Embodiment Construction

[0018] as available from figure 1 As seen in the figure, the shock absorber 26, which is preferably configured as a shock absorber for a vehicle according to the present invention, includes a shock absorber cylinder 28 filled with the shock absorber fluid 14, in which the shock absorber cylinder 28 can move A piston unit 30 is arranged in a manner that includes a piston rod 32 and a piston plunger 34 , wherein the piston plunger 34 is guided in the shock absorber cylinder 28 via the piston rod 32 . The piston punch 34 divides the shock absorber cylinder 28 into an upper shock absorber chamber 36 and a lower shock absorber chamber 38 . During the axial movement of the piston rod 32 and thus the piston punch 34 relative to the shock absorber cylinder 28, preferably in the direction of the vertical axis 40 of the shock absorber 26, the shock absorber fluid 14 must pass through the The flow through device 42 inside the shock absorber cylinder 28 to flow, the flow through device 4...

Abstract

The invention relates to a spring unit (10) for a damper (26), comprising at least one spring element (12a, 12b), which can be used to control a flow of a damping fluid (14) through at least one flow channel (16) in order to set characteristic damping values, the channel comprising at least one control gap (18a, 18b) for specifying a characteristic damping curve, and a corresponding damper (26), in particular for a vehicle, which has at least one spring unit (10) according to the invention for setting characteristic damping values. According to the invention, the at least one spring element (12a, 12b) comprises a spring disk (12.1 a, 12.1 b) having a cut-out spring tongue (12.2a, 12.2b), which forms the at least one control gap (18a, 18b) with an inside wall (16.1) of the flow channel (16).

Description

technical field [0001] The invention relates to a spring unit for a shock absorber of the type specified in independent claim 1 and a corresponding shock absorber, in particular for a vehicle, which comprises at least one such spring unit. Background technique [0002] Passive damper pistons are known from the prior art, for which a spring unit with a spring element configured as a spring leaf set is usually used, the spring element comprising a plurality of spring elements for generating a specific The spring leaf of the damping force characteristic curve. The spring rate of the spring blade set in these conventional shock absorber pistons is calibrated once during the development process and can no longer be adjusted. This principle enables a cost-effective and durable construction of the damper piston with a simultaneously good and practically proven variation of the damper characteristic curve. [0003] A shock absorber for a vehicle is described in the laid-open docum...
