Abstract:
A frame hanger including a frame bracket adapted for connection to a vehicle frame rail, a spring box attached to the frame bracket, a vertically extending gusset attached to the frame bracket and positioned within the spring box to form a first spring module and a second spring module, where the spring box provides a bottom wall, a top wall, and an outer side wall of the first spring module, and where the spring box provides a bottom wall, a top wall, and an outer side wall of the second spring module, and the vertically extending gusset provides an inner side wall of the first spring module and an inner side wall of the second spring module.
Abstract:
An axle/suspension system for a heavy-duty vehicle with a pair of suspension assemblies which each are mounted on a hanger outboardly offset from the outboard surface of the vehicle main member from which it depends. Each suspension assembly includes a beam pivotally attached to the hanger outboardly offset from the outboard surface of the main member. The beam has a tapered profile including an upward outboard taper on at least the inboard side of the beam, which provides clearance between each beam and its respective vehicle main member during upward jounce travel or lifting of the axle/suspension system.
Abstract:
A frame hanger having a frame attachment portion having a first mounting surface and a second mounting surface, a first control arm mounting portion positioned beneath the frame attachment portion, wherein a first plurality of elongated longitudinally extending slots extend through the first mounting surface of the frame attachment portion, and wherein a second plurality of elongated longitudinally extending slots extend through the second mounting surface of the frame attachment portion.
Abstract:
A cross arm bushing assembly for use in a vehicle suspension is provided having a bushing with an outer surface adapted for rotation with respect to an end of a control arm, a cross arm assembly positioned within the bushing that includes a cross arm having a first end and a second end, and a front side and a back side, the first end of the cross arm having a first opening for receiving a first connecting rod, and the second end of the cross arm having a second opening for receiving a second connecting rod, a first connecting rod extending into the first opening of the cross arm, and a second connecting rod extending into the second opening of the cross arm.
Abstract:
A clamp group for a vehicle leaf spring suspension is disclosed. The clamp group secures a longitudinally disposed, leaf spring at separate and distinct locations, between which the leaf spring is undamped and spaced away from the top and bottom pads of the clamp group. Shear stress is reduced and the spring remains active throughout its length.
