Patent ID: 7976110

Claim:
A wheeled vehicle having at least one non-drive axle and a braking system comprising: a foundation brake mechanism operably connected to wheels on a non-drive axle; a hybrid brake mechanism including an energy recovery machine operably mounted to the non-drive axle and being selectively actuable for connection to the non-drive axle in a braking mode for being driven by the non-drive axle to generate energy, and in a drive mode for transferring energy to the non-drive axle; an energy storage device for storing energy received from the energy recovery machine when the energy recovery machine is being operated in its braking mode, and for returning stored energy to the energy recovery machine to operate the energy recovery machine in its drive mode; and a controller operably connected to the hybrid brake mechanism for actuating the energy recovery machine selectively in its braking mode to receive energy from the non-drive axle, and in its drive mode for transferring energy to the non-drive axle only when the vehicle is in motion.
