Expandable and actively adjusting balanced suspension system

Abstract

The invention belongs to a reactive suspension system, and more particularly relates to a reactive suspension system which can be folded and unfolded and actively adjusted and solves the technical problems of having complex structure, poor stability and not being extensible of the reactive suspension system. The reactive suspension system comprises a front bodywork, a rear bodywork, a bodywork folding and unfolding mechanism, two lateral reactive suspension groups and a transverse reactive suspension group. The two lateral reactive suspension groups are respectively articulated at the left side and the right side of the front bodywork, and can freely rotate in a certain range at the side of the bodywork; and the rear bodywork is articulated with the front bodywork at the transverse surface by the bodywork folding and unfolding mechanism, and can freely rotate in a certain range in the transverse direction of the bodywork to form a transverse reactive suspension. Two upright rods of the two lateral reactive suspension groups are always vertical to the horizontal plane of the bodywork and face upwards in any circumstances, thus ensuring the steering axis of wheels is superpositioned with the earthing contact of the wheels, and reducing the steering resistance while ensuring the steering accuracy; simultaneously, the normal line of ground bracing force borne by the two wheels passes through the center of a hinge, thus avoiding a bar system from bearing additional torque, and being capable of greatly reducing the weight of the parts.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension systems, and in particular relates to a retractable and actively adjustable balance suspension system with a six-wheeled vehicle running plan arrangement. Background technique [0002] With the development of electric-driven independent drive and independent steering wheel technology, the arrangement of six wheels or more is more and more applied to various alien exploration vehicles and ground autonomous vehicles. The flexibility of the wheel arrangement and the increase in the number of wheels provide more freedom and flexibility for the arrangement of the suspension. At present, most of the known extraterrestrial exploration vehicles use multi-wheel side-by-side rocker suspension mechanisms as the main configuration of the walking system. For example, the "Lunokhod 1" and "Lunokhod 2" launched by the Soviet Union adopted a parallel 8-wheel structure with unilateral double rocker sus...

Problems solved by technology

In addition, due to structural limitations, these suspension systems can only achieve very limited folding and expansion of the vehicle chassis, which is not convenient for further impro
