Abstract

In some examples, a brake assembly is configured to compress a brake disc stack to reduce and/or limit rotational motion of a wheel about a wheel axis. The brake assembly is configured to transmit a compression force on the disc stack to a backing plate. The backing plate is configured to transmit the compression force to a torque tube via one or more torque pads. A torque pad includes a pin supported by a support portion of the torque pad. The pin is configured to insert into a support recess of a boss when the boss supports the torque pad. The support portion of the torque pad is resiliently biased, such that the support portion exerts an force on the pin in an inward direction when the pin is displaced in an outward direction opposite the inward direction.

First claim

What is claimed is:

1 . A torque pad comprising:
a pad body defining a front portion and a back portion opposite the front portion, the front portion defining a pad face configured to engage a backing plate of a braking system, wherein the back portion defines a first support portion and a second support portion separated from the first support portion, wherein the first support portion and the second support portion are configured to receive a boss of the braking system such that the boss supports the pad body, wherein the first support portion supports a first pin configured to insert into a support recess of the boss when the boss supports the pad body, wherein the first support portion is resiliently biased to exert a force on the first pin in a direction toward the second support portion when the first pin is displaced in a direction away from the second support portion, and wherein the pad body defines a tab configured to displace the first pin in the direction away from the second support portion in response to a force in the direction away from the second support portion is applied to the tab.

2 . The torque pad of claim 1 , wherein the first pin extends from the first support portion to a first pin free end, wherein the first pin free end is configured to position within the support recess when the first pin is inserted into the support recess and the boss supports the pad body.

3 . The torque pad of claim 1 , wherein the second support portion defines a second pin configured to insert into a second support recess of the boss when the first pin is inserted into the support recess and the boss supports the pad body.

4 . The torque pad of claim 3 , wherein the first pin extends in a first direction from the first support portion to a first pin free end, and wherein the second pin extends in a second direction from the second support portion to a second pin free end, wherein the second direction is opposite the first direction.

5 . The torque pad of claim 1 , wherein the pad body defines a boss recess between the first support portion and the second support portion, and wherein the boss recess is configured to receive the boss when the first pin is inserted into the support recess and the boss supports the pad body.

6 . The torque pad of claim 1 , further comprising:
a torque tube defining the boss, and the backing plate, wherein the pad body is configured to insert into a backing plate pocket defined by the backing plate when the first pin is inserted into the support recess and the boss supports the pad body.

7 . The torque pad of claim 1 , wherein the first support portion includes a ligament including a first end attached to the pad body and a second end attached to the first pin, wherein the ligament is configured to exert the force on the first pin in the direction toward the second support portion when the second end is displaced relative to the first end in the direction away from the second support portion.

8 . The torque pad of claim 1 , wherein the pad body defines a back face between the pad face and the first pin, wherein the first pin is configured to move relative to the back face when the first pin is displaced in the direction away from the second support portion.

9 . The torque pad of claim 1 , wherein the second support portion defines a second pin configured to insert into a second support recess of the boss when the first pin is inserted into the support recess and the boss supports the pad body, and wherein the first pin is configured to displace in a direction away from the second pin when the first pin is displaced in the direction away from the second support portion.

10 . The torque pad of claim 1 , wherein the back portion defines a back face configured to transmit a force from the backing plate to the boss when the boss supports the pad body and the backing plate exerts the force on the pad body.

11 . The torque pad of claim 10 , wherein the pad body is configured to transmit at least some portion of the force over a compression axis extending through the pad face and the back face, and wherein the back face defines a convex surface intersected by the compression axis.

12 . The torque pad of claim 10 , wherein the pad body defines a pad boundary defining a pad recess configured to receive the boss when the first pin is inserted into the support recess and the boss supports the pad body, and wherein the pad boundary surrounds at least some portion of the back face.

13 . The torque pad of claim 12 , wherein the pad boundary supports at least one of the first support portion or the second support portion.

14 . The torque pad of claim 12 , wherein a portion of the pad boundary defines at least one convex surface configured to engage the boss when the first pin is inserted into the support recess and the boss supports the pad body.

15 . A torque pad comprising:
a pad body defining a front portion and a back portion opposite the front portion, the front portion defining a pad face configured to engage a backing plate of a braking system and a back face opposite the pad face, wherein the back portion defines a first support portion and a second support portion separated from the first support portion, wherein the first support portion and the second support portion are configured to engage a torque tube boss of a torque tube such that the torque tube boss supports the pad body, wherein the first support portion defines a first pin configured to insert into a support recess of the torque tube boss when the torque tube boss supports the pad body, wherein the second support portion defines a second pin configured to insert into a second support recess of the torque tube boss when the torque tube boss supports the pad body, wherein the first support portion is resiliently biased to exert a force on the first pin in a direction toward the second pin when the first pin is displaced in a direction away from the second pin, and wherein the first pin is configured to move relative to the back face when the first pin is displaced in the direction away from the second pin.

16 . The torque pad of claim 15 , wherein the pad body defines a tab configured to displace the first pin in the direction away from the second pin when a force in the direction away from the second support portion is applied to the tab.

17 . The torque pad of claim 15 ,
wherein the first support portion defines a ligament including a first end attached to the pad body and a second end attached to the first pin, wherein the ligament is configured to exert the force on the first pin in the direction toward the second support portion when the second end is displaced relative to the first end in the direction away from the second support portion, and wherein the ligament is configured to move relative to the back face when the first pin moves relative to the back face.

18 . A method comprising:
exerting, using resilient biasing of a first support portion of a back portion of a torque pad, a force on a first pin supported by the first support portion in a direction toward a second support portion of the back portion, wherein the first support portion exerts the force in the direction toward the second support portion when the first pin is displaced in a direction away from the second support portion; inserting, using the force on the first pin, the first pin into a support recess of a boss of a brake assembly, wherein the torque pad includes a pad body defining the back portion and a front portion opposite the back portion, the fr
