The invention discloses an additional brake which comprises a driving chain wheel, a brake disc, a pressing disc, a brake block and a triggering component. The brake disc is arranged between the driving chain wheel and the pressing disc which is pressed on the brake disc, and the pressing disc is connected with the driving chain wheel through a locking component. A protruding block is arranged on the brake disc. The brake block is connected with the triggering component. The brake block and the protruding block are kept in a meshing or separate state through action of the triggering component. According to the additional brake, during braking, the brake block and the protruding block are controlled to be meshed through the triggering component, so that the brake disc is kept static, the driving chain wheel and the pressing disc move relative to the brake disc respectively under the effect of inertia force, finally braking is achieved through kinetic friction force generated on a matching face, when braking is not carried out, the triggering component controls the brake disc to be separated from the protruding block, under the effect of the locking component, the driving chain wheel, the brake disc and the pressing disc operate synchronously, and the additional brake has the advantages to being simple and compact in structure, convenient to arrange and adjust, low in cost, high in assembling efficiency and the like.

A system and method are provided for continuous monitoring and controlling of aircraft braking that can reduce brake wear and aircraft operating costs through the retention of carbon brake powder from the brakes or addition of carbon powder in a device mounted with respect to the brake disc stack. The use of carbon powder reduces brake wear by providing small particles between the brake discs, acting as a buffer between the brake discs when the brake stack is clamped together. Moreover, when carbon powder or small particles are used at application, such use reduces the roughness of the carbon surface and reduces the number of large particles from braking off the carbon surface, thereby reducing brake wear. Adaptive or selective braking may be used in conjunction with carbon powder to further reduce carbon brake wear.

The invention being presented uses the motors already included in an electric vehicle to charge its batteries while in tow. The charging process provided by the invention is compatible with the charging speed of current battery technology. It will provide an effective way of charging vehicles in theater, when other sources of electrical energy may not be available.Moreover, the proposed system can actually extend the brake life of the towing vehicle and improve performance boundaries of the overall system.

The invention discloses a preparation method and application of a carbon-ceramic friction material. The preparation method comprises the following steps: 3 The C / C composite material is a green body that undergoes PIP treatment, high temperature treatment, and RMI treatment in sequence to obtain a density of 1.9‑2.2g / cm 3 carbon-ceramic friction material; the RMI treatment process is to place the high-temperature-treated green body in a graphite mold paved with silicon powder and amorphous silicon carbide powder, and under vacuum conditions, the siliconization reaction, the non- Shaped silicon carbide powder is obtained by sintering silicon carbide ceramic precursors at 800-1000°C. The carbon-ceramic friction material prepared by the method of the present invention adjusts the particle size gradation and content of different silicon carbides in the material, and the obtained friction material has an adjustable and stable friction coefficient, a small amount of wear, no obvious vibration during the braking process, and the braking curve is rectangular. , stable, no tail warping, no large attenuation in the wet state after friction, suitable for brake discs required for the braking of aircraft, automobiles, heavy trucks, high-speed trains and other transportation systems.
