A system for reducing a temperature of a braking assembly includes the braking assembly of a wheel assembly, an airflow amplifier, and a conduit. The braking assembly may include a plurality of friction disks. The airflow amplifier may be coupled to the wheel assembly, and the conduit may extend from a compressed gas source to the airflow amplifier. Generally, the airflow amplifier is configured to entrain ambient air (“entrained air”) in response to compressed gas from the compressed gas source flowing to the airflow amplifier via the conduit, according to various embodiments. The airflow amplifier may be configured to direct the entrained air and the compressed gas to the braking assembly to reduce the temperature of the braking assembly.

Disclosed is a method for capturing particles ejected by friction braking elements (2) of a braking system (1, 2) with disk brakes (1) of a vehicle. The braking system is equipped with a capture conduit (3) taking a form adapted to accommodate the friction braking elements (2) and to conduct, while the vehicle is moving, an air flow for cooling the friction braking elements, the conduit integrating a shutter (6) with a plate (6a) positioned upstream of the friction braking elements (2), and a unit (5) for capturing particles ejected by the friction braking elements (2). Furthermore, the shutter (6) is controlled so as to move the plate (6a) between a position of closing the conduit (3), set for vehicle travel speeds lower than a predefined threshold speed Vs, and at least one position of at least partially opening the conduit (3), for vehicle travel speeds higher than the threshold speed Vs.

A brake dust cover is installed in a brake system including a rotor disposed on an inner diameter side of a rim of a wheel and a caliper interposing and holding the rotor with brake pads and includes a main body, an extension, and an opening. The main body is disposed adjacent to the rotor on an inside of the rotor in a vehicle width direction, that is disposed so as to overlap at least a part of the rotor when viewed from an axle direction, and that is disposed such that an outer circumferential edge portion thereof is separated from an inner circumferential surface of the rim. The extension extends from a part of the outer circumferential edge portion of the main body to an outer diameter side. The opening is formed in the main body, and air in a wheelhouse is introduced toward the rotor through the opening.

The primary purpose of this device is to reduce the fuel consumption of heavy trucks by improving airflow along the underside of a trailer, by way of a fairing mounted forward of the axles. This fairing is a teardrop shaped wedge with a flat bottom surface, which directs air towards the sides of the vehicle, while allowing a smaller volume to flow beneath the fairing such that it will clear the axles. Each axle is also covered by a flat panel, such that air will continue to travel smoothly beneath them. Attached to each panel is a brake cooling system, which consists of a pair of panels protruding downward, with their surfaces parallel to the direction of airflow. When the brakes are engaged, these panels rotate towards the center in an angled configuration, which redirects air towards the drums during and after braking, cooling them quickly and efficiently.

According to one embodiment, a rotor brake includes a first braking surface having an opening therethrough, a second braking surface adjacent to the first braking surface, and an impeller disposed between the first and second braking surfaces such that rotation of the impeller pulls fluid through the opening of the first braking surface and expels the fluid out through a gap between the first and second braking surfaces.
