PURPOSE:To share the machines constituting a hydraulic brake system by inputting only a high level auxiliary hydraulic brake signal to a hydroelectric converting section and reducing the pressure of low level brake cylinder through an anti-slip valve while sustaining the pressure of high level brake cylinder as it is. CONSTITUTION:A brake command 35 from a brake commander 1 is combined with load signals WF, WR from front and rear truck brake power indicators 3, 4 in a brake command section 2 which then delivers front and rear truck brake signals FF, FR to low level preference circuits 14, 15 and adders 18, 19. The adders 18, 19 are also fed with output signals GF, GR from the circuits 14, 15 and a high level signal is fed, as it is, to a hydroelectric converting section 26 from a high level preference circuit 20 at an auxiliary brake regulating section 6. An auxiliary hydraulic brake unit 7 selects 23, 24 slip detection signals 44, 45 and supplies a reduced brake power to front or rear truck 31 or 32 through anti-slip valves 29, 30. Consequently, the auxiliary brake unit 7 can be shared. |
