Description
Technical field
The present invention relates to gearbox field, more particularly to a kind of two grades of transfer case shift mechanisms.
Background technology
As shown in Figure 1, the method for changing speed of existing gearbox is to realize gear shift with separating by varying the engagement between gear
's.Figure below middle gear A1 is fixed on input shaft, and gear A 2, gear B 2, gear C 2 are fixed on jackshaft, gear B 1, gear
C1 is nested on output shaft by spending to be good for, and can be slided under the action of shift fork on output shaft.Gear A 1 is engaged with gear A 2
Realize that input shaft is rotated with jackshaft；Gear B 1 is engaged with gear B 2, and when gear C 1 is disengaged with gear C 2, output shaft, which rotates, to be realized
1 grade；Gear C 1 is engaged with gear C 2, and when gear B 1 is disengaged with gear B 2, output shaft rotates and realizes 1 grade；The deficiency of such a structure
Part, impact caused by gear shift are acted directly on gear, cause gear wear, the durability of gearbox and reliability compared with
Difference；3 pairs of gears are needed, part is more, and structure size is larger.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of two grades of transfer case shift mechanisms, overcome due to gear
Caused by directly engaging the shortcomings that gearbox gear foot wheel abrasion, the bulk life time and reliability of gearbox are improved；This structure passes through
Change gear shift mechanism, can realize two grades using two pairs of gears, it is not necessary to the jackshaft of conventional gearbox.Structure is more stepped up
Gather, and alleviate weight, reduce cost.
The technical solution adopted by the present invention to solve the technical problems is：A kind of two grades of transfer case shift mechanisms, it includes
Input shaft and output shaft；Preceding output gear and rear output gear are fixed with the output shaft；A left side is provided with the input shaft
Input gear and right input gear；The left input gear and right input gear are assemblied on input shaft by bearing respectively；Institute
State left input gear to engage with left output gear, the right input gear is engaged with right output gear gear teeth mouth；The left input tooth
Spline is provided with input shaft between wheel and right input gear；The spline upper sleeve has sliding block；The sliding block can be along spline
Move left and right；The right side of the left input gear sets mouth with teeth, and the left side of right input gear sets mouth with teeth；The sliding block
The left and right sides is also respectively arranged with tooth mouth.
Sliding block is moved to the left, and when the tooth mouth on the left of sliding block is engaged with the tooth mouth on the right side of left input gear, input shaft passes through
Left input gear and left output gear export power to output shaft.
Sliding block moves right, and when the tooth mouth on the right side of sliding block is engaged with the tooth mouth in the left side of right input gear, input shaft passes through
Right input gear and right output gear export power to output shaft.
Beneficial effects of the present invention：Two grades of transfer case shift mechanisms of one kind of the present invention, overcome since direct geared is nibbled
Caused by conjunction the shortcomings that gearbox gear foot wheel abrasion, gear engages no relative impact all the time, improves the bulk life time of gearbox
And reliability；This structure can realize two grades, it is not necessary to conventional gearbox by varying gear shift mechanism using two pairs of gears
Jackshaft.Structure is compacter, and alleviates weight, reduces cost.
Brief description of the drawings
Fig. 1 is the schematic diagram of existing gearbox gear-shift structure；
Fig. 2 is a kind of schematic diagram of two grades of transfer case shift mechanisms of embodiment.
Embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and is further retouched in detail
State, which is only used for explaining the present invention, and protection scope of the present invention is not formed and is limited.
Embodiment
As shown in Fig. 2, present embodiments providing a kind of two grades of transfer case shift mechanisms, it includes input shaft 1 and output shaft
2；Preceding output gear 5 and rear output gear 6 are fixed with the output shaft 2；Left input gear 3 is provided with the input shaft 1
With right input gear 4；The left input gear 3 and right input gear 4 are assemblied on input shaft 1 by bearing respectively；The left side
Input gear 3 is engaged with left output gear 5, and the right input gear 4 is engaged with right 6 tooth mouth of output gear；The left input tooth
Spline 7 is provided with input shaft 1 between wheel 3 and right input gear 4；Sliding block 8 is cased with the spline 7；The sliding block 8 can
Moved left and right along spline 7；The right side of the left input gear 3 sets mouth with teeth, and the left side of right input gear 4 sets mouth with teeth；
The left and right sides of the sliding block 8 is also respectively arranged with tooth mouth.
Two grades of transfer case shift mechanisms of one kind of the present embodiment, sliding block 8 are moved to the left, and the tooth mouth in the left side of sliding block 8 and a left side are defeated
When entering the tooth mouth engagement on the right side of gear 3, input shaft 1 is exported dynamic by left input gear 3 and left output gear 5 to output shaft 2
Power；Sliding block 8 moves right, and when the tooth mouth on the right side of sliding block 8 is engaged with the tooth mouth in the left side of right input gear 4, input shaft 1 passes through the right side
Input gear 4 and right output gear 6 export power to output shaft 2.
Two grades of transfer case shift mechanisms of one kind of the present embodiment, overcome gearbox gear caused by being engaged due to direct geared
The shortcomings that foot wheel abrasion, gear engage no relative impact all the time, improve the bulk life time and reliability of gearbox；This structure is led to
Change gear shift mechanism is crossed, can realize two grades using two pairs of gears, it is not necessary to the jackshaft of conventional gearbox.Structure is more stepped up
Gather, and alleviate weight, reduce cost.
Above-described embodiment should not in any way limit the present invention, all to be obtained by the way of equivalent substitution or equivalency transform
Technical solution all fall within protection scope of the present invention.
