Abstract: A suspension for a steerable driving wheel in a vehicle, in which a wheel supported by a wheel carrier rotatable around a steering axis is driven by a drive shaft and braked by a brake caliper, includes a hub and a brake disk. The hub has a supported portion rotatably supported by the wheel carrier through a bearing and is unrotatably connected to the drive shaft. The hub attaches the wheel to a portion located more laterally outward of a vehicle body than the supported portion. On the other hand, the brake disk for generating a braking force in cooperation with the brake caliper is provided on the hub and disposed more laterally inward of the vehicle body than said supported portion.

Abstract: An aluminium alloy made of consolidated rapid-quenched aluminium alloy powder by using an improved metallurgical method basically comprises, by weight percent, less than 30% silicone, less than 8% iron, less than 7% copper and less than 0.2% oxygen, the balance being substantially aluminium. The consolidated rapid-quenched aluminium alloy powder has features that it contains less than 0.2% oxygen, and the material made from the rapid-quenched aluminium alloy powder has a high limit compressibility factor, rate of reduction and tensile strength. Thus the aluminium alloy material obtained is suitable for structural members such as pistons for internal combustion engines.
