PCT No. PCT/SE92/00627 Sec. 371 Date Mar. 8, 1994 Sec. 102(e) Date Mar. 8, 1994 PCT Filed Sep. 11, 1992 PCT Pub. No. WO93/05317 PCT Pub. Date Mar. 18, 1993.Transmission for boats, comprising an input shaft (2), a reversing mechanism and an output shaft (3). The reversing mechanism is comprised by a right angled bevel gearing with two bevel gears (7, 8), which are freely rotatably mounted on an intermediate shaft (4) and engaged with a bevel gear (6) on the input shaft. The bevel gears (7, 8) each cooperate with an individual clutch (13, 14) respectively, by which one of the bevel gears can be locked to the intermediate shaft. The clutches (13, 14) are placed outside the bevel gearing, i.e. on the sides of the bevel gears (7, 8) facing away from each other in order to place the bevel gears (7, 8) close to each other. The clutches are wet clutches compressible by a piston (19) that moves in a cylinder (20) which in turn communicates with a hydraulic pump (22) driven by one of the input and intermediate shafts (2, 4). The output shaft (3) is driven by a bevel gear (12) having a recess in which one (14) of the clutches is partially received. The axis of the output shaft (3) intersects the axis of the intermediate shaft (4) at a point encircled by that latter clutch (14). |
