Abstract: A vehicle wheel drive device includes: a rotary electric machine that is received on a radially inner side of a vehicle wheel shaped in a cylindrical tubular form and is configured to rotate the vehicle wheel; and a brake device that includes a brake disc and a brake caliper. The brake device is configured to generate a braking force relative to the vehicle wheel. The rotary electric machine includes a rotor and a stator which are opposed to each other in a radial direction. A hollow space is formed on a radially inner side of a magnetic circuit unit that is formed by the rotor and the stator. The brake device is placed in the hollow space in a state where the brake caliper is fixed to an axial end surface of the stator which faces in an axial direction, and the brake disc is rotatable integrally with the rotor.

Abstract: A brake element for a motor vehicle, having a base body that is planar at least in areas, to the planar sides of which at least two build-up layers are applied in each case, at least in areas. The build-up layers form a surface which, in the mounted state of the brake element on the motor vehicle, is used as a friction surface for a brake pad. A first build-up layer is present that adjoins the base body, and a second build-up layer is applied to the first build-up layer. The second build-up layer is made of a composite of an iron alloy matrix with intercalated tungsten carbide particles or with intercalated titanium carbide particles. At least the first build-up layer is an iron alloy that is alloyed at least with molybdenum in a range of 3 to 20 weight percent.

Abstract: In one aspect, a wheel hub apparatus including a wheel hub that is rotatable about a central axis and has a unitary, one-piece construction. The wheel hub apparatus further includes a circular brake element having a unitary, one-piece construction and extending about the wheel hub. The wheel hub and the circular brake element include engaged portions securing the wheel hub and the circular brake element together. The engaged portions of the wheel hub and the circular brake element fix the circular brake element against axial movement along the wheel hub. In this manner, the engaged portions of the wheel hub and the circular brake element provide a mechanical joint that connects the wheel hub and the circular brake element using the material of the wheel hub and the circular brake element.

A side wall section (17) of the brake hub (3) has a plurality of radially oriented deformations (5). A contact surface (7) extending in the radial direction is formed by these deformations (5), and a rotationally fixed connection (8) is established by the contact surface (7) between the friction ring (2) and the brake hub (3). A ratio Da/Di formed from the outer diameter Da of a side wall section (17) of the brake hub (3) and an inner diameter Di of the friction ring (2) is at most 1.01.

Abstract: A brake disk defines an annular shape having a radially inner side and a radially outer side. The brake disk includes: a radially outer braking surface, the braking surface having a maximum operating temperature; a fusible material section radially inward from and connected to the braking surface. The fusible material has a maximum operating temperature, the fusible material section suitable for transmitting torque between the braking surface and a shaft. The maximum operating temperature of the braking surface is higher than the maximum operating temperature of the fusible material section. When the temperature of the fusible material section raises above the maximum operating temperature of the fusible material section, the fusible material section is configured to no longer transmit torque between the braking surface and the shaft.
