Problems solved by technology
[0004] The purpose of the present invention is to provide a tire blowout test platform to solve the problem that the blowout device in the form of deflation is difficult to meet the time requirements for blowout and deflation, and the perforation of the wheel hub affects the safety of the blowout test and training. The piercing device cannot independently test the front and rear wheels, and cannot flexibly meet different test requirements

Embodiment Construction
[0028] like Figure 1 to Figure 6 As shown, the present embodiment provides a tire blowout test platform, including a platform body 1 and a tool holder 2, please refer to figure 1 , the cross section of the platform body 1 is trapezoidal, the platform body 1 successively includes an upslope surface 3, a test surface 4 and a downslope surface 5, the test surface 4 is preferably a horizontal plane, the tool holder 2 is installed on the test surface 4, and the micro switch 6 Installed on the downslope 5.
[0029] Specifically, such as figure 2 and image 3 As shown, the test surface 4 of the platform body 1 is provided with a knife seat groove, and the knife seat 2 is embedded in the knife seat groove; the knife seat 2 is hinged with a piercing body 7 with a sharp end through a hinge, and the hinge can be Choose a spring hinge with a fixed angle, which can fix the piercing body 7 at a specific angle of inclination, so that the piercing body 7 stands obliquely in the direction...

The invention provides a tire burst test platform, which comprises a platform body and a tool apron. The tool apron is arranged in a tool apron groove in the top surface of the platform body. A piercing body is hinged to the tool apron through a hinge and can obliquely stand in the vehicle coming direction to be in a test posture. A plate spring with an arched middle is installed below a rear seatof the piercing body, and after the front wheels press the piercing body, the piercing body can extrude and deform the two ends of the plate spring upwards, so that the plate spring rebounds to the piercing body. An electromagnet is mounted on the tool apron and can adsorb the rebounded piercing body. A compression spring is installed in the tool apron, and when the electromagnet loses power, thecompression spring can jack up the piercing body to a test posture. A micro-switch is installed on the platform body and located on the downstream portion of the piercing body, the micro-switch is connected with a controller, and the controller is connected with the electromagnet. According to the invention, the problems that a tire burst device can hardly meet the time requirement of tire burstdeflation, cannot test the front wheels and the rear wheels independently, and cannot flexibly meet different test requirements can be solved.
Description
technical field [0001] The invention belongs to the technical field of automobile testing devices, and in particular relates to a tire blowout testing platform. Background technique [0002] At present, there are relevant laws and regulations for the emergency protection of steering wheels of passenger cars and transport trucks. The automobile proving ground also develops tire burst tests or related driving training based on the requirements of relevant laws and regulations. Most of them take the form of inflation and deflation. Install a number of air pipes controlled by solenoid valves. By controlling the solenoid valves, the air pipes are used to inflate or deflate the tires. The holes on the wheel hub are large and numerous, seriously affecting the safety of the testing and training process. However, the relevant regulations on tire blowout control for passenger cars have stricter requirements on the time for deflation of tire blowouts. The test device in the form of ra...
