An unsprung power supply apparatus is provided for an in-wheel motor vehicle. The unsprung power supply apparatus includes a steering knuckle, an in-wheel motor and a third link. The steering knuckle is configured to turn and steer a tire of the in-wheel motor vehicle. A virtual kingpin axis is an axis passing through a knuckle side coupling point at which the third link couples with the steering knuckle. In the unsprung power supply apparatus, a power supply cable connects the in-wheel motor and a power supply unit with a part of the power supply cable on a vehicle body side being fixed to the third link.

A drivable torsion beam axle (2) with a transverse profiled element and trailing arms (1) connected, at each end, to the profiled element is described, within which, at least in some areas, a drive-train (7) is arranged in each case and by which the torsion beam axle (2) can be connected to a vehicle body. The trailing arms (1) are, in each case, made as two-component housing castings with a housing plane of division extending in the longitudinal direction.

A trailing arm device (1) of a drivable torsion beam axle (2) is described. The trailing arm device (1) has a housing (5) in which a drive-train (8) can be arranged and is connected to a trailing arm (4). The housing (5), as fitted into position within a vehicle, has a sidewall (11) formed integrally with a central housing region (9) on a side facing toward a wheel. The sidewall delimits a housing interior space (10) that accommodates, at least partially, the drive-train (8). On the side facing away from the wheel, the housing interior space (10) is delimited by at least one cover element (14) that can be detachably connected to the central housing region (9).

An in-wheel motor drive unit (11) includes: a motor portion (11A) that is placed on one side in the direction of the axis of the in-wheel motor drive unit; a wheel hub portion (11C) that is placed on the other side in the direction of the axis of the in-wheel motor drive unit; a speed reduction portion (11B) that is placed between the motor portion and the wheel hub portion and that reduces the speed of output rotation of the motor portion to transmit the resultant output rotation to the wheel hub portion; and a first arm portion (34) that is formed integrally with a speed reduction portion casing (33) forming the outer shape of the speed reduction portion, that projects in a direction perpendicular to the axis from the speed reduction portion casing, and that has its tip end pivotally coupled to a vehicle body-side member.

A wheel suspension for a wheel of an axle of a motor vehicle. A wheel hub, which is rotatably mounted in a wheel carrier, can be driven by an electric drive engine. The wheel carrier is rotatably mounted by at least one link about a pivot axis on the vehicle body. The electric drive engine and the link are rigidly connected to one another.

An electric drive system including: a rotary motor system including a hub assembly, a first rotating assembly, a second rotating assembly, and a third rotating assembly, wherein the hub assembly defines a rotational axis about which the first rotating assembly, the second rotating assembly, and the third rotating assembly are coaxially aligned and are capable of independent rotational movement independent of each other; a multi-bar linkage mechanism connected to each of the first and third rotating assemblies and connected to the hub assembly and constraining movement of the hub assembly so that the rotational axis of the hub assembly moves along a defined path that is in a transverse direction relative to the rotational axis and wherein the multi-bar linkage mechanism causes the rotational axis of the hub assembly to translate along the defined path in response to relative rotation of the first rotating assembly and the third rotating assembly with respect to each other.
