Problems solved by technology

Most of the existing AGV trolleys that can move in all directions adopt omnidirectional wheels or Mecanum wheels to achieve all-round movement and rotation to meet industrial needs, but there are great limitations in actual use.
Mecanum wheels are expensive, difficult to process, and have a shorter service life than traditional rubber wheels; the structural design of the omnidirectional wheel determines that it cannot be used in places where there are many debris such as hair and dust particles. When the wheel is entangled by hair Or if it is stuck by particles, the force direction will deviate from the theoretical force direction, causing the AGV to move in an abnormal direction or rotate, and in severe cases, it will derail. It is used on terrain; two driving wheels plus two universal wheels, the universal wheels can be used as a support point, and there will not be much friction with the ground when the car rotates, but this design determines that the car's ability to overcome obstacles is very poor. When the universal wheel as a driven wheel encounters a large obstacle, the driving wheel may be suspended in the air. At this time, the AGV car loses its driving force and cannot move forward over the obstacle.

Abstract

The invention provides a guiding vehicle. The guiding vehicle comprises a wheel system, a first transmission mechanism and a second transmission mechanism. The wheel system comprises a first wheel setand a second wheel set. The first transmission mechanism comprises a steering motor, a first gear and a second gear, and the steering motor drives the first gear and the second gear to rotate in opposite directions; the second transmission mechanism is mechanically connected between the first transmission mechanism and the wheel system, the first gear drives the first wheel set to rotate throughthe second transmission mechanism, and the second gear drives the second wheel set to rotate through the second transmission mechanism. The steering motor drives the first gear and the second gear torotate in the opposite directions and drives the first wheel set and the second wheel set to rotate correspondingly, omnidirectional movement of the guiding vehicle is achieved, and the guiding vehicle is high in obstacle crossing and climbing capacity and high in adaptability to a construction site.

Description

technical field [0001] The invention relates to the technical field of construction machines, in particular to a guiding vehicle. Background technique [0002] Mobile AGV (Automatic Guided Vehicle, automatic guided vehicle) is used as a transportation tool in various fields. Most of the existing AGV trolleys capable of omnidirectional movement use omnidirectional wheels or Mecanum wheels to achieve omnidirectional movement and rotation to meet industrial needs, but there are relatively large limitations in actual use. Mecanum wheels are expensive, difficult to process, and have a shorter service life than traditional rubber wheels; the structural design of the omnidirectional wheel determines that it cannot be used in places where there are many debris such as hair and dust particles. When the wheel is entangled by hair Or if it is stuck by particles, the force direction will deviate from the theoretical force direction, resulting in abnormal movement direction or rotation ...
