The present invention discloses an automatic tire tread pattern depth measurement and detection method. The method comprises the following steps that: a first detection device is provided with a putting steel plate in advance to allow the steel plate to cover a rolling shaft of the first detection device, a vehicle travels from a base surface from left to right, the front wheel of the vehicle runsover the steel plate, then passes through the first detection device and runs over a second detection device, when the vehicle wheel presses the two rolling shafts at the innermost side on the seconddetection device, manual stop of the vehicle is performed, the vehicle is switched to a neutral position, a hand brake is released, at the same time, the wheel can perform automatic movement front and back, the wheel at the right side is supported by left and right rolling shafts, and the wheel can achieve centring arrangement with the second detection device. The automatic tire tread pattern depth measurement and detection method avoid the problems that tire tread pattern data is collected by manual operation one by one to cause slow measurement speed, large labor input and low efficiency.
Description
technical field [0001] The invention relates to an automatic tire tread depth measurement and detection method. Background technique [0002] Tires are the only part of the car that is in contact with the ground. It is in contact with the ground all the year round, and it is natural to wear and tear. Not only through the wear and tear of the road surface, but also through the oxidation of the years, all of which threaten the safety of the tires. Tire wear generally refers to the wear of the tire pattern, and the tire pattern is very important. The three most important components of a tire are: tread, carcass and rubber compound, which vary in detail. The three most important functions of the tread pattern are: 1. Improve grip; 2. Reduce noise; 3. Increase drainage. Generally speaking, the thickness of the tread pattern must be greater than 1.6 mm, but if you often drive on wet and slippery roads, it is best to ensure that the tread pattern thickness is greater than 3.2 mm...
