  • Patent number: 9285004
    Abstract: A silencer for a leaf spring assembly. The silencer is disposed between end portions of leaf springs. The silencer has a two-layer structure which has a fixing layer and a sliding layer which are integrally formed. The fixing layer has a projection portion, and the projection portion has an engagement portion at a leading end portion thereof. The fixing layer, which is fixed at the fixing side leaf spring, has a tensile strength higher than the sliding layer. The sliding layer, which abuts the sliding side leaf spring, has a hardness lower than the fixing layer. The projection portion of the fixing layer can have sufficient strength to resist the shearing force. In the sliding layer, undesirable noise generation is difficult, and even when a load transmission portion of an end portion of the sliding side leaf spring partially abuts the sliding layer, undesirable noise generation can be prevented.

  • Patent number: 7210673
    Abstract: A spring assembly includes a spring seat clamped to a leaf spring at a center portion. The spring seat includes a cutout for distributing clamping stresses in a substantially uniform manner across the leaf spring. The cutout provides a relief for a central portion of the leaf spring to uniformly distribute clamping pressures across the leaf spring. Uniformly distributing stresses across the width of the spring increases leaf spring fatigue life.

  • Patent number: 7195272
    Abstract: A vehicle suspension has axle end portions each pivotally coupled to an associated leaf spring and thereby to an associated supporting vehicle frame rail. Control rods are pivotally coupled to the axle at locations below the leaf spring pivots. Desirably, one of such control rods is pivoted to the axle at a location above the wheel axis and the other of such control rods is pivotally coupled to the axle at a location below the wheel axis. A steering mechanism for steering the steerable wheels of a tandem axle includes first and second steering gears mounted to a common frame rail and driven by a single mechanical coupling such as a T-miter box. These steering gears may control respective steering gears at the opposite side of the vehicle.

  • Patent number: 7066479
    Abstract: A vehicle axle assembly is provided including an axle housing having legs extending along an axis. Each housing leg has a wall defining an interior cavity with the wall having a first locating feature formed therein. The first locating feature may be an indentation in the wall of the axle housing that may be in the shape of a concave dimple or a trough running transverse to the axis. The first locating feature may also be a protrusion instead of an indentation. A suspension component is secured to the housing leg by clamps. A suspension component includes a second locating feature of a complimentary shape to the first locating feature. The locating features cooperate to axially locate the suspension component on the housing leg preventing lateral movement.

  • Patent number: 6991223
    Abstract: A suspension system includes a composite leaf spring having an arcuate segment that is located between a retaining pin and a bumper. The retaining pin includes a shank surrounded by a resilient tube. The bumper is located adjacent a rear wall of the bracket opposite the retaining pin. The bumper includes an arcuate face to engage the outer arc of the arcuate segment while the pin is at least partially surrounded by the arcuate segment. The end of the composite leaf spring is thereby securely yet resiliently retained within the front leaf spring attachment system without penetrating fasteners.

  • Patent number: 6966568
    Abstract: A suspension system includes a primary structural support such as an axle beam. To dampen movement of the beam, a leaf spring is attached to longitudinal mainframes which extend parallel to a vehicle centerline. A bracket assembly attaches the beam to the leaf springs by sandwiching the leaf spring therebetween. The bracket assembly also provides a support and mount for an air bag and a shock.

  • Patent number: 6910681
    Abstract: A tubular axle housing is provided with pairs of tabs that protrude or extend from the axle to a height or length sufficient to prevent the intermediate section of a U-bolt from sliding over the tab. The tabs also help locate and guide the U-bolt between the tabs during the assembly of a leaf spring to the axle housing. The tabs provide a positive locking feature for the U-bolts during service of a vehicle, to prevent the U-bolts from moving laterally along the axis of the axle tube. As a result, the joint between the leaf spring and axle housing is more secure.

  • Patent number: 6619637
    Abstract: A suspension spring arrangement for a vehicle having an upper elongated spring leaf (12) and a lower elongated spring leaf (14) with an upper elongated spring leaf (12) is provided with a slot (22) and a lower elongated spring leaf (14) is provided with a protuberance (24). When the upper and lower spring leafs (12, 14) are joined to one another, the protuberance (24) is accommodated within the slot (22) so as to prevent lateral displacement of the upper and lower spring leafs (12, 14) with respect to each other. Pounding and squeaking noises are prevented by the installation of a polymeric insert between the slot and the protuberance. The slot (22) and the protuberance (24) are configured in accordance with square, rectangular, and/or circular shapes, depending upon the particular application. A protuberance (24) and a slot (22) can be provided at each end of the suspension spring arrangement.

  • Patent number: 6595483
    Abstract: A vibration isolator including a bearing support and an elastic member that communicates with a vibration source. The elastic member is capable of bending from an original position to assume a more or less bowed position in response to changes in a load applied to the midportion of the elastic member intermediate its ends and returning essentially to its original position when the original load is restored. The elastic member engages a friction-resistant bearing surface on the bearing support at a distance spaced from each of its ends and moves relative to the bearing surface in response to a bending of the elastic member. The apparatus may be tuned to effectively isolate a particular vibration frequency, for example, by altering the properties of the elastic member or by changing the distance between the points on the bearing support that engage the elastic member.
