Abstract
The invention discloses a three-speed variable speed device. The three-speed variable speed device comprises an input shaft, an intermediate shaft and an output shaft. The right end of the input shaft is provided with an input tooth. The intermediate shaft is sequentially provided with a driven tooth, an intermediate tooth I and an intermediate tooth II from left to right. The output shaft is sequentially provided with an output tooth I and an output tooth II from left to right. The intermediate tooth I and the intermediate tooth II are matched with the output tooth I and the output tooth II correspondingly. The input tooth is matched with the driven tooth. Spline teeth are arranged on the output shaft, between the output tooth II and the output tooth I and on the left side of the output tooth I. The three-speed variable speed device further comprises shift fork rods which are connected with the spline teeth through shift forks correspondingly. According to the three-speed variable speed device, the structure is simple, and switching of different gears can be achieved through one single shift fork rod by arranging a plurality of clutches.
Description
Technical field
The present invention relates to Automatic transmission technical field, is related to a kind of speed change gear, more particularly to a kind of three fast speed change gear.
Background technology
Automotive transmission is a set of for coordinating the speed change gear of the actual travel speed of the rotating speed and wheel of electromotor, being used for
Play the optimum performance of electromotor.Variator can produce different changes between electromotor and wheel in vehicle traveling process
Speed ratio, can be such that electromotor is operated under its optimal power performance state by gearshift.Four-speed gear shift device generally existing is tied at present
Structure is complicated, is arranged to " H types ", unhandy determination its gear-change hand lever more.
The content of the invention
In view of this, the invention provides a kind of three fast speed change gear.
A kind of three fast speed change gear, including input shaft, jackshaft and output shaft, the input shaft right-hand member is provided with input tooth, described
Jackshaft is from left to right sequentially provided with driven tooth, center tooth I, center tooth II, the output shaft is left-to-right be sequentially provided with output gear I,
Output gear II, center tooth I, center tooth II are engaged with output gear I, output gear II respectively, described to be input into tooth and driven tooth
It is engaged；Spline tooth is respectively equipped with the output shaft, between output gear II and output gear I and on the left of output gear I, is also wrapped
Shifting fork bar is included, the shifting fork bar is connected with spline tooth respectively by shift fork.
Further, the input shaft is coaxially disposed with output shaft and input shaft right-hand member can be combined by spline tooth with output shaft left end.
Further, also include for supporting jackshaft and output shaft support, the shifting fork bar to be slidably arranged in pedestal upper end.
Further, the output gear I is provided with arrangement of clutch.
Further, center tooth I is directly less than center tooth II.
The beneficial effects of the present invention is：
The fast speed change gear simple structure of the three of the present invention, is capable of achieving by single shifting fork bar reality by arranging clutch and two spline tooths
The gear switch of existing difference.
Description of the drawings
In order that the object, technical solutions and advantages of the present invention are clearer, further is made to the present invention below in conjunction with accompanying drawing
Describe in detail, wherein：
Fig. 1 is three fast speed change gear structure chart of the present invention.
Specific embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in figure 1, the fast speed change gear of the three of the present embodiment, including input shaft 1, jackshaft 2 and output shaft 3, the input
1 right-hand member of axle is provided with input tooth 11, and the jackshaft 2 is from left to right sequentially provided with driven tooth 20, center tooth I21, center tooth II22,
The output shaft 3 is left-to-right to be sequentially provided with output gear I31, output gear II32, center tooth I21, center tooth II22 respectively with
Output gear I31, output gear II32 are engaged, and the input tooth 11 and driven tooth 20 are engaged；On the output shaft 3, it is defeated
Go out between tooth II32 and output gear I31 and on the left of output gear I31, be respectively equipped with spline tooth 6, also including shifting fork bar 5, described group
Fork arm 5 is connected with spline tooth 6 respectively by shift fork；The input shaft 1 be coaxially disposed with output shaft 3 and 1 right-hand member of input shaft with
3 left end of output shaft can be combined by spline tooth 5；Also include the support 4 for supporting jackshaft 2 and output shaft 3, described group
Fork arm 5 is slidably arranged in 4 upper end of support；The output gear I31 is provided with arrangement of clutch；Center tooth I21 is directly less than
Center tooth II22.
The fast speed change gear simple structure of the three of the present invention, is capable of achieving to realize different shelves by single shifting fork bar by arranging multiple clutches
Position switching.(now shifting fork bar II42 and shifting fork bar I41 one, shift handle can be configured as linear type)
Finally illustrate, above example only to illustrate technical scheme and unrestricted, although by referring to this
Invention has been described for bright preferred embodiment, it should be appreciated by those of ordinary skill in the art that can be in form
Various changes are made to which in upper and details, the spiritual and model of the present invention limited without departing from appended claims
Enclose.
