ZFLS Truck Steering Technology/ZFLS卡车转向技术
Variable Ratio/可变速比
| Features/特性 | Benefits/优点 |
| Direct ratio in straight ahead position 在直行位置，直接速比 |
Improved straight ahead driving precision 改善了直行驾驶精度 |
| Indirect ratio starting at 25°sector shaft angle 垂臂轴25°处，开始间接速比 |
Higher output torque at 25°sector shaft angle.Therefore improved steering comfort during dry parking 转角》25°时，输出扭矩变大。因此在干地停车 时提高了转向转向舒适度 In case of a power failure,reduced manual efforts/在助力失效时，大传动比，减少人工用力 |
| Large module/大模数 | High structural reliability/可靠性好 |
