  • Patent number: 9447848
    Abstract: A transmission which has drive input and output shafts, a housing, two planetary gearsets (PR1, PR2), and at least three shifting elements which produce three gears or ratios. A ring gear of the gearset (PR1) and the input shaft are connected for forming a first shaft, a carrier of gearset (PR1) and the output shaft are connected for forming a second shaft, a ring gear of gearset (PR2) forms a third shaft, sun gears of gearsets (PR1, PR2) are connected for forming a fourth shaft, and carrier of gearset (PR2) couples the housing. The first shifting element is arranged in the force flow between the third shaft and the housing, the third shifting element is arranged in the force flow between the second and third shafts, and the second shifting element is arranged in the force flow either between the first and second shafts or the second and fourth shafts.

  • Patent number: 9435407
    Abstract: A transmission having a drive input shaft (AN), a drive output shaft (AB), a housing (G), at least two planetary gearsets (PR1, PR2), and at least three shifting elements (A, B, C) whose selective engagement produces various transmission ratios between the drive input shaft (AN) and the drive output shaft (AB), so that at least three gears can be obtained. To obtain a gear in each case, two shifting elements are engaged and a further shifting element is disengaged.
