Problems solved by technology

However, most of the above-mentioned test benches cannot take into account both the crash test of the whole vehicle and the simulated crash test of the trolley, that is, "one unit is dual-purpose"; at the same time, most of the test benches need to be treated to a certain extent before the guide device can be installed, and the guide device cannot meet the requirements of the wheelbase. The need for larger test vehicles

Embodiment Construction

[0012] The present invention is an automobile crash test device. The device consists of a fixed wall 1 , a track 2 , a rubber rope 3 , a buffer 4 , a test car 5 , a pulley 6 , a release mechanism 7 , a release trolley 8 , a wire rope 9 , a hoist 10 and a guide mechanism 11 . like figure 1 shown,

[0013] The track 2 is fixed on both edges of the test deep groove in front of the fixed wall 1. One end of the rubber rope 3 is fixed with the pulley 6, and the other end is fixed in front of the fixed wall 1. The two sides of the pulley 6 are respectively connected with the guide mechanism 9. The test car 5 Pushed by the trolley 6 and bound by the guide mechanism 11 on both sides; buffers 4 are respectively arranged at the same position between the fixed wall 1 and the two rails 2 between the trolley 6 . During the test, the pulley 6 is pulled by the hoist 10 through the release trolley 8 and the release mechanism 7, so as to realize the loading of the rubber rope 3. After the ru...

Abstract

The invention discloses an automobile impact test device used for automobile passive safety detection, composed of fixed wall, railway, buffer, release mechanism, guide mechanism and sliding vehicle. The sliding vehicle is connected with the release mechanism and the guide mechanism, and the test vehicle is controlled in the middle of the guide mechanism. The main idler wheel, side shaft idler wheel and vertical idler wheel of the guide mechanism limit the guide idler wheel to move in the vertical and side directions of the guide rail, and at the same time, the movement has considerably small friction resistance. The space adjusting mechanism can implement stepless adjustment of space between guide members. The test vehicle has very strong adaptability and is uneasy to damage structure. The release mechanism works stably, easy to operate and accurately locates. It combines the impact test of the whole vehicle with the automobile simulated impact test in a test table, successfully implementing 'a test table for two uses'.

Description

technical field [0001] The invention belongs to the field of automobile safety testing, in particular to an automobile collision test device used for automobile passive safety detection. Background technique [0002] Crash test is an important method in the study of passive safety of automobiles. The safety features of the car can be improved through crash testing, and the vehicle can be certified for safety at the same time. International automobile safety regulations and the newly implemented Chinese automobile safety regulations have strict regulations on automobile crash tests. In my country, the issue of automobile safety has attracted the attention of relevant departments. So far, 40 mandatory automobile safety regulations have been implemented, including requirements for seats, seat belt anchorage points, and seat belt assemblies. In 1999, the State Bureau of Machinery Industry promulgated the certification regulations (CMVDR294) for the form of frontal collision oc...
