Embodiment Construction

[0017] In this description, reference is made by way of example only to "inverted" fork-type front shocks for mountain bikes. However, the invention can also be applied in different types of shock absorbers, for example in standard forks, in other words in shock absorbers that are not of the "inverted" type, which is a challenge for those skilled in the art. It will be obvious to the personnel.

[0018] Reference attached figure 1 , with reference numeral 100 representing a bicycle shock absorber. As discussed above, the shock 100 may be, for example, an inverted fork type front shock for a mountain bike.

[0019] The shock absorber 100 includes an elastic device 200 and a damping device 1 . The elastic device 200 substantially elastically performs the function of damping and storing energy transmitted from the ground to the bicycle wheel, while the damping device 1 has the function of partially dissipating such energy. according to figure 1 In an exemplary embodiment of ...

Abstract

A damping device (1) for a suspension (100) of a bicycle, comprises: a first tubular body (2), the interior thereof defining a first chamber (4); a second tubular body (3) axially slidable with respect to the first tubular body (2), the interior thereof defining a second chamber (5) fluidically communicating with the first chamber (4); a third tubular body (8) disposed inside the second chamber (5) and integral with the second tubular body (3), the interior thereof defining a third chamber (9) fluidically communicating with the second chamber (5); a hollow stem (10) integral with the first tubular body (2), wherein the interior thereof defines a through cavity (11) which establishes a fluid communication between the third chamber (9) and the first chamber (4); a first static valve (12) operatively disposed between the second chamber (5) and the third chamber (9); a second static valve (14), integrally connected to the stem (10), operatively disposed between the third chamber (9) and the cavity (11) of the stem (10); a dynamic valve (15) connected to the first tubular body (2) inside the first chamber (4), operatively disposed between the cavity (11) of the stem (10) and the first chamber (4). The dynamic valve (15) comprises a stationary body (22) having one or more openings for the passage of a fluid, and a shutter (24) movable with respect to the stationary body (22) in orderto modify the free cross-section of said one or more openings, the shutter (24) being moved by a rotary actuator (25).

Description

technical field [0001] The object of the invention is a damping device for a shock absorber of a bicycle, in particular a front shock absorber of a bicycle such as a mountain bike. Background technique [0002] A suspension is known in which the damping action of the suspension itself, in particular its damper, can be adjusted. In particular, shock absorbers are known in which the damping action is adjusted by means of a solenoid valve which affects the recirculation of oil on the shock absorber itself. Solenoid valves are magnetic induction devices in which a solenoid (in which an electric current flows) moves a ferrous mechanical element which in turn determines an axial element which causes the opening, closing, or partial opening / closing of an oil passage opening vertical movement. This jamming action modifies the damping action performed by the shock absorber. [0003] However, solenoid valves are unsuitable devices for mounting to bicycle shocks, particularly becaus...
