Description
Technical field
The present invention relates to device, relate in particular to the initiatively adjustable hydraulic damper of vehicle suspension damping with spring and damper combination.
Background technology
The notion of semi-active suspension is put forward the seventies by people such as Crosby, and its large-scale production and application start from the beginning of the eighties, introduced the first generation at that time and become damping shock absorber, but it is very limited to the improvement of suspension property; The beginning of the nineties, F.H.Besinger, R.Rajamary, people such as Robin have also carried out research separately respectively to semi-active suspension, and have done a large amount of experiments; In recent years, semi-active suspension and active damping adjustable shock absorber thereof have been developed out corresponding product.
Generally speaking, semi-active suspension is not still accepted by industry member far away.One of reason is to lack real reliable and cheap recoverable reserves, also has many problems to remain to inquire into and solve on the other hand in theory.The present Research of whole semi-active suspension system to a large extent, is also continuing initial thinking always, mainly is to design with control algorithm at corresponding automatically controlled active damping adjustable shock absorber to study.It all has higher requirement for the hardware and software of system.Such as at hardware aspect, its requires to have response fast, the integrated sensor of intelligentization of function admirable, the actuator that contamination resistance is strong and can be used for the performance-oriented microprocessor of control in real time; Aspect software, it also will have the new theory that can be used for real-time control of combination development of nonlinear theory utilized and Intelligent Control Theory.And these technology also can not be solved well in present stage.Many sensors, high-grade actuator and the application of performance-oriented treater also will certainly make the total system cost increase substantially, and the reliability of total system and performance all can not well be guaranteed.
Summary of the invention
The invention provides a kind of simple in structure, low, dependable performance, and become the initiatively adjustable hydraulic damper of vehicle suspension damping of factor affecting can adapt to various condition of road surfaces and suspension self on a large scale the time the performer requirement.
It comprises the hydraulic pressure adjustable damping control cock that two control cocks are formed, the cushion cylinder, the petrol storage tank that link to each other with hydraulic pressure adjustable damping control cock the present invention.Cushion cylinder epicoele link to each other with an end of an end of the check valve of first control cock, two series connected fixed throttle port dampers, an end of settable orifice damper through first oil circuit; The cavity of resorption of cushion cylinder links to each other with the other end of the other end of the check valve of first control cock, two series connected fixed throttle port dampers, the other end of settable orifice damper through second oil circuit, and the cavity of resorption of cushion cylinder links to each other with an end of an end of the check valve of second control cock, two series connected fixed throttle port dampers, an end of settable orifice damper through second oil circuit; The other end of the other end of the other end of the check valve of second control cock, two series connected fixed throttle port dampers, settable orifice damper connects petrol storage tank through the 3rd oil circuit.
The present invention has following characteristics:
1) simple in structure, it is a pure mechanical-hydraulic damping network structure, to performer require low, reliably good and be convenient on vehicle, realize;
2) functional, because the dynamic pressure feedback characteristics of this hydraulic damping network internal, make and the influence of the factor that becomes when it can adapt to various condition of road surfaces and suspension self on a large scale can realize that damping is initiatively adjustable, it has most of function of automatically controlled semi-active suspension;
3) low price, because being direct information by cushion cylinder internal hydraulic pressure power, it reflects road surface and vibration of vehicle situation thereof, so it does not need various additional sensors to realize the signal conversion, the total system cost is reduced significantly, and the reliability of total system and performance can well be guaranteed.
Applied range of the present invention, it both can be used for car, racing car, high-grade este wagon; Also can be used as various vehicles, the vibration damping of device, insulator.
