<p>A manual transmission comprises a first and a second selector sleeve 31, 35 which are movable in an axial direction on a shaft 25, 26 between a neutral position and an engaged position in which they couple an idler gear 29, 33 to the shaft 25, 26. A first and a second selector fork 57, 62 act on the selector sleeves 31, 35 in order to control their axial movement. A locking element 58 locks the selector sleeves 35, 31by preventing movement of a coupling arm 43 which is connected to the first and the second selector fork 57, 62 via a first and second joint 44. The arm 43 comprises a pivotal point 54 between the joints 44 on which an actuating element 55 acts that is movable in an axial direction when cams 56 are rotated. The locking element 58 has notches 61 which engage in notches 59, 60 on the selector forks 62 so as to block movement of the forks 62. Twisting of the locking element 58 disengages the notches 59, 60, 61 which allow movement of the forks 62.</p> |
