Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Note: the specific embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention.

[0026] Specifically, as figure 1 As shown, a test auxiliary device 14 for the rollover test of a semi-trailer and its tractor includes four support assemblies 13 that are fixed and installed on the side of the semi-trailer and the top of the side of the tractor along the longitudinal direction of the vehicle, and are symmetrical about the central axis. The support assembly 13 includes a support 1 , a slide rail 2 , a locking pin 3 , a restriction ear 5 , and a reinforcement piece 8 . Through the above design of the support assembly structure and installation position of the test auxiliary device, during use, when the test vehicle rolls over, the two support assemblies 13 on the same side can stably s...

Abstract

The invention discloses an experiment auxiliary device for a semitrailer rollover test. The experiment auxiliary device comprises four supporting assemblies which are symmetrical about the central axis of a vehicle, wherein the supporting assemblies are installed at tops of two sides of a test tractor and two sides of a test semitrailer, and the heights and the positions of the supporting assemblies can be adjusted by adjusting positions of locking pins, lengths of hollow supporting rods and angles of reinforcing pieces. The experiment auxiliary device is advantaged in that when a roll angle of the test vehicle towards the left side or the right side is larger than a critical value and rollover occurs, the test vehicle is supported in the vehicle body roll-over process, and therefore the effects of protecting the test vehicle and saving test expenditure are achieved; the experiment auxiliary device is simple in structure, convenient to install and light in weight, and does not influence mass distribution and structural arrangement of the test vehicle, and the device is good in transportability and universality, detachable, easy to maintain and replace, simple and convenient to useand capable of effectively protecting the test vehicle.

Description

technical field [0001] The invention relates to a test auxiliary device for the rollover test of a semi-trailer and its tractor. Background technique [0002] When conducting the limit roll test of the semi-trailer and its tractor, due to the large mass of the test vehicle itself and the lack of test auxiliary devices, it is easy to cause damage to the test vehicle during the traditional test process, increase maintenance costs, and prolong the test time. . Contents of the invention [0003] The object of the present invention is to address the above problems and provide a test auxiliary device for the rollover test of a semi-trailer and its tractor. The technical problem solved by the invention is how to effectively protect the test vehicle in the extreme roll test, save the test cost and shorten the test time. [0004] In order to achieve the above object, the present invention provides a test auxiliary device, including four symmetrical support assemblies about the ce...
