IPC: F16D55/14
Filed: 1976-07-20
Abstract: The brake consists of a rotating housing (8) which is attached to the wheel rim (7) and which carries two brake rings (14, 15). The brake housing is mounted on a hub (4) which can rotate on roller bearings on the steering knuckle (1).

Title: Pulse width control of DC regulating unit - involves determining pulse width intersections of two sawtooth voltages with DC voltage and uses bridge circuit
Inventor: WOELLAUER ARNO
IPC: H02P7/29
Filed: 1977-06-29
Abstract: Transistors operating as convertor rectifiers in a single phase bridge supply a resistive-inductive load in the bridge diagonal. The duration of control pulses for the control circuits of two diagonally opposite transistors is determined by the points of intersection of a periodic saw-tooth voltage with a control d.c. voltage. Two synchronised, identical in shape, saw-tooth voltages shifted w.r.t. each other in the voltage axis direction, are made to intersect with a d.c. voltage. The end of each control pulse (IR1) for the transistors (T1, T2) on the first diagonal is separated from the beginning of each control pulse (IR2) for the transistors (T3, T4) on the second diagonal by fly-back time of the saw-tooth voltage. The end of the latter pulse (IR2) is separated from the beginning of the former pulse (IR1) by the time difference between the points of intersection of the least steep edge of the two saw-tooth voltages with the d.c. voltage.
