The invention provides a method for simulating real impact test of vehicle wheels, and the method is implemented using a system as follows: the system includes a vehicle used in wheel simulating real impact test, a road surface, a high-frequency lighting facility, a standard obstacle block, a high-speed camera, and a traction motor and steel cable. The method for simulating real impact test of vehicle wheels of the invention has the advantages that: the need for testing various types of wheels using one set of equipment can be satisfied by using a general type collision trolley, thereby avoiding the use of a corresponding real vehicle for each type of wheels in the test. This greatly reduces the test cost, ensures that the test condition is similar to the real vehicle condition, and can well simulate the performance of a real vehicle when meeting an obstacle.


A device and method for measuring the thickness and position tolerance of a wheel bolt hole. The device includes a screw, a handle, a detection pillar and a base plate, where the handle and the base plate are fixed via the screw; the detection pillar is fixed onto the base plate through interference fit; and the detection pillar a bolt hole. The position tolerance and thickness of a bolt hole are measured simultaneously, and the labor intensity is reduced, and the existing bolt hole position tolerance detection tool can be modified for the use as the tool of the device, saving costs. The tool can detect the thickness of a bolt hole and qualitatively determine the range where the difference between the value of bolt hole thickness and the standard value approximately lies, and can be used for the grading of bolt hole thickness values based.


The invention relates to a device and method for detecting the wheel center depth of an aluminum wheel cast blank, the device includes a roller way tray, a position sensor, a frame, a CCD camera, a programmable controller and a laser distance measurement sensor, an upper servo-cylinder, a motor support, a servo-motor and a lower servo-cylinder. The invention has the following advantages: the method for automatically detecting and identifying the wheel center depth of an aluminum wheel cast blank is utilized for the identification and classification of wheel cast blanks, so as to reduce the influence of large casting dimension tolerance on the machining dimension tolerance, increase the acceptability rate of products from the automatic machining unit, ensure that the production line automatically runs with high quality and quantity and also reduce the labor intensity of operators.
