The backward structure of case.
In order to solve the above technical problems, the utility model provides a kind of cross shaft driving gearbox having the following structure
Backward structure, including gearbox body, an axis, two axis and the driven gear wheel for being sleeved on two axis one end, are structurally characterized in that an axis
It is provided with reversing transmission mechanism between two axis.
The reversing transmission mechanism includes that be set on the axis inside gearbox body can be as a preferred technical solution,
The double crosslinking sliding gear slided on one axis is equipped with support shaft, support shaft in the gearbox body between an axis and two axis
On be set with bearing, bearing outside is equipped with duplicate gear.
The double crosslinking sliding gear includes first gear and second gear, first tooth as a preferred technical solution,
Fork slot is offered between wheel and the second gear.
As a preferred technical solution, shift fork is provided in the fork slot.
The duplicate gear includes third gear and the 4th gear as a preferred technical solution, the third gear with
The distance between described 4th gear is slightly larger than the thickness of the double crosslinking sliding gear.
The 4th gear is often to engage connection with the driven gear wheel as a preferred technical solution,.
After adopting the above technical scheme, due to including an axis and two axis in gearbox body, one end of two axis be equipped with from
In dynamic gear wheel gearbox body support shaft is installed between an axis and two axis, bearing is set in support shaft, bearing outside is equipped with
Duplicate gear, duplicate gear is free to rotate, and duplicate gear includes third gear and the 4th gear, the axis inside gearbox body
On be set with the double crosslinking sliding gear that can be slided on an axis, double crosslinking sliding gear includes first gear and second gear, the 4th
Gear is often to engage connection with driven gear wheel, and by the sliding of double crosslinking sliding gear, first gear engages control with third gear
Backward processed, the 4th gear and driven gear wheel conjugate control move ahead, and improve the work of tractor and various industrial amelioration products
Industry range and working efficiency.
Description of the drawings
The following drawings is only intended in doing schematic illustration and explanation to the utility model, does not limit the model of the utility model
It encloses.Wherein：
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the left view of Fig. 1.
Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass through
Bright mode describes certain exemplary embodiments of the utility model.Undoubtedly, those skilled in the art can be with
It recognizes, it, can be with a variety of different modes to described without departing from the spirit and scope of the utility model
Embodiment is modified.Therefore, attached drawing and description are regarded as illustrative in nature, rather than the protection for limiting claim
Range.
With reference to attached drawing, the backward structure of the cross shaft driving gearbox includes gearbox body 1, an axis 2, the power warp of engine
One axis 2 is incoming, and two axis 3 and the driven gear wheel 4 for being sleeved on two axis, 3 right end are provided with commutation transmission between an axis 2 and two axis 3
Mechanism, reversing transmission mechanism include being located at the duplex that is set with and can slide on an axis 2 on the axis 2 inside gearbox body 1 to slide
Gear 5 is moved, double crosslinking sliding gear 5 includes first gear 51 and second gear 52, the first gear 51 in left side and the second of right side
Fork slot 9 is offered between gear 52, stretches into the shift fork 10 that can stir double crosslinking sliding gear 5 in fork slot 9, in gearbox body 1
Support shaft 6 is installed, interference fit has bearing 7 in support shaft 6, and being interference fitted outside bearing 7 has duplex between one axis 2 and two axis 3
Gear 8, duplicate gear 8 can realize that free planetary rotation, duplicate gear 8 include the 4th tooth of the third gear 81 and right side in left side
Wheel 82, the distance between third gear 81 and the 4th gear 82 are slightly larger than the thickness of double crosslinking sliding gear 5, double crosslinking sliding gear 5
Thickness be to have the left side of first gear 51 to the distance of the right side of second gear 52, the 4th gear 82 and driven gear wheel
4 connect for often engagement, and shift fork 10 is stirred double crosslinking sliding gear 5 and moved to right, and second gear 52 is engaged with driven gear wheel 4, the second tooth
Wheel 52 drives driven 4 and two axis 3 of gear wheel rotation, tractor to realize that the forward working condition of full gear, shift fork 10 stir duplex cunning
Gear 5 to be moved to move to left, first gear 51 is engaged with third gear 81, since third gear 81 and the 4th gear 82 are duplicate gear 8,
4th gear 82 drives driven gear wheel 4 and two axis 3 to rotate, and tractor realizes full gear backward working condition, this structure is through
Have technology manipulate shift control, realize full gear move ahead or backward.
