Implementation method of vehicular independent steering system

Abstract

The invention provides an implementation method of a vehicular independent steering system. The system includes a plurality of wheel sets, a steering device, an angle sensor, a travel driving device and a computer, wherein the wheel sets are arranged on the lower portion of a vehicle, and independent steering of the wheel sets can be achieved; the steering device drives steering of the wheel sets;the angle sensor is used for detecting the actual steering angles of the wheel sets; the travel driving device is used for driving the wheel sets to travel; the computer is used for cooperatively controlling the steering angles of the wheel sets and travel driving. The limit angles of clockwise steering and clockwise steering of the wheel sets driven by the steering device are unsymmetrical relative to the neutral position. The steering device achieves the asymmetry, relative to the neutral position, of the steering capability of the wheel sets and independent steering of the wheel sets, andthe computer achieves coordinated control over the steering angles and the travel directions of the wheel sets, so that a vehicle has a wider range of the steering angles, and the steering flexibilityof the vehicle is greatly improved on the basis that the cost of hardware is scarcely increased.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a method for realizing an independent steering system of a vehicle. Background technique [0002] In recent years, with the increasing demand for domestic large-scale transportation and large-tonnage workpieces, a large number of independently steering hydraulic transport vehicles have emerged, such as fully hydraulic power flatbed transport vehicles and fully hydraulic modular vehicles that can be flexibly combined. These vehicles are currently operating in all walks of life and play an important role in our modern manufacturing and transportation industries. [0003] Since large-tonnage vehicles need to have a large load capacity, these vehicles generally have many wheel sets to carry the load. It is an economical solution to use link steering for multiple wheel sets, but with the increase of wheel sets, using link steering The difficulty of driving is also increasing, and...

AI Technical Summary

Problems solved by technology

However, in specific work situations, the vehicle needs to have greater steering capability, and the steering angle of the wheel set is limited by the steering device. If the steering angle range of the steering device is increased, the design and manufacturing cost of the steering device will increase accordingly, and the steering device The volume of the vehicle will become larger, which will bring difficulties to the design of the already compact vehicle
