<p>The present invention pertains to a synchromesh device for a gearbox. The synchromesh device comprises an annular coupling element (5, 14), a latch cone (6, 9) and a coupling cone (7, 10). The coupling element (5, 14) is shiftably arranged in an axial direction between a first end position, in which the coupling element (5, 14) is freely rotatable in relation to the coupling cone (7, 10), and a second end position, in which the coupling element's cogs (5a, 14a) engage with the coupling cone's cogs (7a, 10a). The synchromesh device comprises a slot-shaped space between a radially external control surface (5c, 14c) of the coupling element (5, 14) and a radially internal control surface (6c, 9c) of the latch cone (6, 9), and a lock element (8, 11) arranged inside said space. Said control surfaces (6c, 9c) are designed in such a way, that the lock element (8, 11) establishes a connection between the coupling element (5, 14) and the latch cone (6, 9) in a connecting position, located at a distance from the first end position, so that the latch cone (6, 9) is moved along by the coupling element (5, 14) during a continued movement towards the first end position, up to a position in which the latch cone's conically shaped friction surface (6a, 9a) is located at a distance from the coupling cone's conically shaped friction surface (7a, 10a).</p> |
