Detailed description of the invention
As shown in Figures 1 to 4, present invention is disclosed the gear change system of a kind of outboard motor, including the drive shaft 6 being mutually permanently connected and driving gear 8, the described bottom driving gear 8 to be arranged at described drive shaft 6；Described driving gear 8 engages with a positive skiving wheel 12 and a reverse-gear 14 all the time, and described i.e. driving gear 8 drives positive skiving wheel 12 and reverse-gear 14 to rotate all the time.
One clutch 13 be arranged on described positive skiving wheel 12 and reverse-gear 14 between, can relatively described positive skiving wheel 12 and reverse-gear 14 move axially, and selectively with described positive skiving take turns 12 or reverse-gear 14 affixed.Described positive skiving wheel 12 and reverse-gear 14 are bevel gear.Namely when described clutch 13 and positive skiving take turns 12 affixed time, the rotational of described positive skiving wheel 12 drives the rotation of described clutch 13, and vice versa.
Described clutch 13 is socketed and is fixed on a clutch linkage 11, one end of described clutch linkage 11 is fixing with a cam slide 10 to be connected, the other end stretches in a propeller shaft 16, described clutch linkage 11 only circumferentially fixed with propeller shaft 16 and axially can relative movement, described propeller shaft 16 is fixed with propeller 15.
One shift bar and described drive shaft 6 be arranged in parallel, and the top of described shift bar is provided with gear shift driving mechanism.Described gear shift driving mechanism includes gear shift support 3, is slidably disposed on the gear shift slide block 1 on described gear shift support 3, moving axially of described gear shift slide block 1 drive the gear shift connecting rod 4 rotated, described gear shift connecting rod 4 connects described upper shift bar 5.Described gear shift support 3 is provided with neutral position sensor 2.Described shifter has concrete announcement in the Chinese patent CN202082379U that the applicant applies for, repeats no more in the present invention.
Described shift bar is formed by connecting by shaft coupling by upper shift bar 5 and lower shift bar 7, and a shifting cam 9 is arranged on lower shift bar 7 one end away from shaft coupling.Described gear shift driving mechanism drives described shift bar to rotate, and then drives described shifting cam 9 to rotate.
Described cam slide 10 is provided with a cam surface, the cam surface of described shifting cam 9 abuts with described cam surface, when described shifting cam 9 rotates, the cam surface of described shifting cam 9 drives described cam slide 10 to move axially, and drives moving axially of clutch linkage 11 and clutch 13.When described clutch 13 move axially to positive skiving take turns 12 affixed time, the rotational of described positive skiving wheel 12 drives the rotation of described clutch 13, and clutch 13 can drive propeller shaft 16 to rotate after rotating, and then drives described propeller 15 to rotate.
Further, in the preferred embodiment of the present invention, the base circle diameter (BCD) of shifting cam 9 is chosen for 14.224.In order to ensure stationarity during gear shift, along with the increase of angle, polar radius also at the uniform velocity increases, and its curvilinear equation is under polar coordinate.Its cartesian coordinate value is as follows with polar relation: 。
Therefore owing to the special of the profile of shifting cam 9 is chosen so that the gear shift of the present invention is more steady, and berth-changing strength also requires that less.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes of being formed, all falls within protection scope of the present invention.
