A hybrid torque tube for a brake assembly may comprise a tube portion having a centerline axis, and a conical back-leg portion extending from the tube portion.

In some examples, a brake assembly includes a torque tube supporting a plurality of splines including a first spline and a second spline. The first spline has a first stiffness and the second spline has a second stiffness greater than the first stiffness. The braking system is configured such that, during a braking event and/or other relative motion between the stator disc and the torque tube, the first spline contacts the stator disc prior to the second spline, such that the first spline deflects and/or otherwise deforms before the stator contacts the second spline.

A braking device for a vehicle may have a disc with a disc body with at least one connection portion. The connection portion having at least one arm, which projects cantilevered. The arm has a free terminal end and an attachment root. The root has at least one contact area of an elastic element with seat walls. The at least one arm has at least one working portion which touches the engagement portion of a bush and affects the bush to abut against a dragging surface.

A floating disc brake assembly having a disc brake rotor secured to a mounting assembly, such as a hat or a hat with a retention ring structured and arranged to fit within retention ring flanges of a plurality of rotor mounting tabs uniformly distributed about the mounting assembly.

The securing ring secures the friction ring on the brake disk hat in the axial direction. The securing ring includes a number of spring elements which are spaced apart from one another in the circumferential direction of the securing ring.

A torque tube for a brake assembly may include a tube portion having a first centerline axis, a conical back-leg portion extending from the tube portion in a radially outward angled orientation relative to the first centerline axis, and a lip portion disposed at a radially outward end of the conical back-leg portion. The lip portion may have added structural material to improve the structural properties of the torque tube to prevent or mitigate damage that would otherwise be caused by friction-induced vibrations.

A brake disc-hub connection is provided, wherein a hub has drivers, which extend from a wheel flange of the hub in the axial direction relative to a rotational axis common to a brake disc and the hub and engage in a toothed manner between supporting elements, which are arranged on the inner circumference of a brake disc and extend in the direction of the rotation axis. Lateral flanks of the drivers are oriented radially to the rotation axis and lateral flanks of the supporting elements are oriented parallel to the lateral flanks of the drivers. The lateral flanks of each of the drivers are oriented at an angle of 15? to 30? to each other.

A brake stack comprises a stator having an annular, inner periphery section disposed substantially along a first radial plane extending normal to an axis of a wheel, and a stator side wall having a first stator contact surface, the first stator contact surface including a sloped portion which deviates away from the radial plane defined by the annular, inner periphery section. The brake stack further comprises a rotor having an annular, outer periphery section disposed substantially along a second radial plane extending normal to the axis of the wheel, and a rotor side wall having a first rotor contact surface shaped complementary to the first stator contact surface, wherein the stator and the rotor are interleaved. A brake disk may comprise a first radius of a friction surface at a first axial position and a second radius of the friction surface at a second axial position, where the first radius is different than the second radius. The brake disk may further comprise an axis of rotation orthogonal to a plane of rotation, wherein the brake disk rotates substantially in the plane of rotation, and wherein the friction surface is at an acute angle to the plane of rotation. An aircraft brake system comprises an aircraft rotor oriented orthogonally with respect to an axis of rotation and an aircraft stator configured to nest with the aircraft rotor, where a stator friction surface is non-orthogonal to the axis of rotation. The aircraft brake system may further comprise a pressure plate and an end plate configured to nest with the aircraft rotor and/or aircraft stator, and an actuator may be utilized to effectuate braking of the aircraft braking system.

A floating disc brake assembly, and method of assembly, comprising a disc brake rotor comprising an outer friction ring, an inner circumferential flange having a plurality of rotor tabs spaced about the flange and a circumferential groove about the inner circumferential flange, a hat comprising a cylindrical axial body, an outer circumference, a rotor mounting flange extending radially about the outer circumference and having a plurality of rotor mounting tabs spaced about the rotor mounting flange and forming slots interspersed therebetween structured and arranged for receiving the rotor tabs, and a circumferential groove about the outer circumference of the axial body, structured and arranged to align with the circumferential groove of the disc brake rotor, and at least one expander ring structured and arranged to fit within the circumferential grooves of both the rotor and the hat.

A torque bar manufactured by an additive manufacturing process is provided. The torque bar may include a torque bar body made of more than one metallic material. The torque bar may also include a geometry that comprises one or more voids and one or more webs, as well as a varied geometry in the direction of a longitudinal axis. The torque bars can exhibit characteristics, such as vibration damping, tuned stiffness, and tuned bending resistance in order to enhance dynamic stability.
