Description

Technical Field

[0001] The utility model relates to the technical field of automotive braking, and particularly relates to a valve block for an integrated intelligent braking system. Background Technique

[0002] With the popularization of automotive electrification and driverless driving, the convenient vacuum source of the automotive braking system is lost, so it is necessary to cancel the vacuum booster; in addition, the braking requirements of driverless driving put higher demands on the active braking performance and service life of the system, making the currently widely used electronic stability control system (ESC) unable to meet the requirements, prompting the generation and gradual popularization of a new generation of wire-controlled braking systems, and the most basic wire-controlled braking system of the electronic booster is more and more widely used. In the electronic booster system, the hydraulic booster has the best performance. When braking hydraulically, the driver steps on the brake pedal, and the pedal feel is completely formed by the pedal simulator. The integrated intelligent braking system IHB is a highly integrated braking system that abandons the traditional vacuum booster and instead uses an internal motor or hydraulic device of the system to directly provide braking force to achieve vehicle braking.

[0003] In the related art, the control of the integrated intelligent braking system is mainly realized by various control valves installed on the hydraulic valve block. As an important part of the system, the structure and performance of the valve block directly affect the performance of the entire braking system. However, the existing valve block has a complex structure, a large volume, inconvenient installation, and the connection between each channel is not optimized enough, resulting in limited response speed and control accuracy of the braking system.

Multiple installation parts are preset on the valve block body, which is convenient for the quick installation and positioning of each component, reduces the installation difficulty and cost. Through the configuration of normally open valves and normally closed valves and the design of connection channels, the fine control and intelligent management of the braking system are realized, and the braking performance and safety are improved.

Once the transmission mechanism is fixed in place, the anti-rotation holes will exert their fixing effect to ensure that the transmission mechanism will not rotate unexpectedly due to external factors during normal operation.
