DETAILED DESCRIPTION

Embodiments of the present invention recognize that existing leaf spring suspensions carry large amounts of weight but are over constrained due to the excessive load. This over constraint leads to induced stress on the leaf spring suspensions when the suspension bracket articulates. Therefore, embodiments described herein provide a new axle-to-leaf spring mount that incorporates limited rotation in a direction parallel to the axis of the vehicle. As a result, adding a rotational degree of freedom would make it easier for the suspension to articulate and reduce the amount of induced stress. As an added improvement, embodiments described herein provide increased range-of-motion for the vehicle axle in off-road or uneven terrain conditions. Additionally, embodiments described herein result in lower stresses in the axle housing resulting in longer life. This is most effective for heavily loaded vehicles with a high-count leaf spring stack including, but not limited to, armored vehicles.

Embodiments described herein provide an articulating leaf spring suspension configured to provide a new degree of freedom in vehicle suspensions. For example, adding a rotational degree of freedom between the axle housing and leaf springs improves the stress experienced on a vehicle suspension system. Therefore, embodiments described herein reduce or eliminate the over constraint placed on the vehicle suspension components without degrading load carrying capabilities or on-road handling characteristics. As a result, due to the additional pivot axis, the axle housing is able to pivot independently of the spring stack, thus reducing and/or eliminating stresses induced in the springs or housing.

Embodiments of the invention will now be described with reference to the Figures.

FIG. 1 illustrates a perspective view of an example suspension system 100 in accordance with several embodiments of the present disclosure. The suspension system 100 includes an articulating bracket assembly 110 clamped around a rear axle housing 130 and disposed on a leaf spring suspension 120. The articulating bracket assembly 110 enables the leaf spring suspension 120 and/or axle 130 to pivot relative to one another in the direction of the long axis of the axle 130 (labelled X in FIG. 1), thus reducing stresses experienced by axle housing 130 during travel. The articulating bracket assembly 110 may include rubber bushing components configured to add additional degrees of movement within the confines of the vehicle suspension system so that less impact is experienced by axle housing 130. In addition, pivot points of the articulating bracket assembly 110 are disposed in the plane of the long axis (X) of the axle 130, thus enabling pivoting of the leaf spring 120 and/or axle 130 relative to one another without increasing the overall distance between the leaf spring 120 and the axle 130 (and thus, articulating bracket assembly 110 of the present disclosure does not increase the overall height of a vehicle having the suspension system 100 installed).

FIG. 2 illustrates a perspective view of the articulating bracket assembly 120 in accordance with several embodiments of the present disclosure. As used in the description below, “exterior” refers to the face of the bracket 112 that directed away from the axle 130, and “interior” refers to the face of the bracket 112 that directed toward the axle 130. The articulating bracket assembly 112 includes a base plate 202, a first bushing pillar 204 disposed on a first end of the base plate 202, and a second busing pillar 206 disposed on a second end of the base plate 202. A gap or opening 208 is defined between the first and second pillars 204/206, where the gap 208 is dimensioned to receive an end 132 of an axle 130. The first pillar 204 defines an opening in which a first bushing assembly 210 is disposed. The first bushing assembly 210 extends through the thickness of the first pillar 204 from an exterior face of the pillar 204 (the face illustrated in FIG. 2) to an interior face of the pillar 204. The first bushing assembly 210 includes a first hollow sleeve 214 surrounded by first bushing 212. The sleeve is dimensioned to receive a bolt 216 therethrough. The first bushing 214 may be formed of a flexible material such as, for example, rubber, plastic, etc. The position of the first bushing assembly 210 within the first pillar 204 is selected so that the center of the sleeve 214 is approximately of a plane defined through the center of the long axis of the axle 130, i.e., the center of the sleeve 214 is approximately coplanar with the long axis (X) of the axle 130.

Similar to the first pillar 204, the second pillar 206 defines an opening in which a second bushing assembly 220 is disposed. The second bushing assembly 220 extends through the thickness of the second pillar 206 from an exterior face of the pillar 206 (the face illustrated in FIG. 2) to an interior face of the pillar 206. The second bushing assembly 220 includes a second hollow sleeve 222 surrounded by second bushing 220. The sleeve 220 is dimensioned to receive a bolt 224 therethrough. The second bushing 220 may be formed of a flexible material such as, for example, rubber, plastic, etc. The position of the second bushing assembly 218 within the second pillar 206 is selected so that the center of the sleeve 222 is approximately of a plane defined through the center of the long axis of the axle 130, i.e., the center of the sleeve 222 is approximately coplanar with the long axis (X) of the axle 130.

The articulating bracket assembly 120 may also include a cap component 226 secured to a top portion of the first and second pillars 204/206 and extending along a length of base component 202. The cap component 226 comprising an arched middle portion 228, the arch 228 spanning the gap 208 between the first and second pillars 204/206. The cap component 226 may be bolted to, or otherwise secured to, the top of the first and second pillars 204/206, as illustrated using a plurality of bolts such as bolts 230 and 232.

The articulating bracket assembly 112 may also include one or more top axle constraints to ensure a secure fit of the bracket assembly 112 around the end of the axle 130. For example, the articulating bracket assembly 120 may include an exterior constraint component 252 secured to an uppermost exterior surface of the first and second bushing pillars 204/206 and having an arched middle section 254 that fits within the arched middle portion 228 of the cap component 226. The arched middle section 254 is dimensioned to contact the end 132 of axle housing 130, thus securing the end 132 of the axle 130 against the arched middle section 254, the pillars 204/206 and the base plate 202. In some embodiments, the articulating bracket assembly 112 may also include an interior constraint component 254 secured to an uppermost exterior surface of the first and second bushing pillars 204/206, and having a shape and function substantially similar to the exterior constraint 252, described above. In some embodiments, the exterior and/or interior constraints 252/256 may be welded to the first and second bushing pillars 204/206. In other embodiments, the exterior and interior constraints 252/256 may be bolted (not shown) to the first and second bushing pillars 204/206. The top constraints 252 and/or 256 generally provide additional strength and material thickness around the top region of the axle 130. As illustrated, the cap component 226 has a width to cover the top surfaces of the first and second bushing pillars 204/206 and the exterior and interior constraints 252/256, such that top surfaces of the exterior and interior constraints 252/256 are coplanar with the top surfaces of the first and second bushing pillars 204/206, and thus the cap 226 “covers” the top surfaces of the exterior and interior constraints 252/256. In other embodiments, the exterior and interior constraints 252/256 and the cap 226 may be formed as a unitary structure.

The articulating rear suspension apparatus 200 may also include a bracket component 260 (e.g., exterior bracket component 262 and interior bracket component 264) secured to bushing assembly 112 using bolts (e.g., plate bolt 272) extended through upper distally opposed openings aligned with first rubber bushing 220 and second rubber bushing 222. For example, bracket component 260 may include exterior bracket component 262 secured to first bushing component 210 via a first bushing bolt (e.g., first bolt 214) and secured to second bushing component 212 via a second bushing bolt (e.g., second bolt 216).
