Abstract

The invention belongs to the technical field of planetary vehicle single-wheel rack devices, and specifically relates to a planetary vehicle single-wheel rack device capable of continuously adjusting a load. The beneficial effects of the invention are that an upper computer achieves the continuous change of a load between a test wheel and soil through controlling the continuous movement of a loading mechanism motor; balancing weights with different weight are symmetrically fixed on a nut of a ball screw, thereby changing the continuous loading range of a single-wheel rack; the rotating motion of the rotating shaft of the loading mechanism motor is transmitted through a planetary gear speed-reducing box and the ball screw, and then is converted into the linear motion of the nut; the motor shaft is provided with an absolute position coder; the miniature linear displacement of the nut is corresponding to a very big angular displacement of the loading mechanism motor because of a speed-reducing ratio and lead, so the value change range of the coder is very large; the driver can control the precise motion of the loading mechanism motor, so the position control precision of the nut is very high, i.e., the high loading precision of a single-wheel rack load.

Description

technical field [0001] The invention belongs to the technical field of a planetary vehicle single-wheel platform device, and in particular relates to a planetary vehicle single-wheel platform device with continuously adjustable load. Background technique [0002] The planetary vehicle can carry people and equipment to walk on the surface of the planet. It is an important tool for human beings to explore the planet, and its performance has a great influence. Because the physical characteristics of the surface of the planet are different from those of the earth, it is necessary to design the planetary vehicle according to the characteristics of the surface of the planet to ensure that the designed planetary vehicle can meet the requirements of use. Therefore, it is necessary to test and test the planetary vehicle through simulation methods on the surface of the earth. In the study of the subsidence of the planetary vehicle walking on the surface of the planet, the existing me...
