Working principle of the present utility model is, input shaft drives the second gear and rotates, spline housing on the second gear when spline on the output shaft separates, described the second gear and the engagement of the 3rd gear, then the second gear driven the 3rd gear rotates, the 3rd gear driven the 4th gear rotates, the 4th gear driven the first gear rotates, the first gear driven output shaft rotation, like this, just realize the output of the first rotating speed, the first gear and the second gear are for relatively rotating; When the spline housing on the second gear and the spline joint on the output shaft, described the second gear separates with the 3rd gear, then the second direct geared drives output shaft rotation, like this, just realize the output of the second rotating speed, this moment, output shaft drove the rotation of the first gear conversely, the first gear driven the 4th gear rotates, the 4th gear driven the 3rd gear rotates, and in this case, it all is idle running that the first gear, twin-stage gear are equivalent to.
After adopting said structure, the utility model compared with prior art, have the following advantages: in conjunction with technique scheme and working principle as can be known, when the mutual cooperation of each parts can the output of two kinds of rotating speeds, compact structure, component are few, annexation is simple and reliable, therefore, the utlity model has compact structure, simple advantage.
As improvement, described the first gear and the second gear can relatively rotate and refer to, be provided with a bearing between the first gear and the second gear, the inner ring of described bearing is connected with the second gear, the outer ring of described bearing is connected with the first gear, this linkage structure so that the gear shift gear is compact, simple, be convenient to install, and install fast.
As improvement, it also comprises the shift fork for mobile gear shift gear, and the spline housing on the first gear can move along the spline on the output shaft; Two projections on the shift fork lay respectively at the both sides of the first gear, this structure is used for integrated moving gear shift gear, namely during mobile shift fork, left side projection can promote the first gear to left movement, the first gear driven bearing and the second gear are to left movement, in like manner, the right projection can promote the first gear and move right, and the first gear driven bearing and the second gear move right, and this structure is on the one hand so that the gear shift gear is compact, simply, be convenient to produce, saved axial dimension, and this structure is easy to connect, firm, stressed better, on the other hand, provide convenience for mobile the second gear.
As improvement, described input shaft is Motor Shaft, directly with Motor Shaft as input shaft, make structure compacter, simple.
