1 转向检测参数的选择汽车转向系统性能好坏直接影响汽车的安全。微机汽车转向盘转向参数测试仪是检测和评价汽车转向性能好坏的重要设备,主要用以检测汽车转向盘的自由行程、转向角和转向力。1.1 转向盘自由行程(转角) 转向盘自由行程是指汽车转向轮位于直线行驶状态时转向盘自由转动的角度,又称“转向盘自由转角”或“转向盘自由转动量”。当转向盘自由行程过大时,说明从转向盘到转向轮运动传递链中的若干配合副团磨损过度而出现松旷现象。因此,转向盘自由行程是一个综合诊断参数。根据GB 7258—1997《机动
1 steering detection parameter selection Car steering system performance directly affects the safety of the car. Vehicle steering wheel steering parameter tester is to detect and evaluate the car steering performance is an important equipment, mainly used to detect the car’s steering wheel freewheeling, steering angle and steering force. 1.1 steering wheel freewheeling (corner) Steering wheel free travel refers to the car steering wheel is located in a straight line when the steering wheel freewheeling angle, also known as “steering wheel free corner” or “freewheeling steering wheel.” When the steering wheel free travel is too large, indicating from the steering wheel to the steering wheel movement of the transmission chain with a number of supporting deputy group excessive wear and loose Song Kuang phenomenon. Therefore, the steering wheel free travel is a comprehensive diagnostic parameters. According to GB 7258-1997 "Mobile
