橫拉桿剛度、輪胎的側偏剛度、轉向機剛度、轉向機阻尼、繞主銷當量阻尼、主銷后傾角、輪胎拖距是影響擺振的敏感性參數，適當調節某一參數可引起系統的負阻尼，使系統產生自激擺振；輪距、輪胎側向剛度、車輪上的不平衡質量、輪胎垂向剛度及主銷延長線與地面交點至車輪平面的距離對擺振的影響也較大，但不會使系統出現負阻尼；而橫拉桿阻尼、懸架阻尼與懸架剛度對擺振的影響很小。Establishing a close partnership with tianjin huashengchang gear company, we can produce the plane enveloping toroidal worm reducer with a high accuracy and a high productivity which has high efficiency in transmission and less noise and stable operation
