Abstract
A rear axle beam for pivotally supporting a body frame of an industrial vehicle, including a boss-engaging areas formed on each end of the axle beam, and at least a pair of bosses, is provided. Each boss includes an axle-engaging area and is fixed to a respective end of the axle beam such that each axle-engaging area engages with a corresponding one of the boss-engaging areas. The novel axle beam reduces the force applied to weld beads between the bosses and the rear axle body of industrial vehicles.

A rear axle beam for pivotally supporting a body frame of an industrial vehicle, the axle beam comprising:
- a substantially rectangular vertical plate, wherein an upper corner of the vertical plate has a step;
- a horizontal plate attached to one edge of the vertical plate, wherein a recess is formed between an end of the horizontal plate and the step;
- a boss, wherein the boss has a substantially rectangular protrusion to fit in the recess, and the protrusion is welded to the vertical and horizontal plates.
A rear axle beam for pivotally supporting a body frame of an industrial vehicle, the axle beam comprising:
- a substantially rectangular vertical plate, wherein an upper corner of the vertical plate has a chamfered portion;
- a horizontal plate attached to one edge of the vertical plate, wherein a wedge-shaped recess is formed between an end of the horizontal plate and the chamfered portion of the vertical plate;
- a boss, wherein the boss has a wedge-shaped protrusion to fit in the recess and engage the vertical and the horizontal plates, and the protrusion is welded to the vertical and horizontal plates.
The rear axle beam for pivotally supporting a body frame of an industrial vehicle, the axle beam comprising:
- a substantially rectangular vertical plate, wherein an upper corner of the vertical plate has a notch;
- a horizontal plate attached to one edge of the vertical plate, wherein the horizontal plate is notched at its ends, wherein the notches form recesses;
- a pair of bosses, wherein each boss has a protrusion to engage in a corresponding one of the recess and the protrusion is welded to the vertical and horizontal plates.
A rear axle beam for pivotally supporting a body frame of an industrial vehicle, the axle beam comprising:
- a substantially rectangular vertical plate, wherein an upper corner of the vertical plate has a step;
- a horizontal plate attached to one edge of the vertical plate, wherein a recess is formed between an end of the horizontal plate and the step;
- a boss, wherein the boss has a protrusion to fit in the recess and engage the vertical and the horizontal plates, and the protrusion is welded to the vertical and horizontal plates, wherein the protrusion has a planar upper surface for engaging a planar lower surface of the horizontal plate, and the protrusion has a planar lower surface for engaging a planar upper edge surface of the vertical plate.
