Steering brake system and steering brake control method

Abstract

The invention belongs to the technical field of engineering machinery, and discloses a steering brake system and a steering brake control method. The steering brake system comprises a steering pump, aleft steering valve, a right steering valve, a left brake valve, a right brake valve, a left steering clutch, a right steering clutch, a left brake clutch and a right brake clutch. The steering pumpis directly communicated with the left steering clutch through the left steering valve and used for controlling the rotating speed of the left wheel; the steering pump is directly communicated with the right steering clutch through the right steering valve and used for controlling the rotating speed of the right wheel; the steering pump is directly communicated with the left brake clutch through the left brake valve and is used for controlling the brake of the left wheel; the steering pump is directly communicated with the right brake clutch through the right brake valve and used for controlling braking of the right wheel. According to the steering and braking system, steering and braking can be achieved without other parts and structures between the valves and the clutches corresponding to the valves, the structure is simplified, the production and development period is shortened, and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a steering braking system and a steering braking control method. Background technique [0002] With the development of technology, the intelligence level of construction machinery is also improving, and electronic control is the foundation. Only when the walking system is electronically controlled can it be more convenient to integrate advanced functions such as automatic downshifting, thereby enhancing product competitiveness. [0003] At present, users have higher and higher requirements for control comfort. For example, although the electronically controlled walking system can meet customer control comfort requirements, the structure is complex and the development cycle is long, resulting in high production costs, high oil cleanliness, and high control requirements. , the stability of the system quality is not ideal, and there is a problem of low reliability. Th...

Problems solved by technology

[0003] At present, users have higher and higher requirements for control comfort. For example, although the electronically controlled walking system can meet customer control comfort requirements, the structure is complex and the development cycle is long, resulting in high production costs, high oil cleanliness, and high control requirements. , the system quality stability is not ideal, and there is a problem of low reliability

Therefore, domestic products are completely at a disadvantage in the process of competing with international brands, especially the development of control logic and control programs, which is still in the initial stage of exploration in China
