A turbomachine engine includes a fan assembly and a core engine comprising a turbine and an input shaft rotatable with the turbine is provided. A single-stage epicyclic gear assembly receives the input shaft at a first speed and drives an output shaft coupled to the fan assembly at a second speed. A sun gear rotates about a longitudinal centerline of the gear assembly and has a sun gear-mesh region along the longitudinal centerline of the gear assembly where the sun gear is configured to contact a plurality of planet gears. A ring gear-mesh region is provided along the longitudinal centerline of the gear assembly where a ring gear is configured to contact the plurality of planet gears. The sun gear-mesh region is axially offset from the ring gear-mesh region along the longitudinal centerline.

A freewheel has a first ring which has a first blocking contour on a first axial side and a second ring which is rotatable relative to the first ring and which has a second blocking contour on a second axial side pointing toward the first axial side of the first ring. Tiltable blocking bodies can be caused to engage into the first blocking contour and into the second blocking contour. A switching element tilts the blocking bodies. A displacement unit axially displaces the second blocking contour relative to the first ring between an active setting, which is axially approximated to the first ring, and an inactive setting, which is axially remote from the first ring and in which torque-transmitting blocking of the first ring with the second ring is prevented in any setting of the blocking bodies.

Systems and methods for controlling transmissions having CVTs are disclosed with multiple modes and gearing arrangements for range enhancements, where embodiments include synchronous shifting to allow the transmission to achieve a continuous range of transmission ratios, while minimizing “empty” cycling of the CVT during mode shifts. Embodiments provide for wide ratio range and performance and efficiency flexibility, while maximizing CVT usage through synchronous shifting.

A planetary gearbox includes a first planetary stage with a component, a sun gear, and a planet gear meshing with the sun gear via a toothing system, a second planetary stage, and a lubricant transfer device arranged between the first planetary stage and the second planetary stage. The lubricant transfer device includes a discharge component arranged in a co-rotating manner on a component of the second planetary stage, and a receiving component designed to receive lubricant and arranged in a co-rotating manner on the component of the first planetary stage. A lubricant conduit communicates with the lubricant transfer device and is configured to extend over an entire axial extent of a tooth engagement region of the sun gear of the first planetary stage radially within the toothing system of the sun gear with the planet gear of the first planetary stage.

The invention relates generally to compound planet gear arrangements for transmitting torque between two rotating shafts, by splitting the torque into several torque transmitting gear components. The gear arrangements may contain gear shifts arrangement and free-wheel arrangements. The invention also relates to gear wheel arrangements having enhanced torsional compliance capabilities, which gear wheel arrangements advantageously may be used in said compound planet gear arrangements and also at other applications such as at other over-determined systems or where intermittent loads and forces occur. According to one aspect, the invention relates to a gear wheel arrangement (700, 800, 900), comprising; a first part (710, 810, 910) which is arranged to be rotationally fixed to a shaft; a second part (720, 820, 920) which is rotatably connected to the first part and provided with gear teeth for meshing with an adjacent gear. The first and second parts are mechanically connected by means of at least one first elastically deformable member (750, 850, 950) which allows a limited relative rotation between the first and second part. The gear teeth (721, 821, 921) of the second part (710, 810, 910) are helical and the gear wheel arrangement is arranged to allow a limited relative axial displacement between the first part and the second part.

Provided are an electric vehicle transmission including an improved one-way clutch. An electric vehicle transmission includes a sun gear unit connected to a transmission motor, a plurality of planetary gear units connected to the sun gear unit, and a ring gear unit connected to the planetary gear units, and further includes a cage unit arranged to surround the plurality of planetary gear units at an inner side thereof, a housing unit arranged at an outer side of the cage unit and having a hollow therein, at least one guide unit arranged between the cage unit and the housing unit, and an adjustment unit configured to adjust a position of the cage unit with respect to the housing unit.

A commercial vehicle includes at least one driven axle, a service brake, at least one propulsion engine, and wheels. A parking brake function of the vehicle is achieved by a bistable locking means that acts on both wheels. A first and second multi-speed gearbox having respective first and second gear stages are each activated by an actuator and coupled to the wheels. The parking brake function is achieved at least in-part by concurrently activating the first and second gear stages. A computing device is configured to activate the bistable locking means when the commercial vehicle is at a standstill and configured to send a brake request via an electronic signal to an electronic brake control unit to activate the service brake.
