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.
Claims18
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.
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.
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 front portion defining a pad face configured to engage a backing plate of the brake assembly;
- displacing, using a tab of the torque pad, the first pin in the direction away from the second support portion to insert the first pin into the support recess;
- and
- engaging the boss using the first support portion and the second support portion such that the boss supports the pad body.
