<p>PURPOSE:To adapt for remote controlling with safety by generating a pressure equivalent with a stepping force in remote controlling by means of multiplying unit. CONSTITUTION:For the operation of remote controlling, the second multiplying unit 23 is provided to supply braking oil pressure to an input port 3 of a multiplying unit 2 for the generation of braking force, and connected with a master cylinder 25. To a relay valve 26 of the unit 23, an operating unit 27 is added to operate the relay valve 26 emergently by remote control. The operating unit 27 that operates the relay valve 26 electrically by remote controlling can make use of an electromagnetic wave or a wireless controlling means. Signals from a transmitter 37 are received by a receiver 39 for switching over an electromagnetic valve 38. In the case of a driver school car, the valve 38 can be operated by a brake pedal to be stepped by a trainee.</p> |
