Description

The present invention relates to a multi-stage transmission having an input shaft axis and an output shaft axis, which are arranged offset in axial direction with each other, wherein five further waves are provided. Furthermore, two spur gears and two planetary gear sets and at least five shift elements are provided.

For example, from the document DE 10 2011 079 720 A1 Such a multi-speed transmission is known, with the six forward gears and one reverse gear can be realized.

The present invention is based on the object to propose a multi-speed transmission of the type described above, which is as inexpensive as possible and has the smallest possible space requirement.

This object is achieved by the features of claim 1, wherein advantageous embodiments of the dependent claims and the description and the drawings.

Thus, a multi-stage transmission with an input shaft axis and an output shaft axis is proposed, which are arranged, for example, for a front or rear transverse arrangement in a vehicle off-axis to each other. The multi-speed transmission is thus preferably carried out with a lateral output. Further, a first shaft connected as a drive to, for example, the vehicle engine is arranged coaxially with the input shaft axis, with a second shaft arranged as an output coaxial with the output shaft axis, e.g. can be coupled with an output differential Diff or the like. Further, five further shafts and a first spur gear and a second spur gear are provided to communicate with each other the elements associated with the input shaft axis and the output shaft axis. Further, a first planetary gear and a second planetary gear and at least five switching elements are provided so that at least six forward gears and at least one reverse gear are switchable.

In the nevertheless a small space and a good efficiency having multi-speed transmission is provided that the first shaft is connectable to a first element of the second Planentenradsatzes, wherein the first shaft is connectable or connected to a first element of the first Planentenradsatzes. The second shaft is arranged coaxially with the output shaft axis and connected or connected to a second element of the first Planentenradsatzes and connected to a third element of the second Planentenradsatzes, wherein a second element of the second Planentenradsatzes is connectable to the housing. A third element of the first planetary gear set is connectable or connectable to the second element of the second planetary gear set, the second element of the second planetary gear set being connectable to the first shaft via the first spur gear stage or via the second spur gear stage.

The proposed multi-speed transmission thus comprises only two Planetenradsatzebenen and two spur gears and five switching elements, wherein for realizing the gear stages at the same time two of the switching elements are closed or activated. Regardless of the various design variants of the multi-speed transmission results in a total compact design with low component load and low gear losses and good gear efficiency and also a good translation series, with a structurally simple connection of at least one electric machine for hybridization of the multi-speed transmission is possible. One of the spur gear stages is preferably suitable for axially parallel connection of the electric machine. It is also possible that, if necessary, a coaxial connection of the electrical machine is provided.

However, if an even larger translation or a space reasons greater center distance between the electric machine and the input and output shaft axes are desired, also a further translation stage or an intermediate gear can be provided for connecting the electric machine. If the electric machine is firmly translated to the drive, all internal combustion engine gears can also be electrically realized.

The multistage transmission or the first shaft of the multistage transmission, for example, be preceded by a torsional vibration decoupling unit. In the case of a hybridization, an additional switching element is preferably positioned between the electric machine and the internal combustion engine as a separating clutch, with which the internal combustion engine or the drive motor of the vehicle can be decoupled from the first shaft. In this way, both pure combustion engine driving and purely electric driving is possible. In the case of hybridization are preferably a fifth switching element or a first alternative of the fifth switching element or a second alternative of the fifth switching element or a third alternative of the fifth switching element forward and a fourth switching element or a first alternative of the fourth switching element backwards as internal starting elements

As switching elements both friction and form-fitting switching elements can be used. Preferably, due to their characteristics, the second switching element designed as a brake and / or the fifth switching element or the first alternative of the fifth switching element or a second alternative of the fifth switching element or a third alternative of the fifth switching element can be designed as a form-locking claw switching element.

In the present invention, the two planetary gear sets may be designed as negative planetary gear sets. The minus planetary gear set can preferably be transferred to a positive planetary gear set in the first planetary gear set when the planet carrier and the ring gear connection on this wheel set are interchanged and the amount of stand ratio is increased by one. This means for those skilled in the art that in a negative planetary gear set, a first element as a sun gear, a second element as a planet carrier or web and a third element are designed as a ring gear. In the case of a positive planetary gear set, however, it applies that a first element is designed as a sun gear, a second element as a ring gear, and a third element as a web or planet gear carrier. Based on this information, for example, a proposed negative planetary gear set can be converted in the multi-stage transmission according to the invention in a positive planetary gear.

A minus planetary gear set is known to have on its planet gear rotatably mounted planetary gears, which mesh with the sun gear and the ring gear of this planetary gear, so that the ring gear rotates at fixed planet carrier and rotating sun gear in the direction opposite to Sonnenraddrehrichtung. A plus planetary gear set is known to be rotatably mounted on its planet and rotatably mounted in meshing inner and outer planetary gears, the sun gear meshing with the planetary gears and the ring gear of this planetary gear with the outer planetary gears, so that the ring gear with held planet carrier and rotating sun gear in the direction of Sonnenraddrehrichtung same direction turns.
