Description

Include the dynamic of this speed changer for the speed changer of motor vehicle and for motor vehicle Power assembly system
Technical field
A kind of power for including this speed changer the present invention relates to speed changer for motor vehicle and for motor vehicle Assembly system.Speed changer refers in particular to multiple-speed gear-box herein, can preferably automatically be switched by switching device wherein multiple Gear, the fixed drive ratio i.e. between two axles of speed changer.Switching device is, for example, clutch or brake herein.It is this Speed changer is mainly used in motor vehicle, to make the rotating speed of driver element and torque output characteristic adaptation vehicle in a suitable manner Running resistance.
Background technology
The A1 of patent document DE 10162884 disclose a kind of multistage speed transmission, and it includes setting in the housing at least One drive shaft and driven shaft, two single file carrier planetary gearsets, the jackshaft level for defining fixed input gearratio, extremely Few seven rotatable axles and five switching devices.Drive device coaxially can be set in jackshaft level herein.Drive device and Output device may be provided on the same side of housing, and unique specifically disclosed implementation exemplifies drive device and output device in shell Body phase toss about on arrangement.This arrangement is particularly suitable to be used for the car with the power assembly system parallel to travel direction orientation .
Patent US 5429557A describe a kind of multistage including jackshaft level and two planetary gearsets being arranged concentrically Automatic transmission.Planetary gearsets are arranged at this in common plane, on every side of the plane respectively among setting One spur gear group of axle level.But the axial arrangement of speed changer is based on this arrangement and increased.
The content of the invention
The task of the present invention be to improve it is well known in the prior art, for being set transverse to motor-driven vehicle going direction Power assembly system motor vehicle in multiple-speed gear-box, to realize especially short axial arrangement length.
The task solves by the feature of claim 1.Advantageous scheme is by dependent claims, specification and attached Figure provides.
Speed changer includes drive shaft, driven shaft, the first and second spur gear groups, the planetary gearsets with total of four axle System, five switching devices and housing.Planetary gearsets system is axially parallel to drive shaft and coaxially in driven shaft herein Set.First and second spur gear groups have mutually different gearratio.
Four axles of planetary gearsets system are referred to as first axle, the second axle, the 3rd axle and the 4th axle, and its rotating speed is by the First, second, third, the name order of the 4th axle linearly increases, reduces or equal.In other words, the rotating speed of first axle is less than or equal to The rotating speed of second axle.The rotating speed of second axle is less than or equal to the rotating speed of the 3rd axle again.The rotating speed of 3rd axle is less than or equal to the 4th axle Rotating speed.The order is also reversible, therefore the 4th axle has minimum speed, and the rotating speed of first axle is more than or equal to more than the 4th The rotating speed of axle.Linear relationship all the time be present between the rotating speed of all four axles.The one or more of rotating speed of four axles can also have There are negative value or null value.Therefore rotating speed order is related to the tachometer value with symbol, rather than its absolute value all the time.When two of four axles When being connected to each other, this four axles have identical rotating speed.Therefore planetary gearsets system is primarily characterized in its kinematics, and Its non-structure.Driven shaft herein with it is permanently connected by the 3rd axle of rotating speed order.
This planetary gearsets system is formed by the dual coupling of two single planetary gear groups.The example of this respect is institute The Ravigneaux-Satz or Simpson-Satz of meaning.
It will can be fixed into by the first switching device of closure by the second axle of rotating speed order non-rotary.Pass through closure second First axle by rotating speed order can be fixed into non-rotary by switching device.By close the 3rd switching device can in drive shaft and Connected by being established between the 4th axle of rotating speed order via the effect of the second spur gear group guiding.By closing the 4th switching device It can be connected in drive shaft and by being established between the first axle of rotating speed order via the effect of the first spur gear group guiding.Pass through closure 5th switching device can be in drive shaft and the effect guided by being established between the second axle of rotating speed order via the second spur gear group Connection.
