ZFLS Truck Steering Technology/ZFLS卡車轉(zhuǎn)向技術(shù)
Variable Ratio/可變速比
| Features/特性 | Benefits/優(yōu)點(diǎn) |
| Direct ratio in straight ahead position 在直行位置，直接速比 |
Improved straight ahead driving precision 改善了直行駕駛精度 |
| Indirect ratio starting at 25°sector shaft angle 垂臂軸25°處，開始間接速比 |
Higher output torque at 25°sector shaft angle.Therefore improved steering comfort during dry parking 轉(zhuǎn)角》25°時(shí)，輸出扭矩變大。因此在干地停車 時(shí)提高了轉(zhuǎn)向轉(zhuǎn)向舒適度 In case of a power failure,reduced manual efforts/在助力失效時(shí)，大傳動(dòng)比，減少人工用力 |
| Large module/大模數(shù) | High structural reliability/可靠性好 |
