Multi-connecting-rod suspension mechanism with buffering, folding and steering functions

Abstract

The invention provides a multi-connecting-rod suspension mechanism with buffering, folding and steering functions. The multi-connecting-rod suspension mechanism with the buffering, folding and steering functions comprises an upper connecting rod structure, a lower connecting rod structure, an upper steering block, a lower steering block, a shock absorber, a torsion rod spring and a steering mechanism; one end of the upper connecting rod structure is connected with the upper side of a wheel hub shaft part through the upper steering block; the other end of the upper connecting rod structure is connected with a bottom plate; one end of the lower connecting rod structure is connected with the lower side of the wheel hub shaft part through the lower steering block; the other end of the lower connecting rod structure is connected with the bottom plate; the upper steering block and the lower steering block have two rotation freedom degrees; the normal direction of one rotation freedom degreeis perpendicular to to the axis of a wheel and points to the front; the normal direction of the other rotation freedom degree is perpendicular to to the axis of a wheel and points to the downside; oneend of the shock absorber is connected with the upper side of the wheel hub shaft part through the upper steering block; the other end of the shock absorber is connected with the bottom plate; the torsion rod spring is mounted in the axis directions in which the upper and lower connecting rod structures are connected with the bottom plate; the steering mechanism mainly comprises four connecting rod mechanisms; one end of the steering mechanism is connected to the lower end of a steering wheel; and one end of the steering mechanism is connected to the wheel hub shaft part.

Description

technical field [0001] The invention relates to a multi-link suspension mechanism, in particular to a foldable multi-link suspension mechanism with buffering and steering functions, which is suitable for space planetary vehicles with high requirements for functional integration and limited space layout. [0002] technical background [0003] At present, the car suspension has independent functions, but it occupies a lot of weight and space envelope, and is not suitable for space planetary vehicles with high requirements for functional integration and limited space layout. Contents of the invention [0004] Aiming at the shortcomings of the current automobile suspension, the invention relates to a foldable multi-link suspension mechanism with buffering and steering functions, which has a buffering function and can adapt to the uneven topography of the planet's surface; It saves space resources; at the same time, it has a steering function, which simplifies other mechanisms. ...
