Active suspension stability life verification device

Abstract

The invention discloses an active suspension stability life verification device which comprises an included angle adjusting mechanism fixed on an included angle fixing device and further comprises a front main rocker arm loading verification device and / or a rear main rocker arm loading verification device, wherein the front main rocker arm loading verification device comprises a front main rocker arm and a first loading device, and the front main rocker arm is connected with an included angle front main rocker arm output shaft of the included angle adjusting mechanism; one first wheel assembly is mounted on the front main rocker arm; the first loading device is placed at the lower part of the first wheel assembly; the rear main rocker arm loading verification device comprises a rear main rocker arm, an auxiliary rocker arm and two second loading devices; the rear main rocker arm is connected with an included angle rear main rocker arm output shaft of the included angle adjusting mechanism; the auxiliary rocker is connected with the rear main rocker; two second wheel assemblies are mounted on the auxiliary rocker arm; and the two second loading devices are respectively arranged at the lower parts of the two second wheel assemblies. According to the invention, the stability and the service life of an active suspension under the driving bumpy load can be tested and verified.

Description

technical field [0001] The invention relates to the technical field of a planetary vehicle test device, in particular to an active suspension stability life verification device. Background technique [0002] Planetary vehicles travel on different planets, and their terrains are complex and changeable, including flat ground, soft soil, gravel roads, gravel roads, climbing, and overcoming obstacles. In order to adapt to the complex terrain, my country's Mars rover has designed a rocker-type active suspension mechanism. A single-input and double-output angle adjustment mechanism with self-locking function is designed at the main shaft to adjust the front main rocker arm and the rear main rocker. The included angle of the arm, and keep this position will not change due to bumps and long-term force. [0003] However, there is no device in the prior art that can simulate the bumpy terrain on the surface of the planet, and verify key indicators such as the self-locking ability, sta...
