An axle system and a method of assembly. The axle system may include an axle lift kit. The axle lift kit may have a first bracket subassembly that may be fastened to the hanger bracket and a second bracket subassembly that may be fastened to first and second lateral sides of the trailing arm.

Axle system having an axle lift kit and method of assembly

A shear bolt and an axle suspension system having a shear bolt. The shear bolt may have a shear head and an enlarged head. The shear head may be configured to detach from the shear bolt. The enlarged head may have first and second protrusions that may be grasped by a tool in a manner that prevents tightening of the shear bolt.

Axle suspension system having a shear bolt

An axle suspension system and a method of manufacture. The axle suspension system may have an axle, an axle wrap, and a weld seam. The axle wrap may receive the axle and may have a first end portion and a second end portion that overlaps the first end portion. A weld seam may couple the first end portion to the second end portion.

Axle suspension system having an axle wrap and method of manufacture

An axle suspension system and a method of manufacture. The axle suspension system may include a trailing arm assembly disposed on an axle wrap. The trailing arm assembly may include a lower portion and an upper portion. The lower portion may have a lower intermediate wall. The upper portion may be fixedly disposed on the lower portion and may have an upper intermediate wall. The lower intermediate wall and upper intermediate wall may be spaced apart from the axle wrap.

Axle suspension system and method of manufacture

An axle suspension system for a vehicle. The axle suspension system may have a cam bracket that may be disposed on an exterior surface of an axle. The cam bracket may extend through a weld window of an axle wrap.

Axle suspension system

An axle suspension system for a vehicle. The axle suspension system may include a trailing arm assembly that may have a shock absorber passage. A shock absorber may extend through the shock absorber passage.

A trailing arm suspension includes a trailing arm body having an axle mount portion that is attached to an axle wrap. The axle wrap includes at least one internal weld window to secure the axle wrap to an axle. In one example, the internal weld window is positioned within an internal cavity defined by the trailing arm body and axle wrap includes an external weld window located external of the trailing arm body. In one example, the trailing arm suspension includes a reinforcement bracket that is attached to both the trailing arm body and the axle wrap. In one example, a spring pedestal includes a support plate at one end of trailing arm body and a side wall portion that extends downwardly from the support plate to be attached to the axle wrap. In one example, the axle wrap includes a weld window having a V-shaped lower edge surface.

Top mount trailing arm suspension

A trailing arm assembly for a suspension includes at least first and second cast components. The first and second cast components are welded to each other to substantially surround an outer perimeter of an axle member. The first cast component is then welded to one side of the axle member at a first weld and the second cast component is welded to an opposite side of the axle member at a second weld. One of the first and second cast components includes an integrally formed air spring seat and the other of the first and second cast components includes an integrally formed bushing housing for connection to a frame.

Cast trailing arm assembly for trailer suspension

A trailing arm assembly for a suspension includes first and second axle wraps. The first and second axle wraps are welded to each other to substantially surround an outer perimeter of an axle member. The first axle wrap is then welded to one side of the axle member at a first weld area and the second axle wrap is welded to an opposite side of the axle member at a second weld area. The first axle wrap includes a spring seat and the second axle wrap includes an arm body with a bushing receiver portion at one arm end. A bushing tube attached to the bushing receiver portion. The first weld area comprises a single window weld and the second weld area comprises first and second window welds that are positioned on opposing sides of the arm body.

The first and second cast components are welded to each other to substantially surround an outer perimeter of an axle member. The first cast component is then welded to one side of the axle member at a first weld and the second cast component is welded to an opposite side of the axle member at a second weld. A bushing tube is then welded to one of the first and second cast components and is subsequently attached to a vehicle frame member. The first weld area comprises a pair of laterally spaced window welds and the second weld area comprises a single window weld.

A tractor-trailer slider includes spaced apart longitudinal side rails having control arm supports extending downwardly from the side rails for supporting the slider. Portions of the longitudinal side rails and the control arms supports are integrated using one or more common plates. Lightening holes and edge of the slider are flanged to reinforce the walls. Coining and ribbing are also used for additional reinforcement. Lateral cross-members extend between the longitudinal side rails. The lateral cross-members have tabs on opposing ends that are received in an interlocking relationship with complementary elongated slots in the longitudinal side rails. Air spring supports arranged at forward and rearward portions of the slider are secured to the longitudinal side rails, the control arm supports, and the lateral cross-members to provide a structurally rigid frame. The air spring supports provide spaced apart air spring mounting pads.
