Problems solved by technology
However, such a shift system has a complex structure, a large number of parts, and extremely inconvenient installation, and the transmission efficiency will also decrease after the number of transmission parts increases.
In addition, there is another problem that is difficult to solve in the industry, that is, the shifting operation is not smooth, and the user feels uncomfortable.

Embodiment Construction
[0024] Such as Figure 1 to Figure 4 As shown, the present invention discloses a gear shifting system for an outboard motor, comprising a drive main shaft 6 and a drive gear 8 fixedly connected to each other, and the drive gear 8 is arranged at the bottom end of the drive main shaft 6; Gear 8 is meshed with a spur gear 12 and a reverse gear 14 all the time, and the drive gear 8 drives the spur gear 12 and the reverse gear 14 to rotate all the time.
[0025] A clutch 13 is arranged between the spur gear 12 and the reverse gear 14, can move axially relative to the spur gear 12 and the reverse gear 14, and can be selectively fixed with the spur gear 12 or the reverse gear 14. catch. Both the spur gear 12 and the reverse gear 14 are bevel gears. That is, when the clutch 13 is fixedly connected with the spur gear 12, the rotation of the spur gear 12 can drive the rotation of the clutch 13, and vice versa.
[0026] The clutch 13 is socketed and fixed on a clutch connecting rod 11...

The invention discloses a gear shifting system of an outboard engine. The gear shifting system comprises a main driving shaft and a driving gear which are fixedly connected mutually as well as a clutch and a gear shifting lever, wherein the driving gear is always meshed with a clockwise-rotation gear and an anticlockwise-rotation gear; the clutch can be fixedly connected with the clockwise-rotation gear or the anticlockwise-rotation gear selectively; the gear shifting lever is parallel to the main driving shaft; a gear shifting cam is fixedly arranged at the bottom end of the gear shifting level, and when the gear shifting cam rotates, a cam surface of the gear shifting cam drives a cam sliding block to move axially, and drives a clutch connecting rod and the clutch to move axially. The gear shifting system has the obvious effects that 1, a signal can be generated in a neutral gear position directly, so that neutral start is ensured; 2, gear shifting is smoother, and smaller gear shifting force is required; 3, the structure is simple, the installation is convenient, and the transmission efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of marine outboard engines, in particular to a gear shifting system. Background technique [0002] In the ship's main propulsion device, in addition to the drive shafting, various other transmission equipment, such as a gear shift system, will be equipped between the engine and the propeller. The normal direction of the ship's engine is called forward driving; the opposite direction of the ship's engine is called reverse. The shifting system realizes the switching of the propeller between forward and reverse. [0003] The shifting system in the prior art generally includes a forward gear set, a reverse gear set and propellers arranged symmetrically at both ends, as disclosed in Chinese patent CN202848009U. However, such a shifting system has a complicated structure, a large number of parts, and extremely inconvenient installation, and when the number of transmission parts increases, the transmission effici...
