TH164089B - Rotating body shafts, rotating body structures, and vehicle wheels - Google Patents

Abstract

The purpose of the present invention is To provide a rotating body shaft, a rotating body structure and a vehicle wheel. Where adequate torsional strength is guaranteed while maintaining Costs to be low In the casting substrate state The peripheral surface of this rotating body shaft (3) has multiple protrusions; This rotary body shaft (3) is completely encapsulated with a cast piece of the main body. At the center of rotation of the main body a rotating body (2) and an external torsional moment is passed. Also, the specific gravity of the material of the rotating body (2) is less than the specific gravity of the material of the rotating body shaft (3) and the number of protrusions (5). Much is created on the external periphery of the rotating body shaft (3). In the preliminary state, the shape of the protrusion (5) has three segments from the peripheral to the peripheral, intrinsic part. The leading side has a domed shape, the middle is neck shape, and the base has a conical shape for those protrusions (5) that are 0.3 mm or more from the external surface. (3) the ratio of the overall cross-sectional area bounded by the contour always at the position of 0.3 mm in height and the surface area of the peripheral surface of the BODYCHAF. The rotary position (3) is 5 - 50%:

Claims (1)

1. Spinning shaft, which is encapsulated by the casting piece of the main body, rotates across the rotating shaft. And was positioned at the center of rotation of the main body The deck transmits the twisting moment. To the main body of the rotator, where the specific gravity of the material of the rotor shaft is greater than the specific gravity of the main body; Each filing has a shape, which is made up of three parts, which from the periphery. Outside to the periphery, inside is the fish section:
