Definitions

  • the present invention relates to a drive system for a motor vehicle.
  • the drive system comprises a first axis and a second axis, each having at least two wheels and a first drive means associated with the first axle and second axle and a second drive means associated with the second axle.
  • German published patent application DE 10 2005 026 874 A1 discloses a device for driving a vehicle in which a variable distribution of the drive between a front axle and a rear axle can be regulated via a vehicle engine. By coupling two electric motors by means of three Clutches is a variable distribution between the left and right drive wheels possible.
  • the object of the present invention is to provide a drive system for a motor vehicle, which has a multi-functional axle drive for use in vehicles with torque distribution, which is less expensive.
  • the object is achieved by a drive system for a motor vehicle, comprising the features in claim 1.
  • a drive system as used for a motor vehicle according to the invention, has a driven first axis and a driven second axis.
  • both the first and the second axis each have two wheels. It is also conceivable that several wheels are provided on each axis.
  • On the first axis acts an associated first drive means, which is also for driving the second axis selectively switched on or off.
  • the second drive means has only a single electric motor for selectively driving both wheels of the second axle.
  • Optional drive means that the electric motor can be switched off and the second axle is driven only by the first drive means.
  • the first drive drives and the electric motor is switched on for torque vectoring.
  • the electric motor is used to boost the power input of the likewise connected first drive unit.
  • the arrangement according to the invention can be used for torque distribution, for torque shifts, in particular for transverse moments, for boosting and recuperation, and as a purely electric drive.
  • the first drive device is provided with an internal combustion engine.
  • the first drive means may be provided with an electric motor. It is also conceivable that in a further embodiment of the invention, the first drive means is provided with an internal combustion engine and with an electric motor.
  • an associated second drive device with the electric motor acts on the second axis, wherein the first drive device can be mechanically coupled to the second drive device.
  • the second drive device has a geared connection between the first drive unit, the electric motor and the wheels.
  • the geared connection is for example a differential.
  • a torque vectoring gear may be formed in the geared connection.
  • the geared connection is preferably formed by at least two or more coupled planetary gears.
  • the first drive device of the drive system to a combustion and / or electric motor, wherein a coupled, switchable first clutch between the combustion and / or electric motor and a change gear can be arranged with multiple switchable translations.
  • the change gear can be either a manual, conventional transmission, a known automatic transmission, an automatically shifted transmission or the like.
  • change gear used any type of speed and torque matching gear ratio for reducing the relatively high speeds of the combustion and / or electric motor and to increase the drive torque includes.
  • the first drive device is associated with a coupled with the change gear first differential of the first axis and communicates with the at least two wheels of the first axis in operative connection.
  • the second drive device comprises a second differential and is mechanically coupled or coupled to the first differential of the first drive unit via a propeller shaft.
  • the second drive device of the drive system of a motor vehicle on a second differential and a single electric motor wherein between the second differential and the electric motor, a torque vectoring gear and a switchable second clutch is arranged with the wheels of the second Axis is in operative connection.
  • the torque vectoring transmission behaves like a conventional open differential when driving straight ahead and can only be activated by means of the switchable second clutch.
  • the switchable second clutch is like the first clutch formed for example by a multi-disc and / or multi-plate clutch.
  • the second drive means comprises a shaft parallel to the second axis, which are coupled via a first spur gear and a second spur gear each with the second axis of the vehicle. Due to this advantageous design, additional torques can be directed into the second differential by a wide variety of drive options.
  • the advantage of this invention is that especially in all-wheel drive vehicles with an internal combustion engine by connecting the electric motor on the second axis (preferably the rear axle of the vehicle) more power can be introduced (Boosten) or operated the engine with less power and thus saved fuel and the running time can be extended without refueling, by driving only with the electric motor fuel can be saved and driving the electric motor can be recovered as a generator of energy.
  • Boosten more power can be introduced
  • the drive system according to the invention is interchangeable with finished drive concepts and compared to the drive concepts of the prior art only with electric drive via an electric motor can be driven.
  • the arrangement is easier, especially when the geared connection is formed by planetary stages.
  • FIG. 1 shows a schematic view of the arrangement of the drive system according to the invention in a motor vehicle

  • Figure 3 shows a control option of the second drive means of the drive system according to the invention.
  • Figure 4 to Figure 7 further control options of the second drive device of the drive system according to the invention.
  • FIG. 1 shows schematically the arrangement of the drive system 2 according to the invention in a motor vehicle 1.
  • the drive system 2 comprises a first axis 20 and a second axis 40, wherein each of the first axis 20 and the second axis 40, two wheels 3 are assigned.
  • first differential 22 On the first axis 20 a coupled to the change gear 23 first differential 22 is disposed and is in operative connection with the two wheels 3 of the first axis 20.
  • a switchable first clutch 24 is provided between the change gear 23 and the combustion and / or electric motor 21, a switchable first clutch 24 is provided.
  • a fuel tank 28 is disposed at any position in the vehicle 1.
  • the first differential 22 is disposed on the first axis 20 and a second differential 42 is disposed on the second axis 40. Both differentials 22, 42 are mechanically coupled or coupled via a propeller shaft 4 and a hypoid stage 45. Between the second differential 42 and an arranged electric motor 41, a torque vectoring gear 43 and a switchable second clutch 44 are provided, which are in operative connection with the wheels 3 of the second axle 40.
