Embodiment Construction

[0024] figure 1 The vehicle body 1 or a part of the vehicle body is schematically shown in . Here, the vehicle body 1 is connected on the left to the spring strut 17 and on the right to the spring device 18 . For ease of viewing, the associated axles and wheels are not shown. However, it should be noted that only the spring struts 17 or spring devices 18 and the respective wheels are always used on an axle.

[0025] The basic structure of the spring strut 17 used for the first axle is, for example: the first spring 6 and the second spring 7 are connected to each other in a series structure, wherein the free end of the first spring 6 is directly or indirectly connected to the vehicle body 1 connected, and the free end of the second spring 7 is connected with the suspension arm 12 or the hub bracket. A hydraulic damper 5 is arranged parallel to the first spring 6 and the second spring 7 . Below the spring 6 , the spring 7 and the shock absorber 5 , the wheel suspension is al...

Abstract

The invention relates to an active electromechanical suspension system for a chassis of a motor vehicle, having a first and a second axis for two opposing wheels (9). Struts (17) having strut actuators (2) are assigned to the first axis for the opposing wheels, and strut arrangements (18) having rotation actuators (3) are assigned to the second axis for the opposing wheels.

Description

technical field [0001] The invention relates to an electromechanical active suspension system according to the preamble of claim 1 for the chassis of a motor vehicle having a first axle and a second axle respectively for two opposing wheels. bridge. Background technique [0002] Currently, electromechanical active suspension systems are constructed according to different principles depending on the vehicle type. The purpose of this system is to further improve driving dynamics and comfort. In this case, different systems have been established within the scope of spring-damping systems, which can be based on electromechanical components – i.e. passive hydraulic dampers or controllable hydraulic dampers or e.g. active The frequency adjustment device - the physical mode of action, that is, pneumatic, hydraulic, electric and divided. [0003] For example, a chassis that can be adjusted is known from DE 10 2004 032 081 A1, which has a first suspension arm / axle guide arm for a ...
