Definitions

  • the invention relates to a transmission unit, in particular a motor-transmission unit with an electric machine.
  • Motor-transmission units of this type can be used in motor vehicles, among other things, and are part of the drive train there, via which the drive wheels can be driven.
  • the invention also relates to a shifting method for shifting the transmission unit.
  • a transmission for driving a vehicle is known from DE 102020 104727 A1, in which two connected planetary gear sets are used in order to shift two different gears with an advantageous transmission ratio distribution in a simple transmission structure. It is proposed to permanently connect the planetary carriers of the two planetary gears with one another, so that a large translation and, at the same time, a large spread are made possible.
  • the invention is based on the object of specifying a transmission unit in which different gears can be shifted with an advantageous ratio distribution with a simple transmission structure.
  • a further object is to propose a shifting method for shifting the transmission unit.
  • the object is achieved according to the invention by an embodiment corresponding to independent claim 1 and the switching method according to claim 9 . Further advantageous embodiments of the present invention can be found in the dependent claims.
  • a transmission unit is proposed, which is accommodated in a transmission housing.
  • the transmission unit comprises an input shaft, an output shaft, a first planetary gear set and a second planetary gear set, with the planetary gear sets each having a plurality of elements, with a sun gear of the second planetary gear set being non-rotatably coupled to the input shaft and a planet carrier shaft of the first planetary gear set being coupled to the output shaft in a torque-proof manner.
  • a first switching element is provided between the transmission housing and the sun gear of the first planetary gear set and a further switching element, by means of which at least one further element can be switched into the power flow between the input shaft and the output shaft.
  • the transmission unit can be shifted into a neutral position by opening all shifting elements, in which the input shaft is completely decoupled from the output shaft. No-load losses are minimized in this switching position. This can be an advantage if another unit is to be driven independently via the electric machine, e.g. an air conditioning system.
  • a second switching element can be provided between the transmission housing and the ring gear of the second planetary gear set. If the first and second switching elements are shifted, this causes a transmission between the drive shaft and the planetary carrier shaft of the first planetary gear set. This can be a translation of 3.5:1 to 5.5:1, for example.
  • a third switching element can be provided between the drive shaft and the coupling shaft, an operative connection between the first and second planetary gear set. If the first and third shifting elements are shifted, a second gear ratio is created between the drive shaft and the planet carrier shaft of the first planetary gear set. This can be a ratio of 2.0:1 to 3.5:1, for example.
  • the coupling shaft is preferably designed in such a way that it encompasses the planet carrier of the second planetary gear set and the ring gear of the first planetary gear set, so that a non-rotatable connection is formed between the planet carrier and the ring gear.
  • a fourth shifting element can be provided between the ring gear of the second planetary gear set and the planet carrier shaft of the first planetary gear set. If the first and fourth shifting elements are shifted, a further transmission ratio is created between the drive shaft and the planetary carrier shaft of the first planetary gearset. This can be a ratio of 1.1:1 to 2.0:1, for example.
  • a gear ratio of 1:1 can be shifted between the drive shaft and the planet carrier shaft of the first planetary gear set by shifting the two shifting elements.
  • the switching elements can be designed as frictional, form-fitting or a combination of both switching element types.
  • the sun gear shaft of the first planetary gear set can be designed as a hollow shaft and the planet carrier shaft of the first planetary gear set can be guided through the hollow shaft.
  • the planet carrier shaft can be designed as a hollow shaft and the sun gear shaft can be guided through the hollow shaft.
  • the planet carrier shaft of the first planetary gear set and the output shaft Output ratio is provided.
  • This can be, for example, a spur gear with a fixed ratio.
  • one of the elements of the planetary gearsets can be fixed relative to the transmission housing.
  • two elements of the planetary gearsets can be fixed relative to one another, so that the planetary gearsets are blocked.
  • operatively connected means that two gear elements can be directly connected to one another or that there are other gear elements between two gear elements, for example one or more shafts or gears Speed provided by one gear to the other gear.
  • Figures 1 and 2 show a first and second embodiment of the transmission unit 1 with the drive motor 14.
  • the drive motor 14 is an electric motor or an electric machine. Not shown are the other components of a motor vehicle drive train, such as the drive wheels, a differential and/or a Propeller shaft. The subsequent components of a drive train are coupled to the transmission unit 1 via the output shaft 11 .
  • gear units 1 are shown as simplified gear structures.
  • the two versions differ in the arrangement of the switching element 5 in relation to the gears of the output transmission 16, via which the torque is transmitted from the planet carrier shaft 10 to the output shaft 11.
  • the sun gear shaft 15 of the first planetary gear set 3 is designed as a hollow shaft, through which the planet carrier shaft 10 of the second planetary gear set 3 is guided.
  • the planet carrier shaft 10 of the first planetary gear set 3 is designed as a hollow shaft, through which the sun gear shaft 15 of the first planetary gear set 3 is guided.
  • Both shafts can be mounted in relation to the transmission housing or, alternatively, in relation to one another.
  • Both versions are identical in terms of the coupling of the elements of the planetary gear sets 2, 3 and the shifting elements 4, 5, 6, 7 or, to put it another way, the elements of the planetary gear sets 2, 3 can be shifted with the aid of the shifting elements 4, 5, 6, 7 are brought into operative connection with one another in the same way.
  • the function of the transmission unit 1 can thus be combined for both versions.
  • the transmission unit 1 By means of the transmission unit 1, starting from an idle shift position in which all four shift elements 4, 5, 6, 7 are shifted into the open position, 4 gear ratios can be shifted. For each transmission step it is necessary for two shifting elements to be shifted at the same time, with only one shifting element having to be opened and another closed to change the transmission step.
  • the speed can be adjusted by means of the electric motor, so that the shaft speeds do not need to be synchronized via frictional contact surfaces and positive-locking shifting elements without a synchronization function can therefore be used, making the overall efficiency particularly high.
  • positive-locking shifting elements that are used can be designed as claw shifting elements.
  • the first shifting element 4 is provided between the transmission housing 12 and the sun gear 3.3 of the first planetary gear set 3.
  • This first shifting element 4 must be shifted together with an optional further shifting element 5, 6 or 7 (according to the table) in order to reduce the speed of the electric motor and thus increase the torque with which the output shaft 11 is driven.
  • the sun wheel shaft 15 is rotationally coupled to the transmission housing 12 in the shifted state of the shifting element 4 .
  • the shifting element 5 can be arranged between the transmission unit 1 and the output transmission 16 or, alternatively, behind the output transmission 16 .
  • the second switching element 5 is provided between the transmission housing 12 and the ring gear 2.1 of the second planetary gear set 2, so that the ring gear 2.1 can be fixed relative to the housing 12.
  • the first gear is engaged for starting the vehicle.
  • the fourth shifting element 7 is provided between the ring gear 2 . 1 of the second planetary gear set 2 and the planetary carrier shaft 10 of the first planetary gear set 3 .
  • Ring gear 2.1 is coupled to planet carrier shaft 10 in a torque-proof manner when switching element 7 is in the engaged state. If the switching elements 4 and 7 are engaged, the second gear is engaged.
  • the third switching element 6 is provided between the drive shaft 8 and the coupling shaft 9, the operative connection between the first and second planetary gear sets (2, 3). This enables the ring gear 3.1 of the first planetary gear set 3 to be driven directly.
  • One of the special features of the proposed transmission unit is that when shifting into 4th gear, a direct coupling of input shaft 8 and output shaft 11 is engaged via planetary carrier shaft 10, so that a translation of 1:1 is active. As a result, sliding rolling losses only arise in the contact of the output transmission 16, as a result of which a high maximum efficiency of the transmission unit 1 can be achieved based on the losses in the gearing contact of around 99%.
  • a device which is generally known to the person skilled in the art is provided for switching the switching elements.
  • the transmission housing can be constructed differently.
  • the output transmission 16 can be accommodated, for example, in a separate housing.
  • a transmission housing is also conceivable, in which the output transmission 16 is also arranged.
