Abstract
The present invention is directed to a torque rod comprised of a two piece mating design which increases rigidity and reduces the number of welds. Unlike other designs this design has single piece forged ends which permits the torque rod of the present invention to take greater payloads than other designs can take. The design further includes internal bearings.
Claims17
An apparatus for stabilizing a vehicle comprising:
- a male section including (1) an end portion attachable to a vehicle and with an internal sealed bearing assembly received therein and (2) a connecting portion with an alignment groove;
- and
- a female section including (1) an end portion attachable to a vehicle and with an internal sealed bearing assembly received therein and (2) a connecting portion with a single transverse opening;
- wherein said apparatus is formed by inserting said connecting portion of said male section into said connecting portion of said female section, aligning said alignment groove with said transverse opening, and subsequently welding said male portion to said female portion by forming only one weld plug in said transverse opening where said weld plug is applied in the visible portion of said alignment groove, and where said weld plug is the only attachment of said male section and said female section.
1 more element
A method for installing a two-section torque rod in a vehicle comprising the steps of:
- attaching a first section of a torque rod to the suspension of a vehicle, said first section comprising a first end portion with an internal sealed bearing assembly and a male elongated portion with an alignment groove, by attaching said end portion to a first torque rod bracket of said suspension;
- mating a second section of the torque rod with said first section, said second section comprising a second end portion with an internal sealed bearing assembly and a female elongated portion with a single transverse opening, said transverse opening allowing visibility with said alignment groove, by inserting said male elongated portion into said female elongated portion;
- aligning said alignment groove with said transverse opening;
- attaching said second section to the suspension of the vehicle by attaching said second end portion to a second torque rod bracket of said suspension;
- and
- welding said male elongation portion to said female elongated portion using only one weld plug in said transverse opening, where said weld plug is the only attachment of said alignment groove of said first section and said second section.
3 more elements
A torque rod comprising:
- a first section including (1) a hollow end portion for attaching to a vehicle with a first bearing assembly receiving therein and (2) a connecting portion with an alignment groove;
- a second section including (1) a hollow end portion for attaching to a vehicle with a second bearing assembly received therein and (2) a connecting portion with a single transverse opening in a channel for aligning with said alignment groove;
- wherein said apparatus is formed by the connecting portion of said first section being mated and aligned with the connecting portion of said second section by aligning said alignment groove with said transverse opening and subsequently welding said first section and said second section together with only one weld plug, thereby forming the only bond between said first section at said alignment groove and said second section at said transverse opening.
