Assembly for lubricating a gearwheel of a transmission, a transmission and a vehicle

An assembly for lubricating a gearwheel of a transmission, the assembly comprising:

• a shaft arranged to rotate about a rotational axis extending in an axial direction,
• the gearwheel arranged rotationally fixed on the shaft, the gearwheel comprising a plurality of gear teeth arranged circumferentially around the gearwheel with respect to the rotational axis,
• a first ring member arranged coaxially and rotationally fixed on the shaft adjacent the gearwheel, wherein the first ring member has an axial end face comprising a circumferential portion which protrudes in the axial direction towards the gearwheel such that an inner peripheral surface is formed on the circumferential portion, wherein the inner peripheral surface of the circumferential portion, the axial end face of the first ring member, the gearwheel, and the shaft, define a space, and
• a lubricant distribution ring member for providing lubricant to gear valleys between respective adjacent gear teeth of the gearwheel, wherein the lubricant distribution ring member is arranged inside the space, and wherein at least one of the first ring member, the gearwheel and the lubricant distribution ring member is configured such that the lubricant distribution ring member is axially press-fitted between the gearwheel and the first ring member.
