Sound indicator on hand brake with your own hands. Electrical diagram of manual brake signaling. Manual control of electropneumatic brake

The proposed device is designed to supply an intermittent sound and light signal to the driver when driving a car with a manual brake on. The diagram of its connection is shown on the example of the car "Moskvich-2140", but can be performed on other models of cars.

The device, the diagram of which is shown in the figure, consists of a sound generator collected on the transistors VT1, VT2, multivibrator on the transistors VT3, VT4 (Relay Winding K.1 is included in the VT3 collector circuit); Extra Switch SB2 and Standing Elements of Electrical Ignition Key SA1, SP SP SP GROUP HYDROPERVOD, SB1 switch of a manual brake lighting lamp and HL warning lamp.

The SB2 switch is set under the clutch pedal by analogy with the stop signal switch of the foot brake pedal. When you click on the clutch pedal, the contacts of the SB2 switch are closed when it is discharged.

Works device as follows. When the SA1 ignition lock is enabled, the +12 B power voltage is fed on the HL lamp and device terminal 5. Closing the SB1 switch contacts (manual brake on) The multivibrator and a warning lamp are connected to the negative circuit tire: minus 12 V, closed SB1 switch contacts, terminal 4 devices, normally closed contacts K1.1, switch SB2 and via VD1 diode on the HL diode . The multivibrator starts working.

Lamp and generator "give out" intermittent light and beep, respectively. When opening the contacts of the SB1 switch (manual brake is off), the lamp and the multivibrator are de-energized.

When the SP switch is triggered (the tightness of the hydraulic line is broken), the warning lamp will radiate the permanent light as usual with this malfunction. The indication of the manual brake state turned on when the clutch pedal is pressed, there will be an intermittent beep. This is achieved by separating the circuit of the SP switch and the negative power supply of the device on the included diode VD1, i.e. minus 12 V can only be supplied to the device 4 and the closure of the SP switch contacts does not affect the operation of the device.

The device is connected by terminals 1, 2 to the SB2 switch of the clutch pedal, terminal 3 to the contact of the SP switch freed from the conductor (a) (see Fig. 2). A disconnected conductor (a) of the SB1 switch is connected to terminal 4, terminal 5 to the power bus +12 V.

The correctly assembled and connected device does not need it in the configuration. All its elements are located on pCB and placed in a metal case.

Installation and interconnection of semiconductor elements are noncritical. Dimensions depend mainly on the type of relay and sound emitter used.

Long-term operation of the device showed its reliability, convenience and necessity.

PPZ, Machine Machine "Power Main", BCCCU KRO is set to "Forward" or "Back", a parking brake toggle switch to "Vacation". When the Vacation valve is triggered, the entire current passes through the chain of alarm in the BUV:

Resistance, diode, minus wire, which signals the buva on the vacation of the parking brake on the car. When you leave all parking brakes, the information on the Machinist monitor on the pressing of the parking brake disappears in the lines of information BUP and in.

If you do not leave the parking brake at least on one of the cars, in the BUP line information "Art. The brake is pressed "and in the mode of (wagon equipment), a red rectangle in the string" Art. Brake "remains.

With information "pressed Art. Brake "The" Vityaz "system gives the command" Prohibition of Movement "on the BUTP.

You can bypass the prohibition of Motion only when moving to the control of the train from the CBR. The alarm of the parking brake position controls the vacation of the parking brake, and the information about the pressing of the parking brake passes when the voltage is removed from the Vacation valve circuit.

Removing the voltage from the inclusion circuit "Vacation" will occur when:

Disabled (knocked) machines "Power Caps Main", "Power Caps Reserve";

Malfunctions of the keys of the BKCCU (CRO, CRR) "Forward" or "Back";

Losses of contact or malfunction of the Tumbler "Art. brake";

Fault circuit incorporating the valve "released".

Consequently, when the parking brake is turned on (pressed), it is necessary to check the actual pressing of parking brakes in the absence of a train roll after the vacation of pneumatic brakes.

ATTENTION! To disable the parking brake on any car in the event of a malfunction of the boom (the valve of turning off the parking brake) or not passing the command for shutdown, it is necessary to translate the handle of the C52 into the parking brake highway to translate from the "transport" position (tap handle) to the position "Emergency" (crane handle perpendicular to the highway), i.e. Rotate the handle by 90 °. This will lead to the cessation of air supply from N.M.V. Bust and air from N.M. Parking cylinder will go into the parallel air duct, the brake will turn off.

Scheme and operation of a security brake block (BTB), security loops

Manual control Electropneumatic brake

In normal mode of operation, on the carriages of the model 81-740.1, air pressure in TM 2.7-3.1 atm., The driver's crane is installed in the 6th position, the air distributors are in the brake position. Electric control is used to control pneumatic brakes, automatic and manual.

When switching to CRM, a pressure of 5 atm. In TM, the control of pneumatic brakes is made by a crane of the machine. About finding BP in the position of vacation signals:

In normal mode in the upper right corner of the machine monitor, the red letters "BTB";

In mode in the line "BTB GET" red square (s);

When the CRO or (CRP) is disconnected - large red letters of BTB on the screen monitor screen, as well as the absence of pressure in the shopping center.

When BP is in the position of leave and translating the TE in the "brake" position (disabling the reverse controller) there will be no "emergency brake". When controlling pneumatic brakes from the CRP, use the electropneumatic brake from the CTR button - is prohibited.

Turning on BTB and security hinge

75V voltage is supplied to the BTB: PPZ, included Machine Machine Machine or Cap Rubbing, Transistor keys Ut 4 or UT5 BCCCU, Open when CRO or KRN "Forward" or "Back", Contacts SD-115 included at the TM pressure of more than 2.7 atm. (With a malfunction, shunt an absorption of Abstracts), normally closed contacts with a disconnected position of the RTE toggle (backup Tumbler Emergency), BTB (converter), Barcor block (included in the position of Barç1 or Barc2), Bar keys included with good leopards, or contacts security pedals Position WOS, zero wire, BTB will receive food 75V (Fig.104).

When powering 75V, the BTB is obtained: the contactor K1 and the 50B converter. Enabled Ki, connects to the train 524 transistor key CL4, which is controlled by a microprocessor unit.

All cars include safety brake valves (WBT) on the chain:

Converter 50B, transistor key KL4, contacts K1.1, included Contacts TE header TEGON, 524 train wire, included Contmbers of the TE TEVER CONTROL WAGON, CONTACTS CONTRIBUTE, INCLUDED WITHOUT COP TAILS, 526 train wire, from wires 526 through VTB in each car on the wire 525, 0 in the voltage converter, Barcarator, Bars keys with ARS included, or PB when the WOS, 0V battery.

VTB valves are turned on, and turned off in the BEPP air distributors (located in the "brake") from the switch valves, which means from the RD (the air in the shopping center does not arrive).

Emergency brake turns on when:

Disabling the main or reserve controller;

Shutdowns of the machine "Power Caps Main" or "Power Caps Reserve";

Enabling TE or RTE togglers in the head or tail cabin;

Disconnecting the keys of the Bars;

Turning off PB when working in WOS mode;

When breaking the train.

Working TEBLER TE.

When you turn on the TE toggle in the control cabin or the tail cabin, the voltage is 50V with 524 and 526 train wires, VTB valves lose power, an emergency brake is turned on. BTB controls the voltage on the wires 524; 525; 526.

When the voltage is removed from 524, the microprocessor wire gives the command to shut down the KL4 key, which turns off the 524 wire from the converter (50B). To turn on the KL4 key, it is necessary to restart the microprocessor, for which it is necessary to remove and re-apply the voltage 75V, which is achieved by switching Cro (CRP).

Working Tumbler RTE

When turning on the RTE toggle:

RTE 1 contacts are opened, in the 75V VTB power supply circuit;

RTE 2 contacts are closed, connecting 526 and 525 train wires (the potential difference between the wires 526 and 525 becomes 0V, VTB is disconnected).

The inclusion of the RTE toggle is made by the machine in the case when the transition of the TE token to the brake position does not lead to an emergency brake triggering, which is possible with a stranger on a 526 wire.

Lamp and generator "give out" intermittent light and beep, respectively. When opening the contacts of the SB1 switch (manual brake is off), the lamp and the multivibrator are de-energized.

In tab. Figure 1 shows the status of indicators when the driver's drives are shown (SB1 switch) and the clutch pedal (switch SB2) when starting and moving the vehicle with a normal and disturbed tightness of the brake hydraulic.
The device is connected by terminals 1, 2 to the SB2 switch of the clutch pedal, terminal 3 to the contact of the SP switch freed from the conductor (a) (see Fig. 2). A disconnected conductor (a) of the SB1 switch is connected to terminal 4, terminal 5 to the power bus +12 V.

Hand brakes alarm

The driver's notification of the tightness of the hydraulic mechanisms of the wheels and the inclusion of the Moskvich-2140 car handheld brake is made using one signal lamp installed on the instrument panel. When the manual brake is turned on, the lamp lights up with a permanent light, which does not always attract the driver's attention, unlike the flashing, and often even experienced drivers forget to turn off the handbrake when starting and moving the car. This causes an increased wear of brake linings, an additional load on the engine and a violation of the adjustment of the handbrake drive system.
