| 121 | TRANSMISSION SYSTEM FOR A VEHICLE | US13590562 | 2012-08-21 | US20120316022A1 | 2012-12-13 | Roell Marie Van Druten; Alexander Franciscus Anita Serrarens; Bas Gerard Vroemen |
| A transmission system comprises two transmission modules which are arranged in series, an output shaft of the first transmission module being connected via a mount point to an input shaft of the second transmission module. The transmission system further includes an electromotor which is connected to the mount point. The first transmission module is formed by a two-step reduction mechanism and comprises a planetary gear set with at least three rotational members one of which is connected to a brake. The first transmission module further includes a short-circuit clutch which is positioned between the other two rotational members. The brake may be used for launching the vehicle. | ||||||
