Integrated gear assembly
An integrated gear assembly includes a conjoined carrier assembly coupling a reducing gear set to a differential gear set. This includes first, second and third coaxial sun gears. The first sun gear meshingly engages first gear elements of stepped pinion gears of the reducing gear set. The second sun gear meshingly engages third pinion gears of the differential gear set. The third sun gear meshingly engages fourth pinion gears of the differential gear set. The third pinion gears of the differential gear set axially overlap second gear elements of the stepped pinion gears of the reducing gear set. The fourth pinion gears of the differential gear set axially overlap the third pinion gears of the differential gear set.
Baffle for lubrication management in an axle assembly
A vehicle axle includes a housing defining a sump, a gear assembly and a baffle. The gear assembly includes a ring gear disposed within the housing. The ring gear is configured to pump fluid throughout the housing. A pinion gear is meshed with the ring gear. The baffle is disposed within the sump and connected to the housing. The baffle has a first part being configured to control fluid flow across the ring gear and a second part attached to the first part. The second part is configured to control fluid flow across the pinion gear.
Direct torque path differential having spiderless pinions
A differential is disclosed for use with a drivetrain of a mobile machine. The differential may have an input gear, a first side gear, a second side gear, and a side pinion disposed between and intermeshed with the first and second side gears. The differential may also have a carrier connected to the input gear and surrounding the first side gear, the second side gear, and the side pinion. The carrier may have a first orifice located in an annular wall at a base end of the side pinion, and a second orifice located in an axial wall. All lubrication passing through the first orifice may flow around an external surface of the side pinion.
Powertrain for a motor vehicle, differential planetary gear system for a powertrain, and motor vehicle comprising a powertrain
A powertrain for a motor vehicle, with a differential planetary gear system, which has at least one ring gear with ring gear toothing, at least one sun gear with sun gear toothing, planetary gears which engage with the ring gear toothing on one side and with the sun gear toothing on the other side, and a planetary gear carrier, on which the planetary gears are rotatably mounted. The ring gear toothing and the sun gear toothing have the same number of respective gear wheel teeth.
Two-speed drive module
A drive module that includes an electric motor, a differential assembly with a differential input member and a pair of differential output members, a multi-speed transmission assembly, which transmits rotary power between the electric motor and the differential input member, and a pair of axle shafts that are each coupled to an associated one of the differential output members for rotation therewith. The multi-speed transmission assembly and includes a housing, a two-speed planetary transmission stage, a plurality of clutches and a transmission output member that provides rotary power to the differential input member. The two-speed planetary transmission stage has an input sun gear, which is driven by the motor, and employs a set of planet gears having compound planet gears that provide a gear reduction between the sun gear and the transmission output member. The clutches are employed to control an overall reduction ratio.

Park lock for an automatic transmission
A park lock for an automatic transmission includes a primary actuator that is operable to move a primary rod such that the primary rod rotates a pawl and selectively meshes a tooth of the pawl with teeth of a park wheel. A secondary actuator is operable to move a secondary rod. A distal end portion of the secondary rod holds the tooth of the pawl in meshing with the teeth of the park wheel in a park configuration. The distal end portion of the secondary rod blocks the tooth of the pawl from meshing with the teeth of the park wheel in a drive configuration. A related automatic transmission is also provided.
Differential
A differential, including: a gear housing; an epicyclic housing which is mounted in the gear housing in a manner allowing rotation about a gear axis; a planet carrier arranged in the epicyclic housing in a manner allowing rotation; a first output sun gear; a second output sun gear; a planetary arrangement, accommodated in the planet carrier, coupling the output sun gears in a manner allowing opposite rotation; a brake device generating a bridging torque which places a load on relative rotation of the first and second output sun gears, according to a magnitude of an axial force applied to the brake device; and an actuating mechanism for the purpose of generating said axial force applied to the brake device. The actuating mechanism is designed in such a manner that the first bridging torque generated by the brake device increases as a rotary drive torque applied to the epicyclic housing increases.

Control system for hybrid vehicle
A control system for a hybrid vehicle configured to prevent a reduction in the purifying performance of the catalyst in a predetermined operating mode. An operating mode of the hybrid vehicle can be selected from a first hybrid vehicle mode, a second hybrid vehicle mode, and a fixed mode. A controller that is configured to restrict a shifting operation between the first hybrid vehicle mode and the second hybrid vehicle mode via the fixed mode, when the purifying device is being warmed or the purifying device has to be warmed.
