Outer part of the steering mechanism, outside the gearbox, it engages the gearshift lever with the shaft of the internal part of the control mechanism protruding beyond the gearbox housing. The outer part consists of a system of tendons or connectors, shaped and connected according to the design of the car and the location of the gearbox therein. Sometimes the outer part of the mechanism is only the gear lever, directly inside the gearbox and directly moving the slides of the internal mechanism.
Most gearboxes use a crosshead gearshift as an internal part of the control mechanism. A fork that directly moves the switched element in the gearbox (gear, synchronizer outer ring etc.) są zamocowane na wajiku, also sliding. Each fork has a corresponding slider. The slides are attached to the slides in this position, that the end of the control lever that goes into the box, in the slack position, after being moved in the direction, only one of the sliders may select. After selecting the track stick you want, you can move it forward or backward, engaging the gear corresponding to this movement.
The slides are secured against turning with the lugs and against undesirable movement - with spring latches. In addition, a special locking system, acting on the sliders, prevents the simultaneous selection of two gears and against accidental engagement of reverse gear when driving forward.
