a front-and-back opposite mode. The driving assembly is connected with the controller. The single-driving and double-direction type AGV further comprises a directional wheel arranged at the bottom of the vehicle body and a switching mechanism connected with the directional wheel. The switching mechanism is connected with the controller, and the switching mechanism is used for folding or expanding the directional wheel and expands the directional wheel to the rear end of the vehicle body according to the moving direction of the single-drive and double-direction type AGV. According to the single-driving and double-direction type AGV, due to the fact that the directional wheel and the switching mechanism are arranged on the vehicle body, the directional wheel can be expanded to the rear end of the vehicle body according to the moving direction of the AGV, and therefore the AGV can walk stably, the power consumption of a motor is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic guided transport vehicles, in particular to a single-drive bidirectional AGV. Background technique [0002] AGV (Automated Guided Vehicle, AGV), also known as AGV unmanned vehicle, refers to a transport vehicle that is equipped with an automatic navigation device and can walk according to a prescribed guiding route, and can realize unmanned transportation operations in industrial applications , and use a rechargeable battery as its power source. [0003] At present, the walking modes of AGV are mainly one-way walking and two-way walking. The one-way walking AGV trolley is equipped with two universal wheels at both ends of the front end of the body, two directional wheels at the rear end, and a driving device under the middle of the body. The advantage of this one-way AGV is that the body is stable and the turning radius Wait a minute. AGV trolleys with two-way travel, the traditional technolo...

AI Technical Summary

Problems solved by technology

AGV trolleys with two-way travel, the traditional technology is to install two drive units at the bottom of the body, although this AGV can achieve two-way travel, but in view of the two drive units on the body, the structure is complex and the manufacturing cost is high; another single The AGV with two-way driving is installed with a non-rotatable drive unit at the bottom of the body, and four universal wheels are installed at the bottom of the front and rear ends of the body. When the AGV trolley is walking, the driving wheel drives the four universal wheels to move together. It will travel in a serpentine route, the body cannot be balanced and cannot go straight straight. Compared with the one-way AGV under the same load, the motor power consumed is larger, and the single-drive two-way AGV in the prior art has a The drive unit is fixed relative to the body. When the AGV trolley 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 increases
