Suspension system, preferably driver seat

Abstract

The invention relates to a suspension system (1), preferably a driver seat (1), comprising a first suspension part (10), preferably a frame (10) of the driver seat (1); a second suspension part (11),preferably a seat surface (11) of the driver seat (1), wherein the two suspension parts (10, 11) are movable relative to each other in at least one first spatial direction (Z), preferably in the vertical direction (Z); a kinematic system (12), preferably a scissor kinematic system (12) which is designed to connect the two suspension parts (10, 11) in a movable manner relative to each other at least in the first spatial direction (Z); a suspension device (13) which is designed to support the static load of the second suspension part (11); and an actuator (2) which is designed to introduce a force bidirectionally between the two suspension parts (10, 11) and thereby actively damp the relative movement between the two suspension parts (10, 11). The suspension system (1) is characterized in that the actuator (2) has a bearing (28), preferably a ball bearing (28), which is arranged within the power flow between the two suspension parts (10, 11) such that an axial load can be kept away fromthe driven axle of the actuator (2) at least partly, preferably completely.

Description

technical field [0001] The invention relates to a suspension system, preferably a driver's seat, as claimed in the preamble of patent claim 1, and also to a vehicle comprising such a suspension system as claimed in patent claim 15 . Background technique [0002] It is known in the field of vibration damping that in a very wide range of applications vibrations between a fixed suspension part and a suspension part which is movable relative to said fixed suspension part must be damped. These applications include driver seats in some vehicles (eg, trucks, buses, etc.). In this case, vibrations that may be introduced into the vehicle from the roadway should generally be kept away from the driver by damping the driver's seat in order to protect the driver in particular during relatively long journeys. This is not only aimed at increasing the driver's comfort (especially on relatively long trips), but also at protecting said driver's health, and also in this way to increase durab...

Problems solved by technology

However, this leads to increased costs, to increased space requirements and also to increased weight, each of which is disadvantageous

[0009] Another disadvantage is that the actuating element of the device of EP 2 921 342 A2 has a non-linear characteristic of the rotational speed with respect to the stroke

This may lead to a non-linear dependence between the constant rotational speed of the actuating element and the final stroke, and this will lead to a non-linear control or regulation which may lead to worse results than a linear relationship
