Description

State of the art:

Utility vehicles which have an additional output in the form of a profiled shaft for ancillaries such as for driving winches mowers, etc. are also used for landscape and forest care.

Commercial vehicles are for the purposes of this invention vehicles that not only allow for the transport of people, but can additionally operate equipment that can be used for communal purposes or landscape care purposes. Utility vehicles are Doka vans, trucks and tractors or construction machinery.

These profiled shaft connections are referred to as PTOs and are today driven by the internal combustion engine. They are switched on and off from the power take-off of the transmission by a switchable clutch.

Emergency power generators can also be connected to this power take-off, for example. Utility vehicle drives have an internal combustion engine that does not exceed a speed of 3000 U / pm in nominal operation.

Advantageously, economical diesel engines are used.

Diesel engines have a starter to start the engine and an alternator to charge the car battery.

PTO outputs are reduced by the crankshaft speed with i <5. The PTO speed is in the standard between 540 U / pm or 1000 / rpm, additional external generators can be connected to such a PTO connection with a vehicle-external PTO shaft, as well as mowers or wood shredders or garden shredders, etc. a more versatile link to the drivetrain is not given

The task is:

To design a versatile PTO with the main drive of the commercial vehicle also perceive more meaningful tasks and the Bertriebsicherheit the wheel drive can be increased if possible.

Solution:

The object is solved by the arrangement shown in the claims and the matching operating method of the associated claims.

The electric power take-off uses a one-piece, possibly screwed together housing which makes it possible to transmit high PTO shaft torques. By using a three-phase three-phase system with 120 ° phase shift, it is also possible to ensure the high power requirement of such PTO drives at even low phase currents. Safety devices for operating the permanently mounted in the vehicle alternator are advantageously installed

In combination with a front power lift module can be a unit with additional recording of the electrically powered by the electric pto accessories form.

Advantageously, the attachment of the electric PTO shaft by means of a flange on the same frame cross member between the lower links with the lifting cylinders and below the upper link connection

Operating methods which are carried out in combination with other vehicle measurements and with the bebienbarer switch complete the use of the module in a commercial vehicle with many advantages.

Mechanical features of the system are:

The increased mass moment of inertia through the electric motor 78 and gear 37 has a Zapfellendämpfende effect of the PTO 34 ,

The translated electric motor 78 enabled by its rotor inertia - and the gear circulation mass 37 Increased Smoothness of the E-PTO A common vehicle advantage is that the starter and alternator functions of the vehicle 1 in the PTO module 36 are integrated. The construction costs as well as the weight of the E-PTO 36 is compensated and many additional functions are possible, the vehicle 1 has a wider range of use

By using the three-phase use and supply as well as the three-phase output 175 . 176 on a three-phase socket and the rotary current fuse as well as a fault current protection 133 especially for commercial vehicles 1 (Truck tractors construction vehicles equipment carrier, craftsman vehicles) the increased power requirement result.

The with the machine judge 122 electrically connected three-phase input socket 175 can also the function of the three-phase output box 176 meet if a cable adapter (male / female Connection). The at the commercial vehicle 1 built-in plug is then always a safety reasons for a female to not come in Generatorbetrieb a bestomten hevorstehende connector pin and thus to induce an accident.

A multiplex operation of the E-PTO module 36 allows temporary powering of the PTO 34 also by the internal combustion engine 4 if the battery 189 or the battery 199 has loaded little energy by automatically closing the module coupling 70 with which the electric motor 78 from the control unit and the machine judge 122 immediately as a generator 78 is switched to Nebenbei the ACCU 198 or the battery 199 charge. The electric motor control unit requires an electrical pulse from the EEC 5 (or EDC 5 ) additional fuel quantities with adapted engine control 5 ,

PTO jacks (eg when chipping wood) is avoided by a power take off of the PTO shaft to the engine torque clutch 70 is closed and machine judge 133 is energized accordingly.

Electric PTO module in 36 Flange mount allows for symmetrical vehicle mounting in combination with front hydraulics 167 . 168 . 158 between the two lower links of the three-point receiver with: two lower links 167 and associated lifting cylinder 158 ; top link 166 and module flange with E-PTO module 36 practical pre-assembly possible.

By joint mounting on the crossbeam 15 made of steel or cast iron of the commercial vehicle 1 is favorable power flow of the torque arm 171 and the reaction forces possible by introducing into the vehicle frame 14 Component savings by using common fastenings of the front hydraulic articulation points 168 with the electric power take-off module 36 is possible

Particularly due to changing directions of rotation (right-hand left-hand rotation of the power take-off shaft) and infinitely variable adjusted speed change is the combination of the electric power take-off module 36 in combination with a front hydraulics when using the same load-bearing fastening crossbeam 15 good - The torque arm 16 for changing torque is in the front hydraulic assembly 15 integrated.

Direct traction through the same frame carrier 14 from the field rail 189

With the common framework 14 it is possible that resulting from a tensile force boosting force which is induced by the torque at the E motor in the same frame 14 Compensate depending on the gear engaged by the Zugraftboosting (= traction support of the commercial vehicle 1 ) briefly up to 40% of the total traction of the commercial vehicle or tractor or implement carrier so up to 4 tons. The gear 37 allows these torques with acceptable size of the module 36 ,

Automatic sporadic traction support time-critical traction support possible due to very fast response time of the E. engine t <0.2 sec. An electrical connection to the traction force sensor of the track rail allows the traction power control to retrieve power from the electric motor. The electric PTO checks the battery level and closes the clutch first 70 To connect to traction until briefly up to 300 Nm torque, for example when plowing until the hard or deep bump is over.

The engine control unit 5 can also without tension sensor 188 the electric motor control unit 115 communicate via an electrical impulse that instead of a gear in the manual transmission 21 switch back the electric motor after previously closed clutch 70 Torque to the crankshaft 6 should give. This greatly reduces the switching frequency and protects the gearbox 21 and the transmission clutch 22 with the clutch disc 24

Thereafter, by a kind of multiplex operation in which the ACCU temporarily by the combustion engine 4 powered electric motor 78 be powered as a generator and so the battery 198 , 199 be recharged during plowing, for example, by the EEC-EDC 5 to the electronic request of the E-engine control unit 5 an extra power on the crankshaft 6 to charge the battery so that without driver influence the battery during the work of the utility vehicle 1 is loaded again. Typically, more fuel is injected sequentially and air is supplied with adjusted engine status.

The battery 198 can also be powered by multiple batteries 199 be replaced. The supply voltage of the machine judge 122 from the battery should not fall below 48 V and is ideally between 80 V and 180 V.

By the driver conditional traction support of the electric motor 78 With a kickdown of the gas pedal 159 , a quick and deep operation of the accelerator pedal 159 this function is mainly initiated. Kick down function, with strong fast accelerator pedal pushing spontaneous additional accelerator pedal travel. It becomes the module coupling 70 closed first and the electric motor 78 gives up to 25 KW of the engine crankshaft 6 from around the internal combustion engine 4 To prevent stalling without having to switch back, very comfortable operation of the vehicle 1 , Speed of crankshaft 6 is then kept constant according to the accelerator pedal position, no stalling of the internal combustion engine 4 , A typical situation is, for example, the extraction of a heavy beet trailer from a wet furrow in the higher road.

Functions with closed clutch 70 and active electric PTO

Internal combustion engine idle controller and with back damper prevents stalling of the internal combustion engine 6 even with Untertertigem operation of the internal combustion engine as a result of uneven load or error, for example, clogged fuel nozzles of the engine 4 The electric PTO 46 can by means of electric synchronization process, when accelerating the shaft 40 on coupling speed of the shaft 17 be switched on and off automatically and without slip. Advantageously, a synchronous switching device 53 used for this switching process. This synchonization of the two waves to be coupled but also in the wet here used oil-lubricated multi-plate clutches 70 used to keep the shift slip small and the clutch 70 to protect

Crankshaft jerk damper and stabilized stall gas by torque output of the electric motor 78 in the module to the internal combustion engine crankshaft if this runs out of bounds (a so-called idle-boosting) starter and generator function as today according to the prior art, but taking into account the battery capacity and allowable battery / battery charge.

The Rekuperationsfunktion means in the case of the retarder is activated by retarder is depending on the switched-on retarder level of the battery charging current from the machine judge 133 set to provide appropriate additional braking power for the vehicle.

The stabilizing gas function means in the case of a donor or lever 214 set hand throttle does not reach the required achievable tractive force of the vehicle is automatically the electric motor 78 supportive without any gearbox intervention 21 is required by a switch back.

Especially for commercial vehicles with manual transmission 21 This mode of operation protects the clutch 22 . 24 the drive train as less needs to be coupled. In addition, there is no traction interruption. This allows uninterrupted pulling of a trailer or a plow of Nutzfahtzeugs 1 at occurring bumps.

The transmission control unit 205 preferably has an electrical line connection for the exchange of measured values and operating data to an internal combustion engine control unit EEC-EDC 5 and to electric motor scaler 115 ,

So it is possible that the internal combustion engine 4 additional torque from the electric motor 36 with the clutch closed 70 Requires in the case of this with the required by the vehicle or the driver driving a gear back would have to switch back. Thus, the clutch 22 be spared because fewer switching cycles must be performed. When pushing the accelerator pedal 159 we the clutch 70 closed and the electric motor 78 gives off one of the batteries 199 . 198 supplies a so-called boost torque. while supporting the electric motor 78 briefly until the pedal travel of the gas pedal 159 is taken back with its torque.

The translated electric motor torque is about 25% of the engine torque, this shows that this size also has a vehicle-friendly effect, the downshift is not required

A tensile force sensor 198 a farm rail 189 To which, for example, a plow is attached, can by its electrical connection to the electric motor control unit 115 Also request additional torque by previously the clutch 70 is closed or the generator operation is interrupted briefly and until the tensile force sensor required traction back from the engine 4 is covered without switching back. Another additional advantageous feature is a so-called Anfahrladerfunktion miitels an additional loader 12 , By driving an additional compressor 12 by means of the shaft 40 with the clutch open 40 It is possible for a short time an additional compressor for charging the internal combustion engine 4 via further translating drive means 183 drive very fast. As a result, additional oxygen can be pushed into the combustion chamber during an under-revving process, whereby a boosting effect of the boost occurs which, in addition, prevents the generation of soot during start-up. It is advantageous for this function if the waste gate bypass 13 ' at the turbocharger turbine of the standard turbocharger 13 '' is closed before and during the boosting process by the additional compressor 12 remains closed. In low-speed driving brings the standard turbocharger according to the prior art due to the small amount of exhaust little air pressure in the combustion chamber.

The 1 shows a steering cylinder 89 that of a valve 91 is controlled, this valve 91 advantageously by a hydraulic power steering pump 104 (Comp. 4 ) is supplied with oil.

The PTO shaft 34 allows driving various attachable attachments (broom mower mower etc, etc) by the electric motor 36 powered PTO 36

With the clutch open 70 The drive of the accessories can be independent of the engine status and its speed.

With the clutch closed 70 is a torque-assisting drive the PTO as needed in coordination with the engine control unit possible, wherein the electric motor with the aid of the speed sensor or a rotation angle sensor 119 at the PTO 34 can perceive a vibration damping function.

At noticeable declining speed at the pto, the electric motor gives 78 Torque decreases and as the PTO speed increases above the preset value due to the hand throttle on the commercial vehicle 1 will this PTO 34 braked by the electric motor 36 briefly works as a generator.

Use of the electric motor 78 in GPS control unit in commercial vehicle 1 allows a linkage of the PTO speed 34 also in uncoupled condition By coupling 70 with a timestamp.

This makes it possible to write a log, which, for example, the current salt or düngerstreumenge refers to the driven way or the processed parcel. For input Can be programmed by an operating device, the speed-dependent spreading quantity.

Through the individual PTO speed 34 the independent of the engine speed of the crankshaft 6 It can be realized that the PTO speed is independent of the driving behavior of the commercial vehicle 1 a constant accurate application, for example, of fertilizer or the seeding allows without a complex additional electronics in the attachment or additional device to require.

Advantageously, the electric motor also performs Drehwingungsdämfungen by the clutch is closed 40 around the crankshaft 6 Vibration damping to be able. For both vibration damping functions, it is advantageous to have a transmission 37 with the largest possible fixed translation to the common module shaft 40 to have interposed to have an electric motor rotor translation to be damped shaft, thus the rotor can also at high shaft speed of the shaft 17 and or 40 react very sensitively and reduce the vibrations. Advantageously, a speed sensor measures 119 the electric motor speed with which it is possible that the transmission improves the resolution of the speed sensor with respect to the common module shaft according to the translation. Advantageously, the transmission gear is a gear transmission with little backlash that is lubricated with lubricating oil. Advantageously, the power take-off shaft is mounted with rolling bearings which are advantageously lubricated oil to operate sustainable and trouble-free even at low speeds of the common drive shaft sufficient payloads and torques.

Description of FIG. 3

3 shows an attachment 102 and the front hydraulic system 203 with the module 36 preassembled.

The lower links 167 which each of a hydraulic lifting cylinder 158 can be adjusted in height hold the attachment 102 (shown here as a shredder) and a power take off or profilwellenmuffe can the accessory of the PTO 34 through the electric motor 34 over the transmission 37 are driven.

The supply of the lifting cylinder with hydraulic oil can be done by the oil pump 20 be realized, which is possible with the clutch open 70 and stationary combustion engine 4 powered from a three-phase socket to drive such an accessory even with high power requirements, for example, about 3 KW.

On a common frame crossbar 15 the module and the lower links are attached to the hydraulic cylinders

This frame crossbar 15 is with the vehicle frame 14 connected or bolted. The module 36 the front PTO has a flange 171 which is capable of torque in the crossbeam 15 initiate without a twisting of the module relative to the front hydraulics is possible.

The front hydraulic module can also be mounted in the rear of a commercial vehicle or equipment carrier.

The front hydraulic module consisting of> module 34 cylinder 158 and lower link 167 Lower link attachment 168 can be at least partially pre-assembled and tested before it on the vehicle frame 14 by means of the frame crossbar 15 is attached.

Advantageously, the frame cross member 15 between the lower link recordings 168 welded or screwed, in the case, it is advantageously completely pre-assembled and can after pre-assembly including the module 36 with the frame 14 get connected. In the latter case, it is advantageous that this module can also be optionally replenished and installed in external workshops in the vehicle and last version is more precise testable and robust as this then torsion-resistant unit by the final assembly on the flag also due to the frame tolerances of the vehicle frame 214 can not be distorted and thus damage the module 36 is also missing, it is possible that the hydraulic piping of the lifting cylinder 158 and the associated valve as well as the hydraulic pump piping of the pump 20 is possible.

Description of FIG. 4

4 shows the electric PTO module 36 with the electric motor 78 which is preferably constructed as a water-cooled permanently excited synchronous motor.

The oil bath and oil circulation oil lubricated transmission 37 with at least one lubricating oil connection 201 , The electric motor cable 221 connects the electric motor windings with the power unit 117 in which at least the machine judge 122 is housed.

An electrical cable 107 connects the electric power unit 117 with the electric motor control unit 115 ,

The mounting flange 171 enables torque input into the crosshead 15 which with the lower link recordings 168 and the Hubzylinderaufnahmen 168 forms a structural unit.

Optionally, the module can 36 a compressed air compressor 103 be installed or screwed. Other additional consumers such as a hydraulic pump 20 , an oil power steering pump 104 , or an air conditioning compressor 105 can by the electric motor 78 from a three-phase socket 175 be powered powered.

A switchable clutch 207 preferably a dog clutch allows the PTO to turn off 34 for example, when plugging a Zusatzverbrauchers 102 even with the clutch closed 70 to the wave 17 which with the crankshaft of the internal combustion engine 4 rotatably connected.

The switchable clutch 70 is designed so that it is automatically closed even at a system error to at least the starter and alternator function for the commercial vehicle 1 through the electric motor 78 sure. Advantageously, this coupling 70 then directly or indirectly by a force of the spring 60 switched to an emergency position. This spring 60 Can be as shown directly on the clutch 70 which is designed here as a multi-plate clutch be installed or due feather 60 is at the switching valve 71 fixed Advantageously, the solenoid valve 71 then constructed such that this solenoid valve 71 the coupling 70 automatically closes when the valve is switched off. Advantageously, as a pressure means for actuating the clutch 70 Hydraulic oil or compressed air from an accumulator tank 66 taken from the switching of the clutch 70 even when the vehicle is still to be secured.

A temperature sensor 83 measures the temperature of the electric motor 78 in the field of field windings of the stator and a speed sensor 119 measures the electric motor speed. Both measured values are the electric motor control unit 115 for comparison with the stored permissible values in the electrical random access memory of the control unit 115 transmitted electrically.

In position B (Pos B) is as a transmission gear 37 an embodiment as a bevel gear which advantageously also runs in an oil bath in the module housing 45 built-in. Advantageously, the bevel gear pinion is offset by a smooth run of the module shaft 40 To ensure that a helical or hypoid gear teeth, for example, a Hirth bevel gear is installed. Such bevel gear teeth run very quiet and quiet. Advantageously, this transmission version is lubricated in the oil bath by immersing the gears and the oil on the rolling bearings of the shaft 40 to distribute. The oil level h is measured with an oil status sensor (a sensor that measures the oil level and / or oil pressure).

Without a sufficient oil level in the immersion bath with the required depth, h 'related to the oil return port and or the oil pressure of a connected oil circulation lubrication driven by an oil pump, the module is only for emergency functions from the control unit 115 released for example for the realization of the starter function and the alternator function for the commercial vehicle. An electrical optical error signal indicates to the driver this malfunction.

The Pos CZ the 5 shows the clutch 70 as a switchable multi-plate clutch here being the spring 60 directly in the clutch 70 is installed.

In case of power failure at the valve 71 closes the clutch 70 , this ensures that the electric motor 78 even after a long parked commercial vehicle 1 again the internal combustion engine 4 can start, even if the compressed air tank 66 and or the oil pressure vessel, which is preferably designed as a diaphragm pressure accumulator, are empty.

Description of FIG. 5

5 shows the clutch 70 as a synchronous clutch, wherein the shift sleeve 63 by an electromagnetic encoder, for example, an electric motor 54 or an electromagnetic magnetic switch 54 can be operated.

The diagram switching operation module synchronous coupling also applies to the use of a switchable coupling 70 shown as a multi-plate clutch after the 4 ,

Here, first, the driven auxiliary consumers 103 105 . 20 , or the PTO 34 contagious additional consumers 102 in its power consumption by means of solenoid valves 98 or electrically switchable couplings 99 reduces as far as the driving of the commercial vehicle 1 allows.

The electric motor 78 then accelerates the module shaft 40 to the synchronous speed of the shaft 17 that of the internal combustion engine 4 is driven. This speed of the module shaft is measured 40 from the speed sensor 119 in the module 36 ,

The electric motor control unit 115 compares this speed with the speed of the zuzuschaltenden shaft 17 which from the combustion engine 4 is driven. If almost the same speed of the shafts is reached then the clutch 70 , shown here as a synchronous clutch closed.

When you open the synchronizer clutch of the secondary consumers by means of electromagnetic valves 98 as far as this in turn allows the operation of the commercial vehicle this allows or reduced in its power consumption and then the clutch 70 open.

Description of FIG. 6

6 shows the electric PTO module 78 with a chain transmission, preferably a lubricated in oil bath link chain.

The electric PTO module 36 for a commercial vehicle 1 , according to one of the claims above is characterized, inter alia, that for the translation of the electric motor speed 78 in the common housing 45 an oil-lubricated multiple chain drive is used wherein at least one chain tensioner 43 . 48 both of them when operating the module 36 alternating tension cords by means of chain tensioner 43 . 48 be tense. The chain is preferably designed as a douplex or triplex chain (two or three-row chain guide), advantageously this chain is then redundant and particularly robust. Such multi-membered double or Triple chains are robust, especially if the roller or sleeve is mounted in plastic bushings which is engaged with the teeth of the sprocket run such chain drives very quietly.

Preferably, a sleeve chain is used which runs very quietly. Preferably, the chain runs in the oil bath and or is oil spray lubricated. Preferably, both tension cords are by chain tensioners 43 . 48 curious because the direction of rotation in PTO mode and the torque its sign by the hybrid application of the module 36 can change constantly.

Advantageously, this is the sprocket 52 that with the PTO 34 connected and the sprocket 51 of the electric motor 78 in the common housing 45 stored. Preferably in rolling bearings. Another sprocket 49 a secondary consumer 20 . 105 for example, an air conditioning compressor or a hydraulic pump 20 can with the chain 42 are driven. The chain tension wheels 43 and or the tension rails 48 are preferably by a tension spring 46 preloaded in order to be able to tension the chain without the hydraulic pressure during electric operation of the PTO shaft from the three-phase socket.

A tensioning of the clamping elements 43 or 48 by means of a hydraulic cylinder is also advantageous or conceivable.

For particularly high loads, it is advantageous to use a toothed chain which is advantageously also oil-lubricated. A grease-lubricated chain is due to the high duty cycle of the electric motor 78 by the starter, alternators and generator function as well as to drive from the PTO and other auxiliary consumers in the state and when driving in this combination with the operational maintenance-intensive and therefore disadvantageous.

Description of FIG. 7

7 shows a diagram of the active damping of auxiliary drive units which by means of the module 36 built-in electric motor 78 can be driven.

The distorted sinusoid shows the torque M of a compressed air compressor which can be built into the module for generating compressed air. The speed and angle of rotation of the module shaft 40 gets me a sensor 119 measured in the module. The diagram shows a changing torque on the module shaft 40 due to the compression process of the air compressor 103 , The black area is the area of charge change in the air compressor 103 , In this area, the outlet valve opens because the delivery line pressure or the compressed air tank pressure in the container 66 smaller than the compression is, and the compressed air is expelled from the compressor room. Part of the compressed air remains due to the damage area in the compressor room back. This remaining part of the compressed air generates a negative torque during the following intake stroke.

The torque at the compressed air compressor crankshaft and thus the module shaft 40 changes very much within 180 °.

The active torsional vibration damping function of the electric motor 78 now allows the power of the machine judge 122 to the electric motor 78 can be withdrawn before reaching the top dead center. Thus, the rest of the compression process in the period tp with the kinetic energy of the reduced mass of the crank mechanism and its speed can be completed and the current for the electric motor 78 is only increased again when the rotational angular frequency of the air compressor 103 has fallen below a minimum rotational angular frequency.

This makes it possible that a mean reduced uniform current in the electrical system, consisting of the electric motor windings and the machine judge 122 and then the drive of the air compressor 103 very quiet and quiet.

The advantage is the current reduction by the period tp1 before reaching the maximum compressor pressure 103 is reduced. This function of active torsional vibration damping on the module shaft 70 advantageously based on a PID control process runs in the background without the driver can exert massive influence on it and is only possible by the intelligent electrical behavior of the module 36 with the control units 115 117 is in particular when using a permanent-magnet synchronous motor 78 helpful because its fast time constants have a positive effect. The driver of the commercial vehicle notices only the quieter running than for example in a hydrostatic incompressible and torsionally rigid drive system. All drive elements 37 . 40 . 34 and joints are spared. The function can be done with the clutch open 70 and with the clutch closed 70 be performed.

The oil cooler of a state of the art hydraulically driven PTO 34 deleted as well, since advantageously in an electrically driven front PTO 34 the waste heat via a cooling water connection 39 directly to the Cooling water circuit of the internal combustion engine 4 can be delivered.

Pos B in 7 shows a data input device and smart card storage unit with a reading device and a data carrier in which data of the front PTO operation can be stored

With the data input device 209 can the front pelves 34 are influenced in their speed and direction of rotation.

The front PTO can be turned on and off, and an automatic speed calculation of the PTO 34 according to the specifications of the maximum spread of an additional device 102 and maximum allowable application rate can be realized with it.

An advantage of the electric front PTO 34 is that electric motors control unit 115 the speed of the PTO 34 according to the specifications of a constant area performance to fertilize or scatter with the clutch open 70 can adjust regardless of the condition of the vehicle drive.

The actual speeds given off by the electric motor are provided with a time stamp and can be sent by the electric motor control unit to a USB memory card reader for storage. The USB reader is connected to the electric motor control unit with an electric cable and also installed in the cab.

Advantageously, this smart card reader can 209 in the electric motor control unit 115 to be built in.

This allows an evaluation of the data on the PC at home to document a log of the fertilizer allocation on a field and to be able to observe and optimize the area growth.

The data reader 209 has a connection to a GPS and or a vehicle speed sensor, for example, to the ABS or the tachograph of the Nutzfahrzeugt. Advantageously, if the data storage device 209 a potentiometer 211 or a keyboard 211 has to the electric motor control unit 115 to communicate the desired application rate and at least one accessory specific parameter z B the spread width per driven speed speed of the PTO 34 which of the accessory drive number 102 of the attachment z B corresponds to the spreader As well as that of the attachment 102 amount of fertilizer delivered per revolution of the PTO shaft 34

Will this module 36 For example, in a gear tray which can drive up to 80 km / h and can be used in winter service mounted their standard standard PTO front mounted on the commercial vehicle so may have the additional pto described here 34 with the module 36 then be operated in the rear of the vehicle, so it can be a spreader to the salt shaker with the module 36 be driven and the data can be documented at the same time the starter and the alternator and further functions such as stationary air conditioning., three-phase alternator, PTO operation from the three-phase network serving width of use of the commercial vehicle 1 advantageously widened.

For permanent deliveries to the PTO shaft over 25 Kw, for example, when operating a heavy tiller is the clutch 70 closed and the electric motor 78 goes into the generator function or alternator function. The active vibration damping function of the PTO shaft 34 and the crankshaft 6 remains switched on when the battery level of the battery 198 or the batteries 199 this is allowed.

Description of FIG. 8

8th shows the electric motor controller 115 which with an electrical connection 107 with the active inverter interface 179 communicates and which at least the machine judge 122 that the electric motor 78 powered drives.

A network judge 123 allows three-phase mains operation also to deliver power to the three-phase socket 176 which advantageously by a multi-phase fuse 133 which also advantageously outputs a fault current monitoring RCD function. These measured values and data of the fault current measurement RL1, RL2, RL3, N, which are carried out by means of an ohmic or inductive current sensor on all phases L1, L2, L3 and the neutral conductor N go to the electric motor control unit 115 for processing too. If a fault current deviation occurs, the three-phase contactor 129 opened and the power to the inverter 123 . 122 interrupted. Advantageously, when pressing an emergency button in the front PTO module, the current through this three-phase contactor 129 To be interrupted in an emergency, for example, an impending occupational accident, the electric motor 78 to be able to switch off.

Shown is a to this outlet 176 attachable additional electric appliance 250 for example, a steam jet device.

In particular, when electrical accessories are operated in a humid environment a fault current monitoring is helpful.

An additional possibility for earthing the utility vehicle with a grounding anchor is also advantageous 146 which s.einer grounding socket or screw 144 this can be fastened allows a grounding of the commercial vehicle 1 there the tractor tires 92 or commercial vehicle tires 92 en three-phase generator 78 isolate, when working in damp areas, this is an advantage because the working engineer is not necessarily a Nulleiterkabel N Connected with the legs well grounded in the water can stand.
