In some examples, a drive insert comprises a first clip, a second clip, and a retainer. The first clip is configured to be slidable over a first surface adjacent to a first drive slot of a brake disc in a first tangential direction of the brake disc. The second clip is configured to be slidable over a second surface adjacent to a second drive slot of the brake disc in a second tangential direction of the brake disc. The retainer is configured to be slidable over the first clip and the second clip when the first clip and second clip are positioned one the brake disc secure the first and second clips to the brake disc.

Land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels, and an impact management system. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The frame structure includes a pair of rails that each extends in the longitudinal direction from a first end arranged adjacent a pair of front wheels to a second end arranged adjacent a pair of rear wheels. The plurality of wheels are supported by the frame structure. The plurality of wheels includes the pair of front wheels and the pair of rear wheels. The pair of front wheels are positioned forward of the pair of rear wheels in the longitudinal direction.

The invention relates to a bar spacer (10) for a braked aircraft wheel, the bar being for fitting to a rim (1) of the wheel in order to drive the rotor disks of the brake in rotation, the spacer being for interposing between the bar and the rim, the spacer comprising two bearing blocks (11) connected together by a core (15) that is pierced to pass a screw for fastening the bar to the rim. According to the invention, the bearing blocks (11) of the spacer include voids defining a void fraction of at least 30% of the volume of the bearing blocks.

A hybrid torque bar for a brake assembly may comprise a base portion, a pin extending from a first end of the base portion, and a rail extending between the first end of the base portion and a second end of the base portion opposite the first end. The base portion may be formed using a first manufacturing process. At least one of the pin or the rail may be formed using a second manufacturing process. The second manufacturing process may comprise an additive manufacturing technique.

In some examples, an assembly includes a rotor drive key configured to be positioned over a wheel boss defined by a wheel. A drive key body defines a trough configured to receive the wheel boss. An inner surface of the drive key body is configured to establish a conforming contact with an outer profile of the wheel boss and oppose relative motion of the rotor drive key in a radial direction of the wheel. The rotor drive key includes a tab having a tab aperture configured to receive a fastener extending in an axial direction of the wheel and engaging the wheel boss.

A combined wheel includes spokes, steel bushings, a rim, a metal frame, a brake disc and pins. In use, the steel bushings are installed in grooves of the spokes; the spokes are placed so that the clamping grooves are matched with the connecting blocks; the pins are installed into holes of the spokes and the connecting blocks; the metal frame is matched with the backs of the spokes; the screws I connect the metal frame, the connecting blocks and the spokes together and are matched with the steel bushings; and the brake disc is connected to the metal frame by screws II. In the combined wheel, the radial force and the axial force generated in the running process of the wheel can be counteracted on the spokes; and the brake disc brakes from the inside, thereby increasing the brake radius and reducing the clamping force required when braking.

In some examples, an assembly includes a rotor drive key configured to fit around a wheel boss defined by a wheel of a vehicle. The rotor drive key includes a support member. The assembly further comprises a fastener configured to extend through the wheel boss and the support member in a substantially axial direction of the wheel when the rotor drive key is fit around the wheel boss. A fastening member is configured to engage with a portion of the fastener extending beyond the support member.

A combined wheel includes spokes, steel bushings, a rim, a brake pad, pins and a backing ring. The spokes are placed in respective empty slots between adjacent connecting blocks, and clamping grooves therein are matched with the connecting blocks. The pins are installed into holes of the spokes and the connecting blocks. A left end face of a backing ring is matched with the back of the spokes. A plurality of screws connect the backing ring, the connecting blocks and the spokes and are fitted into the steel bushings. The brake pad is fixed to two pluralities of bosses by a second plurality of screws. In use of the combined wheel, both radial force and axial force generated in the running of the wheel can be counteracted on the spokes. The annular brake pad is installed on the inner wall of the rim, thereby increasing the brake radius.

A wheel assembly includes an inboard wheel portion having a rim and a disk. A radially inward surface of the rim and an inboard surface of the disk define a wheel well cavity configured to house a brake assembly. The wheel assembly also includes a torque bar (e.g., a torque bar of the brake assembly) mounted to the inboard wheel portion. Further, the wheel assembly includes a retainer coupled to the torque bar and disposed radially between the torque bar and the radially inward surface of the rim of the inboard wheel portion. The retainer includes a first end, a second end opposite the first end, and a body extending between the first end and the second end. The body includes opposing longitudinal sides configured to respectively engage and retain a respective heat shield segment of a segmented annular heat shield.
