The specific embodiment
As shown in Figure 1 and Figure 2, a kind of shock damper for boat of the present invention, this Shock absorber comprises outer sleeve 1 and is used for the top board 2 and the base plate 3 of closed outer casing tube 1 top and bottom, the medium position of described outer sleeve 1 internal cavities is provided with ball float 4, this ball float 4 is separated into two chambers 11/12 up and down with the internal cavities of outer sleeve 1,2 on the upper surface of described ball float 4 and top board are provided with elastic component 5, and 3 of the bottom surface of described ball float 4 and base plates also are provided with down elastic component 6.In addition, in order to reduce effectively than the impact of high sea to ship, be provided with hydraulic oil 7 in the lower chamber 12 of described outer sleeve 1, the liquid level line of described hydraulic oil 7 probably is positioned at half height and position of lower chamber 12, and described ball float 4 selects for use the center to be provided with the metal solid of centre hole 41 usually, and its profile is cylindrical.
In the present invention, elastic component 6 was all selected compression performance compression spring preferably for use under described upward elastic component 5 reached; Usually, be provided with a compression spring between ball float 4 upper surfaces and top board 2 bottoms, 3 of described ball float 4 bottom surfaces and base plates are provided with the Internal and external cycle compression spring 61,62 that two diameters do not wait.In addition, for this Internal and external cycle compression spring 61,62 being positioned over closely 3 of ball float 4 bottom surfaces and base plates, described base plate 3 is provided with a end with compression spring and is fixed on adapter plate 8 on the base plate 3.As shown in Figures 3 and 4, described ball float 4 bottom margin positions are provided with the recess 42 that is used to hold outer ring compression spring 61 tops, and the midway location of described ball float 4 bottoms also is provided with the groove 43 that is used to hold inner ring compression spring 62.
Same as described above is that the top of described ball float 4 also is provided with the concave station 44 that is used for sheathed compression spring bottom, so just compression spring stably can be arranged between the surface of top board 2 bottoms and ball float 4.
In addition, in order to make ball float 4 that two 11,12 of chambers up and down that outer sleeve 1 is divided into are had the better seal performance, the outside face of described ball float 4 is provided with sealant ring recess 45, and sealing aprons slot 45 is provided with and is used for leak free O-ring seal 9.
Shock damper for boat of the present invention is to be installed in the hull, usually for general small-sized speedboat, as Fig. 5 and shown in Figure 6, corresponding to fore and position, stern-side hull axis, be provided with three Shock absorbers 10 altogether, and for the stability of balance hull better, the overall weight that places the Shock absorber 10 of fore position roughly is the twice that places each Shock absorber weight of Stern Post.When ship during in fast running, if run into bigger stormy waves again, the fore position will be lifted rising, stern can descend, like this, whole hull is extremely unstable, but after Shock absorber 10 has been installed, when meeting than high sea, the bottom compression spring of the outer sleeve 1 of Shock absorber can compress under the effect of impact, the compression spring elongation on top, the compression spring of these top and the bottom can make the compression spring on top compress under the effect of restoring force, two circle compression spring elongations of bottom, because the restoring force of bottom compression spring is greater than the restoring force of top compression spring, ball float sinks, and can make that upwards the fore of lifting is pulled downwards; In like manner, under the effect of the Shock absorber that the stern of sinking also can be established in this place stern is lifted, can guarantee that whole hull has stability preferably.In addition, owing to be provided with hydraulic oil in the chamber of bottom, when impacting than high sea, the hydraulic oil of lower chamber is by flowing into upper chamber behind the centre hole, this hydraulic oil not only plays lubricating effect preferably, and because hydraulic oil to the buoyancy of ball float itself, makes ball float also can keep balance and stability performance preferably when sinking, thereby make whole hull to travel by pulsation-free, stability is good; In addition, this hydraulic oil can also play the damage of the bigger impulsive force in the buffering external world to compression spring, to guarantee compression spring is arranged long service life.
The present invention is not limited to above-mentioned embodiment, for example: the quantity as the compression spring of last elastic component not only is one, can be two or more, identical therewith, the compression spring number of following elastic component also can be for greater than two, but usually for shock-absorbing performance is preferably arranged, should be as the quantity of the following compression spring of elastic component greater than the quantity of the compression spring of last elastic component, like that, every various changes of the present invention or modification are not broken away from the spirit and scope of the present invention, if these are changed and modification belongs within claim of the present invention and the equivalent technologies scope, then the present invention also means and comprises these changes and modification.
