Description

technical field

[0001] The invention relates to an integrated hydraulic braking control system, in particular to an integrated hydraulic braking control system for a large electric wheel mining dump truck. Background technique

[0002] The electric wheel mine dump truck hydraulic brake control system is one of the core technologies of the electric wheel transport vehicle. Most of the hydraulic brake control systems of similar products at home and abroad adopt the traditional control system composed of multiple discrete components, which has defects such as many components, complex pipelines, low work reliability, troublesome maintenance, and high manufacturing costs; The control function is relatively simple, for example, the hydraulic brake control system of dump trucks produced by Komatsu Dresser Company and Belarus Company in the early stage is like this.

[0003] In order to meet the needs of domestic large-tonnage electric wheel mine transport vehicles, it is urgent to...

Examples
