SCOPE This SAE Recommended Practice establishes uniform engineering nome
6、nclature for the most common wheel constructions, and their components used on passenger cars, light trucks, and multipurpose vehicles. These wheel constructions are welded “Disc Wheels”, “Cast Wheels” and “Forged Wheels”. This nomenclature and the accompanying drawings are intended to define fundam

DEFINITIONS 3.1 Wheel A rotating load-carrying member supporting the tire and affixed to the hub. Disc Whe
11、els usually consist of two major components: (a) the rim, as shown in Figure 1; (b) the disc, as shown in Figure 2. The rim and wheel disc may be integral, permanently attached, or detachable. Cast Wheels or Forged Wheels typically have a one-piece construction, as shown in Figure 3. 3.1.1 Rim That
12、part of the wheel on which the tire is mounted and supported. (See Figure 1.) 3.1.2 Wheel Disc That part of the wheel which is the supporting member between the hub and the rim. (See Figure 2.)

Inset is the distance from the wheel attachment face to the center
17、plane of the rim. (See Figure 4.) FIGURE 4 - RIM TO DISC LOCATION 3.1.5 Zeroset Wheel A wheel so constructed that the center plane of the rim is coincident with the wheel attachment face. (See Figure 4.) 3.1.6 Outset Wheel A wheel so constructed that the center plane of the rim is located outboard o
18、f the wheel attachment face. Outset is the distance from the wheel attachment face to the center plane of the rim. (See Figure 4.) 3.2 Wheel Types 3.2.1 Disc Wheel A permanent combination of a rim and wheel disc. (See Figure 2.) SAE INTERNATIONAL J1982 MAY2016 Page 7 of 9 3.2.2 Cast Wheel A wheel fo
19、rmed by a casting, and subsequent machining process, (See Figure 3.) 3.2.3 Forged Wheel A wheel that has been forged from a billet and subsequently machined (as necessary) to create functional features for balance, tire mounting, balance weight retention and hub attachment. (See figure 3.) 3.3 Rim T

(See Figure 1.) 3.3.2 Two-Piece A rim with two pieces that are not permanently attached. 3.3.3 Average Radial Runout The average radial run-out of the inner and outer bead seats measured simultaneous
21、ly. Measurements are taken adjacent to the R3 radii. 3.3.4 Average Lateral Runout The average lateral runout of the inner and outer flanges measured simultaneously. Measurements are taken adjacent to the R3 radii. 3.4 Rim Nomenclature (See Figures 1. and 3.) 3.4.1 Flange That part of the rim which p
22、rovides lateral support to the tire and a means for attaching balance weights and decorative trim components. 3.4.2 Bead Seat That part of the rim which provides radial support to the tire and air pressure seal for tubeless tires. 3.4.3 Well That part of the rim so located with sufficient depth and
23、width to enable the tire beads to be mounted and dismounted over the mounting side rim flange. 3.4.4 Valve Hole The hole or slot in the rim which accommodates the valve for tire inflation. 3.4.5 Balance Weight Retention Groove A circumferential groove located on the rim flanges to improve balance we
