Abstract: The present application provides a four-wheel aligner, which includes a first detection device, a second detection device and a control device; the first detection device includes a first position detection module and a first image acquisition module, the second detection device includes a second position detection module and a second image acquisition module, the first image acquisition module and the second image acquisition module are respectively configured to acquire image information on four wheels, in the first position detection module and the second position detection module, one includes a fifth calibration member, and another one includes an image acquisition member, the image acquisition member is configured to capture image information of the fifth calibration member; the control device analyzes the four-wheel alignment information of the vehicle according to the acquired image information.

Abstract: The present application provides a calibration system and a four-wheel aligner. The calibration system includes a first device and a second device for use in pairs. The first device and the second device are respectively arranged on the side of the vehicle to be detected where the wheel to be measured is arranged. The first device includes a first camera, and the second device includes a calibration member. The first camera of the first device is configured to obtain the first image information of the calibration member of the second device on the opposite side. The control device is connected to the first camera, and is configured to receive the first image information from the first camera and process the first image information. The calibration system of the present application obtains the first image information of the second device on the opposite side through the first camera.

Abstract: A wheel hub clamping apparatus and a detection device are provided. The wheel hub clamping apparatus includes: two clamping jaw assemblies, which are configured to clamp on a wheel hub; a guide assembly, which is slidably connected with the two clamping jaw assemblies to enable the two clamping jaw assemblies to move relative to the guide assembly; a driving assembly, which is in transmission connection with the two clamping jaw assemblies and is used to drive the two clamping jaw assemblies to move toward or away from each other on the guide assembly to reach target positions; and a fixing assembly, which is arranged on the guide assembly and is located between the two clamping jaw assemblies, and is used to fix an auxiliary calibration tool.

Abstract: A four-wheel aligner including four four-wheel alignment and measuring devices and two four-wheel alignment and calibration devices; one of the two four-wheel alignment and calibration devices is arranged between two of the four four-wheel alignment and measuring devices located at a side of the vehicle to be aligned, another one of the two four-wheel alignment and calibration devices is arranged between another two of the four four-wheel alignment and measuring devices located at another side of the vehicle to be aligned, and the two four-wheel alignment and calibration devices are configured to be oppositely arranged on two sides of the vehicle to be aligned; the four four-wheel alignment and measuring devices are configured to obtain images of the tires and to analyze alignment information of the tires.

Abstract: A tire tread detection device includes a main body. The main body is provided with a cavity, and a first opening and a second opening that are spaced along a first direction and are in communication with the cavity. The cavity is provided therein with a first camera module and a laser module, the first camera module is configured to capture a tire tread area of a tire to be measured through the first opening to obtain a tire tread image, and a laser line of the laser module passes through the second opening to reach the tire tread area of the tire to be measured to obtain depth data of the tire tread; a control assembly processes the obtained tire tread depth and image information of the tire tread and compares them with the original data to determine the wearing degree of the tire tread.
