The apparatus and method disclosed in this document pertain generally to correcting and dampening undesirable vehicular movement. More particularly, the new and useful stabilizer disclosed and claimed in this document pertains to an ride stabilizing system. The stabilizer is particularly, but not exclusively, useful for dampening the ride of vehicles like skid steer loader vehicles and four-wheel drive front loaders.
BACKGROUNDSome vehicles like skid steer loader vehicles, often called “bobcats” in the industry, and four-wheel drive front loaders, and similar vehicles bearing considerable loads, evidence undesirable movements during operation. Undesirable vehicular movements may be caused or induced on vehicles that use limited or no suspension, are out of balance, yet must traverse irregular surfaces, thus inducing kinetic energy reactions similar to an accordion effect, such as bouncing, rocking, and so on. The undesirable movements are disorienting and disconcerting to vehicle drivers, and cause loads carried by such vehicles to further accentuate the undesirable movements. Suggestions have been made for dampening such movements, but none provides the substantially leveled ride that the ride stabilizing system shown in this document allows. Accordingly, a need exists in the industry for a new, useful and improved ride stabilizing system.
SUMMARYThe ride stabilizing system includes a housing that is formed with two chambers. A piston is positionable in each chamber. A unique leakage control system is attached to each piston. The housing is shaped, and includes apparatus, for selectively injecting variable amounts of gas and fluid into the two chambers. In general, the leakage control system includes applicators that contact the inner surface of each chamber. Each applicator is designed to hold a lubricant. The applicators are mounted in ducts formed in the housing. O-rings also are included in the leakage control system.
It will become apparent to one skilled in the art that the claimed subject matter as a whole, including the structure of the apparatus, and the cooperation of the elements of the apparatus, combine to result in a number of unexpected advantages and utilities. The structure and co-operation of structure of the ride stabilizing system also will become apparent to those skilled in the art when read in conjunction with the following description, drawing figures, and appended claims. Accordingly, the foregoing has outlined only broadly the more important features of the invention to better understand the detailed description that follows, and to better understand the contributions to the art. The ride stabilizing system is not limited in application to the details of construction, or to the arrangements of the components, provided in the following description and drawing figures, but is capable of other embodiments, and of being practiced and carried out in various ways. The phraseology and terminology employed in this disclosure are for purpose of description, and therefore should not be regarded as limiting. As those skilled in the art will appreciate, the conception on which this disclosure is based readily may be used as a basis for designing other structures, methods, and systems. The claims, therefore, include equivalent constructions. Further, the abstract associated with this disclosure is intended neither to define the ride stabilizing system, which is measured by the claims, nor intended to limit the scope of the claims. The novel features of the ride stabilizing system are best understood from the accompanying drawing, considered in connection with the accompanying description of the drawing, in which similar reference characters refer to similar parts, and in which:
BRIEF DESCRIPTION OF THE DRAWING
As shown in
The leakage control assembly, in its broadest context, includes a plurality of applicators that are positioned to be in contact with the inner surface of the at least two chambers. The plurality of applicators is selected from the group of applicators consisting of applicators, blades, spreaders, wipers, squeegees, brushes, and sponge-type devices. The leakage control system also includes one or more lubricants infused in plurality of applicators. A plurality of peripheral ducts formed in the piston, and one or more o-rings engageable with the plurality of peripheral ducts.

In operation, therefore, leakage control assembly 28 of ride stabilizing system 10 solves lubriscosity problems not solved by other suggestions for dampening a vehicle ride using apparatus similar to ride stabilizing system 10, including what are known generally as accumulators. The lubricants used in association with leakage control assembly 28 of ride stabilizing system 10 eliminates the need for an opening through the cylindrical body 30 of pistons 26a,b or in any other structural feature of ride stabilizing system 10. In addition, leakage control assembly 28 of ride stabilizing system 10 includes a variety of leakage control redundancies—including at least annular closure device 42 mounted in groove 38, sealing ring assemblage 52 installed in slot 50, and lubric sleeve 58 set in indenture 56 interposed in cylindrical body 30 between groove 38 and slot 50—for forming a reliable seal and insuring immiscibility of gases and fluids during operation of ride stabilizing system 10. As will be evident to one skilled in the art, the design and structural cooperation of leakage control assembly 28 is responsive to leakage problems induced by gravity. The use of two opposing chambers 18a,b, in combination with leakage control assembly 28, is contrary to all prior teaching in the field.
