Definitions
- the present invention relates to a planetary multi-speed transmission for a vehicle according to the closer defined in the preamble of claim 1.
- a power-shiftable multi-speed transmission is known.
- the drive shaft is connected via a torsional vibration damper fixed to a first shaft of a first shaft train.
- a parallel arranged second shaft strand includes, among others, designated as the shaft two output shaft.
- the two wave strands are connected to each other via three spur gear stages.
- On the first shaft train is a first three-shaft planetary gear.
- On the second shaft train is a second planetary gear and a third planetary gear.
- the multi-speed transmission thus comprises ten shafts, which communicate with each other via three spur gears and three planetary gears.
- the envisaged switching elements are hydraulically actuated. To reduce hydraulic losses, the switching elements are to be arranged easily accessible from the outside. However, in a front-transverse installation of the transmission in a vehicle only a limited axial space is available.
- the present invention is based on the object to provide a multi-speed transmission with the highest possible number of gear ratios and good accessibility of the switching elements at the same time good gear efficiency and the lowest possible axial space requirement.
- a powershiftable multi-speed planetary gear or a multi-speed planetary gear for a vehicle with a housing is beaten, wherein the drive or the drive shaft and the output or the output shaft are arranged axially parallel to each other for a preferred front transverse installation.
- the multistage transmission according to the invention comprises only nine shafts, three planetary gear sets and only six shift elements in order to realize at least nine forward gears and one reverse gear can. Furthermore, preferably only two machine elements are provided for coupling drive and output.
- the good accessibility of the switching elements can be realized, inter alia, on the one hand by the use of brakes as switching elements and on the other hand by the use of couplings as switching elements, which are preferably positioned on outer shafts preferably on the drive and the output in the multi-step transmission according to the invention. Due to the low construction costs result in an advantageous manner low production costs and low weight of the multi-speed transmission according to the invention.
- the planetary gear sets are arranged in the order of the first planetary gear set, the second planetary gear set and the third planetary gear set arranged in the axial direction, wherein preferably only minus planetary gear sets are provided.
- a minus planetary gearset is known to have on the planetary gear rotatably mounted planetary gears, which mesh with the sun gear and the ring gear of this planetary, so that the ring gear rotates with held planet carrier and rotating sun gear in the direction opposite to the sun gear.
- a plus planetary gear set is known to be rotatably mounted on its planet gear and meshing with each other inner and outer planetary gears, the sun gear of this planetary mesh with the inner planet gears and the ring gear of this planetary gear with the outer planetary gears, so that the ring gear with held planet carrier and rotating sun gear in the direction of Clarradfilraum same direction turns.
- a hydrodynamic torque converter or a hydrodynamic coupling can be used in the multistage transmission according to the invention. It is also conceivable that an additional starting clutch or an integrated starting clutch or starting brake be used. It is also possible that an electric machine or another power / power source is arranged on at least one of the shafts. In addition, a freewheel to the housing or to another shaft can be arranged on at least one of the waves.
- nine forward gears and at least one reverse gear can be engaged via the shift mechanism provided. elements are switched. However, it is conceivable that, for example, for the fourth forward gear further switching combinations are made possible by the combination of other switching elements.
- switching element is to be understood as meaning a switchable connection between two elements of the transmission, wherein the torque to be transmitted between these two elements is transmitted by means of frictional connection or frictional engagement or by means of positive locking. If both elements of the switchable connection are rotatable, then the switching element is referred to as a coupling and if only one of the two elements of the switchable connection rotates, the switching element is referred to as a brake.
- the geometric position or sequence of the individual switching elements is freely selectable, as long as it allows the bindability of the elements. In this way, individual elements can be moved arbitrarily in their position.
- a plurality of wheel sets can also be arranged radially one above the other, ie nested.
- Embodiments of a force-locking switching element are multi-plate clutches or brakes, band brakes, cone clutches or brakes, electromagnetic clutches, magnetic powder clutches and electro-rheological coupling.
- Embodiments of a positive switching element are jaw clutches or brakes and gear couplings. Due to their characteristics, especially the first switching element and the fifth switching element as form-locking switching elements, e.g. Claw switching elements be executed, whereby significant consumption advantages can be achieved.
- both friction and form-locking switching elements can generally be used.
