Abstract
A torque plate barrel for use with a brake system is disclosed herein. The torque plate barrel includes a barrel body having an outer diameter, an inner diameter, and an axial length extending from a first end to an opposing second end, wherein the inner diameter varies along the axial length and the outer diameter is fixed along the axial length.
Claims13
A torque plate barrel for use with a brake system, comprising:
- a barrel body having an outer diameter, an inner diameter, and an axial length extending from a first end to an opposing second end, wherein:
- the inner diameter varies along the axial length and the outer diameter is fixed along the axial length,
- the varying inner diameter forms a taper that extends axially along an inner surface of the barrel body such that the inner diameter decreases from a first portion first point to a second portion first point and increases from the second portion first point to a back leg disposed at the second end of the barrel body,
- the barrel body has a first thickness at the first end and a second thickness at the second end,
- a first distance is defined as being between the first portion first point on the inner surface at the first thickness and a diametrically opposing first portion second point on the inner surface at the first thickness, and
- a second distance is less than the first distance and is defined as being between the second portion first point on the inner surface at the second thickness and a diametrically opposing second portion second point on the inner surface at the second thickness.

A brake assembly attached to a wheel, comprising:
- a torque barrel having an inner diameter and an axial length, the axial length having a first end and an opposing second end, the inner diameter decreasing along the axial length from the first end to the second end, wherein:
- the torque barrel has a first thickness at the first end and a second thickness at the second end,
- the varying inner diameter forms a taper that extends axially along the inner surface of the torque barrel such that the inner diameter decreases from a first portion first point to a second portion first point and increases from the second portion first point to a back leg disposed at the second end of the torque barrel,
- a first distance is defined as being between the first portion first point on the inner surface at the first thickness and a diametrically opposing first portion second point on the inner surface at the first thickness, and
- a second distance is less than the first distance and is defined as being between the second portion first point on the inner surface at the second thickness and a diametrically opposing second portion second point on the inner surface at the second thickness;
- a heat sink disposed around the torque barrel;
- and
- a plurality of stator disks mounted to the torque barrel.

A method of forming a torque plate barrel, comprising:
- receiving a torque plate barrel having a first end and an opposing second end, the torque plate barrel having an inner surface sidewall extending from the first end to the second end;
- and
- performing a tapering process to remove material from the inner surface sidewall, the tapering processing removing more material from the inner surface sidewall at the first end of the torque plate barrel than from the second end of the torque plate barrel, such that the tapering process forms a varying inner diameter, wherein;
- the varying inner diameter forms a taper that extends axially along the inner surface of the torque plate barrel such that the inner diameter decreases from a first portion first point to a second portion first point and increases from the second portion first point to a back leg disposed at the second end of the torque plate barrel,
- the torque plate barrel has a first thickness at the first end and a second thickness at the second end,
- a first distance is defined as being between the first portion first point on the inner surface at the first thickness and a diametrically opposing first portion second point on the inner surface at the first thickness, and
- a second distance is less than the first distance and is defined as being between the second portion first point on the inner surface at the second thickness and a diametrically opposing second portion second point on the inner surface at the second thickness.
