Abstract: The present invention relates to a counter-blade, in particular, for a wood chipper, for producing wood chips, comprising at least one cutting edge made of a hard material, and a support surface leading to the cutting edge. According to the present invention, the cutting edge is made up of a plurality of hard material elements that are arranged next to one another along the cutting edge on a main member. This results in a counter-blade having a long service life.

Abstract: A drive apparatus (1) for a motor vehicle has a hollow portal axle (2) that accommodates two electrical machines (4). Wheels (12) are mounted rotatably at opposite ends of the portal axle (2) and can be driven by the electrical machine (4) associated with the respective wheel. A step-down gear mechanism (8, 9) is arranged between each electrical machine (4) and the respective wheel (12) and a separate connection from the respective wheel to the step-down gear mechanism, permits the wheel to be mounted in a non-rigid manner. The respective step-down gear mechanism (8, 9) is connected to the respective wheel (12) by a cardan shaft (10).

Abstract: A chassis (1) for a motor vehicle has an electrical axle (2) with two electrical machines (4) for respectively driving two wheels (6). The chassis (1) also has a step-down gear mechanism (10, 11) arranged between the respective electrical machine and the associated wheel. Each step-down gear mechanism is connected to the respective wheel by a cardan shaft. The respective rotation axes (5, 5) of the two electrical machines are arranged parallel and next to one another. The chassis enables each wheel to be mounted in a non-rigid manner and permits the overall length of the electrical machines to be varied on account of the arrangement of the rotation axes of the electrical machines.

Abstract: A method for operation of a hybrid vehicle is provided. The hybrid vehicle has a first drive apparatus for driving the wheels on a first axle by an internal combustion engine, a second drive apparatus having two electrical machines for driving the wheels on a second axle, and at least one electrical energy store that can be discharged when an electrical machine is being operated as a motor and can be charged when an electrical machine is being operated as a generator. The method includes operating at least one driver-operated control for causing at least one of the electrical machines to output additional electrical drive torque to the axle that is not driven by the internal combustion engine.
