摘要： PURPOSE: To monitor the shortage of the air brake force of a trailer vehicle when the brake force of the trailer vehicle is not covered by electric brake force by constituting or releasing a circuit for checking the shortage of the brake force of the trailer vehicle according to whether the trailer vehicle is covered by the electric brake force or not. CONSTITUTION: A brake command e1 is outputted according to the control input 1a of the brake of a motor vehicle, and a reference brake force generator 3 generates the brake force signals e4, e5 and an addition organizing brake force signal e2 required for the load compensating devices 2, 20 of a trailer vehicle. An electric brake device 4 generates an electric brake force equivalent signal e3. A computing unit 25 inputs a first and a second monitoring signals e10, e11 to relays 14, 19. It outputs supplementary air brake command signals e8, e9 of the motor vehicle and the trailer vehicle. Brake monitoring devices 13, 28 are operated by the first and the second monitoring signals e10, e10 of the computing unit 25 to monitor the presence of an electric brake, and air brake devices 6, 21 of the motor vehicle and the trailer vehicle are operated according to the shortage of a brake.

摘要： PURPOSE:To provide a loading system in which malfunction can be prevented as much as possible even if a regular loading signal is not outputted due to failure of some air spring, pneumoelectric converter, or the like. CONSTITUTION:Air pressures AS1, AS2 from a plurality of air springs are converted through a pneumoelectric converter 8 into electric signals which are then outputted as loading signals for brake command or powering command. In such loading unit 21 for rolling stock, the signal fed from the pneumoelectric converter 8 is compared with a prescribed value 24 through a comparing means 23 which outputs a signal if the signal deviates from the prescribed value. The loading unit 21 further comprises selecting means R1, R2, R1c, R2c for switching the output from the pneumoelectric converter 8 to the output from the pneumoelectric converter 8 for other air spring.

摘要： PURPOSE:To cancel pressure shortage caused when pressure in a main air reservoir goes down to the lowest limit set pressure or lower, by accumulating a regenerated air reservoir after the main air reservoir is accumulated at the time when an air compressor operates. CONSTITUTION:A dehumidifying part 5, a check valve 9 and a main air reservoir 10 are serially connected to each other. A regenerated air reservoir 8 is connected to a passage between the dehumidifying part 5 and the check valve 9 through a branch passage with a restrictor 7, and this regenerated air reservoir 8 is connected to a primary side passage of the check valve 9 through a directional control valve 21. The directional control valve 21 comes to be in the communicating position when air pressure of the primary side of the check valve 9 is equal to or higher than the lowest limit set pressure of the main air reservoir 10 and reaches a specified pressure lower than the upper limit set pressure.

摘要： PURPOSE:To obtain an antiskid unit for achieving readhesion positively even upon duration of instable state where the direction of wheels is not settled even upon cessation of skid. CONSTITUTION:The antiskid unit 20 for vehicle comprises a skid detecting section 21 for detecting skid of wheel to produce a brake force decreasing signal (a), a skid cessation detecting section 22 for detecting cessation of skid to produce a brake force sustaining signal (b), and a recovery detecting section 23 for detecting eventual recovery of wheel speed to produce a brake force reset signal (c). A time interval after provision of the signal (b) from the skid cessation detecting section 22 before provision of the signal (c) from the recovery detecting section 23 is then measured and when the time interval thus measured exceeds a set time, a signal (e) is delivered from a timer circuit 25 to a circuit 26 for forcibly reducing brake force.

摘要： PURPOSE: To make up for the storage of electric braking force and to prevent the number of parts from increasing by computing/outputting a supplementary fluid braking force command signal for every trailer car, based on the total sum of a braking force command signal for every car of a trailer car and a braking force sharing signal from an individual trailer can belonging to the trailer car. CONSTITUTION: In a supplementary braking force computing part 21 of a trailer car Ta, a sum of (braking force) sharing signals X1, X2 from two individual trailer cars belonging to this trailer car Ta is deducted from a trailer car braking force command signal Fta of the trailer car Ta, and the difference is outputted as a supplementary fluid command signal Gta to a fluid braking device 27. On the other hand, in a supplementary braking force computing part 22, a sum of a sharing signal Y1 from an individual trailer car belonging to the trailer car Ta and another sharing signal Y2 from an individual trailer car belonging to another motor car is deducted from a trailer car braking force command force Ftb of this trailer car Tb, and the difference is outputted as a supplementary fluid braking force command signal Gtb to the fluid braking device 27.

摘要： PURPOSE: To make whole device construction simple and small by shutting off a capture command from a brake demand operating device to an electropneumatic change valve when the demand operating device or its power supply goes in failure, also actuating an emergency brake system, and supplying a pressure to a brake cylinder. CONSTITUTION: When a failure has arisen in a power supply or demand operating part 11 of a brake demand operating device 1 equipped with a monitoring circuit 2 followed by actuation of a plurality of sensors, normally closed contacts 16, 17 of a switch 6 are opened. A capture command F is separated from an electropneumatic change valve 5 and its output nullifies. An emergency brake command E2 is shut off to actuate application of an emergency brake, and specified pneumatic pressure for emergency brake is fed to each brake cylinder BC1-BC4. Further a demand operating device normal signal N to a coast preventing device 21 nullifies. Thereby a backup brake force is generated by a simple control method using an existing emergency solenoid valve EBV and coast preventive valves SV1-SV4, which allows simplifying the configuration of a backup brake controlling circuit.

摘要： 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.

摘要： PURPOSE:To enable application of the adhesion of trucks or axles by computing braking force command signals for a front-side truck and a rear-side truck and by outputting them to control parts of an electric braking device. CONSTITUTION:Load signals of air springs AS1 and AS2 of front-side and rear-side trucks are inputted to truck load calculating circuits 54 and 55 of a braking force command part 52 and loads are calculated and inputted as variable load signals W1 and W2 to braking force command units 41 and 42. A braking signal is distributed in the ratio between the load signals W1 and W2 and, the variable load signals W1 and W2 being added to the distributed braking commands, braking force signals F1 and F2 are outputted. Meanwhile, the variable load signals W1 and W2 are inputted to limiter circuits 44 and 45 and maximum adhesive braking forces of the trucks are calculated and outputted as equivalent signals H1 and H2. In lower-order priority circuits 46 and 47, priority is given to the lower in order of these signals and the command signals F1 and F2 and the signals given the priority are outputted to motor control parts 48 and 49 of an electric braking device 4. As the result, the adhesion of the truck or an axle on the higher-order side can be applied.
