An assembly having an electrical machine and a power electronics unit for use in a vehicle includes a housing part of the electrical machine connectable with a housing part of the power electronics unit at a seam between the two parts. Electrical pressure contacts are located in the vicinity of the seam between the two parts. Each pressure contact has one contact point located on the power electronics unit and one contact point located on the electrical machine. At least one contact point of a pressure contact is spring-loaded toward the other contact point of the same pressure contact.

An energy storing brake for a vehicle, such as an industrial truck, includes a rotating brake rotor (5) and a non-rotating braking body (3) that can be moved relative to the brake rotor (5). The braking body (3) can be pressed by an energy storing device (4), preferably realized in the form of a spring, against the brake rotor (5), and can be detached from the brake rotor (5) by a brake lifter against the force of the energy storing mechanism (4). A hydraulic cylinder (8) can be pressurized as required, by which a supplemental force in the same direction as the force of the energy storing mechanism (4) can be exerted on the braking body (3). The hydraulic cylinder (8) can be pressurized as a function of the actuation of a brake control mechanism, preferably of a brake pedal, by an operator. The sum of the forces that can be exerted on the braking body (3) by the energy storing mechanism (4) and by the hydraulic cylinder (8) is quantitatively greater than the force that can be exerted on the braking body (3) by the brake lifter.

An electrical machine with a stator and a rotor rotatable about an axis of rotation and having no bearing elements rotatably mounting the rotor relative to the stator or for defining the axis of rotation of the rotor is provided with means for releasably securing the rotor in position relative to the stator. The rotor can be secured relative to the stator in the axial and radial directions. Rotation of the rotor relative to the stator can also be prevented.
