Problems solved by technology

[0003] The multi-axis steering system adopted by the existing trucks is set to a simple mechanical front and rear steering trapezoidal structure. The disadvantage is that there is no steering sensor and micro-electronic controller, the steering accuracy is low, and it is not easy to control; and the space position of the vehicle itself is strict. Large body, difficult to use in narrow spaces

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0022] like figure 1 A decentralized power steering system for a multi-axle load-carrying vehicle shown, figure 1 Only half of the steering system is shown in the diagram, and the other half is arranged symmetrically along the centerline of the frame. The steering system includes a steering mechanism 10 and a power mechanism 20, wherein:

[0023] The steering mechanism 10 includes two rows of left and right steering wheel shafts 1 installed on the bottom of the vehicle frame along a straight line, and a first steering arm 11 connected to the steering wheel shaft 1. Two adjacent first steering arms 11 are hinged by steering rods 2. .

[0024] In this embodiment, the steering wheel shafts 100 in the left and right rows of steering wheel shafts 1 are respectively connected to the first steering oil cylinder 31 through the second steering arm 12; the steering ...

Abstract

The invention relates to a multi-axle dispersed power steering system for a load-carrying vehicle. The steering system comprises a steering mechanism and a power mechanism, wherein the steering mechanism comprises left and right rows of steering axles which are arranged at the bottom of a frame along a straight line, and first steering arms connected to the steering axles; two adjacent first steering arms are connected through a steering pull rod; at least two steering axles in the left and right rows of steering axles are connected with steering oil cylinders through second steering arms; and a steering unit consists of at least two steering oil cylinders which are symmetrically arranged in the left and right rows, and the steering axles connected with at least two steering pull rods. The steering system has the advantages that: power is dispersed; applied force output by the steering oil cylinders is more reasonable; the width and self weight of the vehicle are reduced, and the bearing capacity of the vehicle is improved; the deviation and abrasion of tires are reduced, the service life of the tires is prolonged, and cost is saved; the steering maneuverability and accuracy of the vehicle are improved, and the like.

Description

technical field [0001] The invention relates to a decentralized power steering system of a multi-axle load vehicle. Background technique [0002] Due to the limitations of its functions, trucks are relatively bulky, and their steering system is an important indicator to measure their performance. [0003] The multi-axis steering system adopted by the existing trucks is set to a simple mechanical front and rear steering trapezoidal structure. The disadvantage is that there is no steering sensor and micro-electronic controller, the steering accuracy is low, and it is not easy to control; and the space position of the vehicle itself is strict. The body is large, so it is not easy to use in narrow spaces. Contents of the invention [0004] The object of the present invention is to provide a decentralized power steering system for a multi-axle load-carrying vehicle that can steer in a narrow space and is easy to operate and steer flexibly. [0005] In order to achieve the abo...
