Definitions
- the invention relates to a vehicle train with a vehicle driven by electric motors according to the preamble of patent claim 1.
- Manual transmission is coupled to a mechanical drive train, but which drives an electric generator.
- the drive wheels of these vehicles are driven by electric Aehs- or wheel motors, which draw their electrical current from the generator.
- Electric motors are controlled by an electronic control.
- the electric motors and the generator are designed as “multiple electronic permanent magnet machines” (MED machines). They have an internal stator part made up of a large number of stator laminations, which are arranged in a star shape and wound with individual coils.
- MED machines multiple electronic permanent magnet machines
- the rotor part which consists of a magnetically conductive ring with permanent magnets of the type rare earth cobalt or rare earth iron, is arranged around the stator part.
- the electronic frequency converter is provided by the single frequency converters
- Vehicle parts arranged, with the drive wheels in the
- Trailing axle is driven by an internal combustion engine via a conventional drive train with a manual transmission.
- an electrical or electrohydraulic drive for the central axis of the vehicle to be fed from a power supply is provided. Simultaneous operation of both drives is not considered.
- DE 37 25 620 A1 discloses a drive and brake concept for a motor vehicle with an internal combustion engine / generator unit for supplying the electric drive motors of its wheels, in which a traction control and an anti-lock control are provided. Trailer operation is not mentioned there.
- the object of the invention is to improve a vehicle train of the generic type in its driving properties, in particular with regard to its traction, without this requiring an excessive construction effort.
- Figure 1 is a side view of a vehicle train with biaxial
- Figure 3 shows a drive concept of an inventive
- Figure 1 is a schematically designed as a truck
- the trailer 2 is mechanically connected to a trailer coupling 13 of the towing vehicle 1 via a drawbar 14.
- v represented by an arrow
- F WG transmission resistance of the towing vehicle
- F WB acceleration resistance of the towing vehicle
- the force acting on the towing vehicle 1 as resistance tensile force F Z is in its absolute magnitude of the tensile force F z is equal to that exerted by the coupling 13 to the drawbar 14 of the trailer 2 and is directed in the direction of travel:
- the driving resistance forces marked by a line have the same meaning in relation to the trailer as the driving resistance forces of the towing vehicle explained above.
- the invention is distinguished from the known vehicle trains in particular in that not only the towing vehicle 1 but also the trailer 2 has driven wheels 5. Under certain operating conditions, it is particularly advantageous to drive all of the wheels 5, 6 of the trailer 2. This gives the vehicle train maximum traction.
- the wheels 5, 6 are driven by
- Lines 16 dosed accordingly supplied with electrical current.
- the optional electric motors 10 on the wheels 6 and the associated power lines 16 are shown in dashed lines in FIG.
- the dash-dotted lines 17 indicate that the electronic control 11 continuously the signals required for the control of the electric motors about the current operating state of each
- Electric motor 7, 8, 9, 10 receives.
- the two-axle trailer 2 has a steerable front axle (subframe steering) since the front axle, which is rigidly connected to the drawbar 14, can be pivoted about a pivot point.
- the trailer 2 can also be single-axis or other axes (e.g. rear
- the electronic control 11 supplies the electric motors 9 and optionally 10 with metered power in such a way that the trailer 2 exerts a tractive force on the towing vehicle 1 at all times, that is to say during the
- Forward driving mode does not change to push mode (e.g. when driving downhill).
- the power supply can possibly proceed in a negative direction, that is to say that the electric motors 9, 10 can also be used temporarily as generators to generate electricity, and thus generate a negative drive torque (braking torque).
- the monitoring of the magnitude of the tensile force on the drawbar 14 is ensured by a corresponding sensor (not shown) (e.g. strain gauge), which is connected to the electronic control 11 in terms of signal technology.
- a higher minimum tractive force value F Z is to be provided at a higher driving speed than at a lower speed.
- the vehicle train according to the invention has devices (for example sensors in the area of the wheel suspension or the steering of the steerable wheels 3 of the towing vehicle 1) for detecting the steering angle ⁇ of the right front wheel 3 or the steering angle ⁇ of the left front wheel or both steering angles ⁇ , ⁇ by the electronic Control 11.
- the electronic control 11 can record the current driving speed v of the vehicle train at any time. This can
- Another essential feature of the invention is that in the electronic control 11 in the form of stored table values or calculation algorithms a unique assignment of one of the
- Steering angle .alpha., .Beta. Or both steering angles .alpha., .Beta. Take place at a sol l steering angle of the trailer 2 or at a value representing this target steering angle.
- the steering angle ⁇ , ⁇ can be seen in FIG. 2 as the angle between the axes of rotation of the steered wheels 3 and the axes of rotation of the unguided wheels 4.
- the steering angle ⁇ of the trailer 2 is formed between the axes of rotation of the wheels 5 and 6 and is therefore equal to the angle between the drawbar 14 and the longitudinal axis of the trailer 2 (turntable angle).
- the angle between the drawbar i.e. the longitudinal axis of the trailer
- the longitudinal axis of the towing vehicle can be referred to as the steering angle of the trailer.
- r ⁇ curve radius, that means distance of the longitudinal axis of the
- unguided rear axle of the tractor l D effective drawbar length of the trailer, that is, horizontal distance of the axis of rotation of the steered trailer axle from the coupling axis of the
- the speed of the former must be set correspondingly higher.
- Circular drive i.e. clarify when turning the vehicle into a curve.
- Steering angle .alpha., .Beta. Is set to corresponding values which are detected by the electronic control 11 via steering angle sensors. From the current steering angle ⁇ or ß, as described above, a target value for the steering angle ⁇ of the trailer 2, i.e. in the
- Phase shift t ph follows the temporal function of the steering angle ⁇ is corrected by the electronic control 11 in the drive. This is preferably done in such a way that, on the one hand, the drive power on the wheels 5, 6 of the trailer 2 is reduced, and, on the other hand, by means of speed difference control of the wheels on the outside of the curve and on the inside of the curve, the actual steering angle ⁇ to the
- Target steering angle is approximated. Instead of the steering angle ⁇ des
- Towing vehicle 1 could of course also be used in a corresponding manner, the steering angle ß.
- appropriate sensors would have to be provided for detecting the lateral acceleration. Since the speeds and torques and thus also the drive power of the electric motors 7, 8, 9, 10 are monitored by the electronic control 11, traction control can be carried out in the vehicle train according to the invention without great effort. Inadmissibly high slip on individual driven wheels 3, 4, 5, 6 can easily be determined by comparing the wheel speeds with one another.
- each electric motor 7, 8, 9, 10 can be addressed individually by the electronic control 11 within fractions of a second, an immediate individual reduction of the drive power and thus the drive torque to values such as those on the respective wheel 3 is possible , 4, 5, 6 no more illegal slippage occurs. This results in the possibility of reducing the
- Cornerers Is recognized by the electronic control 11 (e.g. by comparing the steering angle of the towing vehicle 1 and the
- This increased slip can be easily recognized by the electronic control 11 by comparing the speed and / or torque values of the electric drive motors and causes the electronic one
- Control 11 not only for the already mentioned reduction of the corresponding drive torque but also for a metered redistribution of the drive forces to "uncritical"
- the electronic control system performs an evaluation of the values of the actual tractive force t F z on the drawbar 14 and / or the steering angle ⁇ of the trailer 2, which are recorded over time, for periodic fluctuations. This provides information about an impending threat
- the electrical current for supplying the electric motors 7, 8, 9, 10 can be taken from an accumulator, for example.
- the electrical current is preferably in a
- the drive concept according to the invention is also particularly advantageous for vehicle trains with a single-axle trailer, for example for articulated buses. It is completely irrelevant from the drive technology point of view whether the internal combustion engine / generator unit is accommodated in the trailer 2 or in the front end, since the energy transmission to the electric drive motors in a drive according to the invention
- Vehicle train can be done by electrical cables and plug connections in a simple and extremely flexible way.
- the dykes, el in the sense of the invention are physically fused directly to the floor of the rear car attached to the front car.
- the invention makes it possible for the first time that an articulated bus can drive through curves forwards and backwards in the same way. This is of great importance for a shunting operation, for example in congestion in city traffic.
