An improved railway car axle has a generally hollow cylindrical elongated body. The axle includes a journal near either end adapted to receive a bearing, and a dust guard adjacent the journals. A wheel seat is adjacent the dust guard and is adapted to receive a railway wheel thereon. The axial center interior portion of the railway axle is generally hollow. The railway axle is comprised of a steel with specified alloy range, mechanical properties and is of specified internal and external dimensions to allow the axle to be formed in a forging operation and to be utilized in heavy haul railway freight car service.

Axle for rail vehicles, made of heat-treated material, wherein in all cylindrical parts (2a) and the transitional parts (2b) along the entire length (L) of the axle (1) surface the axle (1) surface is formed by a reinforced, inductively hardened layer (2) having of uniform depth from the axle (1) surface and this inductively hardened layer (2) continues with a transition layer (3) with a gradually decreasing gradient of reinforcing. Transition layer (3) depth is equal to at least 1.5 times of the depth of the inductively hardened layer (2).

A motorcycle wheel adapter includes a metal tube; a sprocket mounting plate joined to the metal tube near one end; a brake assembly mounting plate joined to the metal tube near another end; and a wheel mounting plate joined to the metal tube in between. The wheel mounting plate is closer to the brake assembly mounting plate than to the sprocket mounting plate. The tube has a first end, a second end, and a longitudinally formed bore. The sprocket mounting plate, the brake assembly mounting plate, and the wheel mounting plate have evenly spaced holes around their perimeters. A rear wheel assembly comprises a sprocket, a wheel, a brake drum, and the motorcycle wheel adapter. The motorcycle wheel adapter converts the motorcycle from a narrow, tube type, spoked motorcycle wheel to a more offroad-capable and reliable ATV style tire and wheel allows for more reliability, easier repairs, and more traction.
