The present disclosure generally relates to the field of vehicle suspension systems, and more particularly, to a system of resilient members configured to compress and expand as a linkage rotates about a linkage pivot.
The numerous advantages of the disclosure may be better understood by those skilled in the art by reference to the accompanying figures in which:
The present disclosure has been particularly shown and described with respect to certain embodiments and specific features thereof. The embodiments set forth herein are taken to be illustrative rather than limiting. It should be readily apparent to those of ordinary skill in the art that various changes and modifications in form and detail may be made without departing from the spirit and scope of the disclosure.
Reference will now be made in detail to the subject matter disclosed, which is illustrated in the accompanying drawings. Referring generally to

The walking beam suspension assembly 101 may include a shock absorbing assembly 113. The shock absorbing assembly 113 may include a linkage 114. The linkage 114 may include one or more linkage plates 114A and/or 114B which are rotatably coupled to the beam portion 102 via an linkage pivot bushing 115 retained by a locking nut 116. The linkage 114 may each include an arcuate slot 117 which may allow for limited travel of the linkage 114 relative to the beam portion 102 as the linkage 114 rotates about the linkage pivot bushing 115.
The shock absorbing assembly 113 may further include one or more elastically deformable members 118. In one example, as shown in
Referring to
Such a configuration may serve to reduce the force applied to the elastically deformable members 118 of the shock absorbing assembly 113 as compared to conventional, under-frame configurations of similar structures. In one example, the employment of the pivoting linkages 114 may reduce the forces applied to the elastically deformable members 118 by half relative to conventional, under-frame configurations of air bags. This may be accomplished via the additional pivot points provided by the linkage pivot bushing 115 may, when combined with the rotation 109 of the beam portion 102 around the mounting bushing 107, serving as additional force equalizers to further smooth load handling by the walking beam suspension assembly 101. The ability of each of the axle members 201 of a vehicle to articulate independently of the beam portion 102 via their associated shock absorbing assembly 113 further dampens any vibrations. It will be recognized above-referenced departure angle values are merely exemplary and additional ranges are contemplated depending on the potential degree of force 119 applied to the axle supports 104, the required travel distance of the linkage 114, and the elastic capabilities of the elastically deformable members 118.

One skilled in the art will recognize that the herein described components, devices, objects, operations, and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are contemplated. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar is intended to be representative of its class, and the non-inclusion of specific components (e.g., operations), devices, and objects should not be taken as limiting.
The previous description is presented to enable one of ordinary skill in the art to make and use the invention as provided in the context of a particular application and its requirements. As used herein, directional terms such as “top,” “bottom,” “over,” “under,” “upper,” “upward,” “lower,” “down,” and “downward” are intended to provide relative positions for purposes of description, and are not intended to designate an absolute frame of reference. Various modifications to the described embodiments will be apparent to those with skill in the art, and the general principles defined herein may be applied to other embodiments. Therefore, the present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.
It is further contemplated that each of the embodiments of the method described above may include any other step(s) of any other method(s) described herein. In addition, each of the embodiments of the method described above may be performed by any of the systems described herein.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” and the like). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, and the like” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, and the like). In those instances where a convention analogous to “at least one of A, B, or C, and the like” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, and the like). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
It is believed that the present disclosure and many of its attendant advantages will be understood by the foregoing description, and it will be apparent that various changes may be made in the form, construction, and arrangement of the components without departing from the disclosed subject matter or without sacrificing all of its material advantages. The form described is merely explanatory, and it is the intention of the following claims to encompass and include such changes. Furthermore, it is to be understood that the invention is defined by the appended claims.
