Abstract
The invention concerns a gearbox (9). On the gearbox is front-mounted a hydrodynamic torque converter (3). The gearbox (9) has hydraulically actuatable gear clutches (17, 18, 23 and 28) which are designed structurally alike. The gears (14, 15, 16, 19, 20, 21, 22, 24, 26 and 27) are in constant engagement with each other. In order to reduce the development of noise, the gears are high and helically toothed. The gearbox is especially suited for use in vehicles in which special importance is attached to comfortable riding. Such vehicles are, for instance, passenger cars and mobile homes.
Claims11
A gear box (9) for a vehicle having an input shaft (10) upon which a center gear (14) is fixedly supported, two side gears (15, 16) being rotatably supported on said input shaft (10), one said side gear being located on each side of said center gear (14) and each said side gear (15, 16) being engagable with said center gear (14) by respective input shaft gear clutches (17, 18), a drive shaft (11) being paraxially aligned relative to said input shaft (10) and having two gears (19, 20) fixedly supported on said drive shaft (11), said two fixed gears (19, 20) of said drive shaft (11) meshing with said two side gears (15, 16) of said input shaft (10), and a further gear (22), meshing with said center gear (14), being rotatably supported on said drive shaft (11) and being engagable with one of said fixed gears (19, 20) of said drive shaft (11) by a drive shaft gear clutch (23),
- wherein an additional gear (21), operatively connected with a gear (24) of an axle-drive shaft (13), is fixedly supported on said drive shaft (11), and
- a gear (26) is fixedly supported on a reversing shaft (12) paraxially aligned with respect to said input shaft (10), said gear (26) of said reversing shaft (12) meshes with said center gear (14) of said input shaft (10), and a gear (27), rotatably supported upon said reversing shaft (12), is engagable by a reversing shaft gear clutch (28) and meshes with one of said fixed gears (19, 20, 21) of said drive shaft (11).
