Chassis structure of AGV

Abstract

The invention discloses a chassis structure of AGV. The chassis structure of the AGV comprises swing driving modules and a vehicle module; the swing driving modules are in pivoted connection with thetwo sides of the vehicle frame symmetrically; each swing driving module comprises a swing arm; the swing arm is provided with a driving end; a driving wheel is arranged on the driving end; a front foot end is arranged on the swing arm; a front castor is connected with the front foot end; one side, adjacent to the vehicle frame, of the swing driving module is in pivoted connection with a swing rearaxle module; back castors are arranged at the two ends of a rear axle arm of the swing rear axle module; and the swing plane of the swing driving module and the swing plane of the swing rear axle module are vertical to each other. Through simple structural design, the AGV with low self weight can pull large load, and pulling and maintenance can be facilitated under the condition that the AGV doesnot have electricity.

Description

technical field [0001] The invention relates to an AGV chassis technology, in particular to an AGV chassis structure. Background technique [0002] In general, AGVs commonly use two-wheel differential chassis. The driving force is related to the pressure. The greater the pressure, the greater the friction with the ground. The pressure source related to the driving force is generally the preload of the elastic element in the drive module. The driving force will not change under the same conditions after design confirmation. In order to meet the requirements of large loads, the commonly used design method needs to increase the preload of the elastic elements in the drive module as much as possible, and the preload is positively correlated with the total weight of the vehicle body. Therefore, it can be seen that as the rated load increases, the vehicle weight needs to correspond The increase of excessive vehicle weight has caused various disadvantages. [0003] Chinese Patent...
