輪轂動平衡配重計算器
計算車輛輪胎所需的動平衡配重。輸入測得的不平衡量與輪圈直徑,以找出正確的夾片式或黏貼式配重。
結果
校正配重公式
校正質量由測得不平衡量與校正半徑(輪胎中心至配重安裝位置的距離)決定:
- m校正 — 所需配重(克)
- U — 測得不平衡量(g·mm)
- R — 校正半徑(mm)
由輪圈直徑計算校正半徑
校正半徑近似為輪圈直徑換算為毫米後的一半:
此假設配重安裝於輪圈邊緣(凸緣)。對於安裝位置更靠內的黏貼式配重,有效半徑可能較小。
標準配重遞增量
輪胎動平衡配重採用標準 5 g 遞增量。計算出的配重將四捨五入至最接近的可用規格:
| 標準配重(克) |
|---|
| 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 |
配重類型
| 類型 | 材料 | 典型用途 |
|---|---|---|
| 夾片式鋼質 | 鋼材 | 鋼製輪胎,部分帶凸緣的合金輪圈 |
| 夾片式鋅質 | 鋅合金 | 鋼製/合金輪胎,無鉛替代品 |
| 黏貼式鋼質 | 鋼材 | 合金輪胎,隱藏式安裝於輪轂內部 |
| 黏貼式鋅質 | 鋅合金 | 合金輪胎,無鉛,隱藏式安裝 |
| 鉛質夾片式 | 導程 | 舊式 / 經典車輛(正逐步淘汰) |
實務範例
已知: 測得之不平衡量 = 1500 g·mm,輪圈直徑 = 17″
R = 17 × 25.4 / 2 = 215.9 mm
m = 1500 / 215.9 = 6.95 g
最接近之標準配重: 5 g (向下取整)或 10 g (向上取整)
最佳匹配(最接近): 5 g
⚠️ 注意: 貼附於輪圈內側之黏貼式配重,其校正半徑略小於安裝於緣板之夾掛式配重。為求精準,請量測實際安裝半徑。本計算器以輪圈邊緣作為近似值。
Wheel balancing compensates for uneven mass distribution in a tire-wheel assembly. A balancing machine spins the wheel at high speed and uses sensors to measure the unbalance magnitude and angle at each correction plane.
Weights are then placed at specific locations on the rim to counteract the heavy spot. This reduces vibration transmitted to the steering wheel and vehicle body at highway speeds.
Clip-on weights attach to the outer rim flange using a spring-steel clip. They are mainly used on steel wheels and some OEM alloy wheels with suitable flanges.
Adhesive (stick-on) weights use a peel-and-stick tape backing and are placed on the inside of the rim barrel. They are preferred for alloy wheels because:
- No visible weights on the outside
- No risk of scratching or damaging the rim finish
- Better aesthetic appearance
For passenger cars, residual unbalance below 5 g per plane is generally acceptable. Most modern wheel balancing machines resolve to 1–5 g.
Unbalance above 10–15 g per plane usually causes noticeable steering vibration at highway speeds (80–120 km/h / 50–75 mph). Heavy trucks and commercial vehicles have higher tolerances due to larger tire mass.
A wheel can have two types of unbalance:
- Static unbalance — heavy spot in one plane, causes up-and-down vibration
- Dynamic (couple) unbalance — offset heavy spots in different planes, causes side-to-side wobble
Two-plane (dynamic) balancing corrects both components simultaneously. Single-plane correction only handles static unbalance and may leave a residual couple.
Static balancing corrects unbalance in one plane only. The wheel's center of gravity is moved back to the rotation axis. This is simpler but incomplete for wide wheels.
Dynamic balancing uses two correction planes (inner and outer) to eliminate both the force unbalance and the couple unbalance. This is the standard method for all modern passenger vehicles and provides the smoothest ride.
