Abstract

The invention discloses a safety traction device for automobile collision test. The main idea is to abandon the release mechanism of the rigid impact of the front end of the traction car, but to use the rear pull braking method to perform flexible separation and release. Specifically, the traction car The brake assembly inside cooperates with the loading bolt and the pressure plate. During the traction process, the brake trolley behind the traction trolley provides the braking force, and the traction assembly in the traction trolley is pulled to move backward to unlock the traction column and traction cable, so that the traction The column falls along the inertial motion direction of the vehicle under test, thereby reliably separating and releasing the vehicle under test. The invention realizes the safe separation and reliable release of the tested vehicle and the traction trolley during high-speed traction operation, effectively solves the damage of equipment and facilities caused by the rigid impact mechanism and the deviation of test accuracy, that is, it can ensure that the tested vehicle after release is The predetermined running trajectory continues to advance, and at the same time, it can also ensure that the state of the dummy in the vehicle under test is more stable.

Description

technical field [0001] The invention relates to the field of vehicle crash test, in particular to a safety traction device used for vehicle crash test. Background technique [0002] Real vehicle crash test is an important means for automobile R&D designers to understand the crash process, master the design data about the crash, and improve the safety design of automobiles. At the same time, customers have higher and higher requirements for the use of automobiles, and the safety of the whole vehicle is the focus of consumers' attention. Therefore, the data in the test process, the accuracy, scientificity, and reliability of the results are the focus of the crash test process. As a vehicle manufacturer, it should pay more attention to the original data of the test results in the process of vehicle model development, which will affect the design of the vehicle. , calibration and verification results, and post-market customer usage will have a significant impact. [0003] In t...
