Abstract: The vehicle power device includes: a wheel bearing; and an electric motor including a stator and a rotor. The vehicle power device includes a rotor casing that is a cover member covering the electric motor and a part of the wheel bearing, the part being located on an inboard side with respect to the hub flange, such that a separated space is defined inside the cover member. A seal member configured to prevent entry of moisture from a press-fitting part where a hub bolt is press-fitted into a bolt hole provided in the hub flange is disposed near the press-fitting part. The hub flange is formed with an annular groove coaxial with the hub bolt in an area where a head of the hub bolt comes into contact with an inboard-side surface of the hub flange, and the seal member having a ring shape is disposed in the annular groove.

Abstract: Provided is a wheel bearing apparatus with a generator that can have a simplified structure to reduce costs and is capable of preventing electrolytic corrosion. The wheel bearing apparatus with a generator includes a wheel bearing and a generator. The generator includes a stator attached to a fixed wheel and a motor rotor attached to a rotating wheel and is of an outer-rotor type in which the stator is located on an outer periphery of the wheel bearing, and the motor rotor is located radially outside of the stator. The wheel bearing apparatus with the generator further includes at least one conducting unit that conducts a current between the fixed wheel and the rotating wheel.

Abstract: Provided is a device for determining a wheel fastening state that allows a wheel fastening state to be monitored during running. The device includes a sensor unit (3) that is attachable to and detachable from a wheel fastening part, an information terminal (4) that is an in-vehicle device (4A) or a portable terminal (4B), and a server (30). The terminal (4) includes a measurement instruction module (23) to read vehicle state data from a control and communication system (5) of a vehicle and send an instruction for to measurement to the sensor unit (3) at determined timing. The server (30) includes a first information processing module (32) configured to determine an abnormality of a fastening state of the wheel fastening part by comparing the measurement data with accumulated data that is measured under the same condition and stored in the past.

Abstract: An auxiliary power unit equipped wheel support bearing assembly is provided which includes a wheel support bearing assembly and an auxiliary power unit. The auxiliary power unit is of a direct drive design that includes a stator mounted to a stationary ring of the wheel support bearing assembly and a motor rotor mounted to a rotational ring of the wheel support bearing assembly. An entirety of the auxiliary power unit is sized to extend less than an outer peripheral segment of a brake rotor, with the outer peripheral segment defining an area against which a brake caliper is intended to be pushed. The auxiliary power unit is, with respect to an axial direction, sized to be situated between a hub flange of the wheel support bearing assembly and a mounting face of the wheel support bearing assembly for mounting to a vehicle body of a vehicle.
