Problems solved by technology
[0003] Since each vehicle test requires sensor layout, and different operators are affected by factors such as the difficulty of layout, the selection of measuring points, and the parallelism of pull wires, the above two methods may have large measurement errors and inconsistencies; At the same time, placing the sensor on the suspension is easy to interfere with nearby suspension rods and cause equipment damage

The invention discloses a bench test displacement measurement fixing system. The bench test displacement measurement fixing system comprises a hub collector ring support system and a sensor centeringsupport system. The hub collector ring support system is connected to a tested vehicle hub bearing fixing bolt through a plurality of hole shaft nuts, a conical protruding flange plate is tightly attached to a plane formed by the hole shaft nuts and fixed through the fixing nuts, a telescopic rod is connected with the conical protruding flange plate through a bearing, and a stay wire connector isconnected to the telescopic rod in a threaded mode. An infrared laser level meter and the stay wire type displacement sensor are fixedly placed on a magnetic type installation platform, vertical laserof the infrared laser level meter coincides with a stay wire of the stay wire type displacement sensor, and the stay wire of the stay wire type displacement sensor is connected with a stay wire connector of the hub collector ring support system. The system can directly measure the wheel center displacement, is small in size, light in weight, convenient to arrange, stable in performance and durable, and has a centering function.
Description
technical field [0001] The invention relates to a bench test displacement measurement and fixing system, belonging to the technical field of vehicle bench tests, capable of directly and accurately measuring the displacement of a wheel center in any direction without being affected by wheel rotation. Background technique [0002] In the vehicle bench test, the displacement of the wheel center is often measured to evaluate the ride comfort, comfort and handling stability of the vehicle. At present, the commonly used method for measuring the absolute displacement of the wheel center is: determine a measuring point on the steering knuckle or the control arm to connect the cable of the displacement sensor, which is hereinafter referred to as the cable, and arrange the displacement sensor on the extension line of the displacement track line of the measuring point to measure the vertical displacement. For example, the displacement sensor is arranged directly below the measuring poi...
