A brake device for installation on an axle of wheels including a piston; a casing accommodating at least the piston; a container; a first cast iron disc and a second cast iron disc, joined to the container; a first brake lining; a first supporting disc on which the first brake lining is located; and a bearing fixed to the central cylindrical wall of the container around the axle. The container and the casing remain fixed without rotating about the axle and the first brake lining together with the first supporting disc are fixed to the axle. The piston is further configured to displace the container together with the two cast iron discs towards the first brake lining until the first cast iron disc makes contact with the first brake lining. The container includes an inner circuit configured to accommodate a coolant.

A system, and associated method, for reducing oxidation of a friction disk may include a braking assembly comprising the friction disk and a coolant loop coupled to the braking assembly, with the coolant loop being configured to circulate liquid coolant from the braking assembly. That is, the coolant loop may be configured to reduce the temperature of the braking assembly, thus reducing the rate/extent of oxidation of the friction disks and potentially enabling the concentration of oxygen around the braking assembly to be reduced.

The flywheel device includes a sealed housing section; a rotor located in the sealed housing section where the rotor is held in a vertical position by a magnetic system; a controller coupled to the magnetic system; and a braking annular ring mounted to the sealed housing section below the rotor, where the rotor contacts the braking annular ring when the rotor is lowered or otherwise dropped from the vertical position. The controller perform operations to provide control signals to provide first power to the magnetic system to hold the rotor in the vertical position and provide second control signals to provide second power to the magnetic system to lower the rotor.

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.

A braking system for a road vehicle having: a brake disc; a brake caliper provided with at least one hydraulic piston; a hydraulic circuit containing a brake liquid and having: a hydraulic control unit provided with an electrically controlled pump and a delivery pipe, which connects the hydraulic control unit to the hydraulic piston; a return pipe, which is separate from and independent of the delivery pipe and connects the hydraulic piston to the hydraulic control unit; a recirculation solenoid valve, which is interposed along the return pipe and can be controlled so as to enable or forbid the circulation of the brake liquid along the return pipe; and a control unit, which, when the braking system is not used, opens the recirculation solenoid valve and operates the electrically controlled pump so as to create a circulation of the brake liquid through the first delivery pipe and through the return pipe.
