Definitions

  • the invention relates to a drive system for a vehicle according to the preamble of claim 1.
  • Electric machines are increasingly used today to drive vehicles, especially commercial vehicles, in road traffic (see “An electric single-wheel drive for city buses of the future" by B. Wüst, R. Müller, A. Lange in “Der NAHVERKEHR", 6 / 1994, Alba-Verlag, Düsseldorf). They are also used in tracked vehicles to drive the chain drive wheels. Electrical machines have operating areas with very good efficiency and operating areas in which the efficiency is significantly poorer. If such electrical machines are used in vehicles, the drive system is usually designed in such a way that the predominant part of the operation is in the areas of optimum efficiency. However, it cannot be avoided that the vehicle is also operated in areas where the efficiency is poor. For this reason, a gearbox is installed downstream of the electrical machines in some applications.
  • DE 196 19 321 C2 discloses a method for operating a vehicle with a plurality of electric drive machines, an electric drive machine being assigned to each wheel of an axle of the vehicle and an at least two-stage, switchable transmission being arranged after each drive machine.
  • the transmissions are shifted at different times, the switching process of the transmission following a first drive machine being monitored is and the switching process of a transmission subordinate to a second drive machine takes place only when the switching process of the first transmission is completed.
  • a two-stage transmission is preferably provided as the transmission, which can be implemented as an inexpensive design as a claw transmission, which is designed either synchronized or unsynchronized.
  • the available speed and torque range are relatively small, so that the drives for heavy vehicles, in particular for military use, are not sufficient.
  • the tractive force is not interrupted, only a part of the installed drive power is available during the switching process, as z.13. in the case of two prime movers, the tractive force of one prime mover is interrupted. This is particularly disadvantageous for tracked vehicles, since a steering movement is triggered by a difference between the drive of the right and the drive of the left chain.
  • a hybrid drive system is known from WO 97/09191, which contains an internal combustion engine, the output shaft of which drives an electric motor generator.
  • the electric motor drives a wheel axle via a continuously variable transmission (CVT), the electric motor being supplied electrically by the internal combustion engine on the one hand and by a battery on the other.
  • the battery is charged by the generator if excess energy is available.
  • Another vehicle drive unit is known from DE 196 29 235 AI, which has an internal combustion engine and a motor generator for converting electrical energy from a battery into mechanical energy in order to to deliver converted mechanical energy, or to convert mechanical energy into electrical energy to store the converted electrical energy in the battery.
  • the internal combustion engine and the motor generator are connected in terms of drive via a summation gear in planetary design, the output part of which is connected to the input part of a continuously variable transmission.
  • a belt or ring type gear is provided as a continuously variable transmission.
  • Electric motors that are assigned to a chain are fed by a first generator, while the other electric motors are fed by a second generator.
  • the invention has for its object to provide a reliable drive system with a large control range in terms of torque and maximum speed for a vehicle that has at least one right and left drive wheel, each of which is assigned at least one electric motor. It is solved according to the invention by the features of claim 1. Further refinements result from the subclaims.
  • the transmission comprises a mechanical, continuously adjustable transmission unit.
  • This gear unit can be a friction gear or preferably a gear with two pairs of conical disks and a wrap-around element.
  • the latter gear units also CVT (Con-called tinuous variable transmission), are often used in technology, including in vehicle construction, and are therefore proven components.
  • Tension chains or push link belts are particularly suitable as wrapping members.
  • the infinitely adjustable gear units have a large control range, so that they are also suitable for use in military wheeled and tracked vehicles where extreme demands are placed on the tractive force and the maximum speed. These maximum values cannot be covered by the control range of an electric motor alone, especially if the drives have to be used to steer the vehicle, as in the case of caterpillar vehicles. It is advantageous that the entire control range can be traversed without interrupting the tractive force.
  • the continuously variable change of the gear unit makes it possible for the electric motor or the electric motors to be driven in an area with an optimal efficiency.
  • tracked vehicles have an extremely high maneuverability due to the double control option via the electric motor and the continuously adjustable transmission unit, it being advantageous that the radius changes do not occur suddenly, but continuously.
  • the mechanical, infinitely adjustable gear unit is also advantageous for drive systems in which several electric motors act on a drive wheel via one gear unit each.
  • a pair of conical disks of a gear unit is expediently arranged on a common output shaft.
  • the adjustable Conical disks of the conical disk pairs adjacent to one another on the output shaft result in favorable spatial conditions for the arrangement of actuators and control lines as well as pressure lines.
  • Gear units can be dispensed with an additional summation gear for the individual electric motors.
  • the electric motors are electrically connected to at least two generators which, like the electric motors, are AC machines.
  • the output of a first generator is electrically connected to the input of a first rectifier, the output of a second generator to the input of a second rectifier.
  • the output of the first rectifier is simultaneously electrically connected to the input of a first left and a first right inverter, while the output of the second rectifier is simultaneously electrically connected to the input of a second left and a second right inverter.
  • each inverter is electrically connected to the input of an associated electric motor.
  • the tracked vehicle still remains drivable and steerable in the event of failure of any component of the drive system. If, for example, the first generator or an internal combustion engine driving it fails, the second generator and a second internal combustion engine driving it remain to drive the two drive chains.
  • the second generator powers the second left and second right electric motors that drive the right and left chain drive wheels. In this case, the vehicle only has a reduced drive power, but it is not unable to maneuver and it can reach the stationing location on its own.
  • FIG. 1 shows a schematic illustration of a tracked vehicle
  • FIG. 2 shows a schematic illustration of a detail II in FIG. 1.
  • the exemplary embodiment according to FIG. 1 is a tracked vehicle, the invention applies in the same way to wheeled vehicles which have an individual wheel drive.
  • the direction of travel of the tracked vehicle is designated 80.
  • a first, right electric motor 14 and a second, right electric motor 16 drive a right chain drive wheel 34 for a right drive chain 4 via a first, right reducing gear 22 and second, right reducing gear 24, respectively, and a right gear 30.
  • the transmission 30 comprises two mechanical, continuously variable transmission units, namely a first right CVT 50 and a second right CVT 52 (FIG. 2). If the chain drive wheel 34 is only driven by an electric motor 14 or 16, one of the CVTs 50, 52 is omitted.
  • a first left electric motor 18 and a second left electric motor 20 drive a chain drive wheel 36 for the left drive chain 2 via a first left reduction gear 26 and a second left reduction gear 28 as well as a left gear 32.
  • the left gear 32 is constructed in accordance with the right gear 30. It is therefore not shown in detail.
  • the electric motors 14, 16, 18, 20 are supplied with current by a first generator 6 and a second generator 8, which are driven by a first internal combustion engine 10 and a second internal combustion engine 12, respectively.
  • the electric motors 14, 16, 18, 20 and the generators 6, 8 are AC machines.
  • the output of the first generator 6 is electrically connected to the input of a first rectifier 38, while the output of the second generator 8 is electrically connected to the input of a second rectifier.
  • the output of the first rectifier is electrically connected both to the input of a first, left inverter 40 and to the input of a first, right inverter 42. Accordingly, the output of the second rectifier 44 is simultaneously electrically connected to the input of a second, left inverter 46 and a second, right inverter 48.
  • each inverter 40, 42, 46, 48 is connected to the input of an associated electric motor 14, 16, 18, 20, so that the first left inverter 40 with the first left electric motor 18, the second, left inverter 46 with the second , left electric motor 20, etc. is connected.
  • the redundancy of the drive elements and circuit elements, in the manner shown, ensures that in the event of a failure of a loving component of the drive system, the tracked vehicle still remains drivable and steerable.
