  • Patent number: 4659149
    Abstract: A cross blending brake system for a multi-car train having power cars that provide regenerative braking through the electro-dynamic action of the car's traction motors, as well as friction braking through an electric/friction brake blending valve, and non-power cars that provide friction braking only through an electric/friction brake blending valve. Since the regenerative brake effort on the power cars is limited only by the available wheel to rail adhesion on these cars, the regenerative action of the electro-dynamic brake provides brake effort in excess of the power car brake requirement, thus reducing the friction brake requirement of the non-power cars, which is limited by the lower threshold energy absorption ability of the wheels. The cross blending control utilizes the excess power car regenerative braking to avoid overheated wheels, while at the same time realizing a net energy savings and reduced brake shoe wear, particularly at maximum levels of regeneration.
