Description
Technical field
The invention belongs to antivibration area, relate to a kind of vehicle-mounted power station secondary vibration-proof structure.
Background technology
Vehicle-mounted power station is arranged in special vehicle internal independence cabin.The power station can produce stronger vibration when working.Use owing to being arranged on special vehicle, the vibration of jolting of special vehicle driving process can act on the power station.The vibration stack that the vibration in power station self and vehicle bring is easily resonated, and can cause the power station body to damage when serious.Existing mode is the shock absorber of one group of identical characteristics to be installed to weaken the vibration in power station in the bottom, power station.Existing special vehicle vehicle-mounted power station vibration damping form as shown in Figure 1.
The defective that existing method exists:
1, the vibration that produces for power station self that the shock absorber of single damping behavior can only be single cushions.
2, middlely can produce vibration because special vehicle travels, the vibration damping mode that vehicle-mounted power station is single at present is little to the Vibrant buffer effect that vehicle brings.Therefore can only realize at present the work of power station under the special vehicle quiescence, can't realize that the power station is in the work use of the dynamic driving process of special vehicle.
Summary of the invention
The technical matters that the present invention solves is to provide a kind of vehicle-mounted power station secondary vibration-proof structure, improves the cushioning performance of vehicle-mounted power station, realize vehicle-mounted power station at special vehicle the work use function under the static and two states that dynamically travels.
Technical scheme of the present invention is that a kind of vehicle-mounted power station secondary vibration-proof structure comprises damping frame, first order shock absorber, second stage shock absorber; First order shock absorber comprises three one-level damper units, and second stage shock absorber comprises two secondary damper units; Three one-level damper units lay respectively on damping frame; Two secondary damper units are arranged on respectively damping frame two ends; The secondary damper unit is comprised of upper damping block, lower damping block, vibration damping installation sleeve three parts; Upper damping block, lower damping block structure are identical, formed by metal shock reducing lining and rubber damping pad, and rubber damping pad outside coated metal vibration damping bush, rubber damping pad is cylindrical tube shape, is with up and down convex; The vibration damping installation sleeve is the tubular metal structure; Upper damping block, lower damping block then are embedded in the vibration damping installation sleeve rubber damping pad centre hole of upper and lower damping block respectively in the mounting hole of upper and lower embedding damping frame.
Key point of the present invention:
1, the unitized design mode of two kinds of different damping behavior shock absorbers.
2, the shock absorber group is at integrated fixing, the mounting means of damping frame.
3, the split type Vibration Absorption Designing of secondary shock absorber and nested mounting means.
The invention has the advantages that: vehicle-mounted power station secondary vibration-proof structure design can absorb the vibration of power station body and vehicle to the vibration that the power station produces, and the resonance of avoiding two kinds of vibration stacks to produce reduce the vibrating noise in power station.The shock absorber group is arranged on the integrated design of damping frame, is convenient to the installation in power station, and the whole tempering that is conducive to shock absorber group pedestal is fixed.The shock absorber flush type mounting structure of the second stage reduces the spatial volume that vehicle-mounted power station takies, and the vibration-proof structure of laminated rubber between vibration damping installation sleeve and vibration damping bush is conducive to cushion the vibration of horizontal direction in Vehicle Driving Cycle.Realize the work use function of vehicle-mounted power station under and dynamically travel two states static at special vehicle by the present invention.

The specific embodiment
As shown in Figure 3, a kind of vehicle-mounted power station secondary vibration-proof structure of the present invention comprises damping frame 6, first order shock absorber, second stage shock absorber; First order shock absorber comprises three one-level damper units 7, and second stage shock absorber comprises two secondary damper units 8; Three one-level damper units 7 are positioned on damping frame (6), lay respectively under hard-wired 3 positions, power station; Two secondary damper units 8 are arranged on respectively damping frame two ends.
The one-level damper unit adopts common (existing) shock absorber that is applied to generator set; As Fig. 4, shown in Figure 5, the secondary damper unit is comprised of upper damping block, lower damping block, vibration damping installation sleeve 10 3 parts.Upper damping block, lower damping block adopt identical structure, upper damping block, lower damping block all are comprised of separately metal shock reducing lining 12 and rubber damping pad 11 respectively, rubber damping pad 11 outside coated metal vibration damping bush 12 (clad outside rubber damping pad), metal shock reducing lining 12 is metal cylinder tubular structure, rubber damping pad is cylindrical tube shape, is with up and down convex.The rubber damping pad of damping block, lower damping block on interlayer respectively between the metal shock reducing lining of vibration damping installation sleeve and upper damping block, lower damping block, vibration damping installation sleeve are tubular metal structure (height is identical with height after upper damping block, lower damping block are arranged on damping frame).
second stage shock absorber uses when assembling first with upper damping block, lower damping block is respectively from upper, lower both direction vertically embeds interior insertion of mounting hole of damping frame, again the vibration damping installation sleeve is embedded in, the rubber damping pad centre hole of lower damping block is fixed the two-layer rubber damping pad in up and down, pass the vibration damping installation sleeve by power station hold-down bolt 5 at last, damping frame integral body is fixed on car body corresponding position, first order vibration damping is put according to power station body installation fixing position and is fixed on damping frame, second stage shock absorber is determined its installation site according to the power station in the fixed position of special vehicle.The structure of second stage shock absorber and assembling mode are seen Fig. 4,5 signals.
