Hydraulic integrated control unit for hydraulic interconnection suspension and control method thereof

Abstract

The invention belongs to the technical field of vehicle suspensions, and particularly relates to a hydraulic integrated control unit for hydraulic pressure of a hydraulic interconnection suspension and a control method of the hydraulic integrated control unit. The control unit comprises a shell, a controller interface, a base body and an auxiliary assembly. The shell is fixedly connected with thebase body to form a sealed chamber. An electromagnetic valve is placed in the base body. The auxiliary assembly is mounted on the base body. The controller interface is fixed to the shell and is connected with the controller. An electromagnetic coil assembly is fixed to the base body through a connecting member to position a valve disc of a valve core assembly. A valve rod in the valve core assembly is in threaded connection with a moving iron core in the electromagnetic coil assembly. By means of the hydraulic integrated control unit for the hydraulic interconnection suspension and the control method, through the integration management of the electromagnetic valve, a hydraulic cylinder port, an oil injection valve, an accumulator port, an electrical control hardware structure and the like, a hydraulic interconnection suspension system is enabled to be modular, miniaturized and lightweight, the maintainability and safety of the system are greatly improved, and damage caused by other components of a vehicle or the intrusion of external objects is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension, and in particular relates to a hydraulic integrated control unit and a control method for hydraulic interconnected suspension hydraulic pressure. Background technique [0002] The suspension system is one of the important assemblies of the automobile chassis, which plays the role of transmitting force and moment between the body and the wheels. Interconnected suspension is a new type of suspension connection, which can timely connect the front and rear or left and right shock absorbing hydraulic chambers, so as to reduce the range of body posture changes and improve comfort or handling stability. In the current development of the discipline of hydraulic interconnected suspension, according to the actual driving conditions of the vehicle, dynamic switching between pitch mode, roll mode and vertical motion should often be realized to meet the driving needs of different working conditions...
