Specific embodiment
As shown in Figure 1, this two speed transmission provided in this embodiment includes that the normal engaging tooth that is set in casing is two-way
Freewheel clutch 1, shunt assembly 2 and brake 3.
As shown in Fig. 2, often engaging tooth double rolling key clutch 1 includes fixed tooth 11, input tooth 12, transmission component 13 and defeated
Component 14 out.Fixed tooth 11 and input tooth 12 are the identical gear ring of specification, and fixed tooth is fixed in casing, and transmission component 13 is three
A long planet gear being distributed in gear ring, one end of long planet gear are engaged with fixed gear ring, and the other end is nibbled with input gear ring
It closes；Output link 14 is the planet carrier affixed with each long planet gear gear shaft.Same long planet gear one end and fixed gear ring
Engagement, the other end are engaged to be able to guarantee within the unit time, be turned over the planetary gear of fixed tooth engagement with input gear ring
The number of teeth and the ratio of the fixed tooth number of teeth be equal to the ratio of the number of teeth and the input tooth number of teeth that turn over the planetary gear of input tooth engagement
Value.
As shown in figure 3, shunt assembly 2 selects planetary gear set, input link 21 is sun gear, the first diverter member 22
For gear ring, the second diverter member 23 is planet carrier, and the inside of planetary gear 24 is engaged with sun gear, and outside is engaged with gear ring, planet
The gear shaft of frame and each planetary gear is affixed.When assembly, sun gear is connected with prime mover, and the first diverter member passes through connecting rod and output
Component is direct-connected, forms input link, planetary gear, the first diverter member to normal engaging tooth double rolling key clutch from shunt assembly
