Description
Technical field
The present invention relates to a kind of automobile power assembly hydraulic suspension, relate in particular to a kind of power assembly hydraulic suspension that has the mechanical type feedback control structure.
Background technique
Because people suspend to General Purpose Rubber and the General Purpose Rubber hydraulic mount has comparatively ripe manufacturing processing technic, their price is cheaper again simultaneously, therefore obtained using widely, but General Purpose Rubber suspends and the rubber hydraulic mount is limit by rubber property and self structure, can't fundamentally eliminate the low-frequency resonance and the high-frequency noise of power assembly; They still can not satisfy the consumption demand to the more and more higher clients of riding comfort requirement in the vibration of high frequency attenuation power assembly, and the Design trend of body lightening increasingly sharpen above-mentioned phenomenon, cause the client to complain and increase; Though and half initiatively magnetic rheological body hydraulic suspension and ACTIVE CONTROL formula hydraulic mount possess good vibration isolation, damping performance, complex structure mostly, cost is too high, still in the experiment test stage, popularization and application needs time.
Summary of the invention
The objective of the invention is to by on the General Purpose Rubber hydraulic mount, increasing a kind of feedback control structure, improve its performance aspect decay power assembly low frequency large amplitude and high frequency small amplitude motion, improve greatly and be prone to resonance when motor operates in than the slow-speed of revolution, be prone to the phenomenon of noise when operating in higher rotation speed, the riding comfort of vehicle is further improved.
Another object of the present invention is to provide a kind of power assembly hydraulic suspension that has the mechanical type feedback control structure.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of power assembly hydraulic suspension that has the mechanical type feedback control structure that the present invention relates to, on common hydraulic mount basis, innovate, increased a kind of feedback control structure, can the time change as required on the spot suspend in the damping of working liquid body, damping that thereby making suspends when possessing the low frequency large amplitude is very big, the very little dynamic response of damping during the little amplitude of high frequency, realize this target neither need semi-actively controlled suspend essential magnetic rheological body and coil with high costs, do not need the control module of ACTIVE CONTROL formula hydraulic mount complexity and loaded down with trivial details calibration process yet, with low cost being easy to popularized, and the car load travelling comfort will improve greatly.Be specifically related to: on the basis of original damp channel, adopt variable damping system again.By ball pin connecting rod the vibration that suspends is converted into damping spool moving up and down in valve pocket, have two pairs of relative slits on spool and the valve pocket, liquid can be from the upper liquid chamber that the suspends seam on valve pocket earlier, and the seam on spool again is after spool bore flows to down liquid chamber; Valve pocket is fixed, when spool moves up and down in valve pocket, will changing of seam on the spool and the seam on the valve pocket over against area, thereby can change flowing through their damping that liquid produced, the relative movement of spool and valve pocket is big more, will be more little over against area, and the damping that liquid is produced is also just big more, thereby making suspends, and to have under the good condition of starting building a damping very big, the very little dynamic response of damping under the small vibration operating mode.
For realizing above-mentioned technical goal, the key structure of technological scheme of the present invention is by ball head connecting rod, the damping spool, the valve pocket of band double helix inertia channel is formed, and ball head connecting rod is a split-type, its small end and connecting bolt link, big end links with the damping spool, and the damping spool can slide in valve pocket, and spool has two guide rail shoulders, limiting its rotation in valve pocket, thereby guaranteeing that spool stitches with the microscler damping of valve pocket aligns all the time.When power assembly vibrated, ball head connecting rod drove the damping spool and slides up and down in valve pocket, just can regulate when spool slides that the two microscler damping stitches in valve pocket over against area, thereby can feedback regulation flow through the damping of working liquid body.Allow the axis of connecting bolt and the axis of damping spool that slight angle is arranged.
