Problems solved by technology

In motor vehicle transmissions known from the prior art, such drag losses occur particularly strongly in the second brake, because the second brake has to be constructed with a particularly large active surface due to the high torque load, and because the second brake ON only in 1st forward gear and in reverse gear

Embodiment Construction

[0041] figure 1 A transmission G according to a first exemplary embodiment of the invention is shown schematically. The transmission G has a first planetary gear set P1, a second planetary gear set P2 and a third planetary gear set P3. Each of the three planetary gearsets P1 , P2 , P3 has a first element E11 , E12 , E13 , a second element E21 , E22 , E23 and a third element E31 , E32 , E33 . The first element E11 , E12 , E13 is always formed by the sun gear of the corresponding planetary gear set P1 , P2 , P3 . If the planetary gear sets are designed as negative gear sets, the second elements E21 , E22 , E23 are formed by the planetary carriers of the respective planetary gear sets P1 , P2 , P3 and the third elements E31 , E32 , E33 is formed by the ring gears of the corresponding planetary gear sets P1, P2, P3. In transmission G's in figure 1 In the embodiment shown in , the planetary gear sets P1 , P2 , P3 are designed as negative gear sets. If the planetary gear set is...

Abstract

The invention relates to a transmission for a hybrid vehicle, to a drive train for a hybrid vehicle having such a transmission, and to method for starting up a hybrid vehicle transmission (G) for a hybrid vehicle, wherein the transmission (G) has a drive shaft (GW1), an output shaft (GW2), three planetary wheel sets (P1, P2, P3), an electric machine (EM) having are rotationally fixed stater (S) and a rotatable rotor (R) and five switching elements (03, 04, 05, 14, 15), wherein six forward gears (1 to 6) and a reverse gear (R1) can be formed by selective pairwise closure of the five switching elements, drive train for a hybrid vehicle having such a transmission (G), and to a method for starting up a hybrid vehicle having such a drive train.

Description

technical field [0001] The invention relates to a transmission for a hybrid vehicle, a powertrain system for a hybrid vehicle having such a transmission, and a method for starting a hybrid vehicle. A transmission is referred to here in particular as a multi-stage transmission, wherein a plurality of gears, ie fixed transmission ratios, between a drive shaft and an output shaft of the transmission can be shifted preferably automatically via shift elements. The switching element is here, for example, a clutch or a brake. Such transmissions are mainly used in motor vehicles in order to suitably adapt the rotational speed and torque output characteristics of the drive unit to the driving resistance of the vehicle. Background technique [0002] Patent application DE19912480A1 describes an automatically shiftable motor vehicle transmission with three single-planet carrier planetary gear sets, with three brakes and two clutches for shifting six forward gears and one reverse gear a...
