Steering wheel structure and AGV using steering wheel

Abstract

The invention provides a steering wheel structure, and belongs to the field of AGVs. The steering wheel structure is characterized by including a driving wheel, a supporting plate, a rotation supporting bearing, a steering fixing disk, a steering gear and a steering motor, wherein the rotation supporting bearing includes outer teeth and an inner rotating disk, and the outer teeth can rotate relative to the inner rotating disk around the axis of the inner rotating disk; the inner rotating disk is fixedly connected with the steering fixing disk arranged at the top of the inner rotating disk, andthe steering fixing disk is used for being connected with a vehicle body; the steering gear is arranged on one side of the rotation supporting bearing, and the outer teeth of the rotation supportingbearing mesh with the steering gear; the steering motor driving the steering gear to rotate is arranged at the bottom of the steering gear and fixedly connected with the steering fixing disk, and thesupporting plate is arranged at the bottom end of the rotation supporting bearing and is fixedly connected with the outer teeth; and the driving wheel and an AGV using a steering wheel are connected to the supporting plate. According to the steering wheel structure, the turning radius can be effectively reduced, and the requirement of a small-type AGV can be met.

Description

technical field [0001] The invention relates to the field of AGVs, in particular to a steering wheel structure and an AGV using the steering wheel. Background technique [0002] In the current stage of the AGV industry, the rudder wheel drive is more and more widely used because of its advantages such as forward and backward walking, side shifting, and in-situ rotation. In the prior art, the Chinese invention patent with application number 201410112538.1 discloses a steering wheel driving device, which includes a steering motor mounting plate, a steering motor located under the steering motor mounting plate, and a drive wheel assembly located below the steering motor mounting plate 1. The pinion gear connected to the steering motor, the bull gear matched with the pinion gear and the steering bracket connected with the bull gear; The wheel shaft; the steering motor drives the pinion to rotate, the pinion drives the large gear to rotate, and the large gear drives the drive wh...

Problems solved by technology

However, in the application process, the rotation radius of the steering wheel is too large, and the steering wheel takes up too much space in the overall design of the AGV. For example, the radius of the steering wheel with the smallest rotation radius in China has reached 290mm, and the height is about 190mm, which is not convenient for the design of small AGVs.
