A brake assembly for landing gear of an aircraft includes a caliper member and a carrier member. The caliper member includes a gas inlet configured to receive a cooling gas supplied by an on board fuel inerting gas supply system of the aircraft, and a manifold fluidly coupled to the gas inlet. The manifold is configured to distribute the cooling gas to one or more outlet ports of the caliper member. The carrier member is configured to be coupled to the caliper member. The carrier member includes a cylindrical section configured to receive a stacked arrangement of stators and rotors. The cylindrical section defines one or more interior passages configured to fluidly couple the outlet ports of the caliper member to one or more outlet ports of the cylindrical section. The outlet ports of the cylindrical section are arranged proximate the stacked arrangement of stators and rotors to facilitate forced convective cooling of the stacked arrangement of stators and rotors with the cooling gas supplied by the on board fuel inerting gas supply system.

A system for use in connection with a wheel torque generating component in a heavy-duty vehicle, comprising a fluid conduit, a flow creating device configured to provide a pressurized air flow through the fluid conduit, a flow directing device enabling the pressurized air flow to be directed from the fluid conduit to the wheel torque generating component so as to control the temperature of the wheel torque generating component, and a control unit configured to compare a determined first temperature of the pressurized air flow with a determined second temperature of the wheel torque generating component, wherein the control unit is configured to, based on the comparison of the first temperature and the second temperature, selectively control the flow directing device to direct the pressurized air flow to the wheel torque generating component. The invention also relates to a method.

Systems and methods for aircraft brake cooling are described. A system may include an air hose configured to intake pressurized air at a first end of the air hose from an aircraft propulsor. A nozzle at a second end of the air hose may be configured to exit the pressurized air through the air hose to a braking system. An actuator may be configured to allow the pressurized air to flow through the air hose or prevent the pressurized air from flowing through the air hose.

An automatic transmission includes: a multi-disc brake including first and second friction engagement elements which are alternately arranged in an axial direction, and a tube that supplies lubricating oil to the first friction engagement element and the second friction engagement element in a transmission case. Further, the tube has injection holes that inject the lubricating oil toward a spline groove, which is fitted with spline teeth of the first friction engagement element on an inner peripheral surface of the transmission case, and the injection holes open toward a gap, which is formed between the spline groove and the spline teeth, and inject the lubricating oil to cause the lubricating oil to contact a surface of the spline groove located above the spline teeth.

A vehicle brake cooling system is provided. The vehicle brake cooling system is configured to actively cool brake elements affecting one or more wheels of the vehicle during the periods of vigorous or prolonged application of a vehicle's brakes to prevent overheating. The system is filled with a suitable coolant fluid which is pressurized to flow through a nozzle or a system of nozzles onto a brake element during active braking, cooling the brake element. Manual or automatic operation is disclosed, including use of temperature or pressure sensors. A method of use of a vehicle brake cooling system is also disclosed.

Methods are provided for optimizing usage of water harvested or generated on-board a vehicle. An amount of water selected for injection or spraying purposes, as well as an order of water injection responsive to various vehicle operating conditions, is varied based on the amount of water to be delivered, as well as a current water level relative to a predicted future water level. The method allows water usage benefits to be maximized particularly when water availability is limited.

A disc brake and a cooling controller, a control system and a control method, a brake disc of the disc brake includes a first basic plate and a second basic plate, jointed and forming a cavity. A fibrous body having a capillary structure is sandwiched between the first basic plate and the second basic plate, the fibrous body filling between the first basic plate and the second plate, and the fibrous body being formed in a ring shape and sleeves on an axle to receive cooling water from the axle and distribute the cooling water on inner walls of the first basic plate and the second basic plate. The cooling water is evenly distributed to prevent brake disc from fading under heat, and based on the disc brake, an additional automatic controlled cooling control system is provided to accurately control the amount of the cooling water, thereby saving water.
