The sun gear of planetary gearsets is answered to be formed.If one of planetary gearsets are configured to negative ratio gear group, the second element is excellent
Gated its planet carrier to be formed, third element is formed by its gear ring.If one of planetary gearsets, which are configured to positive drive, compares tooth
Wheel group, then the second element preferably formed by its gear ring, third element is formed by its planet carrier.
Preferably, the first planetary gearsets and the second planetary gearsets are respectively configured to negative ratio gear group, wherein, the
Two planetary gearsets are arranged radially in outside the first planetary gearsets.It is particularly due to the first element of the second planetary gearsets
Permanently connected between the third element of the first planetary gearsets, such arrangement is advantageous to structure compact vertically
Make.
According to a kind of preferred scheme, at least one switching device in each switching device is coaxially disposed with drive shaft.Here,
Remaining switching device is set with the planetary gearsets system coaxial.The axial arrangement of speed changer can be grown by this distribution
Degree is optimized to minimum.
Especially preferably, the second switching device and/or the 4th switching device are coaxially disposed with drive shaft.Pass through this set
The construction especially compact vertically of speed changer can be achieved.
3rd switching device and/or the 5th switching device and are arranged on planetary gearsets system coaxial in the axial direction
The construction short in the axial direction of speed changer is equally beneficial between second spur gear group and planetary gearsets system.
Preferably, the first switching device is set with planetary gearsets system coaxial, is exactly arranged on the second commutating tooth
Wheel group on that side of planetary gearsets system.This set is equally beneficial for the structure short in the axial direction of speed changer
Make.
Preferably, the first switching device and/or the 3rd switching device are configured to the sealed switching device of shape.Shape is sealed to cut
Element is changed to connect by sealed establish of shape in closure state, and outstanding advantages are than force closure switching device in open mode
Lower towing loss.Lost by low towing in open mode, the efficiency of speed changer improves.According to a kind of reality of replacement
Mode is applied, the first switching device and/or the 3rd switching device can be structured as the friction switching device of force closure, friction switching
The friction plate of element only has the rubbing surface without liner.In other words, rub switching device each friction plate plate-shaped base body
Without the friction facing on friction plate.However, it is possible to rub to the indivedual of such friction switching device or all
The rubbing surface of piece is heat-treated, such as is nitrogenized.Such friction switching device is designed for high compressive load per unit area, and
Therefore it can be configured to that there is small rubbing surface and a small amount of friction plate.Thus, the towing loss of such switching device exists
It can be reduced in open mode.
Preferably, this speed changer, which has, includes the motor of non-rotary stator and rotatable rotor, wherein, the rotor and
Drive shaft permanent action connects or can switchably acted on connection.Here, permanently connected or changeable connection can construct
It is indirectly connected with to be directly connected to or being configured to.When being configured to be indirectly connected with, rotor by fixed gearratio, for example by attached
The planetary gearsets added for good and all or are switchably connected in drive shaft, wherein, an element of the planetary gearsets is fixed
Into non-rotary.Such as the sun gear of the planetary gearsets can for good and all be fixed into non-rotary, its planet carrier can be with drive shaft

With a spur gear of one of described two spur gear groups directly or by one or more idler gears or by among one
Axle, a spur gear particularly preferably with the second spur gear group act on connection.Therefore, motor can be simply set to axis
Parallel to drive shaft, the construction particularly compact in the axial direction thus, it is possible to realize speed changer.Can be with by the connection of idler gear
Improve the acoustics of engagement.
This speed changer can have torsional vibration damper, and the torsional vibration damper is designed for torsional vibration damper and preferably
It is arranged in the effect connection between two sections of drive shaft.Towards just so as caused by the driver element outside speed changer
The twisting vibration of gear train can be by vibration damping.
In principle, initiating element (such as fluid torque-converter or friction clutch) can be connected to speed change in the known manner
Device upstream.Such initiating element can also be the overall part of speed changer.Initiating element is used in motor-driven in speed changer
Starting process can be realized when in car power assembly system in the following way, i.e. can realize between internal combustion engine and driven shaft
Slipping state.Preferably, but such initiating element is constructed within speed changer in the following way, i.e. the first switching
Element is configured to the switching device that rubs.Run by the skidding of the first switching device, can be achieved in the first gear and in reversing gear
Starting process.Therefore single initiating element can be saved.If the first switching device is configured to the sealed switching device of shape, or
The switching device does not allow to adjust slipping state exactly, then can be along direction of advance by the 3rd switching device when starting
Starting process and be to realize slipping state along the starting process of reverse direction by the 4th switching device, the 3rd switching
Element or the 4th switching device can be configured to suitable force closure switching device for this.
This speed changer can be the part of automotive drive train.Power assembly system is gone back in addition to speed changer
Including internal combustion engine, the internal combustion engine is connected or can be connected and the drive shaft turnable elastic with speed changer by torsional vibration damper.
One can be set to separate clutch between drive shaft and internal combustion engine, the separation clutch can be the part of speed changer.
The driven shaft of speed changer is connected with differential mechanism in driving effect, the wheel effect connection of the differential mechanism and motor vehicle.If become
Fast utensil has motor, then power assembly system can realize the multiple drive modes of motor vehicle.It is motor-driven in electric running operation
Car is driven by the motor of speed changer.In with internal combustion engine operation, motor vehicle is driven by internal combustion engine.In combination drive operation, machine
Motor-car not only drove by internal combustion engine but also by the motor of speed changer.
" permanently connected " refers to existing connection all the time between two elements.So permanently connected element is all the time with its turn
Identical correlation rotation between speed.There can not possibly be switching device between the two elements permanently connected.Therefore, forever
Connection is different from changeable connection long.The connection that can not forever rotate against refers to existing connection all the time between two elements
And therefore its element connected has identical rotating speed all the time.
