Disclosed is a corner module apparatus for a vehicle. The corner module includes a knuckle coupled to a wheel bearing rotatably supporting a wheel, a drive motor, configured to generate a drive power, spaced a distance away from the wheel, a transfer shaft, disposed between the wheel and the drive motor, configured to transfer the drive power generated from the drive motor, a suspension connected to the knuckle and configured to absorb shock transferred from a road surface, and a steering system configured to support the drive motor and the suspension and to adjust a steering wheel of the wheel.

coating film having excellent adhesion, even without the presence of a chemical conversion film treatment out as an undercoat and a metal automotive part having the coating film.

A powder is deposited by powder-coating onto the surface of a metal automotive part that has been quenched after simultaneously forging, and tempering the metal automotive part and bake-hardening the deposited powder to form a skin film on the surface of the metal automotive part. The surface of the metal automotive part before the powder is powder-coated thereon is a work-hardened material surface that has been not been subjected to a chemical conversion filming treatment.

A constant velocity universal joint includes outer and inner joint members that transmit torque while allowing angular displacement via balls, a power transmission shaft connected to the inner joint member in a torque transmittable manner, and a detachable mechanism between the inner joint member and the power transmission shaft to detach the power transmission shaft from the inner joint member. The detachable mechanism includes a cylindrical member externally fit onto the power transmission shaft, spheres movable in a radial direction in the cylindrical member, and an annular member movable in an axial direction on an outer periphery of the cylindrical member. Locking claws are provided at an end of an inner joint member side of the annular member, and a locking groove is provided at an end of an annular member side of the inner joint member. The locking claws are fitted into the locking groove.

A forging apparatus includes an ironing mechanism and a phase alignment mechanism. The ironing mechanism includes: a punch set, which is fitted into a cylindrical portion of a pre-processing material to be formed into the outer joint member, and is radially expandable and contractible, the cylindrical portion having grooves formed in an inner peripheral surface thereof; and a die having a hole into which the cylindrical portion is press-fitted. The phase alignment mechanism is configured to align phases of the grooves in the inner peripheral surface of the pre-processing material and phases of track groove portion forming surfaces of the punch set with each other before the pre-processing material is fitted to the punch set.

A wheel bearing assembly is disclosed herein. The assembly includes a joint element having a first spline portion defined on an axial surface and a nose. An inner ring is provided that includes a through hole configured to receive at least a portion of the joint element and an abutment flange defined within the through hole. The inner ring includes a second spline portion configured to matingly engage with the first spline, and the nose of the joint element is configured to extend axially within the abutment flange. A connection assembly is configured to connect the inner ring and the joint element, and a portion of the connection assembly abuts a first axial end of the abutment flange.

A fixed ball type joint for a vehicle, which reduces the friction between a cage and an outer race and friction between the cage and an inner race by changing shapes of an inner spherical diameter of the outer race and an outer spherical diameter of the inner race. The fixed ball type joint for a vehicle includes an inner race, an outer race installed at the outside of the inner race, a plurality of balls for transmitting rotational power of the inner race to the outer race, and a cage for supporting the balls. A first inner spherical radius of the outer race is set to be smaller than a second inner spherical radius of the outer race. A first outer spherical radius of the inner race is set to be larger than a second outer spherical radius of the inner race.

A wheel-end disconnect assembly for translating rotational torque between an output shaft and a wheel hub of a vehicle driveline. A knuckle bracket at least partially supports the wheel hub. A clutch is operatively attached to the knuckle bracket, is disposed in selective torque translating relationship between the output shaft and the wheel hub, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the wheel hub, and a disengaged configuration wherein torque is interrupted. An electromagnetic actuator is provided and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the wheel hub.
