An All-Terrain Vehicle with a frame, a rear axle and at least a rear trailing arm. The rear trailing arm may attach to the vehicle frame frontward of the rear axle and may enter a wheel hub space partially frontwards of the rear axle and attach to an inset wheel hub. The rear trailing arm may have multiple tubular portions including a frame tubular portion and a wheel tubular portion. The frame tubular portion and wheel tubular portion are attached together at approximately 90 degrees. The wheel tubular portion has at least a distal portion that is configurated to encompass at least a partial length of an ATV axle and a proximal portion that is frontwards of ATV axle. The trailing arm provides clearance when the wheel hub is moved vertically by an angle of 27 degrees.

This disclosure relates to methods for obtaining a suspension arm for automotive vehicles, wherein certain embodiments comprise obtaining two identical parts to form a body, where each part is obtained by means of: a) cutting a metal or composite sheet forming a base plane, such that a central segment and two ends are defined, b) drawing at least one hole in each end, c) stamping each part forming in its central segment two flanges consisting of a first flange and a second flange located on opposite sides of the central segment and oriented perpendicular to the base plane, where said flanges have an asymmetrical arrangement with respect to a midplane passing through the geometric centers of the holes of the two ends and is perpendicular to the base plane, the second flange being separated from the midplane a distance equal to the separation of the first flange from the midplane plus a distance at least equal to the value of the thickness of the sheet or plate.

A fabricated torque arm for use in a vehicle suspension, including a rod having a solid rectangular cross-section, the rod having a first end and an oppositely disposed second end, a first bushing hub, and wherein the rod is only a single piece cut from a metal plate or sheet, wherein the first bushing hub comprises cut tubing, wherein the first end of the rod has a radius that conforms to an outer surface of the first bushing hub, and wherein the first end of the rod is welded to the outer surface of the first bushing hub.

Stepwise bending in the method for manufacturing a vehicle suspension arm includes a first bending step and a second bending step. In the first bending step, preliminary bending is performed while holding a portion that composes a base portion of a body portion and a portion that composes first coupling portions in a workpiece W by a punch (first punch). In the second bending step, while holding of the portion that composes the first coupling portions by the first punch is released subsequently to the first bending step, bending is performed along a fold given by the first bending step while holding the portion that composes the base portion of the body portion by a punch (second punch).
