Abstract
The invention relates to a power assist element (11) for arranging in a synchronization hub (2) of a gear-synchronization device (1), with a basic body (17), which has a height (18), a longitudinal extension (19) and a width extension (20), wherein the longitudinal extension is arranged in the installed state in the circumferential direction of the synchronization hub (2), and which in the direction of the longitudinal extension (19) has two opposite distal end sections (21), on which respectively a functional face (22) is formed, which in the installed state cooperate with the synchronization hub (2). The functional faces (22) are inclined in opposite direction and relative to the longitudinal extension (19) or are designed to be offset relative to one another along a longitudinal middle axis (37) in the direction of the longitudinal extension (19) of the basic body (17), wherein the functional faces (22) are oriented respectively at an acute angle (23) to the greatest longitudinal extension (19) of the basic body (11).
