Hub reduction gear and driveline for a wheeled vehicle and multi-shaft wheeled vehicle

Driveline for a multi shaft wheel supported vehicle with drive on wheels on several shafts, comprising:

• at least one driving motor,
• a transmission connected to the driving motor,
• an output shaft from the transmission, wherein each wheel shaft is co-ordinated to a differential with output left and right drive shaft and the differentials being mutually connected by means of a cardan shaft section, and
• a hub reduction gear in each driving wheel with a planetary gear unit integrated therein, each planetary gear unit comprising:
• a sun gear connected to a respective drive shaft,
• a carrier for planet gears, which mesh with the sun gear, and
• a ring gear surrounding the planet gears, said ring gear being in mesh with the planet gears,
• wherein the carrier and the ring gear of the planetary gear units on at least one side of the vehicle are configured to be connected to and disconnected from each of the respective driving wheel and a body-fixed part,
• wherein the carrier is fixedly connectable to the driving wheel of the vehicle by means of a first engagable and disengagable clutch and engagably and disengagably connected to the body-fixed part of the vehicle by means of a second engagable and disengagable clutch,
• wherein the ring gear is fixedly connectable to the driving wheel of the vehicle by means of a third engagable and disengagable clutch and engagably and disengagably connected to the body-fixed part of the vehicle by means of a fourth engagable and disengagable clutch,
• wherein the first and fourth clutches are arranged to be engaged when the second and third clutches are disengaged and vice versa, and
• wherein all clutches are electrically, pneumatically or hydraulically controllable between their engaged and disengaged positions.
