Regenerative air brake module

Abstract: An air braking system for a vehicle blends regenerative and foundation braking during low deceleration conditions in an effective and controlled manner. The braking system also includes a mechanical override that bypasses system electronics in response to an aggressive brake request such that treadle circuit pressure is sent directly to a brake relay circuit to actuate vehicle brakes.

Method and apparatus for power management of a braking system

Abstract: A vehicle braking system and method of control is disclosed which includes electromagnetic and friction braking functionality. The electromagnetic braking system includes a generator which supplies power to eddy current devices. Accordingly, the eddy current devices apply a retarding torque on the wheels of the vehicle. In the event the generator is unable to supply a predetermined amount of power to eddy current devices, friction braking is activated thereby enhancing braking performance.

Braking capacity of railway wheels ─ state-of-the-art survey

Abstract: An overview of design methods for tread braking systems is given with special focus on the braking capacity of the wheels. Several aspects of the tread braking system, important for the dimensioning of railway wheels, are assessed, such as brake block materials, residual stresses and temperature gradients through wheel rim and wheel disc. The influence of heat partitioning between wheel, brake block and rail on wheel temperatures for different braking cycles is considered. Two examples with numerical results on thermomechanical behaviour of tread braking systems are given regarding the freight and metro applications.

Electronically-controlled electric drives in wheel hubs of electric vehicle for drive and braking, provides high torque during braking via planetary gear reducing revs of drive-motor for wheel hub

Abstract: An electronically-controlled electro-drive mounted in the wheel-hub of a motor vehicle for drive- and braking. The electric motors effect braking and the drive with a related control function for drive control together with drive dynamics control, traction control, anti-locking system, ride-stabilization and all-wheel drive carried out.
