Embodiment Construction

[0026] first refer to Figure 1A , Figure 1B as well as image 3 The relatively simple two-dimensional suspension assembly 1 shown in FIG. 1 illustrates the basic inventive principles of the present invention. The suspension assembly 1 comprises a support arm 3 and a spring device 5 . The support arm 3 has a length L and is pivotally connected to the chassis 4 about a pivot axis P at one end. The other end links with for example wheel or compartment 6 (as Figure 8 shown). The spring device 5 exerts a spring force F on the support arm 3 s , the elastic force F can be moved toward the pivot axis P or away from the pivot axis P along the support arm 3 (X-axis direction) s , in order to pass the elastic force F s Decrease and increase the moment M applied on the support arm 3 respectively c . Therefore, the torque M can be adjusted c To counteract the external moment M that can act on the support arm 3 in use e . Force F s The displacement of will affect the effectiv...

Abstract

The invention relates to an active suspension assembly and a vehicle equipped therewith. The assembly comprises a bearing arm, spring means and adjusting means. In use, the bearing arm supports the second vehicle mass, for instance a cabin or wheel and is pivotally connected to the first vehicle mass, for instance a chassis, around a pivot axis; the spring means produce a spring force that exerts a counter moment on the bearing arm that can counterbalance any external moment acting on said bearing arm; and the adjustment means are arranged to vary said counter moment by altering the direction of the spring force and / or move its point of application in a first direction. The adjustment means are furthermore arranged to move the point of application of the spring force in a second direction, in which the counter moment is not or hardly affected, but by which the effective spring stiffness of the suspension assembly is affected. Thanks to said latter movement, the effective stiffness of the suspension can be maintained at a desired value.

Description

technical field [0001] The present invention relates to a suspension assembly for a vehicle for suspending a second vehicle body, such as a body or wheels, to a first vehicle body, such as a chassis. More specifically, the present invention relates to active suspension assemblies arranged to actively balance external loads acting on said suspended vehicle body. Background technique [0002] Such suspension assemblies are known, for example, from WO93 / 22150 and WO2006 / 019298. This known assembly comprises a support arm pivotally connected at one end to the vehicle chassis and at the other end coupled to the bodywork or the wheel. Spring means are provided to generate a spring force capable of exerting a moment on the support arm, thereby counteracting forces acting on said support arm due to, for example, lateral, longitudinal and / or vertical accelerations (roll, pitch and heave respectively) of the vehicle external torque on . Adjustment means are provided to alter the di...
