Gear selection system includes set of three springs acting on selector shaft and stop and disk unit subordinate to axial movement of pre-tensioner.

摘要

In the neutral position the pre-tensioner (4) is pre-clamped to a guide element (3) by the second spring (8) as opposed to the driver (10) which is pressed by the spring loaded (7) selector shaft (2) onto the pre-tensioner (4) in the opposite direction. A further spring (9) loads the stop disk (6) onto the endstop in the same way as the pre-tensioner. In the first selection position the shaft (2) pre-cocks the spring (7) so this urges the pre-tensioner axially away from the disk (6) on the guide element (3). Disk (6) is loaded onto the stop (5) by the spring (9). In the second selection position the pre-tensioner (4) is moved axially free from the guide and so against the spring (7) towards the disk (6) which in turn is loaded by spring onto the stop (5) opposite to the pre-tensioner (4).
