Embodiment Construction

[0044] exist Figure 1A A first embodiment of a spring 10 according to the invention is shown in side view, and in Figure 1B A first embodiment of the spring 10 according to the invention is shown in plan view, wherein the spring 10 is in a not yet assembled state. The spring 10 has a laminar, in this case disk-shaped, base body 12 with a center point M, which forms a first surface 16 and a second surface 18 . Furthermore, the base body 12 forms three spring arms 20 which have an elongated shape and each have a free end 22 . The spring arms 20 are defined by corresponding cutouts in the base body 12 . Each spring arm 20 defines a longitudinal axis L extending through a free end 22 . The spring arms 20 are designed and aligned such that their longitudinal axis L runs tangentially to a circle C around the center point M of the base body 12 . In addition, the spring arms 20 are evenly distributed on the circumference of the circle C such that the longitudinal axes L enclose a...

Abstract

The present invention relates to a spring (10) for a check valve (40) which can be used in particular in controllable vibration dampers (68), said spring comprising a flat main body (12) with a firstsurface (16), a second surface (18) and a centre point (M), and two or more spring arms (20), which cooperate resiliently with the main body (12) and in the unloaded state protrude from the first surface (16) or the second surface (18), the spring arms (20) forming a free end (22) and having a longitudinal axis (L) that runs through the free end (22) and tangentially to a circle (C) about the centre point (M) of the main body (12). The invention further relates to a check valve (40) having a spring (10) of this kind. In addition, the invention relates to a controllable vibration damper (68) which comprises such a check valve (40), and to a motor vehicle (66) having a controllable vibration damper (68) of this kind.

Description

technical field [0001] The invention relates to a spring for a check valve and a check valve with such a spring. The invention also relates to a controllable shock absorber comprising such a non-return valve and a motor vehicle having such a controllable shock absorber. Background technique [0002] Controllable dampers are known, for example, from DE 38 03 888 C2 and are used in particular for damping force control of motor vehicles in order to adapt the vehicle to the requirements of the driving route. This can be done automatically in the control loop of the motor vehicle. However, it is also possible to manually set the damping force curve by the driver. The design engineering implementation of the shock absorber is usually constructed in such a way that it is possible to detect movements of the body and wheel suspension of the motor vehicle and to select high damping forces in this movement state, in which the resulting damping The direction of the vibration force is...
