Summary of the invention
The object of the invention is to for above-mentioned the problems of the prior art, a kind of simple in structure, handling ease, power takeoff easy to assembly, with low cost are provided.
To achieve these goals, the technical solution used in the present invention is: comprise the power takeoff housing that is provided with inner chamber and opening, on the opening of power takeoff housing, be separately installed with for the change-speed box of input power and lengthen tween drive shaft and the output gear shaft for outputting power, change-speed box lengthening tween drive shaft is arranged on the rear end of transmission output shaft; The afterbody that change-speed box lengthens tween drive shaft is provided with input driving gear, and the aft end face of input driving gear is provided with end-tooth;
The inner chamber of power takeoff housing is provided with power takeoff input shaft, the head of power takeoff input shaft is provided with input ring gear, the front end face of input ring gear is provided with the end-tooth that can engage with input driving gear aft end face, and on its circumference, be also provided with the Cylinder Gear that can often engage with the output gear being arranged on output gear shaft, the afterbody of output gear shaft is provided with output flange;
When input ring gear front end face completes and engages with the end-tooth of input driving gear aft end face, power passes to output gear shaft by the Cylinder Gear of input ring gear, finally exports by output flange.
The afterbody that described change-speed box lengthens tween drive shaft is ledge structure, connects input driving gear by the spring being enclosed within on ledge structure.
The rear end of described input driving gear is provided with the baffle plate for it being carried out to axial limiting.
It is shift fork that described input ring gear carries out with input driving gear the control part that end face engages.
Compared with prior art, input driving gear of the present invention is provided with end-tooth, input ring gear has end-tooth and Cylinder Gear simultaneously, the Cylinder Gear of input ring gear often engages with the output gear on output gear shaft, in the time that operation is put into gear in needs realization, only needing to promote input ring gear moves axially, when input ring gear front end face completes and engages with the end-tooth of input driving gear aft end face, change-speed box can be lengthened to transmission of power on tween drive shaft to input ring gear, and then pass to output gear shaft by input ring gear, finally export by output flange, compare with the mode that traditional power takeoff generally adopts Cylinder Gear to engage, the present invention inputs driving gear and directly adopts end-tooth to engage with ring gear, simple in structure, many parts are saved, handling ease, easy to assembly, with low cost.
Further, the afterbody that change-speed box of the present invention lengthens tween drive shaft is ledge structure, connect input driving gear by the spring being enclosed within on ledge structure, realize the elastic interaction of input driving gear with input ring gear engagement process, more be convenient to both end-tooth engagements, improved the reliability of power transmission.
Brief description of the drawings

In accompanying drawing: 1. power takeoff housing; 2. power takeoff input shaft; 3. bearing cap shim assembly; 4. output flange; 5. output gear shaft; 6. input driving gear; 7. change-speed box lengthens tween drive shaft; 8. spring; 9. baffle plate; 10. input ring gear.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Referring to Fig. 1, the present invention includes the power takeoff housing 1 that is provided with inner chamber and opening, on the opening of power takeoff housing 1, be separately installed with for the change-speed box of input power and lengthen tween drive shaft 7 and the output gear shaft 5 for outputting power; Change-speed box lengthens tween drive shaft 7 and is arranged on the rear end of transmission output shaft, and the afterbody that change-speed box lengthens tween drive shaft 7 is provided with input driving gear 6, and the aft end face of input driving gear 6 is provided with end-tooth; The afterbody that change-speed box lengthens tween drive shaft 7 is ledge structure, connects input driving gear 6 by spring 8 elasticity that are enclosed within on ledge structure, and the rear end of input driving gear 6 is also provided with the baffle plate 9 for it being carried out to axial limiting; The inner chamber of power takeoff housing 1 is provided with power takeoff input shaft 2, the head of power takeoff input shaft 2 is provided with input ring gear 10, the front end face of input ring gear 10 is provided with the end-tooth that can engage with input driving gear 6 aft end faces, input ring gear 10 engages by fork controls end face with input driving gear 6, input ring gear 10 is also provided with the Cylinder Gear that can often engage with the output gear being arranged on output gear shaft 5 on circumference, the afterbody of output gear shaft 5 is provided with output flange 4, and completes last assembling by bearing cap shim assembly 3.
Working process of the present invention is: the rear end of inputting ring gear 10 and be positioned at power takeoff input shaft 2 in the time that power takeoff is not worked, now input driving gear 6 by baffle plate 9 axial limitings, input ring gear 10 does not engage with the end-tooth of input driving gear 6, and power can not lengthen tween drive shaft 7 from change-speed box and transmit to the back-end; In the time that vehicle needs power takeoff work, power takeoff shift fork will be inputted ring gear 10 and promote forward, it is engaged with the end-tooth of input driving gear 6, the power of change-speed box lengthening tween drive shaft 7 just passes to input ring gear 10 by input driving gear 6 like this, and then power continues to pass to output gear shaft 5, last power is exported by output flange 4.The afterbody that change-speed box of the present invention lengthens tween drive shaft 7 is ledge structure, connect input driving gear 6 by spring 8 elasticity that are enclosed within on ledge structure, realize the elastic interaction of input driving gear 6 with input ring gear 10 engagement processes, more be convenient to both end-tooth engagements, improved the reliability of power transmission.
The present invention inputs driving gear and directly adopts end-tooth to engage with ring gear, compares with the mode that traditional power takeoff generally adopts Cylinder Gear to engage, simple in structure, has saved many parts, handling ease, easy to assembly, with low cost.
