Four-wheel-drive automobile chassis dynamometer

Abstract

The utility model relates to a chassis dynamometer of a four-wheel-drive automobile, which belongs to the field of vehicle performance detection. For automobiles with different wheelbases and wheelbases, under the condition that the vehicle does not disintegrate, it simulates the conditions of different road surfaces and detects the vehicle performance. It is characterized in that when the console 15 does not apply voltage to the electrorheological fluid in the second roller frame electrorheological fluid track groove 13, the third roller frame electrorheological fluid track groove 19 and the electrorheological fluid track groove 12 of the movable worktable, the current Change the fluid into a liquid state, and now the second roller frame 14 can move along the slide rail in the second roller frame electrorheological fluid track groove 13, and the third roller frame 17 can move along the inner slide rail in the third roller frame electrorheological fluid track groove 19 Move, the movable workbench 4 can move along the sliding rails in the electrorheological fluid track groove 12 of the movable worktable, when the console 15 applies a voltage to both ends of the electrorheological fluid, the electrorheological fluid solidifies rapidly, and the roller frame is firmly fixed like this Holds securely; the surface of the drum can be sandblasted and waterblasted to simulate different road conditions.

Description

technical field [0001] The invention relates to the field of vehicle performance detection, in particular to a four-wheel drive vehicle chassis dynamometer. Background technique [0002] With the continuous development of the automobile industry, people pay more and more attention to the performance testing of automobiles. However, the wheelbase and wheelbase of different cars are very different, so it is difficult to test different cars on a test bench. At present, there is no one that can simulate the performance of cars with different wheelbases and wheelbases under different road conditions. Test bench for detection. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a test bench capable of testing the performance of automobiles under different road conditions for automobiles with different wheelbases and wheelbases. The invention provides a four-wheel drive vehicle chassis dynamometer, which can simulate the condi...
