Claim 1
Independent Claim
143 words
A gear-shift mechanism for a change-speed transmission equipped with speed-range selection means for motor vehicles, said mechanism (6) comprising: a multi-speed gear-shift transmission unit and a range-shift transmission unit; a shift control lever (7) actuating via a gear-selector passage (21) and via several gear-shift passages a gear-shift shaft (27) rotatively supported and axially moveable inside a housing (11); gear-shift levers (13, 14) loosely supported on said shaft and lockable in a non-revolving manner; said gear-shift shaft (27) including two coupling elements (28, 29) co-axially and spatially disposed thereon and alternately moveable into a non-revolving engagement with said gear-shift levers (13, 14); said range-shift transmission unit being operated by a shifting mechanism (40) controlled by a shift finger (37) mounted on and axially moveable together with said gear-shift shaft; and said finger limitedly rotating about said gear-shift shaft (27) and axially immobile relative thereto.

Claim 6
Dependent Claim
26 words
The gear-shift mechanism according to claim 3, wherein said pin-shaped end section (49) engages from below said receiving bore (48) provided in said gate plate (44).
Claim 7
Dependent Claim
47 words
The gear-shift mechanism according to claim 3, wherein a hub section (52) of said shifter lever (16) is supported in a revolving arrangement on a bearing shaft (53) extending parallel to said gear-shift shaft (27) and being located in a detachable cover (54) of said housing (11).
Claim 8
Dependent Claim
61 words
The gear-shift mechanism according to claim 3, wherein said shift finger (37) has a sleeve member (38) supported on said gear-shift shaft (27) in a revolving arrangement; said shift finger having a guide head (39) projecting radially outwardly from said sleeve member (38) and moveable within said slot (43) of said gate plate (44); and said slot having a curvilinear configuration.
Claim 9
Dependent Claim
43 words
