Abstract
Device for starting up a vehicle equipped with an automatic transmission provided between a drive shaft (1) and a driven shaft (2) in a transmission housing (7) with a planetary gear (4) with a first gear (14) coupleable with the drive shaft (1), with a second gear (13, 15) coupleable with the driven shaft (2) and with the third gear (12), wherein the third gear (12) is connectable with the transmission housing (7) via a start-up brake (S), of which the brake force is controllable.
Claims15
Device for starting up a vehicle equipped with an automatic transmission provided between a drive shaft (1) and a driven shaft (2) in a transmission housing (7)
- with a planetary gear (4) with a first gear (14) coupleable with the drive shaft (1), with a second gear (13, 15) coupleable with the driven shaft (2) and with a third gear (12),
- thereby characterized, that the third gear (12) is coupleable with the transmission housing (7) via a start-up brake (S), of which the brake force is controllable.
Device according to one of the preceding claims, thereby characterized, that the start-up brake is a friction brake (S), with controllable slip.
Device according to one of the preceding claims, thereby characterized, that the brake force of the start-up brake (S) is controllable in such a manner, that the brake force at the beginning of the start-up process is smaller than at the end of the start-up process.
Automatic transmission (26), with a device (4, S) according to one of the preceding claims.
