Patent DE-4020240-A1 (DE)
Inventor: BADER JOSEF
IPC: F16H61/18
Filed: 1990-06-26
Abstract: The invention concerns a mechanical shift gearbox (1) with downshift securing devices mounted in shifting couplings (2) with synchronizing devices. The shifting couplings (2) comprise a synchronizing element (21) and a shift sleeve (22) mounted on the synchronizing element (21) to move axially but not to rotate, plus synchronizing rings (23) and coupling elements (24) located preferably on both sides. The downshift securing devices are fitted as locking members (3, 4) in the synchronizing element and are capable of limiting, as a function of the centrifugal force, the axial motion of the shift sleeve (22) by means of a stop on the sleeve. When in the enclosed position, the locking members (3, 4) are held by an annular spring (5) in such a way that they do not project beyond the outer surface (210) of the synchronizing element (21), while, in the outside position produced as a result of the centrifugal force, the head (31) of the locking pin (3), which has a centrifugal segment, blocks the shift sleeve by means of the stop at least in one shift direction. In order to increase the mass of the locking elements (3, 4), the centrifugal segment is housed in a recess (211) extending round the edge and is bounded radially on the outside. The centrifugal segment (4) also has a collar-like projection (41) extending into the synchronizing element, the annular spring being held in an outwards-facing groove in this projection. The offset ends (51, 52) of the annular spring (5) hold the spring together with the centrifugal segment (4) in the recess (211).
