A transmission includes a primary gear including primary teeth, each having a primary surface; a secondary gear including secondary teeth; an intermediate gear including intermediate teeth, each comprising a primary intermediate part having a primary intermediate surface and a secondary intermediate part having a secondary intermediate surface, where the primary intermediate part is axially offset from the secondary intermediate part. The intermediate gear is axially displaceable to an engaged position. The primary surface contacts the primary intermediate surface in a contact region and the secondary intermediate surface contacts one of the secondary teeth. In the engaged position, one primary tooth and one intermediate tooth form an overlap, radially inside the contact region, for preventing the intermediate gear from being displaced from the engaged position to a disengaged position.

Transmission, gearbox and vehicle

The disclosure relates to a powertrain for a vehicle, the powertrain including: a transmission, a propeller shaft and a differential gear, wherein the transmission comprises an output shaft which is drivingly connected or connectable to the propeller shaft, the propeller shaft is drivingly connected to the differential gear and the differential gear is configured to provide a driving torque to a respective half-shaft of a drive axle for driving the vehicle, the transmission further including: an input shaft configured to be drivingly connected to a power unit; a planetary gearset; a first gearset and a second gearset. The disclosure also relates to a vehicle.

Transmission, a powertrain and a vehicle

Transmission for a vehicle

A transmission for a vehicle includes a first input shaft, a second input shaft, a countershaft, a main shaft, and an output shaft, a first gear plane including a first input shaft gearwheel, a first main gearwheel, and a first countershaft gearwheel, and a second gear plane including a second input shaft gearwheel, a second main gearwheel, a second countershaft gearwheel, a first gear engaging device, a second gear engaging device, wherein the output shaft is drivingly connectable to the main shaft, and wherein the transmission is configured to only enable transfer of torque between the first input shaft and the output shaft via the main shaft, and to only enable transfer of torque between the second input shaft and the output shaft via the main shaft.

The invention relates to a vehicle powertrain, comprising:

Powertrain, a method for controlling a powertrain, and a vehicle

A transmission for a vehicle includes an input shaft, a planetary gearset comprising a sun gearwheel, one or more planet gearwheels, a planet gearwheel holder and a planet ring gearwheel, a first gearwheel, a second gearwheel, a third gearwheel, a fourth gearwheel and a fifth gearwheel, an output shaft, and at least two gear engaging devices which are configured to provide at least four selectable gear connections. The planet ring gearwheel is rotatably connected or connectable to the first gearwheel. A first gear engaging device is configured to be provided in a first state where it rotationally connects the second gearwheel to the fourth gearwheel and in a second state where it rotationally disconnects the second gearwheel from the fourth gearwheel. The third selectable gear connection is provided by at least setting the first gear engaging device in the first gear engaging device first state.

An electric machine comprising a rotor, a stator, and a fluid-based brake arrangement for said rotor, said fluid-based brake arrangement having a fluid circuit for transporting a brake fluid, said fluid circuit comprising a fluid channel arrangement having at least one radial fluid channel segment extending radially through a part of said rotor so as to allow for directing brake fluid from an inner radial rotor side to an outer radial rotor side, whereby, during rotation of said rotor about an axial centre axis, acceleration of brake fluid in said at least one radial fluid channel segment causes a reaction force exerting a braking torque on the rotor.

Electric machine for a vehicle

A transmission comprises a first input shaft, a second input shaft, an output shaft, and an intermediate shaft. A first input shaft gearwheel, a second input shaft gearwheel, a first intermediate shaft gearwheel, a second intermediate shaft gearwheel, a first output shaft gearwheel drivingly connected to the first input shaft gearwheel, a second output shaft gearwheel in meshing engagement with the first intermediate shaft gearwheel, and a third output shaft gearwheel in meshing engagement with the second intermediate shaft gearwheel, are provided. A first shifting device is selectively settable to: A second shifting device is selectively settable to:

Transmission, a powertrain, and a vehicle

A transmission provides nine forward gears from the first gear to the ninth gear, including a first and a second planetary gear set configured axially in series, each planetary gear set configured to provide a first and a second forward speed reduction and one direct speed with a one to one (1:1) speed ratio, the first forward speed reduction being larger than the second forward speed reduction, wherein each planetary gear set is individually shiftable between three forward speeds with different speed ratios. The transmission is configured to provide the first to third gears by utilizing the first speed reduction of the second set, the fourth to fifth gears by utilizing the first speed reduction of the first set, the sixth to seventh gears by utilizing the second speed reduction of the first set, and the eighth to ninth gears by utilizing the direct speed of the first set.
