发明名称 DEVICE INCLUDING AN ELECTRIC MACHINE WITH A LIGHTWEIGHT DESIGN
摘要 An active part (4) of an electric machine (2) is connected to a supporting body (5) via a connecting structure and is fixed relative to the supporting body (5). A rotor (4′) of the electric machine interacts electromagnetically with a stator core (4″) and is mounted rotatably relative to the stator core (4″) so that the rotor (4′) is rotatable about an axis of rotation (8). The connecting structure comprises at least one hub (9), a supporting ring (12) and first and second struts (15, 19). The hub (9) surrounds the axis of rotation (8) and extends in the axial direction from an upper hub end (10) to a lower hub end (11). The hub (9) adjoins, with the upper hub end (10), the supporting body (5) and is fastened there to the supporting body (5). The supporting ring (12), on the outer side (13) thereof, adjoins the active part (4) and is connected to the active part (4). The first struts (15) extend in a radial plane (16) radially outwards from the lower hub end (11) to the supporting ring (12). The first struts (15) merge with the hub (9) in a respective radially inner transition region (17) and with the supporting ring (12) in a respective radially outer transition region (18). The second struts (19) extend from the upper hub end (10) to the supporting ring (12). In relation to the radial plane (16), the radially inner transition region (17) and the radially outer transition region (18) of a respective first strut (15) each form an angle (a) with the axis of rotation (8).

主权项 1. A device, comprising: a support body; and an electric machine, an active part of the electric machine being connected to the support body, and fixed relative to the support body, via a connecting structure, wherein the electric machine comprises a rotor that electromagnetically interacts with a stator pack and is mounted so as to be rotatable relative to the stator pack, such that the rotor is rotatable about an axis of rotation, wherein the connecting structure comprises at least a hub, a support ring, first struts, and second struts, wherein the hub surrounds the axis of rotation and extends, as viewed in a direction of the axis of rotation, from an upper hub end to a lower hub end, wherein the hub, via the upper hub end, adjoins the support body and is fastened to the support body, wherein the support ring, at a radially external outer side, adjoins the active part and is connected to the active part, wherein the first struts extend from the lower hub end radially outward to the support ring in a radial plane orthogonal to the axis of rotation, wherein the first struts transition, in a respective radially inner first transition region, into the hub and transition, in a respective radially outer first transition region, into the support ring, wherein the second struts extend from the upper hub end to the support ring, wherein, in relation to the radial plane, the radially inner first transition region and the radially outer first transition region of a respective first strut form in each case a first angle with the axis of rotation.
