MOTOR VEHICLE TRANSMISSIONS, IN PARTICULAR ELECTRIC VEHICLE TRANSMISSIONS
The invention relates to a motor vehicle transmission (6) comprising a drive input shaft (9), a drive output shaft (10), a first planetary gearset (P1), a second planetary gearset (P2), and a third planetary gearset (P3), where the drive input shaft (9) is provided for coupling to an electric machine (5). Furthermore, at least functionally a first shifting element (A), a second shifting element (B), and a third shifting element (C) are provided. In addition, the invention relates to a drive unit (4), a drive axle (3), and an electric vehicle.
VEHICLE ELECTRIC DRIVE AXLE
An electric drive axle in a vehicle is provided. The electric drive axle includes, in one example, an electric motor-generator, a gearbox, and a differential. The gearbox comprises a planetary gear set that includes a sun gear configured to rotate on a sun gear shaft directly coupled to a rotor of the electric motor-generator and an intermediate shaft that includes an idler gear rotationally coupled to a pinion gear that is rotationally coupled to the carrier.
Actuator arrangement and transmission arrangement
An actuator assembly for actuating two switching units in the driveline of a motor vehicle comprises a housing; an actuator drive; a switching rod arranged in the housing and axially movable by the actuator drive in three positions; a first switching element and a second switching element axially movably arranged on the switching rod; a spring element which biases the first switching element against a first shaft stop and the second switching element against a second shaft stop; a first housing stop against which the first switching element can be axially supported; and a second housing stop against which the second switching element can be axially supported. A transmission assembly can include such an actuator assembly.
PROPULSION SYSTEM FOR AN ELECTRIC VEHICLE
A propulsion system for an electric vehicle includes an assembly of four electric propulsion machines each having a stator and a rotor having an output shaft that is movable in rotation about an axis. Also includes is a common gearwheel that is kinematically connected to the n output shafts and that is able to receive the torque provided by the electric machines so as to form a first speed reducer, and primary gearwheels able to be driven by the common gearwheel. An intermediate shaft is able to be driven by intermediate gearwheels, each primary gearwheel being kinematically connected to a corresponding intermediate gearwheel so as to form a pair of gears with which a second speed reducer is associated, and a secondary shaft that is able to drive the vehicle and that has a secondary gearwheel kinematically connected to the intermediate shaft so as to form a third speed reducer.
DRIVE SYSTEM FOR AN ELECTRIC VEHICLE
Drive system for an electric vehicle including a first sub-assembly of electric machines kinematically connected to a first common gear, and a second sub-assembly of electric machines kinematically connected to a second common gear. A first set of gear trains is kinematically connecting the first sub-assembly to a secondary shaft capable of driving the driving wheels of the vehicle, wherein a first selective coupling system is arranged to select a first gear train or a second gear train from a neutral position during a gear change phase. A second sub-assembly kinematically connects the second common gear to the secondary shaft. The second sub-assembly of electric machines is controlled so as to supply additional torque making it possible to compensate for the loss of torque resulting from the uncoupling of the first sub-assembly inherent in the gear change.
ELECTRIC POWERTRAIN FOR A VEHICLE
an electric powertrain integrated into a vehicle axle. Such electric axle (or “E-axle”) is a front or rear axle that includes an axle body (or “housing”) adapted to receive a powertrain, which is arranged to provide torque to the wheels of the axle. The “E-Axle” is a compact and economical electric drive solution for battery electric vehicles, fuel cells and hybrid applications. The electric motor(s), electronics and transmission are combined in a compact unit that directly drives the wheels provided at the longitudinal ends of the axle.
Axle assembly having an interaxle differential unit
An axle assembly having an interaxle differential unit. The interaxle differential unit includes first and second side gears and a gear nest but does not have a case. The gear nest includes a spider having at least one spider shaft, a pinion gear that is rotatably disposed on the spider shaft, and a pinion gear retainer that is fastened to the spider shaft to retain the pinion gear.
ELECTRIC DRIVE AXLE
The present document relates to an electric drive axle comprising an electric motor, a first planetary gear set, a second planetary gear set, and a differential assembly. The electric motor is drivingly connected or drivingly connectable to the differential assembly via the first planetary gear set and via the second planetary gear set.
Skew limiter for a Toric-drive CVT
In part, skew limiter for a toric-drive CVT embodiments are disclosed. A skew limiter may include a shaped piece that limits the skew angle to a known angle notwithstanding the tilt angle of the rollers.
Drive Arrangement of a Working Machine to be Driven with a Variably Adjustable Speed and Method for Operating the Drive Arrangement
A drive arrangement of a working machine to be driven at a variably adjustable speed includes a differential gear, a first drive unit coupled to a first element of the differential gear, a working machine coupled to a second element of the differential gear, and a second drive unit coupled to a third element of the differential gear. The speed of the second drive unit can be superimposed on a speed dependent on the speed of the first drive unit, whereby the first or second drive unit can be driven at a variably adjustable speed. The drive arrangement includes an auxiliary gear stage and a switching element interacting with the auxiliary gear stage, wherein, when the switching element is closed, the auxiliary gear stage is load-transmitting and the speeds of the first and second drive units are coupled as a function of at least one transmission ratio of the auxiliary gear stage, and when the switching element is open, the auxiliary gear stage is load-free and the speeds of the first and second drive units are decoupled.
