A front diffuser for disposal in a region of an underbody cladding of a vehicle includes a diffuser wall defining a diffuser duct having an inflow side and an outflow side and an air guide device mounted so as to be rotatable about a predefined rotation axis and configured to, by way of a rotating movement, move from a first rotary position at least partially into the diffuser duct to a second rotary position and move from the second rotary position at least partially out of the diffuser duct to the first rotary position. The air guide device is configured as a molding and includes a first external face and a second external face.

A shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

The object of this disclosure is to cool the brakes of the landing gear of an aircraft. For this, it uses the air of the same air conditioning system of the airplane. The supply to the air conditioning system of the airplane can receive pre-conditioned air from outside by an air inlet in the lower part of the fuselage of the airplane to which an external equipment is connected. This air inlet has a non-return valve inside, which prevents the air from going outside. In order to extract the air from the air conditioning system of the airplane while it is on the ground, it is necessary to overpass the air valve. For this purpose, a tool that overpasses that valve from outside has been designed, and in this way, extracting and directing the air through connectors and tubes to the brakes, cooling them for a new takeoff.

Methods are provided for optimizing generation of water on-board a vehicle with reduced impact on fuel economy. Regenerative braking energy, and/or solar energy, in excess of what is required for charging a system battery, is used to operate a water extractor and save the captured energy as stored water. A proportion of the braking energy used to charge the battery versus operate the water extractor is adjusted as a function of operating conditions including a water level in a water reservoir on-board the vehicle.

A drum brake apparatus is provided for a vehicle air braking system. The drum brake apparatus comprises a wheel drum having a first interior chamber. The drum brake apparatus also comprises a drum brake assembly disposed in the first interior chamber of the wheel drum and mounted on inboard side of the wheel drum. The drum apparatus further comprises a brake drum adapter mounted on outboard side of the wheel drum and providing a second interior chamber in which an electric drive motor can be disposed. The drum brake apparatus also comprises a wheel hub disposed in the second interior chamber of the brake drum adapter and to which a wheel rim can be mounted.

An aerodynamic system for a wheel housing of a vehicle that according to one embodiment includes a flap that can be displaced between a deployed position and a retracted position, a rotating actuator, and a transmission mechanism coupled to the actuator and configured for transmitting the movement of the actuator to the flap. The aerodynamic system also includes at least one air flow shutter device in the wheel housing, where the shutter device faces at least one air duct and where the shutter device can be displaced between a closed position and an open position. The transmission mechanism is also configured for transmitting the movement of the actuator to the shutter device.

A pot-shaped composite brake rotor for motor vehicles, which combines at least one securing component as a hub interface with at least one friction ring component (as a friction partner for at least one friction lining. Distinction is made between a torque transmission function a fixing function between the paired components by the provision of a heat-conductive joint interface between the components on one side. The components are assembled coaxially with one another and joined rotationally fixedly in the axial direction so that the securing component serves as a heat sink for the friction ring component. At least one fixing element between the components is provided separately, and this fixing element substantially exclusively (nominal load) performs a fixing function by mutual form fit by a radially directed engagement behind at least one undercut. A press-fit connection s present for torque transmission between the securing component and the friction ring component.
