Embodiment Construction

[0027] The present invention will be further elaborated below in conjunction with embodiment.

[0028] The invention provides an active suspension with adjustable attitude and variable damping for a manned lunar surface mobile system. During the moon landing process of the lunar surface mobile system, the suspension needs to have the buffer characteristics of large stroke and large damping; When the driver drives the mobile system, the mobile system needs to have high ride comfort. The invention solves the problem that the suspension stiffness and damping characteristics do not match in the above two working conditions.

[0029] Such as figure 1 As shown, the attitude-adjustable damping active suspension mainly includes wheels 1, upper cross-arm 2, lower cross-arm 3, frame 4, steering electric cylinder 5, attitude-adjusting electric cylinder 6, drive motor assembly 7 and friction damper vibrator 8; wherein, the wheel 1 is axially placed horizontally; one axial end of the upp...

Abstract

The invention relates to an active suspension with adjustable attitude and variable damping for a manned lunar surface mobile system, belonging to the design field of a manned lunar surface mobile system; the axial end of the upper cross arm is rotatably connected with the hub of the wheel; The other axial end of the lower cross arm is rotationally connected with the frame; the axial end of the lower cross arm is rotationally connected with the wheel hub; the other axial end of the lower cross arm is rotationally connected with the frame; the friction shock absorber is arranged on the upper cross arm and the frame The rotating connection of the attitude adjustment electric cylinder is arranged at the bottom of the vehicle frame; the drive motor assembly is arranged at the bottom of the attitude adjustment electric cylinder; the steering electric cylinder is arranged at the side wall of the drive motor assembly; the vehicle frame is always placed horizontally; the invention has The active lifting function can realize the attitude adjustment of the mobile system; at the same time, the suspension shock absorber can realize the change of damping according to different angles, through the active adjustment of the suspension and the change of damping, the large-stroke landing buffer and smooth driving of the mobile system can be realized sex.

Description

technical field [0001] The invention belongs to the design field of a manned lunar surface mobile system, and relates to an attitude-adjustable variable damping active suspension used for a manned lunar surface mobile system. Background technique [0002] In the field of manned lunar landing, it may involve lunar mobile systems (or lunar vehicles), such as the Apollo lunar landing program. During the lunar landing process of the lunar surface mobile system, the lunar surface mobile system can be used for direct landing and buffering. During the landing process, in order to reduce the force on the wheels and the entire mobile system, the suspension is required to have a large stroke Damping and buffering characteristics; after landing, when the astronauts drive the mobile system, the suspension is required to have small damping characteristics for normal driving, so as to meet the smoothness of the mobile system and the comfort of the astronauts. At present, no related mater...
