Definitions
- the invention relates to a brake for trailers attached to a traction ⁇ motor vehicle, that is to say driveless vehicles according to the preamble of claim 1, both for road and rail vehicles.
- the braking forces are the braking forces that arise when the towing vehicle brakes by pushing the trailer. So that they are not actuated with every small pressure surge, overrun brakes are extremely inert. Especially when driving downhill and / or when braking heavy trailers, the behavior of the team can become uncontrollable even with overrun brakes.
- a trailer is known from US-A-3, 955, 652, which is designed according to the preamble of claim 1.
- the trailer has a brake which is actuated by a brake pressure regulator designed as an electrical amplifier.
- the amplifier is connected to the towing vehicle with a cable provided with a connector, which also supplies the brake light of the trailer. If the braking force is insufficient when the brake light is actuated, the towing device, which is held in its first or neutral position by two elastic rings, presses against a pressure sensor, whereby the booster additionally increases the braking force. Since the pressure sensor only controls the amplifier when the trailer is pushing the towing vehicle, the problems caused by pushing the trailer forward are not eliminated with this trailer brake either.
- the object of the invention is to ensure that the vehicle behavior is always flawless for vehicles from a towing vehicle with attached vehicles.
- the towing device when the towing vehicle brakes, the towing device is moved into a position pulled away from the attached vehicle, counter to the spring force which loads it.
- the trailer is thus kept on the train as a function of the actual deceleration, regardless of the braking pressure force of the towing vehicle.
- the trailer is cushioned against the towing vehicle, in particular avoiding empty swinging, and, on the other hand, dosed stretch braking of the trailer is achieved, even if the towing vehicle brakes minimally or maximally.
- the brake pressure regulator is opened and the brake pressure is thereby reduced until the towing device again reaches the second position. This regulates itself the braking force of the trailer independently via the spring-loaded towing device and the brake pressure regulator.
- the actuator which controls the brake pressure regulator, is actuated by an electrical transmission device between the towing vehicle and the attached vehicle, which is activated when the towing vehicle brakes.
- the electrical transmission device for controlling the actuator can be an electrical line between the towing vehicle and the attached vehicle, or a transmitter on the towing vehicle and a receiver on the attached vehicle for wireless transmission.
- the electrical transmission device is formed by this cable.
- the trailer braking system can be controlled by compressed air or hydraulic pressure, electromagnetically or mechanically.
- the brake pressure regulator can be operated mechanically.
- it can be designed as a control valve which is rigidly connected to the trailer device and is actuated by a linkage by the actuator.
- a control valve with an electromechanical drive can be used as a brake pressure regulator.
- the acceleration of the trailer device relative to the trailer can be detected with an acceleration sensor, and the distance by which the trailer device moves can be determined with an integrator.
- the actuator can be formed by a circuit which is controlled by the electrical transmission device and outputs corresponding control signals to the electromechanical drive of the control valve.
- a brake for attached vehicles namely when the braking pressure builds up when the towing vehicle brakes during forward travel (FIG. 1), when the braking pressure decreases when the towing vehicle brakes forward (FIG. 2), when driving forward without braking the towing vehicle (FIG. 3), when driving backwards without braking the towing vehicle (FIG. 4) and when reversing with braking of the towing vehicle (FIG. 5); and

- the cable 35 is connected to the brake light or the brake light relay circuit 37 via an electrical line 38.
- the actuator 13 is thus actuated when the brake of the towing vehicle 4 is actuated and the brake light 37 of the trailer 1 is thus switched on.
- the changeover valve 19 is between a forward travel position according to FIGS. 1 to 3 and a reverse travel position according to FIGS. 4 and 5 switchable. While it connects the line 18 to the main pressure line 21 and the pressure line 22 to the outlet 23 in the forward drive position when the brake of the towing vehicle 4 is actuated, it connects the pressure line 22 to the main pressure line 21 and the pressure line 18 to the outlet in the reverse position 23.
- the changeover valve 19 is controlled via the electrical line 39 of the cable 35, which is also connected to the brake light relay circuit 37 and is connected to the reversing light (not shown) of the trailer 1. If, for example, a 7-pin connector is used instead of a cable 35, for example a 13-pin connector 36, which is also designed for the trailer backlight, as shown in FIGS. 3 and 5, a device 41 for measuring the direction of rotation of the wheels 42 of the trailer 1 can be provided, which can be combined with a wheel movement measurement.
- the pressure cylinder 20 When driving backwards, the pressure cylinder 20 is separated from the main pressure line 21 by the valve 24 when the brake of the towing vehicle 4 is actuated.

- the compressed air tank 26 is connected to a compressor 43 arranged on the trailer 1, which is supplied with current by the cable 35 via the electrical line 44.
- the brake cylinder 12 can be pressurized via a further line 45, which is connected to the main pressure line 21 or the pressure vessel 26 via two safety valves 46, 47.
- the safety valve 46 is opened and thus the brake cylinder 12 is actuated when it is determined by the control unit 48 connected to the electrical line 38 of the cable 35 that the electrical transmission device for actuating the actuator 13 and the changeover valve 19 is defective when the plug 36 is inserted, and
- the safety cylinder 47 actuates the brake cylinder 12 when the pressure in the pressure vessel 26 is below a predetermined value.
- the safety valve 46 When the trailer 1 is put into operation, the safety valve 46 must first close, which is done by the control unit 48 when the electrical supply is established by permanent plus, ignition plus, for the brake light 11 and the reversing light or the switch 51.
- the pressure supply to the brake cylinder 12, the pressure cylinder 20 and the shock absorber 33 is regulated via the automatic load-dependent brake force regulator 32 in order to always ensure the optimum supply pressure which is matched to the respective loading of the trailer 1.
- a brake release device 55 enables the trailer 1 to move in the uncoupled state, for example in order to align it, move it or repair it in a workshop.
- the brake release device 55 can be actuated when the electrical supply to the trailer 1 is interrupted by loosening the plug connection 36.
- the brake release device 55 has a crank 56 on a threaded rod 57 m with a thread 58. It is connected to a pulling means 59 with a lever 61 which engages the brake cylinder 12. With the crank 56, the brake of the trailer 1 is released, so that it can be moved freely.
- the trailer brake is triggered when the service brake of the towing vehicle 1 is actuated.
- the brake light relay circuit 37 is actuated by actuating the brake pedal of the towing vehicle 4 via the cable 35 or the electrical line 38 and is thus connected to the main pressure line 21 by the valve 24 of the pressure cylinder 20.
- the piston 66 of the pressure cylinder 20 moves, as a result of which the linkage 28, 29, 30 moves the brake pressure regulator 9 into the position shown in FIG. 1, in which the brake pressure regulator 9 connects the main pressure line 21 via line 18 to line 11, as a result of which the brake cylinder 12 is actuated and the trailer 1 is braked.
- the pressure acting on the brake cylinder 12 and thus the brake pressure increases until the trailer 1 exerts a predetermined tractive force on the towing vehicle 4.

As a result, the pressure in line 11 is reduced and thus the optimum brake pressure is set again by the brake cylinder 12.
- the trailer device 2 In order to prevent the trailer device 2 from swinging back and forth, it is firmly connected to the structure of the trailer 1 via the shock absorber 33.
- the shock absorber 33 is designed so that the heavier the load, the harder it is regulated.
- the hardness of the shock absorber 33 can be adjusted by a compressed air / liquid-controlled axle suspension 68. This function is controlled via the automatic load-dependent brake force regulator 32.
- the valve 24 connects the pressure cylinder 20 to the outlet 69, so that the compressed air can escape from the pressure cylinder 20 (FIG. 3).
- the linkage 28, 29, 30 is moved so that the brake pressure regulator 9 connects the line 11 via the line 22 to the outlet 23 to reduce the brake pressure. Since there is no longer any tractive force acting on the towing vehicle 4 from the trailer 1, the towing device 2 is pulled back into the starting position I via the springs 6, 7.
- the brake according to the invention acts as an overrun brake. That is, the towing device 4 is moved by the trailer 1 pushing against the towing vehicle 4 into a third position, not shown, in which the towing device 2 is displaced towards the trailer 1 by compression of the spring 7 and pulling apart of the spring 6.
- the brake pressure regulator 9 according to FIG. 1, connects the line 18 connected to the main pressure line 21 to the line 11 to the brake cylinder 12.
- the overrun brake described in this way also acts when the engine braking effect of the towing vehicle 4 is used.
- the trailer brakes 1 is a full, because no current flows to the safety valve 46, whereby the safety valve 46 connects the line to the outlet of the 71st Since the brake cylinder 12 is actuated in the case of a pressure drop in the line 45, the trailer 1 is braked in the absence of current flow to the safety valve 46.
- the pressure cylinder 20 is connected via the valve 24 to the outlet 69 and thus, according to FIG. 5, the pressure line 11 to the brake cylinder 12 via the brake pressure regulator 9 and the line 22 to the main pressure line 21.
- the trailer 1 is braked so strongly that a slight pressure builds up between the trailer 1 and towing vehicle 4.
- the valves 19 and 24 are moved again to their starting position.
- the cable 35 with the plug 36 has fewer, for example only seven, poles, according to FIGS. 3 and 5 with the switch 51 and the wheel movement measuring device 41, for example a type of dynamo, which detects the movement and the direction of movement of the trailer 1 and thus the trailer brake in reverse operation, as described above.
- the embodiment of Fig. 6 is intended in particular for shoot ⁇ nenbone vehicles.
- the trailer or wagon 1 is provided at both ends with a control device 74 with a trailer device 2, which has a coupling 73.
- the control device 74 according to FIG. 6 is constructed in the same way as in the embodiment according to FIGS. 1 to 5, thus include the brake pressure regulator 9, the actuator 13 with the linkage 28, 29, 30, the shock absorber 33, and the pressure lines 11, 18, 22, 25 and 34.
- a graphic representation and description can therefore be dispensed with .
- the switching valve 19 is missing in the embodiment according to FIG. 6.
- the brake of the wheel 76 of the trailer is pressurized with compressed air.
- a main pressure line 78 leads from the hatched traction vehicle 4, ie the locomotive, from one end to the other end of the wagon 1 or the train.
- the main pressure line 78 is connected via a line 79 to a valve 82 with the pressure vessel 26.
- the valve 82 is closed.
- the pressure vessel 26 is connected to the actuator 13 or pressure cylinder 20 of the control devices 74 via the pressure line 79 and via electrical valves 83, 84.
- the electrical transmission device for controlling the actuator of the control devices 74 has a transmitter 85 on the locomotive 4 and a receiver 86 on the trailer 1.
- a controlled electrical control unit 87 which actuates the check valves 88, 89, which are provided in the pressure line 78 of the trailer 1, and also the valves 83, 84 between the pressure vessel 26 and the actuators of the control devices 74.
- the electrical control unit 87 is powered by the battery 91, which is charged by the wheel generator 92.
- the locomotive 4 and each trailer 1 are preferably provided on both sides with a transmitter 85 or receiver 86.
- the wagons 1 can also have transmitters which forward the control signal from the locomotive 4 to the rear.
- the control signal is a wireless electromagnetic signal, for example a radio or infrared signal.
- the coding of the locomotive transmitter 85 is stored so that the control unit 87 cannot be operated by external transmitters. If part of the train is disconnected, the coding can be canceled by a switch. When the locomotive 4 is uncoupled, a coded control signal can be sent, which cancels the coding of the wagons 1.
- the transmitter 85 of the locomotive 4 sends out a coded brake signal which is processed by the receivers 86 of the wagons 1. If the coding of the brake signal agrees with the stored coding, the valve 83 on the side of the locator 4 facing the locomotive 4 is trailer 1 open.
- the control device 74 now works exactly as described above in connection with FIGS. 1 to 5 ⁇ be enrolled.
- the shut-off valve 88 facing the locomotive 4 is closed in order not to forward the pressure drop in the main pressure line 78 to the locomotive 4.
- a wagon 1 designed according to the invention can thus also be used in one train together with conventional wagons.
- the main pressure line 78 running along the train has different functions. On the one hand, it serves to fill the pressure vessel 26, on the other hand, however, it forms a control line, in that the brakes of the wagons 1 are actuated in conventional wagons when the pressure in the line 78 drops. It is thus possible to brake all subsequent wagons earlier, even if they are not designed like the wagon 1 according to the invention. Even if, for example, only one wagon 1 according to the invention is present in the middle of a long train, the braking control of the following wagons takes place via this, with the result that the following wagons achieve a much faster response time and thus the braking distance is significantly shortened.
- the electrical control unit 87 can be used for any monitoring and storage functions. If the receiver 86 on the wagon 1 is simultaneously designed as a transmitter and the transmitter 85 on the locomotive 4 is also designed as a receiver, the data obtained can be transmitted via the transmitter of the wagon 1 to the receiver on the locomotive 1, stored there and by the locomotive control unit 93 are processed. For example, in order to prevent serious accidents, the rotation of the wheels of the wagons 1 can be checked in order to be able to quickly ascertain uneven running in normal driving operation. As The wheel generator 92 can be used for this purpose, for example. An overheating of individual wheels of the wagons can be reported by heat sensors 94 on the wheels.
- targeted stretch braking of individual wagons 1 can be carried out.
- Targeted emergency decoupling can also be carried out.
- the control units 87 and 93 are also data memories, all measurement and control data can be called up in a time-traceable manner.
