Gearshift device for change-speed gearboxes of motor vehicles

Abstract

In a gearshift device for change-speed gearboxes of motor vehicles, having a shifter shaft (1) movable both axially and radially in the gearbox housing and engaging at one end with an actuating lever arrangement (3) with which in turn corresponding ends of a gearshift linkage or of Bowden gearshift cables engage, substantially parallel to the shifter shaft (1) a supporting pin (6) projecting from the gearbox housing or from a closing plate (2) and having a ball-and-socket joint (7) with only two degrees of twisting freedom is provided, on which is supported a three-armed actuating lever (8), the three arms (9, 10 and 11) of which are disposed perpendicular to each other in the manner of orthogonal axes of coordinates, one of said arms (9) being connected by way of a ball-and-socket joint (12) to a pin (4) projecting radially from the shifter shaft (1) and the two other said arms (10 and 11) being connected by way of their ball-and-socket joints (13 and 14) to the corresponding ends of a gearshift linkage or of Bowden gearshift cables (not shown).
