BRAKE SYSTEM FOR TRAVELING VEHICLE

摘要

PURPOSE:To provide an inexpensive brake system which can sustain a constant traveling speed at the time of descending a hill. CONSTITUTION:The brake system comprises a circuit 11 for detecting current I flowing through a DC motor 3, and an inverted amplifier circuit 13 for increasing/decreasing the exciting voltage of a solenoid 9 in the brake system 5 in proportion to increase/decrease of the current I thus detected.
