四轮定位仪有什么作用?

汽车四轮定位仪是用于检测汽车车轮定位参数,并与原厂设计参数进行对比,指导使用者对车轮定位参数进行相应调整,使其符合原设计要求,以达到理想的汽车行驶性能,即操纵轻便、行驶稳定可靠、减少轮胎偏磨损的精 密测量仪器。
The automobile four-wheel alignment instrument is a precision measuring instrument used to detect the automobile wheel alignment parameters, compare them with the original design parameters, guide the users to adjust the wheel alignment parameters accordingly to make them meet the original design requirements, so as to achieve the ideal automobile driving performance, that is, light operation, stable and reliable driving, and reduce tire eccentric wear.
汽车四轮定位仪是数据采集部分为四个测量探头。测量探头中的传感器分别感应与其相对的测量探头上的红外发射管的光线坐标,经无线发射器传输到机柜中的无线接收器,再经工控机中的COM口传输到电脑主机,进行运算与处理。
The automobile four-wheel alignment instrument is a data acquisition part with four measuring probes. The sensors in the measuring probe respectively sense the light coordinates of the infrared transmitting tube on the opposite measuring probe, transmit them to the wireless receiver in the cabinet through the wireless transmitter, and then transmit them to the computer host through the COM port in the industrial computer for calculation and processing.

由于传感器反映了其自身与相对应的测量探头上的红外发射管的相互关系,而测量探头通过四个轮夹与汽车轮辋相连,所以通过8个传感器可以测量出四个轮辋的相互关系,从而确定车轮的定位参数;8个传感器形成一个封闭的四边形,可实现车辆的四轮定位测量。在实际应用中,4个测量探头上的8个传感器,其镜头前面都装有滤光片,以消除可见光对红外发射二极管亮点图像的干扰。
Since the sensor reflects the relationship between itself and the infrared transmitting tube on the corresponding measuring probe, and the measuring probe is connected with the automobile rim through four wheel clamps, the relationship between the four rims can be measured through eight sensors, so as to determine the wheel positioning parameters; Eight sensors form a closed quadrilateral, which can realize the four-wheel alignment measurement of the vehicle. In practical application, 8 sensors on 4 measuring probes are equipped with filters in front of their lenses to eliminate the interference of visible light on the bright spot image of infrared emitting diode.
数据处理部分为四轮定位仪主机,主要包括一套计算机系统、电源系统及接口系统。其作用是实现用户对四轮定位仪的指令操作,对传感器的图像数据进行采集、处理,并与原厂设计参数一起显示出来,同时指导用户对汽车车轮进行调整,打印出相应的报表。
The data processing part is the host of the four-wheel alignment instrument, which mainly includes a set of computer system, power supply system and interface system. Its function is to realize the user's command operation of the four-wheel aligner, collect and process the image data of the sensor, display it together with the original design parameters, guide the user to adjust the car wheels and print the corresponding report.
四轮定位仪是通过定位角度测量诊断车辆的上述不适症状并予以治疗,它分为前轮定位和后轮定位,前轮定位包括主销后倾角、主销内倾角、前轮外倾角和前轮前束四个内容,后轮定位包括车轮外倾角和逐个后轮前束。
The four-wheel aligner diagnoses and treats the above discomfort symptoms of the vehicle through positioning angle measurement. It is divided into front wheel alignment and rear wheel alignment. Front wheel alignment includes kingpin caster, kingpin inclination, front wheel camber and front wheel toe in. Rear wheel alignment includes wheel camber and rear wheel toe in one by one.
一般情况下,新车驾驶3个月后,就应做四轮定位,之后每行驶1万公里,就应轮胎换位如果发生碰撞,应及时做四轮定位。
Generally, after driving a new car for 3 months, four-wheel alignment should be done. After that, tire transposition should be done every 10000 km. In case of collision, four-wheel alignment should be done in time.
