Definitions
- the invention relates to an engine dust brake device with an internal combustion engine Engine dust brake device and an engine brake flap in an exhaust pipe, with a servomotor for the engine brake flap and assigned power section, which receives its commands from a control unit, and with one the pressure pressure sensor in the exhaust line in terms of flow in front of the engine brake flap.
- the invention is based on DE 33 39 053 C2.
- An engine brake flap adjustable by means of a pneumatic actuator.
- a pressure sensor that the Exhaust gas pressure in the exhaust line is measured in terms of flow in front of the engine brake flap, is connected to a solenoid valve that when a certain pressure threshold is reached switches and thus a compressed air-controlled opening of the engine brake flap causes.
- the Servomotor and power section as well as the pressure sensor and / or temperature sensor a brake device module with an exhaust pipe section that functions as a carrier base, a compactness with the Possibility of a favorable arrangement close to the internal combustion engine.
- an exhaust pipe is designated 1, which is connected to an internal combustion engine, in particular a truck or bus.
- This internal combustion engine has its own engine brake device, e.g. B. that according to EP patent 0736672.
- 2 denotes an exhaust flap, which is installed in the exhaust pipe 1 and is rotatably or pivotally mounted there with its axis 3.
- 4 with a servomotor for the adjustment or adjustment of the engine brake flap 2 is designated.
- This can be implemented by an electric motor or a hydraulically or pneumatically actuated actuating cylinder.
- the servomotor 4 is realized by a pneumatically actuated actuating cylinder, which can be supplied with compressed air via a compressed air line 6 connected to a compressed air supply device 5.
- the servomotor 4 is assigned a power unit 7, which in the example shown consists of an electromagnetic shut-off / passage valve 7 'and an electrical switching element 7''for actuating the latter.
- This power unit 7 receives its commands from a control unit 8.
- 9 denotes a pressure sensor which detects the exhaust gas pressure in terms of flow in front of the engine brake flap 2.
- a temperature sensor 10 can be provided which detects the temperature of the exhaust gases in terms of flow in front of the engine brake flap 2.
- This consists, for example, of an input and output periphery, a microprocessor, data and program memories, which assemblies are linked together via a data bus system.
- Characteristic maps and operating data for the operational control of the internal combustion engine are stored in the data memory both in the traction mode and in the braking mode.
- the controller unit 13 thus controls the operation of the internal combustion engine as well as the operation of the control unit 8 by means of the characteristic diagrams and operating data in the program stored in the program memory. The latter during engine brake operation in the sense of a sensitive adjustment or adjustment of the engine brake flap 2 for the purpose of increasing the braking power .
- the controller unit 13 gives its commands via line 14 to the control unit 8.
- the latter in turn gives its commands via line 8 'to the switching element 7''. This in turn is connected to the shut-off / passage valve 7 'via switching lines 7a, 7b.
- FIGS. 2 and 3 An embodiment of the braking device module according to the invention is shown in FIGS. 2 and 3 evident.
- This in its entirety designated 15 brake device module has an exhaust pipe section 16 as the base element, the end flanges 17, 18 in a corresponding free space of the exhaust pipe 1 is installed.
- the engine brake flap is in this exhaust pipe section 16 2 installed and pivoted with their axis 3 outside are on this Exhaust pipe section 16 of the servomotor 4 for the engine brake flap 2, the associated power unit 7, in the example shown the electromagnetic passage / shut-off valve 7 'and switching element 7' ', the associated control unit 8 and the Pressure sensor 9 and / or temperature sensor 10 attached.
- the one in the present example is a servomotor 4 formed by a pneumatically actuated actuating cylinder articulated at one end supported on a bearing block 4a, acts on the other its adjusting piston 4 'on a fixedly connected to the axis 3 of the engine brake flap 2
- Control lever 3 'and is connected to the compressed air line 6 via a connection 4' '.
- a heat insulation layer 19 is corresponding Placed thickness, which serves the outer parts 7 ', 7' ', 8 of the brake device module protect against overheating.
- the brake device module 15 is completely preassembled with all of its parts then installed in the free space of the exhaust pipe 1. There are each other facing ends provided flanges, their mechanical connection with those flanges 17, 18 of the brake device module 15 via corresponding ones Fittings are made. For this, screw through holes are 20 in the flanges 18, 19 available.
