Abstract: A device lubricates a connecting rod bearing on a crankshaft of an internal combustion engine. The device has a piston having an internal piston cooling fluid channel, and an outlet channel in fluid communication with the fluid channel. The device has a connecting rod, which is connected to the piston in an articulated, in particular pivotable, manner, and has a large connecting rod eye and a connecting channel. The large connecting rod eye is formed for receiving the connecting rod bearing. The connecting channel forms a fluid connection between the outlet channel and the large connecting rod eye so that a fluid, in particular a cooling lubricating fluid (e.g. oil), can be fed, or is fed, from the fluid channel to the large connecting rod eye via the outlet channel and the connecting channel. The connecting rod bearing can be lubricated by cooling oil from the fluid channel of the piston.

Abstract: A device lubricates a big-end bearing on a crankshaft of an internal combustion engine. The device includes a piston with a fluid channel and an outlet channel fluidically connected thereto, and a connecting rod. The connecting rod has a small connecting rod eye, a large connecting rod eye and a connecting channel. The small connecting rod eye is fluidically connected to the outlet channel.

Abstract: The invention relates to an arrangement for the drive mounting, in particular for a motor vehicle, preferentially a utility vehicle. The arrangement comprises a supporting structure, in particular a cross member structure. The arrangement comprises an, in particular electric, drive unit, which is attached to the supporting structure in a 3-point mounting on an underside and/or from below.
