[0014] The beneficial effects of the automatic following and flushing wheel hub system device of a car washing machine of the present invention:

[0015] 1. The automatic following and flushing wheel hub system device of the car washing machine of the present invention has a limiting walking mechanism. By operating the walking motor of the limiting walking mechanism, the walking wheels can be driven to rotate. The walking wheels rotate and walk along the walking groove, thereby driving the walking frame to move. While the walking frame moves, the limiting wheel set limits the walking frame to prevent the walking frame from tilting or shifting when walking, enhancing the stability of the walking frame when walking. The walking of the walking frame drives the telescopic rotating mechanism, the flushing mechanism, and the brushing mechanism to perform walking displacement synchronously. The laser positioning probe on the turntable of the telescopic rotating mechanism locates the position of the wheel, so that the walking frame follows the wheel to walk. This device can follow the vehicle movement through the limiting walking mechanism, and can effectively clean the wheel hub through the flushing mechanism and the brushing mechanism while the vehicle is moving, thereby enhancing the cleaning effect of the wheel hub, reducing the total cleaning time of the vehicle, and effectively improving the cleaning efficiency. Through the specially set wheel hub flushing mechanism to spray the cleaning agent and flush the wheel hub, the flushing quality can be effectively enhanced, achieving complete cleaning of the wheel hub.

[0016] 2. The automatic following and flushing wheel hub system device of the car washing machine of the present invention also has a brushing mechanism. The brushing motor of the brushing mechanism can drive the disk brush to rotate. The lifting rod group of the limiting walking mechanism can control the height of the lifting plate and the disk brush of the brushing mechanism, which is applicable to wheel hubs of various sizes. At the same time, this device fixedly installs the flushing mechanism and the brushing mechanism through the rotating fixing ring, and the positions of the flushing mechanism and the brushing mechanism can be interchanged, that is, it reduces the installation space requirement during installation and has strong usability, making it more convenient to use.

[0033] Usage method of the car washing machine automatic following and wheel hub flushing system device of the present device:

[0034] When the device is in use, after the vehicle drives in through the trailer platform, the position of the vehicle wheel hub is located by the laser positioning probe in the middle of the turntable.

The rotation of the bevel gear B meshes and drives the bevel gear A. While the bevel gear A rotates, it drives the protective tube to rotate. The rotation of the protective tube drives the retaining plate and the water outlet pipe to rotate synchronously, so that the nozzle rotates while spraying the cleaning agent on the wheel hub. After spraying is completed, the rotation motor is started. The operation of the rotation motor drives the turntable to rotate. While the turntable rotates, it drives the flushing mechanism and the brushing mechanism to rotate along the sliding ring, so that the flushing mechanism and the brushing mechanism exchange positions. After the position exchange is completed, the brushing motor is started. The operation of the brushing motor drives the cross-shaped clamping sleeve to rotate. The rotation of the cross-shaped clamping sleeve drives the disc brush seat to rotate. The rotation of the disc brush seat drives the disc brush to rotate. While the disc brush rotates, the horizontal telescopic rod is started. The operation of the horizontal telescopic rod drives the disc brush to extend, so as to brush the wheel hub.
