- the speed ratio is preferably 1.55.
- the resulting gear ratio which is achieved by the second translation module 3 in the first gear stage, is thus about 13.4.
- the first clutch 36 separates the central gear 45 from the module housing 41, while the second clutch 37 rotatably connects the ring gear 42 to the central gear 45. This will block the planetary gear.
- the rotational movement of the ring gear 42 is transmitted to the planet carrier 44 via the planet wheels 46, which can not revolve around the central gear 45.
- the rotational speeds of the ring gear 42 and the planet carrier 44 are thus identical.
