Mining dump truck hydraulic brake control integrated system with large electric wheel

Abstract

The invention discloses a mining dump truck hydraulic brake control integrated system with large electric wheel. The mining dump truck hydraulic brake control integrated system with large electric wheel comprises a variable pump, an oil tank, a high-pressure oil filter, a front wheel brake, a rear wheel brake, a parking brake, a brake pedal valve, a front guide control valve, a rear guide control valve, a first energy accumulator, a second energy accumulator, a second shuttle valve, the mining dump truck hydraulic brake control integrated system with large electric wheel further comprises a brake control integrated valve group provided with a plurality of cartridge valves, the variable pump is connected with the brake control integrated valve group via the high-pressure oil filter. The mining dump truck hydraulic brake control integrated system with large electric wheel is high in work reliability, simple in manufacture, low in use cost, the standard general hydraulic components are integrated into the hydraulic brake control system, the elements are concentrated with high integration degree, small space usage, little pipeline and convenient maintenance; the operation is simple, the function is strong, the automation control degree is high, the action interlocking relationship is perfect, the safety performance is high for brake control for large mining dump truck equipment.

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...
