  • Publication number: 20230243125
    Abstract: The present invention relates to a control unit for a vehicle. The vehicle includes a wheel axle fluid circuit adapted to feed wheel axle fluid to one or more wheel axles of the vehicle. The vehicle further includes a propulsion assembly adapted to propel the vehicle. The control unit is adapted to, on the basis of at least the following: information indicative of the propulsion assembly being inactive, information indicative of an expected time range until an expected operation start time of the vehicle, and information associated with a temperature of the wheel axle fluid, determine whether or not a conditioning procedure, during which the temperature of the wheel axle fluid is increased as compared to a present temperature of the wheel axle fluid, should be initiated for the wheel axle fluid.

  • Patent number: 10975548
    Abstract: A wheel loader front unit includes a frame for a wheel loader, the frame including an upper joint element and a lower joint element for connecting the frame to a rear unit of the wheel loader, and for transferring loads between the frame and the rear unit, the frame including a lift arm mounting point for a pivot connection of the frame and a lift arm for lifting an implement of the wheel loader. The upper and lower joint elements are arranged so that a first of the upper and lower joint elements, during use of the wheel loader, transfers a larger vertical load than a second of the upper and lower joint elements, and the lift arm mounting point is located closer to the first of the upper and lower joint elements than to the second of the upper and lower joint elements.
