Problems solved by technology

[0005] 1. Delays are prone to occur in steering control, and the response speed to steering commands is slow
[0006] 2. Deviations are prone to occur in the steering control of the front and rear axles, and it is easy to cause a large inner wheel difference in the rotation of a multi-axle articulated vehicle
[0007] 3. When a single component fails, the error cannot be reported in time, resulting in the failure of the entire steering system to operate normally

Abstract

The invention provides a high-precision quick-response hydraulic steering system capable of being applied to an intelligent rail electric vehicle and the intelligent rail electric vehicle provided with the hydraulic steering system. The hydraulic steering system has characteristics of quick response, high precision and high reliability, the intelligent rail electric vehicle can achieve accurate control over left-right rotation of an axle and high-precision closed-loop control over vehicle steering, and the safe driving requirement of trackless traffic can be met.

Description

technical field [0001] The invention relates to the field of trackless traffic, in particular to a steering system for a multi-axle trackless vehicle. Background technique [0002] Traditional rail transit vehicles need to run along special tracks during driving, while smart rail trams do not need physical tracks during driving, but directly drive on regular roads and run along preset virtual tracks. [0003] In order to improve the transport capacity, most trackless vehicles adopt multi-axle design. In order to meet the requirements of maneuverability and curve passing ability of multi-axle vehicles when transferring short-distance sites or turning at low speeds, all the axles of the currently produced trackless vehicle chassis are Or mostly have steering capability. [0004] The chassis steering of multi-axle vehicles in the prior art mostly adopts pure mechanical tie rod steering or mechanical hydraulic control steering, but these steering systems still have the followin...
