Description
Technical field
The utility model belongs to the vehicle transmission field, relates to a kind of torque power takeoff.
Background technology
Power takeoff be lean on gear or power take-off shaft in the vehicle gear box provide power and outwards output a kind of obtain the mechanical device with transferring power.Gain impetus through power takeoff during vehicle operation, be used for other purposes.The lifting pump is exactly one and obtains the hydraulic efficiency gear of power through power takeoff, is used for the lifting railway carriage, realizes that it is widely used in special-use vehicles such as dumping car, fire extinguishing tanker, concrete mixer, refrigeration from unloading functions.
Relatively difficulty of power takeoff but receiving the restriction in space, present most of minicar, Light-duty Vehicle is installed; And the power gear of matching used 515 types and 520 type iso-variable velocity case power takeoffs is a helical teeth, causes power takeoff outputting power gear to separate with power gear, also is in the high-speed operation state when causing oil pump not use; Make vehicle power property weaken; Fuel oil consumption increases, inefficiency, and output gear and oil pump also decrease service life.
Summary of the invention
The purpose of the utility model is to provide a kind of torque power takeoff, and it can not change change speed gear box in limited space profile and in-to-in helical teeth output power taking structure realize freely getting, dividing of transmission.
The technical scheme that realizes the utility model is: a kind of torque power takeoff comprises housing and the transmission device that is connected with propulsion source, wherein; Driving wheel is meshed with the output gear of propulsion source, and second gear that is meshed with driving wheel is other to have the 3rd gear, and this gear has internally toothed annulus; Second, third gear is an one; With coaxial the 4th gear that also is provided with of second, third gear, it is secondary and be meshed with the internally toothed annulus of the 3rd gear or separate that this gear constitutes sliding block joint through spline and axle, and the 4th gear is provided with circular groove; Shift fork stretches into outside housing through sliding tray in the circular groove of the 4th gear, and the end of output shaft is the torque mouth.
And housing is provided with electric controller outward, and the outside branch of shift fork passes electric controller.
And the tail end of shift fork is provided with manual control handle.
And propulsion source is from motor vehicle gearbox.
The utility model has the advantages that; Even if the change speed gear box power take-off gear is a helical teeth; The power taking power gear of power takeoff still can freely be got, divide with the outputting power gear; Thereby problems such as also being in the high-speed operation state when avoiding oil pump not use, weakening vehicle power property, hydraulic oil service life is short has reduced fuel oil consumption, has improved work efficiency.In addition, the transmission space has been saved in the engaged transmission design of external tooth in adopting, and has solved the difficult problem that the limited mechanical equipment of power takeoff installing spaces such as minicar can't be installed power takeoff.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model.
Wherein, 1, housing, 1.1, sliding tray, 2, driving wheel, 3, second gear, the 4, the 3rd gear, 4.1, internally toothed annulus, the 5, the 4th gear, 5.1, circular groove, 6, output shaft, 6.1, spline, 7, shift fork, 8, electric controller, 9, manual control handle.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
The scheme that the utility model provides is that a kind of torque power takeoff comprises housing 1 and the transmission device that is connected with propulsion source; Wherein, Driving wheel 2 is meshed with the output gear of propulsion source, and there is the 3rd gear 4 on second gear, 3 sides that are meshed with driving wheel 2, and this gear has internally toothed annulus 4.1; Second, third gear is an one; With coaxial the 4th gear 5 that also is provided with of second, third gear, that to be cliding gear constitute sliding block joints through spline 6.1 and axle 6 to this gear is secondary and be meshed with the internally toothed annulus 4.1 of the 3rd gear 4 or separate, and the 4th gear 5 is provided with circular groove 5.1; Shift fork 7 stretches into outside housing 1 through sliding tray 1.1 in the circular groove 5.1 of the 4th gear 5, and the end of output shaft 6 is the torque mouth.
Outside the housing 1 electric controller 8 is set, the outside branch of shift fork 7 passes electric controller 8.
The tail end of shift fork 7 is provided with manual control handle 9.
Propulsion source is from motor vehicle gearbox.
During work, give driving wheel 2 like the propulsions source such as mouth of motor vehicle gearbox with transmission of power, driving wheel 2 drives second gear, 3 rotations that are engaged with.Second, third gear is an one, can one-body moldedly also can interfix.The 3rd gear 4 is with 3 rotations of second gear, and second, third gear dallies on output shaft.Promote manual control handle 9 through controlling electric controller 8 or user; Making the shift fork 7 that stretches into circular groove 5.1 promote the 4th gear 5 moves along spline 6.1; So that the 4th gear 5 is meshed with the internally toothed annulus 4.1 of the 3rd gear 4; The 4th gear 5 is followed 4 rotations of the 3rd gear immediately, because the effect of spline 6.1, the rotation of output shaft 6 can output power.Thereby transmission links to each other and reaches the purpose of power taking.
Separately during power, only need control electric controller 8 or user and dial and turn round and stretch out the hand moving control handle 9, shift fork 7 separates the 4th gear 5 with the internally toothed annulus 4.1 of the 3rd gear 4, can reach the purpose of cutting off power.
