Problems solved by technology

In this arrangement, if the turning angle is too large, the tire assembly will interfere with the bridge body, thereby limiting the range of turning angles. Generally, forklifts cannot turn in situ if they are below 90°.
[0004] Therefore, the current four-point forklift has the problems of small turning angle and large turning radius.

Abstract

The invention discloses a four-fulcrum electric forklift steering system and method applying a novel steering mode, and relates to the technical field of steering systems.The steering system comprisestwo front wheels, two rear wheels and a steering axle assembly, the steering axle assembly comprises an axle frame, a steering knuckle, a main pin and a supporting piece, and each front wheel is connected with a walking motor; the two ends of the bridge frame are each rotationally connected with a main pin, and the central axis of each main pin is a vertical axis. Each main pin is driven by a steering knuckle to rotate, and the main pins and the steering knuckles are all located above the rear wheels; each main pin is fixedly connected with a hub shaft of a rear wheel through a supporting piece. The four-fulcrum electric forklift can have a large rotating angle range and even can rotate in situ, and therefore the maneuverability and trafficability of the four-fulcrum forklift are enhanced.

Description

technical field [0001] The present application relates to the technical field of steering systems, in particular to a steering system and method for a four-point electric forklift using a new steering mode. Background technique [0002] Forklifts play a very important role in the logistics system of enterprises and are the main force in material handling equipment. Especially with the rapid development of world economy, the material handling of most enterprises has been separated from the original manual handling, replaced by the mechanized handling of forklifts. During forklift operation, steering is an action that is frequently operated. [0003] See figure 1 At present, the traditional four-point electric forklift is single-drive, one motor and one gearbox drive two tires to rotate, the bridge frame of the steering bridge is located between the two tires, and the steering knuckle is close to the hub. In this structure, although the drive axle contains a differential th...
