tanabe避震, 轉向過多??? (15分)

本來呢條問題咁複雜唔係咁有心機答, 但因為樓上嗰位朋友可能唔小心答錯嘢, 所以想講解一吓

車係郁得嘅嘢, 所有郁得嘅嘢, 唔理轉左轉右行前行後加速減速, 都會牽涉到重心轉移.

轉向過多 (Oversteer, 甩尾), 即係前輪嘅抓地力比後輪多; 相反, 轉向過少 (Understeer, 推頭) 就係後輪嘅抓地力比前輪多, 轉唔到彎.

而家幻想吓你轉緊個左彎, 喺彎心踩 brake. 重心轉移, 由車尾轉向車頭, 車頭向下壓.

如果車頭彈弓太軟, 車尾彈弓過硬, 好自然個車頭就會 dup晒落去, 車尾就會兀起, 即係車頭重量壓喺前輪, 令到 traction 加大; 相反, 車尾升起咗, 向尾輪胎施壓少咗, traction 就低

後果會點, 我諗如果你仍然好專心去 imagine 呢架轉緊左嘅車的話, 就知道呢架車右後角會開始向外犀出去, 甩尾...

所以, 要架車轉向多D, 可以將車尾彈弓提升硬度嘅比率多過前面; 如果要轉向少D, 就將車頭彈弓提升硬度嘅比率多過後面.

但就算改車嘅避震coilover 都好少改到架車嘅操控咁危險. 呢條 coilover 拆箱時已經裝好可以上車嗎? 定係仲要鋪頭自己裝? 如果係後者, 好可能係前後彈弓調轉咗.

你亦都可以 check 吓條輪胎, 會唔會後面嗰兩條胎磨損嚴重過前面 (前面胎 traction 多過後面). 如果係, 試吓將前後胎對調, 睇吓有冇改善.

如果條 coilover 可以調校, 應該將車頭校硬D, 車尾校軟D, 去減少轉向過多.

你所講前約2.5隻手指位, 後 1.5隻手指位, 即係高度上有差不多半寸距離... 後面條彈弓壓得比前面多... 呢個亦可以係一個原因導致 oversteer.

1) You can try to adjust your suspension. Coilover can be adjusted in many ways and you can corner balance the car as well. You may want to soften the front damper and stiffen the rear damper. You will need to test your setting until you satisfy with the result. ;)

2)直路左右高低不等, 很明顯直條行走的車, 會偏走了低的那邊. This is normal. It feels more significant when the car is lowered.
