Definitions
- the invention relates to a system for variable torque distribution within at least one axle of a vehicle.
- a first drive unit is driven by a planetary gear and a differential each wheel of the axle with a same torque.
- German patent application DE 10 2006 028 790 A1 discloses a device for distributing a drive torque to at least two drive shafts of a vehicle axle.
- an axle drive is proposed that includes a differential having two electric motors, each associated with an output shaft. The respective output shaft is connected to an element of the differential.
- the differential basket of the differential is driven by a drive.
- the differential basket has an inner pair of differential gears and an outer pair of differential gears, each two differential gears of the pairs of differential gears are arranged on a common axis.
- the output of each side of the axle is connected to the inner differential gear pair, each electric motor being connected via a hollow shaft to a differential gear of the outer differential gear pair.
- the German patent application DE 103 19 684 A1 discloses a transmission for distributing a drive torque to at least two output shafts with at least two at least three-shaft planetary gear sets.
- One wave each a planetary gear set is connected to a drive shaft.
- one shaft of a planetary gearset represents one of the drive shafts and in each case at least one further shaft of a planetary gearset is operatively connected to a shaft of a further planetary gearset.
- An operating state-dependent torque of a shaft can be supported in such a way in dependence on an operating state of the respective other shaft connected via the operative connection that, when a speed difference occurs between the drive shafts via the active connection, a torque changing the speed difference is applied to the planetary gear sets.
- the electrically variable transmission consists of a drive element for receiving power from a machine. Furthermore, an output element is provided. Likewise, a first and a second motor or generator is provided. Likewise, the electrically variable transmission includes a first and a second differential gear set, each having a first, a second and a third element. The drive element is not permanently connected to any element of the gear sets.
- the output element is constantly connected to an element of the gear sets.
- a first connecting element which connects the first element of the first gear set constantly with the first element of the second gear set, is provided.
- a second connecting element is provided, which connects the second element of the second gear set constantly with the second element of the first gear set or with a stationary element.
- the first motor or generator is constantly connected to an element of the first or second gear set.
- the second motor / generator is selectively connected to two of the elements of the first or second gear set.
- the second motor / generator is selectively connected to two of the elements of the first or second gear set.
- a second torque transmitting device which is an element of the first or second gear set selectively connects to the Anthebselement, this element is different from the one which is connected by the first torque transmitting device.
- a third torque transmitting device is provided which selectively connects a member of the second gear set to a member of the first gear set with a stationary member or to the drive member.
- a fourth torque transmitting device is connected in parallel with a first and second motor / generator to selectively prevent their rotation.
- a fifth torque transmitting device is connected in parallel with the other of the motors / generators to prevent their selective rotation.
- First, second, third, fourth and fifth torque transfer devices are configured to provide an electrically variable transmission having a continuously variable range of speed ratios and four fixed forward speed ratios.
- the invention has for its object to provide a system for variable torque distribution within at least one axis of a transmission that has a modular design and has a high power density.
- variable torque distribution system comprising the features of claim 1.
- the drive unit is designed as an electric drive unit which distributes the drive power within the axle by means of an overlay stage and a further electric motor.
- this function can be used, inter alia, to generate driving-stabilizing yawing moments about the vertical axis of the vehicle. This can be done in the acceleration case as well as during braking maneuvers or in Rekuparationsfall. Recuperation would be with appropriate programming of the control of the vehicle even when cornering without oversteering or understeering influencing the driving behavior possible.
- the superimposition stage is designed so that the superposition stage associated electric motor provides free differential function for the torque distribution at the differential.
- the electric motor on the differential of the superposition stage is designed so that it stops when the same torque is applied to the wheels of an axle. In the event that this motor is activated, resulting from the planetary gear a specific speed of the differential gears in the differential unit. This causes a specific differential speed at the wheels of the respective drive axle regardless of the turning radius and the speed of the vehicle.
- the system for variable torque distribution within at least one axle of a vehicle comprises a second drive unit, which has a smaller power than the first drive unit.
- the second drive unit acts on a superimposition system, so that the torques within the wheel can be distributed on a wheel-specific basis.
- the first drive unit can be designed as an electric motor or as an internal combustion engine.
- the second drive unit is an electric motor.
- the second drive unit does not have to be carried along, i. H. the second drive unit stands still when the wheel-specific torques within an axle are the same.
- the overlay system on which the second drive unit acts is made up of two identical planetary gearboxes.
- the wheel-specific distribution of torques is infinitely adjustable via the torque of the second drive unit.
- the power of the second drive unit is at least ten times smaller than the power of the first drive unit. If the first drive unit and the second drive unit are each designed as electric motors, they have the form of hollow shaft motors.
- FIG. 1 schematically shows the construction of a system for variable torque distribution within at least one axle of a vehicle.
- Figure 2 shows the schematic view of a vehicle, each with an electric motor drive on each axis.
- FIG. 1 shows a schematic view of the system 1 for variable moment distribution within at least one axle 10 of a vehicle (not shown).
- a first drive unit 3 is provided, which transmits a torque to a differential 20 via an upstream planetary gear 7.
- the planetary gear shown in Figure 1 7 represents only one possible embodiment of a transmission. It is obvious to a person skilled in the art that in the invention, other types of gear can be used.
- the planetary gear 7 is provided with a first clutch 2 and a second clutch 4, so that different translations can be provided.
- the differential 20 the corresponding torques are transmitted to the axle 10 and the wheels RL and RR.
- a second drive unit 5 is provided, which is connected to a superposition system 11.
- the overlay system 11 consists of a first planetary gear 21 and a second planetary gear 22.
- the operation of the second drive unit 5, the overlay system 11 is also actuated, thereby wheelindividually the torques within the axis 10 to the individual wheels RL, RR of the axis 10 are distributed ,
- the first drive unit 3 is designed as an electric motor.
- the second drive unit 5 is formed as an electric motor.
- the power of the first drive unit 3 is at least ten times greater than the power of the second drive unit 5.
- the second drive unit 5 is silent. This means that when driving straight ahead, the second drive unit 5 does not have to be carried along, which ultimately leads to energy savings.
- FIG. 2 shows the schematic representation of a vehicle in which the two systems for the variable torque distribution within at least one axle 10 are provided with electric motors, which thus form the first drive unit 3 and the second drive unit 5.
- a controller 12 is provided which cooperates with the variable torque distribution systems on each axle 10. From the control unit corresponding commands are supplied to the second drive unit 5 in order to distribute the torque distribution required for the respective driving situation to the two wheels RL, RR of an axle 10.
- the control unit 12 is associated with a battery 14, which provides the power supply for the first drive unit and / or second drive unit 5 in the drive case. In Rekuparationsfall the battery is charged via the control unit. Thus, the braking energy is again converted into electrical energy, which can be stored in the battery 14.
