Vehicle component with a magnetorheological braking system

Abstract

A vehicle component (140) with a stator (141) and with a magnetorheological braking device (1) having two braking components (2, 3), wherein the two braking components (2, 3) are movable relative to each other and define an axial direction (20). A gap (5) is formed between the first and the second braking component (2, 3), at least partially filled with a magnetorheological medium (6), and has at least one effective gap section (5c) extending between the braking components (2, 3). The magnetorheological medium (6) comprises particles (19). The effective gap section (5c) is exposed to a magnetic field (8) of a magnetic device (28) to effect a braking action against the relative movement of the two braking components (2, 3) relative to each other. Rotatable transmission components (11) are arranged in the gap (5) to enhance the braking effect.
