Description
Technical field
The present invention relates to adjustable for height automotive suspension technology, particularly be suitable for the automotive suspension elevation control mechanism therefor that automobile air spring suspension, hydro-pneumatic spring suspension or hydraulic spring suspension realize that the height multistation is adjusted.
Background technology
At present, in the automotive suspension designing technique of air spring suspension, hydro-pneumatic spring suspension or hydraulic spring suspension, the suspension height that keeps automobile when guaranteeing the load change when automobile, equal control mechanisms of the height-control valve of employing shown in accompanying drawing 1 (with air as the transferring power medium) or accompanying drawing 2 (with oil as the transferring power medium) usually.Its structure working principle is: be example with Fig. 1, the valve body of height-control valve 1 is fixed on the vehicle body, the Control arm 2 of height-control valve is hinged on the axletree by connecting rod 4, and the A mouth connects high-pressure air source or oil sources, and the B mouth connects air bellow or the hydro-pneumatic spring or the hydraulic spring of automotive suspension.At balance position, when vehicle body was in nominal altitude, the V2 plate valve was sealed valve port on the valve body 1 and the valve port on the valve rod P simultaneously, and air bellow is neither inflated, and does not also exit; When load increases, when bodywork height descends, Control arm 2 is with respect to upwards swing (the H0 point moves to the H1 place) of valve body, the V2 plate valve is lifted high-pressure air source is communicated with air bellow, the air bellow inflation, vehicle body raises, and the admission port of height-control valve was closed when Control arm 2 was got back to the H0 position, and spring is no longer inflated; When load reduces, when bodywork height increased, H0 point was pulled to H2 place, and height-control valve makes air bellow communicate with logical atmosphere, and air bellow is exitted, bodywork height decline, and when the H2 point falls back to the H0 point, air bellow no longer exit (B and the cut-out of C path).
The height control system of hydro pneumatic suspension is similar to air suspension, and its difference is that control agent is not that air but high pressure oil system schematic are referring to Fig. 2.
Above-mentioned height-control valve all is to keep auto body to be on a kind of calibrated altitude, so be called single station control, only can bodywork height be controlled on certain level according to automobile load.
Summary of the invention
The purpose of this invention is to provide a kind of multiple work position height control mechanism for automobile suspension, to realize any adjustment to the automotive suspension height.
Multiple work position height control mechanism for automobile suspension of the present invention, by being connected the suspension air bellow, height-control valve between hydro-pneumatic spring or hydraulic spring and air pressure or hydraulic efficiency power unit on the pipeline constitutes, the valve body of height-control valve is installed on the vehicle body, the Control arm of height-control valve by rod hinge connection on axletree, it is characterized in that the lever that also is hinged between described Control arm and the connecting rod, be that end is hinged with Control arm among the lever, one of lever end and connecting rod are hinged, it is hinged that the other end of lever and middle-end are articulated in an end of three end communtation arms on the vehicle body, and the other end of three end communtation arms is hinged by drawing piece and control dial and the control dial that is arranged in the operator's compartment.
Adopt multiple work position height control mechanism for automobile suspension of the present invention, both can carry out automatic guidance, can in operator's compartment, adjust bodywork height arbitrarily by chaufeur as required again by control dial to the height of suspension system, with make things convenient for the passenger or borrow thing about.
